ABSTRACT:
An electrical wire connector having a hollow, open-topped insulating body and an insulating cover formed to telescope with the body, the body and cover having complementary latches to retain them in an open position for insertion of wires and also to retain them in the closed position fully telescoped together. A slotted, flat plate, copper alloy wire connector element is retained on the base of a U-shaped wire cut-off and strain relief element centrally within the body. The wire cut-off and strain relief element is formed of a metal having a hardness greater than that of the wire connector element to provide the softer metal needed for the electrical contact in the connector element while providing the desired harder metal for cutting the wires and providing strain relief.
