Description

Connector with sliding guide for connection with a connector socket.

The present invention relates to a connector for connection with a connector socket, which has a connector bushing housing with a first longitudinal axis and with an accommodation space surrounded by a wall, which is open towards a front surface of the bushing housing connector and closed by a floor at the far end of it and to which first contacts are assigned, being arranged in stand out on an outer surface of the wall surrounding the space housing at least one retention overhang, which it has a stop surface that rises away from the outer surface in the direction of the front surface at ground and that in the direction towards the ground is endowed with a retention surface that runs in the direction of the outer surface, comprising a connector housing, which it has a second longitudinal axis, which presents a first housing section with a first axial terminal surface that, when the longitudinal axes are oriented parallel to each other, You can enter the accommodation space, which has a second housing section with a second terminal surface away from the first terminal surface, on which it is formed an elastically adjustable pin with a retention rib, the retention nerve facing the abutment surface of the retention boss, during connection with the housing connector bushing, and projection retaining surface retention, in the fully connected state of the connector with the connector bushing, a sliding guide, which surrounds, so less partially, the connector housing and that is arranged adjustable on it along the second longitudinal axis between a first position and a second position, the first corresponding position to an unlocked position of the bushing housing connector with respect to the connector and the second position to the position completely connected to them, which carries a lever elastically adjustable security, which features a protrusion of security, which is in the first position, in direction towards the first axial terminal surface, in front of the retention nerve and in the second position, towards the first axial terminal surface, behind the nerve of retention.

Document DE 102 16 072 A1 describes a connector for the connection of a connector socket. Understands a connector housing with a second longitudinal axis. This one you can enter, when the longitudinal axes of the connector and the connector bushing are oriented parallel to each other, in the accommodation space of the connector sleeve with a first housing section with a first axial terminal surface. The housing has a second terminal surface away from the First terminal surface. To the connector housing is assigned A pin with two arms. It presents, in the direction of first terminal surface, a retention nerve and, moving away of the first terminal surface, behind the retention nerve, a grip. Approximately through the center the pin It is rotatably connected to the connector housing. Is driven out, away from the first terminal surface, in direction to the second terminal surface, through the connection with the connector housing and forms a second arm of lever, which features release drive sections for pin drive. It is pressed in such a way on the release drive sections that the second arm of pin lever approaches the outer surface of the connector housing At the same time the retention nerve is moved upwards away from the outer surface of the Case. When connecting the connector housing with the housing connector socket, the surface retention nerve of stopper of the retaining boss of the bushing housing connector is opposite and, when insertion is continued, it is lifted and placed behind the retention boss. The connector it also includes a sliding guide, which surrounds at least partially the connector housing and which is arranged along of the second longitudinal axis adjustable in it between two positions, the first position corresponding to a position not interlocked in the connector sleeve housing with respect to the connector and representing the second position the position completely connected to them, that is, when the nerve pin retention has been placed behind the projection of retention. The sliding guide has a safety lever of a only elastically adjustable arm, which has a projection of security which, in the first position, towards the first axial terminal surface, is in front of the nerve of retention in the draft and in the second position, in the direction towards the first axial terminal surface, it is located behind the retention nerve In this position the sliding guide is held by the safety lever, actuated by friction, in the retention nerve in the locked position. To release the been locked in the final position, the sliding guide must be moved back again, the clamping force being defeated generated by the safety lever and being able to access the guide sliding with its safety protrusion behind the nerve of retention. At the same time the safety nerve, which prevents a turning movement of the pin, is moved away from the second pin arm, so that, through the sections of release drive that are exposed in a section of the sliding guide, the retention rib can be raised out of the crimp with the retention boss. Then the connector and the Connector socket can be separated from each other.

EP 0 896 396 A2 describes a plug-in connector which comprises a connector socket and a connector The connector sleeve has a housing connector socket and a housing space surrounded by a wall. This is open towards a front surface of the housing of connector sleeve and is closed by a floor by its far away from her. The connector sleeve has a first  longitudinal axis, which defines a connection direction. To connector socket housing are assigned first contacts These are oriented parallel to the first longitudinal axis and protrude from the floor into the space of accommodation. On the outer surface of the wall surrounding the accommodation space are arranged in protruding a projection of retention and two nerves that runs parallel laterally with respect of the same.

The connector features a connector housing with a first housing section and a second housing section. The first housing section enters, during connection with the connector socket, in its housing space. The second housing section is arranged at a radial distance from the first housing section, so that between them there is a free space, which houses the wall of the bushing housing of connector To the second housing section of the connector is assigned an elastically adjustable locking arm, which can be interlocked by a spring clip, when found in the closed position, preventing the spring clip from orientation of the closing arm out of the unloaded position.

About the spring clip are assigned compression springs which are connected to each other, in the end that does not rest on it, by means of a crossbar. The arm of closure has an inclined surface which, during connector insertion, runs on the connector socket against the retention boss. At the same time the bra of springs are in a forward position, in which its closing surface with is in contact with the arm of closing. It is held in this position in the connector housing by elastic arms with retention projections.

With this type of plugged in connection it is generated a force of liberation which displaces the two away components of the plugged in connection, that is the socket of connector and connector, while the status of definitive connection, in which both are embedded one respect of the other. The constructive measures planned for this require a large building space which is not frequently especially available in case of narrow conditions and in case of arrangement of a large number of connectors in an appliance or in an accessory of a motor vehicle. Despite this it is desirable let it be recognized at least if it has been achieved or not A complete connection.

The present invention poses the problem of propose a connector for connection with a connector socket which is suitable for narrow mounting conditions and that present a sliding guide, which allows to recognize if achieved or not a complete connection, not being able to move the involuntary sliding guide of the position corresponding to The complete connection.

This problem is solved according to the invention. through a connector which is characterized in that the lever safety is structured as a two-arm lever, which it presents a first safety arm with a safety protrusion, which in the first position, in the direction of the first axial terminal surface, is located in front of the nerve of retention and in the second position, towards the first axial terminal surface, lies behind the nerve of retention and presenting a second safety arm, which It can be loaded by hand for safety shoulder movement out of the crimp with the retention nerve.

In this structuring it is advantageous that, based on the position of the sliding guide, it can be recognized whether or not a completely connected state has been reached. The sliding guide is securely held in the corresponding positions that characterize the unconnected or not yet fully connected state and the fully connected state. In the first position, the sliding guide is displaced so far from the first terminal surface that the safety protrusion of the safety lever is, towards the first terminal surface of the connector housing, in front of the retaining rib and the retention nerve prevents the sliding guide can be moved to the forward position that characterizes the completely connected state, in which the safety shoulder, starting from the first position, is in a position behind the retention nerve, in which the safety projection, starting from the first position, is in a position behind the retention nerve. The safety shoulder runs behind the retaining rib during connection of the connector with the connector sleeve. First, the retention rib is raised by the retention boss of the connector bushing, that is, it moves away from the outer surface thereof, running upwardly over the abutment surface. The following safety projection also runs, after the retention rib, on the abutment surface and is raised, so that the safety lever rotates. After the retention nerve has reached the end of the retention boss, the retention nerve again adopts, due to the elasticity of the pin arrangement, its original position and is placed behind the retention boss and is located at same time in direct vicinity with respect to the retention surface of the retention boss. Continuing the forward movement of the sliding guide the safety shoulder passes beyond the retention projection and the retention rib, which cannot continue moving forward in the direction towards the first terminal surface, and is located behind the rib of
retention.

According to one embodiment, it is provided that the pin is formed as a two-arm lever, which has a first arm and a second arm, serving the second arm for actuation of the pin, and that the second arm of safety load the second arm of the pin, so that it can move out of the crimp with the retention boss. Preferably, it is provided that the pin comprises two identical parallel pin sections, whose first arms are connected to each other by the retention nerve, and that the safety lever is arranged between the two sections of parallel pin.

For the case in which a pin of two is chosen arms is provided that the safety lever has two release inserts on your second safety arm, which in each case they are used to load one of the second arms of the pin to, in the fully connected state, be able to carry the retention nerve outside the crimp with the projection of retention.

In a second solution variant, for the pin retention nerve movement outside crimp with the retention boss, it is provided that the sliding guide present at least one release heel which, in case of a movement of the sliding guide in one direction away from the first final surface, move the first arm of the pin with its retention nerve outside the crimp with the retention boss. In this case it is possible to form the pin as an arm lever, at least one release heel acting on the first arm. For the case where the pin is structured as a lever with two arms, it is also possible to arrange the release heel in such a way in the sliding guide acting on the second arm.  In both cases the release heels are arranged in such a way. so first of all, by acting on the second arm of safety of the safety lever, the projection is moved first safety outside the crimp with the retention nerve and then, when acting continuing stretching on the guide Sliding, release heels act and carry the pin with your retention nerve outside the crimp with the projection of retention. At the same time it is possible to load the second arm of the hand pin or choose a structuring in which this is loaded by the sliding guide, by movement of the guide sliding away in the direction of the first terminal surface of the connector housing.

Preferably the pin is connected in a single piece with the connector housing through a rib of closure, which forms a pivot axis of the pin. The pin rotates so both around the axis of rotation formed by the nerve of closing.

The safety lever can be connected also of a piece with an inner surface of the guide Sliding through a lever nerve, which forms an axis of turn.

For hand drive of the second arm safety of the safety lever is provided a recess  in the sliding guide housing.

The connector housing is also equipped with less with a stop, which thereby limits axial movement of the sliding guide on the connector housing that it cannot slide down the connector housing. In position no connected to the connector, that is for example during transport or before assembly, the sliding guide is fixed in position, by one side, through this stop, which interacts with the housing of connector and, on the other, by means of a safety highlight of the safety lever, which sits in front of the nerve of retention.

In the first place it is described, from the Figures 1 and 2, the structure of the connector sleeve 1 itself known and of connector 13 according to the invention.

The connector bushing 1 comprises a housing of connector sleeve 2 which can be connected so fixed, for example, with an electrical appliance, that is to say component of the same. It is made of a resin material (plastic) electrically insulating and has a first longitudinal axis 3. The connector bushing housing 2 further comprises a wall 4, the which surrounds a housing space 5, which is closed by the floor 7 and that at its open end is limited by the surface front 6. Wall 4 forms an outer surface 8. Space of housing 5 forms a rounded rectangle at ends Opposites, although you can present any discretionary form. From one of the sections of the outer surface 8 protrudes the retention projection 9, which has towards the front surface 6 a stop surface 10, which runs ascending, away from the front surface 6 towards the ground 7, and that at same time it moves away from the outer surface 8. It ends in a tip or a surface that runs parallel with respect to the outer surface 8 and is transformed from there into a surface of retention 11, which runs again steep in direction with respect to the outer surface 8.

In Figure 1, a connector 12, whose connector housing 13 is made of a electrically insulating and plastic resin material elastic properties and that is centered on the second axis longitudinal 14. Connector 12 is shown opposite the connector socket 1 but not yet connected, being oriented towards each other the first longitudinal axis 3 and the second longitudinal axis 14. By displacement of connector 12 towards connector socket 1, with longitudinal axes 3, 14 oriented towards each other, the bushing is connected to each other of connector 1 and connector 12. The bushing housing 13 it comprises a first housing section 15, which during the connection enters the accommodation space 5 of the bushing connector 1. This has a first terminal surface 16. The connector housing 13 further comprises a second section of housing 17, which ends at the second terminal surface 18. In the connector housing 13 two housing chambers are formed 19, which are used to accommodate contact bushings K. These are fixed by formed tabs and also by a fastener 20 in the connector housing 13. The bushings of K contact are connected, for example, with wires and are used to, during connection of connector 12 with connector socket 1, accommodate the first contacts, in the form of pin contacts 9, protruding from the floor 7 in the accommodation space 5 of the connector socket 1, in order to establish a connection electrically conductive The second housing section 17 has an outer surface 21 which, towards the first housing section 15, is limited by the provision of shutter 22, which interacts with the inner surface of the wall 4 in the plugged-in state of the connector socket 1 and of connector 12, in order to seal the unit against moisture or incoming dirt.

From the outer surface 21 of the second housing section 17 protrudes near the second surface terminal 18 at least one stop 23.

In the second housing section 17 is formed a pin 24, which comprises a first pin section 25 and a second pin section 26. The pin 24 is structured globally as an arm lever, forming both sections of pin 25, 26 in each case a first arm 27, which is connected in one piece with the second housing section 17 by means of a closing rib 30. The first two arms 27 are extend, starting from the closing nerve 30, approximately parallel but distant from the outer surface of the connector housing 13, towards the first terminal surface 16, although not completely to the surface terminal 16 but only along a partial zone of so that the retention nerve 28 that connects the first two arms 27 is located above the first housing section 15. The two pin sections 25, 26 are arranged remotely parallel and run approximately parallel to the second longitudinal axis 14 and form a free space with each other, the which is bridged by the retention nerve 28. In addition, the two first arms 27 have, as a prolongation of the nerve of retention 28 although in relation to it displaced in height of the outer surface of the connector housing 13, in each case a insert 29. The pin 24 can be elastically oriented, the closing nerve 30, around an axis, which crosses at an angle straight the second longitudinal axis 14 at a distance. Adopts however in the normal position, that is to say in the unloaded position, the position represented in Figures 1 and 2.

The connector housing 13 is surrounded by a sliding guide 31 in the form of a tube. It has an outer wall  32 and a guide section 33, in which there is a drill of guide 34, with which the sliding guide 31 is arranged, scrollable in a limited way along the second axis longitudinal 14, on the outer surface 21 of the second housing section 17. In the direction away from the first terminal surface 16 the movement of the sliding guide 31 is limited by at least one stop 23, which engages in a groove 36 and that, for the limitation of movement, interacts with a stop 37 located at the end of slot 36 of guide section 33.

With the outer wall 32 of the sliding guide 31 is located inside it, connected in one piece a safety lever 38 through a rotatable lever nerve 39 around an axis of rotation, which crosses the second longitudinal axis 14 at a right angle at a distance. The possibility of turning is possible thanks to the elastic properties of the material with which it is manufactured the sliding guide (resin material). The lever of Safety 38 is structured as a two-arm lever. The first safety arm, extending from the lever nerve 39 towards the first terminal surface 16, it is designated through 40 it carries a safety protrusion 41 that stands out in inward direction on the outer surface of the housing of connector 13. This is arranged at a distance from the nerve lever 39. On the second safety arm 42, which extends from the lever nerve 39 in the direction of the second terminal surface 18 of the connector housing 13, is formed a drive insert 43, which is located in a recess 35 of the sliding guide 31 and which can be loaded to hand. In case of loading of the drive insert 43 in the direction towards the connector housing 13 the safety lever 38 rotates, to cause of the elastic properties of the material with which it is manufactured the connector housing 13, around the axis of rotation formed by the lever nerve 39. In the unconnected state of the connector 12 and socket 1, the safety shoulder 41 is, seen in the longitudinal direction towards the first  terminal surface 16, before the retention rib 28. With this the sliding guide 31 is fixed, by means of the safety shoulder 41 and stops 23 and 37 that interact, in the positions that reproduce the unconnected state. Safety lever 38 is is in this position in its normal position, that is its unloaded position, which it adopts by elastic recoil in the lever nerve area 39. Sliding guide 31 also has release heels 44, which in each case engage on a insert 29 of one of the two pin sections 25, 26 of the first arms 27, when the sliding guide 31 is displaced from return from the state connected to the represented state.

From Figures 3 to 5 a description of the connection process based on the position according to Figure 1.

As can be recognized in Figure 3, the first housing section 15 of the connector housing 13 enters the accommodation space 5 of the connector sleeve 1. At the same time the retention rib 28 of the pin 24 approaches the stop surface 10 of retaining boss 9. This state is represented in Figure 3. Continuing with the introduction of connector 12 with its first housing section 15 in the bushing connector 1, retaining rib 28 slides over the surface of stop 10, deforming the closing rib 30 elastically and generating a recoil force. Continuing the introduction on retention nerve 28 passes over retention projection 9 and can be placed in front of the retention surface 11, thanks to move back back to its starting position. During this Forward movement of safety boss 41, which follows the retention nerve 28 in the direction of movement, has been moved on the abutment surface 10 of the retention boss 9, so that the lever nerve 39 elastically deforms and generates a recoil force, thanks to the lever security 38 rotates, in the sense that turns left, around of the axis of rotation formed by the lever nerve 39. This position elevated is shown in Figure 4. Continuing the movement of Advance of the sliding guide 31, safety boss 41 arrives beyond retention nerve 28 and placed, in the direction of movement towards the terminal surface 16 of the housing connector, behind retaining rib 28. This position is represented in Figure 5 and characterizes the state completely connected from connector 12 and connector socket 1. This Status can be determined by observation. To release the connection is pulled, on the one hand, of the sliding guide 31, so it moves away from the first terminal surface 16 along the second longitudinal axis and, on the other, at the same time it is pressed on the drive section 43, so that the protrusion of security 41 be elevated from the active connection with the nerve of retention 28. Sliding guide 31 can then slide from turn, since the first raised safety arm 40 allows that the safety projection 41 passes the retention rib 28 and the retention projection 9. Continuing the pulling action the retention nerve 28 is elevated, because the inserts 28 are raised in such a way by the release heels 44 that move away from the outer surface 8 of the connector sleeve 1, being able to access the retention nerve 28 beyond the heels of retention 9. As soon as retention nerve 28 has passed the heel 9, the safety shoulder 41 can move from back again, with guide back from pin 24, to position starting, that is the position that is represented in the Figure one.

Figure 6 shows a structuring Alternative for the pin. In Figure 6 you can recognize a explosion representation of connector 112 with the housing connector 113 and sliding guide 131. In relation to the housing of connector 113 it can be recognized that it is also formed by a first housing section 115 and a second housing section 117, finishing the first housing section on the first surface  terminal 116. The connector housing 113 is also formed a pin 124 which however, unlike in the form of embodiment according to Figures 1 to 5, is structured as a lever of two arms. Two pin sections are also provided. 125, 126 with in each case in first arm 127, both arms being 127 connected to each other by the retention rib 128. About the closing rib 30, through which the pin 124 is connected with the connector housing 113, two arms extend 45. These second arms 45 extend, from the nerve of closure 130, in one direction away from the first surface terminal 116. Sliding guide 131 has a lever security 138, structured in correspondence with the form of embodiment according to Figures 1 to 5, although it differs from it essentially just because in the second safety arm 142 are formed, laterally, release inserts 46 which, in case of loading of the second safety arm 142 in the direction release, act on the second arms 45 of the pin 124 and raise the retention rib 128 out of the active connection with the retention boss of the connector sleeve.
