Electric cord connector

Insulation penetrating contact of a single piece electrical blade and contact is achieved in a connector of dead front construction by providing a single piece three link insulating housing adapted to fold up in valise fashion about the single piece blade and contact and about a wire extending into the housing. Electrical contact is made as the housing is closed and fastened in close form by forcing a bladed surface of the electrical contact into a channel in which the wire to be contacted is disposed.

A dead front plug is provided having an insulating housing with the general configuration of a valise. The electric cord enters the housing from the top of the valise. Strain relief is provided integral with the housing and comprises an annular channel around which the separated strands of the wire is directed. Radially extending pairs of walls in opposite sides of the valise press the two wire arcs into generally sinusoidal configuration along the length of each arc. Secure wire retention and strain relief is achieved.
