At the same time, by leaving enough space in the connecting slot shell, the bending of each coil connection wire is avoided, the service life of each coil connection wire is extended, and wear is reduced. At the same time, the installation and power connection are convenient, the overall structure has fewer welding points, the temperature rise of the structure is reduced, and the use effect of the structure is improved. At the same time, the leakage protector 5 and the short-circuit protector 6 are arranged here in this way. The leakage protector 5 here can be arranged to include a leakage protection frame, a leakage coil, a leakage push rod and a reset spring. The leakage protection frame is arranged close to the contact arm 41, and the leakage push rod is slidably arranged in the leakage protection frame.
