Description

Technical Field

[0001] This invention relates to the field of liquid cooling fluid connection technology for data centers, and more particularly to a blind-mating fluid connector. Background Technology

[0002] In the field of data center liquid cooling, coolant delivery is typically required, and the delivery process necessitates on / off control, thus requiring appropriate fluid connectors. For example, Chinese Patent Publication No. CN114576455A discloses a pressurized plug-and-play fluid connector, including a female plug and a male plug. The female and male plugs are interlocked, and the opening and closing of the plug's valve core is controlled, thereby controlling the flow of fluid. Existing connectors generally require both male and female plugs, necessitating the manufacture of two types, which undoubtedly increases manufacturing costs. Therefore, there is an urgent need for a connector that requires only one type of plug for blind-mating control of fluid flow. Summary of the Invention

[0003] In view of this, the present invention provides a blind-mating fluid connector, which solves the technical problem in the prior art that requires the use of two different male and female plugs to achieve blind mating.

[0004] The technical means adopted in this invention are as follows: A blind-mating fluid connector, comprising:

[0005] The valve body has a hollow cavity.

[0006] A cover plate, which is fixedly connected to one end of the valve body.

[0007] A spring is located inside the valve body, with one end of the spring connected to the cover plate.

[0008] The first slide is fitted inside the valve body, and the other end of the spring is connected to one end of the first slide.

[0009] A pad is located at the other end of the valve body. The entire pad can slide into the hollow cavity in the valve body. The pad is connected to the first slide block by a fixing rod.

[0010] The second slide is located between the first slide and the pad, and the cover plate, the first slide, the second slide, and the pad are all provided with through holes.

[0011] A rotating valve core is rotatably mounted within a second slide. The rotating valve core includes a sealing plate for sealing the through-hole of the gasket. Under normal conditions, the sealing plate seals the through-hole of the gasket. When the gasket is compressed, it pushes the second slide to rotate the rotating valve core, thereby rotating the sealing plate and opening the through-hole of the gasket.

[0012] Preferably, the rotary valve core further includes a curved portion and a connecting portion. The second slide has a cut, and the cut has a transverse mounting hole that penetrates the second slide. The curved portion is located at the cut. The inner wall of the valve body located at the cut has a groove. The end of the curved portion extends into the groove. The connecting portion passes through the mounting hole. The sealing plate is installed below the connecting portion.

[0013] Preferably, the rotary valve core further includes a limiting part, which is located at one end of the connecting part and extends out of the second slide. A transverse sliding groove is provided on the inner wall of the valve body located at the limiting part, and the end of the limiting part is matched and inserted into the transverse sliding groove.

[0014] Preferably, the through hole of the second slide is convex in shape.

[0015] Preferably, the second slide is provided with a connecting hole, and the second slide passes through the connecting hole onto the fixing rod between the pad and the first slide.

[0016] Preferably, the end face of the sealing plate is provided with a protruding plug.

[0017] Preferably, a sealing ring is provided on the fixing rod between the first slide and the second slide.

[0018] Preferably, the cover plate is threaded to the end of the valve body.

[0019] Compared with the prior art, the blind-mating fluid connector provided by this invention only requires a single connector structure with pressure applied at both ends for blind mating to achieve automatic flow. When the pressure at both ends is released, the connector flow is quickly closed under the action of spring force, effectively reducing fluid leakage. Attached Figure Description

[0035] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0036] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, a blind-mating fluid connector includes:

[0037] Valve body 1 has a hollow cavity, that is, the overall shape of valve body 1 is cylindrical.

[0038] Cover plate 2 and cover plate 1 are fixedly connected to one end of valve body 1. In this embodiment, cover plate 1 is threadedly connected to the end of valve body 2.

[0039] Spring 3 is located inside valve body 1. One end of spring 3 is connected to cover plate 2. The coiled spring 3 is adjacent to the inner wall of valve body 1.

[0040] The first slide 4 and the first slide sleeve 4 are located inside the valve body 1. The overall shape of the first slide 4 is cylindrical and it is matched in the hollow cavity of the valve body 1. That is to say, the first slide 4 can slide relative to the hollow cavity of the valve body 1. The other end of the spring 3 is connected to one end of the first slide 4.

[0041] The pad 5 is located at the other end of the valve body 1. The overall shape of the pad 5 is also cylindrical. The pad 5 can slide into the hollow cavity in the valve body 1. The pad 5 is connected to the first slide block 4 by a fixing rod 7. There are about 4 to 5 fixing rods 7 distributed around the circumference of the pad 5.

[0042] The second slide 6 is located between the first slide 4 and the pad 5. The second slide 6 is also cylindrical in shape and can slide within the valve body 1. This embodiment provides a method for fixing the second slide 6 between the pad 5 and the first slide 4, such as... Figure 10 and Figure 11 As shown, specifically, the second slide 6 is provided with a connecting hole 61, and the second slide 6 passes through the connecting hole 61 onto the fixing rod 7 between the pad 5 and the first slide 4. In addition, it should be noted that in order to enable the connector as a whole to achieve passage, the cover plate 2, the first slide 4, the second slide 6, and the pad 5 mentioned above are all provided with through holes, and fluid can flow through the through holes of these components in the valve body 1.

[0043] Rotary valve core 8, which is rotatably mounted within the second slide 6, such as... Figure 12 As shown, the rotary valve core 8 includes a sealing plate 81 for sealing the through hole of the gasket 5. Under normal conditions, as... Figure 4 As shown, the sealing plate 81 blocks the through hole of the gasket 5, as... Figure 15 As shown, after the pad 5 is pressed, the spring 3 is compressed, and the pad 5 slides towards the cover plate 2, thereby pushing the second slide 6 to slide within the valve body 1. After the second slide 6 slides, it drives the rotating valve core 8 on the second slide 6 to rotate. The sealing plate 81 is a part of the rotating valve core 8, so the sealing plate 81 also rotates. That is, after the rotation, the sealing plate 81 is no longer in the state of blocking the through hole of the pad 5, and the through hole of the pad 5 becomes a passage state, allowing fluid to flow with the fluid in the through hole of the pad 5. This realizes that fluid can flow inside the connector after the pad 5 is pressed. After the second slide 6 slides, there are many ways to drive the rotating valve core 8 to rotate in terms of mechanical principle. For example, the end of the rotating valve core 8 can be set in a gear shape, and the rotating valve core 8 is located in the through hole of the second slide 6. The left and right ends of the rotating valve core 8 protrude from the second slide 6. At the same time, a groove rack that matches the toothed rack at the end of the rotating valve core 8 is set on the inner wall of the valve body 1. The end of the rotating valve core 8 can also rotate after cooperating with the groove rack. In this embodiment, a preferred implementation method is provided, such as... Figure 12 , Figure 13 and Figure 14 As shown, specifically, the rotary valve core 8 also includes a bent portion 82 and a connecting portion 83. The second slide 6 is provided with a notch 62. Since the second slide 6 is cylindrical in shape, as... Figure 10 and Figure 11As shown, the cut 62 is V-shaped, and a transverse mounting hole 63 penetrating the second slide 6 is provided at the cut 62. The bent part 82 is located at the cut 62, as shown. Figure 6 and Figure 9 As shown, the valve body 1 has a groove 11 on its inner wall at the cut 62. The end of the bent part 82 extends into the groove 11, the connecting part 83 passes through the mounting hole 63, and the sealing plate 81 is installed below the connecting part 83. Figure 11 As shown, the through hole of the second slide 6 is convex in shape, as... Figure 8 As shown, the sealing plate 81 is entirely located within the convex shape. Since the end of the bent portion 82 contacts the groove 11, when the second slide 6 is pushed, the groove 11 moves relative to the second slide 6, and the groove 11 can then push the bent portion 82 to rotate. The bent portion 82 is part of the rotary valve core 8; therefore, the entire rotary valve core 8 also rotates, thus controlling the opening or closing of the sealing plate 81 below the rotary valve core 8 relative to the through hole of the pad 5. It is easy to understand that in the static state, the pad 2 slightly protrudes from the valve body 1. At this time, the sealing plate 81 of the rotary valve core 8 and the through hole of the pad 5 are in a closed state of contact, meaning the entire connector is in an open state. When the pads 5 of the two connectors are connected under pressure, the pads 5 slide towards the cover plate 2, and the rotary valve core 8 also rotates towards the cover plate 2. At this time, the through hole of the pad 5 is in a passable state, thus achieving the passage between the two connectors after the pressure connection.

[0044] In a preferred embodiment, the rotary valve core 8 further includes a limiting portion 84, which is located at one end of the connecting portion 83. It is readily understood that the other end of the connecting portion 83 is the bent portion 82. The limiting portion 84 extends out of the second slide block 6. Figure 2 and Figure 5 As shown, a transverse groove 12 is provided on the inner wall of the valve body 1 located at the limiting part 84, and the end of the limiting part 84 is fitted into the transverse groove 12. Since the rotating valve core 8 will move left and right relative to the inner wall of the valve body 1 during the sliding of the second slide block 6, the transverse groove 12 allows the end of the rotating valve core 8 to also move laterally, limiting the vertical displacement of the rotating valve core 8. This makes the sealing plate 81 of the rotating valve core 8 fit more stably with the through hole of the gasket 5, improving the sealing performance in the blocking state. Similarly, as... Figure 14 As shown, the end face of the sealing plate 81 may be provided with a protruding plug 85, which provides better sealing when it extends into the through hole of the pad plate 5.

[0045] In a preferred embodiment, in order to improve the sealing performance of the valve body 1 and prevent fluid leakage, a sealing ring 9 is provided on the fixing rod 7 between the first slide 4 and the second slide 6, that is, the sealing ring 9 is also pre-installed with a corresponding number of holes for the fixing rod 7.

[0046] In summary, the blind-mating fluid connector provided by this invention allows for the internal passage of the connector by simply pressing two identical connectors together. Compared to the prior art which requires both male and female plugs, this reduces manufacturing costs. When the connector is not pressurized, the spring force automatically and quickly separates the two connectors, achieving rapid disconnection and sealing, thus minimizing fluid leakage during the opening and closing process.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
