However, when quickly installing the AC contactor, the device requires the operator to fix the AC contactor with the shell, etc., which makes the device more inconvenient when installing and removing the equipment. At the same time, the device dissipates heat from the AC contactor, but the device needs to fix the AC contactor to the inside of the shell and then dissipate heat from the AC contactor, which reduces the practicality of the device.

[0024] Working principle:

[0025] When repairing the AC contactor:

[0026] The operator places the AC contactor on the surface of the support plate 201, and the operator pushes the support plate 201 so that the support plate 201 can drive the sleeve 203 to move synchronously, so that the sleeve 203 can compress the spring 204, and the support plate 201 can drive the inclined rods 202 on both sides to push the triangular blocks 206 on both sides to move synchronously, and the triangular blocks 206 on both sides can drive the connecting blocks 207 on both sides to move synchronously, so that the connecting blocks 207 on both sides can drive the clamping plates 4 on both sides to move synchronously, so that the clamping plates 4 on both sides can clamp and fix the AC contactor through the rubber plates 3 on both sides.

[0027] Fixation process:

[0028] After the AC contactor is clamped, the operator pulls the handle 802 so that the handle 802 can drive the ring 801 to move synchronously, so that the inner surface of the ring 801 is pressed against the surfaces of the connecting blocks 207 on both sides, so that the positions of the connecting blocks 207 on both sides are fixed. While the handle 802 moves, the threaded rod 805 can be driven to move synchronously, so that the threaded rod 805 moves to the threaded hole on the surface of the cylinder 1. The operator rotates the threaded rod 805 so that the threaded rod 805 can be threadedly connected to the threaded hole on the surface of the cylinder 1, so that the position of the ring 801 is fixed, and the clamping plates 4 on both sides can stably clamp the AC contactor to achieve quick installation. According to the above operations, the AC contactor can be quickly disassembled.
