Embodiment Construction
[0025] Such as figure 1 As shown, a specific embodiment 100 of a Ground Fault Circuit Interrupter (GFCI) receptacle is provided with a housing that includes a top cover 120, a middle frame 190 ( figure 2 shown) and base 150. The socket 100 includes a mounting iron frame 110 for fixing the socket on the junction box. Such as figure 2 As shown, the mounting iron frame 110 is provided with a threaded hole for receiving a grounding screw 180 connected to an external grounding wire.
[0026] The reset button 130 extends through an opening in the upper cover 120 of the housing. The reset button 130 is used to activate a reset operation, re-establishing the electrical connection in the broken conductive path. The test button 140 extends through an opening in the upper cover 120 of the housing. The test button 140 is used to break the electrical connection in the closed conductive path by simulating a fault condition.
[0027] Such as figure 1 and 13 As shown, when the termi...

The invention is a line breaker, comprising: a pair of stationary contacts, a pair of output sheets, a pair of dynamic contacts, a reset key, a movable part and a disengaging part containing a reset contact point. Each stationary contact is provided with stationary contact points, each output sheet is provided with output contact points, each dynamic contact is provided with an inactive end and anactive end provided with a first dynamic contact point for contacting with one corresponding output contact point and a second dynamic contact point for contacting with one corresponding stationary contact point. The movable part is arranged to a movable end supporting the dynamic contact, which is used for locking and releasing by the reset key, thus to move among the first position, the secondposition and the third position. Once a rest request is detected, the disengaging part can lock the reset key and the movable part when the movable part moves to the third position; once a fault stateis detected, the disengaging part can release the reset key from the movable part when the movable part moves to the first position.
Description
technical field [0001] The present invention relates to a ground fault circuit breaker (GFCI) device for protecting an AC load circuit, and more particularly, a GFCI with reverse wiring and end-of-life protection. Background technique [0002] With the widespread use of household electrical appliances, people hope that the socket installed on the electrical appliance body can avoid serious injury when accidental contact or other ground fault conditions occur. Therefore, a ground fault circuit interrupter is designed to break the electrical connection upon detection of a ground fault condition in an AC load. [0003] In the current market, there is a common phenomenon in the ground fault circuit breaker: that is, when the ground fault circuit breaker has entered the end of life, the user does not know it and uses it as a product with normal functions. Cause direct economic loss or harm to personal safety. [0004] The end-of-life period mentioned here refers to the failure ...
