ABSTRACT:
Disclosed is a terminal block for providing electrical connection to insulated wire pairs. An entrance port of the block includes a blade for separating the wires as they are inserted therein. The wires are then positioned above a respective one of a pair of insulation displacement contacts. Pressure applied to the top of the block, as by screwing, drives each wire into its associated contact thereby causing penetration of the insulation for electrical connection. Posts may also be molded into the block to provide strain relief for the wires.
