Description

A fluid connection component Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a fluid connection assembly. Background Technology

[0002] Fluids are substances that can continuously deform under any minute shear force; simply put, they are substances that can flow. In fluid transmission systems, fluid connectors are indispensable components, used to enable the rapid connection and disconnection of cooling pipes or other fluid transmission pipelines, while ensuring sealing under various conditions. With the rapid development of modern industrial technology, especially the ever-increasing requirements for heat dissipation efficiency and sealing performance in high-performance electronic equipment, aerospace, and medical devices, the design and performance optimization of fluid connectors have become particularly important.

[0003] Existing fluid connectors typically employ either plug-in or threaded connection methods. Plug-in fluid connectors are convenient to operate and save installation time, but they are inferior in terms of robustness and sealing. Furthermore, the lack of a convenient and reliable locking mechanism during plug-in and socket connection and disconnection results in a poor user experience during these operations.

[0004] Threaded connections achieve their purpose through tightening the threads, offering relatively high stability and sealing. However, threaded connections suffer from drawbacks such as long installation times and easy thread wear. Long installation times not only increase production costs but also negatively impact equipment assembly efficiency.

[0005] In conclusion, existing fluid connectors cannot provide both convenient installation and excellent sealing and securing performance. Technical solutions

[0006] The purpose of this invention is to provide a fluid connection assembly that solves the technical problem that existing fluid connectors cannot meet the requirements of convenient installation while possessing excellent sealing and fixing effects.

[0007] To achieve the above objectives, the present invention employs a fluid connection assembly, comprising a socket housing, a plug housing, a sliding support unit, a retaining unit, and a boss. The boss is fixedly connected to the plug housing, and a retaining groove is provided between the boss and the plug housing. The plug housing is adapted to the socket housing. The boss has a first inclined surface, a plane, and a second inclined surface. Both the first inclined surface and the second inclined surface have a first rounded corner structure between themselves and the plane.

[0008] The sliding support unit is slidably connected to the socket housing, and the sliding support unit has an avoidance groove;

[0009] The clearance groove on the sliding support unit is used to allow the holding unit to pass through when the plug housing and the socket housing are installed.

[0010] The holding unit includes a positioning steel ball and a movable steel ball. The socket housing has a positioning groove and a movable groove. The positioning steel ball and the movable steel ball are respectively placed in the positioning groove and the movable groove, and both are in contact with the sliding abutment unit.

[0011] The number of positioning steel balls and movable steel balls is multiple, and the number of positioning grooves and movable grooves is also multiple.

[0012] The diameter of the movable steel ball is equal to the diameter of the positioning steel ball.

[0013] The retaining unit includes a retaining ring and a return spring. The retaining ring has a sliding groove, which is slidably connected to the socket housing. The two ends of the return spring are fixedly connected to the socket housing and the retaining ring, respectively.

[0014] The sliding groove is provided with a limit step.

[0015] The retaining ring has two second rounded corner structures. Beneficial effects

[0016] The fluid connection assembly of the present invention, in practical use, enables insertion and locking through the provided sliding abutment unit and the locking unit. Furthermore, by pushing the sliding abutment unit, the locking unit can be placed within the clearance groove, thereby completing the unlocking. The first inclined surface, the plane, and the second inclined surface facilitate the sliding of the protrusion on the surface of the locking unit, improving installation efficiency. In this way, the technical problem of existing fluid connectors being unable to meet the requirements of convenient installation while possessing excellent sealing and fixing effects is solved.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Please refer to Figures 1 to 5, where Figure 1 is a structural schematic diagram of the fluid connection assembly of the present invention, Figure 2 is a schematic diagram of the state when the plug housing and the socket housing just come into contact during the assembly of the fluid connection assembly of the present invention, Figure 3 is a schematic diagram of the state when the boss contacts the movable steel ball during the assembly of the fluid connection assembly of the present invention, Figure 4 is a schematic diagram of the state when the boss pushes the movable steel ball during the assembly of the fluid connection assembly of the present invention, and Figure 5 is a schematic diagram of the state when the boss pushes the positioning steel ball during the assembly of the fluid connection assembly of the present invention.

[0026] This invention provides a fluid connection assembly, including a socket housing 1, a plug housing 2, a sliding support unit, a retaining unit, and a boss 3. The boss 3 is fixedly connected to the plug housing 2, and a retaining groove 4 is provided between the boss 3 and the plug housing 2. The plug housing 2 is adapted to the socket housing 1. The boss 3 has a first inclined surface 5, a plane 6, and a second inclined surface 7. The first inclined surface 5 and the second inclined surface 7 both have a first rounded corner structure 8 between them and the plane 6.

[0027] The sliding support unit is slidably connected to the socket housing 1, and the sliding support unit has a relief groove 18;

[0028] The clearance groove 18 on the sliding support unit is used to allow the holding unit to pass through when the plug housing 2 and the socket housing 1 are installed.

[0029] The holding unit includes a positioning steel ball 9 and a movable steel ball 10. The socket housing 1 has a positioning groove 11 and a movable groove 12. The positioning steel ball 9 and the movable steel ball 10 are respectively placed in the positioning groove 11 and the movable groove 12, and both are in contact with the sliding abutment unit.

[0030] The number of positioning steel balls 9 and movable steel balls 10 are both multiple, and the number of positioning grooves 11 and movable grooves 12 are also multiple.

[0031] The diameter of the movable steel ball 10 is equal to the diameter of the positioning steel ball 9.

[0032] The retaining unit includes a retaining ring 13 and a return spring 14. The retaining ring 13 has a sliding groove 15, which is slidably connected to the socket housing 1. The two ends of the return spring 14 are fixedly connected to the socket housing 1 and the retaining ring 13, respectively.

[0033] A limiting step 16 is provided inside the sliding groove 15.

[0034] In this specific embodiment, during actual use, the sliding abutment unit and the locking unit enable insertion and locking. By pushing the sliding abutment unit, the locking unit can be placed within the clearance groove 18, thereby unlocking. The first inclined surface 5, the plane 6, and the second inclined surface 7 facilitate the sliding of the protrusion 3 on the surface of the locking unit, improving installation efficiency. This approach solves the technical problem in the prior art where fluid connectors cannot achieve both convenient installation and excellent sealing and fixing effects.

[0035] The installation process is as follows:

[0036] In the initial state, the positioning steel ball 9 and the movable steel ball 10 are respectively placed in the corresponding positioning groove 11 and the corresponding movable groove 12. Then, the plug housing 2 is aligned with the socket housing 1, and the plug housing 2 is slowly pushed until the first inclined surface 5 of the protrusion 3 on the plug housing 2 contacts the movable steel ball 10. The plug housing 2 is pushed further, at which point the first inclined surface 5 will drive the movable steel ball 10 and the positioning steel ball 9 to move. The movable steel ball 10 will drive the sliding groove 15 of the retaining ring 13 to slide on the socket housing 1, and drive the spring to contract. When the limiting step 16 contacts the socket housing 1, the plug housing 2 is pushed further. At this point, the movable steel ball 10 and the retaining ring 13 will no longer move laterally, while the first inclined surface 5 will push the movable steel ball 10 toward the clearance groove 18. The first inclined surface 5 will drive the positioning steel ball 9 toward the clearance groove 18, continuing to push the plug housing 2. When the movable steel ball 10 and the positioning steel ball 9 come into contact with the plane 6, the spring will no longer be supported by the movable steel ball 10. The spring will return and extend, causing the retaining ring 13 to return and causing the movable steel ball 10 and the positioning steel ball 9 to slide down to the second inclined surface 7 and enter the retaining groove 4, thus pressing the movable steel ball 10 and the positioning steel ball 9 to complete the locking.

[0037] Conversely, the disassembly process is as follows:

[0038] Hold and push the retaining ring 13. After the retaining ring 13 moves to the designated position, pull the plug housing 2 backward. The second inclined surface 7 on the boss 3 will push the movable steel ball 10 and the positioning steel ball 9 into the relief groove 18. Continue to pull out the plug housing 2, so that the plane 6 contacts the positioning steel ball 9 and the movable steel ball 10. Continue to pull the plug housing 2, so that the positioning steel ball 9 and the movable steel ball 10 contact the first inclined surface 5. Then, completely remove the plug housing 2. At this time, the retaining ring 13 presses the positioning steel ball 9 and the movable steel ball 10 into the corresponding movable groove 12 and the corresponding positioning groove 11 under the reset characteristic of the spring.

[0039] Furthermore, the retaining ring 13 has two second rounded corner structures 17.

[0040] In this specific embodiment, the second rounded corner structure 17 makes it more comfortable to hold and push the retaining ring 13.

[0041] The installation process using a fluid connection component according to this embodiment is as follows:

[0042] In the initial state, the positioning steel ball 9 and the movable steel ball 10 are respectively placed in the corresponding positioning groove 11 and the corresponding movable groove 12. Then, the plug housing 2 is aligned with the socket housing 1, and the plug housing 2 is slowly pushed until the first inclined surface 5 of the protrusion 3 on the plug housing 2 contacts the movable steel ball 10. The plug housing 2 is pushed further, at which point the first inclined surface 5 will drive the movable steel ball 10 and the positioning steel ball 9 to move. The movable steel ball 10 will drive the sliding groove 15 of the retaining ring 13 to slide on the socket housing 1, and drive the spring to contract. When the limiting step 16 contacts the socket housing 1, the plug housing 2 is pushed further. At this point, the movable steel ball 10 and the retaining ring 13 will no longer move laterally, while the first inclined surface 5 will push the movable steel ball 10 toward the clearance groove 18. The first inclined surface 5 will drive the positioning steel ball 9 toward the clearance groove 18, continuing to push the plug housing 2. When the movable steel ball 10 and the positioning steel ball 9 come into contact with the plane 6, the spring will no longer be supported by the movable steel ball 10. The spring will return and extend, causing the retaining ring 13 to return and causing the movable steel ball 10 and the positioning steel ball 9 to slide down to the second inclined surface 7 and enter the retaining groove 4, thus pressing the movable steel ball 10 and the positioning steel ball 9 to complete the locking.

[0043] Conversely, the disassembly process is as follows:

[0044] Hold and push the retaining ring 13. After the retaining ring 13 moves to the designated position, pull the plug housing 2 backward. The second inclined surface 7 on the boss 3 will push the movable steel ball 10 and the positioning steel ball 9 into the relief groove 18. Continue to pull out the plug housing 2, so that the plane 6 contacts the positioning steel ball 9 and the movable steel ball 10. Continue to pull the plug housing 2, so that the positioning steel ball 9 and the movable steel ball 10 contact the first inclined surface 5. Then, completely remove the plug housing 2. At this time, the retaining ring 13 presses the positioning steel ball 9 and the movable steel ball 10 into the corresponding movable groove 12 and the corresponding positioning groove 11 under the reset characteristic of the spring.

[0045] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
