During operation, when the distribution box body 1 is installed in an environment with large electromagnetic interference, the electrical components inside the distribution box body 1 will be damaged by electromagnetic interference, thereby causing electrical accidents. By setting the aluminum foil layer 15 inside the distribution box body 1, the interference electromagnetic can be effectively reflected and absorbed, and then the ground wire is connected to the end of the grounding connection rod 14 to introduce the electromagnetic absorbed by the aluminum foil layer 15 into the earth, thereby effectively reducing the interference of the electrical components in the distribution box body 1, thereby reducing the occurrence of accidents.

[0027] Further, such as Figure 3 - Figure 5As shown, the side wall of the fixed block 13 is provided with a sliding groove 2; the inner side wall of the sliding groove 2 is provided with a spring 21; the spring 21 is fixedly connected to the inner side wall of the sliding groove 2; the end of the spring 21 is provided with a sliding block 22; the sliding block 22 is fixedly connected to the end of the spring 21; the middle part of the grounding connecting rod 14 is provided with a slot 23. When working, when installing the grounding connecting rod 14, the grounding connecting rod 14 needs to be inserted into the fixed block 13. When the grounding connecting rod 14 is inserted into the fixed block 13, the grounding connecting rod 14 will slide The block 22 is inserted into the sliding groove 2. After the grounding connecting rod 14 is fully inserted into the fixed block 13, that is, the end of the grounding connecting rod 14 contacts the aluminum foil layer 15. After it is fully inserted into the fixed block 13, the spring 21 pushes the sliding block 22 into the card slot 23, thereby clamping the sliding block 22 inside the grounding connecting rod 14, thereby completing the fixation of the grounding connecting rod 14. Through the detachable installation method, it is effectively convenient for the staff to install and disassemble the grounding connecting rod 14, thereby facilitating the staff to fix the bottom line.

[0028] Further, such as Figure 1 - Figure 5 As shown, a fixing groove 3 is provided at the end of the ground wire connecting rod 14; a fixing bolt 31 is threadedly connected to the side wall of the ground wire connecting rod 14; a pressing plate 32 is rotatably connected to the end of the fixing bolt 31. During operation, when installing and connecting the bottom line to the end of the ground wire connecting rod 14, the staff inserts the ground wire into the fixing groove 3, and then uses a screwdriver to rotate the fixing bolt 31. Rotating the fixing bolt 31 pushes the pressing plate 32 to press the ground wire into the fixing groove 3, thereby completing the fixation of the bottom line. The detachable device effectively facilitates the staff to install and fix the ground wire.

[0029] Further, such as Figure 2 - Figure 4 As shown, the inner wall of the sliding groove 2 is provided with a limit ring 4; the limit ring 4 is fixedly connected to the inner wall of the sliding groove 2; the inner wall of the wire threading groove is provided with a rubber film 41; the rubber film 41 is fixedly connected to the inner wall of the wire threading groove.

During operation, when the sliding block 22 moves inside the sliding groove 2, the friction between the sliding block 22 and the limit ring 4 is effectively reduced by the arranged roller 51, so that the sliding friction between the sliding block 22 and the limit ring 4 is converted into the rolling friction between the sliding block 22 and the roller 51, thereby increasing the smoothness of the sliding of the sliding block 22 and reducing the wear of the equipment, thereby increasing the service life of the equipment.

[0031] Further, such as Figure 1 and Figure 2 As shown, a pair of exhaust holes 6 are provided on the side wall of the distribution box body 1; the exhaust holes 6 are symmetrically arranged; a plurality of connecting pieces 61 are fixedly connected to the side wall of the distribution box body 1. When working, the exhaust holes 6 provided on the side wall of the distribution box body 1 effectively improve the air flow inside the distribution box body 1, thereby reducing the accumulation of heat inside the distribution box body 1 and lowering the operating temperature of the electronic components inside the distribution box body 1.

When installing the ground wire connecting rod 14, the ground wire connecting rod 14 needs to be inserted into the fixed block 13. When the ground wire connecting rod 14 is inserted into the fixed block 13, the ground wire connecting rod 14 will squeeze the sliding block 22 into the sliding groove 2 After the grounding connecting rod 14 is fully inserted into the fixing block 13, that is, the end of the grounding connecting rod 14 contacts the aluminum foil layer 15, and after being fully inserted into the fixing block 13, the spring 21 pushes the sliding block 22 into the card slot 23, so that the sliding block 22 is stuck inside the grounding connecting rod 14, thereby completing the fixation of the grounding connecting rod 14.

When installing and connecting the bottom line to the end of the grounding connecting rod 14, the staff inserts the ground wire into the fixing slot 3, and then uses a screwdriver to rotate the fixing bolt 31. Rotating the fixing bolt 31 pushes the pressing piece 32 to press the ground wire inside the fixing slot 3, thereby completing The fixing of the bottom line is effectively facilitated by the detachable device for the staff to install and fix the ground wire. The setting of the limit ring 4 effectively limits the sliding block 22 to a certain position, so that the sliding block 22 moves at a certain position, thereby effectively reducing the displacement of the sliding block 22, thereby increasing the fixing effect of the equipment. When the cable is inserted from the threading groove into the distribution box body 1, the setting of the rubber film 41 effectively reduces the gap in the middle of the threading groove, thereby reducing the situation where mosquitoes enter the distribution box body 1. When the sliding block 22 moves inside the sliding groove 2, the setting of the roller 51 effectively reduces the friction between the sliding block 22 and the limit ring 4, so that the friction between the sliding block 22 and the limit ring 4 The sliding friction is transformed into rolling friction between the sliding block 22 and the roller 51, thereby increasing the smoothness of the sliding of the sliding block 22 and reducing the wear of the equipment, thereby increasing the service life of the equipment. By opening the exhaust holes 6 on the side wall of the distribution box body 1, the air flow inside the distribution box body 1 is effectively improved, thereby reducing the accumulation of heat inside the distribution box body 1 and the operating temperature of the electronic components inside the distribution box body 1. The connecting piece 61 is provided to facilitate the installation and fixation of the distribution box body 1 by the staff.
