Description

Technical Field

[0001] The present invention relates to the technical field of electrical components, and particularly to a connector and a network device. Background Art

[0002] Network devices and components are physical entities connected to a network. Basic network devices include: computers (whether personal computers or servers), hubs, switches, bridges, routers, gateways, network interface cards (NICs), wireless access points (WAPs), printers and modems, fiber optic transceivers, optical cables, etc. Among them, the server is the center of the network and the core of informatization, with characteristics such as high performance, high reliability, high availability, strong I / O throughput capacity, large storage capacity, strong networking and network management capabilities. According to the chassis architecture of the server, it can be divided into desktop servers, rack-mounted servers, cabinet servers, and blade servers.

[0003] In the case of rack-mounted servers, multiple layers of servo computer systems are configured to flow on the server rack. The cooling problem of each servo computer system has always been one of the most concerned issues. In the prior art, in order to improve the heat dissipation efficiency, the air-cooling method is replaced by the water-cooling method. The water-cooling requires providing a liquid flow loop. During the use of each servo computer system, one or more servo computer systems need to be frequently taken out and put into the rack. In this way, it is necessary to continuously connect and separate each servo computer system from the liquid loop, which may easily lead to liquid leakage. Therefore, the prior art has also given improvement solutions:

[0004] For example, in the Chinese invention patent with the application number CN201910553120.7, the publication (announcement) number CN111328237B, and the name "Connector Assembly and Server Rack", based on the setting of the flexible part, after the first connector and the second connector are coupled to each other, the flexible part of the connector assembly can maintain flexion when needed. The connector assembly allows the sliding part or any component to quickly connect and separate from the liquid cooling manifold system without liquid coolant leakage.

[0005] However, the applicant found in the actual operation process that there are at least the following drawbacks in the prior art and the above-mentioned patent:

[0006] Since the liquid inlet pipe and the outlet pipe of the servo computer system need to be connected to two liquid manifolds in a one-to-one correspondence to form a closed liquid circuit, and the connection method is through the connection of pipe bodies, the liquid always fills the inlet pipe, the outlet pipe of the servo computer system and the pipe bodies located on the two liquid manifolds connected thereto (hereinafter collectively referred to as "connection pipes"). When a certain servo computer system is removed from the rack, after the inlet pipe and the outlet pipe of the servo computer system are separated from the corresponding connection pipes, since the inlet pipe, the outlet pipe and the two connection pipes are all filled with liquid, the liquid will flow out of the inlet pipe, the outlet pipe and the two connection pipes of the servo computer system after separation and drip onto the lower servo computer system. If it drips on its shell, it needs to be wiped, which increases the workload of the operator. If it happens to drip on the circuit, it is also likely to cause a short circuit of the circuit, resulting in unnecessary trouble. Therefore, how to prevent the liquid from flowing out and dripping onto the lower servo computer system when the servo computer system is removed is a technical problem to be solved urgently. Summary of the Invention

[0007] The purpose of the present invention is to provide a connector and a network device to solve the above deficiencies in the prior art.

[0008] To achieve the above purpose, the present invention provides the following technical solutions: A connector includes two connection pipes that are connected to the inlet and outlet of the servo computer system in a one-to-one correspondence, and two connection components that are hermetically and slidably inserted into the two connection pipes in a one-to-one correspondence. The connection component includes a fixed adapter block. A liquid flow channel and a jack are formed in the adapter block and are connected to each other. The connection pipe is inserted into the jack and is connected to the liquid flow channel through an opening. An activity pipe that is in contact with and coaxial with the connection pipe is elastically and hermetically slidably inserted into the jack. A sealing cavity is formed in the jack on the side of the activity pipe away from the connection pipe;

[0009] A central core column fixedly connected to the adapter block is hermetically and slidably inserted into the activity pipe. One end of the central core column close to the connection pipe is connected to a suction ball through a straw, and the suction ball is located in the inner cavity of the connection pipe;

[0010] A suction port that abuts against the bottom of the inner cavity of the connection pipe is formed in the suction ball. A drainage channel is formed in the central core column. The suction port is connected to the sealing cavity through the inner cavity of the straw and the drainage channel in sequence;

[0011] During the process of pulling the connection pipe outwards to separate it from the corresponding connection component, the activity pipe is driven to elastically slide towards the connection pipe. The sliding of the activity pipe seals the opening on one side and generates negative pressure in the sealing cavity on the other side, so that the liquid in the connection pipe is sucked into the sealing cavity by the suction port and stored.

[0012] In the above-mentioned connector, the bottom of the inner cavity of the connecting tube is inclined downward toward the direction of the movable tube so that part of the liquid in its inner cavity passes over the suction ball and flows into the movable tube during the movement of the connecting tube. When the connecting tube is separated from the connecting assembly, the suction ball abuts against the port of the movable tube to block the port of the movable tube.

[0013] In the above connector, the straw is elastic.

[0014] The above-mentioned connector also includes two locking members fixedly connected to the two adapter blocks in a one-to-one correspondence. The servo computer system includes a locking plate fixedly connected thereto. The locking plate is provided with two locking holes that match the two locking members in a one-to-one correspondence. When the connecting tube is inserted into a specific position in the socket, the locking member locks the locking plate so that the connecting tube is locked in the connecting assembly.

[0015] The above-mentioned connector, the locking piece includes a fixing rod fixedly plugged with the adapter block, and the fixing rod is elastically rotatably provided with two symmetrically arranged rotating rods, and one end of the fixing rod away from the adapter block is fixedly installed with an abutment plate that abuts and cooperates with the two rotating rods. In the initial state, the two rotating rods abut against the abutment plate, and during the process of inserting the connecting tube into the sealing cavity, the inner wall of the locking hole and the outer side surfaces of the two rotating rods slide and squeeze to push the two rotating rods to rotate toward the fixing rod, and when the locking hole passes over the two rotating rods, the two rotating rods elastically rotate and reset and abut against the abutment plate so that the locking plate is locked between the rotating rod and the adapter block, at this time, the opening is connected to the liquid flow channel.

[0016] In the above-mentioned connector, a vent hole connected to the liquid flow channel is provided in the fixed rod, and a sealing fixed sleeve at the port of the vent hole is provided with an air bag located in the liquid flow channel. An inflatable member is connected between any of the rotating rods and the fixed rod, and during the process of the two rotating rods rotating toward one side of the fixed rod, the inflatable member drives the gas into the air bag to expand the air bag and block the liquid flow channel, so that when the connecting tube is pulled out from the socket and the opening and the liquid flow channel are offset, no liquid will continue to pass through the liquid flow channel into the inner cavity of the connecting tube.

[0017] The above-mentioned connector, the inflatable part includes a cylinder body fixedly connected to the fixed rod and communicated with the vent, a piston rod is sealed and slidably inserted in the cylinder body, a spherical top rod is fixedly installed on the top of the piston rod, the spherical top rod includes a ball head and a rod body, the ball head of the spherical top rod is slidably engaged in a slide groove provided on the rotating rod, and when the rotating rod rotates toward the fixed rod, the piston rod is pressed down by the spherical top rod to slide toward the inside of the upper cylinder so that the gas enters the airbag through the vent.

[0018] The above-mentioned connector, the cylinder body includes an upper cylinder body and a lower cylinder body which are coaxially connected and fixedly connected to the fixed rod. The upper cylinder body is located above the fixed rod, and the lower cylinder body is located below the fixed rod. The lower cylinder body is communicated with the ventilation hole through a branch pipe.

[0019] The above-mentioned connector, two baffles are fixedly installed on the rotating rod and are arranged oppositely and abut against the spherical head of the spherical ejector rod. The two baffles block part of the sliding groove so that the spherical head of the spherical ejector rod is slidably clamped in the sliding groove.

[0020] A network device, including the above-mentioned connector, further includes a frame. A plurality of groups of support plates arranged oppositely up and down are fixedly installed on the inner wall of the frame. Each group of support plates is used to support a servo computer system. When the bottom of the servo computer system fits against the top of the support plate, the connecting pipe and the corresponding sealing cavity are coaxial.

[0021] Beneficial effects:

[0022] 1. In the above technical solution, for the connector and the network device provided by the present invention, through the design of the connection component, by using the elastic sliding of the movable pipe and the sealed sliding insertion between the central core column and the movable pipe, when the connecting pipe is separated from the connection component, the movable pipe can be elastically slid. The sliding of the movable pipe not only blocks the opening to prevent the liquid from flowing out of the connection component, but also drives a negative pressure to be generated in the sealing cavity so that the liquid in the connecting pipe is sucked into the sealing cavity by the suction port and stored. Thus, the amount of liquid in the connecting pipe is greatly reduced, so that after the connecting pipe is separated from the connection component, the liquid in the inner cavity of the connecting pipe is not likely to flow out and drip on the lower-layer servo computer system. At the same time, part of the liquid in the connection component is blocked in the liquid flow channel by the movable pipe, part is stored in the sealing cavity, the drainage channel and the inner cavity of the straw. Therefore, the liquid is not likely to flow out of the connection component and drip on the lower-layer servo computer system. It can be seen that during the sliding process, the movable pipe can not only block the connection component, but also make the liquid not likely to flow out and drip on the lower-layer servo computer system after the connecting pipe is separated from the connection component, which can effectively solve the deficiencies in the prior art;

[0023] 2. In the present invention, through the further improvement of the structure of the connecting pipe and the ingenious cooperation between the suction ball and the movable pipe, when the connecting pipe is removed, the liquid in its inner cavity can not only be further reduced by flowing into the movable pipe, but also when the further reduced liquid in the connecting pipe flows into the inner cavity of the movable pipe, it can be blocked by the suction ball and cannot flow out and drip. In this way, the technical problem of liquid flowing out and dripping at the connection when the servo computer system is disassembled can be better solved. Moreover, the presence of the suction ball not only enables the suction ball to suck the liquid in the inner cavity of the connecting pipe, but also plays a role in blocking the port of the movable pipe, so that the liquid in the movable pipe cannot flow out and drip, producing an unexpected technical effect;

[0024] 3. In the present invention, when the locking plate is released from the limit by rotating two rotating rods, the rotating rods can also drive the inflating member to inflate the airbag, so that the airbag blocks the liquid flow path, thereby ensuring that the liquid will not flow into the inner cavity of the connecting pipe during the process of staggering the opening and the liquid flow path. This is more conducive to the discharge of the liquid in the inner cavity of the connecting pipe before the connecting pipe is completely removed from the jack. It can be seen that while the rotating rods release the limit on the locking plate, they also achieve an unexpected technical effect. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0041] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] First embodiment:

[0043] As Figure 1-13 shown, a connector provided by an embodiment of the present invention includes two connecting pipes 402 corresponding to and communicating with the inlet 4012 and the outlet 4013 of the servo computer system 4 one by one, and two connecting components corresponding to and hermetically and slidably inserted into the two connecting pipes 402. The connecting components include fixedly arranged adapter blocks 5. A liquid flow channel 501 and a jack communicating with each other are formed in the adapter block 5. The connecting pipe 402 is inserted into the jack and communicated with the liquid flow channel 501 through the opening 4021. An activity pipe 23 that abuts against and is coaxial with the connecting pipe 402 is elastically and hermetically slidably inserted into the jack. A sealing cavity 502 is formed in the jack on the side of the activity pipe 23 away from the connecting pipe 402;

[0044] A central core column 22 fixedly connected to the adapter block 5 is hermetically and slidably inserted into the movable tube 23. One end of the central core column 22 close to the connecting tube 402 is connected to a suction ball 20 through a straw 21, and the suction ball 20 is located in the inner cavity of the connecting tube 402;

[0045] A suction port 2001 that abuts against the bottom of the inner cavity of the connecting tube 402 is formed in the suction ball 20. A drainage channel 2201 is formed in the central core column 22. The suction port 2001 is communicated with the sealing cavity 502 in sequence through the inner cavity of the straw 21 and the drainage channel 2201;

[0046] During the process of pulling the connecting tube 402 outwards to separate it from the corresponding connecting component, the movable tube 23 is elastically slid towards the connecting tube 402. The sliding of the movable tube 23 seals the opening 4021 on one side and drives a negative pressure to be generated in the sealing cavity 502 on the other side so that the liquid in the connecting tube 402 is sucked into the sealing cavity 502 by the suction port 2001 for storage.

[0047] The connector provided in this embodiment is used to hermetically connect a servo computer system or various devices used to replace the servo computer system with a liquid path in a rack to form a complete liquid loop. The words related to directions and positions in the present invention are relative to the attached drawings. Specifically, the servo computer system 4 includes a locking plate 401 fixedly connected thereto. An inlet 4012 and an outlet 4013 on the servo computer system 4 are opened on the locking plate 401. Two inner channels 4014 corresponding to the inlet 4012 and the outlet 4013 one by one are further opened in the locking plate 401. The two inner channels 4014 are in one-to-one correspondence and communication with the two ports of the liquid channel inside the servo computer system 4. Cold liquid flows into the servo computer system 4 from the inlet 4012 of the servo computer system 4 to absorb heat and form hot liquid, and the hot liquid then flows out from the outlet 4013 of the servo computer system 4. Two connecting pipes 402 are fixedly installed on the locking plate 401. The two connecting pipes 402 are in one-to-one correspondence and communication with the inlet 4012 and the outlet 4013. The two connecting pipes 402 are inserted into the adapter blocks 5 in the two connecting components one by one. The present invention further includes a first liquid manifold 2 and a second liquid manifold 3 arranged oppositely. One of the connecting components is fixedly installed on the first liquid manifold 2, and the other connecting component is fixedly installed on the second liquid manifold 3. The first liquid manifold 2 is connected to a liquid supply mechanism that provides liquid (not shown in the figure), and the first liquid manifold 2 is communicated with the adapter block 5 in one of the connecting components through a communication pipe 19. Cold liquid flows from the first liquid manifold 2 through the communication pipe 19 into the adapter block 5, then flows through the adapter block 5 into the corresponding connecting pipe 402, and then flows through the inlet 4012 and the inner channel 4014 into the liquid channel inside the servo computer system 4 to cool the servo computer system 4; the second liquid manifold 3 is communicated with the adapter block 5 in the other connecting component through another communication pipe 19. After the cold liquid that has cooled the servo computer system 4 becomes hot liquid, the hot liquid flows through the other inner channel 4014 and the outlet 4013 into the other connecting pipe 402, then flows into the other adapter block 5, and then flows through another communication pipe 19 into the second liquid manifold 3 and is discharged, thus forming a cycle. There are multiple servo computer systems 4 in the present invention. The multiple servo computer systems 4 are arranged vertically. Each servo computer system 4 is configured with two connecting components. The cold liquid flowing out from the first liquid manifold 2 will be supplied to multiple servo computer systems 4 for use at the same time. The liquid flow channel 501 opened in the adapter block 5 is communicated with the communication pipe 19. The jacks opened in the adapter block 5 are used for the connecting pipe 402 to be hermetically and slidably inserted. The two connecting pipes 402 on the servo computer system 4 are hermetically and slidably inserted into the jacks in the two adapter blocks 5 one by one. An opening 4021 is opened on the connecting pipe 402. The opening 4021 is communicated with the inner cavity of the connecting pipe 402. When the installation of the servo computer system 4 is completed, the opening 4021 is communicated with the liquid flow channel 501, so that the liquid flow channel 501 is communicated with the inner cavity of the connecting pipe 402.An active tube 23 that is in contact with and coaxial with the connecting tube 402 is elastically and sealingly inserted into the socket. Based on the existence of the active tube 23, the socket is divided into two parts, one part is located on the side of the active tube 23 close to the connecting tube 402, and the other part is located on the side of the active tube 23 away from the connecting tube 402. The socket located on the side of the active tube 23 away from the connecting tube 402 is a sealed cavity 502. Since the active tube 23 is elastically slidably arranged, the volume of the sealed cavity 502 changes when the active tube 23 slides.

[0048] A central column 22 fixedly connected to the adapter block 5 is sealed and slidably inserted in the movable tube 23, and one end of the central column 22 close to the connecting tube 402 is connected to a suction ball 20 through a suction tube 21, and the suction ball 20 is located in the inner cavity of the connecting tube 402; a suction port 2001 abutting against the bottom of the inner cavity of the connecting tube 402 is provided in the suction ball 20, a drainage channel 2201 is provided in the central column 22, and the suction port 2001 is connected to the sealed cavity 502 through the inner cavity of the suction tube 21 and the drainage channel 2201 in sequence.

[0049] Based on the design of the above structure, its working principle is as follows: before the connecting tube 402 is separated from the connecting component, the liquid will always exist in the inner cavity of the connecting tube 402. When the servo computer system 4 needs to be disassembled and removed, the servo computer system 4 is pulled outward by external force, so that the servo computer system 4 drives the two connecting tubes 402 to move synchronously to the outside of the corresponding sockets. At this time, the connecting tube 402 is gradually separated from the corresponding connecting component. In the process of the connecting tube 402 moving to the outside of the corresponding socket, based on the elastic sliding of the movable tube 23, the end of the movable tube 23 is always in contact with the end of the connecting tube 402 during the movement of the connecting tube 402, and then the movable tube 23 continuously slides elastically toward the connecting tube 402 during the movement of the connecting tube 402. When the opening 4021 is staggered with the liquid flow channel 501, the movable tube 2 The liquid flow channel 501 is blocked. At the same time, based on the sealed sliding plug-in connection between the central core column 22 and the movable tube 23, a negative pressure is generated in the sealed cavity 502 during the sliding process of the movable tube 23 toward the connecting tube 402. Under the action of the negative pressure, the liquid in the connecting tube 402 is sucked by the suction port 2001, and sequentially passes through the inner cavity of the suction tube 21 and the drainage channel 2201 to enter the sealed cavity 502 for storage, so that after the connecting tube 402 is separated from the connecting component, the liquid in the inner cavity of the connecting tube 402 is not easy to flow out and drip onto the servo computer system 4 at the lower layer. At the same time, part of the liquid in the connecting component is blocked in the liquid flow channel 501 by the movable tube 23, and part of the liquid is stored in the sealed cavity 502, the drainage channel 2201 and the inner cavity of the suction tube 21, so that it is not easy to flow out from the connecting component and drip onto the servo computer system 4 at the lower layer.

[0050] It can be seen that through the design of the connection component, the present invention makes use of the elastic sliding of the movable tube 23 and the sealed sliding insertion between the core column 22 and the movable tube 23, so that during the process of separating the connecting tube 402 from the connection component, the movable tube 23 can be elastically slid. The sliding of the movable tube 23 blocks the opening 4021 on one hand to prevent the liquid from flowing out of the connection component, and on the other hand, drives the generation of negative pressure in the sealing cavity 502 so that the liquid in the connecting tube 402 is sucked into the sealing cavity 502 by the suction port 2001 and stored, thereby greatly reducing the amount of liquid in the connecting tube 402. After the connecting tube 402 is separated from the connection component, the liquid in the inner cavity of the connecting tube 402 is not likely to flow out and drip onto the lower servo computer system 4. At the same time, part of the liquid in the connection component is blocked in the liquid flow channel 501 by the movable tube 23, part is stored in the sealing cavity 502, the drainage channel 2201 and the inner cavity of the straw 21, so that the liquid is not likely to flow out of the connection component and drip onto the lower servo computer system 4. Therefore, at least two different technical effects are generated during the sliding process of the movable tube 23, and the deficiencies in the prior art can be effectively solved.

[0051] Further, the bottom of the inner cavity of the connecting tube 402 slopes downward toward the movable tube 23 so that during the movement of the connecting tube 402, part of the liquid in its inner cavity crosses the suction ball 20 and flows into the movable tube 23. When the connecting tube 402 is separated from the connection component, the suction ball 20 fits and abuts against the port of the movable tube 23 to block the port of the movable tube 23. Specifically, since it is difficult to completely suck the liquid in the inner cavity of the connecting tube 402 when the suction port 2001 sucks the liquid, in the present invention, the bottom height of the port where the inner cavity of the connecting tube 402 abuts against the inner cavity of the movable tube 23 is the same, and based on the fact that the bottom of the inner cavity of the connecting tube 402 slopes downward toward the movable tube 23, the liquid in the connecting tube 402 can also flow along the bottom of its inner cavity into the inner cavity of the movable tube 23 during the process of being sucked by the suction port 2001. Furthermore, the liquid in the inner cavity of the connecting tube 402 is further reduced so that it is difficult for the liquid in its inner cavity to flow out and drip when the connecting tube 402 is separated from the connection component. At the same time, since the suction ball 20 blocks the port of the movable tube 23 when the connecting tube 402 is separated from the connection component, the liquid entering the inner cavity of the movable tube 23 cannot flow out, so that the liquid in the connection component is also difficult to flow out and drip.

[0052] It can be seen that in the present invention, through the further improvement of the structure of the connecting pipe 402 and the ingenious cooperation between the suction ball 20 and the movable pipe 23, when the connecting pipe 402 is removed, not only can the liquid in its inner cavity be further reduced by flowing into the movable pipe 23, but also the further reduced liquid in the connecting pipe 402 flowing into the inner cavity of the movable pipe 23 can be blocked by the suction ball 20 and cannot flow out and drip. In this way, the technical problem of liquid flowing out and dripping at the connection when the servo computer system 4 is disassembled can be better solved. Moreover, the presence of the suction ball 20 enables the suction ball 20 not only to suck the liquid in the inner cavity of the connecting pipe 402, but also to block the port of the movable pipe 23, so that the liquid located in the movable pipe 23 cannot flow out and drip either, producing an unexpected technical effect.

[0053] Among them, the suction pipe 21 has elasticity and can elastically deform in the radial reverse direction, so that the suction port 2001 can always abut against the bottom of the inner cavity of the connecting pipe 402 during the movement of the connecting pipe 402, and it is also beneficial for the suction ball 20 to better enter the connecting pipe 402 when the connecting pipe 402 is inserted into the jack in the adapter block 5.

[0054] In this embodiment, the connector further includes two locking members 6 fixedly connected to the two adapter blocks 5 in one-to-one correspondence. The servo computer system 4 includes a locking plate 401 fixedly connected thereto. Two locking holes 4011 are provided on the locking plate 401 and are in one-to-one correspondence and cooperation with the two locking members 6. When the connecting pipe 402 is inserted into a specific position in the jack, the locking member 6 locks the locking plate 401 so that the connecting pipe 402 is locked in the connecting component. Specifically, a compression spring 24 is installed between the inner wall of the movable pipe 23 and the sealing cavity 502. The compression spring 24 is always in a compressed state. Based on the compression elastic force of the compression spring 24, the elastic sliding of the movable pipe 23 is realized. When the connecting pipe 402 is inserted into the corresponding jack, the movable pipe 23 is pushed to slide towards the sealing cavity 502, causing the compression spring 24 to be continuously compressed. Under the action of the elastic force of the compression spring 24, the connecting pipe 402 is subjected to a force away from the sealing cavity 502, and thus the connecting pipe 402 is easily separated from the connecting component. Therefore, in the present invention, by adding the setting of the locking member 6, after the connecting pipe 402 is inserted into a specific position in the jack, the locking member 6 can lock the locking plate 401. Since both the locking plate 401 and the connecting pipe 402 are fixedly connected to the servo computer system 4, after the locking plate 401 is locked, the connecting pipe 402 is also locked, so that the connecting pipe 402 will not slide out when located in the jack.

[0055] Among them, the locking member 6 includes a fixing rod 9 fixedly inserted into the adapter block 5. Two rotating rods 7 arranged symmetrically are elastically rotatably arranged on the fixing rod 9. An abutting plate 12 that abuts and cooperates with the two rotating rods 7 is fixedly installed at one end of the fixing rod 9 away from the adapter block 5. In the initial state, the two rotating rods 7 abut against the abutting plate 12 so that the abutting plate 12 limits the two rotating rods 7. During the process of inserting the connecting pipe 402 into the sealing cavity 502, the inner wall of the locking hole 4011 slides and presses against the outer sides of the two rotating rods 7 to push the two rotating rods 7 to rotate towards the fixing rod 9. When the locking hole 4011 passes over the two rotating rods 7, the two rotating rods 7 elastically rotate and reset and abut against the abutting plate 12 so that the locking plate 401 is locked between the rotating rod 7 and the adapter block 5. At this time, the opening 4021 communicates with the liquid flow channel 501. Specifically, a return spring 10 is fixedly connected between each of the two rotating rods 7 and the fixing rod 9. The rotating connection between the rotating rod 7 and the fixing rod 9 is realized based on the compression elastic force of the return spring 10. Of course, the return spring 10 can also be replaced by a torsion spring, which will not be elaborated here. A pair of support pieces 11 are fixedly installed at the end of the fixing rod 9. A rotating shaft 8 inserted into the two rotating rods 7 one by one is rotatably arranged on the support pieces 11. One end of the rotating rod 7 is rotatably connected to the fixing rod 9 through the rotating shaft 8, and the other end is used to abut against the side surface of the locking plate 401 to limit the locking plate 401.

[0056] Furthermore, a vent hole 901 connected to the liquid flow channel 501 is provided in the fixed rod 9, and a sealing fixed sleeve of the port of the vent hole 901 is provided with an air bag 18 located in the liquid flow channel 501. An inflatable member is connected between any rotating rod 7 and the fixed rod 9. During the rotation of the two rotating rods 7 toward one side of the fixed rod 9, the inflatable member is driven to pass gas into the air bag 18 to expand the air bag 18 and block the liquid flow channel 501, so that when the connecting tube 402 is pulled out from the insertion hole, when the opening 4021 and the liquid flow channel 501 are offset, no liquid will continue to pass through the liquid flow channel 501 and enter the inner cavity of the connecting tube 402. Specifically, since there is a stage in which the opening 4021 and the liquid flow channel 501 are connected during the process of the connecting tube 402 being removed from the insertion hole, since the liquid flow channel 501 will not be blocked during this stage, the liquid can continuously enter the inner cavity of the connecting tube 402, which is not conducive to the discharge of the liquid in the inner cavity of the connecting tube 402 before the connecting tube 402 is completely removed from the insertion hole. In the present embodiment, when the servo computer system 4 needs to be removed, the two rotating rods 7 need to be rotated toward the fixed rod 9 first so that the ends of the two rotating rods 7 can be inserted into the locking hole 4011, so that the locking plate 401 can be released from the limit. When the two rotating rods 7 are rotated toward the fixed rod 9, on the basis of releasing the locking plate 401, the airbag 18 can be inflated and expanded through the inflatable member. When the airbag 18 expands, its outer side surface squeezes the inner wall of the liquid flow channel 501 to block the liquid flow channel 501. After the liquid flow channel 501 is blocked, the liquid cannot flow into the connecting tube 402. At this time, when the connecting tube 402 is moved, the liquid will not flow into the inner cavity of the connecting tube 402 during the process of the opening 4021 and the liquid flow channel 501 being offset. This is more conducive to the discharge of the liquid in the inner cavity of the connecting tube 402 before the connecting tube 402 is completely removed from the socket, which can effectively solve the above-mentioned technical problems.

[0057] It can be seen that in the present invention, when the two rotating rods 7 are rotated to release the limit on the locking plate 401, the rotating rotating rods 7 can also drive the inflatable part to inflate the airbag 18, so that the airbag 18 blocks the liquid flow channel 501, thereby achieving that in the process of the opening 4021 and the liquid flow channel 501 being offset, the liquid will not flow into the inner cavity of the connecting tube 402, which is more conducive to the discharge of the liquid in the inner cavity of the connecting tube 402 before it is completely removed from the socket. It can be seen that the rotating rod 7 not only releases the limit on the locking plate 401, but also has an unexpected technical effect.

[0058] In this embodiment, the inflatable part includes a cylinder body fixedly connected to the fixed rod 9 and connected to the vent hole 901, and a piston rod 14 is sealed and slidably inserted in the cylinder body. A spherical top rod 15 is fixedly installed on the top of the piston rod 14. The spherical top rod 15 includes a ball head and a rod body. The ball head of the spherical top rod 15 is slidably engaged in a slide groove 701 opened on the rotating rod 7. When the rotating rod 7 rotates toward the fixed rod 9, the piston rod 14 is pressed down by the spherical top rod 15 to slide toward the inside of the upper cylinder 13 so that the gas passes through the vent hole 901 and enters the airbag 18.

[0059] Among them, the cylinder block includes an upper cylinder body 13 and a lower cylinder body 16 that are coaxially connected and fixedly connected to the fixed rod 9. The upper cylinder body 13 is located above the fixed rod 9, and the lower cylinder body 16 is located below the fixed rod 9. The inner cavity diameters of the upper cylinder body 13 and the lower cylinder body 16 are the same. The lower cylinder body 16 is connected to the vent hole 901 through a branch pipe 17.

[0060] Two baffles 702 are fixedly installed on the rotating rod 7 and are arranged oppositely and abut against the spherical head of the spherical ejector rod 15. The two baffles 702 block part of the chute 701 so that the spherical head of the spherical ejector rod 15 is slidably clamped in the chute 701.

[0061] Second Embodiment:

[0062] As Figure 1-13 shown, a network device provided by an embodiment of the present invention includes the above-mentioned connector, and further includes a frame 1. A plurality of groups of support plates 25 arranged oppositely up and down are fixedly installed on the inner wall of the frame 1. Each group of support plates 25 is used to support a servo computer system 4. When the bottom of the servo computer system 4 is attached to the top of the support plate 25, the connecting pipe 402 and the corresponding sealing cavity 502 are coaxial. The frame 1 is used to accommodate the servo computer system 4, the support plate 25 is used to support the servo computer system 4, and the number of servo computer systems 4 is multiple and arranged up and down. When the servo computer system 4 needs to be installed on the frame 1, the bottom of the servo computer system 4 is attached to and abuts against the top of the support plate 25, and then the servo computer system 4 is directly pushed inwardly into the frame 1 so that the two connecting pipes 402 on the servo computer system 4 are inserted into the corresponding sealing cavities 502.

[0063] Among them, a first liquid manifold 2 and a second liquid manifold 3 are fixedly installed on the frame 1 and are arranged oppositely. The first liquid manifold 2 and the second liquid manifold 3 are used to provide channels for the liquid. During operation, the first liquid manifold 2 is connected to a liquid supply mechanism that provides liquid (not shown in the figure), and the first liquid manifold 2 is connected to the adapter block 5 in one of the connection components through a connecting pipe 19. The cold liquid flows from the first liquid manifold 2 through the connecting pipe 19 into the adapter block 5, then flows through the adapter block 5 into the corresponding connecting pipe 402, and then passes through the inlet 4012 and the inner channel 4014 into the liquid channel in the servo computer system 4 to cool the servo computer system 4; the second liquid manifold 3 is connected to the adapter block 5 in another connection component through another connecting pipe 19. After the cold liquid that has cooled the servo computer system 4 becomes hot liquid, the hot liquid flows through another inner channel 4014 and the outlet 4013 into another connecting pipe 402, then flows into another adapter block 5, and then flows through another connecting pipe 19 into the second liquid manifold 3 and is discharged.

Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.
