Abstract: This invention relates to a terminal interface for interconnection of one or more subscriber telephone lines. The interconnections are made, in the interface box, by non-wire connections such as a bus composed of parallel and longitudinal blades or a cut-out circuit. The compartment for the Distributor receives a module for rapid interconnection of telephone lines, and preferably, a protective module and an R-C module. The connections for the Subscriber comprise, in addition to another rapid interconnection module, a telephone test socket which is associated with electro-mechanical means which electrically insulate the Subscriber's line from the incoming line as soon as it is desired to plug into this socket a conjugate telephone plug.

Abstract: This invention relates to a module for rapid interconnection of two monopair telephone lines by metal contacts with self-stripping slots. It comprises a base element which is fixed on the receiving metal rail, and which ensures connection of the incoming strands, an intermediate element which contains the major part of the connections for linkage, an upper element with master screw which ensures connection of the outgoing strands, and a fourth plug-in penta-pole element which forms a receptacle for an electrical circuit. The electrical circuit maintains electrical continuity, but may also, for example, receive an overvoltage arrester and possibly other additional components.

Abstract: This invention relates to a protection module provided to receive an overvoltage arrester in a receptacle and designed to plug on the protection ring of a telephone line interconnection module. The receptacle presents a receiving cavity adapted to receive overvoltage arresters of different dimensions, and it contains three elastic contacts, viz. two line contacts each with two contact strips and an earth contact with contact clamp. A thermofusible insulating shim is inserted between four additional earth lugs and the body of the overvoltage arrester in order to ensure short-circuiting of the latter in the event of functioning due to a lightning strike.

Abstract: Disclosed is a female socket of "modular jack" type, with integrated connections, wherein the modular jack contacts of the female opening of this socket are taken up at the rear on two series of self-stripping contacts at each of two self-stripping slots instead of one. Connection of a wire at the rear of the socket is effected, without specific tool, by closure of a rotating cover which is associated with these self-stripping contacts.
