Abstract: A tension-relieving assembly for electrical and/or optical conductors of a cable, wherein the conductors, which are guided in parallel in the cable, are held in a cable-guiding part and are inserted in conductor-guiding ducts in a conductor-guiding part, and wherein the axes of the conductors in the cable-guiding part and in the conductor-guiding part are offset relative to one another. The conductor-guiding part is provided, at the lead-in end for the conductors, with an annular collar, and a central peg is disposed in the annular collar. The cable-guiding part is constructed, at the conductor exit end, with a stepped recess, such that when the cable-guiding part and conductor-guiding part are joined together, the central peg is pressed between the conductors and forces the conductors outwards against the inner contour of the stepped recess in the cable-guiding part.

Front spring tongues of the contact socket act on the solid part of the contact pin, and the spring tongues of the contact pin act against the wall of the rear end of the contact socket.

Abstract: For a switch connector with contact elements disposed in contact cavities of an insulator body, with contact elements with at least one spring-elastic arm in the contact cavities, and in which contact blades of a corresponding mating connector can be inserted in the contact cavities and thus make contact with the contact elements and in which there is provided at least one shorting jumper which short-circuits two contact elements in the absence of an inserted mating connector, the short circuit being broken when the blade contacts are inserted in the contact cavities, it is proposed that the shorting jumper is designed as a rigid contact part and has at least one contact limb which is disposed between the contact spring limbs of the contact elements and that in the contact cavities there is a switching element provided with a switching spring limb, the switching spring limb acting on the contact spring limb of the contact element in such a way that the latter is displaced until the switching spring limb bears

Abstract: For a single-pole contact system for high currents, consisting of a rigid socket part (1) and a plug-in part (2) comprising elastic contact lamellae (16), it is proposed that the plug-in part (2) is provided with a pin-type projection (9), a cylindrical contact part (15), on which are fashioned elastic contact lamellae (16), is pushed on to the pin-type projection (9), the free ends of the contact lamellae pointing towards a conical transition (12) from the plug-in part (2) to the pin-type projection (9) and, at the front end of the projection, there is provided a pressure part (20) which acts on the contact part (15), the free ends of the contact lamellae (16) being pressed against the cone so that they are pressed radially outward, i.e., against the inside of the socket.
