The trigger buckle 412 cooperates with the buckle groove 431 so that the pressing device 4 can be stably maintained in the open state, making the installation of the AC contactor body 1 very smooth.

[0020] Further improvement, the transmission plate 43 is provided with a transmission plate handle 432 and a locking trigger 434. The setting of the transmission plate handle 432 facilitates pulling the transmission plate 43, and the setting of the locking trigger 434 is used to fix the clamping state of the clamping device 4; Figure 4 As shown, the locking trigger 434 includes a spring C4343, a lifting ball 4341, and a trigger block 4342. The spring C4343 and the lifting ball 4341 are set on the transmission plate 43, and the trigger block 4342 is set on the convex plate 3. When the transmission plate 43 moves to the position of the trigger block 4342, the spring will lift the lifting ball 4341 and enter the cavity where the trigger block 4342 is set, and push the trigger block 4342 out so that the transmission plate 43 can be fixed. Pressing the trigger block 4342 will push the lifting ball 4341 back to release the fixation of the transmission plate 43.

[0021] Further improvement, the end surface of the protruding plate 3 is provided with an opening A32, which is close to the bottom plate 2. The trigger 41 extends from the opening A32. When the AC contactor body 1 is set on the bottom plate 2, the trigger 41 can be directly contacted and pushed, making the installation of the AC contactor body 1 simple and convenient.

The support plate 22 supports the convex plate 3, increases the stability of the new type, and enables the AC contactor body 1 to be stably and reliably set on the bottom plate 2.

[0026] Working principle of the utility model

[0027] When installing this new device, the base plate 2 is screwed to the desired location for the AC contactor body 1. Due to the small size of the base plate 2, installation is relatively simple. After the base plate 2 is installed, the bottom surface of the AC contactor body 1 is aligned with the positioning protrusion 31, and the AC contactor body 1 is pressed downward, so that the trigger 41 is pressed downward. The trigger latch 412 disengages the latch groove 431, releasing the transmission plate 43. The released transmission plate 43 pushes the clamping block 42, causing the clamping device 4 to clamp the AC contactor body 1. The sound of the locking trigger 434 popping out indicates that the installation is complete.

[0028] When releasing the AC contactor body 1 , it is only necessary to press the lock trigger 434 and pull the transmission plate handle 432 to cause the transmission plate 43 to pull the clamping block 42 to release the clamping device 4 , and the AC contactor body 1 can be removed simply and conveniently.
