Description

Technical Field

[0001] This application relates to the technical field of connectors, and in particular to push-button self-closing connectors. Background Technology

[0002] Connectors, specifically pipe connectors, are key components for ensuring the safe and efficient transport of gases and liquids. They come in various types, including compression fittings, threaded connectors, VCR connectors, quick-connect connectors, and flange connectors. However, all of these connectors share a common problem: when workers need to move instruments connected to pipes, they must disconnect the instrument from the pipe connector. If workers forget to close the valve of the instrument and directly disconnect the connector, it will lead to leakage of gas or liquid inside the instrument. In particular, some instruments contain gases or liquids that are harmful to the human body, which may cause workers to inhale harmful gases or come into contact with harmful liquids. Therefore, this application proposes a push-button self-closing connector. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this application is to provide a push-button self-closing connector for preventing gas or liquid leakage from the internal pipelines of automated machinery when the connector is disconnected by an operator.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: a button-type self-closing connector, including a socket and a plug. The socket includes a socket housing, a limiting component disposed inside the socket housing for locking the plug, a socket end cap disposed at one end of the socket housing for connecting to other pipelines, and a sealing component disposed inside the socket housing for sealing the internal space of the socket housing. The socket housing has a through-hole and a mounting cavity. The limiting component is located inside the through-hole, the socket end cap is connected to the mounting cavity, and the sealing component is disposed inside the mounting cavity. The through-hole and mounting cavities are interconnected. The end of the socket housing away from the socket end cap has a plug interface for inserting the plug into the through-hole. The plug includes a plug housing for inserting into the socket housing, a plug end cap disposed at one end of the plug housing for connecting to other pipelines, and a release component disposed inside the other end of the plug housing for releasing the sealing component.

[0005] Furthermore, the socket end cap has a connecting cavity and a flow channel cavity that pass through the socket end cap. The end of the socket end cap with the connecting cavity is located inside the socket housing. The connecting cavity and the flow channel cavity are interconnected. The sealing assembly includes a socket valve body that abuts against the side of the mounting cavity near the separating cavity, a flow channel that is opened on the end face of the socket valve body near the separating cavity and passes through the socket valve body, a socket valve core that is slidably inserted into the end of the flow channel near the socket end cap, and a sealing spring that is disposed inside the connecting cavity to push the socket valve core to fully extend into the flow channel. The periphery of the end of the socket valve core away from the sealing spring has a flow channel opening that passes through the socket valve core. The socket valve core has a socket top rod that extends towards the separating cavity and protrudes from the socket valve core.

[0006] Furthermore, the plug tail cap has a conduit cavity and a fixed cavity that pass through the plug tail cap. The plug housing has a tail cap cavity and a connecting cavity that pass through the plug housing. The tail cap cavity and the connecting cavity are interconnected. The end of the plug tail cap with the fixed cavity is located inside the tail cap cavity. The unsealing assembly includes an unsealing shell disposed inside the fixed cavity and which is hollow inside; a conical shell disposed at the end of the unsealing shell away from the conduit cavity and which connects to the internal space of the unsealing shell; a plug valve core disposed at the end of the conical shell away from the unsealing shell; and a plug top rod disposed at the end of the plug valve core away from the conical shell and which extends toward the connecting cavity. The plug top rod extends into the connecting cavity. A connection port that passes through the conical shell is opened around the periphery of the conical shell. The end of the unsealing shell away from the conical shell connects to the conduit cavity. There is a gap between the plug top rod and the inner wall of the connecting cavity. There is a gap between the plug valve core and the inner wall of the tail cap cavity.

[0007] By adopting the above technical solution, when installing the connector, first install the socket on the instrument storing gas or liquid, so that the flow channel cavity of the socket cap is connected to the instrument. Then, install the plug on the pipeline, so that the pipeline cavity of the plug cap is connected to the pipeline. Next, align the plug with the socket, so that the plug shell is aligned with the separation cavity of the socket shell. Then, push the plug to insert it into the socket, so that the end of the plug shell with the connecting cavity passes through the separation cavity and extends into the flow channel of the socket valve body. At this time, the plug push rod moves backward against the socket push rod, so that the socket valve core flows into the flow channel of the socket cap. As the cavity moves, the sealing spring is compressed. As the socket valve core moves, the flow channel on the socket valve core is gradually exposed. At this time, the limiting component locks the plug housing, so that the plug is locked onto the socket. In this state, the internal spaces of the plug and socket are interconnected. Liquid or gas enters from the flow channel cavity, flows into the flow channel through the flow channel opening, then flows through the connecting cavity of the plug housing into the tail cap cavity, then flows through the connection port of the conical shell into the pipe cavity of the plug tail cap, and finally flows into the pipe along the pipe cavity to complete the gas transportation. When staff need to move the instrument connected to the pipeline, they simply need to press down the limiting component to release the restriction on the plug housing, and then unplug the plug. During this process, the plug rod no longer abuts against the socket rod. After the socket rod loses the thrust of the plug rod, the socket valve core is pushed into the flow channel by the compressed sealing spring, causing the socket valve core to gradually insert into the flow channel, so that the flow channel opening is no longer exposed. At this time, the socket valve core completely seals the mounting cavity of the socket housing, and the gas and liquid inside the instrument are also blocked by the socket valve core, thereby preventing gas and liquid leakage. This allows staff to automatically close the internal pipeline of the instrument without any additional operation, simply by unplugging the plug, to prevent gas or liquid leakage. It achieves the purpose of automatically closing the internal pipeline of the instrument to prevent gas or liquid leakage when the staff disconnects the connector.

[0008] Furthermore, the plug housing has a limiting groove located on the outside of the plug housing at the middle of one end of the connecting cavity, and the socket housing has a vertical mounting slot extending into the separation cavity on the outside. The limiting component includes a limiting post that slides into the mounting slot, a limiting opening that extends through the middle of the limiting post for the plug to pass through, a limiting ring fixedly disposed on the inner wall of the limiting opening for extending into the limiting groove to hold the plug housing, and a limiting spring disposed on the bottom surface of the separation cavity for pushing the limiting post out of the mounting slot. The inner diameter of the limiting ring is larger than the outer diameter of the end of the plug housing with the connecting cavity.

[0009] By adopting the above technical solution, during the plug-socket connection process, the end of the plug housing with the communicating cavity first enters the socket housing. As the operator pushes, the plug housing passes through the limiting port and extends into the socket valve core, making the plug fully connected to the socket. At this time, the limiting groove on the outside of the plug housing is perpendicular to the limiting ring. Simultaneously, the limiting spring pushes the limiting post upward, causing the lower half of the limiting ring to extend into the limiting groove and lock the plug housing. When it is necessary to separate the plug from the socket, simply press the limiting post downward to move the limiting post downward, and the lower half of the limiting ring will disengage from the limiting groove. Because the inner diameter of the limiting ring is larger than the outer diameter of the end of the plug housing with the communicating cavity, it is only necessary to pull the plug away from the socket.

[0010] Furthermore, an inclined surface is provided at the connection between the tail cap cavity and the connecting cavity, and an inclined portion is provided on the periphery of the plug valve core near the end of the connecting cavity for abutting against the inclined surface. The unsealing housing is provided with a support spring that abuts against the inner wall of the fixed cavity and is used to push the unsealing housing to move towards the connecting cavity.

[0011] By adopting the above technical solution, although the setting of the unsealing component can prevent the sealing component from sealing the space inside the socket housing, there may still be gas or liquid inside the pipe when the operator disconnects the connector. Therefore, gas or liquid leakage may also occur inside the plug. The setting of the inclined surface, inclined part and support spring solves this technical problem. Under normal conditions, the inclined surface and inclined part are in a close fit, so that the plug valve core blocks the connection between the connecting cavity and the tail cap cavity. When the plug is inserted into the socket, when the plug rod abuts against the socket rod, the plug rod will also be pushed backward. This push will cause the plug valve core to move backward, so that the inclined part is no longer in contact with the inclined surface, so that the plug valve core no longer blocks the connecting cavity. At the same time, the unsealing housing will push the support spring to compress. At this time, the operator continues to push the plug, so that the support spring is compressed to the limit. At this time, the plug rod no longer has the space to move backward. Then the operator continues to push the plug, so that the plug rod pushes the socket rod backward. In this way, the entire internal space of the connector is in a connected state, which can provide a path for the flow of gas or liquid. When the operator unplugs the connector, the plug rod no longer abuts against the socket rod, allowing the plug rod to move forward. At this time, the support spring pushes the unsealed housing forward, simultaneously moving the plug valve core forward. This causes the inclined part to re-apply to the inclined surface, blocking the connecting cavity with the plug valve core. The internal space of the connector is sealed by the plug valve core, preventing gas or liquid leakage from the pipeline. Furthermore, the inclined surface, inclined part, and support spring design allow the connector to be installed on instruments containing gas or liquid. This ensures that both the connector's plug and socket automatically close the internal pipeline of the instrument, improving the connector's practicality and applicability.

[0012] Furthermore, a plug valve core sealing ring is fixedly provided on the inclined portion of the plug valve core.

[0013] While the above technical solution allows the inclined surface and inclined part to block the connecting cavity of the plug valve core, when the connector is used in a pipeline transporting liquid, the liquid flow through the plug valve core may wear down the inclined surface or inclined part, causing the inclined surface and inclined part to not fit tightly together, resulting in gaps between them. The plug valve core sealing ring solves this technical problem. With the plug valve core sealing ring, when the inclined surface or inclined part is worn down by the liquid, the plug valve core sealing ring, through its own elastic properties, can tightly fit the inclined surface when the support spring pushes the plug valve core forward, thereby filling the gap between the inclined surface and the inclined part and further preventing gas leakage inside the plug.

[0014] Furthermore, both the end of the socket cap with the flow channel cavity and the end of the plug cap with the pipeline cavity are threaded with dust covers.

[0015] By adopting the above technical solution, the socket end cap and plug end cap are sealed to prevent dust from entering the socket end cap and plug end cap during transportation.

[0016] Furthermore, the outer side of the socket housing is provided with anti-slip texture.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a closed assembly, when staff need to move instruments with connected pipes, they only need to press down the limiting assembly to release the restriction on the plug housing, and then unplug the plug. During this process, the plug rod no longer abuts against the socket rod. After the socket rod loses the thrust of the plug rod, the socket valve core is compressed by the closing spring, pushing it to move inside the flow channel, causing the socket valve core to gradually insert into the flow channel, so that the flow channel opening is no longer exposed. At this time, the socket valve core completely seals the mounting cavity of the socket housing, and the gas and liquid inside the instrument are also blocked by the socket valve core, thereby preventing gas and liquid leakage. This allows staff to automatically close the internal pipeline of the instrument without any additional operation, simply by unplugging the plug, to prevent gas or liquid leakage. This achieves the purpose of automatically closing the internal pipeline of the instrument to prevent gas or liquid leakage when the connector is disconnected.

[0018] 2. By incorporating the inclined surface, inclined section, and support spring, when the operator unplugs the plug, the plug rod no longer abuts against the socket rod, allowing the plug rod to move forward. At this time, the support spring pushes the unsealing housing forward, simultaneously moving the plug valve core forward, causing the inclined section to re-apply to the inclined surface. This causes the plug valve core to block the connecting cavity, sealing the internal space of the plug and preventing gas or liquid leakage from the pipeline. Furthermore, the inclined surface, inclined section, and support spring allow the plug to be installed on instruments containing gas or liquid, enabling both the plug and socket of the connector to automatically close the internal pipeline of the instrument, thereby improving the practicality and applicability of the connector.

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] Reference Figure 1 , Figure 2 A push-button self-closing connector includes a socket 1 and a plug 2. The socket 1 includes a socket housing 10, a limiting component 3 disposed inside the socket housing 10 for locking the plug 2, a socket end cap 11 disposed at one end of the socket housing 10 for connecting to other pipes, and a sealing component 4 disposed inside the socket housing 10 for sealing the internal space of the socket housing 10. The socket housing 10 has a separation cavity 12 and a mounting cavity 13 that pass through the socket housing 10. The limiting component 3 is located inside the separation cavity 12, the socket end cap 11 is connected to the mounting cavity 13, and the sealing component 4 is disposed inside the mounting cavity 13. The separation cavity 12 and the mounting cavity 13 are interconnected. The end of the socket housing 10 away from the socket end cap 11 has a plug interface 14 that connects to the separation cavity 12 and is used for inserting the plug 2. The plug 2 includes a plug housing 20 for inserting into the socket housing 10, a plug end cap 21 disposed at one end of the plug housing 20 for connecting to other pipes, and a release component 5 disposed inside the other end of the plug housing 20 for releasing the sealing state of the sealing component 4.

[0023] The socket cap 11 has a connecting cavity 110 and a flow channel cavity 111 inside it. One end of the socket cap 11 with the connecting cavity 110 is located inside the socket housing 10. The connecting cavity 110 and the flow channel cavity 111 are interconnected. (Refer to...) Figure 3The sealing assembly 4 includes a socket valve body 40 abutting against the side of the mounting cavity 13 near the separation cavity 12, a flow channel 41 opened on the end face of the socket valve body 40 near the separation cavity 12 and passing through the socket valve body 40, a socket valve core 42 slidably inserted into the end of the flow channel 41 near the socket cap 11, and a sealing spring 43 disposed inside the connecting cavity 110 for pushing the socket valve core 42 to fully extend into the flow channel 41. A flow channel opening 44 passing through the socket valve core 42 is opened around the end of the socket valve core 42 away from the sealing spring 43. A socket top rod 45 is provided inside the socket valve core 42 extending toward the separation cavity 12 and extending out of the socket valve core 42.

[0024] The plug cap 21 has a conduit cavity 210 and a fixing cavity 211 inside the plug cap 21. The plug housing 20 has a cap cavity 22 and a connecting cavity 23 inside the plug housing 20. The cap cavity 22 and the connecting cavity 23 are interconnected. The end of the plug cap 21 with the fixing cavity 211 is located inside the cap cavity 22. (Refer to...) Figure 4 The unsealing assembly 5 includes an unsealing shell 50 disposed inside the fixed cavity 211 and having a hollow interior; a conical shell 51 disposed on the end of the unsealing shell 50 away from the pipeline cavity 210 and communicating with the interior space of the unsealing shell 50; a plug valve core 52 disposed on the end of the conical shell 51 away from the unsealing shell 50; and a plug rod 53 disposed on the end of the plug valve core 52 away from the conical shell 51 and extending toward the communicating cavity 23. The plug rod 53 extends into the communicating cavity 23. A connection port 54 is provided around the conical shell 51, penetrating the conical shell 51. The end of the unsealing shell 50 away from the conical shell 51 communicates with the pipeline cavity 210. There is a gap between the plug rod 53 and the inner wall of the communicating cavity 23, and a gap between the plug valve core 52 and the inner wall of the tail cap cavity 22.

[0025] The plug housing 20 has a limiting groove 24 located on the outside of the plug housing 20 in the middle of one end of the connecting cavity 23, and the socket housing 10 has a vertical mounting slot 15 extending into the separation cavity 12 on the outside. (Refer to...) Figure 2 The limiting component 3 includes a limiting post 30 that is slidably inserted into the mounting slot 15, a limiting port 31 that is opened through the middle of the limiting post 30 for the plug 2 to pass through, a limiting ring 32 that is fixedly set on the inner wall of the limiting port 31 for extending into the limiting groove 24 to hold the plug housing 20, and a limiting spring 33 that is set on the bottom surface of the separation cavity 12 for pushing the limiting post 30 out of the mounting slot 15. The inner diameter of the limiting ring 32 is larger than the outer diameter of the end of the plug housing 20 that has the communicating cavity 23.

[0026] The socket end cap 11 is connected to the socket housing 10 via a threaded connection. This threaded connection ensures a tight seal within the socket housing 10 and makes assembly of the socket 1 easier and more convenient; simply screw the end cap 11 into the socket housing 10. The plug end cap 21 is also connected to the plug housing 20 via a threaded connection. The sealing spring 43 can be installed inside the socket end cap 11 by placement, bonding, magnetic attraction, or welding. The socket top rod 45 can be installed on the socket valve core 42 by welding, bonding, or magnetic attraction. The conical housing 51 can be installed on the unsealing housing 50 by welding, bonding, magnetic attraction, or as an integral part of the housing. The plug valve core 52 can be installed on the conical housing 51 by welding, bonding, magnetic attraction, or as an integral part of the housing. The plug top rod 53 can be installed on the plug valve core 52 by welding or as an integral part of the housing. The limiting ring 32 can be installed inside the limiting post 30 by welding, bonding, magnetic attraction, or integral molding. The limiting spring 33 can be installed at the bottom of the mounting slot 15 by bonding, magnetic attraction, or placement.

[0027] When installing the connector, first install the socket 1 on the instrument containing gas or liquid, so that the flow channel cavity 111 of the socket cap 11 connects to the instrument. Then, install the plug 2 on the pipeline, so that the pipeline cavity 210 of the plug cap 21 connects to the pipeline. Then, align the plug 2 with the socket 1, so that the plug housing 20 aligns with the separation cavity 12 of the socket housing 10. Then, push the plug 2 to insert it into the socket 1, so that one end of the plug housing 20 with the connecting cavity 23 passes through the separation cavity 12 and the limiting post 30 and extends into the flow channel 41 of the socket valve body 40. At this time, the plug push rod 53 pushes the socket push rod 45 backward, so that the socket valve core 42 moves towards the flow channel cavity 111 of the socket cap 11, and at the same time, the sealing spring 43 is compressed, and the socket valve core 42 moves towards the flow channel cavity 111 of the socket cap 11. As the core 42 moves, the flow channel 44 on the socket valve core 42 is gradually exposed. At this time, the limiting groove 24 on the outside of the plug housing 20 is perpendicular to the limiting ring 32. At the same time, the limiting spring 33 pushes the limiting post 30 upward, so that the lower half of the limiting ring 32 extends into the limiting groove 24, locking the plug housing 20 in this state. The internal spaces of the plug 2 and the socket 1 are interconnected. Liquid or gas enters from the flow channel cavity 111, flows into the flow channel 41 through the flow channel 44, then flows through the connecting cavity 23 of the plug housing 20, flows into the tail cap cavity 22, then flows through the connecting port 54 of the conical housing 51, flows into the pipeline cavity 210 of the plug tail cap 21, and finally flows into the pipeline along the pipeline cavity 210, completing the gas transportation.

[0028] When workers need to move the equipment connecting the pipes, they only need to press down on the limiting post 30 to move it downwards. The lower half of the limiting ring 32 disengages from the limiting groove 24. Because the inner diameter of the limiting ring 32 is larger than the outer diameter of the end of the plug housing 20 with the communicating cavity 23, the plug 2 is in an unrestricted state at this time, and the plug 2 can be pulled out. During this process, the plug rod 53 no longer abuts against the socket rod 45. After the socket rod 45 loses the thrust of the plug rod 53, the socket valve core 42 is pushed into the flow channel 41 by the compressed sealing spring 43. The movement of the connector causes the socket valve core 42 to gradually insert into the flow channel 41, so that the flow channel opening 44 is no longer exposed. At this time, the socket valve core 42 completely seals the mounting cavity 13 of the socket housing 10, and the gas and liquid inside the instrument are also blocked by the socket valve core 42, thereby preventing gas and liquid leakage. This allows the operator to automatically close the internal pipeline of the instrument without any additional operation, simply by unplugging the plug 2, to prevent gas or liquid leakage. This achieves the purpose of automatically closing the internal pipeline of the instrument to prevent gas or liquid leakage when the operator disconnects the connector.

[0029] Although the unsealing component 5 prevents the sealing component 4 from sealing the space inside the socket housing 10, there may still be residual gas or liquid inside the pipe when the connector is disconnected. Therefore, gas or liquid leakage may also occur inside the plug 2. To solve this technical problem, refer to... Figure 4 In this embodiment, an inclined surface 25 is provided at the connection between the tail cap cavity 22 and the connecting cavity 23. An inclined portion 26 is provided around the end of the plug valve core 52 near the connecting cavity 23 for abutting against the inclined surface 25. A support spring 27 is provided inside the unsealing housing 50 for abutting against the inner wall of the fixing cavity 211 and for pushing the unsealing housing 50 to move towards the connecting cavity 23.

[0030] Under normal conditions, the inclined surface 25 and the inclined portion 26 are in contact, causing the plug valve core 52 to block the connection between the connecting cavity 23 and the tail cap cavity 22. When the plug 2 is inserted into the socket 1, and the plug rod 53 abuts against the socket rod 45, the plug rod 53 will also be subjected to a backward thrust. This thrust will cause the plug valve core 52 to move backward, so that the inclined portion 26 is no longer in contact with the inclined surface 25, and the plug valve core 52 no longer blocks the connecting cavity 23. At the same time, the unsealing housing 50 will push the support spring 27 to compress. At this time, the operator continues to push the plug 2, so that the support spring 27 is compressed to its limit. At this time, the plug rod 53 no longer has room to move backward. Then the operator continues to push the plug 2, so that the plug rod 53 pushes the socket rod 45 backward. In this way, the entire internal space of the connector is in a connected state, which can provide a flow path for gas or liquid.

[0031] When the operator unplugs plug 2, plug rod 53 no longer abuts against socket rod 45, allowing plug rod 53 to move forward. At this time, support spring 27 pushes the unsealing housing 50 forward, simultaneously moving plug valve core 52 forward, causing inclined part 26 to once again adhere to inclined surface 25, causing plug valve core 52 to block the connecting cavity 23, thus sealing the internal space of plug 2 and preventing gas or liquid leakage from the pipeline. Furthermore, through the design of inclined surface 25, inclined part 26, and support spring 27, plug 2 can also be installed on instruments storing gas or liquid, enabling both plug 2 and socket 1 of the connector to automatically close the internal pipeline of the instrument, thereby improving the practicality and applicability of the connector.

[0032] Although the engagement of the inclined surface 25 and the inclined portion 26 can block the connecting cavity 23 with the plug valve core 52, when the connector is used in a pipeline for transporting liquids, the liquid flow through the plug valve core 52 may wear down the inclined surface 25 or the inclined portion 26, causing the inclined surface 25 and the inclined portion 26 to not fit tightly, resulting in a gap between the inclined surface 25 and the inclined portion 26. To solve this technical problem, in this embodiment, a plug valve core sealing ring 28 is fixedly provided on the inclined portion 26 of the plug valve core 52. The plug valve core sealing ring 28 can be made of any one of the following rubber materials: nitrile rubber, fluororubber, polyurethane rubber, silicone rubber, or EPDM rubber. All of the above rubber materials have good wear resistance and corrosion resistance.

[0033] With the setting of the plug valve core sealing ring 28, when the inclined surface 25 or the inclined part 26 is worn by liquid, the plug valve core sealing ring 28 can tightly fit the inclined surface 25 when the support spring 27 pushes the plug valve core 52 forward, thereby filling the gap between the inclined surface 25 and the inclined part 26, and further preventing gas leakage inside the plug 2.

[0034] In this embodiment, a dust cover 6 is threadedly installed on one end of the socket end cap 11 with the flow channel cavity 111 and the other end of the plug end cap 21 with the pipeline cavity 210, in order to block the socket end cap 11 and the plug end cap 21 and prevent dust from entering the socket end cap 11 and the plug end cap 21 during transportation.

[0035] In this embodiment, anti-slip texture 16 is provided on the outer side of the socket housing 10 to increase the micro-roughness and contact area of ​​the outer side of the socket housing 10, which can significantly improve the friction of the surface of the socket housing 10, thereby enhancing the anti-slip effect and making it more stable for workers to install the connector.

[0036] Specific implementation process: When assembling socket 1, firstly, slide the socket valve core 42 into the flow channel 41 of the socket valve body 40. Then, install the socket valve body 40 inside the mounting cavity 13 of the socket housing 10, and make the side of the socket valve body 40 away from the socket valve core 42 abut against the side of the mounting cavity 13 near the separation cavity 12. At the same time, it is necessary to ensure that the flow channel 41 is aligned with the connection between the mounting cavity 13 and the separation cavity 12. Then, install the sealing spring 43 in the connecting cavity 110 of the socket tail cap 11, and then install the socket tail cap 11 on the socket housing 10. Then, install the limiting spring 33 in the separation cavity 12 through the mounting slot 15. Then, slide the limiting post 30 into the mounting slot 15. It is important to note that when inserting the limiting post 30, the limiting port 31 should be aligned with the flow channel 41 to complete the assembly of socket 1. When assembling plug 2, first install plug valve core sealing ring 28 on the inclined part 26 of plug valve core 52, then push the entire unsealing component 5 into the plug housing 20 (at this time, it is important to place the unsealing component 5 from the end of plug housing 20 with tail cap cavity 22, and at the same time, make sure that plug push rod 53 is aligned with connecting cavity 23, so as to ensure that plug push rod 53 is accurately inserted into connecting cavity 23). Then install support spring 27 in the fixing cavity 211 of plug tail cap 21, and then install plug tail cap 21 on plug housing 20 to complete the assembly of plug 2.

[0037] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
