Description

Technical Field

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

[0002] Network devices and components are physical entities connected to the network. Basic network devices include: computers (whether they are 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 hub of the network and the core of informatization. It has the characteristics of high performance, high reliability, high availability, strong I / O throughput, large storage capacity, strong networking and network management capabilities, etc. It can be divided into desktop servers, rack servers, cabinet servers, and blade servers according to the chassis architecture of the server.

[0003] For rack-mounted servers, multiple layers of servo computer systems are configured on the server racks. The cooling problem of each servo computer system has always been one of the most concerned issues. In the prior art, water cooling is used instead of air cooling to improve the heat dissipation efficiency. Water cooling requires a liquid flow circuit. During use, each servo computer system needs to frequently take one or more servo computer systems out and put them into the rack. In this way, each servo computer system needs to be constantly connected and separated from the liquid circuit, which may easily lead to liquid leakage. For this reason, the prior art also provides an improvement plan: For example, the Chinese invention patent with application number CN201910553120.7, publication (announcement) number CN111328237B, and name “Connector assembly and server rack” is 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 flexibility when needed. The connector assembly allows the sliding part or any component to be quickly connected and separated from the liquid cooling manifold system without leakage of the liquid coolant.

[0004] However, the applicant has found in the actual operation process that the prior art and the above patents have at least the following disadvantages: Since the liquid inlet pipe and outlet pipe of the servo computer system need to be connected to the two liquid manifolds one by one to form a closed liquid circuit, and the connection method is through the connection between the pipe bodies, the liquid always fills the inlet pipe, outlet pipe and the pipe bodies connected to it and located on the two liquid manifolds (hereinafter collectively referred to as "connecting pipes") of the servo computer system. When a servo computer system is removed from the rack, the inlet pipe and outlet pipe of the servo computer system are separated from the corresponding connecting pipes. Since the inlet pipe, outlet pipe and two connecting pipes are full of liquid, the liquid will flow out of the inlet pipe, outlet pipe and two connecting pipes of the servo computer system and drip onto the servo computer system on the lower layer after separation. If it drips on its outer shell, it needs to be wiped, which increases the workload of the operator. If it happens to drip on the line, it will easily cause a short circuit of the line, thereby causing unnecessary trouble. Therefore, how to prevent the liquid from flowing out and dripping on the servo computer system on the lower layer when removing the servo computer system is a technical problem that needs to be solved urgently. Summary of the invention

[0005] The object of the present invention is to provide a connector and a network device to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a connector, comprising two connecting tubes correspondingly connected to the inlet and outlet of a servo computer system, and two connecting components correspondingly and slidably plugged in and sealed with the two connecting tubes, the connecting components comprising a fixedly arranged adapter block, the adapter block having a connected liquid flow channel and a plug hole, the connecting tube being plugged in the plug hole and connected with the liquid flow channel through the opening, a movable tube abutting against and coaxial with the connecting tube being elastically and slidably plugged in the plug hole, and a sealed cavity being formed in the plug hole located on the side of the movable tube away from the connecting tube; A central column fixedly connected to the adapter block is inserted in a sealing and sliding manner in the movable tube, and an end of the central column close to the connecting tube is connected to a suction ball through a suction tube, and the suction ball is located in the inner cavity of the connecting tube; The suction ball is provided with a suction port that abuts against the bottom of the inner cavity of the connecting tube, the central core column is provided with a drainage channel, and the suction port is connected to the sealing cavity through the inner cavity of the suction tube and the drainage channel in sequence; In the process of pulling the connecting tube outward to separate it from the corresponding connecting assembly, the movable tube is driven to slide elastically toward the connecting tube. The sliding of the movable tube blocks the opening while driving negative pressure to be generated in the sealed cavity so that the liquid in the connecting tube is sucked into the sealed cavity by the suction port for storage.

[0007] 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.

[0008] In the above connector, the straw is elastic.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] The above connector, the cylinder body includes an upper cylinder and a lower cylinder which are coaxially connected and fixedly connected to the fixed rod, the upper cylinder is located above the fixed rod, the lower cylinder is located below the fixed rod, and the lower cylinder is connected to the vent hole through a branch pipe.

[0014] In the above connector, two baffles are fixedly mounted on the rotating rod and are arranged opposite to each other and abut against the ball head of the spherical top rod. The two baffles cover part of the slide groove so that the ball head of the spherical top rod can slide and be engaged in the slide groove.

[0015] The network device includes the above-mentioned connector and a rack, wherein the inner wall of the rack is fixedly mounted with multiple groups of support plates arranged relatively up and down, each group of the support plates is used to support a servo computer system, and when the bottom of the servo computer system is in contact with the top of the support plate, the connecting pipe is coaxial with the corresponding sealing cavity.

[0016] Beneficial effects: 1. In the above technical scheme, the connector and network device provided by the present invention, through the design of the connecting component, utilize the elastic sliding of the movable tube and the sealed sliding plug-in between the central column and the movable tube, so that the movable tube can be driven to slide elastically during the separation of the connecting tube from the connecting component. The sliding of the movable tube blocks the opening so that the liquid does not flow out of the connecting component, and drives the negative pressure in the sealed cavity so that the liquid in the connecting tube is sucked into the sealed cavity by the suction port for storage, thereby greatly reducing the amount of liquid in the connecting tube, so that after the connecting tube is separated from the connecting component, the liquid in the inner cavity of the connecting tube is not easy to flow out and drip onto the servo computer system of the lower layer. At the same time, part of the liquid in the connecting component is blocked by the movable tube in the liquid flow channel, and part is stored in the sealed cavity, the drainage channel and the inner cavity of the suction tube, so that the liquid is not easy to flow out from the connecting component and drip onto the servo computer system of the lower layer. It can be seen that the movable tube can not only achieve the blocking of the connecting component during the sliding process, but also can prevent the liquid from flowing out and dripping onto the servo computer system of the lower layer after the connecting tube is separated from the connecting component, which can effectively solve the shortcomings of the prior art; 2. The present invention further improves the structure of the connecting tube and utilizes the clever coordination between the suction ball and the movable tube, so that when the connecting tube is removed, the liquid in its inner cavity can not only be further reduced by flowing into the movable tube, but also the further reduced liquid in the connecting tube can be blocked by the suction ball when flowing into the inner cavity of the movable tube and cannot flow out and drip, thereby better solving the technical problem of liquid flowing out and dripping at the connection when disassembling the servo computer system. Moreover, the existence of the suction ball enables the suction ball to not only absorb the liquid in the inner cavity of the connecting tube, but also block the port of the movable tube, so that the liquid in the movable tube cannot flow out and drip, producing unexpected technical effects; 3. In the present invention, when the two rotating rods are rotated to release the limit on the locking plate, the rotating rotating rods can also drive the inflatable member to inflate the airbag so that the airbag blocks the liquid flow channel, thereby achieving that the liquid will not flow into the inner cavity of the connecting tube during the process of the opening and the liquid flow channel being misaligned, which is more conducive to the discharge of the liquid in the inner cavity of the connecting tube before the connecting tube is completely removed from the socket. It can be seen that the rotating rod not only releases the limit on the locking plate, but also has an unexpected technical effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] First embodiment: like Figure 1-13 As shown, a connector provided by an embodiment of the present invention comprises two connecting tubes 402 which are connected to an inlet 4012 and an outlet 4013 of a servo computer system 4 in a one-to-one correspondence, and two connecting components which are sealed and slidably plugged in with the two connecting tubes 402 in a one-to-one correspondence, wherein the connecting component comprises a fixedly arranged adapter block 5, wherein a connected liquid flow channel 501 and a plug hole are provided in the adapter block 5, wherein the connecting tube 402 is plugged in the plug hole and is connected to the liquid flow channel 501 through an opening 4021, wherein an active tube 23 which is in contact with and coaxial with the connecting tube 402 is elastically and slidably plugged in the plug hole, and a sealed cavity 502 is formed in the plug hole located at a side of the active tube 23 away from the connecting tube 402; A central column 22 fixedly connected to the adapter block 5 is inserted and sealed in the movable tube 23 for sliding movement. An end of the central column 22 close to the connecting tube 402 is connected to a suction ball 20 through a suction tube 21. The suction ball 20 is located in the inner cavity of the connecting tube 402. A suction port 2001 is provided in the suction ball 20 to abut against the bottom of the inner cavity of the connecting tube 402, a drainage channel 2201 is provided in the central core column 22, and the suction port 2001 is connected to the sealing cavity 502 through the inner cavity of the suction tube 21 and the drainage channel 2201 in sequence; In the process of pulling the connecting tube 402 outward to separate it from the corresponding connecting component, the movable tube 23 is driven to slide elastically toward the connecting tube 402. The sliding of the movable tube 23 blocks the opening 4021 while driving negative pressure to be generated in the sealed cavity 502 so that the liquid in the connecting tube 402 is sucked into the sealed cavity 502 by the suction port 2001 for storage.

[0022] The connector provided in this embodiment is used to seal and 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 circuit. The words related to directions and positions involved in the present invention are relative to the 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, and two inner channels 4014 corresponding to the inlet 4012 and the outlet 4013 are also opened in the locking plate 401. The two inner channels 4014 are connected to two ports of the liquid channel inside the servo computer system 4 in a one-to-one manner. 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, and the two connecting pipes 402 are connected to the inlet 4012 and the outlet 4013 in a one-to-one manner. The two connecting pipes 402 are plugged into the adapter blocks 5 in the two connecting components in a one-to-one manner. The present invention further includes a first liquid manifold 2 and a second liquid manifold 3 arranged opposite to each other, wherein one connecting assembly is fixedly mounted on the first liquid manifold 2, and the other connecting assembly is fixedly mounted on the second liquid manifold 3, the first liquid manifold 2 is connected to a liquid supply mechanism (not shown in the figure) that provides liquid, and the first liquid manifold 2 is connected to a transfer block 5 in one of the connecting assemblies through a connecting pipe 19, the cold liquid flows from the first liquid manifold 2 through the connecting pipe 19 into the transfer block 5, and then flows through the transfer block 5 into the corresponding connecting pipe 402, and then flows into the liquid channel in the servo computer system 4 through the inlet 4012 and the inner channel 4014 to cool the servo computer system 4 The second liquid manifold 3 is connected to the adapter block 5 in another connecting assembly through another connecting pipe 19. After the cold liquid after cooling the servo computer system 4 becomes hot liquid, the hot liquid flows into another connecting pipe 402 through another inner channel 4014 and outlet 4013, and then flows into another adapter block 5, and then flows into the second liquid manifold 3 through another connecting pipe 19 to be discharged, thereby forming a cycle. In the present invention, there are multiple servo computer systems 4, and the multiple servo computer systems 4 are arranged up and down. Each servo computer system 4 is equipped with two connecting assemblies, and the cold liquid flowing out of the first liquid manifold 2 will be supplied to multiple servo computer systems 4 at the same time. The liquid flow channel 501 opened in the adapter block 5 is connected to the connecting pipe 19, and the socket opened in the adapter block 5 is used for the sealing and sliding insertion of the connecting pipe 402. The two connecting pipes 402 on the servo computer system 4 correspond to the sockets in the two adapter blocks 5 in a one-to-one sealing and sliding plug-in. The connecting tube 402 is provided with an opening 4021 , which is connected to the inner cavity of the connecting tube 402 . When the servo computer system 4 is installed, the opening 4021 is connected to the liquid channel 501 , so that the liquid channel 501 is connected to the inner cavity of the connecting tube 402 .An active tube 23 that is in contact with and coaxial with the connecting tube 402 is elastically and sealingly inserted in 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 slidable, the volume of the sealed cavity 502 changes when the active tube 23 slides.

[0023] 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.

[0024] 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.

[0025] It can be seen that the present invention, through the design of the connecting assembly, utilizes the elastic sliding of the movable tube 23 and the sealed sliding plug-in between the central column 22 and the movable tube 23, so that the movable tube 23 can be driven to elastically slide during the separation of the connecting tube 402 from the connecting assembly. The sliding of the movable tube 23 blocks the opening 4021 so that the liquid does not flow out of the connecting assembly, and drives the negative pressure in the sealed cavity 502 so that the liquid in the connecting tube 402 is sucked into the sealed cavity 502 by the suction port 2001 for storage, thereby greatly reducing the amount of liquid in the connecting tube 402, so that the connecting assembly After the connecting pipe 402 is separated from the connecting assembly, the liquid in the inner cavity of the connecting pipe 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 assembly is blocked in the liquid flow channel 501 by the movable tube 23, and part of it is stored in the sealing cavity 502, the drainage channel 2201 and the inner cavity of the straw 21. Therefore, the liquid is not easy to flow out of the connecting assembly and drip onto the servo computer system 4 at the lower layer. The movable tube 23 produces at least two different technical effects during the sliding process, and can effectively solve the shortcomings of the prior art.

[0026] Furthermore, the bottom of the inner cavity of the connecting tube 402 is tilted downward toward the direction of the movable tube 23 so that part of the liquid in its inner cavity passes over the suction ball 20 and flows into the movable tube 23 during the movement of the connecting tube 402. When the connecting tube 402 is separated from the connecting assembly, 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 for the suction port 2001 to completely absorb the liquid in the inner cavity of the connecting tube 402, in order to further reduce the liquid in the connecting tube 402, in the present invention, the bottom heights of the ports where the inner cavity of the connecting tube 402 and the inner cavity of the movable tube 23 are abutted are the same, and based on the fact that the bottom of the inner cavity of the connecting tube 402 is tilted downward toward the movable tube 23, the liquid in the connecting tube 402 can also flow into the inner cavity of the movable tube 23 along the bottom of its inner cavity during the process of being sucked by the suction port 2001, and thus the liquid in the inner cavity of the connecting tube 402 is further reduced, so that it is difficult for the liquid in the inner cavity of the connecting tube 402 to flow out and drip when the connecting tube 402 is separated from the connecting 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 connecting component, the liquid entering the inner cavity of the movable tube 23 cannot flow out, so that the liquid in the connecting component is also difficult to flow out and drip.

[0027] It can be seen that, in the present invention, by further improving the structure of the connecting tube 402 and utilizing the clever cooperation between the suction ball 20 and the movable tube 23, the liquid in the inner cavity of the connecting tube 402 can not only be further reduced by flowing into the movable tube 23 when the connecting tube 402 is removed, but also the liquid further reduced in the connecting tube 402 can be blocked by the suction ball 20 when flowing into the inner cavity of the movable tube 23 and cannot flow out and drip, thereby better solving the technical problem of liquid flowing out and dripping at the connection when disassembling the servo computer system 4. Moreover, the existence of the suction ball 20 enables the suction ball 20 to not only absorb the liquid in the inner cavity of the connecting tube 402, but also block the port of the movable tube 23, so that the liquid in the movable tube 23 cannot flow out and drip, producing an unexpected technical effect.

[0028] Among them, the straw 21 is elastic and can deform elastically in the radial reverse direction, so that the suction port 2001 can always abut against the bottom of the inner cavity of the connecting tube 402 during the movement of the connecting tube 402, and it is also beneficial for the suction ball 20 to better enter the connecting tube 402 when the connecting tube 402 is inserted into the socket in the adapter block 5.

[0029] In this embodiment, the connector also includes two locking members 6 fixedly connected to the two adapter blocks 5 in a one-to-one correspondence. The servo computer system 4 includes a locking plate 401 fixedly connected thereto. The locking plate 401 is provided with two locking holes 4011 that match the two locking members 6 in a one-to-one correspondence. When the connecting tube 402 is inserted into a specific position in the socket, the locking member 6 locks the locking plate 401 so that the connecting tube 402 is locked in the connecting assembly. Specifically, a compression spring 24 is installed between the movable tube 23 and the inner wall of the sealed cavity 502. The compression spring 24 is always in a compressed state. The elastic sliding of the movable tube 23 is achieved based on the compression elastic force of the compression spring 24. When the connecting tube 402 is inserted into the corresponding socket, the movable tube 23 is pushed to slide toward the sealed cavity 502 so that the compression spring 24 is continuously compressed. Under the action of the elastic force of the compression spring 24, the connecting tube 402 is subjected to a force away from the sealed cavity 502, so that the connecting tube 402 is easily detached from the connecting assembly. For this reason, in the present invention, by adding a setting of a locking member 6, after the connecting tube 402 is inserted into a specific position in the socket, the locking member 6 can lock the locking plate 401. Since the locking plate 401 and the connecting tube 402 are both fixedly connected to the servo computer system 4, the connecting tube 402 is also locked after the locking plate 401 is locked, so that the connecting tube 402 is located in the socket and will not slide out.

[0030] Among them, the locking member 6 includes a fixed rod 9 fixedly plugged with the adapter block 5, and two symmetrically arranged rotating rods 7 are elastically rotatably provided on the fixed rod 9. An abutment plate 12 that abuts and cooperates with the two rotating rods 7 is fixedly installed at one end of the fixed rod 9 away from the adapter block 5. In the initial state, the two rotating rods 7 abut against the abutment plate 12 so that the abutment plate 12 can limit the two rotating rods 7. During the insertion of the connecting tube 402 into the sealing cavity 502, the inner wall of the locking hole 4011 and the outer side surfaces of the two rotating rods 7 slide and squeeze to push the two rotating rods 7 to rotate toward the fixed 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 abutment 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 is connected to the liquid flow channel 501. Specifically, a return spring 10 is fixedly connected between the two rotating rods 7 and the fixed rod 9, and the rotational connection between the rotating rod 7 and the fixed rod 9 is achieved 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 is not repeated here. A pair of support plates 11 are fixedly installed at the end of the fixed rod 9, and a rotating shaft 8 is rotatably provided on the support plate 11, which is plugged in one by one with the two 7. One end of the rotating rod 7 is rotationally connected to the fixed rod 9 through the rotating shaft 8, and the other end is used to abut against the side of the locking plate 401 to achieve the limitation of the locking plate 401.

[0031] 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 contact 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.

[0032] 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.

[0033] 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.

[0034] Among them, the cylinder body includes an upper cylinder 13 and a lower cylinder 16 which are coaxially connected and fixedly connected to the fixed rod 9. The upper cylinder 13 is located above the fixed rod 9, and the lower cylinder 16 is located below the fixed rod 9. The inner cavity diameters of the upper cylinder 13 and the lower cylinder 16 are the same, and the lower cylinder 16 is connected to the vent 901 through a branch pipe 17.

[0035] Two baffles 702 arranged opposite to each other and abutting against the ball head of the spherical top rod 15 are fixedly mounted on the rotating rod 7 . The two baffles 702 partially block the slide groove 701 so that the ball head of the spherical top rod 15 can slide and be engaged in the slide groove 701 .

[0036] Second embodiment: like Figure 1-13 As shown, a network device provided by an embodiment of the present invention includes the above-mentioned connector and a rack 1. The inner wall of the rack 1 is fixedly mounted with multiple groups of support plates 25 arranged opposite to each other up and down. 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 in contact with the top of the support plate 25, the connecting pipe 402 is coaxial with the corresponding sealed cavity 502. The rack 1 is used to accommodate the servo computer system 4. The support plate 25 is used to support the servo computer system 4. There are multiple servo computer systems 4, which are arranged up and down. When the servo computer system 4 needs to be installed on the rack 1, the bottom of the servo computer system 4 is in contact with the top of the support plate 25, and then the servo computer system 4 is directly pushed toward the inside of the rack 1 so that the two connecting pipes 402 on the servo computer system 4 are inserted into the corresponding sealed cavity 502.

[0037] Among them, the frame 1 is fixedly installed with a first liquid manifold 2 and a second liquid manifold 3 arranged opposite to each other. The first liquid manifold 2 and the second liquid manifold 3 are used to provide channels for liquid. When working, the first liquid manifold 2 is connected to a liquid supply mechanism for providing liquid (not shown in the figure), and the first liquid manifold 2 is connected to the adapter block 5 in one of the connecting components through a connecting pipe 19. Cold liquid flows from the first liquid manifold 2 through the connecting pipe 19 into the adapter block 5, and then flows into the corresponding connecting pipe 402 through the adapter block 5, and then flows into the liquid channel in the servo computer system 4 through the inlet 4012 and the inner channel 4014 to cool the servo computer system 4; the second liquid manifold 3 is connected to the adapter block 5 in another connecting component through another connecting pipe 19. After cooling the servo computer system 4, the cold liquid becomes hot liquid. The hot liquid flows into another connecting pipe 402 through another inner channel 4014 and the outlet 4013, and then flows into another adapter block 5, and then flows into the second liquid manifold 3 through another connecting pipe 19 for discharge.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
