Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of liquid cooling piping systems, and specifically relates to a connector that can accommodate positional deviations. Background Technology
[0002] Liquid cooling piping connections widely utilize quick-connect devices, whose main structure consists of two key parts: a male end and a female end. In actual industrial applications, the male and female ends need to be installed and fixed to different components. However, due to limitations in manufacturing processes, these components inevitably have certain manufacturing tolerances during production. These tolerances directly cause positional deviations between the male and female ends when they are mated, such as axial offset or angular tilt.
[0003] When there is such a positional deviation between the male and female ends, it will seriously hinder the insertion and assembly process between them. In traditional connection methods, if the insertion operation is forced, the precision structure inside the connecting device, such as the valve core, sealing ring, and the fit between various housings, will be damaged. The valve core may deform due to uneven stress, the sealing ring may be squeezed and misaligned, resulting in loss of sealing performance, and various housings may also crack or wear. This will not only prevent the connecting device from working properly, but may also cause leakage in the liquid cooling pipeline, thus posing a huge threat to the stability and safety of the entire liquid cooling system. Summary of the Invention
[0004] To address the aforementioned shortcomings in the existing technology, the present invention provides a connector that can accommodate positional deviations, thereby solving problems such as deformation of the valve core due to uneven force, possible misalignment of the sealing ring due to compression, loss of sealing performance, and potential cracking or wear of various housings.

[0029] Example
[0030] like Figures 1-4 As shown, a connector capable of accommodating positional deviations includes a male end A and a female end B. The male end A and the female end B are plugged into each other. The female end B includes an upper female end housing 1, a lower female end housing 2, a female end sleeve 3, and a female end valve body C. The upper female end housing 1 and the lower female end housing 2 are detachably connected. The female end valve body C is installed inside the upper female end housing 1 and the lower female end housing 2. A female end outer sealing ring 12 is installed at the connection between the upper female end housing 1 and the lower female end housing 2. The male end A includes an upper male end housing 13, a lower male end housing 14, a upper male end housing locking nut 15, an upper male end housing locking sleeve 16, and a male end locking cover 17. The upper male end housing 13 is detachably connected to the lower male end housing 14 through the upper male end housing locking nut 15. The upper male end housing locking sleeve 16 is detachably connected to the upper male end housing locking nut 15. The male end locking cover 17 is detachably connected to the upper male end housing 13. A male end valve body D is provided inside the upper male end housing 13.
[0031] The female valve body C includes a female valve core 4, a female return spring 10, and a female valve stem 11. The female valve core 4 is installed on the upper end of the female return spring 10, and the female return spring 10 is installed on the upper part of the female valve stem 11. A female connection sealing ring 6 is provided on the upper part of the female valve core 4, and a female inner sealing ring 7 is provided on the lower part of the female connection sealing ring 6. A female isolation ring 8 is provided between the female connection sealing ring 6 and the female inner sealing ring 7. A female valve core sealing ring 9 is provided on the top of the female valve stem 11, and a female color identification ring 5 is provided on the outside of the female end B.
[0032] The male valve body D includes a male valve core 20, a male return spring 22, a male anti-reverse snap ring 25, and a male spring support seat 26. The male valve core 20 is installed at the bottom of the male return spring 22, the male anti-reverse snap ring 25 is installed at the top of the male return spring 22, and the male spring support seat 26 is installed between the male anti-reverse snap ring 25 and the male return spring 22. The male upper housing 13 is provided with a male upper housing sealing ring 18, the outer ring of the male valve core 20 is provided with a male valve core sealing ring 21, the male lower housing 14 and the male upper housing locking sleeve 16 are provided with a male correction sealing ring 19, the outside of the male upper housing 13 is provided with a male color identification ring 23, the top of the male lower housing 14 is provided with a male outer sealing ring 24, and the top of the male upper housing 13 is a ball head structure.
[0033] When there are positional, coaxial, or angular deviations between male terminal A and female terminal B, the ball joint structure of the upper housing 13 of the male terminal can offset radially or rotate around its center to automatically absorb the positional deviation. This structural design enables the connector to still connect and work normally even when there are certain installation deviations between male terminal A and female terminal B, ensuring the reliability and stability of the connection.
[0034] When male terminal A and female terminal B are disconnected, the end face of male terminal A and the end face of the valve core inside female terminal B are separated and no longer in contact. Similarly, the valve core inside male terminal A and the central support end face of the lower housing of female terminal B are also separated and no longer in contact. Instead, they contact their respective sealing ring structures to prevent fluid leakage and achieve bidirectional rapid sealing and flow control. This indicates that the connector can quickly achieve a seal through the sealing ring structure in the disconnected state, preventing fluid leakage.
[0035] The male and female return springs and anti-reverse snap rings are formed by winding, while the rest, except for the sealing ring, are machined or injection molded, which facilitates production.
[0036] The female end sub-assembly is formed by assembling the female end sub-parts with auxiliary equipment, and the male end sub-assembly is formed by assembling the male end sub-parts with auxiliary equipment. The male end sub-assembly and the female end sub-assembly are respectively installed and fixed with their respective matching parts, which reflects its modular assembly method and simplifies the assembly process.
[0037] Male end A and female end B are plugged into each other. When male end A and female end connector are in the connected state, the end face of male end A abuts against the end face of valve core inside female end connector, that is, the end face of male end valve core 20 abuts against the end face of the center support column of the lower housing of female end connector.
[0038] At this time, the male valve core 20 abuts against the end face of the female valve column 11 and disengages from the sealing ring structure that it is used for sealing. The sealing rings include the male upper housing sealing ring 18, the male valve core sealing ring 21, the male correction sealing ring 19, the male outer sealing ring 24, the female outer sealing ring 12, the female valve core sealing ring 9, the female connection sealing ring 6, and the female inner sealing ring 7, etc., to create a passage so that fluid can flow through.
[0039] When male end A and female end B are disconnected, the end face of male end A and the end face of female end valve column 11 are separated from each other and no longer abut against each other. Instead, they come into contact with their respective sealing ring structures to prevent fluid from overflowing and achieve bidirectional rapid sealing and flow interception.
[0040] By having the ball-shaped structure at the top of the male end upper housing 13 make active contact with the male end lower housing 14, the two independently separated pipelines are connected, and the positional deviation between the male end A and the female end B is automatically absorbed.

Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date.

Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention. These should also be considered within the scope of protection of the present invention, and will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
