Abstract
This utility model discloses a household wall-mounted arc fault protection circuit breaker, including a housing with an assembly space inside. The assembly space houses a contact system, a tripping element, a PCB circuit board, and a handle. The housing also has a wiring port. The tripping element includes a coil frame, a tripping coil, a moving iron core, and a spring. Leads are connected to both ends of the tripping coil, and the two ends of the tripping coil are electrically connected to the PCB circuit board via the leads. A welding shaft is also provided on the coil frame, which is inserted into and welded to the PCB circuit board. The coil frame is welded to the PCB circuit board via the welding shaft to fix the tripping element. Leads extend from both ends of the tripping coil and are welded to the PCB circuit board to form an electrical connection. This method of fixing and separating the electrical connection solves the problem of short product lifespan caused by tripping vibration leading to tripping coil wire breakage during product use.
