Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a fluid connection component. Background Art

[0002] Fluid refers to a substance that can continuously deform under any slight shear force. In layman's terms, it is a substance that can flow. In the fluid transmission system, fluid connectors are indispensable components used to achieve rapid connection and disconnection of cooling pipes or other fluid transmission pipes, while ensuring sealing functions under various conditions. With the rapid development of modern industrial technology, especially the continuous improvement of heat dissipation efficiency and sealing performance requirements in high-performance electronic equipment, aerospace, medical equipment and other fields, the design and performance optimization of fluid connectors have become particularly important.

[0003] Existing fluid connectors usually use plug-in or threaded connection methods. Plug-in fluid connectors are easy to operate and can save installation time, but they are not good in terms of firmness and sealing. In addition, during the connection and separation of the plug and socket, this type of connector lacks a convenient and reliable locking mechanism, resulting in a poor experience during the plug-in and pull-out operation.

[0004] The threaded connection structure is connected by tightening the thread, which has relatively high fixity and sealing. However, the threaded connection has problems such as long installation time and easy wear of the thread. The long installation time not only increases the production cost, but also affects the assembly efficiency of the equipment.

[0005] In summary, existing fluid connectors cannot meet the requirements of convenient installation while having excellent sealing and fixing effects. Summary of the invention

[0006] The object of the present invention is to provide a fluid connection assembly, aiming to solve the technical problem that the fluid connector in the prior art cannot meet the requirements of convenient installation while having excellent sealing and fixing effects.

[0007] To achieve the above-mentioned object, the present invention adopts a fluid connection assembly, comprising a socket housing, a plug housing, a sliding holding unit, a holding unit and a boss, wherein the boss is fixedly connected to the plug housing, a holding 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, and a first rounded corner structure is provided between the first inclined surface and the second inclined surface and the plane;

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

[0009] The avoidance groove on the sliding holding unit is used for allowing the holding unit to avoid when the plug housing and the socket housing are installed.

[0010] Wherein, 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 holding unit.

[0011] Therein, the number of the positioning steel balls and the number of the movable steel balls are both multiple, and the number of the positioning grooves and the number of the movable grooves are also multiple.

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

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

[0014] Wherein, a limited step is arranged in the sliding groove.

[0015] Wherein, the clamping ring has two second rounded corner structures.

[0016] A fluid connection component of the present invention, when in use, can achieve insertion and locking through the provided sliding abutment unit and the clamping unit, and can place the clamping unit in the avoidance groove by pushing the sliding abutment unit, thereby completing unlocking. The first inclined surface, the plane and the second inclined surface can more conveniently allow the boss to slide on the surface of the clamping unit, thereby improving installation efficiency. In this way, the technical problem that the fluid connector in the prior art cannot meet the requirements of convenient installation while having excellent sealing and fixing effects is solved.

[0026] The present invention provides a fluid connection assembly, comprising a socket housing 1, a plug housing 2, a sliding abutment unit, a clamping unit and a boss 3, wherein the boss 3 is fixedly connected to the plug housing 2, a clamping 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, and a first chamfered structure 8 is provided between the first inclined surface 5 and the second inclined surface 7 and the plane 6;

[0027] The sliding abutment unit is slidably connected to the socket housing 1, and the sliding abutment unit has an avoidance groove 18;

[0028] The avoidance groove 18 on the sliding holding unit is used for allowing the holding unit to avoid 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 holding unit.

[0030] The number of the positioning steel balls 9 and the number of the movable steel balls 10 are both multiple, and the number of the positioning grooves 11 and the number of the 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 clamping unit includes a clamping ring 13 and a return spring 14. The clamping ring 13 has a sliding groove 15. The sliding groove 15 is slidably connected to the socket housing 1. Both ends of the return spring 14 are fixedly connected to the socket housing 1 and the clamping ring 13 respectively.

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

[0034] With respect to this specific embodiment, during specific use, the sliding abutment unit and the clamping unit are provided to achieve insertion and locking, and the clamping unit can be placed in the avoidance groove 18 by pushing the sliding abutment unit, thereby completing unlocking. The first inclined surface 5, the plane 6 and the second inclined surface 7 can more conveniently allow the boss 3 to slide on the surface of the clamping unit, thereby improving the installation efficiency. In this way, the technical problem that the fluid connector in the prior art cannot meet the requirements of convenient installation while having excellent sealing and fixing effects is solved.

[0035] The installation process is as follows:

[0036] In the initial state, the positioning steel ball 9 and the movable steel ball 10 are placed in the corresponding positioning groove 11 and the corresponding movable groove 12 respectively, 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 boss 3 on the plug housing 2 contacts the movable steel ball 10, and the plug housing 2 is continued to be pushed. At this time, the first inclined surface 5 will drive the movable steel ball 10 and the positioning steel ball 9 to move, and the movable steel ball 10 will drive the sliding groove 15 of the clamping 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 continued to be pushed. At this time, the movable steel ball 10 and the clamping ring 13 will no longer move laterally, and the first inclined surface 5 will push the movable steel ball 10 to move toward the avoidance groove 18, and the first inclined surface 5 drives the positioning steel ball 9 to move toward the avoidance groove 18, and continues to push the plug housing 2, so that when the movable steel ball 10 and the positioning steel ball 9 contact the plane 6, the spring is no longer resisted by the movable steel ball 10, and the spring resets and stretches to drive the clamping ring 13 to reset and drive the movable steel ball 10 and the movable steel ball 10 and the positioning steel ball 9 to slide to the second inclined surface 7 and enter the clamping groove 4, and the movable steel ball 10 and the positioning steel ball 9 are pressed to complete the locking.

[0037] Otherwise the disassembly process is as follows:

[0038] Hold and push the clamping ring 13. After the clamping ring 13 moves to the specified position, pull out the plug housing 2 backwards. The second inclined surface 7 on the boss 3 will push the movable steel ball 10 and the positioning steel ball 9 into the avoidance 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 take out the plug housing 2. At this time, the clamping 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 characteristics of the spring.

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

[0040] According to this specific embodiment, the second rounded corner structure 17 can make it more comfortable to hold and push the clamping ring 13.

[0041] Using a fluid connection assembly of this embodiment, the installation process is as follows:

[0042] In the initial state, the positioning steel ball 9 and the movable steel ball 10 are placed in the corresponding positioning groove 11 and the corresponding movable groove 12 respectively, 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 boss 3 on the plug housing 2 contacts the movable steel ball 10, and the plug housing 2 is continued to be pushed. At this time, the first inclined surface 5 will drive the movable steel ball 10 and the positioning steel ball 9 to move, and the movable steel ball 10 will drive the sliding groove 15 of the clamping 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 continued to be pushed. At this time, the movable steel ball 10 and the clamping ring 13 will no longer move laterally, and the first inclined surface 5 will push the movable steel ball 10 to move toward the avoidance groove 18, and the first inclined surface 5 drives the positioning steel ball 9 to move toward the avoidance groove 18, and continues to push the plug housing 2, so that when the movable steel ball 10 and the positioning steel ball 9 contact the plane 6, the spring is no longer resisted by the movable steel ball 10, and the spring resets and stretches to drive the clamping ring 13 to reset and drive the movable steel ball 10 and the movable steel ball 10 and the positioning steel ball 9 to slide to the second inclined surface 7 and enter the clamping groove 4, and the movable steel ball 10 and the positioning steel ball 9 are pressed to complete the locking.

[0043] Otherwise the disassembly process is as follows:

[0044] Hold and push the clamping ring 13. After the clamping ring 13 moves to the specified position, pull out the plug housing 2 backwards. The second inclined surface 7 on the boss 3 will push the movable steel ball 10 and the positioning steel ball 9 into the avoidance 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 take out the plug housing 2. At this time, the clamping 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 characteristics of the spring.
