EP3080874B1 - Holding frame for a plug connector - Google Patents

Description

The invention relates to a holding frame for a connector according to the preamble of independent main claim 1.

Furthermore, the invention relates to a manufacturing method for a holding frame according to the preamble of independent subsidiary claim 13.

Furthermore, the invention relates to a method for introducing a module into a holding frame according to the preamble of the independent subsidiary claim 14.

Such support frames are required to accommodate a plurality of similar and / or different modules. These modules can be, for example, insulating bodies, which are provided as contact carriers for electronic and electrical and possibly also for optical and / or pneumatic contacts. Of particular importance is that the support frame is generically made of a metallic material, because this is required for the production of a regulatory protective grounding according to the connector standard EN61984, for example, for inserting the modules equipped with holding frame in metallic connector housing.

State of the art

From the publication EP 0 860 906 B1 a holding frame for mounting connector modules and for installation in connector housings or for screwing to wall surfaces is known, wherein the connector modules are inserted into the holding frame and holding means on the connector modules with at opposite wall parts (side surfaces) of the holding frame cooperate recesses provided, wherein the recesses are formed as all-round closed openings in the side surfaces of the holding frame, wherein the holding frame consists of two articulated halves, wherein the separation of the holding frame is provided transversely to the side surfaces of the frame, and wherein joints in the attachment ends the support frame are arranged such that when screwing the support frame to a mounting surface, the frame parts align such that the side surface of the support frame are aligned at right angles to the mounting surface and the connector modules have a positive connection with the support frame via the support means. In practice, such holding frames are usually produced in a die-casting process, in particular in a zinc die-casting process.

The publication EP 2 581 991 A1 discloses a support frame for connector modules having two frame halves which are latched together by linear displacement of a frame half relative to the other frame half in a sliding direction,
wherein mutually corresponding locking means are provided on the frame halves, the latching of the two frame halves effect each other in two different locking positions during linear displacement, in which the frame halves are spaced at different distances from each other.

However, it has been found in practice that such mounting frames require a complex operation during assembly. For example, such support frame must be unscrewed from the connector and / or unlocked as soon as a single module to be replaced. In this case, possibly fall the other modules whose removal was not desirable, out of the support frame and must then be reinserted before screwing together and / or before locking the frame halves. Finally, you need to be aware before joining the frame halves all modules are simultaneously in their intended position to be permanently fixed in the mounting frame when joining the frame halves, which makes mounting difficult.

The publication EP 2 228 871 A2 describes a connector with a body consisting of an insulator; a plurality of metal-made contacts held by the body; and a shield cover made of a metal plate.

The publication DE 27 36 079 A1 discloses a latchable terminal block or connection module for electrical leads, the terminal block being provided at its two end edges which run parallel to the longitudinal direction of a support rail for assembling such terminal blocks with grooves respectively co-operating with internal horizontal projections close to the free one Ends of the two legs of a metallic U-shaped carrier profile are provided, wherein the grooves can be used at different distances from the bottom of the profile against the action of at least one transverse leaf spring.

The publication WO 2008 121 092 A2 discloses an integrated shielded cage assembly for electrical connectors. The cage assembly has multiple panels for receiving electrical components. There are at least two Matrizenfelder provided, and the matrices are separated by a gap. The assembly is made with a plurality of spacers which mesh with a plurality of partitions, and cover structures are provided to ensure the shielding.

The publication WO 2011 069 522 A1 proposes a system connector which receives male modules with electrical contacts held therein which are first inserted vertically into a region of a support frame in which a plugged-in insert is arranged to be laterally displaced and held laterally by 90 ° in the support frame. In this case, the housing frame as a self-supporting part of the system connector for Recording the plug-in modules formed, and can be protected against environmental influences with a surrounding housing. Furthermore, the plug-in modules can be used against previously common arrangements in connectors on both sides, ie in the insertion direction or against the insertion direction in the support frame and removed again.

The publication WO 2008 121 092 A2 discloses a frame for multi-pin connector, consisting of a flange and an insertion part with lamellae formed thereon, which are formed from the bottom waste piece of the insertion part at its free end edge and bent onto the wall of the insertion part

The publication EP 1 801 927 B1 discloses a holding frame, which consists of a one-piece plastic injection molded part. The holding frame is formed as a circumferential collar and has on its side plug a plurality of separated by slots wall segments. Two opposite wall segments each form an insertion region for a plug-in module, wherein the wall segments have window-like openings, which serve to receive projections formed on the narrow sides of the modules. Furthermore, in each case a guide groove is provided in the wall segments. The guide groove is formed above the openings by means of an outwardly offset window web, which has an insertion bevel on the inside. In addition, the plug-in modules have latching arms, which act on the narrow sides in the direction of the cable connections, molded, and latch below the side collar wall, so that two independent locking means fix the connector modules in the support frame.

A disadvantage of this prior art, on the one hand, that it is a holding frame formed of plastic, which is not suitable for protective grounding, for example by a PE contact, so for example not suitable for installation in metallic connector housing. The use of metal connector housing sets such a protective ground however, and in many cases is necessary and therefore desired by the customer because of their mechanical robustness, temperature resistance and electrically shielding properties. Furthermore, it has been found that the production of such trained plastic holding frame by injection molding is at least difficult and re-alisieren at great expense. Finally, the heat resistance of such a support frame for special applications, for example in the vicinity of a blast furnace, is not always sufficient. Finally, the plastic material and the Shape, in particular the strength of the holding frame in the relevant places primarily determined by the requirements of the flexibility and not those of the temperature resistance.

task

The object of the invention is to provide a design and a manufacturing method for a holding frame, which on the one hand has good heat resistance and high mechanical robustness and in particular also when installed in a metallic connector housing a corresponding protective ground, in particular a PE ("Protection Earth") - Protective ground, allows and on the other hand, a comfortable operation, especially when replacing individual modules guaranteed.

This object is solved by the features of the independent claims.

Such a support frame is used in the field of heavy industrial connectors and consists at least partially of a metallic material, namely sheet, thus a protective ground, in particular a PE protective earth, allows, and at the same time allows due to the elastic properties of the sheet, modules individually with only very little effort to insert or remove. Furthermore, the use of sheet metal as a material ensures high temperature resistance and also ensures a particularly high mechanical robustness of the holding frame.

A resilient sheet is to be understood as meaning a sheet which has spring-elastic properties, such as, for example, a reversible deformability, in particular with the application of a corresponding restoring force, ie, for example, a sheet metal made of spring steel or a comparable material.

Advantageous embodiments of the invention are specified in the subclaims.

An advantage of the invention is therefore that the modules can be inserted individually and with very little effort in the support frame and removed from it.

It is particularly advantageous in particular if the modules have a cable connection side which is intended to be connected to a cable, e.g. by screwing, crimping, soldering or the like, and that the modules are inserted from the direction of their cable connection side in the support frame, because they can be completely removed in the wired state of the support frame back towards their cable connection side. This is especially true when installed, so even if the support frame is already installed in a connector housing, such as a Flanschanbaugehäuse. Another advantage therefore also lies in the fact that the cable can be prefabricated with the modules and, independently of the process of prefabrication, can only later be inserted into a holding frame. Also, the support frame can be replaced in this way, without the need to be separated from the cable modules, e.g. if the holding frame has wear and / or damage.

Another advantage of the invention is that the holding frame for electrical safety a protective ground, in particular a PE protective ground of a metallic connector housing, in which the holding frame is inserted, allows. This further ensures as an additional advantage, a shielding of the transmitted signals through the connector. This shielding can be a protection against interference from the outside act. But it can also be a shield to prevent or reduce an interference emission, so protect the environment against interference fields of the connector. In other words, not only are the signals transmitted by the modules protected from external interference fields, but environmental protection from disturbances also takes place, which is caused by current flowing through the modules.

A particularly great additional advantage is that the support frame is on the one hand particularly resistant to heat and on the other hand still has sufficient elasticity at the required points to insert the modules individually and with little effort in the module frame and remove again. It is particularly advantageous if the entire holding frame (or at least the functional part of the holding frame for holding and fixing the modules) consists of resilient sheet metal, because it is substantially more resistant to heat at least as great elasticity than a mechanical point of view otherwise functional comparable plastic frame. Associated modules can be made compact in their design accordingly, so that they can continue to be made of plastic and still are relatively resistant to heat.

It is particularly advantageous that both the material and the design of these modules need to show only low elasticity, because even the holding frame consists of a resilient sheet and therefore, for example, is able, the modules in a constant base voltage over a To keep longer period, without thereby fundamentally changing, for example without so much irreversible deformation and especially under constant mechanical and thermal stress to "crawl" so strong that its holding force with respect to the modules and / or for example, the Contact pressure to a mating connector and thus the optimal function of the connector would be called into question. In other words, the modules can be resiliently clamped in the holding frame without the modules themselves having to have elastic parts and / or material properties.

It is therefore particularly advantageous if the holding frame is at least partially made of resilient sheet metal, so at least partially consists of one or more resilient sheet metal parts. In particular, it can be produced in stamping and bending technology, so that the sheet metal part or parts are stamped and bent parts. This advantageously enables production with the tools customary for the stamping and bending technique, so that no special tools are necessary for producing such a holding frame. If the holding frame consists of several stamped and bent parts, then these stamped and bent parts can consist of the same sheet metal and accordingly have the same material properties, in particular the same elasticity to one another. But they can also be punched out of different sheets and have different material properties, in particular different strengths and / or elasticities.

The holding frame has a plurality of different areas, which have a different elasticity to each other, because then he can selectively apply a higher moment of resistance in the region of the highest bending stress. The first region with a higher resistance moment is thus a base section. The second region with a lower resistance moment is a deformation section.

This can be realized both with a holding frame, which consists of a single sheet metal part as well as with a holding frame, which consists of several sheet metal parts, wherein the sheet metal parts with each other may have the same or different material properties, in particular the same or different elasticities.

For example, a support frame consist exclusively of sheet metal parts, which consist of the same material and also have the same strength, that is, for example, are punched out of the same stamped sheet metal. For this purpose, a first of these areas, that is, for example, the basic section, from a consist of circulating base frame. The base frame may be substantially rectangular in cross-section, thus having two mutually parallel opposite end portions and perpendicular thereto two mutually parallel opposite side parts, wherein the end portions are shorter than the side portions. End and side parts can also be the same length in the special case of a square cross section.

By this closed shape already contributes to the geometry of the base frame and thus the geometry of the entire support frame that this first area, namely the base frame, a lower elasticity and thus greater strength than a second area, which for example from a cheek area with free-standing elastic tabs, which are separated by slots. In particular, this applies if the holding frame is firmly mounted in a connector housing, for example screwed into four screw holes in the connector housing. In addition, the sheet metal of the holding frame in the first area, namely the base frame, at least in some places, in particular on the side parts and possibly also on the end faces, be selectively reinforced by there different layers of the same sheet metal part, for example by folding or by other layers at least one other sheet metal part by attaching and attaching, so come through a so-called joint connection, flat to each other. In the case of the joining connection, called "joining" for short, these sheet metal parts are fastened together at one or more suitable locations, for example by gluing, welding, soldering, riveting or any other suitable fastening method.

The associated modules may be formed substantially parallelepiped-shaped and have on two opposite longitudinal sides in each case a latching lug, which may also be performed substantially cuboidal. Each of the elastic tabs of the holding frame advantageously has a latching window, which may be formed substantially rectangular, and which is provided for preferably positive reception of such a latching lug.

The two locking lugs of a module may, for example, in their shape and / or size, in particular by their length, differ from each other and the tabs on both sides of the support frame may have corresponding (eg rectangular) windows, which therefore also differ from each other and which fit in size and / or shape to each one of the locking lugs. This has the advantage that thereby the orientation of each module is fixed in the holding frame. In other words, the latching window and the locking lugs can be used by their shape and / or size as coding means for orientation of the modules in the holding frame.

The tabs of the holding frame are advantageously bent away easily in a free-standing end portion of the support frame, which simplifies the insertion of the modules. The insertion of a module into the holding frame is then particularly user-friendly. For this purpose, a module is first introduced between two tabs of a holding frame and then slides along with its two longitudinal sides and in particular with the locking lugs formed thereon along the bent away end regions of the tabs. As a result, the two tabs bend momentarily further apart until the respective latching noses are received by the associated latching window of the respective tab and thus, in particular audibly, lock into it. When receiving the locking lugs in the respective locking window, the tabs preferably spring back into their starting position. In this way, the modules individually in the holding frame, preferably audibly, lock.

At the same time, the inserted module is held in the stable base frame with a comparatively large force, in particular when the holding frame is fixedly mounted in a connector housing, for example screwed into the connector housing at four screw holes. To unlock the modules again, only the two opposite elastic tabs have to be bent away from each other again. Then the respective module can be removed individually from the holding frame, while the other modules are still locked. Furthermore, a high holding force at a comparatively low operating force is ensured in this way, in particular by the different elasticity of the different areas, which is particularly advantageous for the operability.

A further ease of operation is given when the latching of the locking lugs in the locking windows generates a noise, because thereby the user is also acoustically signaled the correct positioning of the module.

It is particularly advantageous, moreover, that the modules are already held by the aforementioned construction with sufficient holding force in the holding frame and accordingly except their locking lugs no further locking means, for example, latching arms, because this simplifies their design and thus their production cost considerably and ensures at the same time a compact design and thus also for high heat resistance of the modules and thus the entire connector.

Of particular advantage in the production of the holding frame, that the sheet metal part or the sheet metal parts are shaped, in particular punched and bent and / or joined together, that some of their areas come to rest on each other and thereby for the functions provided in their spring force and possibly strengthen their holding power.

Thus, the sheet can in some places, for example by folding a sheet metal part and / or by joining several individual sheet metal parts, reinforced, for example doubled in strength, tripled, quadrupled, ..., etc., so ver-n-times be. As a result, the manufacturing advantages of the stamping and bending technique can be combined with a targeted influencing of the elasticity, which is otherwise difficult to implement, in particular if the same stamped sheet is used, which originally has a constant thickness. By folding and / or joining, on the one hand, a resilient sheet can be used as a particularly suitable material for the holding frame On the other hand, the elasticity of individual areas of the holding frame can also be selectively influenced in the manner described above, using a single stamping sheet, which facilitates the production.

In an advantageous embodiment, for example, the side parts of the base frame can be reinforced. For this purpose, a cheek area can additionally be provided adjoining each side face adjacent thereto, which has a reinforcing area and, in addition, protruding, adjoining or overlapping tabs. The cheek area can be bent with its reinforcing region in a bending operation by 180 ° and so folded over the side surface and reinforce this side surface against outwardly acting forces. In the further course, the cheek area can have, in whole or in some sections, slots which subdivide it into equidistant intervals along the side parts, the width of these intervals advantageously corresponding to the width of the modules. The slots can extend into the reinforcement area. Through the slots in one direction over the base frame protruding tabs are formed. In an opposite direction, the side parts of the base frame reinforced in this way can also project with their respective bending edge over the end faces. Thus, the side parts have a greater width than the end faces. This has the advantage that the modules are held over a larger area and in particular via a corresponding leverage effect with an increased holding force in the holding frame.

Thus, the folded cheek area protrudes with its free-standing end unreinforced beyond the base frame and thus forms the much more elastic second area, which can be regarded as a deformation section, for example. Due to its slots, this is done in particular by the individual, free-standing, elastic tabs, which already have a comparatively large elasticity due to their shape. The tabs are still preferably formed in contrast to the base frame of only a single, unreinforced sheet, so are not reinforced by a second plate, and thus have only the simple strength of this single sheet and thereby a greater elasticity than the first area. In addition, the tabs in the region of their slots are advantageously not themselves attached to the side surface but only connected to the side surface via the bending edge of the reinforcing region. This has the advantage that the tabs have a high elasticity against outward-acting forces, while the side parts in the region of the base frame oppose outward forces a great stability, since they are reinforced by the reinforcing regions. Since the tabs are connected to the side surface only by the reinforcing region on the common bending edge, they spring outwardly unreinforced over their entire length, whereas the side surfaces against outward forces by the reinforcing regions, and thus in particular by a corresponding overlap region of the tabs, are reinforced.

In an advantageous embodiment, only a single sheet metal part is used for the production of the holding frame. Then, each end face can be reinforced, for example, by stamping in each case additionally a reinforcing surface adjacent to each end surface during the blanking of the sheet, which is then bent by 180 ° and thereby folded over the end face in order to reinforce it and thus stabilize the base frame additionally. Furthermore, this reinforcing surface can be bent at right angles at a then projecting beyond the end face end, so that at the end of the end face a free-standing flange is formed, which may have, for example, in a connector, Schraubbohrungen. For stabilization, this flange can be reinforced in a similar manner, namely by folding or joining.

In an alternative advantageous embodiment of the flange can connect directly to the unreinforced face and bent at right angles to it. Then, on the one hand, the end face is not reinforced, but on the other hand, both material and a corresponding operation in the production saved. Furthermore, regardless of this, the side surfaces may nevertheless be reinforced, which is of paramount importance for holding the modules.

Furthermore, a variety of other embodiments is conceivable in which the holding frame is formed from a plurality of identical and / or different resilient sheet metal parts, which are fastened to each other for example by gluing, welding, soldering, screws and / or rivets. In particular, these sheet metal parts can be produced in stamping and bending technology, so that the sheet metal parts are stamped and bent parts. Preferably, the holding frame of two, in cross-section of the base frame substantially U-shaped sheet metal parts may be formed, which thus each have two end faces, namely a first and a second end face. The two sheet metal parts are then offset in the production of the holding frame in such a way, in particular offset by a sheet thickness, pushed into each other, that their first and second end faces each lie on each other and to each other, for example by gluing, welding, soldering, screws and / or rivets be attached. In particular, in each case the first end face of one of the sheet metal parts comes to rest on the second end face of the respective other sheet metal part and is fastened thereto. This embodiment has, in addition to the resulting reinforcement of the sheet in the region of the end faces, the further advantage that the holding frame in the region of its base frame in this way is closed over a large area and therefore in a very stable manner.

By screwing the holding frame to the screw holes of its flanges, for example, in or on a connector housing, the base frame is still significantly stabilized.

At one edge of the respective first end face thus coming out in turn, a flange, possibly with screw holes, similar to that described above, can then be bent at right angles. In a further advantageous refinement, the second end faces may additionally have a reinforcing flange which, when assembled on the flange of the first end face comes to rest and for reinforcement thereto, for example by gluing, welding, soldering, screws and / or rivets is attached. As a result, the flange of the holding frame is designed to be particularly stable.

In an advantageous embodiment, the two sheet metal parts are similar, i. Despite the two-part design of the holding frame, it is only necessary to produce sheet metal parts of one type, which further reduces the production outlay.

In another preferred embodiment, the two sheet metal parts differ at least by the size and / or the shape of their locking window. This has the advantage that thereby the orientation of each module, which accordingly has two different locking lugs, is fixed. In other words, the latching window and the latching lugs can thus serve by their shape as coding means for the orientation of the modules.

In a further preferred embodiment, the holding frame may consist of more than two sheet metal parts, in particular stamped bent parts, which are fastened to one another, for example by gluing, welding, soldering, screws and / or rivets.

The first sheet metal part 1 has the following:

• Two end faces 11, 11 ', namely a first end face 11 and a second end face 11';
• two side surfaces 12, 12 ', namely a first side surface 12 and a second side surface 12', wherein the side surfaces 12, 12 'are both wider and longer than the end surfaces 11, 11' and thus in the direction of the respective first bending line A, A ', A "beyond the adjoining end face 11, 11'protrude;
• eight free-standing tabs 13, 13 ', each having a latching window 131, 131', wherein the tabs 13, 13 'by slots 18, 18' are separated from each other, wherein the number of tabs 13, 13 'and the corresponding number of Slots 18, 18 'are selected by way of example and wherein the locking window 131 in four of the tabs 13 is wider than the locking window 131' in the other four tabs 13 ';
• two reinforcing regions 14, 14 'adjoining a boundary line E, E' on the one hand and a second bending line B, B 'on the respective side surfaces 12, 12' on the other hand;
• two to the respective end face 11, 11 'at a third bending line C, C' adjacent reinforcing surfaces 15, 15 ', and
• in each case one of the respective reinforcing surface 15, 15 'at a fourth bending line D, D' adjacent flange 17, 17 ', the screw holes 171, 171 has.

At the dashed lines illustrated second and third bending lines B, B ', C, C', the first sheet metal part 1 is folded by 180 °. As a result, each of the two reinforcing regions 14, 14 'comes to lie on one of the side surfaces 12, 12' and each of the two reinforcing surfaces 15, 15 'comes to lie on one of the end surfaces 11, 11' around the respective side surface 12, 12 'or the end face 11, 11' amplify accordingly. The dashed line delineation E, E 'thus represents a limit from which the tabs 13, 13' then protrude beyond the respective side surface 12, 12 '. The respective reinforcing region 14, 14 'is connected to the associated side surface 12, 12' only at the common second bending line B, B ', so it is not otherwise attached thereto, so not glued, soldered, welded, riveted, screwed or the like.

As a result, the tabs 13, 13 'have a correspondingly high flexibility, since they are over their entire length, i. into the reinforcing region 14, 14 ', are individually bendable away from the side surface 12, 12'. By the length of the slots 18, 18 'is thus the length and thus the desired elasticity of the tabs 13, 13' adjustable.

Together, the tabs 13, 13 'and the further reinforcing region 14, 14' are referred to as cheek area, which is not provided with a reference numeral for reasons of clarity. The cheek area is thus largely divided by the six slots 18, 18 'in equal intervals, whereby the tabs 13, 13' are formed, so that the length of the tabs 13, 13 'corresponds to the length of the slots 18, 18'. The term "largely" in this context means that the slots 18, 18 'and thus also the tabs 13, 13' extend beyond the boundary line E, E 'into the respective reinforcement area 14, 14', but are preferred before the second bending line B, B 'ends. In other words, at least part of the reinforcing area 14, 14 'is formed by the tabs 13, 13'. As a result, there is an overlapping area which is attributable both to the tabs 13, 13 'and to the reinforcing area 14, 14', namely that area of the tabs 13, 13 'that lies between the boundary line E, E 'and the second bending line B, B' is located. This overlapping region thus has a dual function, because it serves on the one hand to increase the stability of the base frame and on the other hand to increase the elasticity of the tabs 13, 13 'with respect to outwardly acting forces. In particular, this applies if the holding frame firmly mounted in a connector housing, for example, at its four screw holes 171, 171 'is screwed into the connector housing.

The side surfaces 12, 12 'protrude beyond the end faces 11, 11' in the folded state with one of their respective bending edge corresponding to the second bending line B, B '.

The first sheet-metal part 1 is bent at right angles at the first and fourth bending lines A, A ', A ", D, D', which are also shown in dashed lines, and the respective flange 17, 17 'is formed by the right-angled bending at the fourth bending lines D, D' which for fastening, for example, on or in a connector housing not shown in the drawing, the Schraubbohrungen 171, 171 'The right-angled bending of the sheet metal part 1 to the first bending lines A, A', A "provides the closed shape of a base frame, which thus formed from the end faces 11, 11 'and the side surfaces 12, 12', reinforced by the reinforcing surfaces 15, 15 'and the reinforcing regions 14, 14', that is, two end parts and two side parts. This right-angled bending takes place in such a way that the cheek area is arranged outside the base frame, that is to say on the outside of its side face 12, 12 '.

In order to fix the closed shape of the base frame, the second side surface 12 'still has to be fastened to the first end face 11, for example by gluing, welding, soldering, screwing, riveting or the like. Advantageously, this is done by setting multiple welds.

The reinforced by the first reinforcing surface 15 first end face 11 thus forms the first end portion of the base frame. The through the second reinforcement surface 15 'reinforced second end face 11 further forms the second end portion of the base frame. Together with the two right angles thereof bent side parts, formed from the two side surfaces 12, 12 ', which are reinforced by the respectively associated reinforcing regions 14, 14', these two end parts form the base frame.

The Fig. 1b shows in a variant of the first embodiment, a second sheet metal part 1 'in an unbent state.

The second sheet metal part 1 'differs from the first sheet metal part in that it has no reinforcing surfaces 15, 15' and correspondingly no associated third bending line C, C ', whereby the respective flange 17, 17' with its screw holes 171, 171 ', the thus over the fourth bending line D, D 'to the corresponding end face 11, 11' adjacent. Thus, the second sheet metal part 1 'has the following:

• The two end faces 11, 11 ', namely the first end face 11 and the second end face 11';
• two side surfaces 12, 12 ', namely the first side surface 12 and the second side surface 12', wherein the side surfaces 12, 12 'are both wider and longer than the end surfaces 11, 11' and thus in the direction of the respective first bending line A, A ', A "beyond the adjoining end face 11, 11'protrude;
• the eight free-standing tabs 13, 13 ', each having a latching window 131, 131', wherein the tabs 13, 13 'by slots 18, 18' are separated from each other, wherein the number of tabs 13, 13 'and the corresponding number thereof the slots 18, 18 'are chosen by way of example and wherein the latching window 131 in four of the tabs 13 is wider than the latching window 131' in the other four tabs 13 ';
• the two on the one hand to the boundary line E, E 'and on the other hand to the second bending line B, B' adjacent reinforcing regions 14, 14 ';
• in each case the above-mentioned flange 17, 17 ', which adjoins the respective end face 11, 11' on the bending line D, D ', and the Schraubbohrungen 171, 171' has.

At the dashed lines shown second bending lines B, B ', the second sheet metal part 1' is folded by 180 °. As a result, each reinforcing region 14, 14 'comes to rest on one of the side surfaces 12, 12', in order to correspondingly reinforce the respective side surface 12, 12 '. The dashed line E, E 'thus represents the limit from which the tabs 13, 13' then protrude beyond the respective side surface 12, 12 '. The respective reinforcing region 14, 14 'is connected to the associated side surface 12, 12' only at the common bending line, namely at the second bending line B, B ', and accordingly not otherwise attached thereto, that is not glued, soldered, welded, riveted or similar. As a result, the tabs 13, 13 'have a correspondingly high flexibility, since they are over their entire length, i. into the reinforcement region 14, 14 ', are individually bendable away from the side surface 12, 12'. By the length of the slots 18, 18 'is thus the length and thus the desired elasticity of the tabs 13, 13' without change in the material adjustable.

Together, the tabs 13, 13 'and the further reinforcing region 14, 14' are referred to as cheek area, which is not provided with a reference numeral for reasons of clarity. The cheek area is thus largely divided by the six slots 18, 18 'in equal intervals, whereby the tabs 13, 13' are formed, so that the length of the tabs 13, 13 'corresponds to the length of the slots 18, 18'. The term "largely" in this context means that the slots 18, 18 'and thus also the tabs 13, 13' extend beyond the boundary line E, E 'into the respective reinforcement area 14, 14', but are preferred before the second bending line B, B 'ends. In other words, at least part of the reinforcing area 14, 14 'is formed by the tabs 13, 13'. As a result, there is an overlapping area which is attributable both to the tabs 13, 13 'and to the reinforcing area 14, 14', namely that area of the tabs 13, 13 'which lies between the boundary line E, E' and the second bending line B, B '. lies. This overlapping region thus has a dual function, because it serves on the one hand to increase the stability of the base frame and on the other hand to increase the elasticity of the tabs 13, 13 'with respect to outwardly acting forces. In particular, applies This is when the holding frame firmly mounted in a connector housing, for example, at its four screw holes 171, 171 'is screwed into the connector housing.

The side surfaces 12, 12 'protrude beyond the end faces 11, 11' in the folded state with one of their respective bending edge corresponding to the second bending line B, B '.

The sheet metal part 1 is bent at right angles at the first and fourth bending lines A, A ', A ", D, D', which are also shown in dashed lines, and the flange 17, 17 'is formed by the right-angled bending at the fourth bending lines D, D'. that for fastening, for example, on or in a connector housing not shown in the drawing, the Schraubbohrungen 171, 171 'The right-angled bending of the sheet metal part 1' to the first bending lines A, A ', A "provides the closed shape of a base frame, which characterized by the end surfaces 11, 11 'and side surfaces 12, 12', reinforced by the reinforcing regions 14, 14 ', is formed. This right-angled bending takes place in such a way that the cheek area is arranged outside the base frame, that is to say on the outside of its side face 12, 12 '.

In order to fix the closed shape of the base frame, the second side surface 12 'has to be fixed to the first end surface 11, for example by gluing, welding, soldering, screwing, riveting or the like. In particular, this can be done by multiple welds.

Since a holding frame according to the above embodiments can be formed solely from a single, one-piece stamped and bent part, the first and the second sheet metal part 1, 1 'is particularly well suited for machining the holding frame 4.

The unreinforced first end face 11 thus forms in this embodiment, the first end portion of the base frame. The unreinforced second end face 11 further forms the second end part of the base frame. Together with the two orthogonal thereof bent side surfaces 12, 12 ', which are reinforced by the respectively associated reinforcing regions 14, 14', these two end parts form the base frame.

The Fig. 2a and the Fig. 2b show in a second embodiment, two further sheet metal parts 2, 2 ', namely a third sheet metal part 2 and a fourth sheet metal part 2'. Apart from the size of their windows 231, 231 ', the two further sheet metal parts 2, 2' in the present example may be similar to each other, which also simplifies their manufacturing process.

These two further sheet metal parts 2, 2 'each have the following:

• A side surface 22, 22 'which delimits from a first end face 21, 21' by the first bending line A, A 'and projects beyond the end face 21, 21' in the direction of this first bending line A, A ';
• a reinforcing region 24, 24 'bordering on the side surface 22, 22' on the one hand on the second bending line B, B 'and on the other hand delimited by the delimiting line E, E';
• a second end face 25, 25 'adjacent to the side surface 22, 22' at the third bend line C, C ';
• four free-standing tabs 23, 23 ', each having a latching window 231, 231', wherein the tabs 23, 23 'by slots 28, 28' are separated from each other, wherein the number of tabs 23, 23 'and the corresponding number of Slots 28, 28 'are selected by way of example and wherein the locking window 231 in four of the tabs 23, which belong to the third sheet metal part 2, larger, in particular wider, than the locking window 231' in the other four tabs 23 ', the fourth sheet metal part. 2 'belong;
• a flange 27, 27 'adjoining the first end face 21, 21' with a fourth bending line D, D ', wherein the flange 27, 27' has screw holes 271, 271 '.

At the dashed lines shown second bending lines B, B ', the third and fourth sheet metal part 2, 2' is folded in each case by 180 ° in a first direction. As a result, each reinforcement region 24, 24 'comes on in each case one of the side surfaces 22, 22 'lie to reinforce the respective side surface 22, 22' accordingly. The dashed line E, E 'thus represents the limit from which the tabs 23, 23' then protrude beyond the respective side surface 22, 22 '.

The respective reinforcing region 24, 24 'is connected to the associated side surface 22, 22' only at the common bending line, namely at the second bending line B, B ', and accordingly not otherwise attached thereto, that is not glued, soldered, welded, riveted or similar. As a result, the tabs 23, 23 'have a correspondingly high flexibility, since they are over their entire length, i. into the reinforcement region 24, 24 ', are individually bendable away from the side surface 12, 12'. By the length of the slots 28, 28 'is thus the length and thus the desired elasticity of the tabs 23, 23' adjustable.

Together, the tabs 23, 23 'and the reinforcing region 24, 24' are referred to as cheek area, which is not provided with a reference numeral for reasons of clarity. The cheek area is thus largely divided by the six slots 28, 28 'in equally large intervals, whereby the tabs 23, 23' are formed, so that the length of the tabs 23, 23 'corresponds to the length of the slots 28, 28'. The term "largely" in this context means that the slots 28, 28 'and thus also the tabs 23, 23' extend beyond the boundary line E, E 'into the respective reinforcement area 24, 24', but protrude the second bending line B, B 'ends. In other words, a part of the reinforcing area 24, 24 'is formed by the tabs 23, 23'. As a result, there is an overlapping area which is attributable both to the tabs 23, 23 'and to the reinforcing area 24, 24', namely that area of the tabs 23, 23 'which is located between the boundary line E, E' and the second bending line B, B '. lies. This overlapping region thus has a dual function, because it serves on the one hand to enhance the stability of the base frame and on the other hand to increase the elasticity of the tabs 24, 24 'with respect to outward-acting forces. In particular, this applies if the holding frame firmly mounted in a connector housing, for example, at its four screw holes 271, 271 'is screwed into the connector housing.

The side surfaces 22, 22 'protrude beyond the respective first end face 21, 21' in the folded state with one of their respective bending edges corresponding to the second bending line B, B '.

At the also shown in broken lines first, third and fourth bending lines A, A ', C, C', D, D 'these two sheet metal parts 2, 2' bent at right angles. The right-angled bending of the two sheet-metal parts 2, 2 'around the first bending lines A, A' and around the third bending lines C, C 'takes place in a second direction, which is opposite to the first direction, and thus ensures the U-shape of the sheet metal parts 2, 2 ', which in each case of the side surfaces 22, 22', the first end face 21, 21 'and the second end face 25, 25' is formed. As a result, the cheek area is on an outside, i. at one of the bent end faces 21, 25, 21 ', 25' opposite side of the respective side surface 22, 22 ', respectively. By the right-angled bending at the fourth bending lines D, D 'is in each case the flange 27, 27' is formed, which for fastening, for example, or in a connector housing not shown in the drawing, the screw holes 271, 271 'has.

The Fig. 2 c and 2 d represent two modified sheet metal parts 2 ", 2"', namely a fifth sheet metal part 2 "and a sixth sheet metal part 2"',. These two modified sheet metal parts 2 ", 2 '" differ from the third sheet metal part 2 and the fourth sheet metal part second 'in that they have at their respective second end face 25, 25' in each case via a further associated fifth bending line F, F 'an additional reinforcing flange 29, 29' with corresponding screw holes 291, 291 '.

The Fig. 3 a shows the two further sheet metal parts 2, 2 ', namely the third sheet metal part 2 and the fourth sheet metal part 2' in the bent state, whereby they each have the said U-shape and thereby together to form a holding frame, such as in Fig. 5 can be joined together, by being offset against each other by a sheet thickness so pushed into each other, that their first end faces 21, 21 'and their second end faces 25', 25 each come to rest on each other and glued together over a large area, soldered, welded, riveted or screwed or otherwise can be attached.

On the one hand, in this way the holding frame is reinforced in the region of the end faces 21, 21 '. The first reinforced end face 21 forms the first end part. The second reinforced end face 21 forms the second front part. On the other hand, a base frame is produced from the two face parts and the two side surfaces 22, 22 'reinforced by the respective reinforcing regions 24, 24', which by attaching the second end faces 25, 25 'to the first end faces 21', 21 over a large area Therefore, closed in a very stable manner and also for this reason has a special strength. In particular, this applies if the holding frame firmly mounted in a connector housing, for example, at its four screw holes 271, 271 'is screwed into the connector housing. Furthermore, the base frame in the region of its lateral surface 22, 22 ', in particular in relation to outward-acting forces, is stabilized by the respective reinforcing region 24, 24'.

In other words, the base frame thus formed has a particularly high strength both by its closed shape and by the reinforcement of its material at the end and side surfaces 22, 22 ', 21, 21', in particular when the holding frame is fixedly mounted in a connector housing , For example, at its four screw holes 271, 271 'is screwed into the connector housing. The tabs 23, 23 ', however, can over their entire length, which corresponds to the length of the associated slots 28, 28' unreinforced bent away from the associated side surface 22, 22 'and thus have respect to the base frame outwardly acting forces a particularly large Elasticity on. For example, in such a, in particular in the connector housing built or otherwise at its screw holes 271, 271 'fixed, holding frame a larger force on the side surface 22' engage to push them by a certain path length to the outside, as on the tab 23 ' ,

Furthermore, a further embodiment not shown in the drawing is conceivable in which the support frame consists of more than two parts. For example, such a part may consist of a flange and a reinforcing surface, wherein the flange is then bent at right angles from the reinforcing surface. This reinforcing surface is then attached to an end face of the preferably one-piece base frame, for example glued, soldered, welded, riveted or screwed. Another part can then form, for example, the cheek area. This further part can then be attached to a side surface of the base frame. However, it is important to make sure that the tabs continue to be wegbiegbar over its entire length of the associated side surface despite this attachment.

The Fig. 3 b shows the two modified sheet metal parts 2 ", 2"', namely the fifth sheet metal part 2 "and the sixth sheet metal part 2"' in each case in a bent state in one of Fig. 3 a comparable presentation. These two modified sheet-metal parts 2 ", 2 '" differ from the curved further modules 2, 2' in that the two modified sheet-metal parts 2 ", 2 '" each have at their second end face 25, 25' a reinforcing flange 29, 29 bent at right angles 'with associated screw holes 291, 291' have.

It is readily apparent that when joining the two bent modified sheet metal parts 2 ", 2 '" of the respective flange 27, 27' and the reinforcing flange 29, 29 'as the first and second end faces 21, 21', 25, 25 'area come to rest on each other and thus attached to each other, for example, glued, soldered, welded, riveted or screwed, can be.

The Fig. 4 a and the Fig. 4 b show an insertable into the holding frame module 3 in a possible design of two different views, but each with a view of its mating side. Of course, other modules in similar design can be used.

The module 3 has on a first longitudinal side 32 a first latching lug 31, which is provided for latching in a first latching window 131, 231, 431. At a this first longitudinal side 32 opposite the second longitudinal side 32 ', the module 3 has a second latching lug 31', which is narrower than the first latching lug. Furthermore, the module is very compact, which improves its heat resistance. Due to the shape of the latching lugs 31, 31 'and the shape of the windows 131, 131', 231, 231, 431, 431 ', the orientation of the module 3 is fixed in the holding frame.

The Fig. 5 shows a holding frame consisting of the two other sheet metal parts 2, 2 ', namely the third sheet metal part 2 and the fourth sheet metal part 2', as shown in the Fig. 2a . Fig. 2b and Fig. 3 are shown formed. In another embodiment, it could also consist of a single first sheet-metal part 1, 1 'as shown in FIG Fig. 1a and Fig. 1b are shown, or alternatively from a variety of items, ie consist of more than two items.

This holding frame has a first area B1, formed from the rectangular cross-section base frame, and a second area B2, formed from the two outer cheek areas. The first area B1 can be regarded as the basic section. The second region B2 can be regarded as a deformation section.

It can easily be seen that the cheek areas with their respective reinforcing area 24, 24 'reinforce the base frame against outward forces, but can bend away unreinforced even to the outside. In particular, the tabs 23, 23 'together with their overlap region can be bent away from each other independently with a relatively small force.

Advantageously, the built-in a connector housing, so at its screw holes 271, 271 'fixed base frame so, for example, at the center of its side surfaces 22, 22' an outward deflection oppose a force that is greater than the force that is necessary to move a tab 23, 23 'in the region of its window by the same path length to the outside.

From the perspective shown, only the second side surface 22 'can be seen, because the first side surface 22 is concealed by the cheek area with the reinforcing area 24 and the corresponding tabs 23. In contrast, the two end faces 21, 21 'at least partially visible. At the end of each end face 21, 21 ', the flange 27, 27' is bent, each having the two screw holes 271, 271 '. Each of the side surfaces 22, 22 'is thus reinforced by the associated reinforcing region 24, 24' by means of the folding which has taken place on the second bending edge B, B '. Thus, part of the reinforcing area 24, 24 'is formed by the overlapping area of the tabs 23, 23'. The side surfaces 22, 22 'and the reinforcing regions 24, 24' protrude beyond the end of the end face 21 'with their bending edges corresponding to the second bending line B, B'.

The first end faces 21, 21 'are reinforced by joining with the second end faces 25, 25' of the other sheet metal part 2, 2 ', as it is also from the Fig. 3 shows, and thus form respectively the first and second front part. You could alternatively in the case of a one-piece frame, which is thus formed only of a single sheet metal part 1, also be formed by folding from a respective adjacent reinforcing surface 15, 15 ', as for example in Fig. 1 is shown. It could also be added to the end face as a separate component in one of the alternative embodiment, a reinforcing surface, wherein the flange would advantageously be angled perpendicularly from the reinforcing surface.

Thus, the first area B1, namely the base frame, for a number of reasons greater strength than the second area B2. The first region B1 has this strength on the one hand due to its closed shape, which is realized by the also large-area connections of the first and second end faces 21, 25 ', 21', 25 of the two sheet metal parts 2, 2 ', and on the other by the reinforcement this first area B1, which takes place at least partially by means of the second area B2, namely the overlapping area of the tabs 23, 23 '. In particular, therefore, in the distinction of the first area B1 and the second area B2 also to note their functionality. The base frame, ie the first region B1, is stabilized by the reinforcement region, and thus also by an overlapping region of the tabs 23, 23 ', that is to say also by a part of the second region B2, namely by its reinforcement regions 24, 24'. In particular, he sets according to its intended function, namely holding the modules 3, outwardly acting forces by this gain a particularly large force. In particular, this applies if the holding frame firmly mounted in a connector housing, for example screwed to four screw holes 271, 271 'in the connector housing, or otherwise fixed to its screw holes 271, 271'.

The second region B2 consists of the cheek area and comprises the unreinforced tabs 23, 23 'and thereby sets against a respect to the frame outwardly on the tabs 23, 23' acting force a much lower resistance moment contrary to the second area, namely the base frame. Thus, the second region B2 may have a much higher elasticity than the first region B1. In other words, the holding frame, for example, against a force acting from the inside against its second side surface 22 ', a much larger moment of resistance than against a force that presses against one of the tabs 23' from the inside. This can be explained, in particular, by the fact that against forces pressing against the side surfaces 22, 22 'from the inside, the resistance moment of the respective side surface 22, 22' and the moment of resistance of the reinforcement region 24, 24 'of the outer cheek area add up to a total resistance moment , This total resistance torque is thus of course greater than the moment of resistance of the respective individual side surface 22, 22 '.

The number of tabs 23, 23 ', namely eight in this case, is chosen as an example; the holding frame could for example also six, ten, twelve or fourteen or another even number of tabs 23, 23 'have. The half, namely in this case those four tabs 23, which are located on a first side of the holding frame, have larger, in particular longer, windows 231, than other four tabs 23 ', located on the other side of the Holding frame are and their windows 231 'comparatively smaller, in particular narrower than the first-mentioned windows 231 and accordingly have a different shape. In particular, the first locking lug 31 of the module 3, as shown in FIG Fig. 4a is shown by way of example, in the larger window 231 and the second locking lug 31 ', as in Fig. 4b is exemplified, in the smaller window 231 'insertable. As a result, the orientation of the respective module 3 is fixed in the holding frame.

The locking lugs 31, 31 'thus either fit positively into the respective latching windows 231, 231' or are at least so insertable that the modules 3 can be fixed by them in the holding frame.

Is exemplary in the Fig. 5 a module 3 is shown with a view of its cable connection side. the module 3 is locked in the holding frame by its locking lug 31 is received by the locking window 231. Furthermore, it can also be seen that the tabs 23, 23 'are slightly bent apart towards their free ends, which further facilitates the introduction of such a module 3.

The module 3 is thus kept particularly stable in its position by the particularly strong and stable first region B1, namely the base frame. Furthermore, the module is stabilized by the base frame protrudes in the region of its side surface 22, 22 'with its bending edge B over the end of the end face 21, 21' and thus in particular applies a strong leverage. The holding frame keeps the modules 3 at their long sides 32, 32 'over a large area.

Furthermore, the module 3 is thereby very easily operable in the tabs 23, 23 'locked, the tabs can be easily diverged due to their elasticity both for locking and for unlatching with little force. In particular, those tabs 23, 23 'which lock a module can be bent apart individually in order to unlock the individual module again independently of other modules and thus release it again.

Since the tabs 23, 23 'of the holding frame are slightly bent away from the holding frame at their free-standing end region, the modules 3 are particularly easy to insert into the holding frame. For this purpose, a module 3 is first inserted between two tabs 231, 231 'of the holding frame and then slides along with its two longitudinal sides 32, 32' and in particular with the locking lugs 31, 31 'integrally formed on the end regions of the tabs 231, 231' bent away from one another , As a result, the two tabs 231, 231 'briefly diverge until the respective latching lugs 31, 31' are received by the associated latching window 231, 231 'of the respective tabs 23, 23' and thus latched therein. When receiving the latching lugs 31, 31 'into the respective latching window 231, 231', the tabs 23, 23 'preferably spring back into their starting position. In this way, the modules 3 can be locked individually in the holding frame or removed. At the same time, the respective module 3 is held in the holding frame, in particular by the stable and fixed first region B1, namely the reinforced base frame, with great force. Thus, a very good ratio between holding force and operating force is achieved.
