Abstract: Electrical connector, the two parts (1, 2) of which each comprise, in a housing (5, 8), an insulator divided into a front part (6, 9) and a rear part (7, 10) which are provided with retaining means (23) for the contacts (3, 4) and with means (15) for securing the retaining means (23) in the plugged-in position of the contacts (3, 4). The two parts (6, 7; 9, 10) of the insulator of the two connector parts (1, 2) may be injection moulded from plastic, without any remachining.

Abstract: Electrical connector with interlock, including a first part carrying at least one contact and a second part carrying at least one contact, each part having a housing in which the corresponding contact is held. An axially movable locking ring is mounted on the housing of the second part for locking the second part on the first part. The connector includes a retainer that retains the locking ring in the retracted position on the housing of the second connector part, a member for blocking the locking ring in the retracted position at the commencement of the fitting together of the housings of the two parts, a member for eliminating the effect of retaining the locking ring, a member for snap-fastening the two housings one on the other and unblocking the locking ring at the end of the fitting together of the two housings, and a member for locking the two housings in a snap-fastened position as a result of the axial advance of the locking ring.

Abstract: An electrical connection module receives terminal pins which are mounted on the ends of wires. The module includes a sheet metal connection piece which is bent into the shape of a pair of adjacent U-shaped sections. Each of these sections has a bottom, one branch provided with pink-guiding bosses, and another branch provided with a contact tongue which engages the pin. One of the branches has an upper portion provided with a locking catch for engaging the locking collar of a terminal pin. The connection piece can be subdivided into portions which are held in a housing which has a closing piece provided with pin-receiving orifices.

Abstract: Device for providing a direct electrical connection between the male terminal plugs of a plurality of cables comprises an elongated metallic member shaped to form at least one channel, one side of said channel being formed with resilient tabs which engage the ends of said plugs to make electrical contact therewith.

Abstract: Assembly comprises two parallel channel-shaped rails and pairs of jaws between the rails for gripping conductors extending transversely of the rails. Sides of one rail have external projections and the bottom of one jaw of each pair is also channel-shaped with its sides recessed to receive said projections with substantial tolerance. A spring is positioned between the channel-shaped bottom of the jaw and the mating rail which takes up the play due to the tolerance and electrically connects a grounding strip on the jaw to the rail.
