[0022] The snap-fitting connection mechanism 4 comprises a slide groove 401, a limiting groove 402, a pin 403, an arc-shaped snap-fitting plate 404, a groove 405, a threaded groove 406, a handle 407, a spring 408 and an arc-shaped limiting plate 409.

The setting of spring 408 and arc-shaped limit plate 409. When in use, firstly thread pin 403 to the driving power supply, and then press arc-shaped limit plate 409. Arc-shaped limit plate 409 drives spring 408 to compress and deform, thereby making arc-shaped limit plate 409 slide in groove 405. When arc-shaped limit plate 409 is fully engaged in groove 405, one end of pin 403 is engaged in slide groove 401. When the position of limit groove 402 is relatively aligned with groove 405, spring 408 rebounds and deforms. Spring 408 drives arc-shaped limit plate 409 to slide, thereby driving arc-shaped snap plate 404 to move. When one end of arc-shaped snap plate 404 is in contact with the side wall of limit groove 402, the installation is completed. When pin 403 needs to be replaced, press handle 407. Handle 407 drives arc-shaped snap plate 404 to move. Repeat the above process to complete disassembly.

[0023] Furthermore, one end of the arc-shaped limit plate 409 is embedded in the interior of the groove 405, and the arc-shaped limit plate 409 forms a mutual sliding structure with the groove 405 through the spring 408. Through the setting of the arc-shaped limit plate 409, the arc-shaped limit plate 409 slides inside the limit groove 402 and the groove 405, so that the staff can quickly install or remove the pin 403, thereby facilitating the installation or replacement of the anti-interference capacitor and improving the service life of the equipment.

First, the bolt 305 is screwed into the inside of the threaded hole 302. After the installation is completed, vibration and impact will be generated during the use of the driving power supply. The shock absorbing block 303 can absorb and reduce the vibration and impact, and prevent it from being transmitted to the capacitor body 1, thereby protecting the equipment.

[0027] Furthermore, one end of the shock absorbing block 303 is in contact with the insulating protective layer 304, and the insulating protective layer 304 is made of rubber.

[0028] Working principle: first, thread the pin 403 to the driving power supply, then press the arc limit plate 409, the arc limit plate 409 drives the spring 408 to compress and deform, so that the arc limit plate 409 slides in the groove 405, when the arc limit plate 409 is completely embedded in the groove 405, one end of the pin 403 is embedded in the slide groove 401, when the position of the limit groove 402 and the groove 405 are relatively aligned, the spring 408 rebounds and deforms, the spring 408 drives the arc limit plate 409 to slide, and then drives the arc clamping plate 404 to move, when the arc clamping plate 404 When one end of the capacitor 403 is in contact with the side wall of the limiting groove 402, the installation is completed. When the pin 403 needs to be replaced, the handle 407 is pressed, and the handle 407 drives the arc-shaped clamping plate 404 to move. The above process is repeated to complete the disassembly. When the capacitor body 1 and the pin 403 are installed, the capacitor body 1 needs to be fixed. First, the bolt 305 is screwed into the inside of the threaded hole 302. After the installation is completed, vibration and impact will be generated during the use of the driving power supply. The shock-absorbing block 303 can absorb and reduce the vibration and impact, and prevent it from being transmitted to the capacitor body 1, thereby protecting the equipment.
