ABSTRACT:
A safety receptacle for a two-piece duplex is disclosed. A pin is removably attached to a conventional male electric plug so that the pin extends outward in the same direction as the male plug's blades. A female electrical receptacle having at least one pair of hot
eutral slots encased in a housing, and adapted to receive the male blades, also includes a sleeve adapted to receive the pin.
A nonconductive, spring tensioned rack and pinion gear assembly is aligned to be workably connected to the pin. Each arm of a conductive pair of pivotal arms is connected at its one end to an electrical source and to the pinion. Each arm is aligned at its other end to make electrical contact with one of the pair of male blades so that when the pin is inserted into the sleeve, the pin engages and retracts the rack to a tensioned position, causing the pinion to rotate and pivot each of the arms into contact with the corresponding slot and thereby render the socket live. Removal of the male plug, and consequently the pin, causes the spring to relax, thereby urging the rack forward, causing each of the arms to pivot and break contact with the corresponding slot housing, thereby rendering the socket dead.
