A U-shaped bent piece pivots on one contact knife surrounding the contact knives above and below to a greater or lesser extent in accordance with how far it is pivoted and having two take-along openings through which the insulated conductor is inserted. The activating member and its motion require very little space. One of the contact knives itself is employed as a pivot for the activating member.

Abstract: A connector for clamping one or more electrical conductors has a shackle which cooperates with a screw serving to urge one end portion of a rail toward a bottom wall of the shackle. The bottom wall has a central portion flanked by two convergent lateral portions which guide one or more conductors against the internal surface of the central portion when the screw causes the end portion of the rail to approach the bottom wall. The underside of the end portion of the rail has a centrally located platform whose underside urges the conductor or conductors against the central portion of the bottom wall and which is assisted by two ridges disposed between pairs of recesses in the end portion of the rail. The lateral portions of the bottom wall have notches which receive portions of the platform, and the recesses receive portions of the corresponding lateral wall portions.

Abstract: To facilitate crimping, electrical crimp contacts comprising metal members and insulating members are manufactured in strip form. In a single injection molding operation, the insulating members are formed and attached to the metal members, and the insulating members are interconnected by integrally molding members. The latter may extend beyond the ends of the strip of contacts, so that such strips can be joined together.

Abstract: An electrical terminal unit, of the rail-mounted type, has terminals consisting of metal cntact parts with slots, and movable actuating members of insulating material provided with heads designed to receive and to entrain insulated conductors. The heads of the actuating members can be moved relative to the slotted contact parts so as to bring the inserted conductors into the slots, so that the slot edges cut the insulation and make contact with the conductor cores, and the connections can be broken by moving the actuating members away from the contact parts, thereby entraining the conductors and pulling these clear of the contact parts.
