[0002] Air switches and contactors are crucial components in electrical control systems. They play different roles within circuits, working together to effectively control them. Air switches primarily control the on / off state of circuits. Based on the principle of force balance and the fluid dynamics of gases, they achieve switching between on and off states through a combination of static and dynamic forces. Contactors, on the other hand, are electrical devices capable of switching high currents. Their primary function is to control the on / off state of circuits, enabling the start, stop, and normal operation of electrical equipment.

[0003] Existing air switches and contactors are mostly exposed to the outside air during use, which easily leads to the accumulation of a large amount of dust, affecting the normal operation of the air switches and contactors and also posing a safety hazard. Currently, no effective solution has been proposed to the problems in the relevant technologies. Utility Model Content

A connecting block 404 is provided at the top of the connecting cover 3, and a groove 405 is provided at the top of the dustproof shell 1, which matches the connecting block 404. A fixed block 406 is provided on the outside of the dustproof shell 1, and a fixed frame 407 is connected to the outside of the fixed block 406. A movable frame 408 is provided on one side of the fixed frame 407, and both ends of the movable frame 408 are connected to the clamping block 409. A clamping slot 410 is provided inside the connecting block 404, and the clamping block 409 matches the clamping slot 410. The fixed frame 407 and the movable frame 408 are connected by a first spring 6.

[0027] like Figure 1-Figure 4 As shown, the moisture-proof mechanism 5 includes a mounting frame 501 fixed to the inner wall of the dustproof shell 1, a placement box 502 is provided inside the mounting frame 501, and a through hole 503 is provided on the side wall of the placement box 502. By providing the placement box 502, it is convenient to place the dry particles. The through hole 503 is smaller than the dry particles to prevent the dry particles from falling out of the through hole 503. A mounting hole 7 is provided at the top of the dustproof shell 1, a mounting cover 8 is fixed inside the mounting hole 7, a wiring hole 9 is provided inside the mounting cover 8, a baffle 10 is provided inside the wiring hole 9, and a second slide groove 11 is provided inside the mounting cover 8. The baffle 10 matches the second slide groove 11, and a second slide plate 12 is provided under the baffle 10. One end of the second slide plate 12 is connected to the second spring 13, and the other end of the second spring 13 is connected to the fixed pile 14. A push plate 15 is provided above the baffle 10, and heat dissipation holes 16 are provided on both sides of the dustproof shell 1. A dustproof net 17 is provided on the outside of the heat dissipation hole 16, and the dustproof net 17 is connected to the dustproof shell 1. By setting the heat dissipation holes 16, the normal heat dissipation of the body 2 is ensured, and by setting the dustproof net 17, dust is prevented from entering the inside of the dustproof shell 1 from the inside of the heat dissipation hole 16.

[0028] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0029] In actual application, when it is necessary to use the main body 2 inside the dustproof shell 1, the movable frame 408 is pulled outward to drive the card block 409 away from the card slot 410, so that the card block 409 and the connecting block 404 have a restrictive effect. The connecting cover 3 drives the connecting cover 3 to fall downward under the action of gravity, so that the connecting block 404 contacts the inner wall of the bottom end of the dustproof shell 1, so that the connecting cover 3 stops falling. The operation is relatively simple. When the use of the main body 2 is finished, the connecting cover 3 can be pushed upward to make the first slide plate 401 slide inside the first slide groove 402. When the connecting block 404 is placed in the groove 405, the card block 409 is pulled again and then released. The card block 409 is engaged with the card slot 410 under the action of the first spring 6, and the connecting cover 3 can be opened. The main body 2 is fixed, thereby protecting the main body 2, and by setting a placement box 502, by placing dry particles inside the placement box 502, the moisture inside the dustproof shell 1 can be absorbed to prevent moisture from invading and damaging the main body 2, and after the dry particles have been used for a long time, the placement box 502 can be removed through the top of the mounting frame 501, which is convenient for replacing the dry particles inside the placement box 502 to ensure its drying effect, and when the main body 2 needs to be wired, the baffle 10 is driven to open by moving the push plate 15, so that the wire can pass through the inside of the wiring hole 9, and then by loosening the push plate 15, under the action of the second spring 13, the baffle 10 is driven to move, so that the size of the wiring hole 9 is consistent with the wiring size, preventing dust from entering the main body 2 through the wiring hole 9.

[0030] In summary, with the help of the above technical scheme of the present invention, by providing a dustproof shell 1 and a connecting cover 3, the internal body 2 can be protected and the body 2 can be isolated from the outside air. By providing a connecting mechanism 4, it is convenient to pull the movable frame 408 to make the block 409 away from the card slot 410, so that the connecting cover 3 falls to the bottom end of the dustproof shell 1 under the action of gravity. The operation is simple and convenient for using or repairing the internal body 2. By providing a moisture-proof mechanism 5, the moisture inside the dustproof shell 1 can be absorbed by placing dry particles inside the placement box 502 to avoid moisture intrusion and damage to the body 2. After the dry particles have been used for a long time, the placement box 502 can be removed through the top of the mounting frame 501, which is convenient for replacing the dry particles inside the placement box 502 to ensure its drying effect. A baffle 10 is provided inside the wiring hole 9, and the opening size of the baffle 10 can be adjusted according to the number of wirings of the body 2 to prevent dust from entering the body 2 through the wiring hole 9, thereby enhancing the dustproof effect of the dustproof shell 1.
