Description

Technical Field

[0001] This invention relates to the field of cable connector technology, and more specifically to a push-pull self-locking cable connector with a safety feature. Background Technology

[0002] Cable connectors are indispensable components in electronic devices. In modern industry, communications, medical equipment, and consumer electronics, connectors are widely used to achieve reliable electrical or signal connections, especially in applications requiring frequent plugging and unplugging or operating in vibrating environments. Currently, the most common connectors on the market mainly include the following two types: The first type is the threaded connector, which, after insertion, rotates a certain angle to align and lock the male head with the latch on the female head. Unlocking is achieved by rotating in the opposite direction. Although it provides a good locking effect, the operation is relatively complex and not suitable for applications requiring frequent plugging and unplugging. In addition, its operation requires the use of tools, which has certain limitations. The second type is the quick-connect connector, which uses spring-loaded pins or clamps to achieve quick connection and disconnection without the need for tools. However, its locking mechanism is relatively simple, and its tensile strength is limited, making it easy to accidentally unlock when subjected to external pulling force.

[0003] For example, a Chinese patent discloses a connector with a push-pull self-locking function (publication number: CN119695594B). This patented technology achieves the effect of plugging and locking the connector by squeezing the corresponding locking buckle. At the same time, since the locking buckles at both ends are rigidly fastened, they will not be unlocked due to displacement caused by pulling or squeezing. However, in actual work, the connector connection is achieved solely by the locking buckle, resulting in poor sealing effect and large connection play. When subjected to external force, the external force can easily affect the pins and sockets. Prolonged shaking can lead to a decrease in connector performance, or even failure and arcing. Furthermore, under extreme conditions, there is still a risk of accidental separation, posing a significant safety hazard. Summary of the Invention

[0004] The technical problem to be solved by this invention is that existing cable connectors have certain limitations, are inconvenient to use, have poor sealing effect, low connection strength, and when subjected to external forces, the connector pins and sockets will also be affected. Prolonged shaking can lead to a decrease in connector performance, or even failure and arcing, which poses a significant safety hazard.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a push-pull self-locking cable connector with safety features, comprising a cable plug and a cable socket that cooperate with each other. The cable plug includes a plug body, a first sealing component, and a push-pull latching component. The cable socket includes a socket body, a second sealing component, and a self-locking component. The first sealing component is arranged around the connection between the plug body and the socket body. The plug body is connected to the socket body via the push-pull latching component. When the cable plug is installed in place, the locking part of the push-pull latching component drives the first sealing component to press against the connection between the plug body and the socket body. The second sealing component is arranged around the connection between the push-pull latching component and the socket body, and abuts against the locking part of the push-pull latching component when the cable plug is installed in place. The second sealing component is connected to the cable plug via the self-locking component, and when the cable plug moves in a direction toward separation, it drives the locking part of the push-pull latching component to press against the socket body. The locking part of the self-locking component is connected to the unlocking part of the push-pull latching component when the cable plug is installed in place.

[0006] When this invention is in operation, it enables direct push-pull installation or disassembly of cable connectors, which is simple to operate and highly reliable. The first sealing component provides pressure sealing to the connection between the plug body and the socket body, and the second sealing component provides secondary sealing, which greatly improves the sealing level of the cable connector and provides good vibration resistance. The locking force of the push-pull buckle component drives the first sealing component to seal the cable connector, achieving sealing upon installation and a high level of protection. At the same time, a self-locking component locks the unlocking part after installation to prevent unintended operation. When attempting to separate the cable connector, the second sealing component, through the reverse driving force of the self-locking component, further drives the locking part to press against the socket body, preventing the cable connector from shaking or loosening due to vibration or accidental pulling.

[0007] Preferably, the push-pull latch assembly includes a latching ring, a push-pull portion, and a reset component. The latching ring is fixedly mounted on the plug body and located around the first sealing component. The push-pull portion is slidably fitted onto the plug body and located around the latching ring. The reset component is installed between the push-pull portion and the plug body and drives the push-pull portion to move along the axial direction of the plug body towards the end where the plug body connects to the socket body. The latching ring has a latching portion at one end near the socket body. When the cable plug is installed in place, the latching portion is driven to engage with the push-pull portion and, driven by the push-pull portion, presses inward against the socket body. The other end of the latching ring has an unlocking portion. When the cable plug is removed, the unlocking portion is driven to engage with the push-pull portion and, driven by the push-pull portion, retracts inward to open the latching portion outward to separate it.

[0008] When the invention is in operation, the axial movement of the push-pull part enables the cable connector to be installed and locked when it acts on the latching part, and enables the cable connector to be quickly removed when it acts on the unlocking part. This allows for intuitive operation of pushing in self-locking and pulling out unlocking, eliminating the need for special installation tools and simplifying the usage steps. At the same time, the reset component continuously pushes the push-pull part towards the socket body, so that the latching part is continuously subjected to force and pressed against the socket body to prevent accidental loosening.

[0009] Preferably, one end of the buckle ring has a plurality of buckle protrusions, and the other end of the buckle ring has an unlocking protrusion that corresponds one-to-one with the plurality of buckle protrusions. Each buckle protrusion and its corresponding unlocking protrusion are arranged in a V-shape. Each buckle protrusion and its corresponding unlocking protrusion are provided with a connecting rib. A gap is maintained between adjacent buckle protrusions to allow one end of the buckle ring to retract inward, and a gap is maintained between adjacent unlocking protrusions to allow the other end of the buckle ring to retract inward.

[0010] When this invention is in operation, the contraction and expansion of both ends of the buckle ring are achieved through the V-shaped arrangement of the buckle protrusions and the unlocking protrusions. The structure is simple, and the operation does not interfere with each other. The connecting ribs improve the efficiency of driving force transmission and the structural strength of the buckle ring, avoiding stress concentration that could lead to breakage. The several circumferentially arranged buckle protrusions can provide uniform locking force. The failure of a single buckle protrusion will not affect the others. The connection effect is good, and the pull-out resistance is good.

[0011] Preferably, one end of the plug body has a first mounting position for inserting a locking ring. The middle of the locking ring has a first limiting protrusion protruding inward. The side of the first mounting position has a first limiting groove for inserting the first limiting protrusion. The first limiting protrusion is slidably mounted in the first limiting groove. When the cable plug is installed, the end of the unlocking protrusion abuts against the outer end of the end face of the first mounting position, and when the cable plug is removed, it abuts against the inner end of the end face of the first mounting position. When the cable plug is removed, the locking ring moves towards the socket body.

[0012] Preferably, one end of the plug body has a second mounting position for the push-pull part to be inserted, the middle of the push-pull part has a second limiting protrusion protruding inward, the side of the second mounting position has a second limiting groove for the second limiting protrusion to be inserted, the second limiting protrusion is slidably limited and mounted in the second limiting groove, and the reset component is arranged in the second limiting groove and located between the second limiting protrusion and the second limiting groove on the end face away from the socket body.

[0013] Preferably, the push-pull part has an inwardly protruding abutting part at one end near the socket body, and the inner diameter of the abutting part is set to be smaller than the outer diameter of the buckle part and the outer diameter of the unlocking part. The other end of the push-pull part has an inwardly protruding sealing part, and the inner diameter of the sealing part is set to be consistent with the side diameter of the second mounting position.

[0014] Preferably, one end of the plug body has a third mounting position for inserting a first sealing component. The first sealing component is annular in shape, with one end fixedly mounted on the side of the third mounting position. The other end of the first sealing component extends outward and then bends towards the socket body, maintaining a gap between the inner wall of the other end of the first sealing component and the outer surface of one end of the plug body for insertion into the socket body. The other end of the first sealing component abuts against the socket body when the cable plug is installed. When the cable plug is installed, the other end of the first sealing component is connected to the locking part of the push-pull latch assembly and, driven by the push-pull latch assembly, abuts against the socket body.

[0015] Preferably, the inner wall surface of the other end of the first sealing component is provided with a plurality of anti-slip sealing ribs, which extend along the axial direction of the first sealing component. The anti-slip sealing ribs are provided with a guide slope that is inclined inward along the axial direction of the plug body away from the socket body at the end of the anti-slip sealing ribs near the socket body.

[0016] When this invention is in operation, the first sealing component tightly wraps around the connection between the plug body and the socket body, thereby completely isolating the connection between the plug body and the socket body after the cable plug is installed. At the same time, the locking part of the push-pull buckle component directly drives the sealing ring to tighten, which can further improve the sealing effect. The anti-slip sealing ribs form multiple sealing lips, which increases the sealing redundancy. The anti-slip sealing ribs rub against the surface of the socket body, which enhances the pull-out resistance and facilitates the smooth passage of the socket when it is inserted, reducing installation resistance and making it convenient to use.

[0017] Preferably, the outer surface of the part where the socket body connects to the plug body is provided with a connecting flange for snap-fit ​​connection with the push-pull buckle assembly. A gap is provided between the end face of the connecting flange away from the plug body and the socket body for the second sealing assembly to be inserted. One end of the second sealing assembly is fixedly installed in the gap, and the other end of the second sealing assembly extends outward and then bends to extend closer to the plug body. The other end of the second sealing assembly maintains a gap with the connecting flange to allow the locking part of the push-pull buckle assembly to be inserted, and is driven to connect with the locking part of the push-pull buckle assembly when the cable plug is installed in place.

[0018] Preferably, the self-locking component is arranged around the second sealing component. One end of the self-locking component is limited and installed on the socket body. The other end of the self-locking component is detachably connected to the unlocking part of the push-pull buckle component when the cable plug is installed in place. The inner end of the self-locking component is drivenly connected to the other end of the second sealing component, and when the cable plug moves in the direction of separation, it drives the other end of the second sealing component to press against the locking part of the push-pull buckle component.

[0019] When this invention is in operation, by arranging the second sealing component at the locking part of the push-pull buckle component, the sealing effect can be further improved, preventing foreign objects from seeping in through the buckle gap. In conjunction with the self-locking component, after the unlocking part of the push-pull buckle component is limited, when the cable plug is forcibly separated, the locking part of the push-pull buckle component can be driven to more tightly engage with the connecting flange, realizing the self-locking function. When unlocking, only the self-locking component needs to be released to separate the cable plug and cable socket, taking into account both safety and maintenance convenience.

[0020] The beneficial technical effects of this invention include: 1. This invention enables direct push-pull installation or disassembly of cable connectors, is easy to operate, and has high reliability. It achieves pressure sealing of the connection between the plug body and the socket body through a first sealing component, and a secondary sealing through a second sealing component, greatly improving the sealing level of the cable connector and providing good vibration resistance. The locking force of the push-pull snap-fit ​​component drives the first sealing component to seal the cable connector, achieving sealing upon installation and a high level of protection. Simultaneously, a self-locking component locks the unlocking part after installation to prevent unintended operation. When attempting to separate the cable connector, the second sealing component, through the reverse driving force of the self-locking component, further drives the locking part to press against the socket body, preventing the cable connector from shaking or loosening due to vibration or accidental pulling.

[0021] 2. This invention achieves cable connector installation and locking when the push-pull part acts on the latching part and quick removal when it acts on the unlocking part by axial movement of the push-pull part. It enables intuitive operation of pushing in self-locking and pulling out unlocking, eliminating the need for special installation tools and simplifying the usage steps. At the same time, the reset component continuously pushes the push-pull part towards the socket body, so that the latching part is continuously pressed against the socket body to prevent accidental loosening.

[0022] 3. This invention achieves the contraction and expansion of both ends of the buckle ring through V-shaped buckle protrusions and unlocking protrusions. The structure is simple and the operation does not interfere with each other. The connecting ribs improve the efficiency of driving force transmission and the structural strength of the buckle ring, avoiding stress concentration that could lead to breakage. The several circumferentially arranged buckle protrusions can provide uniform locking force. The failure of a single buckle protrusion will not affect the others. The connection effect is good and the pull-out resistance is good.

[0023] 4. This invention tightly wraps the first sealing component around the connection between the plug body and the socket body, thereby completely isolating the connection between the plug body and the socket body after the cable plug is installed. At the same time, the locking part of the push-pull buckle component directly drives the sealing ring to tighten, which can further improve the sealing effect. The anti-slip sealing ribs form multiple sealing lips to increase the sealing redundancy. The anti-slip sealing ribs rub against the surface of the socket body to enhance the pull-out resistance and facilitate the smooth passage of the socket when it is inserted, reducing installation resistance and making it convenient to use.

[0024] 5. By arranging the second sealing component at the locking part of the push-pull buckle assembly, the present invention can further improve the sealing effect, prevent foreign objects from seeping in through the buckle gap, and cooperate with the self-locking component. After the limit of the unlocking part of the push-pull buckle assembly is completed, when the cable plug is forcibly separated, it can drive the locking part of the push-pull buckle assembly to more tightly engage with the connecting flange, realizing the self-locking function. When unlocking, only the self-locking component needs to be released to separate the cable plug and cable socket, taking into account both safety and maintenance convenience.

[0027] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0028] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” are used only to indicate orientation or positional relationship for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0029] Please see Figures 1 to 8 This embodiment discloses a push-pull self-locking cable connector with a safety feature, including a cable plug 1 and a cable socket 2 that cooperate with each other. The following is a detailed description with reference to the accompanying drawings.

[0030] In this embodiment, the cable plug 1 includes a plug body 11, a first sealing component 12, and a push-pull latching component 13. The cable socket 2 includes a socket body 21, a second sealing component 22, and a self-locking component 23. The first sealing component 12 is arranged around the connection between the plug body 11 and the socket body 21. The plug body 11 is connected to the socket body 21 via the push-pull latching component 13. When the cable plug 1 is installed in place, the locking part of the push-pull latching component 13 drives the first sealing component 12 to press against the connection between the plug body 11 and the socket body 21. The second sealing component 22 is arranged around the connection between the push-pull latching component 13 and the socket body 21, and locks against the push-pull latching component 23 when the cable plug 1 is installed in place. The locking part of component 13 abuts against each other. The second sealing component 22 is connected to the cable plug 1 via the self-locking component 23. When the cable plug 1 moves in the direction of separation, the locking part of the push-pull latch component 13 is driven to press against the socket body 21. When the cable plug 1 is installed in place, the locking part of the self-locking component 23 is connected to the unlocking part of the push-pull latch component 13. When the cable plug 1 attempts to separate, the second sealing component 22 drives the locking part of the push-pull latch component 13 to press against the socket body 21 further via the self-locking component 23, forming a self-locking effect that tightens as it is pulled, preventing loosening due to vibration or accidental pulling. The sealing, locking, and safety functions are integrated into the push-pull action, making it easy to operate and highly reliable.

[0031] In this embodiment, the cable connector can be installed or removed by direct push-pull, which is simple to operate and highly reliable. The first sealing component 12 provides a pressure seal at the connection between the plug body 11 and the socket body 21, and the second sealing component 22 provides a secondary seal, which greatly improves the sealing level of the cable connector and provides good vibration resistance. The locking force of the push-pull buckle component 13 drives the first sealing component 12 to seal the cable connector, achieving sealing upon installation and a high level of protection. At the same time, the self-locking component 23 locks the unlocking part after installation to prevent unintended operation. When attempting to separate the cable connector, the second sealing component 22, through the reverse driving force of the self-locking component 23, further drives the locking part to press against the socket body 21, preventing the cable connector from shaking or loosening due to vibration or accidental pulling.

[0032] Please see Figure 2 and Figure 3 In specific implementation, the push-pull latch assembly 13 includes a latching ring 131, a push-pull portion 132, and a reset assembly 133. The latching ring 131 is fixedly mounted on the plug body 11 and located around the first sealing assembly 12. The push-pull portion 132 is slidably sleeved on the plug body 11 and located around the latching ring 131. The reset assembly 133 is installed between the push-pull portion 132 and the plug body 11, and drives the push-pull portion 132 to move along the axial direction of the plug body 11 towards the connection between the plug body 11 and the socket body 21. One end of the buckle ring 131 is provided with a buckle part 1311 at the end near the socket body 21. When the cable plug 1 is installed in place, the buckle part 1311 is connected to the push-pull part 132 and pressed against the socket body 21 inward under the drive of the push-pull part 132. The other end of the buckle ring 131 is provided with an unlocking part 1312. When the cable plug 1 is removed, the unlocking part 1312 is connected to the push-pull part 132 and retracts inward under the drive of the push-pull part 132, causing the buckle part 1311 to open outward to separate the buckle part 1311.

[0033] In this embodiment, the axial movement of the push-pull part 132 enables the cable connector to be installed and locked when it acts on the latching part 1311, and enables the cable connector to be quickly removed when it acts on the unlocking part 1312. This allows for intuitive operation of pushing in self-locking and pulling out unlocking, eliminating the need for special installation tools and simplifying the usage steps. At the same time, the reset component 133 continuously pushes the push-pull part 132 towards the socket body 21, so that the latching part 1311 is continuously pressed against the socket body 21 to prevent accidental loosening.

[0034] As a further improvement of this embodiment, one end of the buckle ring 131 is provided with a plurality of buckle protrusions 13111, and the other end of the buckle ring 131 is provided with an unlocking protrusion 13121 corresponding to the plurality of buckle protrusions 13111. Each buckle protrusion 13111 and its corresponding unlocking protrusion 13121 are arranged in a V-shape. Each buckle protrusion 13111 and its corresponding unlocking protrusion 13121 are provided with a connecting rib 1313. A gap is maintained between adjacent buckle protrusions 13111 to allow one end of the buckle ring 131 to retract inward, and a gap is maintained between adjacent unlocking protrusions 13121 to allow the other end of the buckle ring 131 to retract inward.

[0035] In this embodiment, the V-shaped buckle protrusions 13111 and unlocking protrusions 13121 enable the contraction and expansion of both ends of the buckle ring 131. The structure is simple, and the operation does not interfere with each other. The connecting ribs 1313 improve the efficiency of driving force transmission and enhance the structural strength of the buckle ring 131, preventing stress concentration that could lead to breakage. The several circumferentially arranged buckle protrusions 13111 provide uniform locking force. The failure of a single buckle protrusion 13111 will not affect the other buckle protrusions 13111, resulting in good connection and good pull-out resistance.

[0036] Preferably, one end of the plug body 11 has a first mounting position for inserting the retaining ring 131. The retaining ring 131 has a first limiting protrusion 1314 protruding inward from its center. The side of the first mounting position has a first limiting groove 121 for inserting the first limiting protrusion 1314. In this embodiment, to further improve the driving force of the retaining ring 131 on the first sealing assembly 12, the first limiting groove 121 can be arranged on the outer surface of the first sealing assembly 12. In this case, the first sealing assembly 12 can be made of a rigid material encased in a flexible sealing material, possessing both high structural strength and sealing effect. The first limiting protrusion 1314 can... The sliding limiter is installed within the first limiting groove 121. The end of the unlocking protrusion 13121 abuts against the outer end of the first mounting face when the cable plug 1 is installed, and against the inner end of the first mounting face when the cable plug 1 is removed. The latching ring 131 moves towards the socket body 21 when the cable plug 1 is removed. During operation, the push-pull part 132 drives the unlocking part 1312 to retract inwards, causing the latching part 1311 to expand and move towards the socket body 21. This efficiently separates the latching part 1311, preventing difficulties in disassembly due to cable connector deformation after prolonged connection. In this embodiment, one end of the plug body 11 has a second mounting position for the push-pull portion 132 to be inserted. The middle of the push-pull portion 132 has a second limiting protrusion 1321 protruding inward. The side of the second mounting position has a second limiting groove 111 for the second limiting protrusion 1321 to be inserted. The second limiting protrusion 1321 is slidably limited and mounted in the second limiting groove 111. The reset component 133 is arranged in the second limiting groove 111 and is located away from the second limiting protrusion 1321 and the second limiting groove 111. Preferably, between one end face of the base body 21, the push-pull part 132 near the end of the socket body 21 has an inwardly protruding abutment part 1322. The inner diameter of the abutment part 1322 is set to be smaller than the outer diameter of the latching part 1311 and the outer diameter of the unlocking part 1312. When working, the inner diameter of the abutment part 1322 is small, and it will only contact the latching part 1311 or the unlocking part 1312 when it moves axially to a specific position, so as to realize the sequential control of locking and installation. Unlocking will not be accidentally triggered when the abutment part 1322 is not in place. The other end of the push-pull part 132 has a sealing part 1323 protruding inward. The inner diameter of the sealing part 1323 is set to be consistent with the side diameter of the second mounting position, so that the other end of the push-pull part 132 extends backward until it completely encloses the reset assembly 133. At this time, the reset assembly 133 is hidden in the second limiting groove 111, which does not increase the outer diameter of the cable plug 1. The structure is compact and can avoid external contamination, improve the smoothness of the push-pull operation, and make the second limiting protrusion 1321 and the second limiting groove 111 precisely cooperate to control the sliding distance of the push-pull part 132 and ensure accurate locking and unlocking strokes.

[0037] In this embodiment, one end of the plug body 11 is provided with a third mounting position for the first sealing component 12 to be installed. The first sealing component 12 is shaped like a ring. One end of the first sealing component 12 is fixedly installed on the side of the third mounting position. The other end of the first sealing component 12 extends outward and then bends to extend closer to the socket body 21. The inner wall surface of the other end of the first sealing component 12 maintains a gap with the outer surface of one end of the plug body 11 so that the socket body 21 can be inserted. The other end of the first sealing component 12 abuts against the socket body 21 when the cable plug 1 is installed in place. The other end of the first sealing component 12 is connected to the locking part of the push-pull buckle component 13 when the cable plug 1 is installed in place, and is pressed against the socket body 21 under the drive of the push-pull buckle component 13. Preferably, in order to further improve the sealing effect and the smoothness of the push-pull operation, the inner wall surface of the other end of the first sealing component 12 is provided with several anti-slip sealing ribs 122. The several anti-slip sealing ribs 122 extend along the axial direction of the first sealing component 12. The end of the anti-slip sealing rib 122 near the socket body 21 is provided with a guide slope that is inclined away from the socket body 21 along the axial direction of the plug body 11. Of course, a corresponding guide slope can also be provided at the other end of the anti-slip sealing rib 122, which can deform during the push-pull process to reduce friction and improve the operating feel.

[0038] In this embodiment, the first sealing component 12 tightly wraps around the connection between the plug body 11 and the socket body 21, thereby completely isolating the connection between the plug body 11 and the socket body 21 after the cable plug 1 is installed. At the same time, the locking part of the push-pull buckle component 13 directly drives the sealing ring to press against, which can further improve the sealing effect. The anti-slip sealing rib 122 forms multiple sealing lips, which improves the sealing redundancy. The anti-slip sealing rib 122 forms friction with the surface of the socket body 21, which enhances the pull-out resistance and facilitates the smooth passage of the socket when it is inserted, reducing installation resistance and making it convenient to use.

[0039] In specific implementation, the outer surface of the part where the socket body 21 connects with the plug body 11 is provided with a connecting flange 211 for snap-fit ​​connection with the push-pull buckle assembly 13. A gap is provided between the end face of the connecting flange 211 away from the plug body 11 and the socket body 21 for the second sealing assembly 22 to be inserted. One end of the second sealing assembly 22 is fixedly installed in the gap, and the other end of the second sealing assembly 22 extends outward and then bends to extend closer to the plug body 11. The other end of the second sealing assembly 22 maintains a gap with the connecting flange 211 so that the locking part of the push-pull buckle assembly 13 can be inserted, and it is connected to the locking part of the push-pull buckle assembly 13 when the cable plug 1 is installed in place.

[0040] Preferably, the self-locking component 23 is arranged around the second sealing component 22. One end of the self-locking component 23 is limited and installed on the socket body 21. The other end of the self-locking component 23 is detachably connected to the unlocking part of the push-pull buckle component 13 when the cable plug 1 is installed in place. The inner end of the self-locking component 23 is connected to the other end of the second sealing component 22. When the cable plug 1 moves in the direction of separation, it drives the other end of the second sealing component 22 to press against the locking part of the push-pull buckle component 13. During operation, the self-locking component 23 and the push-pull buckle component 13 can be connected by a snap-fit ​​connection or a threaded connection. When using a threaded connection, since the self-locking component 23 only bears force when the snap-fit ​​part 1311 is subjected to a large pulling force, it can complete the self-locking work without a large connection force. When disassembling, the operator can manually rotate the self-locking component 23 to unlock it, which is convenient and quick to operate.

[0041] In this embodiment, by arranging the second sealing component 22 at the locking part of the push-pull buckle component 13, the sealing effect can be further improved, preventing foreign objects from seeping in through the buckle gap. It also works in conjunction with the self-locking component 23. After limiting the unlocking part of the push-pull buckle component 13, when the cable plug 1 is forcibly separated, it can drive the locking part of the push-pull buckle component 13 to more tightly engage with the connecting flange 211, realizing the self-locking function. When unlocking, only the self-locking component 23 needs to be released to separate the cable plug 1 and the cable socket 2, taking into account both safety and maintenance convenience.

[0042] In this embodiment, by arranging the second sealing component at the locking part of the push-pull buckle component, the sealing effect can be further improved, preventing foreign objects from seeping in through the buckle gap. In conjunction with the self-locking component, after the limit of the unlocking part of the push-pull buckle component is completed, when the cable plug is forcibly separated, it can drive the locking part of the push-pull buckle component to more tightly engage with the connecting flange, realizing the self-locking function. When unlocking, only the self-locking component needs to be released to separate the cable plug and cable socket, taking into account both safety and maintenance convenience.

[0043] The beneficial technical effects of this embodiment include: the present invention enables direct push-pull installation or disassembly of cable connectors, which is simple to operate and highly reliable; the first sealing component achieves pressure sealing of the connection between the plug body and the socket body, and the second sealing component provides secondary sealing, which greatly improves the sealing level of the cable connector and provides good vibration resistance; the locking force of the push-pull buckle component drives the first sealing component to seal the cable connector, achieving sealing upon installation and a high level of protection; at the same time, the self-locking component locks the unlocking part after installation to prevent unintended operation; and when attempting to separate the cable connector, the second sealing component further drives the locking part to press against the socket body through the reverse driving force of the self-locking component, preventing the cable connector from shaking or loosening due to vibration or accidental pulling.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
