Abstract: The invention relates to a contact for an electrical contactor protected by a polymer film and to its production process.This contact (3 or 7) has a contact resistance of at the most 10 ohms and incorporates a base metal coated by a 5 to 500 nm, homogeneous, adhesive organic polymer film. The polymer film can be deposited by the electropolymerization of a monomer such as acrylonitrile, followed by a heat treatment or irradiation to improve its electrical conductivity, so that a contact resistance not exceeding 10 ohms is obtained.

Abstract: A press-fit connector has an insulative body carrying a series of right-angle pins one branch of which can be force-fitted into a through-plated hole in a printed circuit. The insulative body comprises an angle-bracket having a mounting flange whose outside surface is adapted to bear against the board and a pressure block with bearing surfaces adapted to bear against the pins in order to apply to them a force which forces them into the through-plated holes and other bearing surfaces adapted to bear against the mounting flange. The geometry of the assembly is such that when the first bearing surfaces bear without external loading on the pins there remains a clearance between the second bearing surfaces and the mounting flange which is greater than the permanent deformation of the pins and the insulative body after the pins are forced in and the external loading is removed, so that the angle-bracket is held perfectly against the board.
Abstract: An electrical connector comprises a front insulating body formed with a plurality of parallel passages formed with respective abutment shoulders and having a rear tubular skirt; a plurality of electrical contacts each in a passage and in abutment against the shoulder thereof and an electrically insulating plate insertable into and within the skirt. The plate has catch fingers arranged for abutment against a rearwardly directed shoulder formed on each contact for locking the contact. The plate can be locked in abutment against the front insulating body. The passages in the front insulating body have such a shape that they prevent the catch fingers from spreading apart and that they maintain the catch fingers against the shoulders of the contacts when the plate is in abutment against the insulating plate.
Abstract: A distribution box has a housing carrying inlet and outlet connector sockets on two major faces and contains an internal printed circuit providing connections between the sockets and enabling the contacts of the connectors to be interconnected. The internal printed circuit is carried by two single-face boards placed back-to-back and interconnected by a flexible connecting circuit and the contacts of the connectors-and optionally of fuse-carriers placed on a single side of the board bearing the printed circuit are soldered in plate through-holes in the boards.
Abstract: The connector comprises an insulating support 20 in which are provided uniformly spaced passages and electrical signal contacts, each intended to connect a pad and a track, which are arranged in at least some of the passages.
Abstract: An electric test connector is arranged for temporary for connection with another connector, for checking the electric continuity of units connected to the other connector. It comprises: a pluggable casing and a lock carried by the casing and arranged for retaining the other connector. An electrically insulating plate is movable in the casing along the plugging direction and arranged for abutting connection with the front face of the other connector. The plate is resiliently biased. Electrical contact pins carried by said plate are resiliently biased forwardly towards a position where they have a predetermined amount of projection with respect to the plate. The pins are distributed according to a predetermined pattern corresponding to that of electrical contacts in the other connector.
Abstract: A system for connecting a flat shielded cable of the type comprising a stacking of three conductors, namely, one high voltage conductor and two low voltage equipotential conductors. The system comprises linking electric conductors partially uninsulated at their extremities, which are in intimate contact with corresponding tracks of the flat cable (10), elastic pads (40-43) making it possible to transmit sufficient pressure to the electric contact pickup linkages, and a casing (50, 51) formed of two half-shells closed on the unit constituted by the linkages and the elastic pads, and a device (60, 70) for retaining the two half-shells in either spaced apart or closed position. The system is used for the connection of high voltage cables.

Abstract: An electrical contact terminal for use in a connector comprises a body having a front tubular contact fractionated into circumferentially distributed contact fingers by longitudinal slots and a rear shank. The shank is shaped to receive an electric wire and is continuous, thereby improving connection with the wire. The connecting zone between the tubular contact and shank is radially expanded and the expansion is clamped in the flared end part of an external protection tube surrounding the front tubular contact.

A spring washer is axially retained between the stop ring and the flange. It has a plurality of keying fingers engaged into the slots for preventing mutual rotation of the housing and spring washer, is axially curved away from the housing between the fingers and is formed with projecting deformations located midway between the fingers for engagement into the ratchet identations by the resiliency of the washer.
Abstract: A prehension unit suitable for use as a finger in a manipulator hand has a supporting body, a contact element carried by the supporting body through a resilient material and defining with the body a closed space. Optical sensors cooperate with a locally light reflecting surface of the contact element. Each sensor comprises an optical fiber for transmitting light from a remote transducer to an end portion terminating in the supporting body in front of the contact element surface and an optical fiber for collecting the light reflected by the surface and conveying it to a remote light sensitive transducer. The movements of the locally reflecting surface, due to axial, radial and/or angular movements of the contact element which results in a change of the amount of reflected light collected by the second fiber may be detected. The manipulator apparatus may be provided with motors for restoring the unit to a position for which no force is exerted by an object to be seized on the contact element.
