Abstract

Abstract An upper and a lower body having three sockets, two on the upper portion and one on the center of the bottom face of the lower body. Each socket has a slide cover which fits into a track and which can slide back and forth to align and disalign with conductor prong holes. The slide covers each have hook-like legs which slideably secure them in slide cover leg slots. Retainers are on the inside of the upper and lower bodies to hold conductor plates in place. The prongs of a plug, when engaged with the present invention, fit through engagement slots on the slide covers and conductor prong holes to the protruberances of the conductor plate. When not in use, the slide cover can be slid to one side so as to close the passage to the conductor plate.
