Abstract
Abstract An electrical receptacle adapted to be secured in a power outlet box for interconnecting the prongs of a plug receptacle or wall switch to the powerlines leading into the outlet box. The receptacle has a plastic casing including a pair of metallic tubular conductors extending along opposite sidewalls of the casing against the backwall of the casing. Powerlines extend through the tubular conductors and are secured thereto by screws mounted transversely in the sidewalls of the tubular conductors. A plastic cover plate closes the receptacle and has three apertures respectively aligned with two conductor prongs secured to the tubular conductors and a third ground prong secured in the casing between the tubular conductors. Two additional tubular conductor elements are also secured in the casing, each having a screw for securing wires therein to enable the receptacle to accommodate various wiring or switch connections. Apertures are provided in the casing in axial alignment with the tubular conductors to facilitate insertion of wires therein. Similarly, apertures are provided in the casing to expose the screws for adjustment externally of the casing.
