Description

Technical Field

[0001] This application relates to the technical field of connectors, and more specifically, to a connector and a liquid cooling system. Background Art

[0002] In the related art, as an important component in a liquid cooling system, a fluid connector mainly functions to quickly connect and disconnect fluid passages such as pipelines and cold plates, facilitating equipment debugging and maintenance, especially in situations where the equipment needs to be disassembled, assembled, and debugged multiple times. The existing fluid connectors use a ball structure for locking. When high-pressure fluid flows through the fluid connector, since the contact between the ball and the plug is a point contact, under the action of the high-pressure fluid pressure, the force application point of the ball is prone to deformation, resulting in wear or crushing on the surface of the ball, thereby reducing the connection stability and working life of the fluid connector. Summary of the Utility Model

[0003] Embodiments of this application provide a connector and a liquid cooling system to solve or improve the technical problem that when high-pressure fluid passes through the connector, the connector is easily damaged under the action of the high-pressure fluid, thereby reducing the connection stability and working life of the fluid connector.

[0004] A connector according to an embodiment of this application includes a plug and a sleeve. Among them, the plug includes a locking portion; the sleeve includes a roller and a first valve body. The first valve body is provided with a receiving cavity, the roller is rotatably provided on the first valve body, and a part of the roller is located in the receiving cavity; when the plug is inserted into the receiving cavity, the roller abuts against the locking portion to lock the plug in the sleeve.

[0005] In this way, by using the roller to abut against the locking portion to lock the plug in the sleeve, the contact between the plug and the sleeve is a line contact. Under high-pressure fluid conditions, the line contact can, to a certain extent, prevent wear or crushing on the surface of the roller, thereby improving the connection stability and working life of the fluid connector.

[0006] In some embodiments, the sleeve includes a first elastic member and a sleeve body. The first elastic member connects the first valve body and the sleeve body, and the first elastic member is configured to abut against the first valve body and the sleeve body when the plug is inserted into the receiving cavity.

[0007] In this way, when the plug is inserted into the receiving cavity, by the first elastic member abutting against the first valve body and the sleeve body, the first elastic member can transfer the force required for reset to the valve body, and the valve body can transfer the force to the roller, making the roller fixed.

[0008] In some embodiments, the sleeve includes a movement locking ring and a second elastic member. A boss is formed on the inner wall of the movement locking ring. The second elastic member connects the movement locking ring and the sleeve body. The boss abuts against the roller, and the second elastic member is configured to abut against the movement locking ring and the sleeve body when the plug is inserted into the receiving cavity.

[0009] Thus, when the plug is inserted into the receiving cavity, the second elastic member abuts against the movement locking ring and the sleeve body, so that the second elastic member can transfer the force required for resetting to the movement locking ring, and the boss on the movement locking ring can abut against the roller, thereby transferring the force to the roller through the boss to fix the roller.

[0010] In some embodiments, the sleeve further includes an unlocking member connected to the movement locking ring. The unlocking member is configured to drive the movement locking ring to move back and forth between an unlocking position and a locking position. When the movement locking ring is in the locking position, the boss abuts against the roller so that the roller abuts against the locking portion. When the movement locking ring is in the unlocking position, the boss releases the abutment on the roller so that the roller releases the abutment on the locking portion.

[0011] Thus, by providing an unlocking member on the sleeve and enabling the unlocking member to move back and forth between the unlocking position and the locking position, the plug can be fixed when the unlocking member moves to the locking position when the plug is inserted into the sleeve, and the plug can be unlocked when the unlocking member moves to the unlocking position when the plug needs to be withdrawn from the sleeve.

[0012] In some embodiments, a convex portion is provided at one end of the unlocking member. The convex portion is movably connected to the sleeve body. When the movement locking ring is in the locking position, the convex portion abuts against the sleeve body. When the movement locking ring is in the unlocking position, the convex portion is separated from the sleeve body.

[0013] Thus, by providing a convex portion at one end of the unlocking member, when the movement locking ring is in the locking position, the convex portion can abut against the sleeve body under the action of the second elastic member to fix the plug; when the movement locking ring is in the unlocking position, the second elastic member can be compressed so that the convex portion is separated from the sleeve body to unlock the plug.

[0014] In some embodiments, the sleeve includes a valve seat and a first sealing member. The valve seat is provided with a first accommodating cavity. A part of the sleeve body extends into the first accommodating cavity. The first sealing member is disposed between the valve seat and the sleeve body. The valve seat is fixedly connected to the sleeve body and is used for connecting a pipeline.

[0015] Thus, by providing a first accommodation cavity in the valve seat, the valve seat and a part of the sleeve body located within the first accommodation cavity are fixedly connected, so that the sleeve body can be fixed. By providing a first seal between the valve seat and the sleeve body, the gap between the sleeve body and the valve seat can be sealed, preventing fluid from flowing onto other components of the fluid passage sleeve.

[0016] In some embodiments, a limiting portion is provided on the outer side of the valve seat, and the limiting portion is configured to limit the unlocking member during the movement of the unlocking member to unlock the locking portion, so that the moving locking ring is located at the unlocking position.

[0017] Thus, by providing a limiting portion on the valve seat, the unlocking member can be limited to accurately determine the unlocking position of the unlocking member.

[0018] In some embodiments, the sleeve includes a sleeve body, a thimble, a first piston, and a third elastic member. The sleeve body is provided with a second accommodation cavity, which communicates with the first accommodation cavity. The thimble, the first piston, and the third elastic member are disposed within the second accommodation cavity. The thimble passes through the first piston, and the first piston is provided with a first flow channel. The third elastic member connects the first piston and the thimble. When the plug passes through the first accommodation cavity, the plug abuts against the first piston, causing the first piston to compress the third elastic member, and the end of the thimble away from the third elastic member opens the first flow channel.

[0019] Thus, when the plug passes through the first accommodation cavity, by providing a second accommodation cavity within the sleeve body, the thimble, the first piston, and the third elastic member can be disposed within the second accommodation cavity, and the second accommodation cavity communicates with the receiving cavity. Therefore, when the plug is inserted into the second accommodation cavity, the plug can abut against the first piston, causing the first piston to compress the third elastic member, and further causing the end of the thimble away from the third elastic member to open the first flow channel, allowing fluid to flow through.

[0020] In some embodiments, when the roller releases the abutment against the locking portion, the third elastic member is configured to drive the first piston to squeeze the plug, so that the plug exits the receiving cavity, and the end of the thimble away from the third elastic member is connected to the first piston to close the first flow channel.

[0021] Thus, when it is necessary to unlock the plug, by transmitting the force provided by resetting the third elastic member to the first piston, the first piston can be caused to squeeze the plug, quickly extruding the plug out of the receiving cavity, and the thimble can be reset and connected to the first piston, thereby closing the first flow channel.

[0022] In some embodiments, a second seal is provided on the outer side of the end of the thimble away from the third elastic member. When the plug exits the receiving cavity, the second seal connects the end of the thimble away from the third elastic member and the surface of the first piston facing the first flow channel, and / or;

[0023] The sleeve includes a third seal, which is provided on the surface of the sleeve body facing the second accommodating cavity. When the plug is inserted into the second accommodating cavity, the third seal connects the outer side of the plug and the surface of the sleeve body facing the second accommodating cavity.

[0024] In this way, by providing the second seal, the first flow channel can be sealed when the plug is not inserted into the sleeve or the plug exits the sleeve. By providing the third seal, the gap between the plug and the sleeve body can be sealed to prevent the fluid from flowing onto other components.

[0025] In some embodiments, the plug includes a second valve body, a second piston, a fourth elastic member, and a plug snap ring. The second valve body is provided with a third accommodating cavity, and the second piston, the fourth elastic member, and the plug snap ring are arranged in the third accommodating cavity. The second piston is provided with a second flow channel, and the fourth elastic member connects the second piston and the plug snap ring. When the plug passes through the receiving cavity, the thimble abuts against the second piston to compress the third elastic member by the second piston, and the end of the second piston away from the second valve body opens the second flow channel.

[0026] In this way, when the plug passes through the first accommodating cavity, by providing the third accommodating cavity in the second valve body, the second piston, the fourth elastic member, and the plug snap ring can be arranged in the third accommodating cavity. Thus, when the plug is inserted into the second accommodating cavity, the thimble can abut against the second piston to compress the fourth elastic member to open the first flow channel so that the fluid can flow through.

[0027] In some embodiments, a fourth seal is provided on the outer side of the end of the second piston away from the fourth elastic member. When the plug exits the receiving cavity, the fourth seal connects the end of the second piston away from the fourth elastic member and the surface of the second valve body facing the second flow channel.

[0028] In this way, by providing the fourth seal, the second flow channel can be sealed when the plug is not inserted into the sleeve or the plug exits the sleeve.

[0050] The present disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, components and settings of specific examples are described herein. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or reference letters in different examples.

In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0051] In the related art, the existing connector uses a ball structure for locking. When the plug is inserted into the sleeve, the plug is fixed by squeezing the ball. When high-pressure fluid flows through the fluid connector, since the contact between the ball and the plug is point contact, under the action of the high-pressure fluid pressure, the force application point of the ball is prone to deformation, resulting in wear or crushing on the surface of the ball, thereby reducing the connection stability and working life of the fluid connector.

[0052] To solve the above technical problems, an embodiment of the present application provides a connector 100.

[0053] Please refer to Figure 1 and Figure 2 , a connector 100 according to an embodiment of the present application includes a plug 13 and a sleeve 11. Among them, the plug 13 includes a locking portion 131; the sleeve 11 includes a roller 111 and a first valve body 112. The first valve body 112 is provided with a receiving cavity 1121. The roller 111 is rotatably provided on the first valve body 112, and a part of the roller 111 is located in the receiving cavity 1121; when the plug 13 is inserted into the receiving cavity 1121, the roller 111 abuts against the locking portion 131 to lock the plug 13 in the sleeve 11.

[0054] In this way, the roller 111 is used to press the locking portion 131 to lock the plug 13 in the sleeve 11, so that the contact between the plug 13 and the sleeve 11 is line contact. Under high-pressure fluid conditions, the line contact can avoid wear or crushing on the surface of the roller 111 to a certain extent, thereby improving the connection stability and service life of the fluid connector 100.

[0055] Among them, the connector 100 is an important component of the liquid cooling system (not shown in the figure). Its main function is to realize the rapid opening and closing of the fluid passages such as pipelines and cold plates, which is convenient for equipment debugging and maintenance, especially in occasions where the equipment needs to be disassembled and debugged many times. For example, the connector 100 can be used to connect the liquid cooling system and the server. When the server needs to dissipate heat, the water pipe of the liquid cooling system and the water pipe on the server are connected through the connector 100, so that the low-temperature fluid in the liquid cooling system flows into the server to absorb heat and cool down.

[0056] Specifically, the connector 100 includes a plug 13 and a sleeve 11. The plug 13 can be inserted into and withdrawn from the sleeve 11. When the plug 13 is inserted into the sleeve 11, the connector 100 can be locked to allow fluid to flow through the connector 100; when the plug 13 is withdrawn from the sleeve 11, the connector 100 can be separated to prohibit the fluid from flowing through the connector 100.

[0057] The shape of the plug 13 can be adapted to the shape of the sleeve 11. For example, when the shape of the sleeve 11 is cylindrical, the shape of the plug 13 is cylindrical and the diameter of the sleeve 11 is larger than the diameter of the plug 13. The plug 13 includes a locking portion 131, which is formed on the outer wall of the plug 13 and is approximately shaped like a prism. The locking portion 131 can be used to lock the plug 13 when the plug 13 is inserted into the sleeve 11.

[0058] The sleeve 11 includes a roller 111 and a first valve body 112. The roller 111 is arranged on the first valve body 112, so that the first valve body 112 can provide support for the movement of the roller 111. The roller 111 is cylindrical in shape, and the first valve body 112 is provided with a receiving cavity 1121, so that when the roller 111 passes through the first valve body 112, the roller 111 can be partially located in the receiving cavity 1121, so that the roller 111 can roll in the receiving cavity 1121.

[0059] When the plug 13 is inserted into the accommodating cavity 1121 of the first valve body 112 , the roller 111 can abut against the edge surface of the locking portion 131 , so that the plug 13 is fixed by the force transmitted by the locking portion 131 , and the plug 13 can be locked in the sleeve 11 .

[0060] See also Figures 3 to 7, in some embodiments, the sleeve 11 includes a first elastic member 113 and a sleeve body 114. The first elastic member 113 connects the first valve body 112 and the sleeve body 114, and the first elastic member 113 is configured to abut against the first valve body 112 and the sleeve body 114 when the plug 13 is inserted into the receiving cavity 1121.

[0061] Thus, when the plug 13 is inserted into the receiving cavity 1121, the first elastic member 113 abuts against the first valve body 112 and the sleeve body 114, so that the first elastic member 113 can transmit the force required for resetting to the valve body, and the valve body can transmit the force to the roller 111, making the roller 111 fixed.

[0062] Specifically, the sleeve 11 further includes a first elastic member 113 and a sleeve body 114. Among them, the first elastic member 113 can be an elastic spring, such as a helical spring and a rubber spring. The first elastic member 113 can connect the first valve body 112 and the sleeve body 114. The sleeve body 114 is fixed in the sleeve 11 and the sleeve body 114 is a hollow ring. Thus, the first elastic member 113 can be compressed or reset according to the movement of the first valve body 112.

[0063] When the plug 13 is inserted into the receiving cavity 1121 of the sleeve 11, the locking portion 131 presses the roller 111, so that the roller 111 can transmit the force to the first valve body 112, causing the first valve body 112 to move axially. Thus, the first valve body 112 can press the first elastic member 113, causing the first elastic member 113 to be compressed. Further, the first elastic member 113 can abut against the sleeve body 114, and the force generated under the tendency of the first elastic member 113 to reset can be transmitted to the first valve body 112, making the first valve body 112 abutted by the first elastic member 113.

[0064] Please refer to Figures 3 to 7 , in some embodiments, the sleeve 11 includes a moving lock ring 115 and a second elastic member 116. A boss 1151 is formed on the inner wall of the moving lock ring 115. The second elastic member 116 connects the moving lock ring 115 and the sleeve body 114. The boss 1151 abuts against the roller 111, and the second elastic member 116 is configured to abut against the moving lock ring 115 and the sleeve body 114 when the plug 13 is inserted into the receiving cavity 1121.

[0065] Thus, when the plug 13 is inserted into the receiving cavity 1121, the second elastic member 116 abuts against the moving lock ring 115 and the sleeve body 114, so that the second elastic member 116 can transmit the force required for resetting to the moving lock ring 115, and the boss 1151 on the moving lock ring 115 can abut against the roller 111, thereby transmitting the force to the roller 111 through the boss 1151, making the roller 111 fixed.

[0066] Specifically, the sleeve 11 further includes a movement locking ring 115 and a second elastic member 116. Among them, the movement locking ring 115 is in the shape of a circular ring and is sleeved on the first valve body 112. A boss 1151 is formed on the inner wall of the movement locking ring 115. The shape of the boss 1151 can be a frustum of a cone or a frustum of a pyramid, and the movement locking ring 115 can be abutted against the roller 111 through the boss 1151. The second elastic member 116 can be an elastic spring, such as a helical spring and a rubber spring. The second elastic member 116 can connect the movement locking ring 115 and the sleeve body 114, so that the first elastic member 113 can be compressed or reset according to the movement of the movement locking ring 115.

[0067] When the plug 13 is inserted into the receiving cavity 1121 of the sleeve 11, since the sleeve body 114 is fixed, the movement locking ring 115 is abutted by the acting force generated by the reset of the second elastic member 116, so that the roller 111 can move from the side surface of the boss 1151 to the upper top surface of the boss 1151, and further the roller 111 is fixed by the radial force of the boss 1151.

[0068] Please refer to Figures 3 to 10 , in some embodiments, the sleeve 11 further includes an unlocking member 117. The unlocking member 117 is connected to the movement locking ring 115 and is configured to drive the movement locking ring 115 to move back and forth between an unlocking position and a locking position. When the movement locking ring 115 is in the locking position, the boss 1151 abuts against the roller 111 so that the roller 111 abuts against the locking portion 131. When the movement locking ring 115 is in the unlocking position, the boss 1151 releases the abutment against the roller 111 so that the roller 111 releases the abutment against the locking portion 131.

[0069] In this way, by providing the unlocking member 117 on the sleeve 11 and enabling the unlocking member 117 to move back and forth between the unlocking position and the locking position, the unlocking member 117 can move to the locking position to fix the plug 13 when the plug 13 is inserted into the sleeve 11, and the unlocking member 117 can move to the unlocking position to unlock the plug 13 when the plug 13 needs to be withdrawn from the sleeve 11.

[0070] Specifically, the sleeve 11 further includes an unlocking member 117. The unlocking member 117 can be used to unlock the plug 13 and the sleeve 11, so that the connector 100 is separated. Among them, the unlocking member 117 can be fixedly connected to the movement locking ring 115, and the unlocking key moves on the sleeve 11. The moving unlocking member 117 can drive the movement locking ring 115 to move back and forth between the unlocking position and the locking position. The unlocking position is the position where the movement locking ring 115 and the unlocking member 117 are located when unlocking the plug 13 and the sleeve 11, and the locking position is the position where the movement locking ring 115 and the unlocking member 117 are located when locking the plug 13 and the sleeve 11.

[0071] When the moving locking ring 115 is in the locked position, the second elastic member 116 can abut against the moving locking ring 115 to drive the upper top surface of the boss 1151 to abut against the roller 111, so that the roller 111 abuts against the side surface of the locking portion 131.

[0072] When the moving locking ring 115 is in the unlocked position, the unlocking member 117 can drive the moving locking ring 115 to squeeze the second elastic member 116, so that the second elastic member 116 is compressed to abut against the sleeve body 114, and the moving locking ring 115 moves, which can drive the roller 111 to move from the fixed surface of the boss 1151 to the side surface of the boss 1151, so that the boss 1151 is separated from the roller 111, so that the roller 111 is released from the abutment of the locking portion 131, and the plug 13 can be separated from the sleeve 11.

[0073] Please refer to Figures 3 to 10 , in some embodiments, a convex portion 1171 is provided at one end of the unlocking member 117, and the convex portion 1171 is movably connected to the sleeve body 114. When the moving locking ring 115 is in the locked position, the convex portion 1171 abuts against the sleeve body 114. When the moving locking ring 115 is in the unlocked position, the convex portion 1171 is separated from the sleeve body 114.

[0074] In this way, by providing the convex portion 1171 at one end of the unlocking member 117, when the moving locking ring 115 is in the locked position, the convex portion 1171 can abut against the sleeve body 114 under the action of the second elastic member 116, so as to fix the plug 13; when the moving locking ring 115 is in the unlocked position, the second elastic member 116 can be compressed so that the convex portion 1171 is separated from the sleeve body 114, so as to unlock the plug 13.

[0075] Specifically, a convex portion 1171 is provided at one end of the unlocking member 117 close to the sleeve body 114, and a part of the convex portion 1171 can be movably connected to the protruding part on the sleeve body 114.

[0076] For example, when the moving locking ring 115 is in the locked position, the convex portion 1171 can abut against the sleeve body 114, so that the acting force for resetting the second elastic member 116 can be transmitted to the moving locking ring 115, so that the moving locking ring 115 drives the convex portion 1171 of the unlocking member 117 to abut against the sleeve body 114, so that the unlocking member 117 is fixed.

[0077] For another example, when the moving locking ring 115 is in the unlocked position, the convex portion 1171 of the unlocking member 117 can be separated from the sleeve body 114, so that the unlocking member 117 can drive the moving locking ring 115 to move, so that the moving locking ring 115 can compress the second elastic member 116.

[0078] Please refer to Figure 4 In some embodiments, the sleeve 11 includes a valve seat 118 and a first seal 119. The valve seat 118 is provided with a first receiving cavity 1181. A part of the sleeve body 114 extends into the first receiving cavity 1181. The first seal 119 is disposed between the valve seat 118 and the sleeve body 114. The valve seat 118 is fixedly connected to the sleeve body 114 and is used to connect the pipeline.

[0089] When the plug 13 passes through the first accommodation cavity 1181 and the second accommodation cavity 1141, the plug 13 can abut against the first piston 122, so that the first piston 122 compresses the third elastic member 124, thereby enabling the ejector pin 121 to move away from the end of the third elastic member 124, so that the first flow channel 123 is opened, and thus the fluid can flow from the plug 13 into the first flow channel 123.

[0090] Please refer to Figures 8 to 10 , in some embodiments, when the roller 111 releases the abutment of the locking portion 131, the third elastic member 124 is configured to drive the first piston 122 to squeeze the plug 13, so that the plug 13 exits the accommodation cavity 1121, and the end of the ejector pin 121 away from the third elastic member 124 is connected to the first piston 122 to close the first flow channel 123.

[0091] In this way, when it is necessary to unlock the plug 13, by transmitting the acting force provided by resetting the third elastic member 124 to the first piston 122, the first piston 122 can be made to squeeze the plug 13, quickly extruding the plug 13 out of the accommodation cavity 1121, and the ejector pin 121 can be reset and connected to the first piston 122, so that the first flow channel 123 can be closed.

[0092] Specifically, when it is necessary to withdraw the plug 13 from the sleeve 11, the roller 111 can release the abutment of the locking portion 131. At this time, the third elastic member 124 can provide the acting force required for resetting to the first piston 122, and the first piston 122 can transmit the acting force to the plug 13, so that the plug 13 exits the second accommodation cavity 1141 and the accommodation cavity 1121, so that the plug 13 is separated from the sleeve 11. And when the first piston 122 is reset, the end of the ejector pin 121 away from the third elastic member 124 can be connected to the first piston 122, so that the first flow channel 123 is closed.

[0093] Please refer to Figures 5 to 10 , in some embodiments, a second seal 125 is provided on the outer side of the end of the ejector pin 121 away from the third elastic member 124.

When the plug 13 is inserted into the second accommodation cavity 1141, the third seal 126 connects the outer side of the plug 13 and the surface of the sleeve body 114 facing the second accommodation cavity 1141.

[0094] Thus, by providing the second seal 125, the first flow channel 123 can be sealed when the plug 13 is not inserted into the sleeve 11 or when the plug 13 is withdrawn from the sleeve 11. By providing the third seal 126, the gap between the plug 13 and the sleeve body 114 can be sealed to prevent fluid from flowing onto other components.

The fourth elastic member 135 connects the second piston 133 and the plug snap ring 136. When the plug 13 passes through the receiving cavity 1121, the ejector pin 121 abuts against the second piston 133 to compress the third elastic member 124 by the second piston 133, and the end of the second piston 133 remote from the second valve body 132 opens the second flow channel 134.

[0098] Thus, when the plug 13 passes through the first accommodating cavity 1181, by providing a third accommodating cavity 1321 in the second valve body 132, the second piston 133, the fourth elastic member 135, and the plug snap ring 136 can be arranged in the third accommodating cavity 1321. As a result, when the plug 13 is inserted into the second accommodating cavity 1141, the ejector pin 121 can abut against the second piston 133, so that the second piston 133 compresses the fourth elastic member 135 to open the first flow channel 123, allowing the fluid to flow through.

[0099] Specifically, the plug 13 further includes a second valve body 132, a second piston 133, a fourth elastic member 135, and a plug snap ring 136. Among them, the shape of the second valve body 132 is adapted to the shape of the sleeve 11, so that the second valve body 132 can sequentially enter the receiving cavity 1121 and the second accommodating cavity 1141.

The plug snap ring 136 is fixed on the plug seat 118 of the plug 13, so that the fourth elastic member 135 can abut against the plug snap ring 136 when compressed.

[0102] When the plug 13 extends into the sleeve 11 and passes through the second accommodating cavity 1141, the plug seat 118 of the plug 13 can abut against the first piston 122, so that the third elastic member 124 is compressed. Thus, during the movement of the plug 13 extending into the second accommodating cavity 1141, the ejector pin 121 can abut against the second piston 133, so that the second piston 133 can compress the third elastic member 124. As a result, the end of the second piston 133 away from the second valve body 132 is separated from the second valve body 132, so that the second flow channel 134 communicates with the first flow channel 123.
