ABSTRACT:
A universal electric socket includes an insulative bottom shell having a pair of spaced ribs defining three separated chambers and three downwardly extending protruding portions below the chambers. An insulative cover shell covers the bottom shell so that the chambers are electrically insulated from one another. The cover may include ribs that interfit with the ribs of the bottom shell's ribs to isolate contacts disposed in the chambers. A grounding contact plate and two blade contact plates are respectively mounted in the chambers of the bottom shell. The grounding contact plate and the blade contact plates each have a plurality of receiving portions for receiving the grounding prong or blades of any of a variety of electric plugs. The blade contact plates each have a receiving portion and a wire clamp fastened to the receiving portion for holding the hot or neutral wire. Terminal blocks are respectively mounted in the protruding portions of the bottom shell and are respectively connected to the grounding contact plate and the blade contact plates. The terminal blocks each have a wire hole for receiving a wire, and a screw hole and a screw threaded into the screw hole for holding a wire. Thus, each of the contacts include both screw type clamps and wire push-in clamps for selective use.
