when in the locked state, the engaging piece 302 restricts the movement of the locking head 301 relative to the second connector 2 to restrict the first connector 1 from being disengaged from the second connector 2.
Referring to fig. 1 and 2, wherein the airtight connector assembly includes a first connector 1, a second connector 2, and a locking assembly 3, the first connector 1 is mounted on and communicates with a battery pack, and in the present embodiment, the first connector 1 communicates with a high-pressure side of the battery pack. The second connector 2 is used for communicating with an external air source, and the first connector 1 and the second connector 2 are inserted and communicated with each other so as to communicate the external air source with the battery pack, and the locking component 3 limits the first connector from being separated from the second connector 2, so that the insertion state between the first connector 1 and the second connector 2 is maintained.
Referring to fig. 5, the first connector 1 includes a connection head 101 and a connection plate 102, the connection plate 102 is fixed to the battery pack, and the connection head 101 is inserted into the connection plate 102 to communicate with the battery pack. In this embodiment, the number of the connecting heads 101 is two. The connectors 101 are each composed of a collar and an air column located in the collar.
Referring to fig. 6, the second connector 2 includes a body 201 and a first annular wall 202 provided on one end surface of the body 201. Two through holes are opened on one end face of the main body 201 to communicate with the two connectors 101 respectively. The first annular wall 202 is integrally formed on one end surface of the body 201, and the opening of the through hole on the end surface of the body 201 is located inside the first annular wall.
Referring to fig. 5 and 6, the connecting head 101 of the first connector 1 is inserted into the first annular wall 202 of the second connector 2, and the collar of the connecting head 101 is attached to the first annular wall 202, so as to ensure the sealing property of the connecting position between the connecting head 101 and the first annular wall 202.
