Abstract: In order to simplify mounting and cabling of optoelectronic plug connectors (3, 3?) and—equipped therewith—subdistribution units (6) and subdistribution systems, the use of special module housings (100) is proposed. The latter can accommodate a plurality of, in particular eight, identical and/or different optoelectronic transducers (2, 2?) and are installed in the plug connectors (3, 3?) between the electrical plug contacts (311) and the multi-core optical cables (58), i.e. the cores (51) thereof. Susceptibility to errors is considerably improved as a result and mounting is significantly simplified as a result of the improved clarity.

Abstract: A board-edge plug connector establishes an electrical connection between at least one electrical conductor and at least one printed circuit board. The board-edge plug connector has a housing which accommodates at least one contact element and has at least one cavity which receives both the conductor and also the printed circuit board at least partially in the housing. The contact element both encloses and makes contact with the printed circuit board in a spring-elastic manner and also clamps the conductor against the housing and makes contact with it in a spring-elastic manner.

Abstract: A contact element for establishing electrical contact between a first and a second printed circuit board is provided. The contact element has a fastening region for fastening to the first printed circuit board and a plug section for a plug connection to the second printed circuit board. The plug section has at least two contact arms which are electrically conductively connected to one another. A method for assembling a printed circuit board arrangement is also provided.

Abstract: An unlocking aid for simplifying a process of releasing an electrical connector from a mating electrical connector is disclosed. The electrical connector comprises at least one locking mechanism, at least one housing element and at least one cable connection. The unlocking aid is brought into engagement with the locking mechanism of the electrical connector from outside the electrical connector and, by means of a connecting element, leads a gripping region to a position substantially behind the cable connection in order to release the locking mechanism.

Abstract: On a round plug, outwardly directed detent hooks are arranged between a plug-in region and a contact carrier portion of an insulating body or a base portion of the round plug housing. A mating connector has, on a plug-in side of a threaded portion, an inwardly directed circumferential or interrupted detent lug. The detent arms do not need to reach through the threaded portion. The detent arms can therefore be made particularly strong, and the inner thread can be continuous. The retaining forces of the locking/screwing are thus very high, and the detent arms for example can be integrally molded on a plastic insulation body, and thus be formed in one piece therewith, for simplified production. Operation and manufacture are significantly simplified.

Abstract: A plug connector to which a cable having at least one insulated conductor can be connected is provided, wherein the plug connector has a conductive rubber element with at least one conductive layer, but preferably with at least two conductive layers. The electrical connection of the conductors is realized by the conductive rubber element. The conductive rubber element can also form the plug face of the plug connector. As an alternative, the conductors can be connected to contact elements by the conductive rubber element.

Abstract: A plug connector, in particular a modular plug connector, is provided for mounting on a circuit board. The plug connector can be assembled from a plurality of plug connector modules, wherein each plug connector module comprises at least one part. The plug connector modules have an insertion side and a connection side, wherein the insertion side can either be installed on the circuit board or else it contacts a connection side of a mating connector module. The plug connector modules can be connected by at least one connector. This makes it possible also to install modular plug connectors on a printed circuit board.

Abstract: A shield element (1) of a printed circuit board connector enables maximum tolerance compensation between a printed circuit board (5), on which the printed circuit board connector is secured on the connection side, and a housing wall (4) of a device housing surrounding the printed circuit board (5). The shield element (1) is substantially hollow-cylindrical and can be fitted onto the insulating body (2) on the insertion side so as to also ensure a required connection to ground over the large desired tolerance range.

Abstract: A plug-type connector for connecting a cable with at least one wire to a respective plug contact includes a first housing part, a connection block and a second housing part. A hinge connection allows the second housing part to pivot out of a first position into a second position towards the first housing part. In the first position the wire can be inserted into a wire channel of the connection block and, in the second position, the second housing part presses the connection block against the insulation displacement contact. The second housing part can move into a third position in which the connection block is fully pressed onto the insulation displacement contact. The hinge connection allows an insertion movement from the second into the third position such that the second housing part inserts the wire into the insulation displacement contact in an exclusively translatory manner.

Abstract: A compact design for a push-pull latching system for a rectangular plug includes at least one locking and releasing element (11) which is held against a broad side of a plug housing in such a way that the locking and releasing element can be moved parallel to the broad side of the plug housing (1). The locking and releasing element (11) can be formed integrally with the plug housing (1) from an elastic plastic and can have a plurality of locking arms (111) having locking hooks (113). The movement necessary for releasing is then inversely proportional to the number of locking arms (111); the elasticity is also determined by the shape of the locking arms, in particular the width of the locking arms.

Abstract: A plug housing comprises at least one leaf spring element in a cable duct, which has a central part and a respective first and second lateral part which are bent in relation to said central part. The first lateral part is elastically bent via a first bending edge and the second lateral part is elastically bent via an opposing second bending edge on the central part. The central part extends substantially parallel to the cable duct. In relation to the central part, the first and the second lateral part adopt a respective variable acute angle and a variable respective height. The first and second lateral part narrow the cable duct such that, in an assembled state, a respective end section of the first and second lateral part press against the cable with a respective elastic force and thereby bring about the strain- and pressure-resistant securing of the cable.

Abstract: An arrangement of an annular shielding element (1) comprises inwardly and outwardly pointing tabs (11, 12) on an insulating body (2) of a printed circuit board connector, for improving the electrical conductivity of both the earth connection between a plug connector housing (4)/device housing and a cruciform shield (31) of the insulating body (2)/a printed circuit board (5) associated therewith.

This is very important in particular when constructing electrical devices because, here, printed circuit boards (5) comprise a plurality of mounted insulating bodies (2) which are simultaneously inserted into the plug connector housing (4) of a housing wall (6) of the device housing.
