Abstract: A connector equipped with an insulant comprising four channels. Each channel is able to receive at the location of a rear extremity a strand of a cable, and at the location of a front extremity an end of a contact in order to connect each strand to an end. The connector comprises a ferrule equipped with four cavities arranged in such a way that a front extremity of each cavity coincides with a rear extremity of a channel of the insulant in such a way that each strand connected to an end in the connector extends in a cavity of the ferrule and in a corresponding channel of the insulant. The invention also relates to a process for fitting the coaxial cables in such a connector.

Abstract: An optical coupler (1) comprises two optical fibers (2, 3). Each of the optical fibers connects a sender unit (4) to a first end (9, 10). Then each of these fibers is connected independently to two independent receivers (6, 8). At the sender unit (4), the fibers are bared to be inserted into the same sleeve (15) which may be presented before the optical beam sent out by the sender unit. The bared intermediate zone between the sleeve and the non-bared cable portion is protected by a first sheath inside which the bared optical fibers are floating, and by a second protective sheath.

Abstract: Disclosed is a two-step method for crimping a contact (1) comprising a sleeve (7), the sleeve being provided with a cylindrical portion (14) and a truncated portion (18), about one end (2) of a cable (3) inserted in this sleeve. In the first step, the cylindrical portion is crimped around bared strands (10) of the cable by means of a first jaw (12). In a second step, while the crimping pressure exerted during the first step is maintained, a second jaw (13) is shifted axially along the sleeve so as to apply stress to outer walls of the tapering portion along the bared strands of the cable and also along a sheath (11) of the cable.

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.
