Abstract
An electrical connector with the function of instantaneous breaking of a current in response to detection of a leak. The connector comprises: a current supply cord for connecting a load to a source; a pair of plug blades connected electrically with the current supply cord and projected out of a connector body; a sensor mounted in the connector body for detecting a current leak; a breaker device for breaking the connection between the plug blades and the current supply cord in response to a detection by the leak detection sensor. Therein, the breaker device comprises: a pair of movable strips each having a portion thereof fixed to the connector body and a free end; a pair of stationary strips connected to the plug blades; a holder attached to the free ends of the movable strips; a lifter for pulling the holder such that the movable strips are contactual with the stationary strips in resistance to a spring action; a solenoid for being excited in response to a detection by the leak detection sensor; a plunger having a head engaged with the lifter for disengaging, by a move, the engagement between the lifter and the holder in response to excitement of the solenoid; a reset switch connected to the lifter with enablement of pivoting thereof; a spring for biasing the reset switch such that the movable strips tend to contact the stationary strips; thereby a push of the reset switch engaging a nail of the lifter with an engaging mate portion of the holder and in turn the movable strips being pulled toward the stationary strips to be contactual with thereof.
