Description

The invention relates, according to claim 1, a coaxial connector.

Coaxial connectors with axially displaceable or radially pivotable contact springs have long been known. Thus, in the connection element according to DE 40 27 407 A1 a longitudinally displaceable actuating piece is used to move a contact element against the force of a spring. This contact element is designed as a bridge contact and is applied to a contact spring, which is connected to a second inner conductor rail. About this arrangement, a connection between the second inner conductor rail and the first, which is directly connected to the contact element, produced or dissolvable.

The same principle is also used in the transition connector according to DE 41 30 914 A1, where there the bridge contact is used to short the two separate inner conductor of two coaxial cables.

Furthermore, in the connector unit according to DE 92 15 031.4U1 a contact pin is used which is longitudinally movable and consists of conductive material. During axial displacement, a bridge contact is opened or closed and at the same time establishes a connection to an antenna connection via the bridge contact spring.

Furthermore, from DE 43 27 986 C2 a coaxial connector with radially pivotable contact springs is known, wherein the complementary connector (i.e., the socket) has a same actuator as the connector (i.e., the connector) and a line terminating resistor is switchable

In order to design a coaxial connector under the cramped installation conditions in the automobile, which is inexpensive, can be miniaturized and convenient to assemble and handle, from DE 196 09 571 A1 a plug and a socket are known, which are locked together by a detent spring , This detent spring is mounted on the plug housing and preferably fixed in an annular groove which is located on the outside of the housing of the plug. This annular groove rotatably receives the detent spring about the axis of the plug but non-displaceably in the longitudinal direction of the axis and is located near the insulating support provided in the plug housing, at the transition from the rear part of the plug housing to the sleeve forming the front part of the plug housing. From this groove, at least one finger extends along the lateral surface of the sleeve. If the outer conductor of the socket receives the sleeve of the plug, then the fingers preferably extend along the lateral surface of the sleeve at most to the front end of the sleeve and abut with their projection of the sleeve. Then, when the plug is pushed into the outer conductor of the socket, the fingers are going through it lifted, slide along the outer conductor of the socket along and finally engage behind the designated locking means. However, if the sleeve of the plug on the outer conductor of the socket, then the fingers extend along the lateral surface of the sleeve along preferably beyond the front edge, wherein at the protruding end of the at least one finger directed against the axis of the connector projection is provided. When the plug is pushed onto the socket, the projections of the fingers move along the outside of the socket until they meet a cut or projection provided on the outside of the socket, in particular a collar; upon further pushing of the plug onto the socket, the fingers are bent radially outwards by sliding on the collar, and as soon as the projections of the fingers have overcome the collar, they spring radially inward and cause the locking. At the same time a contact pin is inserted into an inner conductor contact socket, which expands elastically in order to achieve a good electrical contact between the outer conductor of the sleeve and the sleeve, the sleeve should preferably be formed so that it can be elastically expanded, either by it is correspondingly thin-walled, either by being longitudinally slotted. Alternatively or additionally, a good end-side contact between the male outer conductor and the outer conductor of the socket can be achieved in that the projections latching behind the collar not only have chamfers on one side, but on the other side have drain slopes, with which they at Snap the connector outer conductor against a stop formed on the socket.

Furthermore, from DE 199 26 473 A1 a coaxial interface is known in which an electrical and / or mechanical adjusting or switching device is provided. This is designed such that - at least when the connector plug device removed - the outer end of the outer conductor with sufficient axial distance projects beyond the outer end of the electrically active inner conductor to produce a waveguide attenuation. This creates a possibility for coaxial interfaces to improve the degree of shielding and the electromagnetic compatibility, in particular of open RF connection points. It is often sufficient that with such an open interface, the outer conductor protrudes in the direction of connection more than 3 to 5 mm beyond the end of the inner conductor. In an alternative embodiment, the inner conductor is designed as a separate axially adjustable inner conductor piece, which cooperates for example with an internal contact spring. When pulling off a coaxial connection cable, the separate inner conductor piece is then adjusted axially by a spring device by the spring action so that the internal electromechanical connection to the contact spring is released. This has the consequence that the last component connected to the inner conductor of the house wiring consists of the contact spring, which ends much further inside the outer end of the outer conductor. As a result, a high attenuation is also achieved.

From EP 0 447 660 A1 a connection device for data transmission lines, in particular for a data network, with at least one plug-in device with plug contacts is known in which a socket and a plug cooperate. In order to provide a connection device for data transmission lines, which works very reliable and interference-proof and optimally adapted to the network and the connection devices with a small size, one of the plug contacts during mating of the plug in this device is arranged axially movable and provided with an actuated by axial movement switching contact. Thus, the separation of the example along a wall guided Data bus to be accomplished when inserting a connector, and when you solve this plug, the line closes again and can thus supply the other devices. Between plug and socket a preferably designed as a screw or bayonet lock positive locking device is provided. Furthermore, a terminating resistor which is automatically switched on when disconnecting the plug connection can be provided in the plug-in device. This can be switched in the same way by an axially displaceable central sleeve without occupy any additional space by the switch contact a provided on the plug contact contact shoulder, preferably in the form of an annular surface of an attached to an inner contact flange-like ring containing at a mating contact surface under the Effect of the inner contact axially against the insertion direction loading spring is pressed. The forward and return line can be connected within a shield characterized in that the manner of a BNC coaxial connector with an inner contact and a contrast shielded external contact connector formed a surrounding the inner contact, separated by an insulation intermediate contact. A total of three-pole coaxial connector makes no significant manufacturing overhead and allows the connection in particular of terminals on data networks, but is also for other uses, such as stereo connections, separate video and audio or other connections with two shielded conductors, useful. Another embodiment connects such a 2-inner conductor connector with two conventional connectors, such as BNC connectors, in T-shape to a terminal unit, in which the data bus is connected on both sides via conventional BNC connections and the connection lines can be connected with automatic switching.

Several of these tees can be connected directly by plugging together and combined into complete power strips.

A miniature plug-in coupling, for use in telecommunications equipment, in particular for attachment to a printed circuit board, which serves as a wiring backplane, for example, in a rack, said plug and socket each having a metal housing with a coaxial contact secured therein electrically and the metal housing of the Socket part and its coaxial contact each have a pin, is known from EP 0 341 535 A2. On the one hand to allow a connection with a coaxial cable and on the other hand connections with two contact elements of the female connector of a conventional assembly, the pins are designed as straight, extending in the plug direction plug pins, of which the metal housing is fixed in a laterally projecting tab of the metal housing. The two pins have immediately behind the metal housing depending on a press-in zone, with which they can be fastened in holes in the circuit board. The metal housing of the female part has a constriction above the holding part, in which, when the connection is made, a constriction of the male part that engages over the female part is latched. A front sleeve part of the metal housing of the plug part has at least one slot extending in the axial direction and the constriction forms in the sleeve part a bead, in which a spring ring is inserted. When the connection is made, the front edge of the metal housing of the socket part engages in an annular groove of the metal housing of the plug part.

Another snap closure for coaxial connectors with a sleeve, fingers and this encompassing annular spring, which generates a corresponding radial force component is known from US 32 06 540 A1.

A socket for signal-transmitting connection with a pin having a plug, wherein the socket has a housing socket on which a conductor can be attached, is known from DE 42 03 945 C1. In order to separate the function of the power transmission from that of the production of the electrically conductive connection, it is provided that the signal-transmitting contact surface formed between the socket and the plug is formed outside the surface of the pin. A provided on the socket housing socket has in the interior an axially displaceable 'piece-shaped bush socket socket, between which one end face and a plug to be connected to the socket, the contact surface is formed. The contact surface formed between the front side of the socket holder and the plug is arranged perpendicular to a pin provided on the plug. In this case, the socket holder against the force of a graded in the housing socket spring, in particular a helical compression spring, displaced. In the socket holder, a sleeve may be arranged, which rests with its outer circumference on the inner circumference of the socket holder and which may have at least one slot along its surface line. The sleeve and the socket socket have a flush termination on their common end face. Furthermore, a radially inwardly extending projection is provided on the, the plug facing the end of the housing socket, which is engageable with a on the outer circumference of the socket holder radially outwardly extending projection. As a result, the axially displaceable socket socket can not slide out of the housing socket. Finally, it is provided that the pin of the plug into the sleeve of the socket holder against the spring pressure can be inserted, and to the extent that the end face of the socket holder comes to rest with the end face of the plug to form the contact surface. On the one hand, good signal transmission, in particular in the high-frequency range, but also in the DC range, can be achieved by this arrangement. On the other hand, a mechanical damage of the pin is excluded by abrasion.

A plug-in device for coaxial cable, in particular BNC plug, for attachment to a counterpart provided externally with holding forms, such as the above pins, for example a BNC socket, is known from DE 198 51 725 C1. To form radially resilient spring fingers is a multi-slotted in the longitudinal direction, circular cylindrical sleeve comprises an axially displaceable outer sleeve. The resilient fingers have on the inside to form a circumferential locking ring locking lugs for locking with the holding forms of the counterpart. In order to specify a connector which is suitable for connection to a provided with externally projecting holding molds counterpart, wherein the connection is quickly closable and separable and which does not dissolve in the closed state by pulling the cable, the outer sleeve at the front has a circumferential, the Finger over the edge, wherein the inside of the peripheral edge and the fingers are formed such that the fingers are pressed when retracting the outer sleeve to release the locking connection from the edge to the outside. For this purpose, the front side of the fingers and arranged at the front end of the outer sleeve, the fingers across edge chamfers. Due to the chamfers and given by the peripheral edge constriction of the outer sleeve a simple, centered insertion of the counterpart provided with retaining pin is possible. They are pressed outwards and finally lock with the retaining pins. When retiring the Outer sleeve, the fingers are pressed against the tension of the annular spring to the outside, so that the retaining pins are released. The connector can therefore be unlocked and released by simply pulling on the outer sleeve and can not be solved by a train on the cable in the closed state. With appropriate design of the locking lugs, the connector can also be used with couplers, on the outside of a locking groove or similar latching forms are incorporated. To strengthen the closing action of the resilient fingers can be provided that the fingers are tensioned by an externally mounted spring ring.

In order to provide an antenna adapter that is compact and easy to attach to the base unit, it is provided that the adapter includes an integrated antenna and the switch is designed as a switch between the integrated and external antenna. The switch can be actuated by an axially preferably freely movable center pin of the coaxial - connection socket. So he needs no own return spring, but is of the self-resilient movable switch contact, which may be integrally formed with the central conductor pin of the adapter, both pushed back into its initial position and brought into contact pressure with the antenna contact. In the connected state of the connector snap latches one behind the other and prevent plug and socket are pressed apart.

A switchable coaxial connector is known from US 5,921,793 A1. With the insertion of the coaxial connector pushes a sliding insulating member against a spring loaded with a ring flange and lifts the ground contact to the terminating resistor. As soon as the plug is removed again, the insulating part and thus the annular flange returns to the starting position as a result of the spring, whereby the ground contact to the terminating resistor is restored.

Furthermore, from DE-G89 12 821.4 a coaxial angle plug for connecting a vehicle antenna cable to a vehicle radio receiver is known in which the pin via a conductor of a printed circuit board arranged in angled connector and a switched into the conductor chip capacitor with the inner conductor of the Antenna cable is connected and the circuit board has a connector pin area comprehensive the connector pin and a projecting from this narrow cable connection area. In order to reduce the dimensions in the simplest and most cost-effective manner and to ensure a permanently reliable function of the chip capacitor even when voltages occur in the cable connection region, the chip capacitor is arranged in the plug connection region of the printed circuit board. To ensure that the pin remains coaxial even when not exactly axial insertion or withdrawal in or out of the receiving socket, the pin is at least partially tubular and mounted with the open end portion in a recess of the circuit board, wherein a relative to Printed circuit board shelf stable arranged pin protrudes into the pin. The plug connection region of the printed circuit board is fixed between a base plate and a cover plate and is arranged in a stable position in the plug housing, and the journal is an integral part of the base plate.

In detail, the plastic housing consists of a substantially plate-shaped housing part with molded cable connection housing part and sleeve and a lid. In order to realize the pushing back of the plug when the mechanical connection is not closed, the bushing has a spiral spring, which is compressed by one of two contact sleeves of the plug during insertion until the sleeve of the plastic housing of the plug is seated in the circumferential annular groove of the cylindrical plastic tube of the plug , Such a plastic latching connection between a plastic housing and a cylindrical tube mounted in the metallic housing of the sleeve, is obviously not suitable for the repeated opening and closing of the connector.

As the foregoing discussion of the prior art demonstrates, various coaxial connectors, with or without a switching function, are known for various applications and configurations. The main disadvantage of the above-described prior art is that the manual production of the connector requires increased care, especially if a switching function is triggered, which is why cost-effective coaxial connectors missing in practice, which allow inexperienced users safe operation. This is particularly important because both the entertainment, computing and telecommunications industries are considered to be extremely advanced, development-friendly industries that are quick to pick up on improvements and simplifications and put them into action.

A further advantage is that the spring encompassing the spring compensated for tolerances. As a result, the insertion process is subject to no restrictions and is also independent of whether the sleeve of the plug is inserted obliquely against the coaxial axis or not. A mechanical stress only occurs on the movably spring-loaded plug socket, specifically in the area inside the sleeve, so that it also provides protection against contamination and environmental influences. In addition, a significant reduction in the required insertion and removal forces is possible, resulting in an increase in the number of possible mating cycles.

The FIG. 1 shows a preferred embodiment of the coaxial plug connection according to the invention, wherein the electrical contact input between an outer conductor of a socket B designed as a socket housing B and a sleeve H of a plug S and between an inner conductor contact socket I forming the inner conductor of the plug S and a contact pin inserted in the latter K takes place. In principle, the inventive concept is suitable for many applications, with the field of application ranging from satellite reception technology and terrestrial reception to systems of data and telecommunications technology.

According to the invention, the sleeve H has on the inner side a fillet A (either a bulge or a cavity) which is configured such that sleeve H and bush B audibly engage with each other when plugged together, since the fillet A inevitably fits into a receptacle KA (FIG. either a cavity or a chamfer or bulge) of the socket B and thereby against the first stop AS1 forming end side of recording KA and / or B is pulled, as well as the FIG. 2 to FIG. 5b show.

The inner conductor contact socket I can be configured as a hollow body HL guided in an insulating body IK, spring-loaded and on the side facing the contact pin K. The sleeve H is preferably slit longitudinally at least in subregions Z1 to Z6, wherein at least on a so-formed resilient portion Z1 to Z6 a first compression spring RF is present. Fillet A and receptacle KA are designed such that sleeve H and socket B audibly lock together when plugged together, at least one switching contact RI, AS of the inner conductor contact socket I is actuated. In particular, the fillet A of the sleeve H is designed as a circumferential chamfer / bulge and on the outside of the sleeve H at least one concentric around the contact pin K extending recess AN for a slotted annular spring RF (first compression spring) is arranged. The socket housing BG is designed on the plug side as a collar BU with a slope SC and the sleeve H as axially extending resilient tongues Z1 to Z6, on which slide the tongues Z 1 to Z6 against the spring force of the annular spring RF during mating and widen these'radial until the fillet A of the plug S is seated in the receptacle KA of the bush B between the collar BÜ and the end face of the bush housing BG. In this case, the fillet A or the receptacle KA can be provided with a drainage slope in order to increase the impact force or to improve the inevitability when plugging in and pulling (drainage slope is equal to bevel). The width of the chamfer A and the corresponding throat KA (rounding A or recording KA) determines the axial play in the inserted state and also whether rounding A and / or end face of the plug S abuts against the respective end face / recording of the socket B.

As in particular FIG. 1, the hollow body HL is constructed in two parts from a pin sleeve HL 1 and a resilient contact pin HL 2 guided therein. Between the opposite ends of the pin sleeve HL 1 and pin HL 2, a second compression spring DF is arranged. The contact pin HL 2 as part of the switching contact RI, AS2 has an annular flange RI, which by means of second compression spring DF against a stop AS2 of the Socket housing BG is pressed. Above the annular flange RI, the contact pin HL 2 is designed to be hollow and longitudinally slotted.

According to FIG. 2 and FIG. 5a and 5b, the plug S can be designed as an angle plug, which when mated at least one arranged in the socket B terminating resistor, for example, 75Ω, operated. In this application, the female housing BG can be stored by means of screw or snap connection SV in an antenna socket:

Compared to the known prior art, the coaxial connector according to the invention allows positive centering and easy adjustment of the impact force during insertion, reliably prevents the supply of interference, is partially compatible with normal BNC Steckein and also allows rapid and reliable operation including the switching function. The key advantage is that the click is easy to hear when making electrical contact, since the plug or the socket in this area are designed as a hollow body and accordingly act as a (metallic) sound body. The sound effect is largely independent of whether the rounding A is designed as a bulge or as a hollow and hardly diminishes without ring spring.

All illustrated and described embodiments, as well as all disclosed in the description and / or the drawings new individual features and their combination with each other, are essential to the invention. For example, both the socket housing and the sleeve as axially extending resilient tongues (wherein the inner sides or outer sides of the tongues each have a fillet or carrying a corresponding receptacle) are configured, wherein an annular spring can also be omitted; the female housing can also be designed lying inside with a circumferential collection / chamfer, the female housing, the sleeve inserted therein, which has a circumferential and latching in the collection recess / receptacle surrounds; it can axially displaceable or radially pivotable contact springs of the switch contacts are provided, instead of a screw connection between the plug body and the holder, this can also be pressed, inter alia
