Abstract
The present invention provides an electrical plug receptacle which includes a housing including a cover having a primary wall and a perimetral wall respectively including a plurality of prong-receiving apertures, and a plate opposite to said primary wall, having a pair of prong projecting through holes and engaging with the cover so as to define an inner space of the housing, a conducting attaching set passing through the pair of prong projecting through holes from an inside of the housing and adapted for attaching the electrical plug receptacle to a wall receptacle, a retaining set encased in the housing, electrically connected to the conducting attaching set and corresponding to the plurality of prong-receiving apertures for retaining therein a plug of an electrical appliance, and a circuit encased in the housing and electrically connected to the conducting attaching set for protecting the electrical appliance when there is a surge voltage. Such an electrical plug receptacle receives the electrical appliance adaptors not only from the primary wall but also from the perimetral wall, and preferably includes a protective circuit which is highly recommended as a safety guard for effectively preventing accidents.
