ABSTRACT:
An input connection assembly comprises a holder of electrically insulating material having a well intermediate its ends, in which well are located at one end a U-shaped metal input terminal, at the other end a U-shaped metal output terminal, and intermediate the input and output terminals a U-shaped metal connection member. A jack plug can be inserted for test or interconnection purposes between said connection and terminal members. The holder contains two such current conducting systems in side-by-side relationship separated by insulating barriers and is received in a spring metal clip having an earth contact extending into the holder. Over-voltage protection devices are located between the input terminal members and the earth contact. A multiplicity of said assemblies are arranged in an array for terminating subscriber's lines at a telephone exchange. The terminal members have slots for stripping, connecting and holding wires.
