The dustproof cover 4 is provided to realize dustproof protection for the connecting base 1. When the connector is not in use, the connector 2 is disconnected from the connecting base 1. The rotating shaft 10 is loosened to make the two groups of sliders 5 on the connecting rod 6 slide relative to each other under the action of the first spring 7, thereby driving the two groups of dustproof covers 4 to slide relative to each other until the two groups of dustproof covers 4 fit together to wrap the connecting base 1. When the dustproof covers 4 fit together, the two groups of blocking blocks 15 interact with each other to make the slide bar 12 retract into the installation groove 11. The elastic force of the second spring 14 is smaller than that of the first spring 7, and does not affect the tightness of the closure of the two groups of dustproof covers 4. When the connector is not in use, the chance of the connecting base 1 contacting with the outside air is reduced, dust adhesion is reduced, and the sensitivity of the connector connection is ensured.

As shown in Figures 4 and 5, both groups of dust covers 4 are provided with mounting grooves 11, and sliding rods 12 are provided in the mounting grooves 11. Blocks 13 are sleeved on the sliding rods 12, and the sliding rods 12 are slidably connected to the dust covers 4 through the block 13.

Under the action of the first spring 7, the two sets of sliders 5 are driven to slide relative to each other, so that the two sets of dust covers 4 slide relative to each other until they are respectively fitted with the two sides of the connecting head 2. Under the action of the second spring 14, the sliding rod 12 drives the clamping block 15 to clamp with the clamping groove 16 on the connecting head 2. Under the action of the clamping block 15 and the clamping groove 16, the connecting head 2 will not easily fall off from the connecting seat 1, ensuring The stability of the connection between the connector 2 and the connector base 1. When the connector is not in use, the connector 2 is disconnected from the connector base 1. The rotating shaft 10 is loosened, and the two groups of sliders 5 on the connecting rod 6 slide relative to each other under the action of the first spring 7, thereby driving the two groups of dust covers 4 to slide relative to each other until the two groups of dust covers 4 fit together and wrap the connector base 1 inside. When the dust covers 4 fit together, the two groups of blocks 15 interact with each other to retract the slide bar 12 into the installation groove 11. The elastic force of the second spring 14 is smaller than that of the first spring 7, and does not affect the tightness of the closure of the two groups of dust covers 4.
