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.

A module for interconnecting a telephone incoming line to a telephone outgoing line, comprising:
- a base element including fastening means for fastening the base element onto a metal grounding rail, two channels for respectively receiving first and second wires of a telephone incoming line, and a grounding contact traversing the base element, said grounding contact being adapted to be electrically connected to the metal grounding rail;
- an intermediate element fitted onto the base element, said grounding contact extending into the intermediate element, said intermediate element comprising (i) upper and lower portions, (ii) first and second contacts including respectively first and second self-stripping portions each having a self-stripping slot, the first and second self-stripping portions extending into the base element, and (iii) third and fourth metal contacts each including third and fourth self-stripping portions each having a self-stripping slot and extending from the upper portion of the intermediate element;
- an upper element fitted onto the upper portion of the intermediate element, said third and fourth self-stripping portions extending into the upper element, said upper element including two channels for respectively receiving first and second wires of a telephone outgoing line, and a screw extending the upper element into said intermediate element, whereby tightening the screw forces said first and second wires of the telephone outgoing line against the third and fourth self-stripping portions, and biases the first and second self-stripping portions against the first and second wires of the telephone incoming line;
- and
- a lower element fitted onto the lower portion of the intermediate element, said lower element including a first terminal and first and second pairs of terminals, said first terminal being electrically connected to the grounding contact which extends into the intermediate element, said first pair of terminals electrically interconnecting the first contact to the third contact of the intermediate element, said second pair of terminals electrically interconnecting the second contact to the fourth contact of the intermediate element.
