Abstract: A cable connection unit for a connection box is provided including a cable, which has at least two electrical conductors surrounded by a cable sheath; a cable seal, which radially surrounds the cable sheath; and a cable organizer, in which the at least two electrical conductors are held in a fanned-out arrangement. A matching connection box has at least one receiving region for the cable connection unit, in which the cable seal and the cable organizer can each be placed. A cover of the connection box may then be folded down, whereby the electrical conductors of the cable are pressed into respective insulation displacement contacts of the connection region and thereby electrically contacted.

Abstract: A protective device (2) for sealing a plug connection consisting of a plug connector and a mating connector should be inexpensive and easy to manufacture. Preferably, it should be easy to retrofit the plug connection, when already installed/assembled, with the protective device (2). The protective device (2) is in the form of a single-piece protective cover (2). It consists of an elastic material, e.g. rubber, and is substantially tubular in shape, i.e. it is open on both sides and-apart from these two openings-sealed around its circumference. In particular, the protective cover (2) can be turned inside out so that it can be pulled over the already assembled plug connector from the plug-side direction, i.e. folded back. Preferably, the shape of the protective cover (2) may correspond to the outer contour of the plug connector.

Abstract: In order to produce a circuit board plug connector in which the advantages of hermaphroditic plug connectors are combined with the advantages of conventional plug connectors, a contact carrier is equipped with both plug contacts of a first type and plug contacts of a second type in equal numbers. Advantageously, the plug contacts of the first type are designed as “male” contacts (blade contacts) and the plug contacts of the second type are designed as “female” contacts (fork contacts) and can be plugged into one another in principle.

The invention is characterized in that the base part of the contact spring is releasably held on the contact part in that the base part has two support zones which engage on the contact part from opposite sides in positions at different distances to the clamping part.

Abstract: To reduce the manual effort and/or staffing involvement required in order to remove an electrical device (41) from an electrically wired device network (41, 42, 43) and/or to insert it therein, it is proposed that switching bridges (33) should be arranged in or on the cable mating connector housing (14) of a cable mating connector (1?).

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: 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: 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, 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.
