Description

Technical Field

[0001] This utility model relates to the field of liquid cooling device technology, and in particular to a liquid-cooled blind-plug quick connector. Background Technology

[0002] Blind-mating quick-connect couplings are one of the rapid connection methods for liquid-cooled server water cooling channels and distributor channels in the rack, thereby achieving circulation throughout the water circuit and cooling heat-generating components. The advantage of blind-mating quick-connect couplings is that operators can quickly insert and remove them without precise alignment, greatly improving assembly efficiency and reducing the probability of human error. Most blind-mating quick-connect couplings on the market currently have a radial floating function, allowing for engagement even if the male and female quick-connect coupling axes are not aligned. However, existing blind-mating quick-connect couplings lack a natural return-to-center function, remaining in a misaligned state for extended periods, which can easily cause misalignment at the connection point, thus affecting the subsequent floating effect.

[0003] Therefore, there is an urgent need for a liquid-cooled blind-mating quick connector to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a liquid-cooled blind-plug quick connector to achieve the return function of the connector in its natural state, avoid it being in a misaligned state for a long time, and prevent the connection deviation from affecting the subsequent floating effect of the plug.

[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0006] A liquid-cooled blind-mating quick connector is provided for mating with a first connector of a liquid-cooling device, the liquid-cooled blind-mating quick connector comprising:

[0007] Fixed component, with socket;

[0008] The plug-in assembly includes a second plug and a flat washer. The second plug is used to plug into the first plug. The second plug is inserted into the plug hole and has a gap with the inner wall of the plug hole. The flat washer is arranged around the outer periphery of the second plug and abuts against the first side of the fixing assembly in the axial direction of the second plug.

[0009] Floating components, including a first floating component or a second floating component;

[0010] The first floating component includes a first elastic element, a second elastic element, and a bushing. The bushing, the first elastic element, and the second plug are coaxially sleeved. The first annular portion of the bushing is inserted into the insertion hole, and the second annular portion of the bushing abuts against the second side of the fixing component. The first elastic element is sandwiched between the second annular portion and the limiting protrusion of the second plug, and the second elastic element is sandwiched radially between the fixing component and the first annular portion of the second plug.

[0011] The second floating component includes a third elastic element, one end of which is connected to the fixed component in the axial direction of the second plug, and the other end of which abuts against the limiting protrusion.

[0014] Optionally, at least three second elastic elements are provided, and the at least three second elastic elements are evenly spaced along the circumference of the second connector.

[0015] Optionally, a fixing hole is provided on the inner wall of the insertion hole, one end of the second elastic member is inserted into the fixing hole, and the other end of the second elastic member abuts against the first annular portion.

[0016] Optionally, the fixing component is provided with at least one set of fixing protrusions, the set of fixing protrusions including two fixing protrusions that are radially opposite to each other along the second plug;

[0017] The second elastic element is at least one torsion spring, which is sleeved on the outer periphery of the bushing, and each torsion spring is connected at both ends to a set of two fixed protrusions.

[0018] Optionally, the third elastic element includes a spring assembly, which includes a plurality of springs spaced apart circumferentially along the second connector. The fixing assembly is provided with a plurality of limiting grooves on the side facing the limiting protrusion. One end of one spring is inserted into one of the limiting grooves, and the other ends of the plurality of springs abut against the limiting protrusion.

[0019] Optionally, the third elastic element further includes a gasket, which is disposed at the end of the spring assembly not connected to the fixing component, and the limiting protrusion abuts against the gasket in the axial direction of the second plug.

[0020] Optionally, the second connector includes a quick connector, a pagoda head, and a nut. One end of the quick connector is inserted into the pagoda head, and the other end of the quick connector is used to insert into the first connector. The nut is sleeved on the outer periphery of the pagoda head to form the limiting protrusion.

[0021] The second connector has a shaft clip on its outer periphery, and the flat washer is sleeved on the outer periphery of the second connector. The first elastic member presses against the bushing so that the flat washer is sandwiched between the fixing component and the shaft clip.

[0022] Optionally, the liquid-cooled blind-plug quick connector further includes an auxiliary component, which includes a sleeve and an auxiliary bracket. The sleeve passes through the fixing component, the second elastic element passes through the sleeve, one end of the auxiliary bracket is slidably inserted into the sleeve and abuts against the second elastic element, and the other end of the auxiliary bracket abuts against the first annular portion.

[0023] The beneficial effects of this utility model are as follows:

[0024] The liquid-cooled blind-plug quick connector proposed in this utility model is used for mating with a first connector of a liquid-cooling device. The liquid-cooled blind-plug quick connector includes a fixed assembly, a plug-in assembly, and a floating assembly. The fixed assembly has a socket. The plug-in assembly includes a second plug-in and a flat washer. The second plug-in is used for mating with the first plug-in, and the second plug-in is inserted into the socket with a gap between it and the inner wall of the socket. The flat washer is arranged around the outer periphery of the second plug-in and abuts against the first side of the fixed assembly in the axial direction of the second plug-in.

[0025] The floating component includes a first floating component or a second floating component.

[0026] The first floating component includes a first elastic element, a second elastic element, and a bushing. The bushing, the first elastic element, and the second connector are coaxially sleeved. The first annular portion of the bushing is inserted into the insertion hole, and the second annular portion of the bushing abuts against the second side of the fixed component. The first elastic element is sandwiched between the second annular portion and the limiting protrusion of the second connector, and the second elastic element is radially sandwiched between the fixed component and the first annular portion of the second connector. Specifically, when the second connector is inserted into the first connector, the second connector is subjected to an external force, which compresses the first elastic element, causing the relative position of the second connector and the fixed component to change, thereby realizing the floating of the second connector in its own axial direction. The bushing is fitted around the outer periphery of the second connector. The relative position of the bushing and the second connector in the radial direction of the second connector remains unchanged. The bushing is fitted inside the socket and has a gap with the inner wall of the socket, so that the second connector can float relative to the fixed component in its own radial direction and compress the second elastic element in the moving direction. However, after the second connector and the first connector are inserted into each other, the elastic force of the second elastic element can drive the second connector back to the center position of the socket to ensure that the second connector returns to its correct position.

[0027] The second floating component includes a third elastic element. One end of the third elastic element is fixed to the fixed component along the axial direction of the second connector, while the other end abuts against a limiting protrusion. Specifically, when the second connector is inserted into the first connector, the second connector is subjected to an external force, causing the third elastic element to compress. This changes the relative position of the second connector and the fixed component, thus enabling the second connector to float along its own axial direction. Furthermore, the second connector has a gap with the inner wall of the insertion hole, and the second connector is supported by the elastic force of the third elastic element. The third elastic element can compress or bend, allowing the second connector to float radially or offset around its own axial direction. After the second connector is inserted into the first connector, the elastic force of the third elastic element can also drive the second connector back to the center position of the insertion hole, ensuring the second connector returns to its correct position.

[0043] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] Example 1

[0045] like Figures 1 to 3 As shown, this embodiment provides a liquid-cooled blind-plug quick connector for mating with a first connector of a liquid-cooling device. The liquid-cooled blind-plug quick connector includes a fixing component 8, a plugging component, and a floating component. The fixing component 8 has a socket, and the plugging component includes a second plug 1 and a flat washer 2. The second plug 1 is used to mat with the first plug, and the second plug 1 is inserted into the socket with a gap between it and the inner wall of the socket. The flat washer 2 is circumferentially disposed around the outer periphery of the second plug 1 and abuts against a first side of the fixing component 8 in the axial direction of the second plug 1. In this embodiment, one of the first plug and the second plug 1 is a quick-connect male and the other is a quick-connect female, and the two are plugged together. For example, the second plug 1 can be set as a quick-connect male, while the liquid-cooling device to be connected is set as a quick-connect female.

[0046] The floating assembly includes a first floating assembly, which includes a first elastic element 5, a second elastic element 6, and a bushing 4. The bushing 4, the first elastic element 5, and the second plug-in 1 are coaxially sleeved. The first annular portion 41 of the bushing 4 is inserted into the insertion hole, and the second annular portion 42 of the bushing 4 abuts against the second side of the fixing assembly 8. The first elastic element 5 is sandwiched between the second annular portion 42 and the limiting protrusion 111 of the second plug-in 1. The second elastic element 6 is radially sandwiched between the fixing assembly 8 and the first annular portion 41 of the second plug-in 1.

[0047] Specifically, the fixing component 8 has a first side and a second side opposite to each other in the axial direction of the second connector 1. The first elastic member 5 is sleeved on the outer periphery of the second connector 1 and abuts against the second side of the fixing component 8 through the second annular portion 42 of the bushing 4. Since the first elastic member 5 is sandwiched between the second annular portion 42 and the limiting protrusion 111 in the axial direction of the second connector 1, the first elastic member 5 has elasticity. When the limiting protrusion 111 presses against the first elastic member 5, the first elastic member 5 gives the limiting protrusion 111 a tendency to move away from the second side of the fixing component 8, thereby driving the flat pad 2 sleeved on the second connector 1 to move towards the first side of the fixing component 8 until the flat pad 2 abuts against the first side of the fixing component 8, thereby limiting the relative position of the second connector 1 and the fixing component 8 to remain unchanged. When the second connector 1 is inserted into the first connector, the second connector 1 is subjected to an external force, which compresses the first elastic member 5. This causes the relative position of the second connector 1 and the fixed component 8 to change, thereby enabling the second connector 1 to float in its own axial direction.

[0048] Specifically, the bushing 4 is fitted around the outer periphery of the second connector 1. The relative radial positions of the bushing 4 and the second connector 1 remain unchanged. The bushing 4 is fitted inside the insertion hole and has a gap with the inner wall of the insertion hole. The first annular portion 41 of the bushing 4 is located inside the insertion hole, and the second annular portion 42 is located outside the insertion hole and abuts against the second side of the fixing component 8. This allows the bushing 4 to move only radially relative to the fixing component 8 of the second connector 1. When the second connector 1 floats radially, the second elastic member 6 on the side of the second connector 1 that is closer to it is compressed. After the second connector 1 is inserted into the first connector, the elastic force of the second elastic member 6 drives the second connector 1 back to the center position of the insertion hole to ensure that the second connector 1 returns to its correct position.

[0049] This liquid-cooled blind-mating quick connector not only allows the second connector 1 to float in its own axial and radial directions, but also ensures that the second connector 1 returns to its original position after mating, thereby ensuring the long-term mating effect of the liquid-cooled blind-mating quick connector.

[0050] like Figure 1 As shown, in this embodiment, a shaft clip 3 is provided on the outer periphery of the second connector 1, and a flat washer 2 is sleeved on the outer periphery of the second connector 1. When the first elastic member 5 pushes the second annular portion 42 of the bushing 4 against the second side of the fixing component 8, the flat washer 2 will be clamped between the first side of the fixing component 8 and the shaft clip 3 in the axial direction of the second connector 1. In specific implementation, the flat washer 2 is first sleeved on, and the flat washer 2 can slide on the second connector 1. Then, the shaft clip 3 is provided in the axial direction of the second connector 1, and the shaft clip 3 is used to limit the position of the flat washer 2 on the second connector 1.

[0051] Optionally, a first anti-friction pad 84 is provided on one side of the fixing component 8 that abuts against the flat pad 2 to prevent the flat pad 2 from being worn when it slides radially relative to the fixing component 8 of the second connector 1.

[0052] like Figure 1 As shown, in this embodiment, the second connector 1 includes a pagoda head 11 and a quick connector 12, which are detachably connected. The outer periphery of the pagoda head 11 is provided with a protrusion to form the aforementioned limiting protrusion 111, and the first elastic member 5 is sleeved on the pagoda head 11. In specific implementation, the bushing 4 is first inserted into the insertion hole and the first elastic member 5 is placed on the second annular portion 42 of the bushing 4. Finally, the pagoda head 11 is inserted so that the limiting protrusion 111 presses against the first elastic member 5. Then, one end of the quick connector 12 is inserted into the pagoda head 11, and the other end of the quick connector 12 is used to insert into the first connector.

[0053] like Figure 2 As shown, in this embodiment, the outer periphery of the bushing 4 is stepped, and a stepped structure is formed at the connection between the first annular portion 41 and the second annular portion 42. The first stepped surface of the stepped structure is used to support the first elastic member 5, and the second stepped surface on the other side of the stepped structure is used to press against the fixing component 8.

[0054] Optionally, such as Figure 2 As shown, the second step surface of the stepped structure is provided with a second anti-friction pad 44 to avoid wear caused by the bushing 4 when the second plug 1 slides radially relative to the fixed component 8.

[0055] Optionally, such as Figure 2 As shown, a fixing hole 81 is provided on the inner wall of the insertion hole. One end of the second elastic member 6 is inserted into the fixing hole 81, and the other end of the second elastic member 6 abuts against the bushing 4. In this embodiment, the fixing component 8 includes a fixing block and a fastener 82. The fixing block has an annular structure, and the fixing hole 81 passes through both ends of the second insertion member 1 radially. In specific assembly, the second elastic member 6 can be inserted into the fixing hole 81 first, and then the fastener 82 can be detachably connected to the fixing hole 81 to seal the end of the fixing hole 81 away from the second insertion member 1.

[0056] Optionally, at least three second elastic elements 6 are provided, and the at least three second elastic elements 6 are evenly spaced along the circumference of the second connector 1. Figure 3 As shown, in this embodiment, four second elastic elements 6 are provided in the radial direction of the second connector 1, with adjacent second elastic elements 6 arranged at a 90° angle. The second elastic elements 6 are evenly distributed to ensure the straightening effect of the second connector 1.

[0057] Example 2

[0058] This embodiment provides a liquid-cooled blind-mating quick connector, which differs from the liquid-cooled blind-mating quick connector in Embodiment 1 in that:

[0059] like Figure 4 As shown, the second elastic element 6 is a torsion spring, which is sleeved on the outer periphery of the bushing 4, and both ends of the torsion spring are connected to the fixing component 8. The fixing component 8 is provided with at least one set of fixing protrusions 83, which includes two fixing protrusions 83 arranged radially opposite each other along the second connector 1. Each end of the torsion spring is connected to one of the two fixing protrusions 83 in the set. When the second connector 1 rotates about its own axis or moves radially, the torsion spring will deform. After the second connector 1 is inserted, the torsion spring can drive the second connector 1 back to its original position when it returns to its initial state.

[0060] Optionally, if at least one second elastic element 6 is provided, then at least one set of fixing protrusions 83 is provided on the fixing component 8, and each set of fixing protrusions 83 includes two fixing protrusions 83 arranged radially opposite to each other along the second connector 1. The rotation centers of the plurality of second elastic elements 6 are all sleeved on the second connector 1, and the two ends of one second elastic element 6 are respectively connected to the two fixing protrusions 83 of a set of fixing protrusions 83, and the plurality of sets of fixing protrusions 83 are arranged circumferentially spaced along the second connector 1.

[0061] In addition, the liquid-cooled blind-plug quick connector provided in this embodiment is the same as the liquid-cooled blind-plug quick connector in Embodiment 1, and will not be described again here.

[0062] Example 3

[0063] This embodiment provides a liquid-cooled blind-mate quick connector, which differs from the liquid-cooled blind-mate quick connector in Embodiment 1 in that:

[0064] like Figure 5 As shown, the first elastic element 5 includes a main spring 51 and an auxiliary spring 52. The main spring 51 and the auxiliary spring 52 are coaxially sleeved on the outer periphery of the second connector 1. The main spring 51 is sleeved on the outside of the auxiliary spring 52. This shortens the axial length of the first elastic element 5 in the second connector 1 without changing or reducing the elastic force of the first elastic element 5, so as to meet the insertion requirements when the axial space of the second connector 1 is limited. In addition, in order to avoid interference between the main spring 51 and the auxiliary spring 52 when the first elastic element 5 is circumferentially compressed in the second connector 1, a first separating protrusion 43 is provided on the side of the second annular portion 42 facing the limiting protrusion 111. The auxiliary spring 52 is located on the side of the first separating protrusion 43 closer to the second connector 1, and the main spring 51 is located on the side of the first separating protrusion 43 away from the second connector 1.

[0065] Optionally, a second dividing protrusion 112 is provided on the side of the limiting protrusion 111 facing the bushing 4. The second dividing protrusion 112 is axially opposite to the first dividing protrusion 43 in the second connector 1. The main spring 51 and the auxiliary spring 52 are located on both sides of the second dividing protrusion 112.

[0066] In addition, the liquid-cooled blind-plug quick connector provided in this embodiment is the same as the liquid-cooled blind-plug quick connector in Embodiment 1, and will not be described again here.

[0067] Example 4

[0068] This embodiment provides a liquid-cooled blind-mate quick connector, which differs from the liquid-cooled blind-mate quick connector in Embodiment 1 in that:

[0069] like Figure 6 and Figure 7 As shown, the floating assembly includes a second floating assembly, which includes a third elastic element 7. One end of the third elastic element 7 is connected to the fixed assembly 8 along the axial direction of the second connector 1, and the other end abuts against the limiting protrusion 111 of the second connector 1. When the second connector 1 is inserted into the first connector, the second connector 1 is subjected to an external force, causing the third elastic element 7 to compress. This changes the relative position of the second connector 1 and the fixed assembly 8, thereby enabling the second connector 1 to float along its own axial direction. Furthermore, the second connector 1 has a gap with the inner wall of the insertion hole, and the second connector 1 is supported by the elastic force of the third elastic element 7. The third elastic element 7 can be compressed or bent, allowing the second connector 1 to float radially or deflect around its own axial direction. After the second connector 1 is inserted into the first connector, the elastic force of the third elastic element 7 can also drive the second connector 1 back to the center position of the insertion hole, ensuring that the second connector 1 returns to its correct position.

[0070] like Figure 7 As shown, in this embodiment, the second connector 1 includes a quick connector 12, a pagoda head 11, and a nut 13. One end of the quick connector 12 is inserted into the pagoda head 11, and the other end of the quick connector 12 is used to be inserted into the first connector. The nut 13 is threaded onto the outer periphery of the pagoda head 11 to form a limiting protrusion 111 of the second connector 1.

[0071] Optionally, the third elastic element 7 is a spring assembly 71, which includes multiple springs spaced circumferentially around the second connector 1. Multiple limiting grooves 85 are provided on the fixing assembly 8 facing the limiting protrusion 111. One end of each spring is inserted into a corresponding limiting groove 85, while the other ends of the multiple springs abut against the limiting protrusion 111. The limiting grooves 85 are used to restrict the axial relative position of one end of the spring assembly 71 and the fixing assembly 8 with the second connector 1. Because the third elastic element 7 is always pressed against the limiting protrusion 111, it can be ensured that one end of the third elastic element 7 is always inserted into the limiting groove 85 and does not detach. A limiting post is provided at the bottom of the limiting groove 85, and the spring is inserted into the limiting groove 85 and passes through the outer periphery of the limiting post.

[0072] In this embodiment, the fixing component 8 is also provided with an annular groove, and multiple limiting grooves 85 are spaced apart at the bottom of the annular groove. Thus, one end of the multiple springs inserted into the limiting grooves 85 is also located in the annular groove. The spring group 71 is spaced apart from the inner wall of the annular groove to ensure that the spring group 71 does not interfere with the inner wall of the annular groove when the second connector 1 is radially offset.

[0073] Optionally, such as Figure 7 As shown, the third elastic member 7 also includes a gasket 72, which is disposed at the end of the spring assembly 71 that is not connected to the fixing component 8. The limiting protrusion 111 of the second plug 1 presses against the gasket 72 in the axial direction of the second plug 1 to ensure that the other end of the spring assembly 71 is pressed by the limiting protrusion 111 and the force is uniform at all points.

[0074] In addition, the liquid-cooled blind-plug quick connector provided in this embodiment is the same as the liquid-cooled blind-plug quick connector in Embodiment 1, and will not be described again here.

[0075] Example 5

[0076] This embodiment provides a liquid-cooled blind-mate quick connector, which differs from the liquid-cooled blind-mate quick connector in Embodiment 1 in that:

[0077] like Figure 8 and Figure 9As shown, the liquid-cooled blind-plug quick connector also includes an auxiliary component 9, which includes a sleeve 91 and an auxiliary bracket 92. The sleeve 91 is inserted into the fixing component 8, and the second elastic member 6 is inserted into the sleeve 91. One end of the auxiliary bracket 92 is slidably inserted into the sleeve 91 and abuts against the second elastic member 6, while the other end of the auxiliary bracket 92 abuts against the first annular portion 41. In this embodiment, the auxiliary bracket 92 includes a straight rod and an arc-shaped rod disposed at the end of the straight rod away from the sleeve. The shape of the arc-shaped rod is adapted to the first annular portion 41 of the bushing 4. That is, the second elastic member 6 is used to push the auxiliary bracket 92 to move, and the auxiliary bracket 92 then pushes the bushing 4 and the second plug-in component 1 to float. Among them, adding the auxiliary bracket 92, compared with directly using the second elastic member 6 to push the bushing 4, can further prevent the bushing 4 from sliding relative to the second elastic member 6. The arc-shaped rod is partially surrounded by the bushing 4, and its abutment area is much larger than that of direct abutment by the second elastic member 6. Adding a sleeve 91 can protect the second elastic element 6 during the radial compression process of the second connector 1, thereby preventing part of the second elastic element 6 from being trapped between the first annular portion 41 and the fixing component 8.

[0078] In this embodiment, a protrusion is provided at one end of the straight rod that passes through the sleeve 91. The protrusion is used to limit the farthest distance that the second elastic member 6 pushes the push rod auxiliary bracket 92, that is, to prevent the second elastic member 6 from pressing the push rod auxiliary bracket 92 out of the sleeve 91. In this embodiment, the sleeve 91 includes a cylinder body and a cylinder cover. Both ends of the cylinder body are open. The second elastic member 6 is installed in the cylinder body, and the cylinder cover is used to close the end of the cylinder body away from the auxiliary bracket 92.
