Description

Technical Field

[0001] This utility model relates to the field of fluid connector technology, and in particular to a multi-directional, large-float, leak-proof fluid connector. Background Technology

[0002] Fluid connectors are widely used in liquid cooling systems. As an important connecting component in the cooling circulation system, fluid connectors require the connection and disconnection of male and female connectors during commissioning, maintenance, and replacement. However, due to factors such as processing errors of the cold plate and uneven mounting surfaces, radial offset and angular deviation of the male and female connector axes often occur. In existing technologies, the floating structure of fluid connectors uses the male connector to achieve radial compensation for small gaps through elastic elements. Its shortcomings are as follows: First, when the radial deviation is large, the existing floating structure cannot meet the radial compensation for large gaps, causing insertion and removal jamming or even inability to insert or remove, and failing to achieve rapid liquid cooling; Second, the existing floating structure cannot use angular offset. When the axis offset angle exceeds 1°, the floating sealing surface may cause insertion jamming or leakage due to misalignment; Third, the existing floating structure has no axial floating, which may cause leakage due to incomplete insertion and removal. Utility Model Content

[0003] To address one or more of the aforementioned problems, this invention provides a multi-directional, large-float, leak-proof fluid connector.

[0004] According to one aspect of the present invention, a multi-directional floating leak-proof fluid connector includes: a female base, a floating male head, and a multi-directional limiting part; The female seat includes a female seat shell, the liquid inlet pipe of the female seat shell is fixedly connected to the liquid supply circuit pipe, and its closed port can be opened by external force; The floating male connector includes a floating shell, the liquid outlet pipe of which is fixedly sleeved with a liquid cooling pipe and its closed port can be opened by external force, and a limiting end protruding from both ends of the floating shell is formed in the middle. The multi-directional limiting part includes a limiting seat with a detachable connecting head end fixing plate. The floating cavity of the limiting seat has a first through hole and a second through hole at its two axial ends, respectively. The limiting end of the floating shell has large radial and axial clearances in the floating cavity. Its liquid outlet tube passes through the first through hole with a large clearance, and its guide tube passes through the second through hole with a large clearance. When the floating male head is inserted into the female seat, the floating shell can float axially, float radially, and rotate circumferentially relative to the limiting seat to compensate for the radial deviation, axial deviation, and angular deviation of the floating male head and the female seat.

[0005] In some embodiments, a guide ramp is provided at the port of the female housing.

[0006] In some embodiments, the multi-directional limiting part further includes a limiting retaining ring. One end of the central shaft hole of the limiting seat is detachably connected to the limiting retaining ring and the other end is integrally connected to the fixed retaining ring. There is a floating cavity between the limiting retaining ring and the fixed retaining ring. The central hole of the fixed retaining ring is a first through hole and the central hole of the limiting retaining ring is a second through hole.

[0007] In some embodiments, a large-diameter mounting groove and a first shoulder are integrally formed at the inner end of the central shaft hole of the limiting seat. A circular groove is provided on the groove wall of the mounting groove. The limiting retaining ring is sleeved in the mounting groove with the inner end face of the ring fitting the first shoulder and the outer end face of the ring fitting the circular clamp. The circular clamp is installed in the circular groove.

[0008] In some embodiments, the inner end of the outer wall of the limiting seat protrudes radially to form a second shoulder and the outer end forms a first external thread. The head end fixing plate is threaded to the first external thread, and the locking nut is threaded to the first external thread and is in close contact with the outer wall of the head end fixing plate.

[0009] In some embodiments, a large-diameter screw hole ring is formed at the front end of the liquid outlet pipe, a circular protrusion is formed in the middle of the guide tube and a second external thread is formed at its rear end. The second external thread connects to the internal thread of the screw hole ring until the screw hole ring fits against the circular protrusion. The circular protrusion and the outer end wall of the screw hole ring are two limiting surfaces of the limiting end, and the diameter of the limiting surface is greater than the corresponding perforation diameter and less than the inner diameter of the floating cavity.

[0010] In some embodiments, the sealing groove of the guide tube is located between the annular protrusion and the second external thread, and the first sealing element is fitted into the sealing groove and fits the inner wall of the threaded hole annular port with an interference fit.

[0011] In some embodiments, the floating male connector also includes a first spring disposed in the guide tube of the floating shell and a male valve core connected to the front end of the first spring.

[0012] In some embodiments, the female seat also includes a female valve core, a push rod, and a second spring coaxially disposed within the female seat housing. The push rod and the front end of the female seat housing form an annular port, and the front end of the second spring is attached to the rear end of the female valve core. When there is no external force, the female valve core closes the annular port under the action of the second spring. When inserted, the female valve core is pushed into the rear end of the inner cavity of the female seat housing by the guide tube, and the male valve core is pushed into the rear end of the guide tube by the push rod, so that the two ports open to form a fluid flow channel.

[0013] In some embodiments, a third seal is provided on the outer wall of the front end of the push rod, and a fourth seal is provided on the front end of the inner wall of the female seat housing.

[0014] The beneficial effects of this multi-directional large floating leak-proof fluid connector are as follows: First, when the floating male and female are mated, the new floating structure can achieve radial, axial, and angular floating of large gaps, effectively realizing radial, angular, and axial compensation of large gaps. It is suitable for scenarios with large gap radial deviation, axial deviation, and axis deviation exceeding 1°. The fluid connector can be inserted and removed smoothly without jamming, and the leakage problem caused by incomplete insertion and removal is solved. Second, the new floating structure adopts the floating male head with an integral channel floating, avoiding the leakage problem caused by internal floating. Moreover, the overall structure is simple and easy to assemble. Attached Figure Description

[0017] Figures 1 to 7 A multi-directional, large-floating, leak-proof fluid connector according to one embodiment of the present invention is schematically shown. As shown, the multi-directional, large-floating, leak-proof fluid connector includes: a female connector 01, a floating male connector 02, and a multi-directional limiting part 03; The female connector 01 includes a female connector housing 1, the liquid inlet pipe 11 of which is fixedly connected to the liquid supply circuit's liquid passage pipe, and its closed port can be opened by external force. Preferably, the port of the female connector housing 1 is provided with a guide slope 10, which is biased for quick insertion and positioning.

[0018] The floating male head 02 includes a floating shell 3, the liquid outlet pipe 31 of the floating shell 3 is fixedly sleeved with the liquid cooling pipe and its closed port can be opened by external force, and the floating shell 3 has a limiting end 30 protruding from both ends in the middle. The multi-directional limiting part 03 includes a limiting seat 2 that is detachably connected to the head end fixing plate. The floating cavity 20 of the limiting seat 2 has a first through hole 201 and a second through hole 202 at its two axial ends. Preferably, the multi-directional limiting part 03 also includes a limiting retaining ring 6. The limiting retaining ring 6 is detachably connected to one end of the central shaft hole of the limiting seat 2, and the other end is integrally connected to a fixed retaining ring 21. The floating cavity 20 is between the limiting retaining ring 6 and the fixed retaining ring 21. The central hole of the fixed retaining ring 21 is the first through hole 201, and the central hole of the limiting retaining ring 6 is the second through hole 202. Its advantages are: the floating structure is easy to assemble and it is easy to obtain a larger floating gap.

[0019] The limiting end 30 of the floating shell 3 has large radial and axial clearances within the floating cavity 20. Its liquid outlet pipe 31 passes through the first through hole 201 with a large clearance, and its guide tube 32 passes through the second through hole 202 with a large clearance. When the floating male head 02 is inserted into the female seat 01, the floating shell 3 can float axially, float radially, and rotate circumferentially relative to the limiting seat 2 to compensate for the radial deviation, axial deviation, and angular deviation of the floating male head 02 and the female seat 01.

[0020] This multi-directional floating leak-proof fluid connector uses a female connector 01 with an automatic shut-off function and a floating male connector 02. Its floating structure features a large axial and radial clearance between the entire floating male connector 02 and the limiting seat 2 of the multi-directional limiting part 03. Therefore, the entire floating male connector 02 can move radially, axially, and rotate circumferentially within the space limited by the limiting seat 2. Its advantages are: First, when the floating male connector 02 and the female connector 01 are mated, the new floating structure can achieve radial, axial, and angular floating of the large clearance, effectively achieving radial, angular, and axial compensation of the large clearance. It is suitable for scenarios with large clearance radial deviation, axial deviation, and axis deviation angles exceeding 1°. The fluid connector can be inserted and removed smoothly without jamming, and the leakage problem caused by incomplete insertion and removal is solved. Second, the new floating structure uses the entire floating male connector 02 channel to float, avoiding the leakage problem caused by internal floating. Moreover, the overall structure is simple and easy to assemble.

The front end of the outlet pipe 31 forms a large-diameter screw hole ring 311, and the guide tube 32 forms a circular annular protrusion 321 in the middle and a second external thread at its rear end. The second external thread connects to the internal thread of the screw hole ring 311 until the screw hole ring 311 fits against the circular annular protrusion 321, forming a large-diameter limiting end 30 with a protrusion in the middle. The outer end walls of the annular protrusion 321 and the screw hole ring 311 are the two limiting surfaces of the limiting end 30, respectively. The diameter of the limiting surface is greater than the corresponding through hole diameter and less than the inner diameter of the floating cavity 20.

[0024] The diameter of the left end of the annular protrusion 321 is larger than the diameter of the second through hole 202 but smaller than the inner diameter of the floating cavity 20. The diameter of the left end face of the screw hole ring 311 is larger than the diameter of the first through hole 201 but smaller than the inner diameter of the floating cavity 20. The length of the limiting end 30 is smaller than the axial length of the floating cavity 20.

Its beneficial effect is that the setting has better sealing performance and achieves the effect of no liquid leakage when connecting and disconnecting.

The front end of the male valve core 021 is slidably connected to the port of the guide tube 32 with a uniform diameter and is slidably connected to the rear end of the guide tube 32 with a gap. When there is no external force, under the action of the first spring 022, the male valve core 021 closes the port of the guide tube 32. When inserted, the male valve core 021 is pushed into the guide tube 32 and opens the port. The front end outer wall of the male valve core 021 is provided with a second sealing element 023, and the ports of the male valve core 021 and the guide tube 32 are sealed by the second sealing element 023.

The female valve core 010 is slidably connected to the annular port with equal diameter and also slidably connected to the inner cavity of the female seat housing 1 with a gap. When there is no external force, the female valve core 010 closes the annular port under the action of the second spring 012. During insertion, the female valve core 010 is pushed into the rear end of the inner cavity of the female seat housing 1 by the guide tube 32, and the male valve core 021 is pushed to the rear end of the guide tube 32 by the push rod 011, thus opening both ports to form a fluid flow channel.
