Abstract: A modular contact arrangement for connecting various protective and/or monitoring devices to phase lines 6, 7 of a cable head in a telephone distributor frame includes a plurality of spaced, springy contact blade pairs 5a, 5b, themselves arranged in associated pairs 51-52, 53-54, with a common ground bar 60 having individual springy fingers or blades 61, 62 interleaved between each associated pair in a comb-like manner. A circuit card 4 having three parallel conductive strips 41, 42, 43 printed on at least one face is configured to be insertable between two associated pairs of contact blades in a tongue-like manner such that electrical connections are established with such blades and with an interposed ground blade. Various circuit devices may be mounted on or connected to the card.

Abstract: A distribution frame for optical cables constituted by a plurality of cores (12) each supporting a plurality of optical fibers (13). The distribution frame comprises at least one cable head including at least one cassette (4) and a vertical duct (1), said duct is a generally channel section member having longitudinally extending grooves therein, and supports at least one tray (7) for jumpers (9). Adjacent each cassette (4) and inside the duct (1) there are storage means for receiving the cores (12), and advantageously constituted by drums (6) which are relatively displacable inside the duct in a vertical direction. The ducts also support, on their outside, three-way drums (22) associated with each cassette (4) and placed at the back of the cable head, and front drums (5) likewise associated with each cassette (4), said three-way drums (2) and front drums (5) serving to guide the jumpers (9).

Abstract: In a building electrical network including a power circuit constituted by several loops connected to sockets, lamps 35, 36, 37 and/or other electrically-operated apparatus, and a low-voltage circuit constituted by several loops connected to control means or sensors 38, 39, 40, 41 for controlling the loops of the power circuit, each loop of the low-voltage circuit and the corresponding loop of the power circuit are interconnected through a removable switching module 16 located in a centralized switching block 5. The low-voltage loops are not directly connected to terminals 12, 14 of the switching block, but are connected to terminals 45, 47 of a terminal strip 6, jumpers 46 establishing the connection between the terminals of the terminal strip(s) 6 and the terminals 12, 14 of the switching block 5. The plug-in switching modules 16 include an electronic relay member 21 (e.g.

Abstract: A cable head includes a plurality of modular connection units, the insulating base of which bears rear and front connection members, and one earthing component. The cable head includes, in addition for each connection unit, at least one protection module which can be plugged into the base from the front, the module comprising a body of insulating material exhibiting two side-housings intended to each receive one lightning arrester, and of two pairs of wrap-around contact components arranged on the body and effecting on the one hand the contact between the front and rear connection members arranged face to face and on the other hand the contact with earth, each pair of contact components associated with a lightning arrester ensuring both the retention of the lightning arrester in its housing and reinforcement of the clamping onto the tails of the lightning arrester upon plugging in the module.
