Description
TECHNICAL FIELD
[0001] The present application relates to the field of liquid cooling blind plug-in systems, and in particular to a floating mechanism for blind plug-in connection and a liquid cooling blind plug-in connection system. BACKGROUND
[0002] With the development of high-density server liquid cooling technology, the automatic connection of cooling liquid paths using blind plug-in connectors has become a mainstream solution. Generally, during the process of pushing the server chassis along the slide rail into the cabinet, the blind plug-in male head at the end of the chassis needs to be precisely connected with the female head of the liquid distributor fixed on the back plate of the cabinet to complete the liquid taking process. However, the internal structure of the whole cabinet system is complex, with numerous components, resulting in a large cumulative tolerance in the assembly link from the chassis to the liquid distributor. The limited floating amount provided by the traditional blind plug-in connector often cannot effectively compensate for this macroscopic tolerance, easily leading to the failure of individual position connector insertion and causing the risk of cooling liquid leakage.
[0003] To address the above tolerance problem, the prior art usually adopts a scheme of overall floating of the entire connector module with the mounting bracket. Although this way increases the floating range to some extent, it also brings new defects: first, overall floating results in large mass of moving parts and large required movement space, which is contrary to the design trend of server compactness and high density. Second, such a scheme usually relies on a single guide pin for rough positioning, and due to the need to meet the demand for large floating amount, the fitting gap between the guide pin and the hole is large, which makes it unable to effectively constrain the slight deflection of the connector due to uneven force during the connection process. The slight angular deflection of the connector significantly increases the insertion force, leading to seal ring wear or even insertion failure. Therefore, the prior art cannot simultaneously meet the contradictory demands of large floating amount compensation and high-precision deflection control in limited space, which has become a key technical bottleneck for improving the reliability of liquid cooling system blind plug-in connection.
[0004] Therefore, it is necessary to propose a floating mechanism scheme for blind plug-in connection to solve the above technical problems. SUMMARY
[0005] The present application aims to provide a floating mechanism for blind plug-in connection and a liquid cooling blind plug-in connection system to solve the problem that the existing blind plug-in connector cannot simultaneously meet the dual demands of compensating for macroscopic assembly tolerance and suppressing microscopic angular deflection in limited space due to the mutual restriction of floating amount and deflection control capability, resulting in insertion failure.
[0006] To achieve the above-mentioned purpose, the present application is implemented as follows:
[0007] In a first aspect, the present application provides a floating mechanism for blind plug-in connection, comprising:
[0008] a mounting fixed seat fixedly connected with the chassis;
[0009] A joint mounting seat for mounting a blind-mate joint;
[0010] A floating connection assembly connected between the mounting fixture and the joint mounting seat, configured to allow the joint mounting seat to float in a radial plane relative to the mounting fixture;
[0011] An independent guiding mechanism arranged between the mounting fixture and the joint mounting seat, and spatially separated from the floating connection assembly; the independent guiding mechanism is configured to constrain the joint mounting seat from deflecting around an axial direction when the joint mounting seat floats radially.
[0012] A second aspect. A liquid-cooled blind-mate connection system is provided, comprising:
[0013] A fixed-side unit comprising a blind-mate liquid distributor and a blind-mate female head mounted thereon;
[0014] A mobile-side unit comprising a server chassis; and,
[0015] The floating mechanism as described in the first aspect is mounted on the chassis.
[0016] A third aspect, the present application also provides a computer-readable storage medium, the computer-readable storage medium stores a computer program, the computer program is executed by a processor to implement the steps of the method as described in the first aspect.
[0017] The present application has the following beneficial effects:
[0018] The floating mechanism for blind-mate connection of the present application successfully solves the technical problem of mutual restriction between floating amount and docking precision in the field of blind-mate connection through the design of "functional decoupling". Specifically, the floating connection assembly deals with macroscopic positional deviation, and is optimized to allow the joint mounting seat to produce a large enough displacement in a radial plane, thereby efficiently absorbing the complex assembly cumulative tolerance of the cabinet system, providing sufficient floating amount, and ensuring that the joint can initially enter the range of insertion. At the same time, the independent guiding mechanism, which is spatially separated, plays the role of "precision guardian". It does not interfere with the normal radial floating of the joint mounting seat, but is used to constrain the harmful deflection around the axial direction generated during the floating process. This precise angle control ensures that the docking axis of the blind-mate joint can maintain a very high parallelism with the female head throughout the entire insertion process.
[0019] Thus, the split architecture realizes the synergistic effect of "large floating and high-precision guiding". The floating connection assembly ensures the "alignment" capability of the joint, and the independent guiding mechanism ensures the "alignment" accuracy after alignment. Both of them play their respective roles and cooperate with each other, so that the application can compensate for larger tolerances while realizing more reliable and smooth blind insertion connection than the traditional overall floating scheme, fundamentally eliminating the faults such as the surge of insertion and extraction force, interface wear and failure of insertion caused by excessive deflection angle, and significantly improving the deployment success rate and long-term reliability of the system in harsh industrial environments. Thus, the problem between the need for large floating amount compensation due to assembly tolerance and the need for high-precision axis alignment to prevent deflection failure when docking is solved.

[0032] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent changes or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.
[0033] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0034] Example One:
[0035] Combination Figures 1 to 8 This embodiment provides a floating mechanism 100 for blind mating connections, comprising: a mounting base 10 fixedly connected to a chassis; a connector mounting base 20 for mounting blind mating connectors (i.e., blind mating male connectors 21); a floating connection assembly connected between the mounting base 10 and the connector mounting base 20, configured to allow the connector mounting base 20 to float relative to the mounting base 10 in a radial plane (XY plane); and an independent guide mechanism disposed between the mounting base 10 and the connector mounting base 20, and spatially separate from the floating connection assembly; the independent guide mechanism is configured to constrain the axial deflection of the connector mounting base 20 when it floats radially.
[0036] It should be noted that "rotation about the axial direction" refers to the fact that when the connector mounting base 20 moves in the radial plane XY, it is not a pure translation, but may rotate slightly around the axis AA' (Z-axis) perpendicular to the plane. This rotation is the direct cause of jamming or failure of the blind-fit connector during mating.
[0037] The independent guiding mechanism includes a guide hole 31 and a deflection guide pin 32 that cooperate with each other. The guide hole 31 is provided on the floating limit base 40, and the deflection guide pin 32 is fixed on the mounting base 10.
[0038] Through the precise fit between the hole (guide hole 31) and the pin (deflection guide pin 32), the harmful rotational torque is converted into a reaction force on the contact surface, thereby forming an effective reaction torque. This suppresses and corrects the deflection angle in real time, ensuring that the axis AA' (axis AA' is parallel to the Z-axis) of the blind-fit connector maintains the correct guidance throughout the entire mating process, fundamentally solving the problem of mating failure caused by angular deviation.
[0039] The floating connection assembly includes an axial elastic element that provides axial support to the connector mounting base 20 and allows it to float axially. Specifically, the axial elastic element is a spring 50, which is sleeved on the screw 51. When the blind-mate connector (i.e., the blind-mate male 21) is subjected to contact pressure from the blind-mate female 91 in the axial direction, the spring 50 is compressed, allowing the connector mounting base 20 and the floating limit base 40 to retract slightly along the axial direction of the screw 51. This floating stroke effectively absorbs the assembly tolerances and mating impacts in the axial dimension. At the same time, the continuous reverse support force provided by the spring 50 ensures that the male and female connectors maintain stable and tight contact after mating, thus ensuring both the smoothness of the mating process and the reliability of the seal after connection.
[0040] One end of the screw 51 is threadedly connected to the floating limiting base 40, while the other end (free end) of the screw 51 passes through the corresponding through hole 11 and washer screw 60 on the mounting base 10. The diameter of the screw 51 is slightly smaller than the diameter of the through hole 11 on the mounting base 10, with a precise radial clearance δ between them. By rotating the washer screw 60, the initial compression of the spring 50 can be changed, thereby precisely adjusting the preload of the axial floating mechanism and enabling the mechanism to adapt to joints with different insertion and extraction forces. Simultaneously, the radial clearance δ between the screw 51 and the through hole 11 allows the entire floating assembly to undergo a small range of initial radial guidance during the first guidance (the entire floating mechanism engages with the distributor guide pin), correcting larger deviations in advance and making subsequent docking smoother. This structure integrates the adjustability of the axial floating force with the initial radial guidance function.
[0041] The working principle of the floating mechanism 100 in this embodiment mainly lies in decoupling the two major functions of "floating" and "guiding," with two spatially separate components each performing their respective functions and working collaboratively. Firstly, when there is a radial positional deviation between the blind-mate male connector 21 and the blind-mate female connector 91 due to system assembly tolerances, the lateral force generated during the mating process will act on the connector mounting base 20. Combined with... Figure 1 , Figures 8 to 10To explain, at this point, the floating connection assembly connecting the mounting base 10 and the connector mounting base 20 begins to function. It allows and guides the connector mounting base 20 to carry the male connector in a radial plane (XY plane) for translational floating (i.e., radial floating), thereby passively adapting to and compensating for the positional deviation. This ensures the male connector can smoothly enter the female connector's capture range; this process is purely to provide the necessary floating amount to absorb macroscopic positional errors. Simultaneously, the clamping force generated by the axial contact of the male and female connectors compresses axial elastic elements such as springs, allowing the connector mounting base 20 to produce a small axial backward displacement, i.e., axial floating, to buffer the docking impact and compensate for axial dimensional chain errors. These two floating mechanisms work together to ensure that even with multidimensional errors, the connector can still achieve a smooth and reliable connection through adaptive adjustment.
[0042] Throughout the radial floating process of the connector mount 20, the independently configured guide mechanism synchronously activates its core function (restraining harmful rotation around the axis). Due to uneven force distribution, the floating connector mount 20 is prone to generating a deflection torque around the axial direction (Z-axis), which is the main cause of mating failure. The independent guide mechanism, through its precisely matched components (such as interacting guide holes and guide pins), provides a counter-torque in the opposite direction the moment it detects the deflection tendency. This counter-torque effectively suppresses the torsion of the connector mount 20, firmly restraining its rotational freedom around the Z-axis, ensuring that despite the significant radial floating of the male connector, its mating axis always maintains a very high degree of parallelism with the female connector axis, ultimately achieving precise and reliable blind mating connections in complex tolerance environments.
[0043] In the above embodiments, the floating connection assembly further includes a radial floating structure, which includes a floating limiting base 40 and a floating limiting pressure block 41. The connector mounting seat 20 is engaged between the floating limiting base 40 and the floating limiting pressure block 41, and a gasket 70 is provided between them. The gasket 70 enables low-friction floating in the radial plane, thereby forming a sliding pair that allows the connector mounting seat 20 to slide in the radial plane. The gasket 70 is located inside the radial floating structure, between the sliding contact surfaces of the connector mounting seat 20 and the floating limiting base 40 (or the floating limiting pressure block 41). Specifically, the gasket 70 can be a graphite nylon gasket.
[0044] It should be understood that the radial floating structure forms a sliding "sandwich" structure by locking the connector mounting base 20 between the floating limiting base 40 and the floating limiting pressure block 41; the graphite nylon gasket in between utilizes its excellent self-lubricating properties to significantly reduce the sliding friction resistance between the connector mounting base 20 and the adjacent fixed components when the radial floating occurs. This allows the male connector to slide smoothly to the alignment position with minimal resistance when subjected to the lateral force of the female connector. Thus, while achieving a wide range of radial floating compensation, it avoids jamming or poor movement caused by excessive friction, ensuring a smooth mating process.
[0045] The floating connection assembly also includes a centering mechanism configured to maintain the connector mounting base 20 in its initial centered position when not mated. Specifically, the centering mechanism consists of multiple circumferentially arranged spring plungers 80, whose pins continuously abut against the sides of the connector mounting base 20 or the floating limiting base 40. This configuration ensures that the circumferentially distributed spring plungers 80 continuously apply uniform radial preload to the sides of the connector mounting base 20 or the floating limiting base 40 through their pins. When not mated, these uniformly distributed spring forces balance each other, dynamically stabilizing the floating component in a preset initial centered position. This not only prevents random drift of the component during transportation or vibration but also ensures that the male connector approaches the female connector in the correct initial posture at the start of mating, greatly improving the success rate of the first mating and the guiding reliability of the entire blind mating process.
[0046] Furthermore, the mounting base 10 of the floating mechanism 100 is connected and fixed to the studs on the bottom shell of the chassis by screws, and blind plugs 21 and hoses 22 are respectively installed on the left and right sides of the mounting base 10.
[0047] A set of first guide holes 42 are provided on the floating limit base 40. A set of first-stage guide pins 92, corresponding to the first guide holes 42, are fixedly installed on the panel 90 of the blind-plug dispenser, which is fixed to the back panel of the cabinet and faces the chassis. The length of the first-stage guide pins 92 is designed such that, during the chassis insertion process, they contact the blind-plug male connector 21 on the floating mechanism with the blind-plug female connector 91 on the dispenser 93 before the blind-plug male connector 21 on the floating mechanism. The independent guiding mechanism inside the floating mechanism (i.e., the second-stage guiding mechanism, consisting of the deflection guide pin 32 and the guide hole 31) is responsible for guiding the final precision connection of the connector after the first guiding is completed.
[0048] The working process of the floating mechanism in this embodiment is as follows:
[0049] 1. Initial Approach and First Guidance (Coarse Positioning): The operator begins to push the server chassis into the rack along the slide rails. The mounting bracket 10 on the chassis and its entire floating mechanism move forward accordingly. At this time, the blind male connector 21 has not yet made contact with the blind female connector 91 on the dispenser.
[0050] The first-stage guide pin 92, fixed on the blind-insertion dispenser, is designed to be inserted into the floating mechanism guide hole 31 on the floating mechanism floating limit base 40 before all blind-insertion connectors.
[0051] This initial guidance (coarse positioning) corrected for the macroscopic assembly tolerances accumulated by components such as the chassis and slide rails. It roughly guided the entire floating mechanism and its male connectors to the front of the distributor's female connector cluster, ensuring that subsequent male connectors could enter the female connectors' "capture range" and avoiding direct rigid impact. The floating mechanism may therefore experience a small, overall offset.
[0052] 2. Male and female connector contact and floating start: As the chassis continues to be pushed in, the end of the blind male connector 21 begins to contact the tapered guide port of the blind female connector.
[0053] (1) Axial floating start: The blind male connector 21 is subjected to the axial reaction force of the blind female connector 91, which compresses the spring 50, causing the connector mounting base 20 and the floating limit base 40 and other components to generate a small backward displacement along the screw 51, absorbing axial impact and tolerance.
[0054] (2) Radial floating standby: Due to unavoidable radial position deviation, the male head will be subjected to lateral force from the female mouth wall.
[0055] 3. Radial floating and deflection control (precision positioning): Under the continuous action of lateral force, docking enters the most critical precision guidance stage.
[0056] (1) Radial floating: Lateral force pushes the connector mounting base 20, causing it to overcome the weak holding force of the spring plunger 80 and slide smoothly radially in the interlayer formed by the floating limit base 40 and the floating limit pressure block, thanks to the lubrication of the graphite nylon gasket 70. This compensates for the remaining radial tolerance, allowing the male connector to "follow" the center movement of the female connector.
[0057] (2) Deflection control (core): During radial sliding, any uneven force will attempt to make the connector mounting base 20 carry the male head to rotate around the axis. At this time, the independent guide mechanism immediately intervenes: the deflection guide pin 32 fixed on the moving part contacts the inner wall of the guide hole 31 fixed on the mounting base 10, generating a strong counter torque that instantly suppresses and corrects this harmful deflection tendency.
[0058] This is the second guidance (precision positioning), which ensures that the central axis AA' of the blind male connector 21 always maintains a very high degree of parallelism with the axis of the female connector throughout the entire floating process, solving the core problem that leads to the failure of the mating (i.e., angular deflection).
[0059] 4. Final insertion and stable connection: Under the combined guidance of radial floating and deflection control, the male head successfully slides into the center of the female head and overcomes the resistance of the sealing ring, finally inserting to the bottom to form a complete sealing flow channel.
[0060] (1) Axial positioning: When the blind male head 21 is fully inserted, the preload of the spring 50 continues to act to ensure that the male and female heads maintain stable and tight contact and ensure the reliability of the seal.
[0061] (2) Radial stability: After the external thrust is removed, under the centering action of the spring plunger 80, the connector mounting seat 20 tends to return to the center position, but will be held in the final position by the mated connector. In this way, this series of continuous and coordinated actions enables the floating mechanism 100 to intelligently adapt to complex environmental tolerances, transforming the uncertain "blind insertion" into a highly reliable "precise insertion".
[0062] Example Two:
[0063] like Figure 7 As shown, this embodiment provides a liquid-cooled blind-plug connection system, including: a fixed-side unit, which includes a blind-plug distributor and a blind-plug female connector 91 mounted thereon (the fixed-side unit internally includes a liquid distribution manifold, and its panel integrates multiple blind-plug female connectors in an array and an optional first-stage guide pin 92, the first-stage guide pin 92 being fixed to the panel 90 of the blind-plug distributor facing the chassis, opposite to the position of the first guide hole 42 opened on the floating limit base 40); and a mobile-side unit, which includes a server chassis and a floating mechanism 100 mounted on the chassis (specifically, one or more floating mechanisms are independently installed on each chassis corresponding to the position of the distributor female connector array). A blind-plug male connector 21 is mounted on the connector mounting base 20 of each floating mechanism. The floating mechanism 100 includes: a mounting base 10 fixedly connected to the chassis; a connector mounting base 20 for mounting a blind male connector 21 that mates with a blind female connector; a floating connection assembly connected between the mounting base 10 and the connector mounting base 20, configured to allow the connector mounting base 20 to float radially relative to the mounting base 10; and an independent guide mechanism disposed between the mounting base 10 and the connector mounting base 20, and spatially separate from the floating connection assembly. The independent guide mechanism is configured to constrain the axial deflection of the connector mounting base 20 when it floats radially. The blind male connector dispenser is provided with a first guide pin 92, and the mounting base 10 is provided with a first guide hole 42 that mates with the first guide pin 92. The first guide pin is configured to mate with the first guide hole 42 before the blind male connector 21 contacts the blind female connector.
[0064] When all server chassis are simultaneously pushed into the rack, all floating mechanisms on each chassis activate simultaneously, causing all blind-plug male connectors 21 on each chassis to complete a one-time blind-plug connection with the corresponding blind-plug female connector cluster on the blind-plug distributor. This structure simplifies complex multi-channel liquid cooling connections into a single "blind-plug" action. The blind-plug distributor acts as a centralized liquid distribution and management center, while each server chassis is an independent terminal with adaptive docking capabilities. This system achieves high-density, modular, and rapid deployment of liquid cooling connections, making it particularly suitable for rack-mounted liquid-cooled servers.
[0065] Furthermore, a filter can be installed in series at the fluid inlet of the blind-type male connector 21. Specifically, the filter outlet is connected to the inlet of the blind-type male connector 21 via a flexible or rigid pipe, and the filter inlet is connected to the liquid cooling piping inside the chassis. A bypass valve can also be integrated into the filter housing, which opens when the filter element becomes clogged, causing the inlet-outlet pressure difference to exceed a set value. Before entering the precision blind-type male connector 21, the coolant flows through a cartridge filter, where impurities are intercepted by the filter element. When maintenance is required, simply unscrew the old filter and replace it with a new one; there is no need to disassemble the blind-type connector or main piping. The bypass valve provides safety protection, preventing fluid interruption and system overheating due to complete filter element clogging. This structure greatly improves the reliability and maintainability of the system.
[0066] The liquid-cooled blind mating connection system provided in this embodiment combines a floating mechanism 100 with radial floating and deflection control functions with a liquid distributor unit that integrates a pilot docking structure to construct a two-stage guided collaborative working system. This effectively solves the technical problem that the macroscopic tolerances accumulated by the assembly of numerous components in the whole rack liquid-cooled server are too large, and the single floating amount of the existing blind mating connector cannot fully compensate for the tolerances, nor can it simultaneously suppress the harmful deflection generated during the mating process, thus causing blind mating failure of individual units.
[0067] In existing liquid-cooled server systems, when a blind-plug connector or filter needs replacement, the entire rack's coolant typically needs to be drained, leading to prolonged system downtime and extremely high maintenance costs. Therefore, this embodiment provides a solution enabling online maintenance of a single channel. This embodiment provides a blind-plug module that can be quickly replaced online, comprising: a module housing connected to the server chassis via a floating mechanism; a blind-plug male connector 21 installed inside the module housing; a cartridge filter connected to the inlet end of the blind-plug male connector via a quick-change connector; and a maintenance valve located at the coolant inlet of the module housing, configured to automatically cut off the coolant path when the module is separated from the chassis. The module housing is equipped with a maintenance locking mechanism; when this mechanism is unlocked, the entire module, along with the blind-plug male connector and filter, can be removed from the connector mounting base of the floating mechanism. The maintenance valve prevents coolant leakage from the chassis side. With this configuration, this embodiment integrates the concept of rapid maintenance into a high-precision blind insertion system. Through the combined design of "maintenance valve + quick-change connector + maintenance latch", it realizes online isolation and replacement of a single blind insertion channel, thereby solving the industry pain point of "maintenance requires downtime" in liquid-cooled data centers and significantly improving the maintainability and availability of the system.
[0068] Furthermore, servers vibrate during operation, and changes in coolant temperature cause thermal expansion and contraction in the piping. These dynamic factors lead to continuous dynamic stress on the blind-fit joints, affecting sealing reliability and potentially causing leaks with long-term use. This embodiment also provides an adaptive sealing blind-fit system resistant to vibration and thermal deformation, including the floating mechanism described in Embodiment 1; a dynamic sealing assembly including a main sealing ring and an auxiliary compensating sealing ring; a multi-stage buffer structure including an axial buffer pad disposed between the floating limit base 40 and the mounting base 10, and an elastic damping sheet disposed on the radial floating surface of the joint mounting base 20; and a thermal compensation mechanism using a combination of materials with different coefficients of thermal expansion to compensate for displacement of the floating connection assembly when the temperature changes. The multi-stage buffer structure is configured to absorb mechanical vibration during operation, and the thermal compensation mechanism is configured to compensate for thermal deformation of the piping system. With this configuration, this embodiment provides comprehensive dynamic protection through the synergistic design of "multi-stage buffering + thermal compensation + dynamic sealing," significantly improving the sealing reliability and service life of the blind-fit joints during long-term operation, and solving the technical bottleneck of liquid cooling systems from "usable" to "easy to use."
[0069] It should be noted that the scheme or principle involved in the liquid-cooled blind plug connection system of this embodiment is the same as that of Embodiment 1, and the same or similar contents will not be described in detail.
[0070] Example Three:
[0071] like Figure 11 As shown, this embodiment provides a docking control method for liquid-cooled blind mating connections, including:
[0072] Step 1101. Move the floating mechanism installed on the server chassis toward the female head fixed on the dispenser.
[0073] Step 1102. First guiding step: By using the cooperation between the first guide pin set on the dispenser and the first guide hole set on the floating mechanism, the floating mechanism is roughly positioned before the blind insertion male and female heads come into contact.
[0074] Step 1103. Second guiding step: After the blind male connector contacts the female connector, the axial deflection generated by the blind male connector during the radial floating process is constrained by an independent guiding mechanism set inside the floating mechanism.
[0075] In step 1102, the floating mechanism allows the connector mounting base carrying the blind male connector to float in the radial plane through its internal floating connection assembly to compensate for the radial positional deviation between the male and female connectors.
[0076] This embodiment of the liquid-cooled blind mating connection control method effectively solves the technical problem in existing blind mating processes where the one-time guidance cannot simultaneously address macroscopic tolerance compensation and microscopic deflection control, leading to insertion obstruction, accelerated wear, or complete failure of the joint due to excessive axial deviation at the moment of contact. This method first eliminates system-level macroscopic assembly errors before the male and female joints contact using the first guidance step, creating initial conditions for precision mating. Then, in the second guidance step, while allowing radial floating of the joint to compensate for residual positional deviations, it precisely suppresses its axial deflection, thereby achieving one-time success and long-term reliable operation of blind mating connections under complex tolerance environments.
[0077] This invention also provides a terminal device, which may include a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the above-described functionality.
