Patent ID: 7009473

Claim:
A circuit interrupting device comprising: a housing that includes a cover and a base; a mounting plate; an insulating member; and an electrical component mounting member, the mounting plate being disposed between the cover and the insulating member and is connected to a ground by a conductor, the insulating member being disposed between the mounting plate and the electrical component mounting member, and including hot and neutral output conductors, the electrical component mounting member being disposed between the insulating member and the base and within the base, and including hot and neutral input conductors for connecting to hot and neutral lines of a power source, a differential transformer for detecting a leakage current, a pair of connector arms disposed above and through the differential transformer and connected to the input conductors, a solenoid electrically connected at one end to the hot input connector, a plunger and a spring disposed inside the solenoid, and a disconnecting mechanism for connecting and disconnecting the output conductors to and from input conductors, the disconnecting mechanism including: two side arms respectively disposed below the connector arms, an L-shaped lock member slideably disposed below a through hole define in the disconnecting mechanism, the lock member defining an oval opening and a U-shaped slot for receiving a neck portion of the plunger, a cylindrical metal guiding member disposed in the through hole of the disconnecting mechanism and passing through the insulating member and the mounting plate, wherein a lower end of the guiding member has an end portion in the shape of a cone with a neck portion, a reset button fixed at an upper end of the guiding member, and a reset spring disposed near the upper end of the guiding member between the reset button and the insulating member.
