Abstract
A power cord connector engages a power outlet of the two wire or three wire types. The connector (plug) has a pair of spaced apart prongs in side by side parallel alignment and a grounding pin which is slidingly mounted within a recess in the connector body so as to be positionable between an extended position in parallel, spaced apart alignment with the prongs, and a retracted position fully enclosed within the recess. A biasing spring is positioned within the recess for urging the grounding pin into the extended position. A locking device includes a finger actuatable slide engaged with a tongue spring enabling the tongue to be moved into a locking position inhibiting retraction of the grounding pin.
Claims8
An electrical power connector apparatus for engaging a power outlet which comprises:
- a connector body integral with an electrical cord, the connector body having a pair of spaced apart prongs of an electrically conductive material, the prongs extending from a terminal surface of the connector body;
- and a grounding pin slidingly mounted within a recess in the connector body so as to be positionable between an extended position in parallel, spaced apart alignment with the prongs, and a retracted position fully enclosed within the recess;
- a biasing means positioned within the recess and engaged with the grounding pin for urging the grounding pin into the extended position;
- and a locking means comprising a finger actuatable element engaged with a tongue and enabling the tongue to move into a locking position inhibiting retraction of the grounding pin.
