[0035] The flange mounting portion 111 and the flange mounting seat 25 are both fixed by a flange mounting connection method. Since the flange connection has a small connection thickness, it can meet the application requirements of a flat, thin and light liquid cooling module.

[0036] The socket outer shell 21 is radially floatingly mounted between the external threaded sleeve 24 and the flange mounting seat 25 .

[0037] In the present invention, the maximum radial floating amount of the socket outer shell 21 is 1.5 mm. Compared with the floating amount of less than 1 mm in the prior art, the present invention has a greater radial floating installation function, achieving a greater tolerance installation function without affecting the fluidity and sealing of the socket.

[0038] Part of the outer wall of the socket outer shell 21 protrudes outward to form a mounting ring 211. The flange mounting seat 25 is hollow. The flange mounting seat 25 has a first inner wall 251, a second inner wall 252 and a third inner wall 253 arranged in sequence. The inner diameter of the first inner wall 251 is larger than the inner diameter of the third inner wall 253. There is an internal thread mounting portion on the first inner wall. The internal thread mounting portion matches the external thread sleeve 24. When the internal thread mounting portion and the external thread sleeve 24 are in the assembled state, the mounting ring 211 of the socket outer shell 21 is clamped on the external thread sleeve and the second inner wall 252; the second inner wall 252 is perpendicular to the first inner wall 251; and / or the second inner wall 252 is perpendicular to the third inner wall 253; the first inner wall 251 is formed with an annular groove 254, the annular groove 254 is located between the internal thread mounting portion and the second inner wall 252, when the internal thread mounting portion and the external thread sleeve 24 are in an assembled state, the mounting ring 211 is opposite to the annular groove 254; the outer diameter of the mounting ring 211 is smaller than the inner diameter of the annular groove 254, and the outer diameter of the mounting ring 211 is larger than the inner diameter of the external thread sleeve 24.

[0039] The plug 10 further includes an annular valve core 12, a first return spring 13, a push rod 14, a first retaining ring 16 and a plurality of plug sealing rings 15;

[0041] The push rod 14 is assembled in the inner cavity of the plug shell 11 and fixed by the first retaining ring 16; when plugged into the socket 20, the push rod 14 maintains its position and squeezes the conical valve core 22 to move toward the tail of the socket shell 21, thereby opening the head flow channel of the socket shell 21.

[0042] The first return spring 13 is fixedly installed between the first retaining ring 16 and the annular valve core 12 and surrounds the periphery of the push rod 14; when inserted, the annular valve core 12 is squeezed by the socket outer shell 21 to move toward the tail of the plug outer shell 11, thereby opening the head flow channel of the plug outer shell 11. At this time, the first return spring 13 is compressed. When the socket 20 is pulled out, under the action of the rebound force of the first return spring 13, the annular valve core 12 automatically returns to its original position to close the head flow channel of the plug outer shell 11 and achieve sealing.

[0046] The second return spring 23 is fixedly installed between the conical valve core 22 and the second retaining ring 27. When inserted, the conical valve core 22 is squeezed by the push rod 14 to move toward the tail of the socket outer shell 21, thereby opening the head flow channel of the socket outer shell 21. At this time, the second return spring 23 is compressed. When the socket 20 is pulled out, under the action of the rebound force of the second return spring 23, the conical valve core 22 automatically resets to close the head flow channel of the socket outer shell 21 and achieve sealing.

[0047] The head of the plug housing 11 is processed into a trumpet shape, and the inner diameter of the head of the plug housing 11 matches the outer diameter of the head of the socket housing 21. The trumpet-shaped head of the plug housing 11 facilitates the alignment and insertion of the plug 10 and the socket 20.
