[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5 The present invention provides a leakage current protection distribution box, comprising: a distribution box 1, a plurality of controllers 2 installed inside the distribution box 1, an auxiliary structure 3 on the upper surface of the distribution box 1, and a wire harness structure 4 inside the distribution box 1.

[0032] In the embodiments of this utility model, please refer to Figures 2 to 4The auxiliary structure 3 includes a limiting block 303, which is fixedly connected to the distribution box 1. A shaft 312 is rotatably connected to the inner wall of the limiting block 303. A connecting block 304 is fixedly connected to the arc surface of the shaft 312. A protective plate 301 is fixedly connected to the end of the connecting block 304 away from the shaft 312. Several slots 313 are opened on the inner wall of the protective plate 301. Several auxiliary blocks 314 are fixedly connected inside the slots 313. A connecting frame 305 is fixedly connected to the end of the auxiliary block 314 away from the slot 313. The shaft 312 has several... All arc surfaces are fitted with coil springs 311. The two ends of the coil springs 311 are fixedly connected to the limiting block 303 and the connecting block 304, respectively. Two sliding grooves 306 are opened on the upper surface of the distribution box 1. A slider 310 is slidably connected to the inner wall of the sliding groove 306. A spring 315 is installed inside the sliding groove 306. The two ends of the spring 315 are fixedly connected to the sliding groove 306 and the slider 310, respectively. A fixing rod 309 is fixedly connected to the upper surface of the slider 310. A stop rod 308 is fixedly connected to the upper end of the fixing rod 309. The stop rod 308 abuts against the connecting block 304. When the distribution box 1 needs to be opened for maintenance, the protective plate 301 is pulled to move it. The protective plate 301 moves the connecting block 304, which in turn moves the shaft 312 to rotate within the limit block 303. The connecting block 304 also causes the coil spring 311 to retract. Then, the protective plate 301 is opened. After the protective plate 301 is opened, the slider 310 is pulled to move it. The slider 310 moves the fixing rod 309, which in turn moves the stop rod 308. The slider 310 moves, causing the spring 315 to stretch. Then, releasing the slider 310 causes the spring 315 to contract, returning the slider 310 to its original position. The fixing rod 309 then drives the stop rod 308 to support the connecting block 304. The connecting frame 305 and the slot 313 allow for heat dissipation inside the distribution box 1. A limit rod 307 is fixedly connected inside the slide groove 306, slidingly connected to the slider 310. The spring 315 is fitted onto the arc surface of the limit rod 307. The limit rod 307 limits the spring 315, preventing deformation during use and extending its service life. A handle 302 is fixedly connected to the side of the protective plate 301 away from the distribution box 1; the handle 302 has a U-shaped cross-section. When it is necessary to move the protective plate 301, the handle 302 can be pulled. The handle 302 moves the protective plate 301, making it easier to move. The protective plate 301 is a transparent acrylic sheet with a rectangular cross-section. The transparent acrylic sheet allows for easy observation of the inner wall of the distribution box 1 at any time.

[0033] In the embodiments of this utility model, please refer to Figure 1 and Figure 5The wiring harness structure 4 includes a fixing plate 41, which is fixedly connected to the distribution box 1. Connecting plates 44 are slidably connected to the inner walls of both ends of the fixing plate 41. Positioning blocks 45 are fixedly connected to the interior of both ends of the fixing plate 41, and the positioning blocks 45 are slidably connected to the connecting plates 44. A clamping plate 42 is fixedly connected to the end of the connecting plate 44 away from the fixing plate 41. When wiring needs to be bundled, the clamping plate 42 is pulled to move, causing the connecting plates 44 to move. Then, the connecting plates 44 are separated from the positioning blocks 45 and the fixing plate 41. Next, the fixing plate 41 is separated from the clamping plate 42. The wiring is then placed into the fixing plate 41. The clamping plate 42 is then pulled to reset, fixing the connecting plates 44, the fixing plate 41, and the positioning blocks 45. The clamping plate 42 and the fixing plate 41 clamp and fix the wiring. Two positioning rods 46 are fixedly connected to the interior of both ends of the fixing plate 41, and the positioning rods 46 are slidably connected to the fixing plate 41. The positioning rod 46 can limit the position of the fixing plate 41, making the installation of the fixing plate 41 faster. Protective pads 43, which are rubber pads, are fixedly connected to the sides of the clamping plate 42 and the fixing plate 41 that are close to each other. The protective pads 43 can conveniently protect the wires clamped by the clamping plate 42 and the fixing plate 41, preventing wear and tear on the wires during wiring.

[0034] The working principle of the leakage current protection distribution box provided by this utility model is as follows: When the distribution box 1 needs to be opened for maintenance, the protective plate 301 is pulled to move it. The protective plate 301 drives the connecting block 304 to move. The connecting block 304 drives the shaft 312 to rotate on the inner wall of the limit block 303. The connecting block 304 drives the coil spring 311 to retract. Then the protective plate 301 is opened. After the protective plate 301 is opened, the slider 310 is pulled to move it. The slider 310 drives the fixed rod 309 to move. The fixed rod 309 drives the stop rod 308 to move. The slider 310 drives the spring 315 to stretch. Then the slider 310 is released. Spring 315 retracts, causing slider 310 to reset. Then, fixing rod 309 drives stop rod 308 to support connecting block 304. Connecting frame 305 and slot 313 can dissipate heat inside distribution box 1. Limiting rod 307 can limit spring 315 to prevent deformation during use and improve the service life of spring 315. When it is necessary to pull protective plate 301, handle 302 can be pulled. Handle 302 moves protective plate 301, making it easier to move protective plate 301. Transparent acrylic plate allows for easy observation of the inner wall of distribution box 1 at any time.

[0035] When it is necessary to bundle the wires, pull the clamp 42 to move it. The clamp 42 drives the connecting plate 44 to move, and then the connecting plate 44 is separated from the positioning block 45 and the fixing plate 41. Then the fixing plate 41 is separated from the clamp 42, and the wires are placed into the fixing plate 41. Then pull the clamp 42 to reset it, and fix the connecting plate 44, the fixing plate 41 and the positioning block 45. The clamp 42 and the fixing plate 41 clamp and fix the wires. The positioning rod 46 can limit the fixing plate 41, which can make the installation of the fixing plate 41 faster. The protective pad 43 can easily protect the wires clamped by the clamp 42 and the fixing plate 41, and prevent the wires from being worn during bundling.
