Floating modules, blind-mating connectors and liquid cooling systems

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411188607.7, filed on August 28, 2024, entitled "Floating Module, Blind-Match Connector and Liquid Cooling System", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of mechanism design technology, specifically to a floating module, a blind mating connector, and a liquid cooling system. Background Technology

[0004] A blind-mating connector is a device that enables precise connections in situations with poor visibility or uncertainty. In related technologies, to enhance the ability of blind-mating connectors to absorb mating deviations, one of the connector's socket and pin is typically mounted on a floating module.

[0005] However, the floating module can only move along the mating direction and perpendicular to the mating direction. When either the pin or the plug of the blind mating connector is tilted, the floating module cannot absorb this mating deviation, which can easily cause the plug and pin to fail to be properly inserted. Even if forced to insert, it can easily cause poor contact and damage to the plug or pin. Summary of the Invention

[0006] In view of this, this application provides a floating module, a blind mating connector, and a liquid cooling system to solve the problems in the related art, where the floating module of the blind mating connector cannot be used in working conditions where either the pin or the plug of the blind mating connector is tilted, which easily causes the plug and the pin to fail to mate smoothly, and even if forced to mate, it is easy to cause poor contact and damage to the plug or the pin.

[0007] In a first aspect, this application provides a floating module for a blind mating connector, comprising:

[0008] The main body has a guide channel formed inside it, and a first flange and a second flange are formed on the inner wall of the guide channel at intervals along the axial direction of the guide channel.

[0009] The first connector is at least partially disposed in the guide channel, and an annular protrusion is formed on the outer periphery of the first connector, the annular protrusion being located between the first flange and the second flange.

[0010] The return slider is movably disposed in the guide channel and surrounds the first connector. The return slider abuts against the side of the annular protrusion near the second flange. A guide slope is formed between the return slider and the annular protrusion. Along the direction near the first flange, the guide slope is inclined in a direction away from the axis of the guide channel.

[0011] An elastic element is disposed within the guide channel and supported between the return slider and the second flange.

[0012] Beneficial effects: During use, when the first connector is connected to the corresponding second connector, and when the first connector and the second connector deviate along the axial or radial direction, or when the first connector and the second connector are set at an angle, the first connector of the floating module can contact the guide module. The guide module can apply a force to the first connector, which can be transmitted to the return slider through the annular protrusion, thereby pushing the return slider to move backward. At the same time, the first connector moves along the direction of the force, realizing the floating of the first connector, so as to ensure that the first connector can accurately connect with the corresponding second connector, and the angular deviation of the first connector can be absorbed by the elastic element.

[0013] Furthermore, since the guide ramp is configured to be inclined in a direction away from the axis of the guide channel along the direction close to the first flange, the first connector can move axially relative to the guide channel, move radially relative to the guide channel, and be set at an angle to the axis of the guide channel.

[0014] With this configuration, regardless of whether the pins and plugs of the blind-mating connector deviate along the axial or radial direction of the blind-mating connector, or whether either the plug or pin of the blind-mating connector tilts, the floating module of this application embodiment can absorb the error between the pins and plugs of the blind-mating connector, thereby ensuring that the pins and plugs of the blind-mating connector can be smoothly inserted into place without damaging the blind-mating connector.

[0015] Furthermore, the floating module in this embodiment of the application uses an elastic element to cooperate with the return slider, ensuring that the first plug has a large floating amount in multiple directions. This reduces the number of elastic elements required for the floating module, lowers the cost of the floating module, and makes the structure of the floating module more compact, reducing the space required by the floating module.

[0016] Therefore, the floating module of this application embodiment can overcome the problems in related technologies where the floating module of a blind mating connector cannot be used in situations where either the pin or the plug of the blind mating connector is tilted, which can easily cause the plug and pin to fail to mate smoothly, resulting in poor contact and damage to the plug or pin. Furthermore, it can reduce the number of elastic components required by the floating module, lowering its cost, and the floating module requires less space and has a compact structure. In addition, the above-mentioned floating module has a simple structure, is easy to assemble, and is safe and reliable to use, making it easy to implement and promote its application.

[0017] In some alternative embodiments, a guide ramp is disposed around the outer periphery of the first connector, and the center line of the guide ramp coincides with the axis of the guide channel.

[0018] Beneficial effects: With this configuration, when the first and second connectors are inserted into each other, the return slider can apply a force to the annular protrusion of the first connector through the guide slope. This force can be decomposed into radial and axial components along the guide channel. When the first and second connectors separate, the floating module can separate from the guide module, thereby losing the force applied by the guide module. At this time, the force applied by the return slider to the annular protrusion in the radial direction along the guide channel can drive the first connector to be centered in the guide sleeve.

[0019] In some alternative implementations, the guide ramp includes:

[0020] The first annular surface is disposed on the annular protrusion;

[0021] The second annular surface is set on the return slider, and the slopes of the first and second annular surfaces are the same.

[0022] Beneficial effect: This design ensures smoother movement of the annular protrusion relative to the return slider.

[0023] In some alternative implementations, the first connector includes:

[0024] The plug-in section is located outside the main body and on the side of the annular protrusion away from the elastic element;

[0025] A connecting segment connects the plug-in segment and the annular protrusion. The diameter of the plug-in segment is greater than the inner diameter of the first flange, and the diameter of the connecting segment is less than or equal to the inner diameter of the first flange.

[0026] Beneficial effects: With this configuration, when the first connector has been inserted into the second connector but the liquid-cooled electronic device has not yet been moved to a fixed position, the operator can continue to push the liquid-cooling device along the insertion direction of the first and second connectors. The diameter of the connecting section is less than or equal to the inner diameter of the first flange, which can be inserted into the guide channel and compress the elastic element, thereby ensuring that the electronic device can be installed smoothly without damaging the blind-mating connector.

[0027] In some alternative implementations, the plug segment includes:

[0028] Connector;

[0029] A fixing sleeve is fitted onto the outer periphery of the connector, and the connecting section includes a connecting tube that is connected to the fixing sleeve.

[0030] The first sealing ring is fitted over the connector and sandwiched between the connector and the fixing sleeve.

[0031] Beneficial effects: With this configuration, the blind plug, the fixing sleeve, and the connecting pipe are connected in sequence, which can be used to transfer coolant. The first sealing ring can be used to improve the sealing between the plug and the fixing sleeve and prevent coolant leakage.

[0032] In some alternative embodiments, the elastic element includes a spring surrounding the first connector;

[0033] A first anti-detachment ring groove is formed on the return slider, and the first end of the spring is limited to the first anti-detachment ring groove; and / or,

[0034] A second anti-disengagement ring groove is formed on the second flange, and the second end of the spring is limited to the second anti-disengagement ring groove.

[0035] Beneficial effects: The first and second anti-slip ring grooves can be used to limit the spring, preventing it from slipping and ensuring that the spring can continuously support the return slider. Simultaneously, the first and second anti-slip ring grooves, together with the inner wall of the guide channel, can restrict the spring's extension and contraction perpendicular to the compression direction, preventing the spring from bending.

[0036] In some alternative implementations, the main body includes:

[0037] The base has a first flange disposed on it and a second flange detachably connected to the end of the base away from the first flange.

[0038] Beneficial effect: With this configuration, the base and the second flange can be separated from each other during the assembly process, so that the operator can put the first connector, the return slider and the spring into the guide channel in sequence, and then connect the second flange to the base, thereby limiting the first connector, the return slider and the spring in the guide channel.

[0039] In some alternative implementations, the inner diameter of the first flange is smaller than the outer diameter of the return slider.

[0040] Beneficial effect: This setting can prevent the return slider from slipping out of the guide channel.

[0041] Secondly, this application also provides a blind mating connector, comprising:

[0042] The floating module provided in the first aspect of this application;

[0043] The second connector can be plugged into the first connector.

[0044] Beneficial Effects: The blind mating connector of the second aspect of this application includes or uses the floating module of the first aspect of this application, and therefore has its beneficial effects. Specifically, the blind mating connector of the embodiments of this application can overcome the problems in related technologies where the floating module of the blind mating connector cannot be used in situations where either the pin or the plug of the blind mating connector is tilted, easily causing the plug and pin to fail to mate smoothly, easily causing poor contact, damage to the plug or pin, etc. Furthermore, it can reduce the number of elastic elements required by the floating module, thereby reducing the cost of the blind mating connector. The blind mating connector also requires less space and has a compact structure. In addition, the above-mentioned floating module has a simple structure, is easy to assemble, and is safe and reliable to use, facilitating implementation and widespread application.

[0045] In some alternative implementations, the blind-mating connector further includes:

[0046] The guide sleeve has a second connector located inside it. The guide sleeve has a guide section, and the inner diameter of the guide section gradually decreases along the direction approaching the second connector.

[0047] Beneficial effects: In related technologies, the guide module of a blind mating connector generally includes multiple guide pins set on the outer periphery of the second mating member. The floating module is correspondingly provided with positioning holes that correspond to the guide pins. When the floating module and the guide module are mated, the guide pins can be inserted into the positioning holes, thereby enabling the plug and the pin to accurately mate.

[0048] However, the guide pins need to be set in two or more, which increases the volume of the floating module and exacerbates the space constraints of the electronic device.

[0049] The blind-mating connector of this application embodiment includes a guide sleeve and a second plug member disposed in the guide sleeve. When the first plug member is connected to the corresponding second plug member, when the first plug member and the second plug member deviate along the axial and radial directions, and the first plug member and the second plug member are set at an angle, the first plug member of the floating module can contact the guide section of the guide sleeve. The guide section can apply a force to the first plug member. The force can be transmitted to the return slider through the annular protrusion, thereby pushing the return slider to move backward. At the same time, the first plug member moves along the direction of the force, thereby realizing the floating of the first plug member, so that the first plug member can accurately mate with the second plug member.

[0050] Moreover, compared to the scheme that uses guide pins and guide holes, the structure is simpler and more compact, and it helps to improve space utilization.

[0051] In some alternative embodiments, the guide sleeve further includes:

[0052] The straight section is connected to the guide section on the side near the second connector, and the straight section can be clearance-fitted with the first connector.

[0053] Beneficial effects: With this setting, the inner diameter of the straight section is slightly larger than the outer diameter of the first connector, which ensures that the first connector can be smoothly inserted into the straight section and move within the straight section without obstruction. The first connector is a blind plug or blind socket, and the deviation between the inner diameter of the straight section and the first connector can be compensated by the floating amount of the first connector itself.

[0054] In some alternative embodiments, the first connector and the second connector are used to deliver coolant, and the inner circumference of the guide sleeve is also provided with a liquid storage tank, which is connected to the insertion points of the first connector and the second connector.

[0055] Beneficial effects: With this configuration, if coolant leaks during the mating process of the blind-mating connector, the coolant can be stored in the reservoir, thus preventing coolant leakage from coming into contact with the server's internal circuitry, causing short circuits, corrosion, performance degradation, or even equipment damage, affecting the normal operation of the server, or leading to data loss and service interruption.

[0056] In addition, the liquid storage tank can reduce the amount of material required for the guide sleeve and reduce the weight of the guide sleeve itself.

[0057] In some alternative embodiments, the liquid storage tank is an annular groove arranged circumferentially along the guide sleeve.

[0058] In some alternative implementations, the blind-mating connector further includes:

[0059] The second sealing ring is sleeved on the outer periphery of the first plug-in. When the first plug-in and the second plug-in are inserted, the second sealing ring is located on the side of the liquid storage tank away from the floating module and is sandwiched between the first plug-in and the guide sleeve.

[0060] Beneficial effect: With this configuration, the second sealing ring can seal the gap between the first connector and the guide sleeve, thereby further reducing the risk of coolant leakage and contact with the internal circuitry of the server.

[0061] In some alternative implementations, the blind-mating connector further includes:

[0062] A limiting ring groove is provided along the circumference of the first connector, and the second sealing ring is limited within the limiting ring groove.

[0063] Beneficial effect: With this setting, the limiting ring groove can limit the second sealing ring on the second plug-in, thereby preventing the second sealing ring from slipping off during the insertion of the first plug-in and the second plug-in, thus avoiding loss of sealing effect.

[0064] In some alternative implementations, the blind-mating connector further includes:

[0065] The fixed post has a second connector connected to its inner circumference, and a guide sleeve connected to its outer circumference.

[0066] Beneficial effects: By connecting the guide sleeve and the second connector simultaneously with a fixed post, the structure of the blind-fit connector can be made simpler and more compact, and it also helps to improve the coaxiality of the second connector and the guide sleeve.

[0067] In some alternative embodiments, the outer periphery of the fixing post is provided with a first external thread, and the inner periphery of the guide sleeve is provided with a first internal thread, the first external thread being capable of threaded connection with the first internal thread; and / or,

[0068] The inner circumference of the fixed column is provided with a second internal thread, and the outer circumference of the second plug-in is provided with a second external thread. The second internal thread can be threadedly connected with the second external thread.

[0069] In some alternative embodiments, a first anti-rotation surface is provided on the outer periphery of the fixed column, and a second anti-rotation surface is provided on the outer periphery of the second connector.

[0070] Beneficial effect: With this configuration, when it is necessary to connect the fixing post to the second connector, the operator can put the fixing post on the second connector and pinch the first anti-rotation surface and the second anti-rotation surface with both hands respectively, drive the first anti-rotation surface and the second anti-rotation surface to move in opposite directions, thereby threading the fixing post to the second connector.

[0071] In some alternative implementations, the first connector includes one of a blind plug and a blind socket, and the second connector includes the other of a blind plug and a blind socket.

[0072] Beneficial effects: When the first connector and the second connector are respectively a blind plug and a blind socket, they have a certain amount of floating capacity and can absorb some of the system error through their floating capacity, thereby improving the reliability of the blind connector.

[0073] Thirdly, this application also provides a liquid cooling system, comprising:

[0074] Electronic devices awaiting liquid cooling;

[0075] Coolant supply equipment;

[0076] The blind-mating connector provided in the second aspect of this application has a floating module disposed on one of the electronic device to be liquid-cooled and the coolant supply device, and a second mating member disposed on the other of the electronic device to be liquid-cooled and the coolant supply device.

[0077] Beneficial effects: The coolant supply equipment can supply coolant to the electronic devices to be liquid cooled through blind-mating connectors, and transfer and disperse the heat generated during equipment operation to maintain the normal operating temperature of the equipment and prevent damage caused by overheating.

[0078] Furthermore, the liquid cooling system of this application embodiment includes or uses the blind mating connector of the second aspect of this application, thus having its beneficial effect, namely, it can overcome the problem in the related art that the floating module of the blind mating connector cannot be used in the working condition where either the pin or the plug of the blind mating connector is tilted, which easily causes the plug and the pin to fail to mate smoothly, easily causes poor contact, damage to the plug or the pin, etc. Therefore, the connection between the electronic device to be liquid cooled and the coolant supply equipment is more reliable and smooth.

[0079] Furthermore, because the blind-mating connector of the liquid cooling system in this embodiment has a compact structure and low cost, it can avoid exacerbating the space constraints around electronic devices caused by blind-mating connectors. In addition, the liquid cooling system has a simple structure, is easy to assemble, and is safe and reliable to use, making it easy to implement and promote its application.

[0087] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0088] As the power of integrated circuits in electronic devices gradually increases, traditional air cooling is increasingly unable to meet the heat dissipation requirements of integrated circuits. Liquid cooling technology, as an emerging heat dissipation method, offers higher heat dissipation efficiency and lower noise levels compared to traditional air cooling. It achieves rapid heat conduction and dissipation through direct contact between a liquid medium and the heat source, effectively reducing equipment temperature and improving equipment stability and reliability. Liquid cooling technology is particularly important in data centers and high-performance computing, especially in high-computing applications such as artificial intelligence and big data analytics, where it demonstrates enormous potential and advantages.

[0089] The electronic devices to be cooled and the coolant supply equipment need to be connected through fluid connectors to enable and disconnect the fluid flow channel.

[0090] Fluid connectors, taking blind-mating connectors as an example, mainly consist of a plug and a socket. One of the plug and socket is mounted on a guide module. The guide module ensures that the connectors can mate without manual alignment, achieving accurate connection even when invisible or inaccessible to the naked eye. Furthermore, blind-mating connectors typically have a small float, allowing for a certain range of axial and radial deviations to accommodate minor errors during installation and ensure connection reliability.

[0091] During the connection process of the liquid cooling system, the operator can move the electronic equipment to be liquid-cooled, bringing it closer to or away from the liquid cooling supply equipment, thereby allowing the plug and socket of the blind-mating connector to mate or separate. Since the plug and socket of the blind-mating connector do not require operator intervention during the mating process, a guide module is needed between the plug and socket to achieve proper positioning.

[0092] However, in actual use, the floating amount of the blind-mating connector itself is often insufficient to absorb the deviation in the entire liquid cooling system. Therefore, it is necessary to install one of the blind-mating connector plug and socket (for ease of description, the plug and socket will be referred to as connectors in the following text) on the floating module, and provide additional floating amount through the floating module, so as to ensure that the blind-mating plug can absorb the deviation of the liquid cooling system and prevent the plug and socket from failing to connect due to excessive deviation or being damaged due to excessive stress.

[0093] In related technologies, floating modules for blind-mating connectors typically include a base and a connector disposed within the base. Multiple springs are connected to the outer periphery of the connector and are movably connected to the base via these springs. With this configuration, during the docking of the electronic device to be liquid-cooled with the coolant supply equipment, the floating module first contacts the guide module. Under the force of the guide module, the springs deform, causing the connector mounted on the floating connector to move, thereby ensuring that the connectors on the electronic device to be liquid-cooled and the coolant supply equipment are centered and aligned.

[0094] However, this floating module can only absorb deviations in the axial and radial directions along the blind-mating connector. When either the pin or the plug of the blind-mating connector is tilted, the floating module cannot absorb this mating deviation, which can easily cause the plug and pin to fail to be properly inserted. Even if forced to insert, it can easily cause poor contact and damage to the plug or pin.

[0095] In addition, this type of floating module requires elastic elements to be set around the connector, which results in a large number of elastic elements required for the floating module, making the structure of the floating module more complex and the cost higher.

[0096] Secondly, in order to ensure that the floating module has a large floating range, it is necessary to ensure that the elastic components around the floating module have a large compression space, which results in the overall size of the floating module being large.

[0097] Some embodiments of this application are described below with reference to Figures 1 and 2.

[0098] According to an embodiment of this application, a floating module for a blind-mating connector is provided, comprising a body 1, a first plug member 2, a return slider 3, and an elastic member 5. A guide channel 101 is formed within the body 1, and a first flange 102 and a second flange 103 are formed on the inner wall of the guide channel 101, spaced apart axially along the guide channel 101. The first plug member 2 is at least partially disposed within the guide channel 101, and an annular protrusion 201 is formed on the outer periphery of the first plug member 2, located between the first flange 102 and the second flange 103. The return slider 3 is movably disposed within the guide channel 101 and surrounds the first plug member 2. The return slider 3 abuts against the side of the annular protrusion 201 near the second flange 103. A guide slope 4 is formed between the return slider 3 and the annular protrusion 201, and the guide slope 4 is inclined in a direction away from the axis of the guide channel 101 along the direction near the first flange 102. The elastic element 5 is disposed in the guide channel 101 and supported between the return slider 3 and the second flange 103.

[0099] In the use of the floating module of this application embodiment, when the first connector 2 is connected to the corresponding second connector 6, if the first connector 2 and the second connector 6 deviate along the axial or radial direction, or if the first connector 2 and the second connector 6 are set at an angle, the first connector 2 of the floating module can contact the guide module. The guide module can apply a force to the first connector 2, and this force can be transmitted to the return slider 3 through the annular protrusion 201, thereby pushing the return slider 3 to move backward. At the same time, the first connector 2 moves along the direction of the force, thereby realizing the floating of the first connector 2, so as to ensure that the first connector 2 can accurately connect with the corresponding second connector 6, and the angular deviation of the first connector 2 can be absorbed by the elastic member 5.

[0100] Furthermore, since the guide ramp 4 is configured to be inclined in a direction away from the axis of the guide channel 101 along the direction close to the first flange 102, the first plug 2 can move axially relative to the guide channel 101, move radially relative to the guide channel 101, and be set at an angle to the axis of the guide channel 101.

[0101] With this configuration, regardless of whether the pins and plugs of the blind-mating connector deviate along the axial or radial direction of the blind-mating connector, or whether either the plug or pin of the blind-mating connector tilts, the floating module of this application embodiment can absorb the error between the pins and plugs of the blind-mating connector, thereby ensuring that the pins and plugs of the blind-mating connector can be smoothly inserted into place without damaging the blind-mating connector.

[0102] Furthermore, in this embodiment of the application, the floating module cooperates with the return slider 3 through an elastic element 5, ensuring that the first plug-in 2 has a large floating amount in multiple directions. This reduces the number of elastic elements 5 required for the floating module, lowers the cost of the floating module, and makes the structure of the floating module more compact, reducing the space required by the floating module.

[0103] Therefore, the floating module of this application embodiment can overcome the problems in related technologies where the floating module of the blind mating connector cannot be applied to working conditions where either the pin or the plug of the blind mating connector is tilted, which easily causes the plug and pin to fail to mate smoothly, easily leads to poor contact, and damage to the plug or pin. Furthermore, it can reduce the number of elastic elements 5 required by the floating module, lowering the cost of the floating module, and the floating module requires less space and has a compact structure. In addition, the above-mentioned floating module has a simple structure, is easy to assemble, and is safe and reliable to use, making it easy to implement and promote its application.

[0104] The first connector 2 is used to connect with the second connector 6. One of the first connector 2 and the second connector 6 can be a blind plug, and the other of the first connector 2 and the second connector 6 can be a blind socket.

[0105] Furthermore, in some embodiments of this application, the guide slope 4 is arranged around the outer periphery of the first connector 2, and the center line of the guide slope 4 coincides with the axis of the guide channel 101.

[0106] With this configuration, when the first connector 2 and the second connector 6 are plugged into each other, the return slider 3 can apply a force to the annular protrusion 201 of the first connector 2 through the guide slope 4. This force can be decomposed into radial and axial components along the guide channel 101. When the first connector 2 and the second connector 6 are separated, the floating module can separate from the guide module, thereby losing the force applied by the guide module. At this time, the force applied by the return slider 3 to the annular protrusion 201 in the radial direction along the guide channel 101 can drive the first connector 2 to be centered in the guide sleeve 7.

[0107] Furthermore, in some embodiments of this application, the guide slope 4 includes a first annular surface and a second annular surface. The first annular surface is disposed on the annular protrusion 201. The second annular surface is disposed on the return slider 3, and the slopes of the first and second annular surfaces are the same.

[0108] This design ensures that the movement of the annular protrusion 201 relative to the return slider 3 is smoother.

[0109] It should be noted that the slope of the first annular surface and the second annular surface are the same, which means that the angle formed by the first annular surface and the second annular surface is between -1° and 1°.

[0110] As an alternative implementation, the first annular surface and the second annular surface may also be configured to be at a certain angle.

[0111] As another alternative implementation, the guide slope 4 may include only a first annular surface disposed on the annular protrusion 201, or the guide slope 4 may include only a second annular surface disposed on the return slider 3.

[0112] Furthermore, in some embodiments of this application, the first connector 2 includes a connector segment 202 and a connecting segment 203. The connector segment 202 is located outside the main body 1 and on the side of the annular protrusion 201 away from the elastic member 5. The connecting segment 203 connects the connector segment 202 and the annular protrusion 201. The diameter of the connector segment 202 is larger than the inner diameter of the first flange 102, and the diameter of the connecting segment 203 is less than or equal to the inner diameter of the first flange 102.

[0113] With this configuration, when the first connector 2 has been inserted into the second connector 6, but the liquid-cooled electronic device has not yet been moved to a fixed position, the operator can continue to push the liquid-cooling device along the insertion direction of the first connector 2 and the second connector 6. The diameter of the connecting section 203 is less than or equal to the inner diameter of the first flange 102, and can be inserted into the guide channel 101 and compress the elastic element 5. Thus, the elastic element 5 absorbs the error of the system in the axial direction, ensuring that the electronic device can be installed smoothly without damaging the blind-fit connector.

[0114] In the description of the embodiments of this application, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0115] The return slider 3 can be an integral structure. As a changeable implementation method, the return slider 3 is composed of multiple guide plates spliced ​​together. Multiple guide petals are arranged sequentially along the circumference of the guide channel 101. The side surface of the multiple guide petals facing the first flange 102 can form a second annular surface.

[0116] Furthermore, in some embodiments of this application, the plug-in segment 202 includes a plug connector 2021, a retaining sleeve 2022, and a first sealing ring 2023. The plug connector 2021 can be either a blind-plug plug or a blind-plug socket. Exemplarily, in the embodiment shown in FIG5, the plug connector 2021 is a blind-plug plug. The retaining sleeve 2022 is fitted onto the outer periphery of the plug connector 2021, and the connecting segment 203 includes a connecting tube communicating with the retaining sleeve 2022. The first sealing ring 2023 is fitted onto the outside of the plug connector 2021 and sandwiched between the plug connector 2021 and the retaining sleeve 2022.

[0117] With this configuration, the blind plug, the fixing sleeve 2022, and the connecting pipe are connected in sequence, which can be used to transfer coolant. The first sealing ring 2023 can be used to improve the sealing between the plug 2021 and the fixing sleeve 2022 to prevent coolant leakage.

[0118] The connecting section 203 and the annular protrusion 201 can be either integrally formed or configured as separate structures, and are interconnected. Exemplarily, in some optional embodiments, the connecting section 203 can be bonded to or threadedly connected to the annular protrusion 201. The connecting pipe can be used to connect the hoses forming the coolant channel. Exemplarily, as shown in FIG5, the end of the connecting pipe away from the first flange 102 extends from the guide channel 101, and an anti-slip protrusion 2031 is formed on its outer periphery. The anti-slip protrusion 2031 can interfere with the pipes of the liquid cooling system when the connecting pipe is inserted into them, thereby increasing the friction between the pipes, preventing pipe slippage, and also absorbing and dispersing the force to a certain extent, avoiding connection failure or damage due to localized concentrated force. Furthermore, the anti-slip protrusion 2031 can also improve the sealing between the pipes, preventing coolant leakage, which could affect the cooling effect or even contact with the wiring inside the server rack.

[0119] The number of anti-slip protrusions 2031 can be one or more. For example, in the embodiment shown in Figures 1 and 2, the number of anti-slip protrusions 2031 is three, and they are evenly distributed at the end of the connecting pipe. This can provide sufficient sealing for the connection between pipes without increasing the manufacturing cost of the connecting pipe.

[0120] The coolant can be water, or a water-based, diol-based, dielectric, or refrigerant type. Water-based coolants have good heat transfer properties, but require the addition of antifreeze agents such as ethylene glycol or propylene glycol to adapt to low-temperature environments. Diol-based coolants have good antifreeze properties, but increased viscosity can affect pump operating costs. Dielectric liquids have low conductivity, preventing short circuits in electronic equipment, but are relatively expensive. Refrigerants typically have high latent heat and low pump power consumption, but may decompose at high temperatures.

[0121] Although in this application embodiment, the blind connector 2021 is a fluid blind connector 2021 for transmitting coolant, in embodiments not shown in the drawings, the blind connector 2021 can also be selected as a power blind connector 2021, which can achieve correct docking of the power connector when it is not visible or difficult to access.

[0122] The first sealing ring 2023 is preferably, but not limited to, made of materials such as rubber or silicone.

[0123] Furthermore, in some embodiments of this application, the elastic member 5 includes a spring surrounding the first connector 2; a first anti-detachment groove 301 is formed on the return slider 3, and the first end of the spring is limited in the first anti-detachment groove 301. A second anti-detachment groove 1031 is formed on the second flange 103, and the second end of the spring is limited in the second anti-detachment groove 1031.

[0124] The first anti-slip ring groove 301 and the second anti-slip ring groove 1031 can be used to limit the spring, prevent the spring from slipping, and ensure that the spring can continuously support the return slider 3. At the same time, the first anti-slip ring groove 301 and the second anti-slip ring groove 1031 can also work together with the inner wall of the guide channel 101 to restrict the spring from stretching or contracting in the direction perpendicular to the compression direction, and prevent the spring from bending.

[0125] As a variable implementation, the elastic element 5 includes multiple springs, which are spaced apart circumferentially along the first plug 2. Multiple spring limiting grooves are formed on the return slider 3 and the second flange 103, and the ends of the springs are located in the spring limiting grooves.

[0126] Furthermore, in some embodiments of this application, the main body 1 includes a base 104. A first flange 102 is disposed on the base 104, and a second flange 103 is detachably connected to the end of the base 104 away from the first flange 102.

[0127] With this configuration, the base 104 and the second flange 103 can be separated from each other during the assembly process, so that the operator can sequentially place the first connector 2, the return slider 3 and the spring into the guide channel 101, and then connect the second flange 103 to the base 104, thereby limiting the first connector 2, the return slider 3 and the spring within the guide channel 101.

[0128] In some embodiments, after assembly, the spring is in a compressed state, which can provide a stable thrust for the return slider 3.

[0129] It should be noted that the specific shape of the base 104 is not limited in the embodiments of this application. For example, in the embodiment shown in FIG1, the base 104 is a cylindrical structure.

[0130] As a possible implementation, in some embodiments not shown in the figures, the base 104 may also be a prism-shaped cylinder, such as a prism with a triangular, square, pentagonal or hexagonal cross-section.

[0131] As a possible implementation, in an embodiment not shown in the figures, a second flange 103 is formed on a base 104, and a first flange 102 is detachably connected to the end of the base 104 away from the second flange 103.

[0132] The base 104 and the second flange 103 are preferably, but not limited to, connected to each other by means of snap-fit, riveting, threaded connection or welding. For example, in the embodiment shown in FIG1, a first connecting edge and a second connecting edge are formed on the outer periphery of the base 104 and the second flange 103, respectively. A first connecting hole and a second connecting hole are formed on the first connecting edge and the second connecting edge, respectively. The fastener can pass through the second connecting hole and connect to the base 104.

[0133] It should be noted that, in the embodiments of this application, the specific shapes of the first connecting edge and the second connecting edge are not limited. For example, in the embodiment shown in FIG1, both the first connecting edge and the second connecting edge are square edges. As a variable implementation, the first connecting edge and the second connecting edge can also be annular edges or elliptical edges, etc. When the first connecting edge and the second connecting edge are selected as annular edges, the first connecting hole can be selected to be evenly distributed along the circumference of the first connecting edge, and the second connecting hole can be selected to be evenly distributed along the circumference of the second connecting edge.

[0134] When the first connecting edge and the second connecting edge are elliptical, the first connecting hole can be disposed on the major axis of the first connecting edge and symmetrically distributed on both sides of the guide channel 101. The second connecting hole can be disposed on the major axis of the second connecting edge and symmetrically distributed on both sides of the guide channel 101.

[0135] Furthermore, in some embodiments of this application, the inner diameter of the first flange 102 is smaller than the outer diameter of the return slider 3.

[0136] This design prevents the return slider 3 from slipping out of the guide channel 101.

[0137] In some embodiments, the inner diameter of the first flange 102 is smaller than the outer diameter of the annular protrusion 201.

[0138] According to an embodiment of this application, another aspect provides a blind-mating connector, including a floating module and a second plug-in 6. The second plug-in 6 is capable of being plugged into a first plug-in 2.

[0139] Embodiment 2 of this application will now be described with reference to Figures 1 to 5.

[0140] The blind-mating connector of the second aspect of this application includes or uses the floating module of the first aspect of this application, and therefore has the following advantages: The blind-mating connector of the embodiments of this application can overcome the problems in related technologies where the floating module of the blind-mating connector cannot be used in situations where either the pin or the plug of the blind-mating connector is tilted, easily causing the plug and pin to fail to mate smoothly, easily causing poor contact, damage to the plug or pin, etc. Furthermore, it can reduce the number of elastic elements 5 required by the floating module, thereby reducing the cost of the blind-mating connector. The blind-mating connector also requires less space and has a compact structure. In addition, the above-mentioned floating module has a simple structure, is easy to assemble, and is safe and reliable to use, facilitating implementation and widespread application.

[0141] Furthermore, in some embodiments of this application, the blind-mating connector further includes a guide sleeve 7. The second mating member 6 is disposed within the guide sleeve 7, and the guide sleeve 7 is provided with a guide section 701, the inner diameter of which gradually decreases along the direction approaching the second mating member 6.

[0142] In related technologies, the guide module of a blind mating connector generally includes multiple guide pins disposed on the outer periphery of the second mating member 6. The floating module is correspondingly provided with positioning holes that correspond to the guide pins. When the floating module and the guide module are mated, the guide pins can be inserted into the positioning holes, thereby enabling the plug and the pin to be accurately mated.

[0143] However, the guide pins need to be set in two or more, which increases the volume of the floating module and exacerbates the space constraints of the electronic device.

[0144] The blind-mating connector of this application embodiment includes a guide sleeve 7 and a second plug member 6 disposed in the guide sleeve 7. When the first plug member 2 is connected to the corresponding second plug member 6, when the first plug member 2 and the second plug member 6 deviate along the axial and radial directions, and the first plug member 2 and the second plug member 6 are set at an angle, the first plug member 2 of the floating module can contact the guide section 701 of the guide sleeve 7. The guide section 701 can apply a force to the first plug member 2. The force can be transmitted to the return slider 3 through the annular protrusion 201, thereby pushing the return slider 3 to move backward. At the same time, the first plug member 2 moves along the direction of the force, thereby realizing the floating of the first plug member 2, so that the first plug member 2 can accurately dock with the second plug member 6.

[0145] Moreover, compared to the scheme that uses guide pins and guide holes, the structure is simpler and more compact, and it helps to improve space utilization.

[0146] Furthermore, in some embodiments of this application, the guide sleeve 7 further includes a straight section 703. The straight section 703 is connected to the side of the guide section 701 near the second connector 6, and the straight section 703 can be clearance-fitted with the first connector 2.

[0147] With this configuration, the inner diameter of the straight section 703 is slightly larger than the outer diameter of the first connector 2, ensuring that the first connector 2 can be smoothly inserted into the straight section 703 and move within the straight section 703 without obstruction. In some embodiments, the first connector 2 is a blind plug or blind socket, and the deviation between the inner diameter of the straight section 703 and the first connector 2 can be compensated by the floating amount of the first connector 2 itself.

[0148] As an alternative implementation, the guide sleeve 7 may also be configured to not have a straight section 703.

[0149] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0150] Furthermore, in some embodiments of this application, the first connector 2 and the second connector 6 are used to transport coolant, and the inner circumference of the guide sleeve 7 is also provided with a liquid storage tank 702, which is connected to the insertion points of the first connector 2 and the second connector 6.

[0151] With this design, if coolant leaks during the mating process of the blind-mating connector, the coolant can be stored in the reservoir 702, thus preventing coolant leakage from coming into contact with the server's internal circuitry, causing short circuits, corrosion, performance degradation, or even equipment damage, affecting the normal operation of the server, or leading to data loss and service interruption.

[0152] In addition, the liquid storage tank 702 can reduce the amount of material required for the guide sleeve 7 and reduce the weight of the guide sleeve 7 itself.

[0153] As a variation of the implementation, in some embodiments not shown in the accompanying drawings, the side wall of the reservoir 702 near the guide section 701 is set to be inclined toward the axis of the second connector 6 along the direction in which the second connector 6 and the first connector 2 are inserted into each other, so that the operator can tilt the guide sleeve 7 to discharge the coolant stored in the reservoir 702.

[0154] As another alternative implementation, a liquid outlet is formed on the outer periphery of the guide sleeve 7, which is connected to the liquid storage tank 702. The liquid outlet is provided with a plug, which the operator can remove to drain the coolant from the liquid storage tank 702.

[0155] Furthermore, in some embodiments of this application, the liquid storage tank 702 is an annular groove arranged circumferentially along the guide sleeve 7.

[0156] As an alternative implementation, the liquid storage tank 702 may also be configured to be located only below the connection point between the first connector 2 and the second connector 6.

[0157] Furthermore, in some embodiments of this application, the blind-mating connector further includes a second sealing ring. The second sealing ring is sleeved on the outer periphery of the first plug-in 2. When the first plug-in 2 and the second plug-in 6 are plugged in, the second sealing ring is located on the side of the liquid storage tank 702 away from the floating module and is sandwiched between the first plug-in 2 and the guide sleeve 7.

[0158] With this configuration, the second sealing ring can seal the gap between the first connector 2 and the guide sleeve 7, thereby further reducing the risk of coolant leakage and contact with the internal circuitry of the server.

[0159] The second sealing ring is preferably, but not limited to, made of materials such as rubber or silicone.

[0160] Furthermore, in some embodiments of this application, the blind-mating connector further includes a limiting ring groove. The limiting ring groove is disposed along the circumference of the first plug member 2, and the second sealing ring is contained within the limiting ring groove.

[0161] With this setting, the limiting ring groove can limit the second sealing ring on the second plug-in 6, thereby preventing the second sealing ring from slipping out during the insertion of the first plug-in 2 and the second plug-in 6, which would result in loss of sealing effect.

[0162] As an alternative implementation, the second sealing ring is bonded to the outer periphery of the second connector 6.

[0163] As in some alternative implementations, a limiting annular groove is formed on the inner circumference of the guide sleeve 7, and the second sealing ring is confined within the limiting annular groove.

[0164] As another alternative implementation, the second sealing ring is bonded to the inner circumference of the guide sleeve 7.

[0165] Furthermore, in some embodiments of this application, the blind-mating connector further includes a fixing post 8. The second insertion member 6 is connected to the inner periphery of the fixing post 8, and the guide sleeve 7 is connected to the outer periphery of the fixing post 8.

[0166] By connecting the guide sleeve 7 and the second plug 6 simultaneously through a fixed post 8, the structure of the blind-fit connector can be made simpler and more compact, and it also helps to improve the coaxiality between the second plug 6 and the guide sleeve 7.

[0167] Furthermore, in some embodiments of this application, the outer periphery of the fixed column 8 is provided with a first external thread, and the inner periphery of the guide sleeve 7 is provided with a first internal thread, and the first external thread can be threadedly connected with the first internal thread.

[0168] The inner circumference of the fixed column 8 is provided with a second internal thread, and the outer circumference of the second plug-in 6 is provided with a second external thread. The second internal thread can be threadedly connected with the second external thread.

[0169] It should be noted that in this embodiment, the specific shape of the guide sleeve 7 is not limited. For example, in the embodiment shown in FIG3, the guide sleeve 7 is a cylinder.

[0170] As an alternative implementation, in some embodiments not shown in the accompanying drawings, the guide sleeve 7 may also be selected as a prismatic cylinder, such as a prism with a triangular, square, pentagonal, or hexagonal cross-section.

[0171] When the guide sleeve 7 is a prismatic cylinder, the outer surface of the prismatic cylinder can serve as an anti-rotation surface, making it easier for the operator to thread the guide sleeve 7 to the fixed post 8. Preferably, the two adjacent sides of the prismatic cylinder have a rounded transition to avoid injury to the operator's hands.

[0172] As an alternative implementation, the fixing column 8 can also be connected to the guide sleeve 7 and the second connector 6 by means of welding, snap-fitting or bolting.

[0173] Furthermore, in some embodiments of this application, a first anti-rotation surface 801 is provided on the outer periphery of the fixed column 8, and a second anti-rotation surface 601 is provided on the outer periphery of the second plug-in 6.

[0174] With this configuration, when it is necessary to connect the fixing post 8 to the second connector 6, the operator can put the fixing post 8 on the second connector 6, and hold the first anti-rotation surface 801 and the second anti-rotation surface 601 with both hands respectively, and drive the first anti-rotation surface 801 and the second anti-rotation surface 601 to move in opposite directions, thereby threading the fixing post 8 to the second connector 6.

[0175] For example, in the embodiment shown in FIG3, a first hexagonal nut is formed on the fixing post 8, a first anti-rotation surface 801 is formed on the first hexagonal nut, and a second hexagonal nut is formed on the second connector 6. A second anti-rotation surface 601 is formed on the second hexagonal nut.

[0176] As an alternative implementation, the first anti-rotation surface 801 and the second anti-rotation surface 601 may also be selected as frosted surfaces.

[0177] Furthermore, in some embodiments of this application, the first connector 2 includes one of a blind plug and a blind socket, and the second connector 6 includes the other of a blind plug and a blind socket.

[0178] When the first connector 2 and the second connector 6 are respectively a blind plug and a blind socket, they have a certain amount of floating capacity and can absorb some of the system error through their floating capacity, thereby improving the reliability of the blind connector.

[0179] According to an embodiment of this application, another aspect provides a liquid cooling system, including an electronic device to be liquid-cooled, a coolant supply device, and a blind-mating connector according to the second aspect of this application. The floating module of the blind-mating connector is disposed on one of the electronic device to be liquid-cooled and the coolant supply device, and the second mating member 6 of the blind-mating connector is disposed on the other of the electronic device to be liquid-cooled and the coolant supply device.

[0180] The electronic devices to be liquid-cooled are preferably, but not limited to, servers, server racks, storage devices, computers, or batteries. Coolant supply equipment refers to devices used to supply and circulate coolant, typically including components such as cooling towers, coolers, water pumps, expansion tanks, and piping systems. Coolant supply equipment supplies coolant to the electronic devices to be liquid-cooled via blind-mating connectors and transfers and disperses the heat generated during device operation to maintain the normal operating temperature of the equipment and prevent damage caused by overheating.

[0181] When the electronic device to be liquid-cooled is a server rack, the first connector 2 can be optionally installed on the cooling medium supply and return manifold of the server rack.

[0182] Furthermore, the liquid cooling system of this application embodiment includes or uses the blind mating connector of the second aspect of this application, thus having its beneficial effect, namely, it can overcome the problem in the related art that the floating module of the blind mating connector cannot be used in the working condition where either the pin or the plug of the blind mating connector is tilted, which easily causes the plug and the pin to fail to mate smoothly, easily causes poor contact, damage to the plug or the pin, etc. Therefore, the connection between the electronic device to be liquid cooled and the coolant supply equipment is more reliable and smooth.

[0183] Furthermore, because the blind-mating connector of the liquid cooling system in this embodiment has a compact structure and low cost, it can avoid exacerbating the space constraints around electronic devices caused by blind-mating connectors. In addition, the liquid cooling system has a simple structure, is easy to assemble, and is safe and reliable to use, making it easy to implement and promote its application.

[0184] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily make changes or modifications within the technical scope disclosed in this application, and such changes or modifications should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims. As long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
