Abstract

The application relates to a quick socket, a plug-in assembly, a refrigerating system and a server. The quick socket comprises a sleeve and a locking piece. The sleeve comprises a shell and a valve body. The shell is sleeved on the valve body. A plug-in cavity for inserting a plug is formed in the valve body. A guide hole communicating with the plug-in cavity is arranged on the valve body. At least one of the shell and the valve body forms a limiting part. The locking piece is movably arranged in the guide hole. The locking piece can move between an initial position and a pressing position. When the locking piece is in the initial position, one end of the locking piece is located in the plug-in cavity, used for blocking the plug from leaving the plug-in cavity, and the other end of the locking piece abuts against the limiting part. The limiting part can prevent the locking piece from moving to the plug-in cavity. When the locking piece moves to the pressing position towards the shell, the locking piece unlocks the plug, so that the plug can leave the plug-in cavity. The quick socket is simple in overall structure.

Description

Technical Field

[0001] This application relates to the field of quick-connect connectors, and more particularly to a quick-connect socket, a connector assembly, a cooling system, and a server. Background Technology

[0002] Quick-connect couplings have been widely used in fluid transportation fields such as refrigerant delivery and water transportation.

[0003] Quick-connect connectors generally include a plug and a socket for plugging in; the socket structure of quick-connect connectors in related technologies is relatively complex. Summary of the Invention

[0004] This application provides a quick-connect socket, which simplifies the structure of the quick-connect socket and at least partially solves the above-mentioned technical problems.

[0005] To achieve the above objectives, according to a first aspect of this application, a quick-connect socket is provided, comprising:

[0006] A sleeve includes a housing and a valve body, the housing being fitted onto the valve body, the valve body having a plug-in cavity for inserting a plug, the valve body having a guide hole communicating with the plug-in cavity, and at least one of the housing and the valve body forming a limiting portion;

[0007] A locking member is movably disposed in the guide hole. The locking member can move between an initial position and a pressing position. When the locking member is in the initial position, one end of the locking member is located in the insertion cavity to prevent the plug from leaving the insertion cavity. The other end of the locking member abuts against the limiting part, which can prevent the locking member from moving into the insertion cavity. When the locking member moves towards the outer shell to the pressing position, the locking member unlocks the plug so that the plug can leave the insertion cavity.

[0008] Optionally, the quick-connect socket further includes an elastic locking member disposed between the housing and the valve body. When the locking member is in the initial position, the elastic locking member applies an elastic force to the locking member to keep the locking member in the initial position. When the locking member is in the compressed position, the elastic locking member is compressed by the locking member and undergoes elastic deformation.

[0009] Optionally, the limiting portion includes a limiting block protruding from the inner wall surface of the housing. Along the axial direction of the valve body, the limiting block is located on the side of the locking member away from the elastic locking member. When the locking member is in the initial position, the limiting block abuts against the other end of the locking member to prevent the locking member from moving into the insertion cavity.

[0010] Optionally, along the axial direction of the valve body, a groove is formed on the side of the locking member away from the elastic locking member, and when the locking member is in the initial position, the limiting block is engaged in the groove.

[0011] Optionally, the housing may be movable relative to the valve body so that the limiting block moves the locking member from the initial position to the compression position.

[0012] Optionally, the locking member includes the connecting block and the main body, the connecting block is connected to one end of the main body, the other end of the main body passes through the guide hole, and the diameter of the connecting block is larger than the diameter of the guide hole;

[0013] The limiting portion includes a limiting surface formed on the outer surface of the valve body. When the locking member is in the initial position, the limiting surface abuts against the connecting block to prevent the locking member from moving into the insertion cavity.

[0014] Optionally, a protrusion is formed on the inner wall surface of the housing, and along the axial direction of the valve body, the protrusion is located on the side of the connecting block away from the elastic locking member, and the connecting block is located on the moving path of the protrusion;

[0015] The housing is movable relative to the valve body so that the protrusion moves the locking member from its initial position to the compression position.

[0016] Optionally, the guide hole extends from the inner wall of the valve body to the outer wall of the valve body and obliquely toward the elastic locking member.

[0017] According to a second aspect of this application, a plug assembly is also provided, including a plug and a quick-connect socket as described above, the plug being movable relative to the plug cavity.

[0018] Optionally, the plug includes a plug body and a mating part that are interconnected.

[0019] When the plug moves into the insertion cavity, the mating part is adapted to abut against the locking member and drive the locking member to move toward the outer shell;

[0020] When the plug is inserted into the socket, the locking member is in the initial position and abuts against the first side wall of the mating part facing out of the socket to prevent the mating part from moving.

[0021] Optionally, the mating portion includes a second sidewall facing the interior of the insertion cavity, and the second sidewall gradually slopes towards the center of the plug along its length.

[0022] As the plug moves into the insertion cavity, the second sidewall abuts against the locking member.

[0023] Optionally, the mating part further includes a plane, the plane connecting the first sidewall surface and the second sidewall surface.

[0024] As the plug moves into the insertion cavity, the locking member abuts against the second side wall and the plane in sequence.

[0025] Optionally, the plug further includes a first elastic element, one end of which is connected to the plug body. When the plug is inserted into the insertion cavity, the sleeve abuts against and squeezes the other end of the first elastic element.

[0026] Optionally, the sleeve includes a second elastic element, one end of which is connected to the valve body. When the plug is inserted into the insertion cavity, the plug abuts against and compresses the other end of the second elastic element.

[0027] According to a third aspect of this application, a refrigeration system is also provided, including the quick-connect socket or the plug assembly as described above.

[0028] According to a fourth aspect of this application, a server is also provided, including the cooling system described above.

[0029] In the quick-connect socket of this application embodiment, by movably setting the locking member within the guide hole and using a limiting part to limit the locking member, the locking member will not fall into the plug cavity in its initial state, thus simplifying the limiting structure of the locking member. When the plug is inserted or removed, the locking member is in a squeezed state, at which time the locking member does not affect the insertion and removal of the plug, and the plug can freely enter and exit the plug cavity; after the plug is inserted, the locking member switches from the squeezed state to the initial state, at which point the locking member is in the movement path of the plug, and the locking member can prevent the plug from leaving the plug cavity, thereby locking the plug, thus enabling quick plug-in and quick connection of the plug and the quick-connect socket, and the overall structure is simpler.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0047] According to the first aspect of this application, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This disclosure provides a quick-connect socket. The quick-connect socket includes a sleeve 1 and a locking member 2. The sleeve 1 includes a housing 11 and a valve body 12. The housing 11 is fitted onto the valve body 12. The valve body 12 has a insertion cavity 121 for inserting a plug 3. The valve body 12 has a guide hole 122 communicating with the insertion cavity 121. At least one of the housing 11 and the valve body 12 has a limiting portion 13. The locking member 2 is movably disposed in the guide hole 122. The locking member 2 can move between an initial position and a pressed position. When the locking member 2 is in the initial position, one end of the locking member 2 is located in the insertion cavity 121 to prevent the plug 3 from leaving the insertion cavity 121. The other end of the locking member 2 abuts against the limiting portion 13, which can prevent the locking member 2 from moving toward the insertion cavity 121. When the locking member 2 moves toward the housing 11 to the pressed position, the locking member 2 unlocks the plug 3, allowing the plug 3 to leave the insertion cavity 121.

[0048] It is understandable that the valve body 12 of the sleeve 1 has a plug cavity 121, so that the plug 3 can be inserted into the plug cavity 121 to achieve the cooperation between the plug 3 and the quick-connect socket.

[0049] When the plug 3 is inserted into the socket 121, the locking member 2 moves toward the outer shell 11 to the pressing position, so that the locking member 2 does not obstruct the plug 3, that is, the plug 3 can freely enter and exit the socket 121. When the plug 3 is inserted into the socket 121, that is, the plug 3 has been inserted into place, the locking member 2 is in the initial position. At this time, one end of the locking member 2 is located in the socket 121, and one end of the locking member 2 can prevent the plug 3 from leaving the socket 121, thereby locking the plug 3. At the same time, the limiting part 13 abuts against the other end of the locking member 2 to prevent the locking member 2 from moving further into the socket 121, thereby limiting the locking member 2. This allows the locking member 2 to both limit and lock the plug 3, and prevent it from falling completely into the socket 121, so that the locking member 2 can remain in the initial position.

[0050] When it is necessary to disengage the plug 3 from the socket cavity 121, the locking member 2 is placed in the pressed position, which unlocks the plug 3 and allows it to leave the socket cavity 121.

[0051] In other words, by movably positioning the locking member 2 within the guide hole 122 and limiting it using the limiting part 13, the locking member 2 will not fall into the insertion cavity 121 in its initial state, simplifying the limiting structure of the locking member 2. When the plug 3 is inserted or removed, the locking member 2 is simply in a compressed state. At this time, the locking member 2 will not affect the insertion or removal of the plug 3, and the plug 3 can freely enter and exit the insertion cavity 121. After the plug 3 is fully inserted, the locking member 2 switches from the compressed state to the initial state. At this time, the locking member 2 is on the movement path of the plug 3, and the locking member 2 can prevent the plug 3 from leaving the insertion cavity 121, thereby locking the plug 3. This enables quick insertion and connection of the plug 3 and the quick socket, and the overall structure is simpler.

[0052] In some examples, when the plug 3 is inserted, the plug 3 moves the locking member 2, causing the locking member 2 to move toward the housing 11 to the pressing position. Alternatively, the locking member 2 can be moved toward the housing 11 to the pressing position by other structures. For example, a movable structure connected to the locking member 2 (e.g., a lever protruding from the housing 11 and movable relative to the housing 11) can be provided, which can move the locking member 2 toward the housing 11 to the pressing position.

[0053] Related quick-connectors, such as CN212430113U, have two rows of ball bearings with different diameters, resulting in a complex structure. This makes them prone to misalignment or incorrect installation during assembly, such as misplacing a small ball bearing in the position of a large ball bearing, or vice versa, severely impacting the performance and quality of the quick-connect product. In contrast, this application only requires a locking element 2, resulting in a simpler structure and eliminating the risk of misalignment or incorrect installation.

[0054] In related technologies, in order to ensure that the locking member 2 can move without disengaging, a relatively complex structure is designed to limit the locking member 2. However, this application uses the limiting part 13 to prevent the locking member 2 from continuing to move into the insertion cavity 121 in the initial state, which can prevent the locking member 2 from disengaging from the guide hole 122, and achieve the limitation of the locking member 2 with a simple structure.

[0055] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The quick-connect socket also includes an elastic locking element 4, which is disposed between the housing 11 and the valve body 12. When the locking element 2 is in the initial position, the elastic locking element 4 applies an elastic force to the locking element 2 to keep the locking element 2 in the initial position. When the locking element 2 is in the squeezed position, the elastic locking element 4 is squeezed by the locking element 2 and undergoes elastic deformation.

[0056] Understandably, in the initial position, the locking member 2 is limited by the limiting part 13 and cannot move into the insertion cavity 121. At the same time, the elastic locking member 4 applies an elastic force to the locking member 2, preventing the locking member 2 from moving away from the insertion cavity 121, thus keeping the locking member 2 in the initial position. When the locking member 2 is in the initial position, it can effectively prevent the plug 3 from leaving the insertion cavity 121, ensuring the locking effect on the plug 3.

[0057] When the plug 3 needs to be removed from the socket 121 or inserted into the socket 121, the locking member 2 moves toward the outer shell 11 to the pressing position. During the movement of the locking member 2, the locking member 2 gradually presses the elastic locking member 4. When the locking member 2 is in the pressing position, the elastic locking member 4 is compressed by the locking member 2 and is in a state of elastic deformation. When the plug 3 is inserted into the designated position or the plug 3 is removed from the socket 121, the elastic locking member 4 will restore its deformation and apply an elastic force to the locking member 2, so that the locking member 2 returns to its initial position, realizing the automatic reset of the locking member 2.

[0058] In some embodiments, see Figure 2 , Figure 3 , Figure 4 and Figure 8 The limiting part 13 includes a limiting block 131 protruding from the inner wall surface of the outer shell 11. Along the axial direction of the valve body 12, the limiting block 131 is located on the side of the locking member 2 away from the elastic locking member 4. When the locking member 2 is in the initial position, the limiting block 131 abuts against the other end of the locking member 2 to prevent the locking member 2 from moving into the insertion cavity 121.

[0059] Understandably, when the locking member 2 is in the initial position, the other end of the locking member 2 abuts against the limiting block 131. Since the limiting block 131 is located on the side of the locking member 2 away from the elastic locking member 4, the limiting block 131 can prevent the locking member 2 from continuing to move away from the elastic locking member 4, that is, it can prevent the locking member 2 from continuing to move into the insertion cavity 121. This can prevent the locking member 2 from moving into the insertion cavity 121 after it is in the initial state, so that the locking member 2 can be stably in the initial state.

[0060] It is understandable that the limiting block 131 is set on the side of the locking member 2 away from the elastic locking member 4, so that the limiting block 131 will not block the locking member 2 from moving toward the elastic locking member 4, that is, toward the direction away from the insertion cavity 121, so that the locking member 2 can switch from the initial state to the compression state.

[0061] In some embodiments, see Figure 3 Along the axial direction of the valve body 12, a groove 21 is formed on the side of the locking member 2 away from the elastic locking member 4. When the locking member 2 is in the initial position, the limiting block 131 is engaged in the groove 21.

[0062] It is understandable that when the locking member 2 is in the initial position, the limiting block 131 is engaged with the slot 21, so that the limiting block 131 can effectively limit the locking member 2 and prevent the locking member 2 from continuing to move into the insertion cavity 121.

[0063] In some embodiments, the housing 11 may be movable relative to the valve body 12 so that the limiting block 131 causes the locking member 2 to move from the initial position to the compression position.

[0064] Understandably, when it is necessary to remove the plug 3 from the insertion cavity 121 or to insert the plug 3 into the insertion cavity 121, the locking member 2 needs to be switched from the initial position to the pressing position. In this embodiment, by setting the outer shell 11 to be movable relative to the valve body 12, the movement of the outer shell 11 can drive the movement of the limiting block 131, which in turn drives the locking member 2 to move from the initial position to the pressing position, which is simple and convenient.

[0065] Understandably, in the initial position, the limiting block 131 serves to limit the locking member 2. When it is necessary to switch the locking member 2 from the initial position to the pressing position, the limiting block 131 also serves to move the locking member 2, so that the limiting block 131 has at least two functions at the same time, which simplifies the structure of the quick-connect socket.

[0066] In some examples, in the initial state, the locking element 2 is at least partially on the movement path of the limiting block 131.

[0067] In some embodiments, see Figure 6 , Figure 7 The locking member 2 includes a connecting block 22 and a main body 23. The connecting block 22 is connected to one end of the main body 23, and the other end of the main body 23 passes through the guide hole 122. The diameter of the connecting block 22 is larger than the diameter of the guide hole 122.

[0068] The limiting part 13 includes a limiting surface 132 formed on the outer surface of the valve body 12. When the locking member 2 is in the initial position, the limiting surface 132 abuts against the connecting block 22 to prevent the locking member 2 from moving into the insertion cavity 121.

[0069] It is understandable that the main body 23 of the locking member 2 can move relative to the guide hole 122. The diameter of the connecting block 22 of the locking member 2 is set to be larger than the diameter of the guide hole 122. When the connecting block 22 moves to the opening of the guide hole 122, the connecting block 22 will be blocked by the limiting surface 132 on the outer surface of the valve body 12 and will not be able to continue to move into the guide hole 122. This will limit the locking member 2 and prevent the locking member 2 from continuing to move into the insertion cavity 121. This will prevent the locking member 2 from moving into the insertion cavity 121 after it is in the initial state, so that the locking member 2 can be stably in the initial state.

[0070] In some embodiments, a protrusion is formed on the inner wall surface of the housing 11. Along the axial direction of the valve body 12, the protrusion is located on the side of the connecting block 22 away from the elastic locking member 4, and the connecting block 22 is located on the moving path of the protrusion.

[0071] The housing 11 is movable relative to the valve body 12 so that the protrusion moves the locking member 2 from its initial position to the compression position.

[0072] Understandably, when it is necessary to remove the plug 3 from the insertion cavity 121 or to insert the plug 3 into the insertion cavity 121, the locking member 2 needs to be switched from the initial position to the pressing position. In this embodiment, by making the outer shell 11 movable relative to the valve body 12, the movement of the outer shell 11 can drive the protrusion to move, thereby driving the locking member 2 to move from the initial position to the pressing position, which is simple and convenient.

[0073] In some examples, in the initial state, the connecting block 22 is at least partially located on the movement path of the bump.

[0074] In some embodiments, the guide hole 122 extends from the inner wall of the valve body 12 to the outer wall of the valve body 12 and obliquely toward the elastic locking member 4.

[0075] It is understandable that the guide hole 122 is set to be inclined toward the elastic locking member 4, so that the guide hole 122 can guide the locking member 2 to the elastic locking member 4.

[0076] In some embodiments, see Figure 1 The elastic locking element 4 includes a locking ring 41 and a third elastic element 42. Both the locking ring 41 and the third elastic element 42 are sleeved on the valve body 12. The locking ring 41 is located between the third elastic element 42 and the locking element 2.

[0077] Understandably, when the locking member 2 is in the initial position, the third elastic member 42 applies an elastic force towards the locking member 2 to the locking ring 41, and the locking ring 41 transmits the elastic force to the locking member 2 to prevent the locking member 2 from moving, thus keeping the locking member 2 in the initial position. When the locking member 2 is in the compressed position, the locking member 2 compresses the locking ring 41, and the locking ring 41 compresses the third elastic member 42, causing the third elastic member 42 to deform.

[0078] In some examples, see Figure 7The locking ring 41 has a guide slope 411 on the side near the locking member 2. The guide slope 411 abuts against the locking member 2. When the locking member 2 switches from the initial position to the pressing position, the locking member 2 will move toward the locking ring 41. At this time, the guide slope 411 can guide the locking member 2, so that the locking member 2 can move along the guide slope 411 and push the locking ring 41 away from the guide hole 122.

[0079] According to a second aspect of this application, this disclosure provides a connector assembly. (See also...) Figure 4 , Figure 5 and Figure 6 The connector assembly includes a plug 3 and the aforementioned quick-connect socket, and the plug 3 is movable relative to the insertion cavity 121.

[0080] It is understood that the connector assembly of this application simplifies the limiting structure of the locking member 2 by movably setting the locking member 2 within the guide hole 122 and limiting the locking member 2 with the limiting part 13, so that the locking member 2 will not fall into the plug cavity 121 when it is in the initial state. When the plug 3 is inserted or removed, the locking member 2 is in the squeezed state. At this time, the locking member 2 will not affect the insertion and removal of the plug 3, and the plug 3 can freely enter and exit the plug cavity 121. After the plug 3 is inserted, the locking member 2 switches from the squeezed state to the initial state. At this time, the locking member 2 is in the movement path of the plug 3. The locking member 2 can prevent the plug 3 from leaving the plug cavity 121, thereby locking the plug 3. This enables the plug 3 and the quick socket to be quickly connected and connected, and the overall structure is simpler.

[0081] In some embodiments, see Figure 2 The plug 3 includes a plug body 31 and a mating part 32 that are connected to each other.

[0082] When the plug 3 moves into the insertion cavity 121, the mating part 32 is adapted to abut against the locking member 2 and drive the locking member 2 to move toward the outer shell 11.

[0083] When the plug 3 is inserted into the insertion cavity 121, the locking member 2 is in the initial position and abuts against the first side wall 321 of the mating part 32 facing out of the insertion cavity 121 to prevent the mating part 32 from moving.

[0084] It is understandable that when the plug 3 is inserted into the insertion cavity 121, the mating part 32 can drive the locking member 2 to move, so that the locking member 2 switches from the initial position to the pressing position. That is, the plug 3 can drive the locking member 2 to the pressing position during the insertion process, which simplifies the structure of the quick-connect assembly.

[0085] When the plug 3 is inserted into the insertion cavity 121, the mating part 32 can abut against the locking member 2, so that the locking member 2 can prevent the plug 3 from moving, thereby locking the plug 3 and simplifying the structure of the quick-connect assembly.

[0086] In some examples, when the plug 3 is not inserted into the insertion cavity 121, the locking member 2 is in the initial position, and the elastic locking member 4 abuts against the locking member 2 and applies an elastic force to the locking member 2, so that the locking member 2 remains in the initial position.

[0087] When plug 3 is inserted into socket 121, since locking member 2 is located on the moving path of plug 3, plug 3 will first contact locking member 2 and push locking member 2 to the pressing position, so that locking member 2 presses elastic locking member 4. At this time, locking member 2 will not block the movement of plug 3, so that plug 3 can continue to move into socket 121. When plug 3 is fully inserted into socket 121, locking member 2 will return to its initial position. At this time, locking member 2 will no longer press elastic locking member 4, and elastic locking member 4 will restore its deformation and apply elastic force to locking member 2 to prevent locking member 2 from moving to the pressing position, so that locking member 2 can lock plug 3 in socket 121, realizing quick connection between plug 3 and sleeve 1.

[0088] In other words, this application movably positions the locking member 2 within the guide hole 122. When the plug 3 is inserted, the plug 3 can push the locking member 2 from its initial position to the pressing position, whereby the locking member 2 presses against the elastic locking member 4. When the plug 3 is inserted into the insertion cavity 121, the plug 3 no longer presses against or pushes the locking member 2. The elastic locking member 4 will recover its deformation and apply an elastic force to the locking member 2, causing the locking member 2 to return to its initial position. That is, the locking member 2 returns to the moving path of the plug 3. At this time, the locking member 2 is held in its initial position by the resistance of the elastic locking member 4, allowing the locking member 2 to lock the plug 3. This achieves quick insertion and connection between the plug 3 and the sleeve 1, and the overall structure is simpler.

[0089] In some embodiments, see Figure 2 The mating part 32 includes a second side wall 322, which faces the interior of the insertion cavity 121 and gradually slopes towards the center of the plug 3 along the length of the plug 3.

[0090] When the plug 3 moves into the insertion cavity 121, the second side wall 322 abuts against the locking member 2.

[0091] Understandably, as the plug 3 moves into the insertion cavity 121, the locking member 2 is located on the movement path of the second side wall 322. That is, as the plug 3 is inserted, the second side wall 322 will abut against the locking member 2. As the plug 3 continues to be inserted, the second side wall 322 will drive the locking member 2 to move towards the elastic locking member 4. At the same time, since the second side wall 322 is inclined, there will also be relative movement between the second side wall 322 and the locking member 2. The second side wall 322 can gradually push the locking member 2 away from the insertion cavity 121, so that the locking member 2 moves to a pressing state, so that the locking member 2 will not prevent the plug 3 from being inserted, allowing the plug 3 to continue to move into the insertion cavity 121.

[0092] In some embodiments, see Figure 2 The mating part 32 also includes a plane 323, which connects the first side wall 321 and the second side wall 322.

[0093] As the plug 3 moves into the insertion cavity 121, the locking member 2 abuts against the second side wall 322 and the plane 323 in sequence.

[0094] It is understandable that when the second side wall 322 abuts against the locking member 2, as the plug 3 moves, the second side wall 322 can drive the locking member 2 to gradually move away from the insertion cavity 121. When the first side wall 321 abuts against the locking member 2, the plug 3 is already inserted into the insertion cavity 121, and the locking member 2 locks the plug 3.

[0095] In this embodiment, a plane 323 connects the first side wall 321 and the second side wall 322. After the second side wall 322 pushes the locking member 2 to the pressing position, the locking member 2 will abut against the plane 323. At this time, the plane 323 can keep the locking member 2 in the pressing state, while the plug 3 can continue to move into the insertion cavity 121. When the plug 3 is inserted into the insertion cavity 121, the locking member 2 disengages from the plane 323 and contacts the first side wall 321, ensuring that the locking member 2 will return to the initial position to prevent the plug 3 from moving after the plug 3 is inserted into the insertion cavity 121.

[0096] In some embodiments, see Figure 2 The plug 3 also includes a first elastic element 33. One end of the first elastic element 33 is connected to the plug body 31. When the plug 3 is inserted into the insertion cavity 121, the sleeve 1 abuts against and squeezes the other end of the first elastic element 33.

[0097] Understandably, when the plug 3 is inserted into the socket 121, the sleeve 1 will compress the first elastic element 33. When the locking element 2 no longer locks the plug 3, the first elastic element 33 will return to its original shape, and at the same time, the elastic force of the first elastic element 33 will drive the plug 3 away from the sleeve 1, thereby achieving automatic disengagement of the plug 3.

[0098] In some examples, the sleeve 1 also includes a pin, which is fixedly installed on the valve body 12. When the plug 3 is inserted into the insertion cavity 121, the pin is on the movement path of the first elastic element 33. The pin will squeeze the first elastic element 33, causing the first elastic element 33 to deform.

[0099] In some embodiments, see Figure 1 The sleeve 1 includes a second elastic element 14. One end of the second elastic element 14 is connected to the valve body 12. When the plug 3 is inserted into the insertion cavity 121, the plug 3 abuts against and squeezes the other end of the second elastic element 14.

[0100] Understandably, when the plug 3 is inserted into the socket 121, the plug 3 will compress the second elastic element 14. When the locking element 2 no longer locks the plug 3, the second elastic element 14 will return to its original shape, and at the same time, the elastic force of the second elastic element 14 will drive the plug 3 away from the sleeve 1, thereby achieving automatic disengagement of the plug 3.

[0101] In some examples, the second elastic element 14 includes a piston and a spring, with the piston disposed within the insertion cavity 121 and the spring located between the bottom wall of the insertion cavity 121 and the piston. When the plug 3 is inserted into the insertion cavity 121, the plug 3 compresses the piston, which in turn compresses the spring.

[0102] According to a third aspect of this application, this disclosure provides a cooling system. The cooling system includes a quick-connect socket as described above or a connector assembly as described above.

[0103] Understandably, refrigeration systems with quick-connect sockets or connectors simplify the limiting structure of the locking member 2 by movably positioning the locking member 2 within the guide hole 122 and limiting it with the limiting part 13. This prevents the locking member 2 from falling into the plug cavity 121 in its initial state. When the plug 3 is inserted or removed, the locking member 2 is simply in a compressed state, which does not affect the insertion or removal of the plug 3, allowing the plug 3 to freely enter and exit the plug cavity 121. After the plug 3 is fully inserted, the locking member 2 switches from the compressed state to the initial state, placing it on the path of the plug 3. The locking member 2 prevents the plug 3 from leaving the plug cavity 121, thus locking the plug 3. This enables quick connection between the plug 3 and the quick-connect socket, and the overall structure is simpler.

[0104] According to a fourth aspect of this application, this disclosure provides a server. The server includes the cooling system described above.

[0105] Understandably, servers with cooling systems simplify the limiting structure of the locking member 2 by movably positioning the locking member 2 within the guide hole 122 and limiting it with the limiting part 13. This prevents the locking member 2 from falling into the plug cavity 121 in its initial state. When the plug 3 is inserted or removed, the locking member 2 is simply in a compressed state, which does not affect the insertion or removal of the plug 3, allowing the plug 3 to freely enter and exit the plug cavity 121. After the plug 3 is fully inserted, the locking member 2 switches from the compressed state to the initial state, placing it on the movement path of the plug 3. The locking member 2 prevents the plug 3 from leaving the plug cavity 121, thus locking the plug 3. This enables quick connection and engagement between the plug 3 and the quick-connect socket, and the overall structure is simpler.
