Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a fluid connector for a thermal management system. Background Technology

[0002] As electronic products generate increasingly more heat within a specified time, traditional fan cooling is no longer sufficient to meet heat dissipation requirements. Therefore, many devices utilize liquid cooling technology to improve equipment efficiency and stability, while also achieving energy savings and noise reduction. To enable rapid connection and disconnection between modules, fluid connectors are used for series connection. However, these connectors have several drawbacks: firstly, existing fluid connectors are prone to shaking during assembly and disassembly, leading to decreased installation accuracy; secondly, existing connectors have complex structures, numerous assembly and disassembly steps, and complex maintenance, relying heavily on worker expertise, resulting in low assembly efficiency and prolonged maintenance time.

The inner wall of the middle section of the sleeve is provided with an inner stepped positioning shoulder. In the natural state, the first transverse spring causes the inner stepped positioning shoulder to press against the outer stepped positioning shoulder of the transition section.

[0015] Alternatively, the outer wall of the sleeve may also be provided with a gripping section having several grooves.

[0016] In some embodiments, the female seat includes a seat housing, a support rod coaxially disposed within the seat housing, and a first valve core slidably connected to the inner wall of the seat housing.

The rear end of the sheath 3 is elastically damped and slides to connect to the middle section of the housing 1, and its front locking ring 31 is located outside the connecting ring 11. In its natural state, the guide pressing slope 32 on the inner wall of the locking ring 31 fits against the outer spherical body 51. The locking elements 4 are radially slidably connected to the inner radial guide hole 12 of the connecting ring 11. The locking elements 4 are preferably spheres. The middle column 50 of the unlocking element 5 is radially slidably connected to the outer radial guide hole 13 of the connecting ring 11, and its two ends of the spherical bodies 51 are exposed at both ends of the outer radial guide hole 13. The unlocking element 5 is preferably an ellipsoidal sphere, and the spherical bodies 51 are hemispherical.

[0035] The male head 01 is inserted into the locking female seat 02. The head shell 2 extends into the inner cavity of the seat shell 1. The guide support inclined surface 21 first contacts the inner end spherical body 51, causing the unlocking part 5 to move radially outward. As a result, the outer end spherical body 51 pushes the protective sleeve 3 to slide backward. The locking part 4 then rolls and fits against the locking ring 31 and the locking platform 20 until it is locked. Pulling the protective sleeve 3 with one hand can separate the male head 01 and the female seat 02.

[0036] This fluid connector for thermal management systems features a novel locking connection part 03. It employs a specially structured unlocking element 5 and a locking element 4 to achieve stable, wobbly, and rapid assembly and disassembly. Its advantages are: firstly, the fluid connection area ensures stable assembly and disassembly without wobbling, resulting in high assembly and product precision; secondly, its simple structure facilitates assembly and maintenance, allowing for single-handed insertion and removal, leading to high assembly efficiency and minimal maintenance time; and thirdly, the combination of the guide support slope 21 and the guide clamping slope 32 facilitates rapid and jam-free insertion.

Its advantages are: the structure is simple and easy to connect.

[0038] Furthermore, the outer wall of the locking platform 20 and the connecting ring 11 are fitted with a small clearance. The rear end of the locking platform 20 is provided with a chamfered locking bevel 22, and the rear end of the locking bevel 22 is provided with a receiving ring groove 23. The beneficial effect is that this setting ensures smooth installation without jamming.

[0039] Furthermore, the housing 1 includes a circular tube seat 10, the inner hole of the seat 10 and the head shell 2 are fitted with the same diameter. The seat 10 and the connecting ring 11 are integrally connected to both ends of the transition section of the hollow frustum structure. The inner wall of the transition section is a chamfered locking stop surface 17. The locking stop surface 17 and the guide support inclined surface 21 have the same structure. When the male head 01 is inserted into the locking female seat 02, the locking stop surface 17 fits against the guide support inclined surface 21. Its beneficial effect is that this setting can improve the installation accuracy.

[0040] Furthermore, the sheath 3 includes an annular sleeve 30 that is gap-connected to the seat 10. A large-diameter locking ring 31 is integrally connected to the front end of the sleeve 30. The inner wall of the middle section of the sleeve 30 is provided with an inner stepped positioning shoulder 33, and the outer wall of the transition section is provided with an outer stepped positioning shoulder 14. In the natural state, the first transverse spring 030 elastically extends to press the inner stepped positioning shoulder 33 tightly against the outer stepped positioning shoulder 14. The inner wall of the rear end shoulder of the inner stepped positioning shoulder 33 slides against the outer wall of the seat 10. The first transverse spring 030 is transversely located in the gap cavity between the sleeve 30 and the seat 10, and the rear end shoulder and the support rod seat 7 of the female seat 01 are respectively attached to the front and rear ends of the first transverse spring 030.

[0041] Preferably, the outer wall of the sleeve 30 is also provided with a gripping section 34, which has grooves to increase friction. The advantage of this is that the gripping section 34 facilitates operation and disassembly.

[0042] Furthermore, the female seat 01 includes a seat housing 1, a support rod 8 coaxially disposed in the inner cavity of the seat housing 1, and a first valve core 6 slidably connected to the inner wall of the seat housing 1.

An outer annular opening is formed between the front positioning block 82 of the support rod 8 and the seat body 10.

[0043] The rear end ring of the first valve core 6 is slidably connected to the inner wall of the seat 10, and a second transverse spring 010 is provided between it and the rear positioning block 81.
