Description

Technical Field

[0001] This application relates to the field of connectors, and more particularly to a fluid connector. Background Technology

[0002] A fluid connector is a device used to achieve a detachable connection between two or more fluid systems, enabling reliable transmission of fluid media while maintaining fluid sealing and pressure balance. These connectors are widely used in liquid or gas transmission systems, playing a crucial role, especially in systems where heat conduction and dissipation are achieved using fluid media.

[0003] Existing connector technologies typically employ snap-fit ​​structures, locking mechanisms, or rotary locking mechanisms to ensure a secure connection between the plug and socket. Some connectors utilize elastic snaps or lateral locking blocks to prevent detachment during connection. These structures effectively improve the stability of the connector under vibration, shock, and other environmental conditions.

[0004] However, existing connectors have certain shortcomings in use. Unplugging requires an additional unlocking operation, such as sliding a release tab or rotating an unlocking component, and after unlocking, the plug must be unplugged again. Incomplete unlocking can cause the plug to jam, making it inconvenient to use. The insertion and removal processes are complex, increasing the operational burden in practical applications and severely impacting operational efficiency and user experience. Utility Model Content

[0005] In view of this, it is necessary to provide a connector that is easier to plug and unplug to solve the above problems.

[0006] Embodiments of this application provide a fluid connector, including a plug;

[0007] The socket has an axially oriented insertion cavity, and the socket has a radially penetrating receiving cavity that communicates with the insertion cavity;

[0008] A locking structure includes a reset component and a locking component, wherein the reset component is fixed to the socket and the locking component is elastically connected to the reset component;

[0009] The locking assembly extends into the insertion cavity and is movable within the receiving cavity so that when the plug is inserted into the insertion cavity, the locking assembly locks onto the plug, or when the plug is pulled out, the locking assembly moves to separate from the plug.

[0010] In at least one embodiment of this application, the reset assembly includes a fixing member and an elastic member disposed on the fixing member, the locking assembly has a guide hole, the guide hole is disposed radially along the socket, the fixing member passes through the guide hole, and the elastic member abuts against the locking assembly;

[0011] The plug includes a body and a boss on the outer wall of the body. The boss and the body enclose a groove. When the plug is inserted into the insertion cavity, the boss abuts against the locking assembly. The locking assembly moves radially along the socket and pushes the elastic member. When the locking assembly is facing the groove, the elastic member pushes the locking assembly into the groove to lock the plug.

[0012] In at least one embodiment of this application, the locking assembly includes a locking member and a pressing member, the locking member and the pressing member being spaced apart and circumferentially disposed within the receiving cavity, the inner wall of the receiving cavity being respectively attached to the opposite sides of the locking member and the pressing member, and the locking member partially extending out of the insertion cavity for locking the plug.

[0013] In at least one embodiment of this application, the two ends of the locking member are recessed inward to form engagement grooves, and each of the pressing members is respectively disposed in one of the engagement grooves. When the pressing members on both sides of the locking member are pressed, the pressing members push the locking member to retract into the receiving cavity, thereby unlocking the plug.

[0014] In at least one embodiment of this application, the locking member has a receiving groove, the guide hole communicates with the receiving groove, and the elastic member is disposed in the receiving groove and abuts against the inner wall of the receiving groove.

[0015] In at least one embodiment of this application, the socket includes a housing and a pin and a slider disposed within the housing. The housing has a insertion cavity, the slider is sleeved on the pin and fits against the inner wall of the housing, and the side wall of the pin fits against the inner wall of the slider.

[0016] The socket also includes a first spring at both ends that abuts against the housing and the sliding member respectively. When the plug is inserted into the insertion cavity, the main body pushes the sliding member to slide along the insertion direction. The locking component extends into the groove to lock the plug. When the locking component is unlocked, the first spring pushes the sliding member to reset to push the plug out.

[0017] In at least one embodiment of this application, the main body has an inner cavity, and the plug further includes a valve and a second spring disposed in the inner cavity. One end of the spring is disposed on the main body, and the other end abuts against the valve. The side wall of the valve is attached to the inner wall of the main body.

[0018] When the plug is inserted into the insertion cavity, the pin abuts against the valve and extends into the inner cavity, the locking assembly locks the plug, and the inner cavity communicates with the insertion cavity to form a liquid channel;

[0019] When the locking assembly is unlocked, the first spring pushes the slider to reset, and the second spring pushes the valve to reset to close the liquid passage.

[0020] In at least one embodiment of this application, the socket further includes a sealing element, and the inner wall of the socket is provided with a fixing groove. The sealing element is interference-fitted with the fixing groove and abuts against the outer wall of the sliding element. When the plug is inserted into the insertion cavity, the sealing element abuts against the inner wall of the main body to prevent liquid leakage.

[0021] In at least one embodiment of this application, the boss has a first inclined surface and the locking member has a second inclined surface, the first inclined surface and the second inclined surface are disposed opposite to each other, and when the plug is inserted into the insertion cavity, the boss gradually pushes the locking member to move.

[0022] In at least one embodiment of this application, the socket further includes a stop portion, which extends outward from the interior of the housing to form the stop portion. The stop portion and the locking assembly enclose a limiting groove for abutting the boss to restrict the movement of the plug.

[0023] The fluid connector described above achieves quick locking of the plug and socket by automatically locking the plug when it is inserted into the mating cavity, thus improving the convenience of connection operation. When the plug needs to be removed, the locking component can move within the accommodating cavity to release, allowing the plug to be smoothly removed and avoiding jamming caused by incomplete unlocking. The locking structure provides elastic support through the reset component, ensuring that the locking component always has good reset and locking functions. The overall structure is simple and compact, significantly optimizing the user experience of the connector. Attached Figure Description

[0035] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0036] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0037] Embodiments of this application provide a fluid connector, including a plug;

[0038] The socket has an axially oriented insertion cavity, and the socket has a radially penetrating receiving cavity that communicates with the insertion cavity;

[0039] A locking structure includes a reset component and a locking component, wherein the reset component is fixed to the socket and the locking component is elastically connected to the reset component;

[0040] The locking assembly extends into the insertion cavity and is movable within the receiving cavity so that when the plug is inserted into the insertion cavity, the locking assembly locks onto the plug, or when the plug is pulled out, the locking assembly moves to separate from the plug.

[0041] The fluid connector described above features a locking component that automatically engages the plug when it is inserted into the socket, enabling rapid locking between the plug and socket and improving the convenience of connection operations. When the plug needs to be removed, the locking component (which needs to be pressed) can move within the receiving cavity to release, allowing the plug to be smoothly removed and avoiding jamming caused by incomplete unlocking. The locking structure provides elastic support through a reset component, ensuring that the locking component always has good reset and locking functions. The overall structure is simple and compact, significantly optimizing the user experience of the connector.

[0042] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] Please see Figures 1-9 Embodiments of this application provide a fluid connector 100, including a plug 10;

[0044] The socket 20 has a plug-in cavity 21 opened along the axial direction, and the socket 20 has a receiving cavity 22 that communicates with the plug-in cavity 21 through it in the radial direction;

[0045] The locking structure 30 includes a reset component 31 and a locking component 32. The reset component 31 is fixed to the socket 20, and the locking component 32 is elastically connected to the reset component 31.

[0046] The locking component 32 extends into the insertion cavity 21 and is movable within the receiving cavity 22, so that when the plug 10 is inserted into the insertion cavity 21, the locking component 32 is locked onto the plug 10, or when the plug 10 is pulled out, the locking component 32 moves to separate from the plug 10.

[0047] Specifically, the plug 10 is part of the connector, typically the front end of a fluid connector. It is responsible for the physical connection with the socket 20, ensuring the smooth flow of the fluid medium through the connector after connection, thereby achieving purposes such as cooling. The socket 20 is another part of the fluid connector; its insertion cavity 21 provides space for the plug 10 to be inserted, while the receiving cavity 22 provides space for the locking structure 30, ensuring the proper functioning of the locking assembly 32.

[0048] Furthermore, when the plug 10 is inserted into the insertion cavity 21 of the socket 20, the locking assembly 32 immediately enters and is inserted into the insertion cavity 21. Due to its elastic connection design, the locking assembly 32 moves as the plug 10 is inserted. When the plug 10 is fully inserted, the locking assembly 32 automatically moves into a predetermined position, firmly locking the plug 10 in place, thus forming a stable connection. At this time, the locking assembly 32 ensures that the plug 10 will not loosen due to vibration or external force, and the fluid medium can smoothly pass through the connector for cooling or other operations.

[0049] When the user needs to unplug the plug 10, the locking component 32 moves within the receiving cavity 22 and releases the locking effect on the plug 10. Since the locking component 32 is elastically connected, the movement of the locking component 32 to separate from the plug 10 and release the lock makes the separation of the plug 10 from the socket 20 more convenient and efficient.

[0050] In one specific embodiment, the reset component 31 includes a fixing member 311 and an elastic member 312 disposed on the fixing member 311. The locking component 32 has a guide hole 321, which is arranged radially along the socket 20. The fixing member 311 passes through the guide hole 321, and the elastic member 312 abuts against the locking component 32.

[0051] The plug 10 includes a body 11 and a boss 12 on the outer wall of the body 11. The boss 12 and the body 11 enclose a groove 13. When the plug 10 is inserted into the insertion cavity 21, the boss 12 abuts against the locking component 32. The locking component 32 moves radially along the socket 20 and pushes the elastic member 312. When the locking component 32 is facing the groove 13, the elastic member 312 pushes the locking component 32 into the groove 13 to lock the plug 10.

[0052] Specifically, the fixing member 311 is fixed to the socket 20 and provides support and positioning reference for the elastic member 312 and the locking assembly 32. This ensures accurate guidance and restriction during the movement of the locking assembly 32, guaranteeing consistency and stability of action and preventing the locking member 312 from shaking or malfunctioning. The elastic member 312 stores elastic potential energy, which is used to drive the locking assembly 32 to automatically return to the locked position after the external force is released. This achieves automatic locking after the plug 10 is inserted and rapid reset of the locking assembly 32 after the plug 10 is removed, without additional manual intervention, improving operational convenience and connection reliability.

[0053] Furthermore, the guide hole 321 is radially arranged along the socket 20, and the fixing member 311 passes through it, allowing the locking assembly 32 to slide smoothly only radially under the guidance of the fixing member 311. This avoids misalignment and jamming of the locking assembly 32, improves the smoothness and consistency of connection and unlocking actions, and reduces the failure rate.

[0054] Furthermore, the boss 12 and the main body 11 enclose a groove 13, providing a locking area for the locking assembly 32. During insertion, the boss 12 pushes the locking assembly 32 to move. When the groove 13 aligns with the locking assembly 32, the elastic element 312 pushes the locking assembly 32 into the groove 13. Physical locking is achieved through structural changes (boss 12—groove 13), ensuring that the plug 10 is stable and resistant to being pulled out after being connected to the socket 20.

[0055] Furthermore, the locking assembly 32 is supported by the fixing member 311 through its own guide hole 321. Under the action of the elastic member 312, the locking assembly 32 naturally maintains its position extending into the insertion cavity 21, ready to lock the plug 10 to be inserted. The locking assembly 32 is radially positioned and stable, and will not wobble or shift in the axial or other directions. The boss 12 on the outer wall of the plug 10 first contacts the side wall of the locking assembly 32 extending into the insertion cavity 21; as the plug 10 continues to be inserted, the boss 12 applies a radial thrust to the locking assembly 32. Under the thrust of the boss 12 of the plug 10, the locking assembly 32, guided by the guide hole 321 through which the fixing member 311 passes, can only move radially along the socket 20. The sliding fit between the locking assembly 321 and the fixing member 311 ensures that the movement path is precisely controlled. As the plug 10 continues to be inserted, when the locking assembly 32 moves to a position directly opposite the groove 13 on the outer wall of the plug 10, the locking assembly 32 is in a "spring-in" state, and the elastic element 312 begins to release its stored elastic potential energy. This pushes the locking assembly 32 back in the opposite radial direction. Guided by the cooperation of the fixing element 311 and the guide hole 321, the locking assembly 32 smoothly and accurately extends into the groove 13, achieving mechanical locking.

[0056] In one specific embodiment, the locking assembly 32 includes a locking member 322 and a pressing member 323. The locking member 322 and the pressing member 323 are arranged in annularly staggered within the receiving cavity 22. The inner wall of the receiving cavity 22 is respectively attached to the opposite sides of the locking member 322 and the pressing member 323. The locking member 322 extends out of the insertion cavity 21 to lock the plug 10.

[0057] Specifically, the locking member 322 and the pressing member 323 are key components constituting the locking assembly 32. Their interaction enables the fluid connector to effectively lock and unlock. The locking member 322 directly contacts the plug 10 and provides locking force, while the pressing member 323 adjusts the relative position of the locking member 322 through mechanical force during locking and unlocking, ensuring that the plug 10 is securely locked when connected and easily unlocked when removed. The annular arrangement of the locking member 322 and the pressing member 323 provides a uniform locking force when the plug 10 is inserted. The staggered layout allows the pressing member 323 to smoothly push the locking member 322 during plug insertion and removal. Furthermore, the fit between the inner wall of the receiving cavity 22 and the locking member 322 and the pressing member 323 helps prevent fluid leakage.

[0058] The pressing member 323 and the locking member 322 are collectively confined within the receiving cavity 22. When the locking member 322 slides radially, inwardly recessed engaging grooves 322a are formed at both ends of the locking member 322 to define the position of the pressing member 323. The pressing member 323 is fitted into the engaging grooves 322a, ensuring a secure connection and guaranteeing that the pressing force can be directly and effectively transmitted to the locking member 322 body. When the user presses the pressing member 323, the pressing member 323 pushes the locking member 322 to move radially, thereby achieving the unlocking operation.

[0059] In one specific embodiment, the two ends of the locking member 322 are recessed inward to form engagement grooves 322a, and each of the pressing members 323 is respectively disposed in one of the engagement grooves 322a. When the pressing members 323 on both sides of the locking member 322 are pressed, the pressing members 323 push the locking member 322 back into the receiving cavity 22 to unlock the plug 10.

[0060] Specifically, after the plug 10 is inserted into the socket 20, the locking member 322 in the locking assembly 32 extends into the insertion cavity 21 and engages with the engagement groove 322a of the plug 10, maintaining a secure connection between the plug 10 and the socket 20. In this state, one end of the locking member 322 engages the plug 10, while the other end is held in a fixed position within the receiving cavity 22 by the pressing member 323, thereby ensuring that the plug 10 is securely connected to the socket 20. Pressing on both sides simultaneously pushes both ends of the locking member 322, causing the locking member 322 to retract into the receiving cavity 22 to unlock the plug 10.

[0061] Simultaneous pressing of the pressing members 323 on both sides of the locking member 322 ensures safety and reliability during the unlocking operation. The user must apply force simultaneously to retract the locking member 322 and release the locked state, thereby preventing unlocking caused by unilateral pressing or accidental operation.

[0062] In one specific embodiment, the pressing part 323a is designed in an arc (bent) shape, which allows it to elastically deform when pressed by an external force. The arc shape itself has a certain elastic prestress, which helps to deform smoothly during pressing and release the thrust. The pushing part 323b is integrally formed at both ends of the pressing part 323a, eliminating the need for additional assembly and simplifying the structure. When the pressing part 323a is pressed and deformed, the pushing part 323b is driven to move, thereby pushing the locking member 322 and causing the locking member 322 to slide radially. The integrally formed design enables more stable force transmission and has higher durability and reliability.

[0063] Furthermore, when the user presses the arc-shaped pressing part 323a with their finger, the pressing part 323a deforms inward (radially); this deformation causes the integrated pushing parts 323b on both sides to move together toward the locking member 322; the pushing parts 323b directly push the locking member 322 to slide radially, causing the locking member 322 to exit from the groove 13 of the plug 10, thereby unlocking.

[0064] In one specific embodiment, the locking member 322 has a receiving groove 322b, the guide hole 321 communicates with the receiving groove 322b, and the elastic member 312 is disposed in the receiving groove 322b and abuts against the inner wall of the receiving groove 322b.

[0065] Specifically, a specific-shaped receiving groove 322b is formed on the body of the locking member 322 to accommodate the elastic member 312. The receiving groove 322b provides a defined space for the elastic member 312, ensuring that the position of the elastic member 312 is stable and will not shift or fall off during operation. The elastic member 312 is directly embedded in the locking member 322, resulting in a compact structure. The elastic member 312 works inside the receiving groove 322b and is constrained by the inner wall of the receiving groove 322b, preventing the elastic member 312 from shifting, twisting, or abnormally deforming during operation. Since the elastic member 312 always extends and contracts within a fixed range, it can stably and reliably provide the locking member 322 with a continuous and directional restoring force.

[0066] Furthermore, the fixing member 311 passes through the guide hole 321 and partially extends into the receiving groove 322b. The elastic member 312 is sleeved on the fixing member 311. While supporting the guiding movement of the locking member 322, the fixing member 311 also provides axial positioning for the elastic member 312, ensuring that the compression and reset process of the elastic member 312 always proceeds in the correct direction. Through the sliding guiding function of the guide hole 321, the movement of the locking member 322 is further restricted to radial movement along the socket 20, preventing shaking and jamming. The extension and retraction of the elastic member 312 and the movement of the locking member 322 are both controlled and completed within a designated area inside the receiving groove 322b.

[0067] In one specific embodiment, the socket 20 includes a housing 23 and a pin 24 and a slider 25 disposed within the housing 23. The housing 23 has a insertion cavity 21. The slider 25 is sleeved on the pin 24 and fits against the inner wall of the housing 23, and the side wall of the pin 24 fits against the inner wall of the slider 25.

[0068] The socket 20 also includes a first spring 40 whose two ends respectively abut against the housing 23 and the sliding member 25. When the plug 10 is inserted into the insertion cavity 21, the main body 11 pushes the sliding member 25 to slide along the insertion direction. The locking component 32 extends into the groove 13 to lock the plug 10. When the locking component 32 is unlocked, the first spring 40 pushes the sliding member 25 to reset so as to push the plug 10 out.

[0069] Specifically, the slider 25 can be pushed as the plug 10 is inserted. Its contact with the inner wall of the housing 23 ensures that the slider 25 slides in a restricted direction, and the elastic connection ensures that the slider 25 automatically returns to its initial position after being pushed. When the slider 25 is pushed into place by the plug 10, the locking assembly 32 accurately aligns with the groove 13 formed by the protrusion 12 of the plug 10 and the main body 11, and extends into the groove 13 under the push of the elastic member 312, thus locking the plug 10. When the locking assembly 32 unlocks, the slider 25 moves forward under the action of the elastic restoring force, simultaneously pushing the plug 10 outwards, assisting in the removal action.

[0070] In one specific embodiment, the main body 11 has an inner cavity 111, and the plug 10 further includes a valve and a second spring 15 disposed in the inner cavity 111. One end of the spring is disposed on the main body 11, and the other end abuts against the valve. The side wall of the valve is attached to the inner wall of the main body 11.

[0071] When the plug 10 is inserted into the insertion cavity 21, the pin 24 abuts against the valve and extends into the inner cavity 111, the locking assembly 32 locks the plug 10, and the inner cavity 111 communicates with the insertion cavity 21 to form a liquid channel;

[0072] When the locking assembly 32 is unlocked, the first spring 40 pushes the slider 25 to reset, and the second spring 15 pushes the valve to reset to close the liquid passage.

[0073] Specifically, when the main body 11 of the plug 10 enters the insertion cavity 21, the ejector pin 24 contacts the valve and pushes it into the inner cavity 111 of the plug 10. When the plug 10 enters the insertion cavity 21 and engages with the locking assembly 32, the locking assembly 32 locks the plug 10, ensuring a secure connection. At this time, the liquid passage is also opened, and the opening of the valve allows liquid to flow. This process relies on the first spring 40 pushing the slider 25 to reset and cooperating with the locking action of the locking assembly 32.

[0074] The unlocking process begins with the unlocking of the locking assembly 32. After unlocking, the first spring 40 pushes the slider 25 to reset, causing the plug 10 to be pulled out. At the same time, the second spring 15 activates, pushing the valve to reset and closing the liquid passage to prevent liquid leakage. The valve's reset action, through the elastic force of the second spring 15, closes the liquid passage in the inner cavity 111, preventing accidental liquid leakage after the plug 10 is pulled out.

[0075] Furthermore, the first spring 40 is a dedicated elastic element for pushing the slider 25 to its reset position. It is located inside the housing 23 and works in conjunction with the slider 25. This ensures that the slider 25 can quickly and stably return to its initial position after the plug 10 is removed and the locking member 322 is unlocked. At the end of the slider 25 near the first spring 40, a recessed fixing groove 251 is specifically designed. This groove 251 and the inner wall of the housing 23 define the position of the first spring 40. This ensures accurate positioning of the first spring 40, preventing displacement or misalignment during insertion and removal, making the spring force more stable and uniform, and avoiding obstruction or deviation of the slider 25's movement. This enhances the durability and operational reliability of the entire sliding system.

[0076] In one specific embodiment, the socket 20 further includes a sealing member 28, and a fixing groove 251 is formed on the inner wall of the socket 20. The sealing member 28 is interference-fitted with the fixing groove 251 and abuts against the outer wall of the sliding member 25. When the plug 10 is inserted into the insertion cavity 21, the sealing member 28 abuts against the inner wall of the main body 11. This is used to prevent liquid leakage.

[0077] Specifically, the fixing groove 251 formed on the inner wall of the socket 20 is used to install the seal 28. The function of this groove is to ensure that the seal 28 is securely fixed inside the socket 20, preventing displacement or detachment of the seal 28 during use, which would affect the sealing performance. The fixing groove 251 engages with the seal 28 through an interference fit, allowing the seal 28 to be firmly fixed during insertion and maintaining a stable position. The interference fit between the seal 28 and the fixing groove 251 ensures that the seal 28 is firmly pressed into the groove, preventing loosening or detachment due to vibration or insertion / removal operations, and providing a stronger sealing effect.

[0078] Furthermore, when the plug 10 enters the insertion cavity 21, the ejector pin 24 pushes the valve, and the locking assembly 32 engages the plug 10. Simultaneously, the seal 28 begins to contact the inner wall of the plug 10 body 11, forming a seal to prevent liquid leakage. Upon unlocking, the locking assembly 32 releases, and the first spring 40 and the second spring 15 push the sliding member 25 and the valve to reset, closing the liquid passage. At the same time, the contact between the seal 28 and the plug 10 body 11 is released, preventing liquid leakage.

[0079] In one specific embodiment, the boss 12 has a first inclined surface 121, and the locking member 322 has a second inclined surface 322c. The first inclined surface 121 and the second inclined surface 322c are disposed opposite to each other. When the plug 10 is inserted into the insertion cavity 21, the boss 12 gradually pushes the locking member 322 to move.

[0080] Specifically, the first inclined surface 121 is part of the surface of the boss 12 and is designed with an inclined slope. The second inclined surface 322c is part of the locking member 322 and typically mates with the first inclined surface 121 of the plug 10, having an inclination opposite to that of the first inclined surface 121, forming an interactive design. The inclined surfaces on the boss 12 allow the plug 10 to gradually contact the locking member 32 when inserted into the socket 20. This provides a smooth transition, preventing direct impact or jamming, and ensuring that the plug 10 can be inserted smoothly.

[0081] In one specific embodiment, the socket 20 further includes a stop portion 26, which extends outward from the interior of the housing 23 to form the stop portion 26. The stop portion 26 and the locking assembly 32 enclose a limiting groove 261 for abutting against the boss 12 to restrict the movement of the plug 10.

[0082] Specifically, the stop 26 is a structure extending from the interior of the housing 23 of the socket 20. Its function is to provide a physical limit for the plug 10, preventing over-insertion or reverse movement of the plug 10 during insertion. The main function of the stop 26 is to limit the insertion depth of the plug 10, ensuring that the plug 10 is locked in the correct position and avoiding connection problems caused by excessive insertion or instability of the plug 10.

[0083] Furthermore, the limiting groove 261 is a groove-shaped area enclosed by the stop portion 26 and the locking component 32. Its main function is to provide a precise positioning space for the plug 10, ensuring that the position of the plug 10 in the socket 20 will not move accidentally. The design of the limiting groove 261 helps to improve the connection stability between the plug 10 and the socket 20, ensuring that the locking component 32 can be accurately embedded in the groove 13 of the plug 10 to form a firm connection. The function of the limiting groove 261 is not only to limit the over-insertion of the plug 10, but also to ensure that the locking component 32 can smoothly enter and cooperate with the groove 13 of the plug 10 to achieve stable locking.

[0084] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
