Abstract:
A power plug assembly provided for an electronic device plugged into an AC outlet, comprising:a plug formed in one piece with a pair of terminals to be inserted into the AC outlet, and made of insulating material;a case which has a space retaining said plug so that said plug is pivotally movable in a predetermined angular range, exposing said terminals when the plug pivotally moves, and housing the terminals when not in use;a first resilient member housed in said case, and always biasing said plug in a direction so that said plug is housed;a first engagement part formed in said plug;a second engagement part to be engaged with said first engagement part when said plug is pivotally moved to a predetermined angle of said predetermined angular range forced against said first resilient member;engagement operator for engaging said second engagement part with said first engagement part; anda second resilient member for always biasing said engagement operator in a direction having engagement of said second engagement part with said first engagement part released, whereinwhen said plug is pivotally moved to the predetermined angle, said engagement operator is operated with a force against a resilience of said second resilient member so that said first and second engagement parts are engaged with each other and the plug is retained in a state ready for plug-in into the AC outlet, and when the engagement operator is released, the plug is automatically housed in said space due to resilience of said first resilient member.
