Abstract: The present invention relates to the method and apparatus for manufacturing electrical connector pins. The method and apparatus make it possible to manufacture a pin from a blank of oblong shape (10), this blank being machined at different locations while held alternately by its ends (10A and 10B), the blank being moved from one location to another always substantially parallel to itself by means of gripping arms (27, 28, 61, and 60).

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.

Abstract: An electrical connector automatically protected against accidental disconnection. The electrical connector is formed from a plug and a base which are capable of being integrated by a fixation device to provide for the cooperation of contact terminals within insulating bodies each of which has at least one passage for at least one lead for connection to one of the contact terminals. The fixation device is associated with a locking device which is adapted to receive an unlocking order only when a detection device does not detect the presence of any current in at least one of the leads.

Abstract: An electrical connector has a socket member (1) with a body portion (2) having a tubular leading part (3) into which the tubular leading part (8) of a body portion (7) of a plug member (6) can engage. Locking is effected by means of a ring (11) which is retained on the plug member (6) and provided with an internal screw thread (14) co-operating with an external screw thread (5) on the leading part (3). When the ring (11) is screwed onto the socket (1) a leading end face (18) of the socket (1) is applied against an inclined face (17) of a tactile telltale (16) which is thereby urged outwardly of the ring (11) against the force of a return spring (19) to give a tactile indication to an inspector that the connector, which may be outside the field of vision of the inspector, is fully engaged.

Abstract: A self-stripping terminal for an electrical connector has a resilient fork formed of two prongs or limbs which extend towards each other, perpendicular to the longitudinal axis of the terminal. Defined between the ends of the prongs is an electrical conductor receiving slot formed with flat parallel walls and with a bevel configuration at the opening or mouth of the slot. The limbs are carried on resilient arms whereby the slot can resiliently open over a wide range of sizes to allow the terminal to accommodate a wide range of electrical conductor diameters and to be used repeatedly.The terminal may also include a second fork which is turned towards the first fork and which may be a semi-rigid fork or another resilient fork. In either case, the second fork has a groove for retaining the conductor, thereby to prevent radial disengagement thereof from the fork.The flat and bevel configuration is formed with walls that are parallel to the axis of the conductor received therein.

Abstract: An active optical coupler between an optical bus line and subscribers. The optical coupler couples an emitting optical conductor and a receiving optical conductor and includes a diversion device that allows passage of a fraction of the incident light transmitted to the receiving conductor while diverting another fraction of this incident light energy to a photoreceiver which controls the injection of light energy into the optical coupler with a control in the form of a photoemitter for controlling the light energy transmitted to the receiving conductor with restoration of the level. A switch controls the operation of the photoemitter which in turn can be controlled either by the photoreceiver or by an input signal emitted by the subscriber. Digital data can be transmitted to subscribers by means of an optical bus line.

Abstract: The connector comprises a base 1, enclosing an angle piece 7, and on which can be mounted two plugs, each comprising a tip 23 provided with a barrel 35 of square or rectangular section with bevelled edges, having a longitudinal bore 36, each barrel 35, when the plugs are assembled on base 1, being positioned against the angle piece 7 and coming face to face with one another, so that the ends of the optical fibers, each retained by gluing in a slot 37 formed at the end of each barrel 35 and opening into the longitudinal bore 36, will abut against one another.Application to the connection of optical fibers.

Abstract: A contact element of the self-stripping type, bearing two slots (15) and (17) into which the wires are radially introduced, and an additional radial anchoring slot (19) in the form of an interrupted ring of which the sides are elastic, due to a resilient region (D), and comprise regions (A, B, C) for introducting, shaping and radially anchoring the wire.

Abstract: A contact terminal for terminating a coaxial cable has a first conductor member with a U-shaped connection portion to receive the conductor core of the coaxial cable; and a second conductor member, electrically insulated from the first conductor member, also having a U-shaped connection portion to receive the conductor tube or screen of the coaxial cable. The second conductor member has a wider base portion than the base portion of the first conductor member. Both U-shaped connector portions are disposed in a line and opened in the same direction to permit the connection to be made merely by laying a partially stripped end of the coaxial cable into the opened connections and folding the opened legs of the first conductor member around the conductor core of the coaxial cable and the opened legs of the second conductor member around the conductor screen of the coaxial cable.
