After the installation seat 200 is inserted into the installation groove 111, the conductive contact 700 is inserted into the conductive groove 112 to form a conductive connection.

[0021] like Figure 1 and Figure 2As shown, through the above arrangement, the switch box 100 in this embodiment is used to install the distribution switch body 600. The switch box 100 is installed in the corresponding area of ​​the mining area as needed to protect the internal switch structure. The distribution switch body 600 is arranged on the switch seat. The maintenance efficiency of the distribution switch is improved by the detachable assembly of the switch seat and the switch box 100. When the switch seat is installed, it is inserted into the installation groove 111 and the lower end of the switch seat is against the lower fixing block 400. The lower fixing block 400 is pressed down to make the upper end of the switch seat inserted into the position of the upper fixing block 300. The lower fixing block 400 applies a supporting force to the switch seat under the support of the elastic member 500, so that the switch seat is fixed under the clamping action of the upper and lower fixing blocks 400, ensuring the installation stability and preventing the switch structure from falling off. In addition, when the switch seat is inserted into the installation groove 111 to complete the fixation, the conductive contact 700 and the conductive groove 112 simultaneously form a conductive match, so that the distribution switch automatically conducts after the switch seat is installed, and the distribution switch automatically cuts off after disassembly, which is conducive to improving the safety during the disassembly and maintenance process.

[0022] like Figure 1 and Figure 2 As shown, after the installation of the distribution switch body 600 is completed, it is necessary to connect the corresponding distribution circuit in the wiring hole 113. In this embodiment, a clamp block is provided in the wiring hole 113, and the clamp block is movably connected with a fixing screw 800. The fixing screw 800 is screwed with the switch box 100, and the end of the fixing screw 800 is connected to a tightening part located outside the switch box 100. In this way, after the wire is inserted into the wiring hole 113, the clamp block is controlled by rotating the tightening part to clamp and fix the cable, thereby ensuring the stability of the circuit connection. At the same time, in this embodiment, an insulating protective sleeve 1200 for the cable to pass through is also fixed on the outside of the wiring hole 113. The insulating protective sleeve 1200 can be put on the cable to provide a certain insulation protection for the cable connection end, thereby ensuring the insulation protection effect of the cable connection.

[0024] Embodiment 2

[0025] like Figure 1 and Figure 2 As shown, the present embodiment further optimizes the structure of the switch box 100. In practical applications, when the power distribution switch inside the switch box 100 needs to be repaired and maintained, the switch box 100 needs to be opened. In the present embodiment, a switch port connected to the installation space 110 is provided on the front side of the switch box 100. The side wall of the switch port is hinged with an insulating switch cover 1300, and a sealing strip is provided on the edge of the switch port. In this way, the insulating switch cover 1300 is used to open and close the switch box 100. When the switch port of the switch box 100 is closed, the sealing strip is used to fill the internal gap to play a waterproof role. In addition, the present embodiment also provides a waterproof cover 1400 on one side of the upper end of the switch box 100 close to the switch port. The waterproof cover 1400 is arranged in an inverted U shape, and the upper end of the switch box 100 is provided with a guide groove 120 arranged on both sides of the switch box 100. The waterproof cover 1400 is used to cover the switch port position outside the switch box 100 to prevent accumulated water from flowing into the switch port from the switch port.
