[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] A foldable soft cavity is provided on the outer end of the connector docking part, and an exhaust hole is provided on the inner side of the foldable soft cavity. When the connector body is docked and inserted, the connector body will squeeze the foldable soft cavity. At this time, the gas stored in the foldable soft cavity will be discharged outward through the exhaust hole, thereby cleaning the dust on the outer end of the connector docking part and reducing the impact on the docking operation.

[0025] When the docking connector is docked with the device, the heat generated by the device will be transferred to the docking connector, causing the temperature of the docking connector to rise.

After the docking is completed, the outer lock buckle is released. The outer lock buckle is reset and expanded under the drive of its own elastic force, thereby locking and limiting the connector docking part and reducing the possibility of the connector docking part falling off.

[0027] When the connector docking portion is docked with the connector body and the foldable soft cavity is squeezed, the gas inside the foldable soft cavity will synchronously enter the interior of the moving groove through the delivery tube. At this time, the moving block provided in the moving groove will slide along the interior of the moving groove under the push of the gas, and synchronously drive the connecting block to slide along the slide groove. At this time, the sliding connecting block will squeeze the elastic push piece, thereby causing the elastic push piece to undergo elastic deformation. The elastically deformed elastic push piece will resist the outer lock buckle through the auxiliary groove provided by the inner lock buckle, causing the outer lock buckle to further expand outward, thereby making the outer lock buckle fit more tightly with the inner groove of the connector body, further performing the lock limit, and improving the stability of docking;

[0028] A card block is provided on the inside of the connector cover, and a card slot is provided on the outside of the connector docking part. The connector cover and the connector docking part can be quickly assembled through the engagement and limiting between the card slot and the card block;

[0029] When the card block is docked into the card slot, the card block will synchronously squeeze the first spring piece. The first spring piece will be subjected to the resistance of the card block and will exert a moving force on the auxiliary spring piece. At the same time, the auxiliary spring piece and the first spring piece will synchronously have a reset tendency under the drive of their own elastic force, thereby further fixing the card block, so that the docking protrusion provided on the outside of the first spring piece can be more stably docked into the docking groove, and the card block is stably docked and engaged, further improving the stability of the docking between the connector cover and the connector docking part.

The inner lock buckle 3 and the outer lock buckle 4 are made of elastic deformable material, and the outer side of the outer lock buckle 4 is zigzag and concave, and the height of the outer lock buckle 4 gradually increases from the connection point to the outer end.

[0045] A foldable soft cavity 7 is provided on the outer end side of the connector docking part 2, and an exhaust hole 12 is provided on the inner side of the foldable soft cavity 7. When the connector body is docked and inserted, the connector body will squeeze the foldable soft cavity 7.

A foldable soft cavity 7 is provided on the outer end side of the connector docking part 2, and an exhaust hole 12 is provided on the inner side of the foldable soft cavity 7.

[0046] When the connector body is docked and inserted, the connector body will squeeze the folded soft cavity 7. At this time, the gas stored inside the folded soft cavity 7 will be discharged outward through the exhaust hole 12, thereby cleaning the dust on the outer end side of the connector docking part 2 and reducing the impact on the docking operation.

[0047] When the docking body is docked with the device, the heat generated by the operation of the device will be transferred to the docking body, causing the temperature of the docking body to rise. When the connector is unplugged, the foldable soft cavity 7 can be manually pressed to discharge the gas inside the foldable soft cavity 7 to the outside. The docking body is supplied with gas, and the gas can also cool the docking body to a certain extent.

[0048] An inner lock buckle 3 and an outer lock buckle 4 are provided on the outer side of the connector docking part 2. The preliminary lock docking of the connector body can be completed by the cooperation of the elastic force between the inner lock buckle 3 and the outer lock buckle 4. Pressing the outer lock buckle 4 makes the outer lock buckle 4 fit with the inner lock buckle 3, thereby facilitating the docking of the connector docking part 2 with the connector body. After the docking is completed, the outer lock buckle 4 is released, and the outer lock buckle 4 is reset and expanded under the drive of its own elastic force, thereby locking and limiting the connector docking part 2, reducing the possibility of the connector docking part 2 falling off.

[0053] When the connector docking portion 2 is docked with the connector body and the foldable soft cavity 7 is squeezed, the gas inside the foldable soft cavity 7 will synchronously enter the inside of the movable groove 9 through the conveying tube 8. At this time, the movable block 10 provided inside the movable groove 9 will slide along the inside of the movable groove 9 under the push of the gas, and synchronously drive the connecting block 20 to slide along the slide groove 14. At this time, the sliding connecting block 20 will squeeze the elastic push piece 11, thereby causing the elastic push piece 11 to undergo elastic deformation. The elastically deformed elastic push piece 11 will resist the outer lock buckle 4 through the auxiliary groove 13 provided by the inner lock buckle 3, so that the outer lock buckle 4 is further expanded outward, so that the outer lock buckle 4 is more closely fitted with the inner groove of the connector body, further performing the lock limit and improving the stability of docking.
