Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and more specifically, to a quick blind-plug connector structure. Background Technology

[0002] With the rapid development of the server industry and the continuous increase in data center computing density, server liquid cooling systems, as core components ensuring stable equipment operation, face increasingly stringent requirements for performance and compatibility. Efficient liquid cooling solutions must balance heat dissipation efficiency, ease of installation, and system versatility. Quick-connect blind-fit connectors, as key connection components in the liquid cooling loop, directly impact the deployment flexibility and subsequent maintenance costs of the entire cooling system.

[0003] Currently, the widely used double-shutdown spring quick-connect fittings in the industry, while achieving bidirectional sealing during insertion and removal through built-in dual springs and meeting basic safety isolation requirements, have significant limitations in compatibility design. The female end structure of these fittings is highly bound to the matching parameters of the male end; a single female end fitting typically only fits one specific elasticity specification of male end fitting. Specifically, the spring force coefficient and other parameters inside the female end are fixed in design and cannot be adaptively adjusted according to the elastic characteristics of different male end fittings.

[0004] This single compatibility leads to many problems in practical applications: when the server liquid cooling system needs to replace the male connectors of different brands or models, the corresponding female connectors must be replaced at the same time, which not only increases the pressure on spare parts inventory, but also prolongs the time for system upgrades or repairs; at the same time, for complex liquid cooling scenarios that use a variety of male connectors, the insufficient compatibility of the female connectors will significantly reduce the flexibility of system deployment and make it difficult to meet diverse application needs. Utility Model Content

[0005] The technical problem to be solved by this application is the poor compatibility and high replacement cost caused by the elastic parameter binding of the female and male ends of the traditional blind-mating connector. In order to overcome the above defects of the prior art, this application provides a quick blind-mating connector structure.

[0006] This application provides a quick-connect blind-mating connector structure, including:

[0007] A male connector includes a first tube body, a first spring, and a valve core. The first tube body has a first inlet hole and a first outlet hole at its two ends, respectively. The valve core is coaxially movably disposed inside the first tube body. The outer diameter of the valve core is smaller than the inner diameter of the tube wall of the first tube body. The first spring is installed inside the first tube body and is used to drive the valve core to move toward the first outlet hole. The valve core has a sealing part, and the inner wall of the first outlet hole has a sealing ring. The valve core seals the sealing part inside the sealing ring by means of the first spring.

[0008] The female connector includes a second tube body, a valve stem, and a duckbill valve. The two ends of the second tube body are respectively provided with a second inlet hole and a second outlet hole. The second inlet hole allows the first tube body to be coaxially inserted into the inside of the second tube body. The valve stem is fixedly installed inside the second tube body and is used to press against the sealing part. The outer diameter of the valve stem is smaller than the inner diameter of the second tube body wall. The duckbill valve includes an integrally formed ring and a duckbill head. The ring is fixed to the inner wall of the second tube body and is positioned towards the valve stem. The duckbill head is positioned towards the second outlet hole.

[0009] When the first tube is inserted into the second tube, the valve stem presses against the sealing part, the first spring is compressed, and the sealing part is disengaged from the sealing ring, so that the liquid in the first tube flows out from the second outlet hole through the sealing ring and the duckbill valve in sequence.

[0010] Compared with existing technologies, the quick-connect blind-mating connector structure disclosed in this application has the following advantages: This quick-connect blind-mating connector structure achieves rapid opening and closing of the liquid passage during insertion and removal through the cooperation of the male valve core and the female valve stem. When not inserted, the male end achieves bidirectional sealing through the cooperation of the valve core's sealing part and the sealing ring, while the female end achieves sealing through the duckbill valve, effectively preventing liquid leakage and ensuring system safety. During insertion, the valve stem presses against the sealing part, opening the male end passage, allowing liquid to flow out sequentially through the sealing ring and the duckbill valve, ensuring smooth liquid flow and meeting the liquid transfer requirements of scenarios such as liquid cooling systems. The structural design overcomes the limitation of the highly bound elastic parameters of the female and male ends in the traditional double-shutdown spring structure, improving the connector's compatibility and eliminating the need to replace the female end simultaneously when replacing the male end.

[0011] In one possible implementation, the second tube body has a first fixing seat inside for fixing the valve stem. The outer peripheral wall of the first fixing seat is fixedly fitted to the inner wall of the second tube body, and the first fixing seat has a liquid outlet channel. Compared with the prior art, fixing the valve stem with the first fixing seat enhances the installation stability of the valve stem in the second tube body, preventing the valve stem from shaking or shifting during liquid flow or connector insertion and removal, and ensuring accurate pressure against the sealing part during insertion. The liquid outlet channel on the first fixing seat ensures that the liquid flowing in from the male end can smoothly pass through the internal structure of the female end, avoiding obstruction of liquid flow due to fixing the valve stem and ensuring smooth liquid transmission.

[0012] In one possible implementation, a second spring is also installed inside the second tube body. One end of the second spring is connected to the second tube body, and the other end of the second spring abuts against the ring, thereby pressing the ring against the first fixed seat. Compared with the prior art, the second spring, by abutting against the ring, ensures that the ring is tightly pressed against the first fixed seat, enhancing the installation firmness of the duckbill valve, preventing displacement of the duckbill valve under the influence of liquid pressure or insertion / removal actions, and ensuring stable sealing and flow functions. The elastic force of the spring can form a continuous preload on the duckbill valve, improving the sealing effect of the duckbill valve when not inserted, and further reducing the risk of liquid leakage.

[0013] In one possible implementation, the first pipe body is connected to an inlet pipe near the first inlet port, and the second pipe body is connected to an outlet pipe near the second outlet port. Temperature and pressure sensors are installed on both the inlet and outlet pipes. Compared to existing technologies, the temperature and pressure sensors on the inlet and outlet pipes can monitor the temperature and pressure parameters of the liquid in real time, allowing operators to promptly grasp the fluid status in pipelines such as the liquid cooling system. Monitoring data can quickly determine whether the system is operating normally, detect anomalies early, facilitate timely troubleshooting, ensure stable and reliable system operation, and reduce maintenance costs.

[0014] In one possible implementation, the inlet pipe is detachably connected to the first pipe body via a threaded structure; the outlet pipe is detachably connected to the second pipe body via a threaded structure. Compared with the prior art, the detachable connection between the inlet pipe and the first pipe body, and the outlet pipe and the second pipe body via threaded structures, facilitates the installation, disassembly, and replacement of the pipes; when the pipes are damaged or need to be replaced with pipes of different specifications, there is no need to replace the entire joint structure, reducing maintenance difficulty and cost, and improving the versatility and maintainability of the equipment.

[0015] In one possible implementation, a second fixing seat is provided inside the first tube body. The second fixing seat is used to fix the end of the first spring away from the valve core. The second fixing seat is fixed to the inner wall of the first tube body and has a liquid inlet channel. Compared with the prior art, the second fixing seat provides stable fixed support for the first spring, ensuring that the first spring will not deviate or tilt during the extension and contraction process, ensuring that it can stably drive the valve core to move towards the first liquid outlet, and ensuring the reliable sealing and opening functions of the valve core; the liquid inlet channel on the second fixing seat ensures that the liquid can flow smoothly from the first liquid inlet into the first tube body, avoiding the impact of fixing the spring on the liquid flow and ensuring the smoothness of liquid transmission.

[0016] In one possible implementation, a sealing ring is provided on the outer peripheral wall of the sealing portion, and the sealing ring fits against the inner wall of the sealing ring. Compared with the prior art, the sealing ring on the outer peripheral wall of the sealing portion fits against the inner wall of the sealing ring, which enhances the sealing performance when the male end is not inserted, further reduces the possibility of liquid leakage from the gap between the sealing portion and the sealing ring, improves the sealing reliability of the joint, and is suitable for scenarios such as liquid cooling systems with high sealing requirements.

[0017] In one possible implementation, the inner wall of the second inlet hole is provided with a snap-fit ​​ball; the outer wall of the first tube is provided with an annular groove that engages with the snap-fit ​​ball; a sliding sleeve is fitted around the outside of the second tube, the sliding sleeve having a clearance area, and a third spring is provided between the sliding sleeve and the second tube; driven by the third spring, the sliding sleeve slides to the mating end of the second tube, pressing the snap-fit ​​ball into the annular groove; an annular clamp is provided on the outer peripheral wall of the second tube, the annular clamp being used to prevent the sliding sleeve from dislodging from the second tube. Compared with the prior art, the engagement of the snap-fit ​​ball and the annular groove, as well as the pressing action of the sliding sleeve driven by the third spring, achieve a firm connection after the male and female connectors are inserted, preventing the connector from accidentally falling off due to external forces such as vibration and pulling during use, thus ensuring connection stability; the design of the sliding sleeve makes the insertion and removal of the connector convenient, simply sliding the sliding sleeve to release the pressing of the snap-fit ​​ball, facilitating quick separation of the connector, improving the efficiency of installation and maintenance, and meeting the needs of quick blind insertion.

[0031] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] See Figures 1 to 8This application discloses a quick-connect blind-fit connector structure, including: a male connector 1 and a female connector 2. The male connector 1 includes a first tube body 11, a first spring 12, and a valve core 13. The first tube body 11 has a first inlet hole 111 and a first outlet hole 112 at its two ends, respectively. The valve core 13 is coaxially movably disposed inside the first tube body 11. The outer diameter of the valve core 13 is smaller than the inner diameter of the tube wall of the first tube body 11. The first spring 12 is installed inside the first tube body 11 and is used to drive the valve core 13 to move toward the first outlet hole 112. The valve core 13 has a sealing part 131, and the inner wall of the first outlet hole 112 has a sealing ring 14. The valve core 13 seals the sealing part 131 in the sealing ring 14 by the first spring 12. The female connector 2 includes a second tube body 21, a valve stem 22, and a duckbill valve 23. The second tube body 21 has a second inlet hole 211 and a second outlet hole 23 at its two ends, respectively. The first tube 11 is coaxially inserted into the second tube 21 through a liquid inlet 212 and a second liquid inlet 211. A valve stem 22 is fixedly installed inside the second tube 21 and is used to press against the sealing part 131. The outer diameter of the valve stem 22 is smaller than the inner diameter of the tube wall of the second tube 21. The duckbill valve 23 includes an integrally formed ring 231 and a duckbill head 232. The ring 231 is fixed to the inner wall of the second tube 21 and is positioned towards the valve stem 22. The duckbill head 232 is positioned towards the second liquid outlet 212. When the first tube 11 is inserted into the second tube 21, the valve stem 22 presses against the sealing part 131, the first spring 12 is compressed, and the sealing part 131 is disengaged from the sealing ring 14, so that the liquid in the first tube 11 flows out from the second liquid outlet 212 through the sealing ring 14 and the duckbill valve 23 in sequence.

[0033] In the male connector 1, the first tube body 11 is a hollow cylindrical structure, and the material can be corrosion-resistant engineering plastic. The first inlet hole 111 and the first outlet hole 112 are located at the two ends of the first tube body 11 and are connected to the internal cavity of the first tube body 11 for liquid inflow and outflow. The valve core 13 is cylindrical, and its outer diameter is smaller than the inner diameter of the tube wall of the first tube body 11 to ensure that the valve core 13 can move smoothly coaxially inside the first tube body 11 and facilitate the flow of liquid between the valve core 13 and the tube wall. The sealing part 131 on the valve core 13 is integrally formed with the valve core 13. The sealing ring 14 is an inwardly protruding annular structure on the inner wall of the first outlet hole 112, and its inner diameter matches the outer diameter of the sealing part 131. When the sealing part 131 is pushed into the sealing ring 14 by the first spring 12, it can effectively prevent liquid from flowing out of the first outlet hole 112.

[0034] In the female connector 2, the second tube 21 is also a cylindrical hollow structure. The diameter of the second liquid inlet 211 matches the outer diameter of the first tube 11 so that the first tube 11 can be coaxially inserted into the second tube 21. The valve stem 22 is a cylindrical rod-shaped structure. One end is fixedly installed at the center of the second tube 21, and the other end faces the second inlet hole 211. When the first tube 11 is inserted into the second tube 21, the valve stem 22 can accurately press against the sealing part 131 of the valve core 13. The outer diameter of the valve stem 22 is smaller than the inner diameter of the second tube 21, so that the liquid can flow in the gap between the valve stem 22 and the tube wall. The ring 231 of the duckbill valve 23 is an annular structure and is fixed to the inner wall of the second tube 21, with one side of the ring 231 facing the valve stem 22. The duckbill head 232 is a duckbill-shaped structure made of elastic material, with its free end facing the second outlet hole 212. When there is no liquid flow, the duckbill head 232 closes due to its own elasticity, thereby sealing the female end connector 2 and preventing liquid from flowing out of the second inlet hole 211.

[0035] In this embodiment, the second tube 21 is provided with a first fixing seat 3 for fixing the valve stem 22. The outer peripheral wall of the first fixing seat 3 is fixedly attached to the inner wall of the second tube 21, and the first fixing seat 3 is provided with a liquid outlet channel 31.

[0036] Specifically, the first fixed seat 3 has a disc-shaped structure, and its outer peripheral wall is fixedly fitted to the inner wall of the second tube 21 to ensure that the first fixed seat 3 will not move or loosen inside the second tube 21. The end of the valve stem 22 away from the pressure sealing part 131 is fixedly connected to the center position of the first fixed seat 3 to ensure the stability and coaxiality of the valve stem 22. The liquid outlet channel 31 on the first fixed seat 3 consists of multiple through holes evenly distributed around the valve stem 22. These through holes penetrate both sides of the first fixed seat 3, allowing the liquid to flow smoothly from one side of the first fixed seat 3 to the other side, that is, from the side near the second liquid inlet 211 to the side near the second liquid outlet 212.

[0037] In this embodiment, a second spring 4 is also installed inside the second tube 21. One end of the second spring 4 is connected to the second tube 21, and the other end of the second spring 4 abuts against the ring 231, so as to press the ring 231 against the first fixed seat 3.

[0038] Specifically, one end of the second spring 4 abuts against the inner wall of the second tube 21 near the second liquid outlet 212, and the other end abuts against the ring 231 of the duckbill valve 23. In its natural state, the second spring 4 is in a compressed state, and its own elastic force presses the ring 231 tightly against the first fixed seat 3, ensuring the sealing performance between the ring 231 and the first fixed seat 3 and preventing liquid leakage between them.

[0039] In this embodiment, the first tube 11 is connected to an inlet pipe 5 on the side near the first inlet hole 111, and the second tube 21 is connected to an outlet pipe 6 on the side near the second outlet hole 212. Temperature and pressure sensors 7 are installed on both the inlet pipe 5 and the outlet pipe 6.

[0040] Specifically, the inlet pipe 5 is connected to the side of the first pipe body 11 near the first inlet hole 111, and the outlet pipe 6 is connected to the side of the second pipe body 21 near the second outlet hole 212. The materials of the inlet pipe 5 and the outlet pipe 6 can be selected according to the properties of the liquid being transported, such as plastic pipes. Temperature and pressure sensors 7 are installed on the inlet pipe 5 and the outlet pipe 6 respectively, with the sensor's detection end extending into the pipe, enabling real-time detection of the temperature and pressure of the liquid inside the pipe. The temperature and pressure sensors 7 can transmit the detected data to the control system via a wired connection, allowing operators to monitor the liquid's condition in real time, promptly detect abnormalities, and take appropriate action. When the temperature and pressure sensors 7 are no longer needed, they can be replaced with a plug.

[0041] In this embodiment, the inlet pipe 5 is detachably connected to the first pipe body 11 via a threaded structure; the outlet pipe 6 is detachably connected to the second pipe body 21 via a threaded structure.

[0042] Specifically, the end of the inlet pipe 5 is provided with an internal thread, and the end of the first pipe body 11 near the first inlet hole 111 is provided with an external thread that matches the internal thread of the inlet pipe 5. The inlet pipe 5 is screwed to the first pipe body 11 through the threaded structure, realizing a detachable connection between the two, which facilitates the replacement and maintenance of the inlet pipe 5. Similarly, the end of the outlet pipe 6 is provided with an external thread, and the end of the second pipe body 21 near the second outlet hole 212 is provided with a corresponding internal thread. The outlet pipe 6 is detachably connected to the second pipe body 21 through the threaded structure. To ensure the sealing of the threaded connection, a sealing O-ring can be installed at the threaded connection.

[0043] In this embodiment, a second fixing seat 8 is provided inside the first tube body 11. The second fixing seat 8 is used to fix the end of the first spring 12 away from the valve core 13. The second fixing seat 8 is fixed to the inner wall of the first tube body 11. The second fixing seat 8 is provided with a liquid inlet channel 81.

[0044] Specifically, the second fixing seat 8 is a disc-shaped structure, which is fixed to the inner wall of the first tube 11 near the first liquid inlet hole 111. The end of the first spring 12 away from the valve core 13 is sleeved on the second fixing seat 8 or abuts against the second fixing seat 8, thereby fixing the first spring 12 and ensuring that the first spring 12 can stably apply elastic force to the valve core 13. The liquid inlet channel 81 on the second fixing seat 8 consists of multiple evenly distributed through holes. These through holes penetrate both sides of the second fixing seat 8, allowing liquid to enter the interior of the first tube 11 from the first liquid inlet hole 111 through the liquid inlet channel 81 and flow towards the valve core 13.

[0045] In this embodiment, a sealing ring 9 is provided on the outer peripheral wall of the sealing part 131, and the sealing ring 9 is in contact with the inner wall of the sealing ring 14.

[0046] Specifically, the outer peripheral wall of the sealing part 131 is provided with an annular groove 132, and the sealing ring 9 is installed in the groove 132. The sealing ring 9 can be made of elastic materials such as rubber. When the sealing part 131 is sealed in the sealing ring 14, the sealing ring 9 is compressed and fits tightly against the inner wall of the sealing ring 14, further enhancing the sealing effect of the male connector 1 and preventing liquid leakage when not inserted.

[0047] In this embodiment, the sealing ring 14 is provided with a retaining ring 15, which is used to prevent the sealing part 131 from coming out of the first tube 11.

[0048] Specifically, the retaining ring 15 on the sealing ring 14 is an inwardly protruding annular structure. When the first spring 12 drives the valve core 13 to move toward the first liquid outlet 112, the retaining ring 15 can block the sealing part 131, preventing the sealing part 131 from moving excessively and coming out of the first tube 11, thus ensuring the normal operation of the valve core 13 inside the first tube 11.

[0049] In this embodiment, the inner wall of the second liquid inlet 211 is provided with a snap-fit ​​ball 10; the outer wall of the first tube 11 is provided with an annular groove 113 that engages with the snap-fit ​​ball 10; a sliding sleeve 20 is sleeved on the outside of the second tube 21, the sliding sleeve 20 is provided with a clearance area 201, and a third spring 30 is provided between the sliding sleeve 20 and the second tube 21; under the drive of the third spring 30, the sliding sleeve 20 slides to the mating end of the second tube 21 and presses the snap-fit ​​ball 10 into the annular groove 113; an annular clamp 40 is provided on the outer peripheral wall of the second tube 21, and the annular clamp 40 is used to prevent the sliding sleeve 20 from coming off the second tube 21.

[0050] Specifically, the inner wall of the second inlet hole 211 is provided with multiple evenly distributed mounting holes, and the snap-fit ​​ball 10 is installed in the mounting holes, with some of the ball protruding from the inner wall of the second inlet hole 211. The outer wall of the first tube 11 is provided with an annular groove 113 that matches the snap-fit ​​ball 10. When the first tube 11 is inserted into the second tube 21, the snap-fit ​​ball 10 can be snapped into the annular groove 113, realizing the initial fixation of the male end connector 1 and the female end connector 2. The sliding sleeve 20 sleeved on the outside of the second tube 21 is a cylindrical structure, and its inner wall matches the outer wall of the second tube 21, allowing it to slide along the axial direction of the second tube 21. The clearance area 201 on the sliding sleeve 20 is a region with a large inner diameter. When the sliding sleeve 20 slides to the position corresponding to the clearance area 201 and the snap-fit ​​ball 10, the snap-fit ​​ball 10 can move outward, facilitating the insertion or removal of the first tube 11. A third spring 30 is sleeved on the second tube 21 between the sliding sleeve 20 and the second tube 21. One end of the spring 30 abuts against the sliding sleeve 20, and the other end abuts against a protrusion on the second tube 21. In its natural state, the third spring 30 drives the sliding sleeve 20 to slide to the mating end of the second tube 21. At this time, the inner wall of the sliding sleeve 20 presses the locking ball 10 into the annular groove 113 of the first tube 11, so that the male end connector 1 and the female end connector 2 are firmly connected. At the same time, the annular clamp 40 is set to prevent the sliding sleeve 20 from coming off the second tube 21. When it is necessary to pull out the first tube 11, the sliding sleeve 20 is slid away from the mating end, compressing the third spring 30 so that the clearance area 201 corresponds to the locking ball 10. The locking ball 10 is no longer squeezed, and the first tube 11 can be pulled out.

[0051] This embodiment presents a quick-connect blind-fit connector structure. When not connected, the male end drives the valve core 13 via the first spring 12, causing the sealing part 131 to fit against the sealing ring 14 to achieve a seal; the female end duckbill valve 23 closes due to its own elasticity, forming a bidirectional seal to prevent leakage. When connected, the first tube 11 is inserted into the second tube 21, the female end valve stem 22 presses against the male end sealing part 131, compressing the first spring 12, causing the sealing part 131 to disengage from the sealing ring 14, and the male end channel opens; liquid flows from the first tube 11 through the sealing ring 14 into the female end, pushing the duckbill head 232 of the duckbill valve 23 to open, and finally flows out from the second outlet hole 212.

[0052] The beneficial effects of this application include:

[0053] I. Enhanced Compatibility and Versatility: Overcoming the limitation of traditional double-shutdown spring connectors where the elastic parameters of the female and male ends must be strictly matched. Through the structural design of independent sealing of the male end valve core 13 spring and independent sealing of the female end duckbill valve 23, the female end connector 2 can be adapted to male end connectors 1 of different brands or elastic specifications without the need for simultaneous replacement of the female end, significantly reducing spare parts inventory and maintenance costs, and meeting the needs of complex liquid cooling systems for multiple specifications.

[0054] II. Achieving reliable bidirectional sealing: When not inserted, the male end relies on the first spring 12 to drive the valve core 13 to tightly fit the sealing part 131 against the sealing ring 14 to achieve sealing; the female end relies on the elastic closure of the duckbill valve 23 to achieve sealing, forming a bidirectional independent sealing mechanism, effectively preventing liquid leakage and ensuring system safety.

[0055] III. Secure Connection and Convenient Operation: The inner wall of the second liquid inlet hole 211 on the female end is equipped with a retaining ball bearing 10, and the outer wall of the male end is equipped with a corresponding annular groove 113, which works in conjunction with the sleeve 20 and the third spring 30. After insertion, the spring drives the sleeve 20 to press the ball bearing into the annular groove 113, ensuring a secure connection and preventing it from falling off due to external forces; when separation is required, the sleeve 20 releases the ball bearing for quick removal, meeting the needs of blind insertion and improving maintenance efficiency.

[0056] IV. Structural Stability and Smooth Flow: Both the male and female ends are equipped with fixed seats to stably support the first spring 12 and the valve stem 22 respectively, ensuring accurate movement of the valve core 13 and precise positioning of the valve stem 22; the inlet / outlet channels 31 on the fixed seats are designed to ensure unobstructed flow of liquid. The female end is equipped with a second spring 4 to pre-tighten the duckbill valve 23 ring 231, enhancing its sealing performance and installation stability.

[0057] V. Facilitates Monitoring and Maintenance: The inlet pipe 5 and outlet pipe 6 are detachably connected to the connector pipe body via a threaded structure, facilitating the replacement of pipes or components and reducing maintenance difficulty and cost. Temperature and pressure sensors 7 are installed on the pipes to monitor the fluid status in real time, aiding in system operation monitoring and fault early warning.
