Abstract
Description
Technical Field
[0001] This application relates to the field of liquid cooling technology, and more particularly to a splash-proof connector and server. Background Technology
[0002] To meet the demands of high computing power, servers are increasingly integrated with higher hardware levels, leading to a significant increase in power consumption. Traditional air cooling is no longer sufficient, and liquid cooling systems are widely used in servers due to their superior heat dissipation. Server liquid cooling systems require connectors to connect to an external coolant supply system to provide coolant and circulate it. However, existing connectors may leak coolant after a period of use. Furthermore, because of the pressure within the liquid cooling system, leaks can cause coolant to spray out from the connectors, potentially damaging core server components and causing hardware failure or server downtime. Summary of the Invention
[0003] To address at least one of the problems mentioned in the background art, this application provides a splash-proof connector and server that can prevent coolant from splashing and improve server protection.
[0004] To achieve the above objectives, this application provides the following technical solution:
[0005] This application provides a splash-proof connector for use in a server's liquid cooling system, comprising:
[0006] Mounting base;
[0007] The connector body is mounted on the mounting base. The first end is used to connect to the liquid cooling system, and the second end has a plug interface for connecting to the connector of the coolant supply system.
[0008] The housing has a mounting cavity, a first end of the housing is engaged with a mounting base, and a second end forms a first mounting port communicating with the mounting cavity. The second end of the connector body is located in the mounting cavity, and the insertion interface corresponds to the position of the first mounting port.
[0009] The shielding component is rotatably mounted in the mounting cavity;
[0010] The transmission mechanism has a first end that is movably inserted into the mounting cavity and elastically connected to the mounting base via a first elastic element, and a second end that extends outside the housing. The transmission mechanism and the shielding assembly are connected in a transmission manner so that when the connector and the plug are inserted, the second end of the transmission mechanism is pushed to retract into the mounting cavity, thereby causing the shielding assembly to move away from the position covering the plug. When the connector and the plug are separated, the transmission mechanism is reset under the elastic force of the first elastic element, so that the shielding assembly shields the plug.
[0011] As an optional implementation, the shielding assembly includes a baffle and mounting shafts connected to opposite sides of the baffle. The mounting shafts are rotatably connected to the inner wall of the mounting cavity, and a transmission mechanism is drivenly connected to the mounting shafts.
[0012] As an optional implementation, the transmission mechanism includes a rack and a gear meshing together. The gear is mounted on a mounting shaft. A first end of a first elastic element is connected to a mounting base, and a second end is connected to the first end of the rack. When the connector and the interface are plugged in, the second end of the rack is pushed to compress the first elastic element. The rack drives the gear and the mounting shaft to rotate, thereby rotating and removing the baffle from the position covering the interface. When the connector and the interface are separated, the rack returns to its original position under the elastic force of the first elastic element, causing the baffle to cover the interface.
[0013] As an optional implementation, the transmission mechanism also includes a linkage member. The first end of the linkage member is inserted into the mounting cavity, and the second end extends out of the housing. A rack is elastically connected to the linkage member. When the connector is inserted into the interface, the second end of the linkage member is pushed to drive the gear and the mounting shaft to rotate, thereby rotating and moving the baffle away from the position covering the interface.
[0014] As an optional implementation, the transmission mechanism further includes a second elastic element and a first guide post. The linkage has a blind hole and a groove. One side of the rack is connected to the first guide post. One end of the second elastic element is sleeved on the first guide post, and the other end passes through the blind hole. The second end of the rack is slidably connected to the groove.
[0015] As an optional implementation, a limiting part is formed on one side of the linkage member, and the second end of the housing has a second mounting port that communicates with the mounting cavity. The second end of the linkage member is configured to pass through the second mounting port from the first end of the housing. Before the connector is inserted into the interface, the limiting part abuts against the inner wall of the mounting cavity under the elastic force of the first elastic member and the second elastic member.
[0016] As an optional implementation, the mounting base has a receiving groove on the side facing the housing, and a second guide post is provided at the bottom of the receiving groove. The first end of the first elastic member is sleeved on the second guide post.
[0017] As an optional implementation, there are two connector bodies, which are used for the input and output of coolant to the liquid cooling system, respectively, and the housing has two first mounting ports corresponding to the positions of the connector bodies.
[0018] As an optional implementation, it also includes a pipe connector, with a first interface and a second interface respectively connected on opposite sides of the mounting base, a first end of the pipe connector connected to the first interface, a second end for connecting to the liquid cooling system, and a first end of the connector body connected to the second interface.
[0019] Secondly, this application also provides a server including the splash-proof connector described in the second aspect.
[0020] The splash-proof connector provided in this application allows the connector's connecting end to extend from the first mounting port of the housing into the mounting cavity and insert into the connector body's socket when the connector is connected to the socket. Simultaneously, the connector's housing pushes the second end of the transmission mechanism back into the mounting cavity. During this retraction, the transmission mechanism moves the shielding component away from its position covering the socket, thus creating space for connector insertion and ensuring smooth connection of the coolant passage. When the connector separates from the socket, the thrust of the connector body on the second end of the transmission mechanism disappears, and the transmission mechanism resets outward under the elastic force of the first elastic element. During this reset, the shielding component moves back to its position covering the socket. Because the connector is always located within the mounting cavity of the housing, and the shielding component can quickly block the connector when it is disengaged, even if there is pressure inside the liquid cooling system causing coolant to leak from the connector, the leaking coolant will be confined within the mounting cavity of the housing. At the same time, the shielding component directly blocks the connector, cutting off the path of coolant splashing outward from the source of the leak. This prevents coolant from splashing onto the core components inside the server, thus solving the problem that existing connectors may leak during use and cause coolant splashing due to internal pressure, which could lead to server hardware damage and operational interruption. This improves the server's protection effect. Attached Figure Description

[0035] To meet the demands of high computing power, servers are increasingly integrated with higher hardware levels, leading to a significant increase in power consumption. Traditional air cooling is no longer sufficient, and liquid cooling systems are widely used in servers due to their superior heat dissipation. Server liquid cooling systems require connectors to connect to an external coolant supply system to provide coolant and circulate it. However, existing connectors may leak coolant after a period of use. Furthermore, because of the pressure within the liquid cooling system, leaks can cause coolant to spray out from the connectors, potentially damaging core server components and causing hardware failure or server downtime.
[0036] In view of this, this application provides a splash-proof connector. The connector's connecting end can extend into the mounting cavity from the first mounting port of the housing and plug into the connector body's interface. The connector's housing synchronously pushes the second end of the transmission mechanism to retract into the mounting cavity, causing the shielding component to move away from the position covering the interface. When the connector separates from the interface, the transmission mechanism resets outward under the elastic force of the first elastic element. Since the interface is always within the mounting cavity of the housing, and the shielding component can quickly shield the interface when the connector separates, even if there is pressure inside the liquid cooling system causing coolant to leak from the interface, the leaked coolant will be confined within the housing's mounting cavity. At the same time, the shielding component directly blocks the interface, cutting off the coolant's path to splash outward from the source of leakage, preventing coolant from splashing onto the core components inside the server, and improving the server's protection effect.

[0038] You can refer to this. Figures 1 to 6 This application provides a splash-proof connector 100 for use in a server's liquid cooling system, comprising:
[0039] Mounting bracket 110;
[0040] The connector body 120 is disposed on the mounting base 110. The first end is used to connect to the liquid cooling system, and the second end has a plug interface 121 for connecting to the connector of the coolant supply system.
[0041] The housing 130 has a mounting cavity. The first end of the housing 130 is engaged with the mounting base 110, and the second end forms a first mounting port 131 that communicates with the mounting cavity. The second end of the connector body 120 is located in the mounting cavity, and the insertion interface 121 and the first mounting port 131 are positioned corresponding to each other.
[0042] The shielding assembly 140 is rotatably mounted in the mounting cavity;
[0043] The transmission mechanism 150 has a first end movably inserted into the mounting cavity and elastically connected to the mounting base 110 via a first elastic element 170. The second end extends outside the housing 130. The transmission mechanism 150 and the shielding assembly 140 are connected in a transmission manner so that when the connector and the insertion interface 121 are inserted, the second end of the transmission mechanism 150 is pushed to retract into the mounting cavity, thereby causing the shielding assembly 140 to move away from the position covering the insertion interface 121. When the connector and the insertion interface 121 are separated, the transmission mechanism 150 is reset under the elastic force of the first elastic element 170, so that the shielding assembly 140 shields the insertion interface 121.
[0044] The splash-proof connector 100 provided in this embodiment allows the connector end to extend from the first mounting port 131 of the housing 130 into the mounting cavity and insert into the connector body 120's connector interface 121 when the connector is connected to the interface 121. Simultaneously, the connector housing pushes the second end of the transmission mechanism 150 back into the mounting cavity. During this retraction, the transmission mechanism 150 moves the shielding component 140 away from its position covering the connector interface 121, thus creating space for connector insertion and ensuring smooth insertion into the connector interface 121 to connect the coolant passage. When the connector separates from the connector interface 121, the thrust of the connector body on the second end of the transmission mechanism 150 disappears, and the transmission mechanism 150 resets outward from the housing 130 under the elastic force of the first elastic element 170. During this reset, the shielding component 140 moves back to its position covering the connector interface 121.
[0045] Since the connector 121 is always located within the mounting cavity of the housing 130, and the shielding component 140 can quickly shield the connector 121 when the connector is separated, even if there is pressure inside the liquid cooling system causing coolant to leak from the connector 121, the leaked coolant will be confined within the mounting cavity of the housing 130. At the same time, the shielding component 140 directly blocks the connector 121, cutting off the path of coolant splashing outward from the source of leakage, thus preventing coolant from splashing onto the core components inside the server. This solves the problem that existing connectors may leak during use and cause coolant to splash due to internal pressure, which could lead to server hardware damage and operation interruption, thereby improving the server's protection effect.
[0046] In the above embodiments, the shielding assembly 140 may include a baffle 141 and a mounting shaft 142 connected to opposite sides of the baffle 141. The mounting shaft 142 is rotatably connected to the inner wall of the mounting cavity, and the transmission mechanism 150 is connected to the mounting shaft 142. When the connector is inserted into the interface 121 of the connector body 120, the second end of the transmission mechanism 150 is pushed to retract into the mounting cavity. The transmission mechanism 150 synchronously drives the mounting shaft 142 connected to it to rotate. When the mounting shaft 142 rotates, it drives the baffle 141 fixedly connected to it to rotate together, so that the baffle 141 rotates away from the initial position covering the interface 121, making room for the connector end to extend into the first mounting port 131 of the housing 130 and insert into the interface 121, ensuring that the connector can be smoothly inserted to achieve normal connection of the coolant passage. When the connector is separated from the interface 121, the transmission mechanism 150 is reset to the outside of the housing 130 under the elastic force of the first elastic element 170. During the reset process, the transmission mechanism 150 drives the mounting shaft 142 to rotate in the opposite direction, and the mounting shaft 142 drives the baffle 141 to rotate in the opposite direction synchronously, until the baffle 141 rotates back to the position covering the interface 121, completing the blocking reset.
[0047] The mounting shaft 142 is rotatably connected to the inner wall of the mounting cavity, providing stable mounting support and rotation trajectory for the rotation of the baffle 141. This ensures smooth and precise movement of the baffle 141, preventing jamming or misalignment that could lead to shielding failure. The baffle 141 is linked to the transmission mechanism 150 via the mounting shaft 142, allowing the rotation of the baffle 141 to precisely coordinate with the extension and retraction of the transmission mechanism 150. This enables the baffle 141 to automatically move away during connector insertion and automatically shield during separation, with rapid response. The baffle 141 can tightly cover the insertion interface 121. Combined with the enclosure effect of the mounting cavity of the housing 130, even if there is pressure inside the liquid cooling system or coolant leakage at the insertion interface 121, the baffle 141 can block the splash path of the leaking coolant from the source. At the same time, the mounting cavity can collect a small amount of leaked coolant, further preventing coolant from splashing onto the core components of the server.
[0048] In the above embodiments, the transmission mechanism 150 may include a rack 151 and a gear 152, which mesh. The gear 152 is mounted on the mounting shaft 142. The first end of the first elastic member 170 is connected to the mounting base 110, and the second end is connected to the first end of the rack 151. When the connector and the plug interface 121 are plugged in, the second end of the rack 151 is pushed to compress the first elastic member 170. The rack 151 drives the gear 152 and the mounting shaft 142 to rotate, thereby rotating and moving the baffle 141 away from the position covering the plug interface 121. When the connector and the plug interface 121 are separated, the rack 151 is reset under the elastic force of the first elastic member 170, so that the baffle 141 covers the plug interface 121.
[0049] When the connector is inserted into the insertion interface 121 of the connector body 120, the second end of the rack 151 is pushed, causing the rack 151 to retract into the mounting cavity and compress the first elastic element 170. The retraction of the rack 151 drives the gear 152 to rotate. Since the gear 152 is fixed to the mounting shaft 142, it drives the mounting shaft 142 to rotate synchronously around the inner wall of the mounting cavity. When the mounting shaft 142 rotates, it drives the baffle 141 connected to it to rotate together, moving the baffle 141 from its initial position covering the insertion interface 121. When the connector is separated from the interface 121, the thrust of the connector on the second end of the rack 151 disappears, the compressed first elastic element 170 releases its elastic force, and pushes the rack 151 to reset outward of the housing 130. During the reset process, the rack 151 drives the meshing gear 152 to rotate in the opposite direction. The gear 152 drives the mounting shaft 142 to rotate in the opposite direction synchronously. The mounting shaft 142 then drives the baffle 141 to rotate in the opposite direction until the baffle 141 rotates back to the position that completely covers the interface 121, thus completing the blocking action.
[0050] In this embodiment, a transmission method employing the meshing of rack 151 and gear 152 is adopted. This method offers high transmission precision and efficiency, enabling precise conversion between the linear extension / retraction of rack 151 and the rotational motion of mounting shaft 142. This ensures accurate and controllable rotation angle of baffle 141, preventing issues such as incomplete baffle removal affecting connector insertion or incomplete shielding. Gear 152 is directly mounted on mounting shaft 142, reducing intermediate transmission components, simplifying the transmission structure, lowering the probability of transmission failure, and improving the efficiency of the transmission mechanism 150. The stability and service life of the first elastic element 170 are directly connected between the mounting base 110 and the rack 151. The elastic force is direct and stable, which can ensure that the rack 151 can quickly and smoothly reset after the connector is separated. This will drive the baffle 141 to block the plug interface 121 in time. Combined with the blocking effect of the baffle 141 and the wrapping effect of the mounting cavity of the housing 130, the splashing path of the pressurized coolant inside the liquid cooling system can be blocked from the source, preventing the leaked coolant from splashing onto the core components of the server, and further improving the practicality and reliability of the anti-splash connector 100.
[0051] In the above embodiments, the transmission mechanism 150 may further include a linkage 153. The first end of the linkage 153 is inserted into the mounting cavity, and the second end extends out of the housing 130. The rack 151 is elastically connected to the linkage 153. When the connector is inserted into the insertion interface 121, the second end of the linkage 153 is pushed to drive the gear 152 and the mounting shaft 142 to rotate, thereby rotating and moving the baffle 141 away from the position covering the insertion interface 121. When the connector is inserted into the interface 121, the connector first pushes the second end of the linkage 153 extending out of the housing 130, causing the linkage 153 to move into the mounting cavity. During the movement of the linkage 153, it drives the rack 151, which is elastically connected to it, to move synchronously. When the rack 151 moves, it compresses the first elastic element 170 and drives the gear 152 to rotate through meshing. The gear 152 then drives the mounting shaft 142 and the baffle 141 to rotate together, causing the baffle 141 to rotate away from the position covering the interface 121. When the connector is separated from the interface 121, the push force of the connector on the linkage 153 disappears, and the rack 151 returns to its linear reset under the elastic force of the first elastic element 170. The reset rack 151 drives the gear 152, the mounting shaft 142, and the baffle 141 to rotate in the opposite direction, causing the baffle 141 to cover the interface 121 again.
[0052] By adding a linkage 153 to form a multi-stage transmission engagement, the insertion force of the connector is first applied to the linkage 153 and then transmitted to the rack 151. This effectively buffers the instantaneous impact force during insertion, preventing wear, jamming, or damage to the rack 151 and gear 152 due to excessive direct force, thus improving the durability and operational stability of the transmission mechanism 150. The rack 151 and linkage 153 adopt an elastic connection method, which can compensate for positional deviations and assembly errors during insertion, ensuring that the rack 151 and gear 152 are always stably meshed, guaranteeing the precise and reliable rotation of the baffle 141, and preventing transmission jamming. The baffle 141 is not moved out of place or the shielding is not tight. During the insertion and separation of the connector, the linkage 153, rack 151, gear 152, mounting shaft 142 and baffle 141 are synchronized and linked. The action response is fast and the connection is smooth. When separated, the baffle 141 can quickly reset to shield the insertion interface 121. With the closed space of the mounting cavity of the housing 130, the path of pressurized coolant splashing outward from the insertion interface 121 is effectively blocked, avoiding coolant leakage and splashing that could damage the core components of the server and cause server operation interruption. This significantly improves the anti-splash effect of the connector and the operational safety of the server liquid cooling system.
[0053] In the above embodiments, the transmission mechanism 150 may further include a second elastic element 154 and a first guide post 155. The linkage 153 has a blind hole 1531 and a groove 1532. One side of the rack 151 is connected to the first guide post 155. One end of the second elastic element 154 is sleeved on the first guide post 155, and the other end passes through the blind hole 1531. The second end of the rack 151 is slidably connected to the groove 1532. When the connector is inserted into the interface 121, the connector pushes the second end of the linkage 153 to move it into the mounting cavity. The linkage 153 squeezes the second elastic element 154 through the inner wall of the blind hole 1531. The second elastic element 154 is compressed and the force is transmitted to the rack 151 through the first guide post 155, driving the rack 151 to slide linearly along the groove 1532 of the linkage 153. When the rack 151 slides, it drives the meshing gear 152 to rotate. The mounting shaft 142 and the baffle 141 are rotated, causing the baffle 141 to move away from the position covering the insertion interface 121 to ensure that the connector can be inserted smoothly. When the connector is separated from the insertion interface 121, the thrust on the linkage 153 disappears, and the second elastic element 154 releases its elastic force to push the first guide post 155 and the rack 151 to reset. The rack 151 then drives the gear 152, the mounting shaft 142 and the baffle 141 to rotate in the opposite direction, so that the baffle 141 covers the insertion interface 121 again.
[0054] The first guide post 155 positions and constrains the second elastic element 154, preventing it from tilting, dislodging, or failing during extension and retraction, thus ensuring stable and accurate force transmission. The blind hole 1531 accommodates both the second elastic element 154 and the first guide post 155, providing space for elastic deformation and achieving a compact structure. The sliding engagement of the rack 151 and the groove 1532 constrains the rack 151's movement trajectory, preventing it from shifting and failing to mesh with the gear 152, thus improving transmission smoothness. The second elastic element 154 forms a buffer transition between the linkage 153 and the rack 151, offsetting impacts and assembly gap errors during connector insertion, preventing rigid collisions from causing component wear and damage, and ensuring reliable meshing between the rack 151 and the gear 152. This allows for smooth and sensitive rotation and blocking of the baffle 141, quickly resetting and sealing after separation from the insertion interface 121, further improving the reliability, structural stability, and overall splash protection of the transmission mechanism 150.
[0055] In the above embodiment, a limiting part 1533 may be formed on one side of the linkage 153, and the second end of the housing 130 has a second mounting port that communicates with the mounting cavity. The second end of the linkage 153 is configured to pass through the second mounting port from the first end of the housing 130. Before the connector is inserted into the insertion interface 121, the limiting part 1533 abuts against the inner wall of the mounting cavity under the elastic force of the first elastic member 170 and the second elastic member 154. Before insertion, the first elastic element 170 applies an outward elastic force to the rack 151, and the second elastic element 154 forms an elastic support between the rack 151 and the linkage 153. The dual elastic forces jointly drive the linkage 153 to move outward until the limiting part 1533 abuts against the inner wall of the mounting cavity to achieve positioning, so that the second end of the linkage 153 remains in the preset initial position extending out of the housing 130. At the same time, the baffle 141 stably covers the insertion interface 121 under the transmission action. When the connector is inserted into the insertion interface 121, the connector pushes the extended second end of the linkage 153, so that the linkage 153 overcomes the elastic forces of the first elastic element 170 and the second elastic element 154 and moves into the mounting cavity, and the limiting part 1533... When disengaged from the contact state, the linkage 153 drives the rack 151 to slide along the slide groove 1532 via the second elastic element 154 and the first guide post 155. The rack 151 drives the gear 152 and the mounting shaft 142 to rotate, thereby causing the baffle 141 to rotate away from the insertion interface 121 position, ensuring smooth insertion of the connector. When separated, the connector thrust disappears, and the first elastic element 170 and the second elastic element 154 release their elastic force simultaneously, pushing the rack 151 and the linkage 153 to reset. The limiting part 1533 re-abuts against the inner wall of the mounting cavity for positioning. At the same time, the rack 151 drives the gear 152, the mounting shaft 142 and the baffle 141 to rotate, so that the baffle 141 tightly covers the insertion interface 121 again.
[0056] By engaging with the inner wall of the mounting cavity through the limiting part 1533, the linkage 153, rack 151, and baffle 141 are precisely initially positioned before insertion. This prevents the linkage 153 from extending excessively or shifting its position, ensuring that the baffle 141 stably covers the insertion interface 121 in its initial state. At the same time, it ensures that the extension height of the second end of the linkage 153 is adapted to the insertion path of the connector. The first elastic element 170 and the second elastic element 154 work together to achieve initial limiting and reset drive. The dual elastic force ensures rapid action response and reliable reset. The limiting structure, together with the second mounting port, guides the insertion of the linkage 153, further constraining the movement trajectory of the linkage 153, preventing shaking or jamming, and improving the overall transmission continuity.
[0057] In the above embodiment, the mounting base 110 may have a receiving groove 111 on the side facing the housing 130. A second guide post 112 is provided at the bottom of the receiving groove 111, and the first end of the first elastic member 170 is sleeved on the second guide post 112. It can be understood that the second guide post 112 can accurately position and constrain the first elastic member 170, preventing the first elastic member 170 from tilting, twisting, or dislodging during compression and reset, ensuring that the elastic force of the first elastic member 170 is always transmitted in a straight line, ensuring the accurate movement trajectory of the rack 151, and avoiding the rack 151 and gear 152 meshing failure and transmission jamming due to elastic force deviation; the receiving groove 111 provides sufficient space for the extension and retraction of the first elastic member 170, and at the same time provides a limiting protection for one end of the rack 151, preventing the rack 151 from deviating during movement. This design further enhances the operational stability of the transmission mechanism 150. The first elastic element 170 is stably connected to the mounting base 110 via the second guide post 112. Combined with the constraint of the second elastic element 154 by the first guide post 155, the elastic force transmission of the dual elastic structure is more stable and the reset is more reliable. This ensures that the baffle 141 tightly covers the insertion interface 121 during initial positioning and quickly resets during separation. Simultaneously, the simple structure of the guide post and elastic element facilitates assembly, reducing component assembly errors, decreasing the probability of transmission failures, and improving the overall reliability and service life of the anti-splash connector 100. The receiving groove 111 can accommodate the ends of the rack 151 and the linkage 153, fully utilizing the internal space of the housing 130 and allowing the linkage 153 to be completely retracted into the housing 130.
[0058] In the above embodiments, there may be two connector bodies 120, which are used for the input and output of coolant to the liquid cooling system, respectively. The housing 130 has two first mounting ports 131 corresponding to the positions of the connector bodies 120. When the connector is inserted into the connector body 120, the connection ends of the two connectors extend into the mounting cavity through the corresponding two first mounting ports 131 on the housing 130, realizing the synchronous connection of the coolant input and output circuits. When the connector is separated from the connector body 120, the two linkages 153 are synchronously reset under the combined elastic force of the first elastic member 170 and the second elastic member 154. The dual-connector body 120 corresponds to the coolant input and output circuits respectively, which can meet the complete path requirements of the server liquid cooling system for heat dissipation circulation and achieve integrated anti-splash protection for the coolant inlet and outlet pipes. The housing 130 is provided with two first mounting ports 131, which not only ensures that the two plug-in paths are independent and do not interfere with each other, but also confines the two plug-in ports 121 within the mounting cavity, achieving unified isolation of leakage and splashing from the input and output interfaces. The two interfaces share the same set of transmission and shielding logic, with a compact structure and high linkage consistency, which can ensure that the input and output connectors open and close synchronously, avoiding the risk of splashing caused by leakage in a single circuit. In the separated state, the two baffles 141 simultaneously close the corresponding plug-in ports 121, forming a double-sealed protection with the mounting cavity of the housing 130. Regardless of whether the coolant input interface or the output interface leaks due to internal pressure, it can effectively block the coolant from splashing outward, comprehensively protecting the core components of the server, preventing hardware damage and operation interruption caused by liquid cooling leakage, and improving the compatibility of the connector with the complete liquid cooling circulation system and the overall protection reliability.
[0059] In the above embodiments, a pipe connector 160 may also be included. The mounting base 110 has a first interface and a second interface that are connected to each other on opposite sides. The first end of the pipe connector 160 is connected to the first interface, and the second end is used to connect to the liquid cooling system. The first end of the connector body 120 is connected to the second interface. It is understood that the coolant flows into the mounting base 110 through the pipe connector 160, enters the connector body 120 through the connecting channel between the first and second interfaces, and then circulates the coolant input and output through the insertion interface 121 of the connector body 120 and the external connector. The pipe connector 160 and the connector body 120 are stably connected through the interconnected first and second interfaces on the mounting base 110, forming a sealed and unobstructed coolant flow channel, ensuring reliable connection of the input and output circuits of the liquid cooling system, and avoiding additional leakage points at the interface connection. The pipe connector 160 is directly connected to the liquid cooling system, making the integration and installation of the entire splash-proof connector 100 with the server liquid cooling system more convenient, and the structural layout is compact and reasonable. The mounting base 110, as an intermediate transition component, provides a stable installation foundation for the connector body 120 and provides installation support for the first elastic element 170 and the second guide post 112, improving the overall structural strength and assembly accuracy. In addition, through the design of the first and second interfaces on both sides of the mounting base 110, the connector body 120 and the pipe connector 160 can be assembled from both sides of the mounting base 110 respectively, realizing bidirectional split installation, simplifying the assembly process, reducing assembly difficulty, and improving production and maintenance efficiency.
[0060] The above embodiments may further include a leakage detection element, which can be disposed in the mounting cavity to detect whether there is a coolant leak. By placing the leakage detection element in the mounting cavity, real-time monitoring and accurate identification of coolant leaks can be achieved, enabling rapid detection of abnormalities in the early stages of a leak and preventing the leak from continuing to expand and causing a large amount of coolant splashing. Combined with the shielding structure of the baffle 141 and the enclosure structure of the housing 130, timely measures such as shutdown maintenance can be taken after a leak is detected, further reducing the risk of coolant splashing damaging the core components of the server. The mounting cavity provides a stable installation space for the leakage detection element and can also collect a small amount of leaked coolant, facilitating stable identification by the detection element, improving detection accuracy, and further enhancing the operational safety and reliability of the server liquid cooling system. Specifically, the leakage detection element can be a liquid sensor probe, a leakage detection line, or other detection components.
[0061] Furthermore, this application embodiment also provides a server, including the splash-proof connector 100 of the above embodiments. The connector end of the coolant supply system can extend from the first mounting port 131 of the housing 130 into the mounting cavity and be inserted into the insertion interface 121 of the connector body 120. The housing of the connector synchronously pushes the second end of the transmission mechanism 150 to retract into the mounting cavity, causing the shielding component 140 to move away from the position covering the insertion interface 121. When the connector is separated from the insertion interface 121, the transmission mechanism 150 resets to the outside of the housing 130 under the elastic force of the first elastic member 170. Since the connector 121 is always located within the mounting cavity of the housing 130, and the shielding component 140 can quickly shield the connector 121 when the connector is separated, even if there is pressure inside the liquid cooling system causing coolant to leak from the connector 121, the leaked coolant will be confined within the mounting cavity of the housing 130. At the same time, the shielding component 140 directly blocks the connector 121, cutting off the path of coolant splashing outward from the source of leakage, preventing coolant from splashing onto the core components inside the server, and improving the server's protection and reliability.
