(54) An alternating current socket-outlet for electric equipment


(57) An alternating current socket-outlet for electric equipments having a body member (10) fixed to a stationary system, a pair of connector members (20), a pair of shutter members (40a, 40b) movable between a first position to cover the connector members and a second position to uncover the connector member, an elastic member (30) urging the shutter members to the first position, and a front cover (50) to guide a pair of the pins (60) of a plug (200) adapted to engage the connector members (20).
In order to prevent an electric shock or fire accident, etc., the electric outlets covered by the shutter members (40a and 40b) are uncovered only when the two symmetric, equivalent pushing forces are applied to the shutter members.
