Description

Technical Field

[0001] The utility model relates to the technical field of water cooling, in particular to a water-cooling water-stop connector. Background Art

[0002] Existing high-power connectors have a need for cooling. The existing technology mainly adds a water cooling structure to the periphery of the contact. The water cooling structure is annularly sleeved on the contact to cool the outer ring of the contact. Since the contact is a conductive part, it is different from the traditional liquid cooling environment. Therefore, the liquid cooling plate uses a thermally conductive insulating material. When the temperature rise of the contact is too high, the water flow rate can be increased and the outflowing water can be cooled at the same time. The water pipes at the water inlet and outlet are connected to the liquid cooling plate with water pipe joints, which can reduce the temperature rise of the contact.

[0003] The utility model with application number CN202322554266.8 discloses a water cooling block for a water cooling radiator, including a base and a sealing cover sealed and installed on the base, the surface of the base is vertically connected with a plurality of mounting columns, the interior of the base is provided with a water inlet groove, a water outlet groove, a connecting groove and a plurality of circulation pipes, and the inner walls on both sides of each circulation pipe are fixedly connected with a plurality of baffles; the top surface of the sealing cover is fixedly connected with a water outlet and a water inlet, the surface of the sealing cover is provided with a plurality of mounting holes, and the sealing cover is attached to the surface of the base with a sealing gasket. The utility model slows down the flow rate of cooling water by adding baffles arranged in an equidistant manner on the inner walls on both sides of the circulation pipe, thereby achieving sufficient heat exchange between cooling water and CPU.

[0004] In the above scheme, when the water-cooling pipe and the water-cooling plate need to be replaced during use, the water-cooling pipe needs to be removed from the water-cooling joint. Since the water-cooling liquid flows between the water-cooling pipe and the water-cooling plate, when the water-cooling pipe is taken out, the water-cooling liquid will overflow, resulting in a large amount of water-cooling liquid leakage, which will damage the equipment that needs heat dissipation.

[0032] When the male connector 11 and the female connector 2 are separated, the water-cooling liquid located in the water-cooled heat sink 1 will be blocked by the male stop valve block 17, and the male stop valve block 17 will press against the port under the elastic action to prevent the water-cooling liquid from overflowing; after the female connector 2 is connected to the male connector 11, the valve opening member 3 in the female seat body 21 pushes open the male stop valve block 17, and the male stop valve block 17 is away from the port. At this time, the male connector 11 and the female connector 2 can be connected, and the water-cooling liquid can flow between the male connector 11 and the female connector 2, and the water-cooling liquid will not overflow after disassembly.

[0033] Specifically, the male seat body 12 and the male connecting pipe 13 are penetrated by a coaxially connected male through hole 14, and male stop structures 15 are respectively formed at both ends of the male through hole 14. A first elastic propping member 16 is provided between the two male stop structures 15 to press the male stop valve block 17 against the end; after the male connector 11 and the female connector 2 are separated, under the elastic action of the first elastic propping member 16, the male stop valve block 17 will be pushed to the end of the male through hole 14 and stopped by the male stop structure 15. At this time, the port of the male through hole 14 is pressed by the male stop valve block 17, and the water-cooling liquid in the male through hole 14 will not overflow.

[0034] Preferably, the first elastic stretching member 16 is a male compression spring, and the male stop valve block 17 is installed at the end of the compression spring. When the male connector 11 and the female connector 2 are separated, under the elastic action of the compression spring, the male stop valve block 17 can resist the male stop structure 15 at one end of the male through hole 14 to prevent the water-cooling liquid from overflowing from the end of the male through hole 14 and causing leakage.

[0035] A raised dividing block 24 is provided between the first connecting hole 22 and the second connecting hole 23. The male connecting tube 13 of the male socket body 12 is inserted into the rear end of the first connecting hole 22 and can abut against the dividing block 24. After the male connector 11 and the female connector 2 are connected, the male connecting tube 13 of the male socket body 12 just abuts against the dividing block 24 between the first connecting hole 22 and the second connecting hole 23.

[0036] Furthermore, the valve opening component 3 includes a valve opening block 31 located at the partition block 24, the valve opening block 31 is coaxially aligned with the male stop valve block 17, and after the male connecting pipe 13 is inserted into the first connecting hole 22, the valve opening block 31 can push the valve opening block 31 back, and after the male connector 11 and the female connector 2 are connected, since the male connecting pipe 13 just rests against the partition block 24, the valve opening block 31 will contact the male stop valve block 17 of the male connecting pipe 13 at this time, and the male stop valve block 17 will retreat along the male conducting hole 14, creating a gap with the male stop structure 15, and the water-cooling liquid can enter the female connector 2 from the male connector 11.

[0037] Specifically, the second connecting hole 23 is provided with a second elastic expansion member 35, and a female check valve block 33 is installed at the end of the second elastic expansion member 35. The female check valve block 33 presses against the dividing block 24. When the male connector 11 and the female connector 2 are separated, under the elastic drive of the second elastic expansion member 35, the female check valve block 33 presses against the dividing block 24, and the water-cooling liquid in the female connector 2 will not overflow; after the male connecting pipe 13 is inserted into the first connecting hole 22, the male connecting pipe 13 can press against the female check valve block 33, and the female check valve block 33 will retreat along the first connecting hole 22. There is a gap between the female check valve block 33 and the dividing block 24, and the water-cooling liquid can enter the female connector 2 from the male connector 11.

[0038] Furthermore, the female check valve block 33 is formed with a movable hole 34, and the valve opening block 31 is located in the movable hole 34. The female check valve block 33 can move axially along the second connecting hole 23 under the action of the second elastic propping member 35 or the male connecting pipe 13. The valve opening member 3 also includes a connecting column 32, one end of which is connected to the valve opening block 31, and the other end of the connecting column 32 is fixed to the other end of the second connecting hole 23. The position of the valve opening block 31 is fixed under the installation of the connecting column 32. When the male connector 11 and the female connector 2 are separated, under the elastic action of the second elastic propping member 35, the female check valve block 33 will press against the partition block 24, and the female check valve block 33 and the valve opening block 31 are radially aligned. The valve opening block 31 is located in the movable hole 34 of the female check valve block 33, and the female check valve block 33 and the valve opening block 31 cooperate to prevent the water-cooling liquid of the female connector 2 from overflowing. When the male connector 11 and the female connector 2 are connected, the male connecting pipe 13 is inserted into the first connecting hole 22 and abuts against the partition block 24. At this time, the open valve block 31 will contact the male stop valve block 17 of the male connecting pipe 13, and the male stop valve block 17 will retreat along the male conducting hole 14, creating a gap with the male stop structure 15, so that the water-cooling liquid can enter the female connector 2 from the male connector 11; at the same time, the male connecting pipe 13 can abut the female stop valve block 33, and the female stop valve block 33 will retreat along the first connecting hole 22. There is a gap between the female stop valve block 33 and the partition block 24, so that the water-cooling liquid can enter the female connector 2 from the male connector 11.

[0039] The female seat body 21 is formed with a connecting cylinder 25, and the first connecting hole 22 is formed in the connecting cylinder 25. The connecting cylinder 25 is slidably installed with a connecting sleeve 26 that can move axially along the connecting cylinder 25; the connecting cylinder 25 is radially formed with a plurality of radial grooves 27, and the radial grooves 27 are installed with guide balls 28. The connecting sleeve 26 can press the guide balls 28 to move along the radial grooves 27, and a part of the guide balls 28 is exposed in the first connecting hole 22; the male connecting tube 13 is formed with an annular groove 18 that rolls with the guide balls 28, and the connecting cylinder 25 is also nested with a guide compression spring 29.

[0040] In this embodiment, when the male connector 11 and the female connector 2 are connected, the connecting sleeve 26 is pushed inward, and the male connecting tube 13 is inserted into the first connecting hole 22 of the connecting tube 25. The male connecting tube 13 will open the guide ball 28, and the guide ball 28 will move radially outward along the radial groove 27. After being inserted into place, the guide ball 28 is radially aligned with the annular groove 18 of the male connecting tube 13. Then, the connecting sleeve 26 moves outward under the elastic action of the guide compression spring 29. The connecting sleeve 26 can press the guide ball 28 to move along the radial groove 27, so that the male connecting tube 13 can roll with the guide ball 28 to prevent the male connecting tube 13 from falling off from the first connecting hole 22.

[0041] When the male connector 11 and the female connector 2 need to be separated, the connecting sleeve 26 is pushed inward. At this time, the connecting sleeve 26 will not press the guide ball 28. When the male connector 11 is pulled out, the guide ball 28 can move radially outward along the radial groove 27 without blocking the annular groove 18 of the male connecting tube 13, and the separation can be completed.
