Description

Technical Field

[0001] This application relates to the field of server technology, and more particularly to a server. Background Technology

[0002] In liquid-cooled server systems, blind-fit connectors are widely used due to their ease of maintenance.

[0003] In related technologies, blind-mating joints utilize an axial spring and a beveled structure to achieve axial and radial floating. However, this type of joint is prone to jamming during mating, which not only reduces the reliability of blind-mating operations but may also damage the joint's lifespan due to long-term misalignment. Summary of the Invention

[0004] This application provides a server that can improve the reliability of blind insertion operations between the first connector and the second connector on the rack.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions: This application provides a server, including: The chassis contains heat dissipation devices. The first connector is used to connect to the second connector of the cabinet. The first connector includes: The connector body has a receiving cavity and a first end and a second end. The first end is used to connect with the second connector, and the second end is connected with the heat dissipation device so that the coolant flows through the receiving cavity into the heat dissipation device. Mounting bracket, connected to the connector body and connected to the chassis; The first alignment block is sleeved on the first part of the connector body and has a first gap between it and the first part of the connector body along the radial direction of the connector body. The first gap is used to allow the connector body to move radially during the insertion of the first connector and the second connector. The axial elastic element is disposed between the mounting base and the first alignment block and is used to provide the first alignment block with a first elastic force along the axial direction of the connector body so that the first alignment block moves axially during the insertion of the first connector and the second connector.

[0006] According to an embodiment of this application, a server is provided: on one hand, a first alignment block is sleeved on a first part of the connector body, and an axial elastic element is disposed between the mounting base and the first alignment block; when the first connector is subjected to an axial force from the second connector, the axial force is transmitted to the axial elastic element through the first alignment block. The axial elastic element, through its own compression deformation, allows the first alignment block and the connector body to move together axially to absorb axial mating tolerances. On the other hand, a first gap is configured in the radial gap between the first alignment block and the connector body. When the first connector and the second connector are mated, the connector body can float radially relative to the first alignment block within the range determined by the first gap to achieve radial mating with the pipeline, i.e., absorb radial mating tolerances. It can be seen that this design achieves structural decoupling of the radial and axial floating functions of the connector body by placing the axial elastic element between the mounting base and the first alignment block, and by setting a first gap between the first alignment block and the connector body. In other words, axial and radial floating occur between different mating surfaces of the first connector, and the forces required for floating are provided by different components. This makes the radial and axial floating of the connector body independent and non-interfering, improving the floating effect and enhancing the reliability and convenience of blind mating operations between the first and second connectors. Simultaneously, the axial floating of the first connector no longer needs to overcome the frictional resistance of the radial floating surface, thus reducing the compressive force required by the axial elastic element. Furthermore, the radial floating is no longer affected by the component of the first elastic force, making the floating more sensitive. These factors collectively improve the overall floating effect of the first connector. Moreover, because the radial and axial floating of the connector body are independent, the first connector's adaptability to dimensional tolerances is improved, enabling it to be compatible with multiple second connector designs with different axial and radial tolerances, thus enhancing the server's versatility.

[0007] In some embodiments, the first connector further includes a guide member axially connected between the mounting base and the first alignment block; an axial elastic member is sleeved on the guide member.

[0008] In the embodiments of this application, the guide member can provide guidance for the deformation process of the axial elastic member, effectively preventing the axial elastic member from deflecting or becoming unstable during the deformation process, and improving the reliability of the joint body to move axially under the action of the axial elastic member.

[0009] In some embodiments, the first connector further includes an elastic reset member, which is sleeved on the first portion and located between the first portion and the first alignment block; the elastic reset member provides a second elastic force in the radial direction to the connector body, the second elastic force being used to maintain or restore the first central axis of the connector body to coincide with the second central axis of the first alignment block.

[0010] In this embodiment, by introducing an elastic reset member, while ensuring that the first gap provides the radial floating function of the first connector, the ability of the connector body to automatically reset radially to the first central axis and the second central axis to coincide is realized. This ensures that the connector body can be stably in the centering state, making it easy to re-insert with the second connector, and improving the reliability of the long-term permissible insertion of the first connector and the second connector in blind insertion operation.

[0011] In some embodiments, the first connector further includes a first stop portion and a second stop portion, which are axially spaced apart on the outer side of the connector body; the two ends of the elastic reset member abut against the first stop portion and the second stop portion respectively along the axial direction.

[0012] In this embodiment, a first stop and a second stop are axially spaced on the connector body and positioned axially on its outer side. This constrains the two ends of the elastic reset member, which is fitted onto the connector body, along its own axial direction, and they abut against the first and second stops respectively. Thus, the first and second stops provide a clear and fixed axial bearing surface for the elastic reset member, ensuring stable axial compression. The elastic reset member is confined between the first and second stops, preventing wear or instability during long-term use. This improves the reliability of the continuous allowable connection between the first and second connectors of the floating connector during blind insertion operations. Specifically, after repeated blind insertion operations, the first connector maintains consistent reset accuracy and reliable connection performance to meet long-term operational stability requirements.

[0013] In some embodiments, the inner wall of the first alignment block has an outwardly protruding portion; The elastic reset element includes: The first pagoda spring abuts against the first stop and the protrusion at both ends along the axial direction of the connector body; The second pagoda spring abuts against the protrusion and the second stop at both ends along the axial direction of the connector body.

[0014] In this embodiment, a protrusion is provided on the inner wall of the first alignment block, and the elastic reset member is configured as a first pagoda spring and a second pagoda spring located on both sides of the protrusion, forming a series of elastic supports. When the connector body is radially offset relative to the first alignment block, the pagoda spring on the offset side is compressed, while the pagoda spring on the opposite side of the offset is stretched or maintains support. The protrusion, as the intermediate force transmission and guiding member, effectively couples the forces of the two springs, which act together on the connector body, providing a restoring force pointing towards the radial center of the connector body. Thus, by utilizing the characteristics of the pagoda spring, the radial support stiffness is enhanced, improving the centering reset accuracy and docking reliability of blind mating.

[0015] In some embodiments, the first pagoda spring and the second pagoda spring are symmetrically arranged based on the protrusion.

[0016] In this embodiment, the symmetrical design ensures that when the connector body undergoes radial displacement, the force arms of the two pagoda springs on both sides of the protrusion are symmetrical with the force conditions. This results in the second elastic force generated by the two pagoda springs being equal in magnitude, opposite in direction, and radially pointing towards the radial center of the connector body. Accordingly, the symmetrical arrangement prevents uneven wear, jamming, or unilateral wear that may be caused by uneven force on the pagoda springs, and improves the connector body's ability to automatically return to the first and second central axes. This ensures that the connector body can be stably aligned, facilitating re-interlocking with the second connector and improving the reliability of the long-term permissible interlocking between the first and second connectors during blind interlocking operations.

[0017] In some embodiments, the first connector further includes: The second alignment block is fitted onto the second part of the connector body and is fixedly connected to the second part of the connector body.

[0018] The guide sleeve, which passes through the second alignment block along the axial direction, is used to mate with the guide pin of the second connector.

[0019] In this embodiment, by fixing the second alignment block to the connector body, the second alignment block and the connector body are combined into an integral floating unit. When there is a radial deviation between the first and second connectors, the radial force acting on the connector body will be directly transmitted to the second alignment block, enabling the integral floating unit to move radially in a coordinated manner under the constraint of the first gap. This improves the force distribution during radial movement, and the greater contact and guiding area between the second and first alignment blocks enhances the stability and structural integrity of the radial movement process.

[0020] In some embodiments, the first connector further includes: An elastic block is elastically connected to either the first or second alignment block. The centering pin is connected to the first alignment block and the second alignment block in a direction parallel to the axial direction of the connector body, and the centering pin is partially inserted into the elastic block.

[0021] In this embodiment, radial rotation between the first and second alignment blocks is achieved by introducing an elastic block and a centering pin. The second alignment block is axially connected to the first alignment block via the centering pin, with the centering pin partially inserted into the elastic block. When there is a rotational deviation between the second and first connectors—that is, an angular difference between the actual and theoretical positions of the two guide pins relative to the radial center of the second alignment block—the second alignment block can adaptively rotate along its own axis relative to the first alignment block under the action of the elastic block and the centering pin. During this process, the elastic block surrounding the centering pin, through its elastic deformation, provides the necessary flexible space and buffer for this relative floating, and continuously provides elastic restoring force to return the second alignment block to its initial position (i.e., without the state of adapting to the second connector rotating along its own axis), ensuring the first connector's reset capability and enhancing the reliability of the blind insertion operation.

[0022] In some embodiments, the first joint includes at least two elastic blocks and at least two centering pins of equal number; At least two elastic blocks are spaced apart circumferentially along the joint body; At least two centering pins are spaced apart along the circumference of the connector body and are partially inserted into the corresponding elastic blocks.

[0023] In this embodiment, by setting the elastic blocks and the centering pins to be arranged in at least two equal sets along the circumferential distance of the joint body, when the second alignment block floats relative to the first alignment block, the multiple circumferentially distributed elastic blocks provide the second alignment block with a balanced elastic restoring force from multiple directions through coordinated deformation, so that it can automatically return to the initial position after any radial offset, thereby enhancing the reliability of the blind mating of the first joint.

[0024] In some embodiments, the first connector further includes a throttle valve having a fluid chamber through which coolant flows; A throttle valve is installed in the accommodating cavity, with one end of the throttle valve connected to the first end and the other end of the throttle valve connected to the second end, so that the coolant flows through the fluid cavity into the heat dissipation device.

[0025] In this embodiment, the flow rate of coolant through the receiving cavity can be adjusted by a throttle valve. Furthermore, by fully utilizing the axial dimensions of the connector body, the throttle valve can be integrated within the connector body, achieving unified liquid cooling water inlet / outlet and floating functions between the server and the rack, better controlling the coolant flow rate, and improving space utilization.

[0033] Figure 1A This is a schematic diagram of the server in an application scenario provided in this application embodiment, showing the overall structure of a server in a liquid-cooled server system provided in this application embodiment.

[0034] Reference Figure 1A As shown, in the example of a liquid-cooled server scenario, the rack 200 is provided with a loading cavity 201, and the server 400 is loaded in the loading cavity 201.

[0035] Here, server 400 can be, but is not limited to, server node, rack server, blade server or high-density server, etc. This application embodiment does not limit the type of server 400.

[0036] The cabinet 200 may be, but is not limited to, rack-mount cabinets, liquid-cooled cabinets, etc. The embodiments of this application do not limit the type of cabinet 200.

[0037] In some embodiments, the server 400 can be inserted into the loading cavity 201 along the loading direction. The loading direction can be... Figure 1A The directions shown in T2 or T3 are parallel or approximately parallel ( Figure 1A The loading direction given is, for example, parallel or approximately parallel to the direction shown in T2.

[0038] In some examples, the loading cavity 201 has an opening 2011 at one end along the loading direction (see...). Figure 1A The opening 2011 is used for the server 400 to be inserted into the loading cavity 201.

[0039] In other embodiments, server 400 may be configured to be directly installed on rack 200. This application does not impose specific restrictions on the connection method between server 400 and rack 200.

[0040] In some implementations, the rack 200 may include a plurality of loading cavities 201 spaced apart along a first direction, each loading cavity 201 for loading a server 400.

[0041] In some examples, the first direction can be understood as the height direction of the rack 200.

[0042] Here, the first direction can intersect with the second or third direction. In other words, T1, T2, and T3 can be the three axes in a three-dimensional coordinate system in Cartesian space.

[0043] Figure 1B This is a schematic diagram of the liquid inlet pipe structure in the application scenario where the server is located.

[0044] In this embodiment, the rack 200 is equipped with liquid cooling pipes. These pipes supply coolant from a cooling unit (not shown) to the heat dissipation devices within the server 400. The liquid cooling pipes include an inlet pipe 211 (see...). Figure 1BThe cooling unit includes an outlet and a return port. The outlet of the cooling unit is connected to an inlet pipe 211, which is connected to the heat dissipation device of the server 400. This allows the cooling unit to transfer coolant to the heat dissipation device of the server 400 via the outlet and inlet pipe. The heat dissipation device of the server 400 is connected to the outlet pipe, which is connected to the return port of the cooling unit. This allows the coolant to absorb heat from the server 400 and then be transferred to the cooling unit via the return pipe and return port.

[0045] In some embodiments, the heat dissipation device may include a cold plate. The cold plate has a cooling cavity for coolant to flow through. The inlet end of the cold plate is connected to the inlet pipe 211 so that coolant flows into the cooling cavity from the inlet pipe 211 and the inlet end. The outlet end of the cold plate is connected to the outlet pipe so that the coolant flowing through the cooling cavity is transferred back to the cooling unit through the outlet pipe.

[0046] Figure 1C This is a partial structural diagram of a server provided in an embodiment of this application. (Refer to...) Figure 1C As shown, in some embodiments, server 400 includes chassis 410. Chassis 410 is provided with a first connector 100.

[0047] Here, the first connector 100 can be a liquid-cooled male connector. The first connector 100 can be configured on the liquid inlet or return line between the server 400 and the cooling unit, and is used to connect to the heat dissipation device inside the chassis 410. The heat dissipation device is used to dissipate heat from the server 400.

[0048] In some embodiments, the first connector 100 may be configured on the liquid inlet pipe for connection between the liquid inlet pipe and the liquid cooling device, so as to realize the transfer of coolant from the cooling unit to the heat dissipation device of the server 400. For example, the first connector 100 is connected between the inlet end of the cold plate and the liquid inlet pipe 211, so that coolant flows into the cooling chamber from the liquid inlet pipe 211 and the first connector.

[0049] In some embodiments, the first connector 100 may also be configured on the liquid outlet pipe for connecting the liquid cooling device and the liquid outlet pipe to transfer coolant from the heat dissipation device of the server 400 to the cooling unit. For example, the first connector 100 is connected between the outlet end of the cold plate and the liquid outlet pipe so that the coolant flowing through the cooling chamber is transferred back to the cooling unit via the first connector 100 and the liquid outlet pipe.

[0050] Accordingly, in some embodiments, the cabinet 200 is provided with a second connector 220. The second connector 220 is used to mate with the first connector 210 to form a quick-connect connector.

[0051] Here, the second connector 220 can be a liquid-cooled female connector.

[0052] In some examples, quick-connect fittings can be configured on the inlet line to connect the outlet of the cooling unit to the inlet of the cold plate, so as to transfer coolant from the cooling unit to the liquid cooling device of the server 400.

[0053] In some examples, the quick-connect fitting can also be configured on the liquid outlet line to connect between the outlet end of the cold plate and the return port of the cooling unit, so as to transfer coolant from the liquid cooling device of the server 400 to the cooling unit.

[0054] Reference Figure 1B As shown, in some embodiments, the second connector 220 is located on the liquid inlet pipe 211 and is configured to connect to the first connector 210 located on the liquid inlet pipe when the server 400 is installed in the rack 200. Thus, the liquid outlet of the cooling unit is connected to the heat dissipation device of the server 400 through the first connector 210 and the second connector 220.

[0055] The following are some implementation methods for arranging the liquid inlet pipe 211 and the cabinet 200.

[0056] In one embodiment, the liquid inlet pipe 211 can be located inside the cabinet 200, and the first connector 210 and the second connector 220 are aligned so that when the server 400 is loaded into the loading cavity 201, the first connector 210 and the second connector 220 are plugged in.

[0057] Here, the inner side of the cabinet 200 can be understood as the side of the cabinet 200 used to set up the loading cavity 201.

[0058] In some examples, the liquid inlet pipe 211 includes a connecting wall 230, which can be connected to the inner wall of the cabinet 200 in a third direction, so that the liquid inlet pipe 211 is located inside the cabinet 200, and the second connector 220 is located on the side of the liquid inlet pipe 211 near the loading cavity 201 for insertion with the first connector 210.

[0059] Among them, the third direction can be the width direction of the server 400, which is perpendicular or approximately perpendicular to the loading direction; and the third direction is perpendicular or approximately perpendicular to the spacing direction of the multiple loading cavities 201 (which can be understood as the first direction mentioned above).

[0060] In another embodiment, the liquid inlet pipe 211 can be located on the outside of the cabinet 200, and the second connector 220 is located on the side of the liquid inlet pipe 211 closer to the cabinet 200. Accordingly, the cabinet 200 has a through hole in the side wall corresponding to the liquid inlet pipe 211, so that the first connector 210 and the second connector 220 can be connected through the through hole.

[0061] In some examples, the liquid inlet pipe 211 can be located outside the side wall of the cabinet 200 along the third direction, so that the liquid inlet pipe 211 is located outside the cabinet 200, and the second connector 220 is located on the side of the liquid inlet pipe 211 near the loading cavity 201 for insertion with the first connector 210.

[0062] Figure 1D yes Figure 1B The enlarged structural diagram of point A in the liquid inlet pipe shows the insertion structure of the first connector and the second connector. Figure 2A This is a schematic diagram of the structure of the first connector in a server provided in an embodiment of this application.

[0063] Reference Figure 2A As shown in the embodiment of this application, the first connector 100 includes a connector body 10. The connector body 10 is provided with a receiving cavity 101, and the connector body 10 has a first end 11 and a second end 12. The first end 11 is used to connect with the second connector 220, and the second end 12 is connected with the heat dissipation device so that the coolant flows through the receiving cavity 101 into the heat dissipation device.

[0064] Reference Figure 1C In the example, server 400 includes a liquid inlet pipe 414, which connects the heat sink and the connector body 10 to transfer coolant through the receiving cavity 101 in the connector body 10 and the liquid inlet pipe 414 to the heat sink. In other words, the second end 12 of the connector body 10 is connected to the heat sink through the liquid inlet pipe 414.

[0065] Similarly, in other examples, server 400 may also include a coolant outlet pipe (not shown) connected between the heat dissipation device and connector body 10 to transfer coolant absorbing heat from server 400 through the receiving cavity 101 within connector body 10 and the coolant outlet pipe to the cooling unit. In other words, the second end 12 of connector body 10 is connected to the heat dissipation device via the coolant outlet pipe.

[0066] Reference Figure 1D As shown, in some embodiments, the first connector 100 further includes a first mating member 300, one end of which is connected to the first end 11 of the connector body 10, and the other end of which is used to connect to the second connector 220. Correspondingly, the second connector 220 further includes a second mating member 221, and the first mating member 300 and the second mating member 221 are inserted into each other to realize the insertion of the first connector 100 and the second connector 220.

[0067] In some examples, the inner diameter of the second mating member 221 is larger than the outer diameter of the first mating member 300. In this case, the first mating member 300 is inserted into the second mating member 221 to achieve the connection between the two.

[0068] Reference Figure 2A As shown, in some embodiments, the first connector 100 is provided with a guide sleeve 61 extending axially along the first connector 100, and the second connector 220 is provided with a guide pin 223 extending axially along the second connector 220. During the insertion of the server 400 into the rack 200 along the loading direction, the guide pin 223 on the rack 200 first inserts into the guide sleeve 61, which moves with the server 400. Through the cooperation of the guide pin 223 and the guide sleeve 61, the alignment of the first mating member 300 and the second mating member 221 is completed before they contact each other, ensuring the accuracy and reliability of the subsequent sealing connection.

[0069] Here, the alignment of the first mating part 300 and the second mating part 221 can be understood as follows: under the cooperation of the guide pin 223 and the guide sleeve 61, the axis of the first mating part 300 and the axis of the second mating part 221 are collinear or nearly collinear. At the same time, the projection of the center of the axis of the first mating part 300 and the center of the axis of the second mating part 221 on the axial direction of the first mating part 300 coincides or nearly coincides, thus providing a basis for their insertion.

[0070] The criteria for judging near collinearity are as follows: the offset of the axis of the first docking member 300 and the axis of the second docking member 221 in the radial direction of the second docking member 221 is within the allowable range for the first docking member 300 and the second docking member 221 to be inserted; the criteria for judging near coincidence are as follows: the offset of the center of the axis of the first docking member 300 relative to the center of the axis of the second docking member 221 in the radial direction of the second docking member 221 is within the allowable range for the first docking member 300 and the second docking member 221 to be inserted.

[0071] In some embodiments, the second connector 220 further includes a mounting member 222, which is disposed on the inlet pipe 211 or the outlet pipe. Accordingly, the guide pin 223 can be connected to the mounting member 222 and protrudes from the mounting member 222 in the insertion direction to cooperate with the guide sleeve 61.

[0072] In some implementations, due to the accumulation of manufacturing and assembly tolerances of the rack 200 and server 400, and the dynamic offset of the server 400 during loading into the loading cavity 201, the actual positions of the first connector 100 and the second connector 220 may deviate from the theoretical mating positions. This mating position deviation may include: misalignment (axial deviation) between the axis of the second connector 220 and the axis of the first connector 100; or misalignment (axial deviation) between the second connector 220 and the first connector 210 in a plane perpendicular to the insertion direction. Figure 1D(The arrow q in the image exemplifies a direction on the plane) There is a misalignment (radial deviation); the axial direction of the second connector 220 is at an angle (angular deviation) to the axial direction of the first connector 100, which causes the first mating piece 300 of the first connector 100 to be unable to be inserted into the second mating piece 221 of the second connector 220.

[0073] Figure 2B yes Figure 2A The exploded structural diagram of the first joint shows its structural composition. Figure 2C yes Figure 2A The diagram shows the axial cross-sectional structure of the first joint.

[0074] Combination Figures 2A to 2C As shown in the embodiment of this application, the first connector 100 includes a connector body 10. The connector body 10 is provided with a receiving cavity 101. The first end 11 of the connector body 10 is connected to the second connector 220, and the second end 12 of the connector body 10 is connected to the heat dissipation device, so that the coolant flows through the receiving cavity into the heat dissipation device.

[0075] In some embodiments, the receiving cavity 101 extends through the connector body 10 along its axial direction to connect the first end 11 and the second end 12. Thus, coolant can flow through the receiving cavity 101 via the first end 11 and the second end 12.

[0076] Here, the axial direction of the connector body 10 can be consistent with the direction in which the first connector 100 and the second connector 220 are inserted.

[0077] Here, the technical solutions for connecting the first end 11 to the second connector 220 and the technical solutions for connecting the second end 12 to the heat dissipation device can be referred to the foregoing description, and will not be repeated here.

[0078] Combination Figure 1C , Figures 2A to 2C As shown in this embodiment, the first connector 100 further includes a mounting base 30. The mounting base 30 is connected to the connector body 10 and to the chassis 410. Thus, the first connector 100 is pre-installed on the server 400 via the mounting base 30. Accordingly, when the server 400 is installed in the rack 200, the first connector 100 is plugged into the second connector 220 to allow coolant to be transferred between the cooling unit and the heat dissipation device.

[0079] It should be noted that, Figure 1C The diagram shows the structure of the chassis 410 without the top cover. In some embodiments, the mounting base 30 is provided with mounting holes 32, and fasteners are inserted through the top cover of the chassis 410 and the mounting holes to connect the mounting base 30 and the chassis 410.

[0080] In this embodiment, the mounting base 20 and the chassis 410 are connected by fasteners. This is only an example of the connection between the mounting base 20 and the chassis 410. This embodiment does not impose specific restrictions on the connection method between the mounting base 20 and the chassis 410.

[0081] Figure 2D yes Figure 2A The diagram shows the structure of the connector body in the first connector.

[0082] Combination Figure 2C and Figure 2D As shown in the embodiment of this application, the first connector 100 further includes a first alignment block 20. The first alignment block 20 is sleeved on the first part 15 of the connector body 10, and the first alignment block 20 has a first gap d1 between itself and the first part 15 of the connector body 10 along the radial direction. The first gap d1 is used to allow the connector body 10 to move radially (unless otherwise specified, radial direction is understood as the radial direction of the connector body 10) during the insertion of the first connector 100 and the second connector 220, so as to absorb the dimensional tolerance between the connector body 10 and the second connector 220 in the radial direction, that is, to adjust the position of the connector body 10 in the radial direction so that it can be aligned radially with the second connector 220 during insertion.

[0083] Here, the first gap d1 can be understood as the gap between the outer wall of the first part 15 in the axial direction and the inner wall of the first alignment block 20 in the axial direction. As a result, the connector body 10 can move relative to the first alignment block 20 within the radial space defined by the first gap d1.

[0084] In some embodiments, the range of movement of the connector body 10 along its own radial direction is positively correlated with the size of the first gap d1.

[0085] In some examples, the larger the radial dimension of the first gap d1, the greater the range of movement of the connector body 10 along its own radial direction. In other examples, the smaller the radial dimension of the first gap d1, the smaller the range of movement of the connector body 10 along its own radial direction. Here, the radial dimension of the first gap d1 can be understood as the distance between the outer wall of the first part 15 in the axial direction and the inner wall of the first alignment block 20 in the axial direction along the radial direction of the connector body 10.

[0086] Reference Figure 2B and Figure 2CAs shown in this embodiment, the first connector 100 further includes an axial elastic element 40. The axial elastic element 40 is disposed between the mounting base 30 and the first alignment block 20, and provides a first elastic force along the axial direction of the connector body to the first alignment block 20. This first elastic force allows the first alignment block 20 to move axially during the insertion of the first connector 100 and the second connector 220. Correspondingly, the connector body 10 is used to move axially under the drive of the first alignment block 20 to axially align with the second connector.

[0087] In the above scheme, in the initial state (before the first connector 100 is mated with the second connector 220), the axial elastic element 40 is at its free length. There is an axial assembly gap between the first alignment block 20 and the connector body 10.

[0088] During the process of connecting the first connector 100 and the second connector 220, due to the fixed liquid cooling pipes of the cabinet 200, the first connector 100 is subjected to an axial force from the side of the cabinet 200. Under the action of this axial force, the first alignment block 20 and the connector body 10 move towards the inside of the server relative to the mounting base 30 until they are axially close together and the axial assembly gap is eliminated.

[0089] After the axial assembly clearance is eliminated, axial force begins to act on the axial elastic element 40, causing it to be compressed from its free state and undergo elastic deformation. As deformation occurs, the axial elastic element 40, based on its elastic properties, generates a first elastic force along the axial direction of the connector body 10, pointing towards the second connector 220. Subsequently, if the axial force continues to increase (for example, if the first connector 100 and the second connector 220 are axially interlocked), this axial force will overcome the gradually increasing first elastic force, further compressing the axial elastic element 40 and driving the first alignment block 20 and the connector body 10 to continue moving relative to the mounting base 30 into the server interior, absorbing the axial dimensional tolerances between the first connector 100 and the second connector 220.

[0090] Furthermore, when the first connector 100 is pulled out of the second connector 220, the axial force disappears. Under the action of the first elastic force of the axial elastic member 40, the first alignment block 20 and the connector body 10 will return to their initial positions. In these initial positions, there may be an axial assembly gap between the first alignment block 20 and the connector body 10 for the next insertion.

[0091] According to an embodiment of this application, a server 400 is provided: On one hand, a first alignment block 20 is sleeved on a first part of the connector body, and an axial elastic element 40 is disposed between the mounting base 30 and the first alignment block 20; when the first connector 100 is subjected to an axial force from the second connector 220, the axial force is transmitted to the axial elastic element 40 through the first alignment block 20. The axial elastic element 40, through its own compression deformation, allows the first alignment block 20 and the connector body 10 to move together axially to absorb axial mating tolerances. On the other hand, a first gap d1 is disposed in the radial gap between the first alignment block 20 and the connector body 10. When the first connector 100 mates with the second connector 220, the connector body 10 can float radially relative to the first alignment block 220 within the range determined by the first gap d1 to achieve radial mating with the pipeline, i.e., absorb radial mating tolerances. As can be seen, this design achieves structural decoupling of the radial and axial floating functions of the connector body 10 by placing the elastic element between the mounting base 30 and the first alignment block 20, and by setting a first gap between the first alignment block 20 and the connector body 10. In other words, axial and radial floating occur between different mating surfaces of the first connector 100, and the force required for floating is provided by different components. This makes the radial and axial floating of the connector body 10 independent of each other and does not interfere with each other, improving the floating effect and enhancing the reliability and convenience of blind insertion operation between the first connector 100 and the second connector 220. At the same time, the axial floating of the first connector 100 no longer needs to overcome the frictional resistance of the radial floating surface, thus reducing the compressive force required by the axial elastic element 40; simultaneously, the radial floating is no longer affected by the component force of the first elastic force, making the floating more sensitive. These factors together improve the overall floating effect of the first connector 100.

[0092] Furthermore, since the radial and axial floating of the connector body 10 are independent of each other, the adaptability of the first connector 100 to dimensional tolerances is improved, and it can be compatible with multiple second connector 220 designs with different axial and radial tolerances, thereby improving the versatility of the server 400.

[0093] In some embodiments, the axial elastic element 40 is configured to have a preload along the axial direction p, and the preload is greater than the insertion and extraction force required to be overcome when mating with the second connector 220.

[0094] Here, the insertion and extraction force can be understood as the reverse force generated by the sealing, locking and other structures of the second connector 220 when the first connector 100 and the second connector 220 are connected.

[0095] It should be noted that the insertion and extraction force can be determined by consulting standard manuals such as quick connector design specifications, and will not be elaborated here.

[0096] At this point, when the server 400 is pushed into the rack 200, both the axial elastic element 40 and the connector body 10 are in their initial positions. In these initial positions, the axial elastic element 40, due to pre-compression, applies a pre-stress to the first alignment block 20 in the direction of the second connector 220. This pre-stress is used to eliminate any gaps along the axial direction of the connector body 10 between the connector body 10, the first alignment block 20, and the axial elastic element 30.

[0097] During the insertion of the first connector 100 and the second connector 220, the first mating member 300 and the second mating member 221 come into contact, and the first connector is subjected to an insertion and extraction force from the second connector 220 in the opposite direction to the insertion direction. Since the prestress of the axial elastic member 40 is greater than this insertion and extraction force, the prestress can overcome the insertion and extraction force, allowing the first alignment block 20 and the connector body 10 to continue moving towards the second connector 220 to complete the insertion. Thus, when the server 400 is inserted into the rack 200 to allow the first connector 100 and the second connector 220 to mate, no additional external thrust (the force that inserts the server 400 into the rack 200) is required to initiate the docking. The prestress design ensures a smooth and reliable docking action, avoiding impact.

[0098] When the first connector 100 and the second connector 220 are properly inserted, the first connector 100 and the second connector 220 form a "self-stopping effect". The self-stopping effect can be understood as follows: if the server 400 continues to be pushed into the receiving cavity 201, the second connector 220 will apply a larger axial thrust to the first connector 100, and the axial elastic element 40 will continue to be compressed under this axial thrust, so that the first alignment block 20 and the connector body 10 move axially into the server 400, preventing the first connector 100 and the second connector 220 from being excessively squeezed, and protecting the server 400 and the cabinet 200.

[0099] In some embodiments, the first connector 100 may include an axial elastic element 40 disposed between the first alignment block 20 and the mounting base 30.

[0100] In other embodiments, the first connector 100 includes at least two axial elastic elements 40, which can be arranged circumferentially at intervals along the first alignment block 20 so that the insertion and extraction force on the first connector 100 is evenly applied to the at least two axial elastic elements 40, thereby reducing the pre-pressure required for each axial elastic element 40 and improving the configuration flexibility of the axial elastic elements 40.

[0101] The number of axial elastic elements 40 can be 2, 3, 4 or other numbers. This application embodiment does not impose a specific limitation on the number of axial elastic elements 40.

[0102] In some examples, the first connector 100 includes two axial elastic elements 40, each of which is connected axially between the first alignment block 20 and the mounting base 30 along the axial direction of the connector body 10; and the two axial elastic elements 40 are symmetrically arranged with respect to the central axis of the connector body 10 so that the insertion and extraction forces on the two axial elastic elements 40 are symmetrical, avoiding excessive pressure on one side.

[0103] Figure 3 This is a schematic diagram of a server with the first connector removed from its mounting base, provided in an embodiment of this application.

[0104] Reference Figure 3 In the example shown, the first connector 100 includes four axial elastic elements 40, each of which is connected between the first alignment block 20 and the mounting base 30 along the axial direction of the connector body 10; and the four axial elastic elements 40 are symmetrically arranged with respect to the central axis of the connector body 10 so that the insertion and extraction forces on the four axial elastic elements 40 are symmetrical, thereby avoiding excessive pressure on one side of the first connector 100.

[0105] In some examples, the axial elastic element 40 can be a spring, elastic foam, or other elastic structure. This application embodiment does not limit the type of axial elastic element 40.

[0106] In some embodiments, the first connector 100 further includes a guide 41, which is axially connected between the mounting base 30 and the first alignment block 20 along the connector body 10; the axial elastic member 40 is sleeved on the guide 41. Thus, the guide 41 can provide guidance for the deformation process of the axial elastic member 40, effectively preventing the axial elastic member 40 from deflecting or becoming unstable during deformation, and improving the reliability of the axial movement of the connector body 10 under the action of the axial elastic member 40.

[0107] Reference Figure 2B As shown, the guide member 41 can be a bolt, guide rod or other guide structure. This application embodiment does not impose specific restrictions on the type of guide member 41.

[0108] Figure 4A This is a schematic diagram of the structure of a mounting base for the first connector in a server provided in an embodiment of this application.

[0109] Reference Figure 4A As shown, in some embodiments, the mounting base 30 is provided with a first connecting hole 31 extending along the axial direction p, and the guide member 41 can be inserted into the first connecting hole 31 to achieve a fixed connection with the mounting base 30.

[0110] In some examples, the guide 41 may be interference-fitted into the first connection hole 31.

[0111] In other examples, the guide 41 is provided with a first external thread at one end for connection to the mounting base 30, and the first connecting hole 31 is provided with a first internal thread. The guide 41 and the mounting base 30 are fixedly connected by the first external thread and the first internal thread.

[0112] Figure 4B This is a schematic diagram of the structure of a guide component for the first connector in a server, provided in an embodiment of this application.

[0113] Reference Figure 4B In the examples shown, in some cases, the guide 41 may include a first segment 411, a second segment 412, and a third segment 413 connected axially p. In other words, the second segment 412 is connected between the first segment 411 and the third segment 413. The second segment 412 is used to accommodate the axial elastic element 40, and the first segment 411 has a first external thread (not shown in the figure, the end position of the external thread is schematically indicated by a dashed line). The third segment is movably connected within the first alignment block 20 so that the first alignment block 20 can move axially p relative to the mounting base 20 during the mating of the first connector 100 and the second connector 220.

[0114] In other words, the guide 41 passes through the first connecting hole 31 and extends into the first alignment block 20, so that the first section 411 is threadedly connected to the first connecting hole 31, thereby achieving a fixed connection between the guide 41 and the mounting base 30; the axial elastic member 40 is sleeved on the second section 412 to abut against the mounting base 30 and the first alignment block 20.

[0115] Figure 5 This is a schematic diagram of the structure of the first alignment block of the first connector in a server provided in an embodiment of this application.

[0116] Reference Figure 5 As shown, in some embodiments, the first alignment block 20 is provided with a second connecting hole 21 extending along the axial direction p, and the guide member 41 can pass through the second connecting hole 21 to achieve a movable connection with the first alignment block 20. Thus, the first alignment block 20 can move relative to the mounting base 30 along the axial direction p.

[0117] In some embodiments, the first connector 100 further includes an elastic reset member 50, which is sleeved on the first portion 15 and located between the first portion 15 and the first alignment block 20; the elastic reset member 50 provides a second elastic force in the radial direction to the first alignment block 20, the second elastic force being used to maintain or restore the first central axis of the connector body 10 and the second central axis of the first alignment block 20 to be in a state of coincidence.

[0118] In the above scheme, when the first connector 100 is not inserted into the second connector 200, that is, when the first connector 100 is in a free state, the first central axis (axial p) and the second central axis coincide. At this time, when the first connector 100 is subjected to vibration, the elastic reset member 50 will apply elastic force to the first alignment block 20 and / or the connector body 10, so that the first central axis (axial p) and the second central axis are in a coincident state.

[0119] During the insertion process of the first connector 100 and the second connector 220, if there is a radial deviation between the second connector 220 and the first connector 100, the second connector 220 will apply a radial offset force to the connector body 10. When the offset force is greater than the second elastic force, the offset force will push the connector body 10 to undergo radial relative displacement relative to the first alignment block 20. At this time, there is a radial offset between the first central axis (axial direction p) and the second central axis. Finally, the second elastic force and the offset force reach a balance, stabilizing the connector body 10 at this radially offset position, and the first connector 100 and the second connector 220 are stably inserted.

[0120] When the first connector 100 is pulled out from the second connector 220, the offset force acting on the first connector 100 is removed. Under the action of the second elastic force of the elastic reset member 50, the connector body 10 moves radially, so that the first central axis (axial p) and the second central axis are restored to the coincident state.

[0121] It should be noted that the overlap here is a theoretical overlap. In practical applications, due to manufacturing or assembly tolerances, there may be deviations within the allowable range between the first and second center axes.

[0122] According to the server 400 provided in the embodiments of this application: by introducing an elastic reset member 50, while ensuring that the first connector 100 is provided with radial floating function by the first gap d1, the ability of the connector body 10 to automatically reset radially to the first central axis and the second central axis to coincide is realized, so that the connector body 10 can be stably in the centering state, which is convenient to be plugged into the second connector 220 again, and improves the reliability of the long-term permissible plugging of the first connector 100 and the second connector 220 in blind plugging operation.

[0123] In some embodiments, the radial limit compression of the elastic reset member 50 is matched with the maximum radial floating displacement defined by the first gap d1, so as to avoid the elastic reset member 50 being over-compressed and failing or being damaged when the connector body 10 moves radially to the limit position of the first gap d1.

[0124] The extreme position of the first gap d1 can be understood as the farthest position where the first central axis of the connector body 10 can deviate radially from the second central axis of the first alignment block 20 when the connector body 10 moves within the first gap d1. Correspondingly, the maximum radial floating displacement is the axial distance between the first central axis and the second central axis at this extreme position.

[0125] In addition, the radial limit compression of the elastic reset member 50 can be understood as the maximum radial deformation that the elastic reset member 50 can produce before it fails after being radially compressed from a free state.

[0126] It should be noted that, for ease of description, since the elastic reset member 50 is sleeved on the connector body 10, the elastic reset member 50 can be divided into two opposing parts in the radial direction: a first part (located on the opposite side of the offset direction) and a second part (located on the same side of the offset direction). When the connector body 10 is radially offset, the second part is compressed and is the main part that provides the restoring force; the first part is released or the amount of compression is reduced.

[0127] In some examples, the radial limit compression of the elastic reset member 50 is equal to the maximum radial floating displacement allowed by the first gap d1. At this time, when the connector body 10 moves radially to its limit position, the first part of the elastic reset member 50 also reaches its own radial limit compression. In other words, the radial compression stroke of the elastic reset member 50 is designed to ensure that its limit position is synchronized with the radial floating limit of the connector body 10; that is, when the connector body 10 moves radially to its limit position, the elastic reset member 50 on the pressure side (second part) also just reaches its radial limit compression.

[0128] In other examples, the radial limit compression of the elastic reset member 50 is greater than the maximum radial floating displacement allowed by the first gap d1. In this case, when the connector body 10 moves radially to the limit position, although the first part of the elastic reset member 50 is compressed, its compression amount is still less than its own radial limit compression amount, leaving a safety margin and providing higher reliability.

[0129] In some embodiments, the first connector further includes a first stop portion 13 and a second stop portion 14, the first stop portion 13 and the second stop portion 14 being axially spaced apart on the outer side of the connector body 10, and the elastic reset member 50 abutting against the first stop portion 13 and the second stop portion 14 axially.

[0130] According to the embodiments of this application, the first connector 100 includes a first stop portion 13 and a second stop portion 14, which are spaced axially on the outside of the connector body 10. This allows the elastic reset member 50 to be constrained along its own axial direction and abut against the first stop portion 13 and the second stop portion 14. The first stop portion 13 and the second stop portion 14 provide a clear and fixed axial bearing surface for the elastic reset member 50, ensuring that it can be stably compressed axially. This prevents the elastic reset member 50 from experiencing uneven wear or instability during long-term use, and improves the long-term reliability of the connection between the first connector 100 and the second connector 220 during blind insertion operations. That is, after repeated blind insertion operations, the first connector 100 can still maintain consistent reset accuracy and reliable docking performance to meet long-term operational stability requirements.

[0131] Hereinafter, some exemplary embodiments of the first stop portion 13 and the second stop portion 14 are given.

[0132] As one example, the first stop portion 13 and the second stop portion 14 can be configured to be formed by the outer wall of the connector body 10 extending outward along the circumference of the connector body 10 (not shown).

[0133] In some examples, along the axial direction of the connector body 10, the first stop 13 and the second stop 14 are located on opposite sides of the first alignment block 20 along its own axial direction, so as to increase the arrangement space of the elastic reset member 50, increase the range of its force with the first alignment block 20, avoid the possible jamming caused by unilateral support, and ensure the smoothness and stability of the reset process.

[0134] In other examples, along the axial direction of the connector body 10, the projections of the first stop portion 13 and the second stop portion 14 both fall within the first alignment block 20, that is, the first stop portion 13 and the second stop portion 14 are located within the radial gap between the first alignment block 20 and the connector body 10, so as to save radial space and make the structure compact.

[0135] Combination Figure 2B and Figure 2C As shown, as another example, the first connector 100 also includes a stop member 53, which is sleeved on the third part 17 of the connector body 10. That is, the stop member 53 and the first alignment block 20 are sequentially sleeved on the connector body 10 along the axial direction. Thus, the side end face of the stop member 53 facing the first alignment block 20 along the axial direction serves as the first stop portion 13, so that one end of the elastic reset member 50 along the axial direction abuts against the first stop portion 13, that is, against the stop member 53.

[0136] In some examples, the stop 53 and the first alignment block 20 are flush with each other on one side along the axial direction. In this case, the side of the elastic reset member 50 near the stop 53 is located in the first gap d1 between the first alignment block 20 and the connector body 10, reducing the occupancy of axial space.

[0137] In other examples, the stop 53 and the first alignment block 20 are spaced apart axially, and the side of the elastic reset member 50 near the stop 53 extends beyond the first gap d1 between the first alignment block 20 and the connector body 10, making the configuration of the elastic reset member 50 more flexible.

[0138] In some embodiments, the stop 53 is provided with a third internal thread, and the third part 17 is provided with a third external thread 181. The stop 53 is sleeved on the third part 17 through the cooperation of the third internal thread and the third external thread 181.

[0139] It should be noted that the threaded connection between the stop 53 and the connector body 10 is only an example of the connection method between the stop 53 and the connector body 10. It can also be connected by integral molding, interference fit, etc. The embodiments of this application do not limit the connection method between the stop 53 and the connector body 10.

[0140] Combination Figure 2C and Figure 2D As shown, the first connector 100 further includes a second alignment block 60, which is sleeved on the second part 16 of the connector body 10. The side end face of the second alignment block 60 facing the first alignment block 20 along the axial direction serves as a second stop portion 14, so that the other end of the elastic reset member 50 along the axial direction abuts against the second stop portion 14, that is, against the second alignment block 60. In other words, along the axial direction of the connector body 10, the stop member 53 and the second alignment block 60 are respectively located on both sides of the first alignment block 20, and their side end faces facing the first alignment block 20 along the axial direction respectively serve as the first stop portion 13 and the second stop portion 14.

[0141] Figure 6 This is a schematic diagram of the structure of the connector body, the first alignment block, and the second alignment block of a first connector in a server, provided in an embodiment of this application. (Combined with...) Figure 3 and Figure 6 As shown, in some embodiments, the first inner diameter d2 of the second alignment block 60 is smaller than the second inner diameter d3 of the first alignment block 20, thereby forming a second stop portion 14 on the end face of the second alignment block 60 axially toward the first alignment block 20 (see also...). Figure 11 ), for the elastic reset element 50 to abut.

[0142] Here, the first inner diameter d2 can be understood as the radial dimension of the inner wall of the second alignment block 60 on the side closest to the first alignment block 20 along the axial direction. The second inner diameter d3 can be understood as the radial dimension of the inner wall of the area of ​​the first alignment block 10 used to accommodate the elastic reset member 60.

[0143] In some embodiments, the second alignment block 60 is provided with a fourth internal thread 63 (see...). Figure 8The second part 16 is provided with a fourth external thread 161. The second alignment block 60 is sleeved on the second part 16 through the cooperation of the fourth internal thread 63 and the fourth external thread 161. The second part 16 is also used to sleeve the elastic reset member 50.

[0144] It should be noted that the threaded connection between the second alignment block 60 and the connector body 10 is only an example of the connection method between the second alignment block 60 and the connector body 10. It can also be connected by integral molding, interference fit, etc. The embodiments of this application do not limit the connection method between the second alignment block 60 and the connector body 10.

[0145] In some examples, the elastic reset member 50 can be configured as an elastic structure such as a spring, elastic foam, silicone part or rubber part. The embodiments of this application do not limit the type of elastic reset member 50.

[0146] In some embodiments, the inner wall of the first alignment block 20 is provided with a protrusion 22 protruding outward. The elastic reset member 50 includes a first pagoda spring 51 and a second pagoda spring 52. The two ends of the first pagoda spring 51 along the axial direction abut against the first stop portion 13 and the protrusion 22, respectively; the two ends of the second pagoda spring 52 along the axial direction abut against the protrusion 22 and the second stop portion 14, respectively.

[0147] Here, the pagoda spring (first pagoda spring 51 and / or second pagoda spring 52) can be understood as follows: in the axial direction of the connector body 10, the mean diameter of the spring gradually increases or decreases in the direction away from the protrusion 22. Here, "mean diameter" can be understood as the diameter at which the helical centerline of the spring is located. It is numerically equal to the arithmetic mean of the inner diameter and outer diameter of the spring.

[0148] In some other embodiments of this application, the elastic reset member 50 may also include a first pagoda elastic member and a second pagoda elastic member. That is, in the axial direction of the connector body 10, the outline size of the pagoda elastic member (first pagoda elastic member or second pagoda elastic member) gradually increases or decreases in the direction away from the protrusion 22, so as to present a pagoda shape as a whole.

[0149] In some embodiments, the implementation of the first pagoda elastic element and / or the second pagoda elastic element can refer to the technical solutions of "first pagoda spring 51 and / or second pagoda spring 52" described below, and will not be repeated here.

[0150] According to the server 400 provided in the embodiments of this application: a protrusion 22 is provided on the inner wall of the first alignment block 20, and the elastic reset member 50 is configured as a first pagoda spring 51 and a second pagoda spring 52 located on both sides of the protrusion 22, forming a series of elastic supports. When the connector body 10 is radially offset relative to the first alignment block 20, the pagoda spring on the offset side is compressed, while the pagoda spring on the opposite offset side is stretched or maintains support; the protrusion 22, as the intermediate force transmission and guiding member, effectively couples the forces of the two springs, which act together on the connector body 10, providing a restoring force pointing towards the radial center of the connector body 10. Thus, by utilizing the characteristics of the pagoda spring, the radial support stiffness is enhanced, thereby improving the centering reset accuracy and docking reliability of blind mating. In addition, when the pagoda spring is subjected to axial torsional force along the connector body 10, the structural characteristics of the pagoda spring can absorb the tolerance, making the torsion smoother (described later).

[0151] In other words, based on the conical structure of the pagoda spring, the restoring force provided by its deformation can be decomposed into radial and axial components along the connector body 10. Through the elastic design, it can be ensured that the resultant force of the radial components of the two pagoda springs is greater than the overall weight of the first connector 100, so that the first connector 100 can resist the influence of its own weight in the direction of gravity, achieving stable and accurate automatic centering, effectively preventing natural sagging caused by gravity, and ensuring centering accuracy.

[0152] In some embodiments, the protrusion 22 may be configured to protrude from the inner wall of the first alignment block 20 toward the side facing the first gap d1.

[0153] In some examples, there is only one protrusion 22. The protrusion 22 can be constructed to continuously protrude along the circumference of the first alignment block 20 on the inner wall of the first alignment block 20, so as to enhance the contact area between the first pagoda spring 51 and the second pagoda spring 52 and the protrusion 22, improve the uniformity of the pagoda spring (the first pagoda spring 51 and the second pagoda spring 52) when it deforms, and improve the overall structural stability.

[0154] In other examples, there are multiple protrusions 22, which can be configured to protrude from the inner wall of the first alignment block 20 at circumferential intervals.

[0155] In some embodiments, the first pagoda spring 51 and the second pagoda spring 52 are symmetrically arranged based on the protrusion 22. In other words, the variation trend of the mean diameter of the springs in the direction away from the protrusion 22 along the axial direction of the connector body 10 is consistent.

[0156] In some examples, the mean diameters of the first pagoda spring 51 and the second pagoda spring 52 gradually increase in the axial direction of the connector body 10 and in the direction away from the protrusion 22, and the increasing trend is consistent.

[0157] Reference Figure 2C As shown, in other examples, along the axial direction of the connector body 10, in a direction away from the protrusion 22, the mean diameters of the first pagoda spring 51 and the second pagoda spring 52 gradually decrease and the decreasing trend is consistent. In this case, the large end (the end with the larger mean diameter) of the pagoda spring faces the protrusion 22, and the small end (the end with the smaller mean diameter) faces the stop (corresponding to the first stop 13 or the second stop 14). The small end requires less radial movement space, and when the pagoda spring is compressed in an inclined state (described later), the risk of it jamming with the inner wall of the first alignment block 20 is lower, improving the reliability of the centering function.

[0158] Therefore, the symmetrical design ensures that when the connector body 10 undergoes radial displacement, the force arms of the two pagoda springs on both sides of the protrusion 22 are symmetrical with the force conditions, making the second elastic force generated by the two pagoda springs equal in magnitude, opposite in direction, and radially pointing towards the radial center of the connector body 10. Correspondingly, the symmetrical arrangement prevents uneven wear, jamming, or unilateral wear that may be caused by uneven force on the pagoda springs, and improves the ability of the connector body 10 to automatically return to the first and second central axes, so that the connector body 10 can be stably aligned, facilitating re-insertion with the second connector 220, and improving the reliability of the long-term permissible insertion of the first connector 100 and the second connector 220 during blind insertion operations.

[0159] Figure 7A yes Figure 2C The diagram shows a cross-sectional view of the first joint tilted to its limit along its own axis. In Figure 7, the dashed line p' indicates the position of the central axis of the joint body 10 when it is at its tilt angle limit.

[0160] Reference Figure 2C and Figure 7A As shown, in some embodiments, due to manufacturing or assembly errors, the actual axial direction of the second connector 220 may deviate from its theoretical axial direction by an angle. Utilizing the structural characteristics of the first pagoda spring 51 and the second pagoda spring 52, the connector body 10 can be tilted at a certain angle along a point on its own axis, thereby adaptively aligning with the second connector 220.

[0161] In some embodiments, the greater the difference (which can be understood as taper) between the large and small end diameters of the pagoda spring (which can be either the first pagoda spring 51 or the second pagoda spring 52) along the axial direction of the connector body 10, the greater the limit of the tilt angle that the connector body 10 can achieve. This tilt angle limit refers to the maximum angle that the connector body 10 can tilt at a point along its own axis, which can be understood as... Figure 2C The line containing p in the middle and Figure 7A The angle between the lines containing p' and the line containing p'.

[0162] In some examples, a larger angular deviation range for the second connector 220 results in a larger tilt angle limit for the connector body 10. Conversely, a smaller angular deviation range for the second connector 220 results in a smaller tilt angle limit for the connector body 10.

[0163] Therefore, in some examples, the larger the taper configuration of the pagoda spring, the greater the limit of the tilt angle of the connector body 10.

[0164] In other examples, the smaller the taper of the pagoda spring, the smaller the limit of the tilt angle of the connector body 10.

[0165] According to the server 400 provided in the embodiments of this application: by introducing a first pagoda spring 51 and a second pagoda spring 52, and utilizing the structural characteristics of the pagoda springs to form a designed gap in the axial direction, the connector body 10 can be tilted at a certain point along its own axis, that is, the tilt angle of the first connector 100 can be floated. Thus, based on the radial and axial float of the connector body 10, the tilt angle float of the connector body 10 is introduced, realizing the angular deviation between the first connector 100 and the second connector 220, improving the fault tolerance and success rate of the first connector 100 in blind mating under complex working conditions. Furthermore, when the external force is removed, the elastic effect of the pagoda springs can enable the connector body 10 to return to the point where the first central axis and the second central axis coincide, thus ensuring that the connector body 10 can be stably in an aligned state.

[0166] Figure 7B yes Figure 2C The diagram shows the structure of the first connector in which the second pagoda spring is sleeved on the connector body.

[0167] Combination Figure 7B As shown, in some embodiments, the second pagoda spring 52 is closer to the first mating member 300 than the first pagoda spring 51. The second elastic force required to be provided by the second pagoda spring 52 can be determined as follows:

[0168] in: F2 is the second elastic force; W represents the radial force acting on the second pagoda spring; n is the axial dimension of the second pagoda spring; m is the radial force dimension of the second pagoda spring. The radial force dimension of the second pagoda spring can be half the difference between the diameter of the large end of the second pagoda spring and the diameter of the first part 15 of the connector body 10.

[0169] In some embodiments, the radial force W on the second pagoda spring can be the sum of the gravity of the second alignment block 60, the connector body 10, and the first mating member 300.

[0170] Accordingly, to ensure that the first pagoda spring 51 and the second pagoda spring 52 can abut against the protrusion 22 and the corresponding stop, the second elastic force required by the first pagoda spring 51 is configured to be greater than the second elastic force required by the second pagoda spring 52, denoted as F3. Thus, when the first joint 100 is in its initial position, under the action of the difference between the second elastic force of the first pagoda spring 51 and the second elastic force of the second pagoda spring 52, the first alignment block 20 and the second alignment block 60 are effectively engaged. Simultaneously, by controlling the compression distance of the first pagoda spring 51, it is possible to prevent the second alignment block 60 from separating from the first alignment block 20 during the floating process.

[0171] Furthermore, the first pagoda spring 51 and the second pagoda spring 52 can be selected based on the second elastic force required by the first pagoda spring 51 and the second pagoda spring 52, that is, the size parameters of the two can be determined.

[0172] Reference Figure 2B and Figure 2C As shown, in some embodiments, the first connector 100 further includes a throttle valve 80 with a fluid chamber 81 through which coolant flows. The throttle valve 80 is installed within the receiving chamber 101, with one end connected to the first end 11 and the other end connected to the second end 12, allowing coolant to flow through the fluid chamber 81 into the heat dissipation device. Thus, the flow rate of coolant through the receiving chamber 101 can be adjusted by the throttle valve 80. Furthermore, by fully utilizing the axial dimension of the connector body 10 and accommodating the placement of the throttle valve 80 within the connector body 10, the liquid cooling inlet / outlet and floating functions between the server 400 and the rack 200 are unified, allowing for better control of coolant flow and improved space utilization.

[0173] When the throttle valve 80 is installed in the accommodating cavity 101, the radial force W on the second pagoda spring 52 can be determined as the sum of the weights of the second alignment block 60, the connector body 10, the throttle valve 80, and the first docking member 300.

[0174] In some implementations, the second spring force required to be provided by the second pagoda spring 52 can be configured as the theoretical value F2 obtained from the above calculation formula. A reserve value greater than 1 is provided to counteract the decrease in elasticity of the second pagoda spring 52 during prolonged use, thereby improving the long-term reliability of the second pagoda spring 52. In other words, the redundant elasticity design of the pagoda spring ensures the stability of the first connector 100 in the aligned state.

[0175] In some examples, if the theoretical value F2 obtained from the above calculation is a1, and the reserved value is m, then the second elastic force configuration required by the second pagoda spring 52 is a2 = a1. m. Where a1 and a2 are positive numbers, and m is a number greater than 1.

[0176] For example, m can be 1.2, 1.25 or other values. This application does not limit the specific value of m in the embodiments.

[0177] Accordingly, in some embodiments, the second elastic force required to be provided by the first pagoda spring 51 can be configured as F3 as determined in the above manner. A reserve value greater than 1 is provided to counteract the decrease in elasticity of the first pagoda spring 51 during long-term use, thereby improving the long-term reliability of the first pagoda spring 51.

[0178] Figure 8 This is a schematic diagram of the structure of the second alignment block in the first connector of the server provided in this application embodiment.

[0179] Reference Figure 2A and Figure 8 As shown, in some embodiments, the first connector 100 further includes a guide sleeve 61, which passes through the second alignment block 60 along the axial direction of the connector body 10, for engaging with the guide pin 223 of the second connector 220. Thus, during the insertion of the server 400 into the rack 200 along the loading direction, the guide pin 223 on the rack 200 is inserted first into the guide sleeve 61, which moves with the server 400. Through the cooperation of the guide pin 223 and the guide sleeve 61, the alignment of the first docking member 300 and the second docking member 221 is completed before they contact each other, i.e., coarse positioning of the first docking member 300 and the second docking member 221.

[0180] Reference Figure 5 As shown, in some embodiments, the first alignment block 20 is provided with a notch 23, and the guide sleeve 61 passes through the second alignment block 60 and extends to the notch 23 to increase the axial dimension of the guide sleeve 61, thereby increasing the docking space when aligned with the guide pin 223, thereby improving the alignment effect of the first connector 100 and the second connector 220.

[0181] In some examples, the first connector 100 includes a guide sleeve 61 that passes through the second alignment block 60 and extends to a notch 23. The notch 23 corresponds to the position of the guide sleeve 61.

[0182] Reference Figure 2A and Figure 8 As shown, in other examples, the first connector 100 includes two guide sleeves 61, which are spaced apart and pass through the second alignment block 60 and extend to the notch 23. The notch 23 corresponds to the position of the guide sleeves 61, which can improve the coarse positioning effect.

[0183] In some examples, two guide sleeves 61 are arranged circumferentially on the second alignment block 60. In this case, the two guide sleeves 61 form a triangular layout with the connector body 10 in the radial direction of the connector body 10. That is, the two guide sleeves 61 and the connector body 10 respectively serve as the three corners of the triangle. This three-point positioning can effectively resist the circumferential torsion when the first connector 100 and the second connector 220 are connected, and the stable and compact layout can improve its compatibility design capability within the unit standard height space of the server 400.

[0184] Reference Figure 8 As shown, in some embodiments, the second alignment block 60 is provided with a guide hole 62 extending axially along the connector body 10, and the guide sleeve 61 passes through the guide hole 62 to connect with the second alignment block 60.

[0185] In some examples, the guide sleeve 61 may be interference-fitted with the guide hole 62.

[0186] In other examples, the guide sleeve 61 is provided with a fifth external thread for connecting to the second alignment block 60, and the guide hole 62 is provided with a fifth internal thread (not shown). The guide sleeve 61 and the second alignment block 60 are fixedly connected by the fifth external thread and the fifth internal thread.

[0187] Figure 9 This is a schematic diagram of the structure of the first mating part of the first connector in a server provided in an embodiment of this application.

[0188] Combination Figure 9 As shown in some examples, the first mating part 300 is provided with a sixth external thread 301 at one end for connecting with the connector body 10, and the inner wall of the first end 11 of the connector body 10 is provided with a sixth internal thread. The connection between the first mating part 300 and the connector body 10 is realized through the cooperation of the sixth internal thread and the sixth external thread 301.

[0189] Reference Figure 2DAs shown, in some embodiments, in the axial direction of the connector body 10, the connector body 10 sequentially includes a third part 17, a second part 16, a first part 15, and a fourth part 18 along the direction from the first end 11 to the second end 12.

[0190] The third part 17 is connected to the first mating part 300. Accordingly, a sixth internal thread may be provided on the third part 17.

[0191] In some application scenarios, when the first connector 100 of the server 400 mates with the second connector 220 on the rack 200, the server 400 is inserted into the rack 200. Through the cooperation of the guide pin 223 and the guide sleeve 61 on the rack 200, the first connector 100 and the second connector 220 are aligned before they mate (which can also be understood as the stage when the axial elastic element 40 has pre-pressure and has not been further compressed), thus achieving coarse positioning of the insertion. Correspondingly, the axial movement of the connector body 10 is achieved through the axial elastic element 40 and the first alignment block 20, and the radial movement of the connector body 10 is achieved through the first gap d1, thus achieving fine positioning between the first connector 100 and the second connector 220. In other words, the floating capability of the first connector 100 is used to absorb the manufacturing or assembly tolerances of the second connector 220.

[0192] In some embodiments, the second alignment block 60 is fixedly connected to the second portion 16 of the connector body 10 so that the connector body 10 and the second alignment block 60 can float together along the radial direction of the connector body 10.

[0193] According to the server 400 provided in the embodiments of this application: by fixing the second alignment block 60 to the connector body 10, the second alignment block 60 and the connector body 10 are combined into an integral floating unit. When there is a radial deviation between the first connector 100 and the second connector 220, the radial force acting on the connector body 10 will be directly transmitted to the second alignment block 60, so that the integral floating unit can move radially in a coordinated manner under the constraint of the first gap d1. This improves the force distribution of radial movement, and enhances the stability and structural integrity of the radial movement process through the larger contact and guiding area between the second alignment block 60 and the first alignment block 20.

[0194] In some embodiments, a second radial gap is also provided between the second alignment block 60 and the mounting base 30, and the second gap is equal to the first gap d1 between the first alignment block 20 and the connector body 10. This avoids interference between the second alignment block 60 and the mounting base 30 when the second alignment block 60 moves radially along with the connector body 10, thus improving structural stability.

[0195] Figure 10This is a schematic diagram of the connection cross section between the first alignment block and the second alignment block of the first connector in a server provided in an embodiment of this application.

[0196] Reference Figure 10 As shown, in some embodiments, the first connector 100 further includes an elastic block 71 and a centering pin 72. It is elastically connected to the first alignment block 20 or the second alignment block 60 (see...). Figure 10 (As shown). The centering pin 72 is axially connected to the first alignment block 20 and the second alignment block 60 along the joint body 10. The centering pin 72 is partially inserted into the elastic block 71 so that the second alignment block 60 can rotate radially relative to the first alignment block 20, driving the joint body 10 to rotate along its own axis to accommodate the rotational deviation of the second joint 220.

[0197] Here, the rotational deviation of the second connector 220 can be understood as: the angular difference between its theoretical radial angular position and its actual radial angular position caused by manufacturing or assembly errors that cause the second connector 220 to rotate along its own axis.

[0198] According to the server 400 provided in the embodiments of this application, radial rotation between the first alignment block 20 and the second alignment block 60 is achieved by introducing an elastic block 71 and a centering pin 72. The second alignment block 60 is axially connected to the first alignment block 20 via the centering pin 72, with the centering pin 72 partially inserted into the elastic block 71. When there is a rotational deviation between the second connector 220 and the first connector 100, i.e., an angular difference between the actual and theoretical positions of the two guide pins 223 relative to the radial center of the second alignment block 60, the second alignment block 60 can adaptively rotate along its own axis relative to the first alignment block 20 under the action of the elastic block 71 and the centering pin 72. During this process, the elastic block 71 surrounding the centering pin 72, through its own elastic deformation, provides the necessary flexible space and buffer for this relative floating, and continuously provides elastic restoring force to return the second alignment block 60 to its initial position (i.e., without the state of adapting to the rotation of the second connector 220 along its own axis), ensuring the reset capability of the first connector 100 and enhancing the reliability of the blind insertion operation.

[0199] In some embodiments, the second alignment block 60 is provided with a receiving groove (not shown) for receiving the elastic block 71.

[0200] In other embodiments, the first alignment block 20 is provided with a receiving groove (not shown) for receiving the elastic block 71.

[0201] In some examples, the first alignment block 20 is provided with a straightening hole extending axially along the connector body 10 for connection with the straightening pin 72. In this case, the elastic block 71 is accommodated in the receiving groove of the second alignment block 60 for connection with the second alignment block 60.

[0202] In other examples, the second alignment block 60 has a straightening hole extending axially along the connector body 10 for connection with the straightening pin 72. In this case, the elastic block 71 is accommodated in the receiving groove of the first alignment block 20 for connection with the first alignment block 20.

[0203] In some embodiments, the first connector 100 includes an elastic block 71 and a centering pin 72. In this case, the elasticity of the elastic block 71 is used to make the second alignment block 60 float relative to the first alignment block 20.

[0204] In other embodiments, the first connector 100 includes at least two elastic blocks 71 and at least two centering pins 72, with the number of elastic blocks 71 and centering pins 72 being equal. At least two elastic blocks 71 are spaced apart circumferentially along the connector body 10; at least two centering pins 72 are spaced apart circumferentially along the connector body 10 and are partially inserted into the corresponding elastic blocks 71. Thus, by setting the elastic blocks 71 and centering pins 72 to at least two equal sets arranged circumferentially along the connector body 10, when the second alignment block 60 floats relative to the first alignment block 20, the circumferentially distributed multiple elastic blocks 71, through coordinated deformation, provide the second alignment block 60 with balanced elastic restoring force from multiple directions, enabling it to automatically return to its initial position after any radial offset, thereby enhancing the reliability of the blind mating of the first connector 100.

[0205] Furthermore, by utilizing the elasticity and thickness (the degree of deformation of the elastic block 71) of the elastic block 71 and the design gap of the pagoda spring, when the elastic block 71 is compressed, the second alignment block 60 can drive the connector body 10 to rotate around the axis of the connector body 10; when the external force is removed, the first connector 100 can be subjected to the elastic force of the elastic block 71, so that the first connector 100 returns to the initial position, thereby realizing the function of rotating the first connector 100 along its own axis to adapt to the rotational deviation of the second connector 220.

[0207] Reference Figure 11 In the example shown, the first connector 100 includes three elastic blocks 71, which are spaced apart circumferentially from the second alignment block 60. Correspondingly, the second alignment block 60 is provided with three receiving grooves (not shown) spaced apart circumferentially from the connector body 10, which are used to receive the elastic blocks 71 respectively.

In this case, the elastic block 71 is accommodated in the receiving groove of the second alignment block 60 to connect with the second alignment block 60.

[0212] Figure 13 This is a schematic diagram of the structure of the straightening pin of the first connector in a server provided in an embodiment of this application.

[0213] Reference Figure 13 As shown, in some embodiments, the centering pin 72 has a first end 721 and a second end 722 along its own axial direction. The first end 721 is used for insertion into the elastic block 71, and the second end 722 is used for elastic connection to the first alignment block 20 (see...).

[0215] In some examples, the diameter of the insertion hole 711 is smaller than the diameter of the first end 721 of the centralizing pin 72, so that the first end 721 of the centralizing pin 72 is interference-fitted into the insertion hole 711.
