Abstract: A cable portion comprising a databus line (54) having one or more subscriber lines (52) connected thereto by a coupler device. The databus line and the subscriber line(s) each comprise a twisted pair of conductors protected by shielding. The coupler device comprises a coupler (53) providing data transmission between the two parts of the databus line and between the databus line and the subscriber line(s), and connectors (56A, 56B, 58) serve to connect the databus line with the subscriber line(s) in reversible manner. The coupler device presents weight of less than 70 g and is held by means of a fastener collar that enables the cable portion to be put into place in particularly practical manner in order to constitute a data transmission circuit.

Abstract: The invention relates to switching apparatus having a pair of input terminals (102, 104) and 2.sup.P pairs of output terminals (106a, 106b). The switch comprises p rows of switches K.sub.i,j with the ith row having 2.sup.i unit switches. It also comprises a control circuit (108) which enables the state of all the switches in a given row to be controlled together, thereby enabling the pair of input terminals to be connected to any pair of output terminals.

Abstract: A splicing device for connecting two electrical cables by forming a splice, each electrical cable including a sheath, a cladding and at least a first primary wire and a second primary wire. The cladding is surrounded by the sheath and surrounds the at least two primary wires. The splicing device includes a first electrical connector for connecting together the first primary wires of the two electric cables, and a second electrical connector for connecting together the second primary wires of the two electric cables. The splicing device further includes a first insulating sheath for covering the first electrical connector of the first primary wires, the first insulating sheath being made of a first material, and a second insulating sheath separated from the first insulating sheath for covering the second electrical connector of the second primary wires, the second insulating sheath being made of the first material.

Abstract: A device for connecting at least one braid of electric cables to a connector.The device comprises on the one hand a fastening plate provided with a slot, and on the other hand, a metal band of constant thickness and width. One end of the band passes twice through the slot to form two spires around the braid. The other end is subsequently backfolded on one edge of the fastening plate and severed.
