Abstract: A protective housing for an elongated metal connector attached to the end of an electrical conductor wherein the connector comprises a tubular portion at its rear end for receiving the conductor and a contact portion at its forward end. The protective housing comprises a bottom section of rigid non-conductive material having a semi-cylindrical portion and a forward tubular portion for holding the metal connector. A top section of the housing fits against and is secured to the semi-cylindrical portion of the bottom section to form the assembled protective housing. Internal members within the top and bottom portions are adapted to engage the outer surface of the metal connector and provide heat insulgating air spaces around the metal connector within the assembled housing.

Abstract: An electrical plug connector adapted for connection with individual insulated wires of an electrical conduit comprises a housing having a plurality of elongated chambers each in line with a coupling element fixed in the housing. Each coupling element includes an elongated bifurcated jaw section having opposed inner knife edges that extend within an elongated chamber. A movable block within each housing chamber includes a first hole for receiving the end of an insulated wire to be terminally attached to a coupling element and a second hole for receiving a tool adapted to move the slider block within its chamber toward the jaw section of a coupling element so that the insulated wire previously placed within the slider block will move between the knife edges of the jaw section to provide an electrical contact. When each slider block is locked into its wire contacting position, the housing is closed and the connector is ready for use.
