The cover is fixedly connected to one end of the operating handle. The bottom of the cover is open and has a cavity for accommodating the plug. The locking component is disposed on the inner wall of the cover so that when the cover is fitted over the plug, the cover and the plug are axially linked and relatively fixed in the circumferential direction.

Description

Technical Field

[0001] This invention relates to the field of liquid cooling technology for electronic devices, and more particularly to a device for assembling and disassembling fluid connectors in confined spaces. Background Technology

[0002] Liquid cooling is a crucial method for heat dissipation in electronic equipment. Coolant circulates repeatedly in loops between different modules, carrying away heat and ensuring normal operation. These liquid loops are connected via various connectors. Fluid connectors, as self-sealing, quick-pluggable liquid connectors, are widely used in the interconnection of various liquid cooling modules. When supplying liquid to a single, relatively independent device, a manual fluid connector is typically chosen as the interface between the piping and the electronic equipment, enabling quick installation and removal. A manual fluid connector consists of a socket and a plug. When used in pairs, the socket is installed on the electronic equipment, serving as the inlet / outlet for the cold plate flow channel; the plug is installed on the liquid cooling hose. This connection method allows for quick connection and disconnection of the liquid cooling loop. Furthermore, because the plug is installed on the liquid cooling hose, the installation precision requirements for the electronic equipment are lower, making it convenient to use.

[0003] Existing manual self-sealing fluid connectors typically have guide grooves on the plug and positioning pins on the socket (e.g., Figure 5 and Figure 7 (As shown). During the mating process, the operator holds the plug and places it on the socket. By pressing and rotating the plug, the positioning pin slides along the guide groove to the end, thus locking and disconnecting the connector. However, in actual use, it has been found that compared to the connector size (generally 30mm in diameter), the operator's hand is relatively large, and the operating space required to handle the plug is usually around 100mm. With the continuous improvement of the integration of electronic devices, the environmental space in which electronic devices are located is constantly shrinking, and the space available for operation is also decreasing. In some situations, there is no space to directly operate the plug by hand. In addition, in some cases, electronic devices are installed inside the whole machine, and the operator cannot directly access and disassemble the connector, which brings difficulties to the subsequent maintenance and debugging of the equipment. At the same time, the connector needs to be pressed and rotated forcefully when mating, but the flexible tube connected to the plug cannot transmit the torque and pressure required for operation over long distances, so it is impossible to drive the connector to complete the mating action through the tube. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention proposes a disassembly and assembly device for fluid connectors in confined spaces.

[0005] This invention proposes a device for assembling and disassembling fluid connectors in confined spaces. The fluid connector includes a plug and a socket. The fluid connector has a guide structure that allows the plug and socket to rotate relative to each other during axial movement. The device includes an operating handle, a cover, and a locking component. The cover is fixedly connected to one end of the operating handle. The bottom of the cover is open and has a cavity for accommodating the plug. The locking component is disposed on the inner wall of the cover so that when the cover is fitted over the plug, the cover and the plug are linked axially and relatively fixed circumferentially. By axially moving the operating handle, the cover moves synchronously axially, causing the plug to rotate relative to the socket under the action of the guide structure, thereby locking or disconnecting the fluid connector.

[0006] Preferably, the guide structure includes an upper limit hole in the plug, and a locking member having a block that is adapted to the limit hole. The locking member enables the cover and the plug to be linked in the axial direction and relatively fixed in the circumferential direction. Specifically, when the cover is coaxially sleeved on the outside of the plug and moves axially to a first position where the block and the limit hole are aligned in the circumferential direction, part of the block is inserted into the limit hole to connect the cover and the plug together.

[0007] Preferably, the guide structure includes a guide groove on the plug and a positioning pin fixed on the outer wall of the socket. The socket has a first elastic element arranged coaxially with the socket. When the cover moves to the first position, the plug pushes the first plate to compress the first elastic element axially downward. The block is provided with a groove and an inclined first wall. The bottom wall of the groove is connected to the first wall. When the compressed first elastic element pushes the plug to move axially upward, the positioning pin slides along the first wall to push the block out of the limiting hole.

[0008] Preferably, the first elastic element has a first spring arranged coaxially with the socket and an annular first plate. The two ends of the first spring are fixedly connected to the inner wall of the socket and the first plate, respectively. When the cover moves to the first position, the plug pushes the first plate to compress the first spring axially downward.

[0009] Preferably, the plug has a first cavity for accommodating the socket and a hollow cylindrical body. The cylindrical body is coaxially arranged in the first cavity. The socket has a second cavity. A first spring and a first plate are disposed in the second cavity. The cylindrical body has a first through hole that communicates with the inner cavity of the cylindrical body. A second through hole is provided on the first plate. Specifically, the plug pushes the first plate to move axially downward as follows: when the plug moves axially downward, the cylindrical body contacts the first plate and pushes the first plate to move axially; when the cylindrical body contacts the first plate, the second through hole communicates with the first through hole.

[0010] Preferably, the engaging member further comprises a second elastic element fixedly connected between the block and the inner wall of the cover. The distance between the two blocks is less than the outer diameter of the plug so that when the cover is fitted over the plug, the second elastic element is pressed away from the plug. When the block moves to the first position in the cover, the pressed second elastic element pushes the block to move until part of the block is inserted into the limiting hole.

[0011] Preferably, the guide groove is connected to the limiting hole, and an inclined second wall is provided at the opening of the groove. When a part of the block is inserted into the limiting hole, the second wall is flush with the groove wall of the guide groove to form a continuous guide surface for the positioning pin to slide. When a part of the block is inserted into the limiting hole, the axially moving plug forces the positioning pin to move along the continuous guide surface into the groove.

[0012] Preferably, the guide groove is spiral-shaped, and the positioning pin is adapted to the guide groove. The process of causing the plug to rotate relative to the socket under the action of the guide structure is as follows: when a part of the block is inserted into the limiting hole, the axially moving plug forces the positioning pin to move along the continuous guide surface to simultaneously drive the plug to rotate relative to the socket.

[0013] Preferably, the second elastic element has a first rod, a second rod, and a second spring arranged coaxially. The first rod is fixed to the inner wall of the cover, and the second rod is fixed to the block. The first rod has a third cavity to accommodate the second rod. One end of the second rod is inserted into the third cavity, and the second spring is sleeved on the outside of the first and second rods. When the cover moves toward the first position, the block pushes the second rod to move along the axis of the third cavity and compresses the second spring. When the cover moves to the first position, the compressed second spring pushes the block to move until part of the block is inserted into the limiting hole.

[0014] Preferably, the cover is composed of a second plate and a third plate, and the second plate and the third plate form a cavity for accommodating the plug. The plug is connected to a flexible tube, and the flexible tube communicates with the plug. The flexible tube has an end and a body. The end is fixed to and communicates with the plug, and the body communicates with the end. A third through hole is provided on the second plate. The diameter of the third through hole is smaller than the outer diameter of the end and larger than the outer diameter of the body.

[0015] In this invention, by setting an operating handle and a cover, the operating point is shifted from the connector itself to an area away from confined spaces. Operators no longer need to extend their hands into narrow spaces less than 100mm wide; they can simply push or pull the long handle from outside the space to transmit pressure to the plug through the cover, completing the mating action. This overcomes the limitations of traditional manual connectors on operating space, significantly reducing the installation requirements around electronic devices and adapting to the confined environments of highly integrated electronic devices. By setting a block on the inner wall of the cover that mates with the plug's limiting hole, the block automatically engages using a first elastic element, and automatically pops out using a beveled surface on the block in conjunction with a second elastic element inside the socket. The entire locking and unlocking operation of the cover and plug requires no additional manual operation; operators only need to push the cover and stop pressing it, which not only reduces operational difficulty and simplifies the process but also further improves disassembly efficiency.

Detailed Implementation

[0017] Reference Figure 1 and Figure 2 This invention proposes a device for assembling and disassembling fluid connectors in confined spaces, primarily applicable to applications such as... Figure 5 and Figure 7The fluid connector shown includes a plug 3 and a socket 4. The socket 4, in a separated state, is mounted on the cold plate of the electronic device, while the plug 3 is mounted on a hose 5.

[0018] The specific structure of socket 4 is as follows Figure 5 , Figure 7 and Figure 8 The socket 4 has a first elastic element 41 and a second cavity 42 arranged coaxially with the socket 4, and a second push rod 43 arranged coaxially with the first plate 412; the first elastic element 41 has a first spring 411 arranged coaxially with the socket 4 and an annular first plate 412, and the two ends of the first spring 411 are fixedly connected to the inner wall of the socket 4 and the first plate 412 respectively.

[0019] The specific structure of plug 3 is as follows Figure 5 , Figure 7 and Figure 8 The plug 3 has a first cavity 33 for accommodating the socket 4, a hollow cylindrical body 34, and a first push rod 35 coaxially arranged with the cylindrical body 34. A third spring 36 is sleeved on the first push rod 35, and the two ends of the third spring 36 are fixed to the inner wall of the cylindrical body 34 and the rod end of the first push rod 35, respectively. The flexible hose 5 communicates with the inner cavity of the cylindrical body 34. The cylindrical body 34 is coaxially arranged in the first cavity 33. The first spring 411 and the first plate 412 are arranged in the second cavity 42. The cylindrical body 34 has a first through hole 341 that communicates with the inner cavity of the cylindrical body 34. A second through hole 4121 is provided on the first plate 412. The outer diameter of the rod end of the second push rod 43 is the same as the outer diameter of the rod end of the first push rod 35, the inner diameter of the first through hole 341, and the inner diameter of the second through hole 4121. When plug 3 and socket 4 are connected, plug 3 moves downward along the axial direction, causing cylinder 34 to contact the first plate 412 and push the first plate 412 to move axially. At this time, the first through hole 341 on cylinder 34 is connected to the second through hole 4121 on the first plate 412, and the second push rod 43 extends into the interior of cylinder 34 through the connected first through hole 341 and second through hole 4121 and contacts the first push rod 35, pushing the first push rod 35 into the hose 5. At this time, hose 5 is connected to cylinder 34 and the second cavity 42 of socket 4, forming a liquid cooling circuit for fluid to pass through.

[0020] In order to lock the plug 3 and socket 4 in place after mating, the fluid connector also has a guide structure that causes the plug 3 to rotate relative to the socket 4 during axial movement. This guide structure is specifically as follows: Figure 5As shown: The guide structure includes an upper limit hole 31 on the plug 3, a guide groove 32 on the plug 3, and a positioning pin 44 fixed on the outer wall of the socket 4. The guide groove 32 is spiral-shaped, and the positioning pin 44 is adapted to the guide groove 32. This arrangement can convert the downward axial pressing force of the plug 3 into a torque that drives the plug 3 to rotate relative to the socket 4 in a predetermined direction during docking. At the same time, it also allows the positioning pin 44 on the socket 4 to slide along the guide groove 32, guiding the socket 4 and the plug 3 to engage with the second spring 223 inside the connector. The positioning pin 44 finally slides into the elliptical limit hole 31 at the end of the guide groove 32. With the rebound force of the second spring 223 and the third spring 36 inside the fluid connector, the socket 4 and the plug 3 are locked together, ensuring the continuity of the liquid cooling circuit formed inside.

[0021] The aforementioned fluid connector is suitable for applications with a certain amount of operating space. However, when the operating space is limited and the operator's hands cannot directly access the plug 3 and socket 4, the fluid connector cannot be used to mate the plug 3 and socket 4 without tools. Therefore, a special design is provided to address the rotary mating characteristic of this fluid connector. Figure 2 The disassembly and assembly equipment includes an operating handle 1, a cover 2, and a locking component. The cover 2 is fixedly connected to one end of the operating handle 1, and the bottom of the cover 2 is open with a cavity for accommodating the plug 3. Figure 6 The cover 2 consists of a second plate 24 and a third plate 23, which together form a cavity for accommodating a plug 3. A flexible tube 5 is inherently connected to the plug 3 and communicates with it. The flexible tube 5 has an end 51 and a body 52. ​​The end 51 is fixed to and communicates with the plug 3, and the body 52 communicates with the end 51. A third through hole 25 is provided on the second plate 24. The diameter of the third through hole 25 is smaller than the outer diameter of the end 51 but larger than the outer diameter of the body 52. ​​By restricting the movement of the plug 3 through the third through hole 25 on the second plate 24, the second plate 24 of the cover 2 can be locked outside the end 51 of the flexible tube 5, thereby achieving the purpose of controlling the movement of the plug 3 through the cover 2.

[0022] In use, by extending the operating handle 1 of a certain length into the position of the plug 3, and then moving the operating handle 1 axially to drive the cover 2 to move axially synchronously, the plug 3 can rotate relative to the socket 4 under the action of the guide structure, thereby locking or disconnecting the fluid connector. This setting can force the positioning pin 44 to move along the spiral guide groove 32 when the plug 3 moves axially relative to the socket 4. Figure 9 As shown in the image.

[0023] The above design solves the problem in traditional solutions where the plug 3 is mounted on the flexible hose 5. The flexible hose 5 is highly flexible, making it difficult to transmit the torque and pressure required for pressing and rotating over long distances, thus preventing the connector from engaging via the tubing. This invention completely isolates the influence of the flexible hose 5 by locking the plug 3 with a rigid cover 2 and applying axial force directly through a long operating handle 1. Axial movement is automatically converted into the rotational motion required by the socket 4 via the guide groove 32 on the plug 3, eliminating the need to apply torque through the hose 5. This achieves stable and reliable torque transmission, ensuring smooth locking and disconnection of the connector during long-distance operation.

[0024] To ensure that plug 3 does not move synchronously with socket 4, such as Figure 2 As shown, the engaging component is installed on the inner wall of the cover 2, allowing the cover 2 and the plug 3 to move axially and be relatively fixed circumferentially when the cover 2 is fitted over the plug 3. Specifically, as... Figure 3 and Figure 4 The engaging component has a block 21 and a second elastic member 22 fixedly connected between the block 21 and the inner wall of the cover 2. The block 21 is adapted to the limiting hole 31, and the distance between the two blocks 21 is less than the outer diameter of the plug 3 so that when the cover 2 is fitted over the plug 3, the second elastic member 22 is squeezed away from the plug 3. This arrangement allows the second elastic member 22 to be compressed by the outer wall of the plug 3 when the block 21 is fitted over the plug 3 along with the cover 2. This compressed state is maintained until the block 21 moves to the first position. When the block 21 moves to the first position (that is, the position where the block 21 and the limiting hole 31 are aligned in the circumferential direction), the compressed second elastic member 22 will push the block 21 toward the plug 3 until a part of the block 21 is inserted into the limiting hole 31 to lock the cover 2 and the plug 3 together. In this way, while the operator pushes the plug 3 down using the cover 2, the torque can also be transmitted through the rigid connection between the operating handle 1, the cover 2, the block 21 and the plug 3, making it convenient for the operator to control the plug 3 to rotate synchronously with the cover 2 in the circumferential direction by operating the cover 2.

[0025] In this embodiment, the structure of the second elastic element 22 is as follows: Figure 4As shown: The second elastic element 22 has a first rod 221, a second rod 222, and a second spring 223 arranged coaxially. The first rod 221 is fixed to the inner wall of the cover 2, and the second rod 222 is fixed to the block 21. The first rod 221 has a third cavity 2211 to accommodate the second rod 222. One end of the second rod 222 is inserted into the third cavity 2211, and the second spring 223 is sleeved on the outside of the first rod 221 and the second rod 222. When the cover 2 moves toward the first position, the block 21 pushes the second rod 222 to move along the axis of the third cavity 2211 and compresses the second spring 223. When the cover 2 moves to the first position, the compressed second spring 223 pushes the block 21 toward the plug 3 until the pushing part of the block 21 is inserted into the limiting hole 31.

[0026] After the plug 3 and the housing 2 are locked together by the block 21, the operator continues to move the operating handle 1 along the axial direction of the plug 3. The socket 4, installed on the electronic device, cannot rotate. At this time, the operator can rotate the housing 2 while moving the plug 3 axially, causing the plug 3 to rotate relative to the socket 4 under the action of the guide structure. During this process, the positioning pin 44 on the socket 4 will move along the guide groove 32. Since the guide groove 32 is connected to the limiting hole 31, the block 21 will eventually move into the limiting hole 31. Because part of the block 21 is currently embedded in the limiting hole 31, to ensure that the presence of the block 21 does not affect the normal movement of the positioning pin 44, such as... Figure 3 A groove 211 for accommodating the positioning pin 44 is also provided on the block 21. An inclined second wall 213 is provided at the opening of the groove 211. When part of the block 21 is inserted into the limiting hole 31, the second wall 213 is flush with the groove wall of the guide groove 32 to form a continuous guide surface for the positioning pin 44 to slide. Therefore, when the operator moves the plug 3 axially, the positioning pin 44 on the socket 4 will move along the guide surface until it enters the groove 211 on the block 21. Figure 9 (a).

[0027] Next, simply remove block 21 from the limiting hole 31, and plug 3 and socket 4 will be connected together under the locking of positioning pin 44 and limiting hole 31. Based on this, as Figure 3An inclined first wall 212 is also provided on the block 21, and the bottom wall of the groove 211 is connected to the first wall 212. As the plug 3 moves axially, the cylinder 34 inside the plug 3 will press the first elastic element 41 inside the socket 4 in the direction of movement. That is, the cylinder 34 will contact the first plate 412 and press the first spring 411 connected to the first plate 412 in the direction of movement. When the operator controls the movement of the plug 3, he will apply a force to the plug 3 through the operating handle 1 and the cover 2. This force also helps to keep the first spring 411 in a compressed state. After the positioning pin 44 moves into the groove 211 on the block 21, the operator can release the force applied to the plug 3. At this time, the compressed first spring 411 will push the cylinder 34 and the plug 3 in the opposite direction of movement under the action of its own elasticity. At the same time, the cover 2 outside the plug 3 will also move synchronously with the plug 3. At this point, if the position of the cover 2 remains unchanged and stationary from the perspective of the relativity of motion, then the socket 4 will move axially away from the cover 2. During this process, the positioning pin 44 will slide along the first wall 212. When the positioning pin 44 moves to the end of the first wall 212, the block 21 can be removed from the limiting hole 31. Figure 9 As shown in (c), the locking relationship between the cover 2 and the plug 3 can be released.

[0028] Finally, the operator only needs to remove the cover 2 from the confined space using the operating handle 1. The invention features a retractable block 21 driven by a second elastic element 22 on the inner wall of the cover 2. When the cover 2 is fitted over the plug 3, the block 21 automatically retracts under pressure from the outer wall of the plug 3; when the cover 2 moves to a predetermined position, the block 21 automatically engages with the limiting hole 31 on the plug 3 under elastic force, thereby achieving dual fixation of the cover 2 and the plug 3 in both the axial and circumferential directions. This design ensures that the cooperation between the block 21 and the limiting hole 31 guarantees that the cover 2 can stably transmit axial pressing force and rotational torque, avoiding connection failure caused by the relative slippage of the cover 2 and the plug 3 during operation. At the same time, the automatic insertion of the block 21 does not require additional manual alignment or locking action. The operator only needs to push the cover 2 to achieve automatic connection, simplifying the operation process. Combined with the elastic reset mechanism set in the socket 4, when the plug 3 retracts under the action of elasticity, the inclined surface on the block 21 cooperates with the positioning pin 44 to automatically push the block 21 out of the limiting hole 31, realizing the rapid separation of the cover 2 and the plug 3, further improving the disassembly efficiency.

[0029] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
