[0019] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0020] According to the instruction manual Figure 1-2It can be known that the quick connection mechanism in the utility model includes a pole plate 6, a limiter 8, a magnetic column 5 and a hook portion 4. When in use, the arc extinguishing chamber body 2 is placed on the top of the contactor body 1, aligned front and back and left and right, and can also be aligned through the alignment structure of the prior art, and the pole plate 6 is rotated, and the pole plate 6 rotates about the axis of the magnetic column 5. When it is rotated to the locked position, the hook 3 is hooked with the hook portion 4, and the limiter 8 is used to lock and limit the end face of the pole plate 6. At this time, the arc extinguishing chamber body 2 and the contactor body 1 are in a stable connection and fixation, and the positioning member 11 provides a vertical limit for the position of the pole plate 6 during the installation process. The contactor body 1 and the arc extinguishing chamber body 2 of the utility model are designed as separate bodies, and the contactor body 1 and the arc extinguishing chamber body 2 are fixed by a quick connection mechanism, which is convenient for quick disassembly and installation, simple structure, low failure rate, easy operation, and convenient for personnel maintenance and replacement. Refer to the attached manual Figure 1-2 The rotation direction of the pole plate 6 during installation depends on the specific position. For example, the pole plate 6 on the left side of the front side wall needs to be rotated clockwise when fixed. Those skilled in the art can make judgments and install it based on common sense.

[0021] The front and rear side walls of the arc extinguishing chamber body 2 are respectively provided with arc-shaped slideways 9 with the magnetic conductive column 5 as the center, and each pole plate 6 is provided with a pulley 10, which is slidably connected to the slideway 9, thereby ensuring the stability of the pole plate 6 during rotation.

[0022] Among them, the limiting member 8 includes a slide rail 14, a slide plate 13 and an elastic member 12. The slide rail 14 is arranged on the arc extinguishing chamber body 2. The slide plate 13 is slidably connected to the slide rail 14. The elastic member 12 is arranged between the inner side wall of the slide plate 13 and the inner side wall of the slide rail 14. The force of the elastic member 12 can make the slide plate 13 slide out to the end face position of the pole plate 6, thereby fixing its rotation direction.

[0023] Among them, a handle 7 is set at the end surface of the outer side of the electrode plate 6. The handle 7 and the electrode plate 6 can be designed as an integral part. When installing, just lift the handle 7 upwards, which is convenient for operation. The integral design improves the installation strength between the electrode plate 6 and the handle 7.

[0024] Among them, the hook and the plate are integrally formed to improve the installation strength between the plate and the hook.
