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 side of the connector docking part and reducing the impact on the docking operation. When the docking device is docked with the device, the heat generated by the operation of the device will be transferred to the docking device, causing the temperature of the docking device to rise. When the connector is unplugged, the folding soft cavity can be manually pressed to discharge the gas inside the folding soft cavity. The docking device is supplied with gas, and the gas can also cool the docking device to a certain extent. An inner lock buckle and an outer lock buckle are arranged on the outer side of the connector docking part.

When the connector docking part is docked with the connector body and the folded soft cavity is squeezed, the gas inside the folded soft cavity will synchronously enter the inside of the moving groove through the delivery pipe. At this time, the moving block arranged inside the moving groove will slide along the inside of the moving groove under the push of the gas, and synchronously drive the connecting block to slide along the sliding groove. At this time, the sliding connecting block will squeeze the elastic push piece, so that the elastic push piece will be elastically deformed. The elastic push piece after elastic deformation will resist the outer lock buckle through the auxiliary groove provided by the inner lock buckle, so that the outer lock buckle is further expanded outward, so that the outer lock buckle is more closely fitted with the inner groove of the connector body, and the lock buckle is further limited, thereby improving the stability of docking; A card block is arranged inside the connector cover, and a card slot is arranged outside 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. When the card block is docked into the card slot, the card block will synchronously squeeze the first spring sheet. The first spring sheet will exert a moving force on the auxiliary spring sheet due to the resistance of the card block. At the same time, the auxiliary spring sheet and the first spring sheet will synchronously have a reset tendency driven by their own elastic force, thereby further fixing the card block, so that the docking protrusion provided on the outer side of the first spring sheet can be more stably docked into the docking groove, and the card block can be stably docked and engaged, further improving the stability of the docking between the connector cover and the connector docking part.
