[0023] Example

[0024] An automotive wiring harness electrical box, such as Figures 1 to 5As shown, it includes a box body 1, an electrical component socket 3, a cover plate 7, an arc-shaped wire-passing tube 5, bolts 10, a heat dissipation device and a sealing device. The electrical component socket 3 is installed inside the box body 1, and one end of the top of the box body 1 is rotatably connected to the cover plate 7 through a hinge. One end of the cover plate 7 is fixedly connected to the box body 1 through a bolt 10. Arc-shaped wire-passing tubes 5 are installed on both side walls of the box body 1. The arc-shaped wire-passing tubes 5 are connected to the inside of the box body 1. The arc-shaped wire-passing tubes 5 are all arranged in an arc shape with one end of the outlet facing downward. A sealing device is provided on the arc-shaped wire-passing tubes 5, and heat dissipation devices are installed on both sides of the box body 1.

[0025] In order to further optimize the above scheme, the sealing device includes a waterproof cover 4, a strap 12, a Velcro thorn surface 13 and a molded fleece surface. The waterproof cover 4 is installed on the outer ring side wall of one end of the arc-shaped wire-passing tube 5. The waterproof cover 4 is installed at the downward outlet of the arc-shaped wire-passing tube 5. An arc-shaped slide groove 11 is opened in the side wall of one end of the waterproof cover 4. A strap 12 is slidably connected in the arc-shaped slide groove 11. One end of the strap 12 is fixedly connected to the side wall of one end of the arc-shaped slide groove 11. The other end of the strap 12 is installed with a Velcro thorn surface 13 and passes through the side wall of the waterproof cover 4. The side wall of the waterproof cover 4 is provided with a Velcro fleece surface 14. The Velcro thorn surface 13 is adhered and connected to the Velcro fleece surface 14.

[0026] In order to further optimize the above scheme, the heat dissipation device includes a heat dissipation pipe 6, a heat dissipation fan 15 and a dustproof net 16. The heat dissipation pipe 6 is installed on the two side walls of the box body 1. The heat dissipation pipe 6 is connected to the inside of the box body 1. The heat dissipation pipe 6 is arranged in an "L" shape and one end outlet faces downward. The "L"-shaped heat dissipation pipe 6 design effectively increases the heat dissipation area. At the same time, the heat dissipation fan 15 further improves the heat dissipation efficiency to prevent the internal temperature of the electrical box from being too high and causing damage to the components. The heat dissipation fan 15 is provided in the left heat dissipation pipe 6, and the dustproof nets 16 are provided in the heat dissipation pipes 6 on both sides to prevent dust and debris from entering the heat dissipation system and ensure its long-term stable operation.

[0029] In order to further optimize the above solution, a lighting lamp 9 is installed inside the box body 1. The design of the lighting lamp 9 makes it convenient to carry out maintenance work even in an environment with insufficient light.

[0030] Working principle: pass the cables of the electrical components through the arc-shaped wire-passing tube 5, insert the electrical components and the fuse on the top of the electrical component socket 3, seal and fix the cover plate 7 with two bolts 10, and then pull the strap 12 to tighten the strap 12. When tightened, the strap 12 can drive the waterproof cover 4 to tighten, so that the inner wall of the waterproof cover 4 fits tightly with the cable, and then adhere the Velcro thorn surface 13 to the molded fleece surface to tighten and fix the waterproof cover 4 to prevent water from entering the box body 1 through the cable when washing the car hood or engine, and to prevent impurities from entering the box body 1 along the gap between the cable and the arc-shaped wire-passing tube 5. By starting the cooling fan 15, air can be blown into the box body 1, so that the electrical components on the top of the electrical component socket 3 have good heat dissipation efficiency. The dustproof net 16 is provided to block impurities and dust to prevent impurities and dust from entering the box body 1.
