ABSTRACT:
A safety socket assembly comprising a non-conductive housing containing a pair of prong receptacles having conductive walls defining a prong slot adapted to receive the prongs of an electric plug, said walls having apertures therein adapted to receive locking means. A pair of corresponding terminals are positioned away from said prong receptacles. A spring loaded displaceable peg is situated between said prong receptacles having attached thereto a pair of flexible conductive contacts located adjacent the prong receptacles which have a forward locking head adapted to fit into the apertures in the receptacle walls when the peg is in a forward position and a tail portion adapted to contact the electrical terminals when brought into alignment therewith as the result of the spring loaded peg being rearwardly displaced. The prong receptacles, flexible contacts and electrical terminals are positioned such that when the peg is in a forward position the flexible contacts are engaged with the prong receptacles only and lock the peg in a forward position but, when the peg is depressed, the flexible contacts engage both the prong receptacles and corresponding electrical terminals.
