[0034] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1 FIG. 1 is a schematic diagram showing the overall structure of an embodiment of a leakage protection switch provided by the present invention, and FIG. Figures 2 to 7 As shown, in this embodiment, the leakage protection switch is provided with a leakage protection switch body 1, a mounting back plate 2 and a wire harness anti-detachment mechanism 3, as shown in FIG. Figure 1 , Figure 2 and Figure 4 As shown, the leakage protection switch body 1 is fixedly installed in the middle of the mounting back plate 2 by bolts, and the wiring harness anti-slip mechanism 3 includes a first anti-slip plate 4 fixedly connected to the upper and lower ends of the mounting back plate 2, a second anti-slip plate 5 for limiting, a bent fixing strip 6 fixedly connected to the left and right sides of the rear end of the second anti-slip plate 5, and positioning grooves 7 arranged at equal intervals on the first anti-slip plate 4 and the second anti-slip plate 5. The leakage protection switch body 1 is fixedly installed at the corresponding position on the mounting back plate 2 by bolts, and then the external limit is docked and installed with the leakage protection switch body 1.

[0036] The existing leakage protection switch lacks a limiting mechanism for the wiring harness at the connection with the leakage protection switch body 1. If pulled, it is easy to cause the wiring harness to fall off from the leakage protection switch body 1, affecting the stability of connection and use. In the present invention, by setting a wiring harness anti-detachment mechanism 3, a fixing rod 8, a fixing cap 9 and a fixing plate 10, after the wiring harness is connected to the leakage protection switch body 1, the bent fixing strip 6 and the first anti-detachment plate 4 are snap-connected, and the upper and lower ends of the second anti-detachment plate 5 are fixedly connected to the fixing plate 10, and the left and right ends of the first anti-detachment plate 4 are fixedly connected to the fixing plate 10, and the upper and lower ends of the fixing plate 10 are plugged into the middle of the bent fixing strip 6. The fixing rod 8 is plugged into the middle of the fixing plate 10, and the outer surface of the fixing rod 8 is threadedly connected to the fixing cap 9, and the fixing cap 9 is fitted on the outer side of the fixing plate 10. The interface, positioning groove 7 and wire groove 16 on the leakage protection switch body 1 are all arranged in a one-to-one correspondence, such as Figure 2 , Figure 3 and Figure 5 As shown, the wiring harness is clamped in the positioning groove 7 in the middle of the first anti-slip plate 4, and then the second anti-slip plate 5 drives the positioning component 17 to be clamped in the middle of the first anti-slip plate 4. At this time, the wiring harness is clamped in the positioning groove 7 in the middle of the first anti-slip plate 4 and the second anti-slip plate 5. Then the fixing plate 10 is sleeved on the outside of the fixing rod 8, and the fixing cap 9 connected to the outer surface of the fixing rod 8 by rotating the thread is arranged. The fixing cap 9 and the fixing plate 10 are fitted together, and the fixing cap 9 pushes the fixing plate 10 to slide on the outside of the fixing rod 8. At this time, the upper and lower ends of the fixing plate 10 are respectively inserted in the bent fixing strip 6, so as to facilitate the limiting of the second anti-slip plate 5 and the first anti-slip plate 4. Through the arrangement of the first anti-slip plate 4 and the second anti-slip plate 5, it is convenient to clamp and fix the wiring harness connected to the leakage protection switch body 1, improve the stability of the connection between the wiring harness and the leakage protection switch body 1, and prevent it from falling off.

[0037] The existing leakage protection switch has a poor protection effect on the leakage protection switch body 1, and is prone to accidental touch, which poses certain safety hazards. In the present invention, by setting a fixed cover 11, a side plate 12, a fixed bracket 13, a spring 14, a fixed hole 15 and a wire groove 16, the fixed cover 11 forms a flip structure at the front end of the mounting back plate 2, and a torsion spring is provided at the connection between the fixed cover 11 and the mounting back plate 2. Wire grooves 16 are provided at both the upper and lower ends of the fixed cover 11, and the wire grooves 16, the positioning grooves 7 and the wiring ports on the leakage protection switch body 1 are arranged one by one. The right front end of the leakage protection switch body 1 is fixedly connected to the side plate 12, and the middle part of the side plate 12 is slidably connected to the fixed bracket 13, a spring 14 is provided between the fixed bracket 13 and the side plate 12, and the fixed bracket 13 is inserted into the flipped fixing hole 15, as shown in FIG. Figure 1 and Figure 7As shown, after the installation and the limiting of the wiring harness are completed, the fixing cover 11 is flipped over, and the fixing cover 11 and the mounting back plate 2 are rotated, the torsion spring at the connection between the fixing cover 11 and the mounting back plate 2 is elastically deformed, and then the fixing bracket 13 is pulled, and the fixing bracket 13 slides with the side plate 12, and the fixing bracket 13 squeezes the spring 14, so that the fixing bracket 13 is elastically deformed, and the fixing cover 11 is flipped over and fits on the front side of the mounting back plate 2, and then the fixing bracket 13 is directly released. At this time, the spring 14 restores the elastic deformation, and pushes the fixing bracket 13 and the side plate 12 to slide, so that the fixing bracket 13 is inserted into the fixing hole 15, as shown in Figure 7 In the state shown, the fixed cover 11 and the mounting back plate 2 are limited, and at the same time the wiring harness is clamped in the wire groove 16, and is covered on the outside of the leakage protection switch body 1 through the fixed cover 11, thereby facilitating the protection of the leakage protection switch body 1 and preventing accidental touching of the leakage protection switch body 1 when not in use.

By setting a fixed cover on the outside of the leakage protection switch body, the leakage protection switch body can be well protected, which prevents the leakage protection switch body from being accidentally touched when not in use. Combined with the setting of a fixed bracket, it is convenient to limit the fixed cover and the mounting back plate.
