Description

Blind plug connector and liquid cooling device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 5, 2022, with application number 202222067941.X and invention name “A blind plug connector and liquid cooling device”. The entire contents of the patent application are incorporated into this application by reference. Technical Field

[0002] The present application relates to the technical field of electronic equipment, and in particular to a blind plug connector and a liquid cooling device. Background Art

[0003] With the advent of the artificial intelligence era, chip power consumption is increasing rapidly as chip capabilities improve. This places higher demands on chip heat dissipation. Liquid cooling technology, due to its superior heat dissipation performance, is increasingly being used as a key method for chip heat dissipation. However, for larger servers and storage systems, external liquid cooling frames are often required to achieve liquid cooling.

[0004] Specifically, the aforementioned servers and storage devices are typically installed within a cabinet. Connecting the liquid cooling frame to the cabinet requires connectors. Commonly used connectors in the prior art are hand-insert connectors and blind-insert connectors. Hand-insert connectors require numerous connections and pipes, making maintenance relatively complex. Due to the large cumulative tolerances between cabinet-level connections, directly plugging blind-insert connectors into each other can result in poor assembly, necessitating the design of floating blind-insert connectors. Existing blind-insert connector solutions often have numerous parts and are complex to assemble.

[0005] Summary of the Invention

[0006] The present application provides a blind-plug connector and a liquid cooling device, which enable the blind-plug connector to be installed in a floating manner, and the structure of the blind-plug connector is relatively simple.

[0007] In a first aspect, the present application provides a blind-mate connector for plugging into a device to be cooled. The blind-mate connector comprises a floating bracket, a connector, and a floating assembly. The connector includes a plug end specifically configured to plug into the device to be cooled, thereby connecting the liquid cooling device to the structure to be cooled. The connector is slidably mounted on the floating bracket, with the sliding direction of the connector coinciding with the insertion direction of the connector. Thus, the blind-mate connector in this embodiment can float in the insertion direction to accommodate tolerances of the device to be cooled along the insertion direction, as well as tolerances between the blind-mate connector and the device to be cooled. The floating bracket is mounted to a fixed plate via the floating assembly. The floating assembly includes a protrusion and a floating hole. The floating hole has a larger diameter than the protrusion. The protrusion is mounted within the floating hole and is capable of circumferential movement within the floating hole. In this embodiment, the floating bracket can float circumferentially relative to the fixed plate. That is, the floating bracket can float relative to the fixed plate in a plane perpendicular to the insertion direction, thereby accommodating tolerances of the device to be cooled along the plane perpendicular to the insertion direction, as well as tolerances between the blind-mate connector and the device to be cooled. Specifically, the protrusion can be located on the fixed plate and the floating hole can be located on the floating bracket, or the protrusion can be located on the floating bracket and the floating hole can be located on the fixed plate. The blind plug connector in this solution can float in all directions and has a relatively simple structure.

[0008] The blind-mate connector may also include an elastic member installed between the connector and the floating bracket to apply a restoring force to the plug end in the direction of insertion toward the device to be cooled. This elastic member ensures a reliable connection between the plug end of the connector and the device to be cooled, reducing the risk of leakage.

[0009] The floating assembly may further include a screw, wherein the thickness of the floating hole is smaller than that of the protrusion, the protrusion has a screw hole, and the screw is installed in the screw hole so that the protrusion is located in the floating hole. The screw installation method is easy to install and remove, and has a simple structure and is easy to prepare.

[0010] The blind-mate connector also includes an auxiliary plate. When the protrusion is located on the floating bracket and the floating hole is located on the fixed plate, the auxiliary plate is located on the side of the fixed plate facing away from the floating bracket. The auxiliary plate includes a first mounting hole, through which a screw passes to securely connect the auxiliary plate and the floating bracket. In this technical solution, the fixed plate is located between the auxiliary plate and the floating bracket, which helps improve the structural reliability of the floating bracket installation.

[0011] In another technical solution, when the blind-mate connector includes an auxiliary plate, the floating bracket can also include a connecting plate, with the floating hole located in the connecting plate and the protrusion located in the fixed plate. The auxiliary plate is located on the side of the connecting plate facing away from the fixed plate and includes a second mounting hole through which screws pass to securely connect the auxiliary plate and the fixed plate. In this technical solution, the connecting plate of the floating bracket is located between the auxiliary plate and the fixed plate, which also improves the structural reliability of the floating bracket installation.

[0012] To accommodate the aforementioned connector, the floating bracket also includes a housing cavity, with the connector at least partially located within it. The cavity comprises a bottom wall and side walls, with the elastic member mounted between the bottom wall and the connector end. In this solution, the housing cavity protects the connector end and accommodates accessories such as the elastic member, enhancing the convenience of blind-mate connector installation and use.

[0013] In a further technical solution, the sidewall includes a stop step, and the connector has a first surface that engages with the stop step. When the connector moves toward the bottom wall a first predetermined distance, the first surface abuts the step. This first predetermined distance determines the floating distance of the blind-mate connector along the insertion direction.

[0014] The opening of the accommodating cavity is detachably provided with a stopper, and the connector has a second table surface that cooperates with the stopper and abuts against the stopper. The stopper can reliably accommodate part of the connector structure in the accommodating cavity without falling off, and the structure is relatively simple.

[0015] In an alternative technical solution, the diameter of the floating hole differs from the diameter of the protrusion by 5 mm or less. This allows the blind-mate connector to float circumferentially no more than 5 mm, meeting tolerance requirements. However, if the diameter of the floating hole differs significantly from the diameter of the protrusion, alignment of the blind-mate connector with the heat dissipation device becomes difficult, making operation more challenging.

[0016] Furthermore, the sliding travel of the connector relative to the floating bracket is 5 mm or less. This means the floating distance of the blind-mate connector along the insertion direction does not exceed 5 mm, meeting tolerance requirements. Furthermore, if the sliding travel is too large, it will be difficult to ensure a reliable connection between the connector and the device being cooled, which can easily lead to leakage.

[0017] In order to improve the connection efficiency of the blind-mate connector, the blind-mate connector includes at least two connectors, so that one plugging operation can achieve the connection of at least two connectors.

[0018] In a second aspect, the present application further provides a liquid cooling device comprising the blind-plug connector of the first aspect, further comprising a liquid storage chamber and a pipe. One end of the pipe is connected to the liquid storage chamber, and the other end is connected to the blind-plug connector, thereby achieving communication between the blind-plug connector and the liquid storage chamber.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0027] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and appended claims of this application, the singular expressions "a", "an", "said", "above", "the", and "this" are intended to also include expressions such as "one or more", unless the context clearly indicates otherwise.

[0028] References in this specification to "one embodiment" or "a specific embodiment" mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. The terms "including," "comprising," "having," and their variations all mean "including but not limited to," unless otherwise specifically stated.

[0029] In order to facilitate understanding of the blind plug connector and liquid cooling device provided in the embodiment of the present application, the following first introduces its application scenario. Liquid cooling technology is a commonly used heat dissipation method with good heat dissipation capacity. For cabinet-level electronic equipment such as servers and storage devices arranged in a cabinet, an external liquid cooling device is usually used to dissipate heat from the electronic devices to ensure the heat dissipation capacity of the electronic devices and improve the service life of the electronic devices. In a specific embodiment, the above-mentioned liquid cooling device can also be referred to as a liquid cooling frame or a liquid cooling system. It is necessary to be able to transmit refrigerant between the liquid cooling device and the cabinet, so a connector can be used to connect the liquid flow port of the liquid cooling device to the liquid flow port of the cabinet. In order to simplify the operation, a blind plug connector can be used to achieve the above connection. Since the cumulative tolerance of the connection between the cabinet where the equipment is placed and the liquid cooling cabinet is relatively large, the direct insertion of the blind plug connector will result in poor connector assembly, so it is necessary to design a floating blind plug connector. The existing blind plug connector solutions have many parts and are complicated to assemble.

[0030] FIG1 is a schematic structural diagram of a blind-mate connector provided in the present application. FIG1 illustrates a cross-sectional structure of a blind-mate connector 100. As shown in FIG1 , the blind-mate connector 100 in the embodiment of the present application includes a floating bracket 1, a connector 2, and a floating assembly 5. The floating bracket 1 serves as a bracket for the blind-mate connector 100, and the connector 2 floats relative to the floating bracket 1, thereby forming a floating blind-mate connector 100. The connector 2 includes a plug-in end 21 for connecting to a device to be cooled, which may specifically be a server cabinet, a storage cabinet, an electronic device within a cabinet, or a component of an electronic device. The connector 2 is slidably assembled to the floating bracket 1, and the sliding direction of the connector 2 coincides with the insertion direction of the connector 2. In other words, the connector 2 is slidably assembled to the floating bracket 1 along the insertion direction. When the blind-mate connector 100 is plugged into the device to be cooled, if the connection is not accurate, the plug-in end 21 of the connector 2 can be pushed away from the device to be cooled. This allows the blind-mate connector 100 to float along the insertion direction.

[0031] The blind-mate connector 100 may also include an elastic member 3, which is installed between the connector 2 and the floating bracket 1 and applies a restoring force to the plug end 21 in the insertion direction toward the device to be cooled. Therefore, when the blind-mate connector 100 is plugged into the device to be cooled, the elastic member 3 can press the connector 2 against the device to be cooled, ensuring a reliable connection between the plug end 21 and the device to be cooled.

[0032] Continuing with Figure 1 , the floating bracket 1 includes a housing 11, with the connector 2 at least partially located within it. The housing 11 includes a bottom wall 111 and side walls 112, with the elastic member 3 mounted between the bottom wall 111 and the plug end 21. In this embodiment, the plug end 21 of the connector 2 can slide within the housing 11 along the insertion direction. The housing 11 in this embodiment also protects the plug end 21 and accommodates accessories such as the elastic member 3, enhancing the convenience of installation and use of the blind-mate connector 100.

[0033] In a specific embodiment, the elastic member 3 is installed between the bottom wall 111 and the plug-in end 21, which means that the elastic member 3 is located on the side of the plug-in end 21 facing the bottom wall 111. When the elastic member 3 is installed, one end of the elastic member 3 can be connected to the plug-in end 21 of the connector 2, and the other end can be connected to the bottom wall 111 of the accommodating cavity 11. Alternatively, in another embodiment, one end of the elastic member 3 can be connected to the plug-in end 21 of the connector 2, and the other end can be connected to the side wall 112 of the accommodating cavity 11. In other words, as long as the elastic member 3 is located on the side of the plug-in end 21 facing the bottom wall 111, it will suffice. The elastic member 3 can specifically be a linear spring with a simple structure and low cost.

[0034] Please continue to refer to Figure 1. The side wall 112 may also include a limiting step 1121, and the connector 2 has a first table 22 that cooperates with the limiting step 1121. When the blind-plug connector 100 is not in use, the limiting step 1121 and the first table 22 are spaced apart by a first preset distance along the insertion direction. Then, when the connector 2 moves the first preset distance toward the bottom wall 111, the first table 22 abuts against the step. This solution can limit the plug-in end 21 to prevent the plug-in end 21 from being retracted too much into the accommodating cavity 11. The first preset distance can be specifically determined based on the installation tolerance of the device to be cooled along the above-mentioned insertion direction, and the installation tolerance of the blind-plug connector along the above-mentioned insertion direction. It can be considered that the first preset distance determines the floating distance of the blind-plug connector along the insertion direction.

[0035] Furthermore, to ensure the connector 2's plug-in portion is securely positioned within the accommodating cavity 11 of the floating bracket 1, a removable stopper 12 is installed at the opening of the accommodating cavity 11. The connector 2 has a second surface 23 that mates with the stopper 12, and the second surface 23 and the stopper 12 can abut against each other. In this solution, the stopper 12 can limit the position of the connector 21 on the other side, ensuring its secure placement within the floating bracket 1.

[0036] In a specific embodiment, the sliding stroke of the connector 2 relative to the floating bracket 1 can be determined based on the installation tolerance of the device to be cooled along the above-mentioned insertion direction, and the installation tolerance of the blind-plug connector along the above-mentioned insertion direction. Specifically, the sliding stroke of the connector 2 relative to the floating bracket 1 can be less than or equal to 5mm. Specifically, the above-mentioned first preset distance can be less than or equal to 5mm, or the distance between the above-mentioned limiting step 1121 and the stopper 12 can be less than or equal to 5mm. For example, the sliding stroke of the above-mentioned connector 2 relative to the floating bracket 1 can be 0.5mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.5mm, 3mm, 3.3mm, 3.5mm, 3.7mm, 4mm, 4.5mm or 4.9mm, etc. The present application does not impose any restrictions on the specific value of the above-mentioned sliding stroke. If the above-mentioned sliding stroke is less than or equal to 5mm, the blind-plug requirement can be met. If the sliding stroke is too large, it is difficult to ensure the reliability of the connection between the connector and the device to be cooled, which can easily cause leakage.

[0037] FIG2 is an exploded view of a blind-mate connector according to an embodiment of the present application. As shown in FIG2 , the blind-mate connector 100 further includes a fixing plate 4, which is mounted to the base, thereby securing the entire blind-mate connector 100 to the base. The floating bracket 1 is mounted to the fixing plate 4 via a floating assembly 5. Specifically, the floating assembly 5 includes a protrusion 52 and a floating hole 51. The floating hole 51 has a larger diameter than the protrusion 52. When the protrusion 52 is inserted into the floating hole 51 and assembled within the floating hole 51, the protrusion 52 can move circumferentially within the floating hole 51, allowing the protrusion 52 to float circumferentially relative to the floating hole 51. In a specific embodiment, the protrusion 52 is located on the fixing plate 4, and the floating hole 51 is located on the floating bracket 1. This allows the floating bracket 1 to float circumferentially with respect to the fixing plate 4. Alternatively, in another embodiment, the protrusion 52 can be located on the floating bracket 1, and the floating hole 51 can be located on the fixing plate 4. This also allows the floating bracket 1 to float circumferentially with respect to the fixing plate 4. When the blind-plug connector 100 is plugged into the device to be cooled, if the circumferential docking is inaccurate, the connector 2 can be shaken within a certain range along the circumferential direction to ensure that the plug-in end 21 is reliably connected to the device to be cooled. Therefore, the floating of the blind-plug connector 100 along the circumferential direction can be achieved. Therefore, the blind-plug connector 100 in the embodiment of the present application can achieve all-round floating in the axial and circumferential directions, thereby simplifying the plug-in process. In addition, the structure of the blind-plug connector 100 in the embodiment of the present application is relatively simple, and the assembly process is also relatively simple. For example, the blind-plug connector in the embodiment shown in Figure 2, in addition to the connector, includes 14 spare parts, including four structural parts, 8 fasteners (screws) and 2 springs (reset parts).

[0038] Figure 3 is a schematic diagram of a partial structure of a blind-mate connector according to an embodiment of the present application, and Figure 4 is a schematic diagram of a structure of a blind-mate connector according to an embodiment of the present application. As shown in Figures 3 and 4 , in a specific embodiment, the floating assembly 5 may further include a screw 53. The thickness of the floating hole 51 is smaller than the thickness of the protrusion 52. Specifically, the thickness may be the dimension of the protrusion 52 in the extension direction, or in other words, the dimension along the insertion direction of the blind-mate connector 100. After the protrusion 52 is inserted into the floating hole 51, it can protrude a certain distance from the other end of the floating hole 51. The protrusion 52 has a screw hole 53. The screw 53 is installed in the screw hole 53, thereby securing the protrusion 52 within the floating hole 51 and preventing it from falling out. In other words, the protrusion 52 is axially fixed to the floating hole 51. Of course, to ensure that the protrusion 52 can circumferentially move relative to the floating hole 51, the protrusion 52 and the floating hole 51 can be arranged to be non-closely aligned axially to avoid excessive friction that would otherwise prevent the protrusion 52 from moving relative to the floating hole 51.

[0039] Figure 5 is a schematic diagram of the lateral structure of the blind-plug connector in an embodiment of the present application. Please refer to Figures 2, 4 and 5. In one embodiment, the blind-plug connector 100 further includes an auxiliary plate 6. The protrusion 52 is located on the floating bracket 1, and the floating hole 51 is located on the fixed plate 4. The auxiliary plate 6 is located on the side of the fixed plate 4 away from the floating bracket 1. The auxiliary plate 6 includes a first mounting hole, and the screw 53 passes through the first mounting hole to fix the auxiliary plate 6 and the floating bracket 1. In this solution, the auxiliary plate 6 is fixed to the floating bracket 1, and the fixed plate 4 is located between the auxiliary plate 6 and the floating bracket 1. The auxiliary plate 6 and the floating bracket 1 simultaneously swing circumferentially relative to the fixed plate 4, which is beneficial to improving the reliability of the circumferential floating of the floating bracket 1, and makes the fixed connection of the floating bracket 1 to the fixed plate 4 in the axial direction more reliable.

[0040] Please continue to refer to FIG. 5 . In a specific embodiment, the auxiliary plate 6 and the fixed plate 4 are fixedly connected with a gap, so that the floating bracket 1 can float circumferentially relative to the fixed plate.

[0041] When the above-mentioned fixing plate is specifically set, the above-mentioned fixing plate may include a first plate 61 and a second plate 62, and the above-mentioned first plate 61 and second plate 62 may be specifically set vertically. Here, the vertical setting of the first plate 61 and second plate 62 means that the above-mentioned first plate 61 and second plate 62 are approximately perpendicular to each other. For example, the angle between the first plate 61 and second plate 62 can be 88° to 92°. For example, the angle between the above-mentioned first plate 61 and second plate 62 can be 89°, 89.5°, 90°, 90.5° or 91°, etc. Among them, the first plate 61 is used to install the floating bracket 1, and the second plate 62 is used to be installed on the base. This solution installs the blind plug connector 100 to the base at the edge.

[0042] In another embodiment, when the protrusion 52 is located on the fixed plate and the floating hole 51 is located on the floating bracket 1, the floating bracket 1 can include a connecting plate, and the floating hole 51 is located on the connecting plate. The auxiliary plate 6 is located on the side of the connecting plate away from the fixed plate. The auxiliary plate 6 includes a second mounting hole, and the screw 53 passes through the second mounting hole to fix the auxiliary plate 6 and the fixed plate. In this embodiment, the auxiliary plate 6 and the fixed plate are relatively fixed and will not move with the floating bracket 1. The connecting plate of the floating bracket 1 is located between the auxiliary plate 6 and the fixed plate, which can also improve the reliability of the floating bracket 1 floating in the circumferential direction and make the fixed connection between the floating bracket 1 and the fixed plate in the axial direction more reliable.

[0043] In a specific embodiment, the diameters of the floating hole 51 and the protrusion 52 can be determined based on the circumferential installation tolerance of the device to be cooled along the insertion direction, as well as the circumferential installation tolerance of the blind-mate connector along the insertion direction. Specifically, the difference between the diameters of the floating hole 51 and the protrusion 52 is less than or equal to 5 mm. In other words, the circumferential floating distance between the floating bracket 1 and the fixed plate is less than or equal to 5 mm. This application does not limit the specific value of the sliding stroke. For example, the sliding stroke of the connector 2 relative to the floating bracket 1 can be 0.5 mm, 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 2.5 mm, 3 mm, 3.3 mm, 3.5 mm, 3.7 mm, 4 mm, 4.5 mm, or 4.9 mm. The circumferential floating distance of the blind-mate connector does not exceed 5 mm, thus meeting the tolerance requirements. Furthermore, if the diameters of the floating hole 51 and the protrusion 52 differ significantly, it will be difficult to align the blind-mate connector with the device to be cooled, making operation more difficult.

[0044] In a specific embodiment, the blind-mate connector 100 includes at least two connectors 2 , thereby improving the integration of the blind-mate connector 100 and facilitating improving the connection efficiency of the blind-mate connector 100 .

[0045] FIG6 is a structural schematic diagram of a liquid cooling device in an embodiment of the present application. As shown in FIG6 , based on the same concept, the present application also provides a liquid cooling device, which includes the blind plug connector 100 in the above embodiment, and may also include a liquid storage chamber 200 and a pipe 300. The above liquid storage chamber 200 can be filled with refrigerant, and one end of the above pipe 300 is connected to the liquid storage chamber 200, and the other end is connected to the blind plug connector 100, so that the refrigerant in the liquid storage chamber 200 can flow to the device to be cooled through the pipe 300 and the blind plug connector 100. The blind plug connector 100 in the embodiment of the present application is a floating connector, which is convenient for plugging the blind plug connector 100 into the device to be cooled; the structure of the above blind plug connector 100 is relatively simple and the cost is low.

[0046] Specifically, the liquid storage chamber 200 may be a liquid storage chamber of a liquid cooling radiator, or a liquid storage chamber of a heat exchanger, etc., and this application does not impose any limitation thereto.

[0047] As a possible implementation method, the present application also provides a system, which includes a cabinet for placing electronic equipment and a liquid cooling device. The liquid cooling device is used to dissipate heat from the electronic equipment or specified components in the electronic equipment. The structure of the liquid cooling device can be referred to the liquid cooling device shown in Figure 6 above. For the sake of brevity, it will not be repeated here.

[0048] As a possible implementation method, the liquid cooling device provided in this application belongs to a different cabinet from the cabinet where the electronic equipment is placed. The above-mentioned blind plug connector is also applicable to the scenario where the liquid cooling device and the electronic equipment are in the same cabinet. The structure of the blind plug connector is similar to the structure shown in Figures 1 to 5. For the sake of brevity, it will not be repeated here.

[0049] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
