the first plunger is arranged in the circulation cavity; a kind of electronic device with high-pressure air-conditioning system

The first reset piece is used for applying a reset force towards the flow pipe to the first plunger so that the first plunger seals the communication part between the flow cavity and the first fluid channel, and when the reset force of the first reset piece is overcome, the first plunger can move towards a direction away from the flow pipe so that the first fluid channel is communicated with the flow cavity;

wherein the flow tube is used for pushing the second plunger of the matched joint to move so as to unblock the second fluid channel in the matched body, so that the second fluid channel is communicated with the first fluid channel.

2. The connector of claim 1, wherein the plug body comprises a socket and a connector, the connector interfaces with the socket, the flow-through cavity is formed in the connector, and the plug cavity is formed in the socket.

3. The connecting joint according to claim 2, wherein a mounting part is sleeved on the outer side wall of the flow pipe, a mounting part is arranged on the outer wall of the mounting part, and the connecting seat is spliced with the splicing seat and clamps the mounting part.

4. A connector according to claim 3, wherein one end of the connector is a connecting end, a connecting cavity communicated with the circulation cavity is formed in the connecting end, and an external thread is arranged on the outer wall of the connecting end; the connecting end penetrates into the first plug-in end and is connected with the internal thread in a matched mode through the external thread, and the connecting end is propped against the mounting part; the outer wall of the mounting piece is in sealing abutting connection with the inner wall of the connecting cavity.

5. The connector of any one of claims 1-4, wherein a flow hole is formed in an outer side wall of an end of the flow tube away from the flow chamber, the flow hole being in communication with the first fluid channel, the flow hole being configured to communicate the first fluid channel with the second fluid channel.

6. The connector according to any one of claims 1 to 4, further comprising a sealing member, wherein the sealing member is disposed in the plugging cavity, a sealing cavity is formed in the sealing member, a sealing through hole is formed in a bottom wall of the sealing cavity, and an end of the flow pipe away from the flow cavity is penetrated in the sealing through hole; when the matching body is spliced with one end of the splicing body, the matching body can be penetrated in the splicing cavity and penetrated in the sealing cavity.

7. The connector fitting according to claim 6, further comprising a seal return member reciprocally movable on the flow tube, the seal return member being disposed within the mating cavity, the seal return member being adapted to apply a return force to the seal member in a direction away from the flow cavity such that a bottom wall of the seal cavity is abuttable against the mating body.

8. The connector of any one of claims 1-4, further comprising a stop member disposed on an inner wall of the plug body at an end thereof remote from the flow-through cavity, the stop member being capable of being stopped in a stop slot disposed on an outer wall of the mating body when the mating body is plugged with the plug body.

9. The connector of claim 8, wherein the limiting member is a ball, a rolling hole communicated with the plugging cavity is formed in an inner wall of one end of the plugging body, the ball is rotatably arranged in the rolling hole, and the ball can reciprocate along a radial direction of the flow pipe, so that the ball can at least partially extend into the plugging cavity.

10. A quick connector assembly, the quick connector assembly comprising:

the connection joint of any one of claims 1-9; a kind of electronic device with high-pressure air-conditioning system

The matching joint comprises a matching body, a second plunger and a second reset piece, wherein a second fluid channel is formed in the matching body, the second plunger is arranged in the second fluid channel, the second reset piece is connected with the second plunger, and the second reset piece is used for applying reset force to the second plunger so as to enable the second plunger to keep blocking the second fluid channel;

when the matching body is spliced with one end of the splicing body, the flow pipe pushes the second plunger to overcome the reset force of the second reset piece to remove the blocking of the second fluid channel, so that the second fluid channel is communicated with the first fluid channel in the flow pipe.
