ABSTRACT:
The present invention is a quickly assembled electrical plug of dead front design. An integrally molded hinge connects the dead front terminal block to a first housing portion and a similar hinge connects the second housing portion to the first. Also connected by molded hinges to this composite assembly are two cord gripping strain relief fingers which are held in firm contact with the cord after assembly by a cover or shell. The line terminals are designed in connection with the terminal block so that their wiring screws all face in the same direction and may be connected to the cord conductors during assembly without rotation of the plug. After the cover shell is screwed onto the device, a ratchet assembly molded into one of the housing portions and cooperating with elements contained in the shell prevents inadvertent loosening of the shell.
