Description

Technical Field

[0001] The invention relates to the technical field of mechanism design, and in particular to a floating module, a blind-plug connector and a liquid cooling system. Background Art

[0002] A blind-mate connector is a device that can achieve precise connection in poor or uncertain sight conditions. In the related art, in order to enhance the blind-mate connector's ability to absorb docking deviation, one of the blind-mate connector's socket and pin is usually mounted on a floating module.

[0003] However, the floating module can only move along the docking direction and perpendicular to the docking direction. When either the pin or the plug of the blind-mate connector is tilted, the floating module cannot absorb the docking deviation, which may easily cause the plug and the pin to be unable to be plugged in smoothly. Even if they are forced to be plugged in, loose contact may occur, which may easily damage the plug or the pin. Summary of the invention

[0004] In view of this, the present invention provides a floating module, a blind-mate connector and a liquid cooling system to solve the problem in the related art that the floating module of the blind-mate connector cannot be applied to the working condition where either the pin or the plug of the blind-mate connector is tilted, which may easily cause the plug and the pin to be unable to dock smoothly, and even if forced to dock, it may easily cause loose contact and damage the plug or the pin.

[0005] In a first aspect, the present invention provides a floating module for a blind-mate connector, comprising:

[0006] A main body, wherein a guide channel is formed in the main body, and a first flange and a second flange are formed on an inner wall of the guide channel and are spaced apart along the axial direction of the guide channel;

[0007] A first plug-in connector is at least partially disposed in the guide channel, an annular convex portion is formed on the outer periphery of the first plug-in connector, and the annular convex portion is located between the first flange and the second flange;

[0008] A return slider is movably arranged in the guide channel and is arranged around the outside of the first connector. The return slider abuts against a side of the annular protrusion close to the second flange. A guide slope is formed between the return slider and the annular protrusion. In a direction close to the first flange, the guide slope is inclined in a direction away from the axis of the guide channel.

[0009] The elastic member is arranged in the guide channel and supported between the return slider and the second flange.

[0010] Beneficial effect: During use of the floating module of the embodiment of the present invention, when the first connector is connected to the corresponding second connector, when the first connector and the second connector deviate in the axial and radial directions, 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, and the guide module can apply a force to the first connector, and the force can be transmitted to the return slider through the annular protrusion, thereby pushing the return slider to move backward, and at the same time, the first connector moves in the direction of the force to achieve the floating of the first connector, so as to ensure that the first connector can be accurately connected to the corresponding second connector, and the angular deviation of the first connector can be absorbed by the elastic member.

[0011] Since the guide slope is configured to be inclined in a direction close to the first flange and in a direction away from the axis of the guide channel, the first connector can move axially along the guide channel relative to the guide channel, move radially along the guide channel relative to the guide channel, and can also be set at an angle to the axial direction of the guide channel.

[0012] By such a configuration, no matter whether the pin and the plug of the blind-mate connector deviate along the axial or radial direction of the blind-mate connector, or any of the plug and the pin of the blind-mate connection tilts, the floating module of the embodiment of the present application can absorb the error between the pin and the plug of the blind-mate connector, thereby ensuring that the pin and the plug of the blind-mate connector can be smoothly plugged into place without damaging the blind-mate connector.

[0013] In addition, the floating module of the embodiment of the present invention cooperates with the return slider through an elastic member to ensure that the first connector has a large floating amount in multiple directions, thereby reducing the number of elastic members required for the floating module, reducing the cost of the floating module, and making the structure of the floating module more compact, thereby reducing the space required for the floating module.

[0014] Therefore, the floating module of the embodiment of the present invention can overcome the problem in the related art that the floating module of the blind-plug connector cannot be applied to the working condition where any of the pins and plugs of the blind-plug connector are tilted, which easily causes the plug and the pin to be unable to dock smoothly, which easily causes loose contact and damage to the plug or the pin, and can reduce the number of elastic parts required for the floating module, reduce 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, is safe and reliable to use, and is easy to implement and promote.

[0015] In an optional embodiment, the guiding slope is arranged around the outer circumference of the first connector, and the center line of the guiding slope coincides with the axis of the guiding channel.

[0016] Beneficial effect: Through such an arrangement, when the first connector and the second connector are plugged into each other, the return slider can apply a force to the annular protrusion of the first connector through the guide bevel, and the force can be decomposed into radial and axial components along the guide channel. When the first connector and the second connector are separated, the floating module can be separated from the guide module, thereby losing the force applied by the guide module. At this time, the force in the radial direction of the guide channel applied by the return slider to the annular protrusion can drive the first connector to be centered in the guide sleeve.

[0017] In an optional embodiment, the guiding slope includes:

[0018] A first annular surface, disposed on the annular convex portion;

[0019] The second annular surface is arranged on the return sliding block, and the first annular surface and the second annular surface have the same inclination.

[0020] Beneficial effect: Through such an arrangement, it can be ensured that the movement of the annular protrusion relative to the return slider is smoother.

[0021] In an optional embodiment, the first connector includes:

[0022] The plug-in section is arranged outside the main body and located on a side of the annular protrusion away from the elastic member;

[0023] The connecting section is connected between the plug-in section and the annular protrusion. The diameter of the plug-in section is larger than the inner diameter of the first flange, and the diameter of the connecting section is smaller than or equal to the inner diameter of the first flange.

[0024] Beneficial effect: Through such an arrangement, when the first connector has been plugged into place with the second connector, but the electronic device to be liquid-cooled has not yet been moved to a fixed position, the operator can continue to push the liquid-cooling device to move along the plug-in direction of the first connector and the second connector. The diameter of the connecting section is less than or equal to the inner diameter of the first flange, and can be inserted into the guide channel and compress the elastic part, thereby ensuring that the electronic device can be smoothly installed in place without causing damage to the blind-plug connector.

[0025] In an optional embodiment, the plug-in section includes:

[0026] Plug connector;

[0027] A fixed sleeve is sleeved on the outer circumference of the plug connector, and the connecting section includes a connecting pipe, which is connected to the fixed sleeve;

[0028] The first sealing ring is sleeved outside the plug connector and clamped between the plug connector and the fixing sleeve.

[0029] Beneficial effect: Through such an arrangement, the blind plug, the fixing sleeve and the connecting pipe are connected in sequence and can be used to transmit the coolant. The first sealing ring can be used to improve the sealing between the plug connector and the fixing sleeve to prevent the coolant from leaking.

[0030] In an optional embodiment, the elastic member includes a spring disposed around the outside of the first plug-in member;

[0031] A first anti-slip ring groove is formed on the return slider, and the first end of the spring is limited in the first anti-slip ring groove; and / or,

[0032] A second anti-slip ring groove is formed on the second flange, and the second end of the spring is limited to the second anti-slip ring groove.

[0033] Beneficial effects: The first anti-slip ring groove and the second anti-slip ring groove can be used to limit the spring, prevent the spring from slipping, and ensure that the spring can continuously support the return slider. At the same time, the first anti-slip ring groove and the second anti-slip ring groove can also work together with the inner wall of the guide channel to limit the expansion and contraction of the spring in a direction perpendicular to the compression direction, thereby preventing the spring from bending.

[0034] In an optional embodiment, the main body includes:

[0035] The base is provided with a first flange, and the second flange is detachably connected to an end of the base away from the first flange.

[0036] Beneficial effect: Through such an arrangement, during the assembly process, the base and the second flange can be separated from each other, so that the operator can place 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.

[0037] In an optional embodiment, the inner diameter of the first flange is smaller than the outer diameter of the return slide.

[0038] Beneficial effect: By such an arrangement, the return slider can be prevented from slipping out of the guide channel.

[0039] In a second aspect, the present invention further provides a blind-mate connector, comprising:

[0040] The floating module provided by the first aspect of the present invention;

[0041] The second plug connector can be plugged with the first plug connector.

[0042] Beneficial effects: The blind-plug connector of the second invention of the present invention includes or uses the floating module of the first aspect of the present invention, and thus has its beneficial effects, namely: the blind-plug connector of the embodiment of the present invention can overcome the problem in the related art that the floating module of the blind-plug connector cannot be applied to any of the pins and plugs of the blind-plug connector when they are tilted, which easily causes the plug and the pin to be unable to dock smoothly, which easily causes loose contact and damages the plug or the pin, and can reduce the number of elastic parts required for the floating module, thereby reducing the cost of the blind-plug connector, and the space required for the blind-plug connector is small and the structure is compact. In addition, the floating module has a simple structure, is easy to assemble, is safe and reliable to use, and is easy to implement and promote.

[0043] In an optional embodiment, the blind-mate connector further comprises:

[0044] The second plug-in connector is arranged in the guide sleeve. The guide sleeve is provided with a guide section. The inner diameter of the guide section gradually decreases in the direction approaching the second plug-in connector.

[0045] Beneficial effects: In related technologies, the guide module of the blind-plug connector generally includes a plurality of guide pins arranged on the outer periphery of the second connector, and the floating module is correspondingly provided with positioning holes corresponding to the guide pins. When the floating module is connected to the guide module, the guide pins can be inserted into the positioning holes, so that the plug and the plug can be accurately connected.

[0046] However, two or more guide pins need to be provided, which increases the volume of the floating module and aggravates the space shortage of the electronic equipment.

[0047] The blind-plug connector of the embodiment of the present application includes a guide sleeve and a second connector arranged in the guide sleeve. When the first connector is connected to the corresponding second connector, when the first connector and the second connector deviate in the axial and radial directions, and the first connector and the second connector are arranged at an angle, the first connector of the floating module can contact the guide section of the guide sleeve, and the guide section can apply a force to the first connector. 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 connector moves in the direction of the force, thereby realizing the floating of the first connector, so that the first connector can be accurately connected to the second connector.

[0048] Moreover, compared with the scheme in which the guide pin and the guide hole are matched, the structure is simpler and more compact, and helps to improve the space utilization.

[0049] In an optional embodiment, the guide sleeve further includes:

[0050] The straight tube section is connected to a side of the guide section close to the second connector, and the straight tube section can be clearance-matched with the first connector.

[0051] Beneficial effect: Through such a configuration, the inner diameter of the straight tube section is slightly larger than the outer diameter of the first connector, which can ensure that the first connector can be smoothly inserted into the straight tube section and its movement in the straight tube section is not hindered. The first connector is a blind plug or a blind socket, and the deviation between the inner diameter of the straight tube section and the first connector can be compensated by the floating amount of the first connector itself.

[0052] In an optional embodiment, the first connector and the second connector are used to transport cooling liquid, and a liquid storage tank is also provided on the inner periphery of the guide sleeve, and the liquid storage tank is connected to the connection point between the first connector and the second connector.

[0053] Beneficial effect: Through such a setting, if coolant leaks during the docking process of the blind-mate connector, the coolant can be stored in the reservoir, thereby preventing the coolant from leaking and contacting the internal circuits of the server, causing short circuits, corrosion, performance degradation, or even equipment damage to the internal circuits of the server, affecting the normal operation of the server, or causing data loss and service interruption.

[0054] In addition, the liquid storage tank can also reduce the material required for the guide sleeve and reduce the weight of the guide sleeve itself.

[0055] In an optional embodiment, the liquid storage groove is an annular groove arranged along the circumference of the guide sleeve.

[0056] In an optional embodiment, the blind-mate connector further comprises:

[0057] The second sealing ring is sleeved on the outer periphery of the first connector. When the first connector is plugged with the second connector, 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 connector and the guide sleeve.

[0058] Beneficial effect: Through such an arrangement, 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 circuits of the server.

[0059] In an optional embodiment, the blind-mate connector further comprises:

[0060] The limiting ring groove is arranged along the circumference of the first plug-in connector, and the second sealing ring is limited in the limiting ring groove.

[0061] Beneficial effect: Through such an arrangement, the limiting ring groove can limit the second sealing ring on the second connector, thereby preventing the second sealing ring from slipping during the process of plugging the first connector and the second connector, resulting in loss of sealing effect.

[0062] In an optional embodiment, the blind-mate connector further comprises:

[0063] The second plug-in component is connected to the inner periphery of the fixed column, and the guide sleeve is connected to the outer periphery of the fixed column.

[0064] Beneficial effect: By connecting the guide sleeve and the second connector at the same time through a fixing column, the structure of the blind-plug connector can be made simpler and more compact, and it helps to improve the coaxiality of the second connector and the guide sleeve.

[0065] In an optional embodiment, a first external thread is provided on the outer circumference of the fixing column, a first internal thread is provided on the inner circumference of the guide sleeve, and the first external thread can be threadedly connected with the first internal thread; and / or,

[0066] A second internal thread is arranged on the inner circumference of the fixing column, and a second external thread is arranged on the outer circumference of the second plug-in component. The second internal thread can be threadedly connected with the second external thread.

[0067] In an optional embodiment, a first anti-rotation surface is provided on the outer circumference of the fixing column, and a second anti-rotation surface is provided on the outer circumference of the second connector.

[0068] Beneficial effect: Through such a configuration, when the fixing column needs to be connected to the second connector, the operator can put the fixing column 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 column to the second connector.

[0069] In an optional embodiment, the first connector includes one of a blind-mate plug and a blind-mate socket, and the second connector includes the other of a blind-mate plug and a blind-mate socket.

[0070] Beneficial effect: When the first connector and the second connector are a blind-mate plug and a blind-mate socket respectively, they themselves have a certain amount of floating, and can absorb a part of the system error through their own floating amount, thereby improving the reliability of the blind-mate connector.

[0071] In a second aspect, the present invention further provides a liquid cooling system, comprising:

[0072] Electronic devices to be liquid cooled;

[0073] Coolant supply equipment;

[0074] The blind-mate connector provided by the first aspect of the present invention has a floating module disposed on one of the electronic device to be liquid-cooled and the cooling liquid supply device, and a second connector of the blind-mate connector disposed on the other of the electronic device to be liquid-cooled and the cooling liquid supply device.

[0075] Beneficial effects: The coolant supply device can supply coolant to the electronic device to be liquid-cooled through a blind-plug connector, and transfer and disperse the heat generated when the device is in operation to maintain the normal operating temperature of the device and prevent damage caused by overheating.

[0076] In addition, the liquid cooling system of the embodiment of the present invention includes or uses the blind-plug connector of the second aspect of the present invention, and thus has its beneficial effect, namely, it can overcome the problem in the related art that the floating module of the blind-plug connector cannot be applied to the working condition where any of the pins and plugs of the blind-plug connector are tilted, which easily causes the plug and the pin to be unable to dock smoothly, easily causes loose contact, and damages the plug or the pin, and so on. Therefore, the connection between the electronic device to be liquid-cooled and the cooling liquid supply equipment is more reliable and smooth.

[0077] Since the blind-plug connector of the liquid cooling system of the embodiment of the present application is compact and low-cost, it can avoid aggravating the space shortage around the electronic device due to the blind-plug connector. In addition, the liquid cooling system has a simple structure, is easy to assemble, and is safe and reliable to use, which is convenient for implementation and promotion.

[0093] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0094] As the power of integrated circuits in electronic devices gradually increases, traditional air cooling is gradually unable to meet the heat dissipation needs of integrated circuits. Liquid cooling technology, as an emerging heat dissipation method, has higher heat dissipation efficiency and lower noise level compared to traditional air cooling. It achieves rapid heat conduction and dissipation through direct contact between the liquid medium and the heat source, effectively reducing the temperature of the equipment and improving the stability and reliability of the equipment. The application of liquid cooling technology is particularly important in data centers and high-performance computing fields, especially in situations with high computing power requirements such as artificial intelligence and big data analysis. Liquid cooling technology has shown great potential and advantages.

[0095] The electronic device to be liquid-cooled needs to be connected to the cooling liquid supply device through a fluid connector to achieve the conduction and disconnection of the fluid flow channel.

[0096] Taking the blind-mate connector as an example, the fluid connector mainly includes a plug and a socket, one of which is set on a guide module. The guide module can ensure that the connector can be docked without the need for staff to align it, and can still achieve accurate connection when it is not visible or touchable. In addition, the blind-mate connector usually has a small floating amount, which can allow axial and radial deviations within a certain range, so as to adapt to slight deviations during the installation process and ensure the reliability of the connection.

[0097] During the connection of the liquid cooling system, the operator can move the electronic device to be liquid cooled to be close to or away from the liquid cooling liquid supply device, so that the plug and the socket of the blind-plug connector can be connected or separated. Since the plug and the socket of the blind-plug connector do not require the participation of the staff in the alignment during the docking process, it is necessary to set a guide module between the plug and the socket of the blind-plug connector to realize the positioning between the plug and the socket.

[0098] However, in actual use, the floating amount of the blind-plug connector itself is often not enough to absorb the deviation in the entire liquid cooling system. Therefore, one of the blind-plug connector plug and socket (for the convenience of description, the plug and socket are collectively referred to as connectors in the following text) needs to be installed on the floating module, and additional floating amount is provided by the floating module to ensure that the blind-plug plug can absorb the deviation of the liquid cooling system and prevent the plug and socket from being unable to connect due to excessive deviation or being damaged due to excessive stress.

[0099] In the related art, the floating module for blind-plug connectors usually includes a base and a plug-in component disposed in the base, and the outer periphery of the plug-in component is connected to a plurality of springs, and the plug-in component is movably connected to the base through the springs. With such an arrangement, when the electronic device to be liquid-cooled is docked with the coolant supply device, the floating module will first contact the guide module, and the spring will be deformed under the force of the guide module, so that the plug-in component installed on the floating joint moves, thereby ensuring that the electronic device to be liquid-cooled and the plug-in component on the coolant supply device can be centrally aligned.

[0100] However, this floating module can only absorb deviations along the axial and radial directions of the blind-mate connector. When either the pin or the plug of the blind-mate connector is tilted, the floating module cannot absorb this docking deviation, which may easily cause the plug and the pin to be unable to be smoothly plugged in. Even if they are forced to be plugged in, it is easy to cause loose contact and damage the plug or the pin.

[0101] In addition, this floating module also requires elastic members to be arranged around the connector, resulting in a large number of elastic members required for the floating module, a more complex structure of the floating module, and a higher cost.

[0102] Thirdly, in order to ensure that the floating module has a large floating amount, it is necessary to ensure that the elastic members around the floating module have a large compression space, which results in a larger overall volume of the floating module.

[0103] Combine the following Figure 1 to Figure 2 , describing embodiment 1 of the present invention.

[0104] According to an embodiment of the present invention, on the one hand, a floating module is provided for a blind plug connector, comprising a main body 1, a first plug-in connector 2, a return slider 3 and an elastic member 5. A guide channel 101 is formed in the main body 1, and a first flange 102 and a second flange 103 are formed on the inner wall of the guide channel 101 and are arranged at intervals along the axial direction of the guide channel 101. The first plug-in connector 2 is at least partially arranged in the guide channel 101, and an annular protrusion 201 is formed on the outer periphery of the first plug-in connector 2, and the annular protrusion 201 is located between the first flange 102 and the second flange 103. The return slider 3 is movably arranged in the guide channel 101 and is arranged around the outside of the first plug-in connector 2, and the return slider 3 is against the side of the annular protrusion 201 close to the second flange 103, and a guide slope 4 is formed between the return slider 3 and the annular protrusion 201, and the guide slope 4 is inclined in the direction away from the axis of the guide channel 101 in the direction close to the first flange 102. The elastic member 5 is disposed in the guide channel 101 and supported between the return slider 3 and the second flange 103 .

[0105] During use of the floating module of the embodiment of the present invention, when the first connector 2 is connected to the corresponding second connector 6, there is an axial or radial deviation between the first connector 2 and the second connector 6, or when the first connector 2 and the second connector 6 are arranged at an angle, the first connector 2 of the floating module can contact the guide module, and the guide module can apply a force to the first connector 2, which can be transmitted to the return slider 3 through the annular protrusion 201, thereby pushing the return slider 3 to move backward, and at the same time, the first connector 2 moves in the direction of the force, thereby realizing the floating of the first connector 2, so as to ensure that the first connector 2 can be accurately connected to the corresponding second connector 6, and the angular deviation of the first connector 2 can be absorbed by the elastic member 5.

[0106] Since the guide slope 4 is configured to be inclined in the direction close to the first flange 102 toward the direction away from the axis of the guide channel 101, the first connector 2 can move axially along the guide channel 101 relative to the guide channel 101, move radially along the guide channel 101 relative to the guide channel 101, and can also be set at an angle to the axial direction of the guide channel 101.

[0107] By such a configuration, no matter whether the pin and the plug of the blind-mate connector deviate along the axial or radial direction of the blind-mate connector, or any of the plug and the pin of the blind-mate connection tilts, the floating module of the embodiment of the present application can absorb the error between the pin and the plug of the blind-mate connector, thereby ensuring that the pin and the plug of the blind-mate connector can be smoothly plugged into place without damaging the blind-mate connector.

[0108] In addition, the floating module of the embodiment of the present invention cooperates with the return slider 3 through an elastic member 5 to ensure that the first connector 2 has a large floating amount in multiple directions, thereby reducing the number of elastic members 5 required for the floating module, reducing the cost of the floating module, and making the structure of the floating module more compact, thereby reducing the space required for the floating module.

[0109] Therefore, the floating module of the embodiment of the present invention can overcome the problem in the related art that the floating module of the blind-plug connector cannot be applied to the working condition where any of the pins and plugs of the blind-plug connector are tilted, which easily causes the plug and the pin to be unable to dock smoothly, which easily causes loose contact and damage to the plug or the pin, and can reduce the number of elastic members 5 required for the floating module, reduce the cost of the floating module, and the floating module requires less space and has a compact structure. In addition, the floating module has a simple structure, is easy to assemble, is safe and reliable to use, and is easy to implement and promote.

[0110] The first connector 2 is used for plugging with the second connector 6 , one of which can be a blind-mate plug, and the other of which can be a blind-mate socket.

[0111] Furthermore, in some embodiments of the present application, the guiding slope 4 is arranged around the outer circumference of the first connector 2 , and the center line of the guiding slope 4 coincides with the axis of the guiding channel 101 .

[0112] By such an arrangement, 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 bevel 4, and the 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 be separated from the guide module, thereby losing the force applied by the guide module. At this time, the force in the radial direction of the guide channel 101 applied by the return slider 3 to the annular protrusion 201 can drive the first connector 2 to be centered in the guide sleeve 7.

[0113] Further, in some embodiments of the present application, the guide slope 4 includes a first annular surface and a second annular surface, wherein the first annular surface is arranged on the annular protrusion 201 and the second annular surface is arranged on the return slider 3, and the first annular surface and the second annular surface have the same inclination.

[0114] By such arrangement, it can be ensured that the annular protrusion 201 moves more smoothly relative to the return slider 3 .

[0115] It should be noted that the inclinations of the first annular surface and the second annular surface are consistent, which means that the angle formed by the first annular surface and the second annular surface is in the range of -1° to 1°.

[0116] As a changeable implementation, the first annular surface and the second annular surface may also be arranged at a certain angle.

[0117] As another alternative embodiment, the guiding inclined surface 4 only includes a first annular surface provided on the annular protrusion 201 , or the guiding inclined surface 4 only includes a second annular surface provided on the return slide 3 .

[0118] Further, in some embodiments of the present application, the first plug connector 2 includes a plug section 202 and a connecting section 203. The plug section 202 is disposed outside the main body 1 and is located on a side of the annular protrusion 201 away from the elastic member 5. The connecting section 203 is connected between the plug section 202 and the annular protrusion 201, the diameter of the plug section 202 is greater than the inner diameter of the first flange 102, and the diameter of the connecting section 203 is less than or equal to the inner diameter of the first flange 102.

[0119] By such an arrangement, when the first connector 2 has been plugged into place with the second connector 6, but the electronic device to be liquid-cooled has not yet been moved to a fixed position, the operator can continue to push the liquid-cooling device to move along the plugging 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 member 5, so that the error of the system in the axial direction is absorbed by the elastic member 5, ensuring that the electronic device can be smoothly installed in place without causing damage to the blind-plug connector.

[0120] In the description of the embodiments of the present application, it should be noted that the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" refers to two or more, unless otherwise clearly and specifically defined.

[0121] Among them, the return slider 3 can be selected as an integrated structure. As a convertible implementation method, the return slider 3 is spliced ​​by multiple guide plates, and the multiple guide petals are arranged in sequence 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.

[0122] Further, in some embodiments of the present application, the plug section 202 includes a plug connector 2021, a fixing sleeve 2022 and a first sealing ring 2023. The plug connector 2021 can be selected as one of a blind plug and a blind socket. Figure 5 In the illustrated embodiment, the plug connector 2021 is a blind plug. The fixing sleeve 2022 is sleeved on the outer circumference of the plug connector 2021, and the connecting section 203 includes a connecting pipe, which is connected to the fixing sleeve 2022. The first sealing ring 2023 is sleeved outside the plug connector 2021 and clamped between the plug connector 2021 and the fixing sleeve 2022.

[0123] Through such an arrangement, the blind plug, the fixing sleeve 2022 and the connecting pipe are connected in sequence and can be used to transmit the coolant. The first sealing ring 2023 can be used to improve the sealing between the plug connector 2021 and the fixing sleeve 2022 to prevent the coolant from leaking.

[0124] The connecting section 203 and the annular protrusion 201 may be an integrally formed structure or a split structure and connected to each other. For example, in some optional embodiments, the connecting section 203 may be bonded or threaded to the annular protrusion 201. The connecting pipe may be used to connect a hose constituting a coolant channel. For example, Figure 5 As shown, one end of the connecting pipe away from the first flange 102 extends out from the guide channel 101, and an anti-skid convex ring 2031 is formed on the outer periphery. The anti-skid convex ring 2031 can be interference fit with the pipeline of the liquid cooling system when the connecting pipe is plugged into the pipeline of the liquid cooling system, thereby increasing the friction between the pipelines and preventing the pipeline from slipping off. It can also absorb and disperse the force to a certain extent to avoid connection failure or damage due to local concentrated force. In addition, the anti-skid convex ring 2031 can also improve the sealing between the pipelines, avoid leakage of coolant, affect the cooling effect, and even contact with the lines in the server cabinet.

[0125] The number of the anti-skid protruding ring 2031 can be selected to be one or more. For example, Figure 1 and Figure 2 In the illustrated embodiment, there are three anti-slip convex rings 2031 , which are evenly distributed at the ends of the connecting pipes, which can provide sufficient sealing for the connection between the pipelines without increasing the manufacturing cost of the connecting pipes.

[0126] The coolant can be water, water-based, glycol-based, dielectric liquid or refrigerant. Water-based coolant has good heat transfer performance, but antifreeze such as ethylene glycol or propylene glycol needs to be added to adapt to low temperature environments. Diol-based coolant has good antifreeze performance, but the increased viscosity of the liquid will affect the power consumption of the pump. Dielectric liquid has low conductivity and will not cause short circuits in electronic equipment, but the cost is relatively high. Refrigerants usually have higher latent heat and lower pump power consumption, but decomposition reactions may occur at high temperatures.

[0127] Although in the embodiment of the present application, the blind connector 2021 is a fluid blind connector 2021 for transmitting coolant, in an embodiment not shown in the accompanying 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 reach.

[0128] The first sealing ring 2023 is preferably but not limited to being made of materials such as rubber or silicone.

[0129] Furthermore, in some embodiments of the present application, the elastic member 5 includes a spring disposed around the outside of the first connector 2; a first anti-slip groove 301 is formed on the return slider 3, and the first end of the spring is limited to the first anti-slip groove 301. A second anti-slip groove 1031 is formed on the second flange 103, and the second end of the spring is limited to the second anti-slip groove 1031.

[0130] The first anti-slip ring groove 301 and the second anti-slip ring groove 1031 can be used to limit the spring to 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 limit the expansion and contraction of the spring in a direction perpendicular to the compression direction together with the inner wall of the guide channel 101 to prevent the spring from bending.

[0131] As a convertible embodiment, the elastic member 5 includes a plurality of springs, which are arranged at intervals along the circumference of the first connector 2, and a plurality of spring limiting grooves are formed on the return slider 3 and the second flange 103, respectively, and the ends of the springs are arranged in the spring limiting grooves.

[0132] Further, in some embodiments of the present application, the main body 1 includes a base 104. The first flange 102 is disposed on the base 104, and the second flange 103 is detachably connected to an end of the base 104 away from the first flange 102.

[0133] With such an arrangement, during the assembly process, the base 104 and the second flange 103 can be separated from each other, so that the operator can place the first connector 2, the return slider 3 and the spring into the guide channel 101 in sequence, and then connect the second flange 103 to the base 104, thereby limiting the first connector 2, the return slider 3 and the spring in the guide channel 101.

[0134] Preferably, after being assembled in place, the spring is in a compressed state and can provide a stable thrust for the return slider 3 .

[0135] It should be noted that, in the embodiment of the present application, the specific shape of the base 104 is not limited. Figure 1 In the illustrated embodiment, the base 104 is a cylindrical structure.

[0136] As an alternative implementation, in some embodiments not shown in the drawings, the base 104 may also be a prismatic cylinder, such as a prism with a triangular, square, pentagonal or hexagonal cross section.

[0137] As an alternative implementation, in an embodiment not shown in the drawings, the second flange 103 is formed on the base 104 , and the first flange 102 is detachably connected to an end of the base 104 away from the second flange 103 .

[0138] The base 104 and the second flange 103 are preferably connected to each other by, but not limited to, clamping, riveting, threading or welding. Figure 1 In the illustrated embodiment, 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 .

[0139] It should be noted that, in the embodiment of the present application, the specific shapes of the first connecting edge and the second connecting edge are not limited. Figure 1 In the illustrated embodiment, both the first connecting edge and the second connecting edge are square edges. As a convertible implementation, the first connecting edge and the second connecting edge may also be annular edges or elliptical edges, etc. When the first connecting edge and the second connecting edge are annular edges, the first connecting holes may be evenly distributed along the circumference of the first connecting edge, and the second connecting holes may be evenly distributed along the circumference of the second connecting edge.

[0140] When the first connection edge and the second connection edge are elliptical edges, the first connection hole may be arranged on the long axis of the first connection edge and symmetrically distributed on both sides of the guide channel 101. The second connection hole may be arranged on the long axis of the second connection edge and symmetrically distributed on both sides of the guide channel 101.

[0141] Furthermore, in some embodiments of the present application, the inner diameter of the first flange 102 is smaller than the outer diameter of the return slider 3 .

[0142] By such an arrangement, it is possible to prevent the return slider 3 from slipping out of the guide channel 101 .

[0143] In one embodiment, the inner diameter of the first flange 102 is smaller than the outer diameter of the annular protrusion 201 .

[0144] According to an embodiment of the present invention, on the other hand, a blind-mating connector is provided, comprising a floating module and a second plug-in connector 6 , wherein the second plug-in connector 6 can be plugged with the first plug-in connector 2 .

[0145] Combine the following Figures 1 to 5 , describing embodiment 2 of the present invention.

[0146] The blind-plug connector of the second invention of the present invention includes or uses the floating module of the first aspect of the present invention, and thus has its beneficial effects, namely: the blind-plug connector of the embodiment of the present invention can overcome the problem in the related art that the floating module of the blind-plug connector cannot be applied to any of the pins and plugs of the blind-plug connector when they are tilted, which easily causes the plug and the pin to be unable to dock smoothly, which easily causes loose contact and damages to the plug or the pin, and can reduce the number of elastic members 5 required for the floating module, thereby reducing the cost of the blind-plug connector, and the space required for the blind-plug connector is small and the structure is compact. In addition, the floating module has a simple structure, is easy to assemble, is safe and reliable to use, and is easy to implement and promote.

[0147] Furthermore, in some embodiments of the present application, the blind-mate connector further comprises a guide sleeve 7. The second connector 6 is disposed in the guide sleeve 7, and a guide section 701 is disposed on the guide sleeve 7. The inner diameter of the guide section 701 gradually decreases in a direction approaching the second connector 6.

[0148] In the related art, the guide module of the blind-mate connector generally includes a plurality of guide pins arranged on the outer periphery of the second connector 6, and the floating module is correspondingly provided with positioning holes corresponding to the guide pins. When the floating module is connected to the guide module, the guide pins can be inserted into the positioning holes, so that the plug and the pins can be accurately connected.

[0149] However, two or more guide pins need to be provided, which increases the volume of the floating module and aggravates the space shortage of the electronic equipment.

[0150] The blind-plug connector of the embodiment of the present application includes a guide sleeve 7 and a second connector 6 arranged in the guide sleeve 7. When the first connector 2 is connected to the corresponding second connector 6, when the first connector 2 and the second connector 6 deviate in the axial and radial directions, and the first connector 2 and the second connector 6 are arranged at an angle, the first connector 2 of the floating module can contact the guide section 701 of the guide sleeve 7, and the guide section 701 can apply a force to the first connector 2, and the force can be transmitted to the return slider 3 through the annular protrusion 201, thereby pushing the return slider 3 to move backward, and at the same time, the first connector 2 moves in the direction of the force, thereby realizing the floating of the first connector 2, so that the first connector 2 can be accurately connected to the second connector 6.

[0151] Moreover, compared with the scheme in which the guide pin and the guide hole are matched, the structure is simpler and more compact, and helps to improve the space utilization.

[0152] Furthermore, in some embodiments of the present application, the guide sleeve 7 further includes a straight section 703. The straight section 703 is connected to a side of the guide section 701 close to the second connector 6, and the straight section 703 can be clearance-matched with the first connector 2.

[0153] With such a configuration, the inner diameter of the straight tube section 703 is slightly larger than the outer diameter of the first connector 2, thereby ensuring that the first connector 2 can be smoothly inserted into the straight tube section 703 and its movement in the straight tube section 703 is not hindered. Preferably, the first connector 2 is a blind-plug plug or a blind-plug socket, and the deviation between the inner diameter of the straight tube section 703 and the first connector 2 can be compensated by the floating amount of the first connector 2 itself.

[0154] As an alternative embodiment, the guide sleeve 7 may also be configured not to have the straight section 703 .

[0155] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0156] Furthermore, in some embodiments of the present application, the first connector 2 and the second connector 6 are used to transport cooling liquid, and a liquid storage tank 702 is also provided on the inner periphery of the guide sleeve 7, and the liquid storage tank 702 is connected to the connection point between the first connector 2 and the second connector 6.

[0157] With such an arrangement, if coolant leaks during the docking process of the blind-mate connector, the coolant can be stored in the liquid storage tank 702, thereby preventing the coolant from leaking and coming into contact with the internal circuits of the server, causing a short circuit, corrosion, performance degradation or even equipment damage to the internal circuits of the server, affecting the normal operation of the server, or causing data loss and service interruption.

[0158] In addition, the liquid storage tank 702 can also reduce the material required for the guide sleeve 7 and reduce the weight of the guide sleeve 7 itself.

[0159] As a convertible implementation mode, in an embodiment not shown in the accompanying drawings, along the direction in which the second connector 6 and the first connector 2 are plugged into each other, the groove wall on one side of the liquid storage tank 702 close to the guide section 701 is arranged to be inclined toward the axial direction of the second connector 6, which can facilitate the operator to tilt the guide sleeve 7, thereby draining the coolant stored in the liquid storage tank 702.

[0160] As another convertible embodiment, a liquid outlet nozzle is formed on the outer periphery of the guide sleeve 7 , the liquid outlet nozzle is connected to the liquid storage tank 702 , and a plug is provided on the liquid outlet nozzle, and the operator can unplug the plug and drain the coolant in the liquid storage tank 702 .

[0161] Furthermore, in some embodiments of the present application, the liquid storage tank 702 is an annular groove arranged along the circumference of the guide sleeve 7.

[0162] As a convertible embodiment, the liquid storage tank 702 may also be optionally arranged only below the connection between the first connector 2 and the second connector 6 .

[0163] Furthermore, in some embodiments of the present application, the blind-plug connector further comprises a second sealing ring. The second sealing ring is sleeved on the outer circumference of the first plug connector 2, and when the first plug connector 2 is plugged with the second plug connector 6, the second sealing ring is located on a side of the liquid storage tank 702 away from the floating module, and is sandwiched between the first plug connector 2 and the guide sleeve 7.

[0164] By such arrangement, 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 circuits of the server.

[0165] The second sealing ring is preferably but not limited to being made of materials such as rubber or silicone.

[0166] Furthermore, in some embodiments of the present application, the blind-plug connector further comprises a limiting ring groove. The limiting ring groove is arranged along the circumference of the first plug-in component 2, and the second sealing ring is limited in the limiting ring groove.

[0167] By such arrangement, the limiting ring groove can limit the second sealing ring on the second connector 6, thereby preventing the second sealing ring from slipping during the connection between the first connector 2 and the second connector 6, resulting in loss of sealing effect.

[0168] As an alternative embodiment, the second sealing ring is bonded to the outer circumference of the second plug-in connector 6 .

[0169] As another convertible implementation, a limiting ring groove is formed on the inner periphery of the guide sleeve 7, and the second sealing ring is limited in the limiting ring groove.

[0170] As another alternative embodiment, the second sealing ring is bonded to the inner circumference of the guide sleeve 7 .

[0171] Furthermore, in some embodiments of the present application, the blind-mate connector further comprises a fixing column 8 . The second connector 6 is connected to the inner periphery of the fixing column 8 , and the guide sleeve 7 is connected to the outer periphery of the fixing column 8 .

[0172] By connecting the guide sleeve 7 and the second connector 6 simultaneously through a fixing column 8 , the structure of the blind-plug connector can be made simpler and more compact, and it helps to improve the coaxiality of the second connector 6 and the guide sleeve 7 .

[0173] Furthermore, in some embodiments of the present application, a first external thread is provided on the outer circumference of the fixing column 8, and a first internal thread is provided on the inner circumference of the guide sleeve 7, and the first external thread can be threadedly connected with the first internal thread.

[0174] A second internal thread is provided on the inner circumference of the fixing column 8 , and a second external thread is provided on the outer circumference of the second plug-in component 6 . The second internal thread can be threadedly connected with the second external thread.

[0175] It should be noted that in the embodiment of the present application, the specific shape of the guide sleeve 7 is not limited. Figure 3 In the illustrated embodiment, the guide sleeve 7 is a cylinder.

[0176] As an alternative implementation, in some embodiments not shown in the drawings, the guide sleeve 7 can also be selected as a prismatic cylinder, such as a prism with a triangular, square, pentagonal or hexagonal cross section.

[0177] When the guide sleeve 7 is a prismatic cylinder, the outer surface of the prismatic cylinder can be used as a rotation stop surface, which is convenient for the operator to thread the guide sleeve 7 with the fixing column 8. Preferably, the arc transition between two adjacent sides of the prismatic cylinder can avoid damaging the operator's hands.

[0178] As a convertible embodiment, the fixing column 8 can also be connected to the guide sleeve 7 and the second connector 6 by welding, clamping or bolting.

[0179] Furthermore, in some embodiments of the present application, a first anti-rotation surface 801 is provided on the outer periphery of the fixing column 8 , and a second anti-rotation surface 601 is provided on the outer periphery of the second connector 6 .

[0180] Through such an arrangement, when the fixing column 8 needs to be connected to the second connector 6, the operator can put the fixing column 8 on the second connector 6, and respectively pinch the first stop surface 801 and the second stop surface 601 with both hands to drive the first stop surface 801 and the second stop surface 601 to move in opposite directions, thereby threading the fixing column 8 and the second connector 6.

[0181] For example, in Figure 3 In the illustrated embodiment, a first hexagonal nut is formed on the fixing column 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.

[0182] As a convertible embodiment, the first anti-rotation surface 801 and the second anti-rotation surface 601 can also be selected as frosted surfaces.

[0183] Further, in some embodiments of the present application, the first connector 2 includes one of a blind-mate plug and a blind-mate socket, and the second connector 6 includes the other of a blind-mate plug and a blind-mate socket.

[0184] When the first connector 2 and the second connector 6 are a blind-mate plug and a blind-mate socket respectively, they themselves have a certain amount of floating, and can absorb a part of the system error through their own floating, thereby improving the reliability of the blind-mate connector.

[0185] According to an embodiment of the present invention, on the other hand, a liquid cooling system is provided, comprising an electronic device to be liquid cooled, a cooling liquid supply device, and a blind-mate connector according to the second aspect of the present invention. The floating module of the blind-mate connector is arranged on one of the electronic device to be liquid cooled and the cooling liquid supply device, and the second connector 6 of the blind-mate connector is arranged on the other of the electronic device to be liquid cooled and the cooling liquid supply device.

[0186] The electronic devices to be liquid-cooled are preferably but not limited to servers, server cabinets, storage devices, computers or batteries. Coolant supply equipment refers to devices used to provide and circulate coolant, usually including cooling towers, coolers, water pumps, expansion tanks, piping systems and other components. The coolant supply equipment can supply coolant to the electronic devices to be liquid-cooled through blind-plug connectors, and transfer and disperse the heat generated during the operation of the equipment to maintain the normal operating temperature of the equipment and prevent damage caused by overheating.

[0187] When the electronic device to be liquid-cooled is a server cabinet, the first connector 2 may be optionally arranged on a cooling medium supply and return manifold of the server cabinet.

[0188] In addition, the liquid cooling system of the embodiment of the present invention includes or uses the blind-plug connector of the second aspect of the present invention, and thus has its beneficial effect, namely, it can overcome the problem in the related art that the floating module of the blind-plug connector cannot be applied to the working condition where any of the pins and plugs of the blind-plug connector are tilted, which easily causes the plug and the pin to be unable to dock smoothly, easily causes loose contact, and damages the plug or the pin, and so on. Therefore, the connection between the electronic device to be liquid-cooled and the cooling liquid supply equipment is more reliable and smooth.

[0189] Since the blind-plug connector of the liquid cooling system of the embodiment of the present application is compact and low-cost, it can avoid aggravating the space shortage around the electronic device due to the blind-plug connector. In addition, the liquid cooling system has a simple structure, is easy to assemble, and is safe and reliable to use, which is convenient for implementation and promotion.

Any technician in the field can easily make changes or variations within the technical scope disclosed in the present invention, and such changes or variations should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
