[0025] Working principle: When the utility model is in use, when assembling the electrical component body 5, it is installed on the connecting frame 16, and the mounting block 17 is inserted into the mounting groove 15 of the mounting plate 4. By pushing, it slides in the mounting groove 15, and after being moved to the inside of the chassis body 1, the mounting block 17 can be positioned and fixed by inserting the positioning column 18 into the positioning hole 14 to complete the installation. At this time, when connecting the connecting wire to the electrical component body 5, first thread the wire through the wire hole, and after winding the connecting wire around the rope reel 21, pass through the guide groove 10 to connect with the electrical component body 5. When it needs to be removed for maintenance, the positioning column 18 can be taken out by pulling the pull plate 19, and the connecting frame 16 can be pulled to move the electrical component body 5 to the outside of the chassis body 1. At this time, the positioning column 1 8 is inserted into the positioning hole 14 of the mounting plate 4 near the door 2, and can be plugged and positioned with the positioning hole 14 on the mounting block 17 to ensure that no sliding occurs during maintenance. When pulled, the electrical component body 5 moves, and the connecting wire can be moved, and then the rope reel 21 and the hollow shaft 20 can be rotated on the hollow heat-conducting rod 13. The volute spring 12 stores potential energy. After the maintenance is completed, when the electrical component body 5 is pushed in, the hollow shaft 20 can be rotated and reset with the potential energy of the volute spring 12, and the connecting wire can be wound with the rope reel 21. When in use, ventilation and heat dissipation can be carried out through the auxiliary heat dissipation holes 3. The drying plate 6 and the drying hole 7 cooperate to ensure the dryness of the inside of the chassis body 1. The outside air of the hollow heat-conducting rod 13 can flow through the internal through-holes, which can cool the wound connecting wire to a certain extent.
