Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to pipeline connection technology, specifically a floating male head structure for a blind-mating liquid connector. Background Technology

[0002] When optical modules transmit signals quickly and efficiently, they generate a large amount of heat. If this heat accumulates and cannot dissipate, it can easily damage electronic components. Therefore, timely heat dissipation is necessary to ensure operation within a reasonable temperature range. Tiny optical module components utilize matching miniature liquid coolers. The cooling pipe connections employ liquid connectors, which have male and female connectors that interlock to create a channel, allowing the heat dissipation medium to flow smoothly. For example, patent document CN213871607U discloses a blind-mating fluid connector. When the plug and socket are connected, external force causes the front end of the second valve sleeve to extend into the first valve sleeve, pushing the first valve core backward. The first valve core compresses the first spring. Simultaneously, the front end of the inner core extends into the second valve sleeve, pushing the second valve core backward. The second valve core compresses the second spring, thus connecting the plug and socket. That is, the first through hole, first flow channel, first valve sleeve, second flow channel, second valve sleeve, second through hole, and third through hole are connected. However, in actual installation, when the male and female connectors are mated, due to the cumulative tolerances in the assembly and manufacturing of the workpieces, there is an angle between the axes of the male and female connectors, making it impossible to accurately align them. If the force is too great or too fast, the stress generated by the mating collision in various directions can easily be dispersed to the precision equipment, leading to damage to the precision equipment or even coolant leakage. Utility Model Content

[0003] The purpose of this invention is to provide a floating male head structure for a blind-mating liquid connector, which solves the technical problem in the prior art where the axes of the male and female heads are angled and cannot be accurately coaxially connected.

[0004] This utility model provides a floating male connector structure for a blind-mating liquid connector, including a male connector body. The male connector body has a male connector connector attached to its rear end. A male connector base is fitted onto the rear of the male connector connector. A circumferential gap is provided between the inner wall of the male connector base and the outer wall of the male connector connector. A first limiting ring and a second limiting ring are respectively provided on the front and rear sides of the male connector base on the outer wall of the male connector connector. At least two notches are provided on the end face of the first limiting ring along the circumferential direction. The end face of the male connector base has protrusions equal in number to the notches, and the protrusions are correspondingly arranged in the notches. Gaps are provided between the protrusions and the notches in both the axial and circumferential directions. A sealing ring is provided between the inner wall of the male connector base and the outer wall of the male connector connector. Mounting grooves that mate with the sealing ring are provided in both the inner wall of the male connector base and the outer wall of the male connector connector. An external thread is provided on the rear outer wall of the male connector base.

[0005] Furthermore, the second limiting ring is a snap ring.

[0006] Furthermore, the axial cross-section of the notch is semi-circular.

[0007] Compared with existing technologies, the advantages of this invention are positive and significant. When the male connector is inserted into the female connector, the male connector's axis coincides with the female connector's axis, while the male connector base is restrained by another device and continues to maintain its original axial direction. This causes the axis of the male connector's axis to form an angle with the axis of the male connector base. The two devices continue to connect and advance until the male connector is fully inserted into the female connector, successfully connecting the pipes of the two devices. This reduces the stress caused by the misalignment of the male and female connectors during insertion, thus reducing damage to precision equipment. Attached Figure Description

[0013] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0014] like Figures 1-5As shown, this utility model provides a floating male connector structure for a blind-mating liquid connector, including a male connector 1, a male connector body 2, a male connector connector 3 connected to the rear end of the male connector body 2, a male connector base 4 sleeved on the rear part of the male connector connector 3, a circumferential gap between the inner wall of the male connector base 4 and the outer wall of the male connector connector 3, and a first limiting ring 5 and a second limiting ring 6 respectively provided on the front and rear sides of the male connector base 4 on the outer wall of the male connector connector 3. At least two notches 7 are provided along the circumferential direction. The end face of the male base 4 is provided with a number of protrusions 8 equal to the number of notches 7. The protrusions 8 are provided in the notches 7 one by one. There are gaps between the protrusions 8 and the notches 7 in both the axial and circumferential directions. A sealing ring 9 is provided between the inner wall of the male base 4 and the outer wall of the male connector 3. There are mounting grooves in the inner wall of the male base 4 and the outer wall of the male connector 3 that mate with the sealing ring 9. An external thread 10 is provided on the outer wall of the rear end of the male base 4.

[0015] Furthermore, the second limiting ring 6 is a retaining ring.

[0016] Furthermore, the axial cross-section of the notch 7 is semi-circular.

[0017] Specifically, the specific structure and principle of the male head body 2 and the snap ring in this utility model, as well as other aspects not described in detail, all adopt well-known solutions in the prior art, which are already understood by those skilled in the art and will not be repeated here.

[0018] The working principle of this utility model:

[0019] The male connector 1 and female connector 11 of this utility model are used together. The male connector body 2 is also provided with a male connector valve core inside, and a male connector spring is provided between the male connector valve core and the male connector body 2. The female connector 11 includes a female connector body, and a female connector valve core is provided inside the female connector body. A female connector spring is provided between the female connector valve core and the female connector body. The male connector valve core, the male connector spring, and the female connector 11 are all known structures in the prior art.

[0020] The gaps between the male connector 3 and the male base 4, as well as the gaps between the protrusion 8 and the notch 7, allow the male connector 3 to swing and float within the male base 4, which in turn supports the male connector 3. The engagement of the protrusion 8 and the notch 7 also prevents circumferential rotation between the male connector 3 and the male base 4. Tightening the external thread 10 of the male base 4 simultaneously rotates the male connector 3. The sealing ring 9 not only seals against leakage but also maintains the appropriate gap between the male connector 3 and the male base 4, absorbing stress from multiple directions. The second limiting ring 6 prevents the male connector 3 from detaching from the male base 4.

[0021] In use, first connect one end of the female connector 11 to a device via a thread, then connect one end of the male connector 1 to another device via the external thread 10 of the male connector base 4. Then insert the other end of the male connector 1 into the other end of the female connector 11. When the male connector 1 is inserted into the female connector 11, the male connector 3 and the female connector 11 are aligned on the axis. The male connector base 4 is restrained by the other device and continues to maintain its original axis direction, so that the axis of the male connector 3 and the axis of the male connector base 4 form an angle. The two devices continue to be connected and pushed forward until the male connector 1 is fully inserted into the female connector 11, thus successfully connecting the pipes of the two devices. This reduces the stress caused by the misalignment of the male connector 1 and the female connector 11 during insertion, reducing damage to precision equipment.
