Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a high-sealing automotive Ethernet connector. Background Technology

[0002] High-sealing automotive Ethernet connectors are designed specifically for automobiles, ensuring stable connections and smooth signal transmission even in harsh environments. They enable reliable Ethernet signal transmission between various electronic devices within the vehicle, such as supporting autonomous driving and in-vehicle entertainment systems, and ensuring the stability and safety of the vehicle's electrical system.

[0003] Although automotive connectors are rarely plugged and unplugged, if dust caps are not promptly replaced during maintenance, the disconnected interfaces will be exposed for extended periods, losing their dust protection. Dust will continuously accumulate in critical areas such as terminals and sealing grooves, and subsequent reconnection will not completely remove it. Dust entering the interface can damage the seal, leading to moisture intrusion, terminal oxidation, increased contact resistance, unstable signal transmission, and potentially short circuits. This can damage the connector and associated electronic equipment, affecting the operation of the automotive electronic system, causing safety hazards and increased maintenance costs. Therefore, based on the above problems, this invention provides a highly sealed automotive Ethernet connector to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a high-sealing automotive Ethernet connector. By setting up a dustproof component and a snap-fit ​​component, the dustproof component can not only improve the dustproof efficiency, but also directly prevent dust from entering the interface during the connector insertion and removal process; the snap-fit ​​component can not only quickly snap the interface, but also form a multi-locking mechanism with the dustproof component to further ensure the reliability of the connection. Through the above settings, the problem of dust entering the interface can be solved by the fact that although automotive connectors are inserted and removed infrequently, if the dust cap is not covered in time during maintenance and insertion / removal.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A high-sealing automotive Ethernet connector includes a first housing body and a second housing body, each having a sealing bellows sleeved at one end. A snap-fit ​​assembly is fixedly connected to the second housing body for assisting in locking the connector, and the snap-fit ​​assembly is connected to the second housing body. A dustproof assembly is also included for assisting in dust protection of the connector, and the dustproof assembly is connected to the first housing body.

[0006] Optionally, the snap-fit ​​assembly includes a sliding platform formed on the top of the second housing body, a second slider slidably connected to the sliding platform, a connecting groove symmetrically formed on the top of the second slider, elastic sheets symmetrically distributed fixedly connected to the inner wall of the connecting groove, and a circular clearance groove fixedly connected to the other end of the second housing body.

[0007] Optionally, the bottom of the second slider is fixedly connected with uniformly distributed positioning blocks, and the bottom of the sliding platform is provided with a second sliding groove corresponding to the position of the positioning blocks. The inner wall size of the second sliding groove is adapted to the outer contour size of the positioning blocks.

[0008] Optionally, the elastic sheet is a curved elastic structure, and the free end of the elastic sheet does not contact the inner wall of the connecting groove.

[0009] Optionally, the top height of the second slider is lower than the top height of the other end of the outer casing body, and the top of the other end of the outer casing body has a beveled structure.

[0010] Optionally, the dustproof assembly includes a dustproof curtain fixedly connected inside the main body of the outer shell. The dustproof curtain has uniformly distributed rectangular clearance grooves fixedly connected to it. The top of the main body of the outer shell is slidably connected to symmetrically distributed connecting rods. The top of the connecting rods is fixedly connected to a first slider. The top of the first slider is fixedly connected to the same push-pull handle. The side of the push-pull handle near the connecting rod is fixedly connected to a spring rod. The top of the main body of the outer shell is provided with a first sliding groove corresponding to the position of the connecting rod.

[0011] Optionally, the top of the dust curtain is fixedly connected to the interior of the outer casing body, and the remaining surfaces of the dust curtain are in a free-end state.

[0012] Optionally, the position of the first slide groove corresponds to the position of the rectangular clearance groove, the bottom of the connecting rod is on the same horizontal line as the bottom of the inner wall of the connecting groove, and the outer contour dimension of the first slider is larger than the inner wall contour dimension of the first slide groove.

[0013] Optionally, a male metal terminal is snapped into the interior of the first outer shell body, and a female metal terminal is snapped into the interior of the second outer shell body. A sealing pin is snapped into the end of both the male and female metal terminals near the sealing bellows. The male and female metal terminals cooperate with each other. A limiting block is fixedly connected to the top of the first outer shell body, and an elastic clip is fixedly connected to the top of the second outer shell body. The limiting block and the elastic clip cooperate with each other. A sealing element is sleeved on the second outer shell body near the sliding platform.

[0014] Optionally, the outer diameter of the connecting rod is adapted to the inner wall size of the connecting groove, the distance between the top of the other end of the second outer shell body and the top of the inner wall of the first outer shell body is greater than the outer thickness of the dust curtain, and the free end of the elastic rod is fixedly connected to one side of the limiting block.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up dustproof components and snap-fit ​​components, the dustproof components can not only improve the efficiency of dust prevention, but also directly prevent dust from entering the interface during the connector insertion and removal process, thereby avoiding the situation where dust enters the interface due to failure to cover the dustproof cover in time during maintenance and insertion / removal; the snap-fit ​​components can not only quickly snap the interface, but also form a multi-locking mechanism with the dustproof components, which can prevent the metal terminals from loosening during use and further ensure the reliability of the connection.

[0016] By setting a second slider, the sliding engagement of the positioning block and the second slide groove, the second slider can be slidably connected to the second outer shell body. The connecting rod and the second slider are engaged, so that the sliding of the connecting rod can drive the second slider to slide synchronously. This makes it convenient to move the second slider by stretching the push-pull handle, and facilitates switching between locking and unlocking the connector.

[0017] By setting up a spring rod and an elastic plate, and utilizing the elastic characteristics of the spring rod and the elastic plate, it is not only convenient for the push-pull handle to automatically reset after being stretched, but also makes the connection between the connecting rod and the second slider more secure and less likely to fall off. In addition, by utilizing the elastic force of the spring rod to restore, the push-pull handle needs to be continuously pulled by hand when plugging or unplugging, rather than being pulled out casually, thus physically avoiding the problem of accidental plugging or unplugging.

[0018] By using a dustproof curtain, rectangular clearance groove, and circular clearance groove in combination, the rectangular and circular clearance grooves exist in two states: when the outer shell body one and outer shell body two are tightly connected, the free end of the rectangular clearance groove bends towards the bottom of the inner wall of the outer shell body one, and the free end of the circular clearance groove bends towards the edge of the circular clearance groove. The deformation of the rectangular and circular clearance grooves achieves flexible clearance for the metal male terminal and connecting rod. When the outer shell body one and outer shell body two are separated, the rectangular and circular clearance grooves return to their original vertical state, facilitating dustproof treatment of the metal male and metal female terminals inside the outer shell body one and outer shell body two. In actual operation, the user can seamlessly switch between the above two states by plugging and unplugging, automatically preventing dust from entering the interface. Moreover, this dustproof method is not only simple in structure but also highly efficient, avoiding the situation where dust enters the interface due to failure to cover the dustproof cover in time during maintenance plugging and unplugging.

[0028] like Figures 1 to 10As shown, an embodiment of the present invention provides a high-sealing automotive Ethernet connector, including a housing body 1 and a housing body 2, wherein one end of both housing body 1 and housing body 2 is fitted with a sealing bellows 5 (e.g., Figure 1 As shown), a snap-fit ​​assembly is fixedly connected to the second outer shell body 2. The snap-fit ​​assembly is used to assist in locking the connector and is connected to the second outer shell body 2. A dustproof assembly is used to assist in dust protection for the connector and is connected to the first outer shell body 1. A metal male terminal 7 is snapped into the inside of the first outer shell body 1, and a metal female terminal 8 is snapped into the inside of the second outer shell body 2. A sealing pin 6 is snapped into the end of both the metal male terminal 7 and the metal female terminal 8 near the sealing bellows 5. The metal male terminal 7 and the metal female terminal 8 cooperate with each other. A limit block 3 is fixedly connected to the top of the first outer shell body 1, and an elastic clip 4 is fixedly connected to the top of the second outer shell body 2. The limit block 3 and the elastic clip 4 cooperate with each other. A sealing element 9 is sleeved on the second outer shell body 2 near the sliding platform 22 (e.g., Figures 2 to 3 As shown in the figure, the working principle of the metal male terminal 7 and the metal female terminal 8, the snap-fit ​​structure between the metal terminal and the housing body, and the specific connection method between the sealing bellows 5 and the housing body are disclosed as prior art, so they will not be described in detail. The high-sealing automotive Ethernet connector provided in this application is suitable for wire-to-wire scenarios such as automobiles that require waterproofing and vibration resistance, such as engine compartment and chassis wiring harness connections. The working principle of the Ethernet connector is disclosed as prior art, so it will not be described in detail. In actual products, the metal terminals achieve electrical conduction during operation, and the sealing structure isolates external moisture and dust. The locking device prevents loosening and ensures signal stability.

[0029] By incorporating dustproof and snap-fit ​​components, the dustproof component not only improves dustproof efficiency but also directly protects the inside of the interface from dust during connector insertion and removal, thus preventing dust from entering the interface due to failure to promptly cover the dustproof cover during maintenance. The snap-fit ​​component not only enables quick snap-fitting of the interface but also works in conjunction with the dustproof component to form multiple locking mechanisms, preventing metal terminals from loosening during use and further ensuring connection reliability.

[0030] As one implementation method in this embodiment, such as Figures 1 to 10As shown, the snap-fit ​​assembly includes a sliding platform 22 on the top of the outer shell body 2. A second slider 18 is slidably connected to the sliding platform 22. The bottom of the second slider 18 is fixedly connected to evenly distributed positioning blocks 19. A second groove 17 is provided at the bottom of the sliding platform 22 corresponding to the position of the positioning blocks 19. The inner wall size of the second groove 17 is adapted to the outer contour size of the positioning blocks 19. A connecting groove 20 is symmetrically provided on the top of the second slider 18. A symmetrically distributed elastic sheet 21 is fixedly connected to the inner wall of the connecting groove 20. The elastic sheet 21 is a curved elastic structure. The free end of the elastic sheet 21 does not contact the inner wall of the connecting groove 20. A circular clearance groove 16 is fixedly connected to the other end of the outer shell body 2. The top height of the second slider 18 is lower than the top height of the other end of the outer shell body 2. The top of the other end of the outer shell body 2 is a beveled structure.

[0031] Specifically, positioning block 19 has a structure that is wider at the bottom and narrower at the top (e.g., Figure 5 As shown), the inner contour of the second slide groove 17 is adapted to the outer contour of the positioning block 19, so that the positioning block 19 can slide smoothly along the long axis of the second slide groove 17. The second slide groove 17 is evenly distributed on the bottom of the inner wall of the sliding platform 22, and the position of the second slide groove 17 corresponds to the center of the adjacent metal female terminal 8 (e.g., Figure 4 As shown), to ensure that the sliding movement of the second slider 18 does not affect the mutual cooperation between the metal male terminal 7 and the metal female terminal 8, the other end of the outer shell body 2 is fixedly connected with circular clearance grooves 16 arranged in a circumferential array at the position corresponding to the position of the metal female terminal 8. The circular clearance grooves 16 are provided with cross-shaped grooves (such as...). Figure 4 As shown), the groove on the circular clearance groove 16 is connected to the channel of the internal snap-fit ​​metal female terminal 8 of the outer shell body 2. The outer shell body 2 is also fitted with a sealing element 9. The sealing element 9 can deform after being squeezed by external force. The outer contour dimension of the sealing element 9 is larger than the inner wall dimension of the other end of the outer shell body 1. However, when the outer shell body 1 and the outer shell body 2 are inserted and matched, the sealing element 9 can deform during insertion, so that the sealing element 9 can be retracted into the inner wall of the outer shell body 1. After the external force ends, the deformation is restored. The elastic recovery of the sealing element 9 ensures the connection seal between the outer shell body 1 and the outer shell body 2. Here, the elastic characteristics of the material are used to achieve the seal between the connectors. The specific structure and working principle are disclosed as prior art, so they will not be described in detail.

[0032] As one implementation method in this embodiment, such as Figures 1 to 10As shown, the dustproof assembly includes a dustproof curtain 10 fixedly connected inside the outer shell body 1. The top of the dustproof curtain 10 is fixedly connected to the interior of the outer shell body 1, and the remaining surfaces of the dustproof curtain 10 are in a free-end state. Evenly distributed rectangular clearance grooves 11 are fixedly connected to the dustproof curtain 10. Symmetrically distributed connecting rods 13 are slidably connected to the top of the outer shell body 1. A first slider 14 is fixedly connected to the top of the connecting rod 13. A push-pull handle 15 is fixedly connected to the top of the first slider 14. A spring rod 23 is fixedly connected to the side of the push-pull handle 15 near the connecting rod 13. A first groove 12 is provided at the top corresponding to the position of the connecting rod 13. The position of the first groove 12 corresponds to the position of the rectangular clearance groove 11. The bottom of the connecting rod 13 and the bottom of the inner wall of the connecting groove 20 are on the same horizontal line. The outer contour dimension of the first slider 14 is larger than the inner wall contour dimension of the first groove 12. The outer contour diameter dimension of the connecting rod 13 is adapted to the inner wall dimension of the connecting groove 20. The distance between the top of the other end of the outer shell body 2 and the top of the inner wall of the outer shell body 1 is larger than the outer contour thickness dimension of the dust curtain 10. The free end of the elastic rod 23 is fixedly connected to one side of the limiting block 3.

[0033] Furthermore, a rectangular clearance groove 11 is provided on the dust curtain 10 at the position corresponding to the metal male terminal 7, and the rectangular clearance groove 11 has a zigzag groove (such as...). Figure 3 As shown), the width of the rectangular clearance groove 11 is greater than the outer diameter of the insertion end of the metal male terminal 7, and the thickness of the rectangular clearance groove 11 is less than the thickness of the dust curtain 10. The dust curtain 10, the rectangular clearance groove 11, and the circular clearance groove 16 are all made of rubber. The position of the first sliding groove 12 corresponds one-to-one with the positions of the two middle rectangular clearance grooves 11 on the dust curtain 10 (e.g., Figure 3 As shown), the inner wall dimension of the first slide groove 12 is adapted to the outer contour dimension of the connecting rod 13, so that the connecting rod 13 can easily slide along the long axis direction of the first slide groove 12. One end of the elastic rod 23 is fixedly connected to the push-pull handle 15, and the other end of the elastic rod 23 is fixedly connected to the limiting block 3 (as shown). Figure 3 As shown), the elastic rod 23 itself has a certain elasticity, and can undergo elastic deformation when subjected to external force, and recover its deformation after the external force is released. The elastic rod 23 is a curved elastic wave-shaped structure. The dust curtain 10 is only fixedly connected to the inner wall of the outer shell body 1 at the top. During the process of the outer shell body 1 and the outer shell body 2 being inserted, the other end of the outer shell body 2 gradually approaches the dust curtain 10. When the side of the dust curtain 10 is squeezed by the outer shell body 2 when it is inserted, the dust curtain 10 will flip towards the side closer to the metal male terminal 7 (as shown). Figures 6 to 9As shown), when flipped upwards, the rectangular clearance groove 11 can flexibly avoid the connecting rod 13. Simultaneously, during the insertion process, the circular clearance groove 16 encounters the pressure of the metal male terminal 7, causing the free end of the circular clearance groove 16 to bend towards the edge of the circular clearance groove 16 (as shown). Figures 6 to 8 As shown), the circular clearance groove 16 is also used to flexibly avoid the metal male terminal 7. When it is snapped into place, the connecting rod 13 cooperates with the connecting groove 20 and the elastic piece 21 to achieve mutual snapping between the connecting rod 13 and the second slider 18. The bottom of the dust curtain 10 is located between the outer shell body 2 and the second slider 18, and the bottom height dimension of the dust curtain 10 is lower than the top height dimension of the outer shell body 2 (e.g., Figure 9 As shown, the bottom of the dust curtain 10 can limit the outer shell body 2, and the second slider 18 can also support the dust curtain 10. With the cooperation of the dust curtain 10, the second slider 18 and the outer shell body 2, the inner locking of the outer shell body 1 and the outer shell body 2 is realized. At the same time, the limiting block 3 will slide into the slot of the elastic clip 4. With the cooperation of the limiting block 3 and the elastic clip 4, the outer locking of the outer shell body 1 and the outer shell body 2 is realized, thereby realizing the multiple locking of the connector.

[0034] By setting the second slider 18, the positioning block 19, and the sliding engagement of the second slide groove 17, the second slider 18 can be slidably connected on the outer shell body 2. The connecting rod 13 engages with the second slider 18, so that the sliding of the connecting rod 13 can drive the second slider 18 to slide synchronously. This makes it convenient to move the second slider 18 by stretching the push-pull handle 15, and facilitates switching between locking and unlocking the connector. By setting the elastic rod 23 and the elastic plate 21, the elastic characteristics of the elastic rod 23 and the elastic plate 21 not only facilitate the automatic reset of the push-pull handle 15 after stretching, but also make the engagement between the connecting rod 13 and the second slider 18 more secure and less likely to fall off. Moreover, by utilizing the elasticity of the elastic rod 23, the push-pull handle 15 needs to be continuously pulled by hand when plugging and unplugging, rather than being pulled out casually, thus physically avoiding the problem of accidental plugging and unplugging.

[0035] Furthermore, when it is necessary to disconnect the connector, first pull the bottom of the elastic clip 4 upwards so that the limiting block 3 can be easily separated from the elastic clip 4. Then, pull the push handle 15 by hand towards the side closer to the sealing bellows 5. Since the connecting rod 13 and the second slider 18 are engaged at this time, the connecting rod 13 slides inside the first slide groove 12 by pulling the push handle 15, thereby driving the second slider 18 to slide. When the second slider 18 slides towards the other end of the outer shell body 2, the bottom of the dust curtain 10 will gradually rise with the sliding of the second slider 18 until the bottom height of the dust curtain 10 is higher than the top height of the other end of the outer shell body 2 (e.g., Figure 10As shown), the outer shell body 2 is then pulled outward. The force of pulling the outer shell body 2 outward also causes the second slider 18 to separate from the connecting rod 13, thus facilitating the complete separation of the outer shell body 2 from the outer shell body 1. After the outer shell body 2 separates from the outer shell body 1, the dust curtain 10 loses the pressure of the outer shell body 2, and the bottom of the dust curtain 10 will rotate downward, restoring the vertical state of the dust curtain 10. At this time, the rectangular clearance groove 11 also returns to the vertical state. By using the cooperation of the dust curtain 10 and the rectangular clearance groove 11, the internal separation of the outer shell body 1 is achieved. The metal male terminal 7 is located in the internal space formed by the dust curtain 10 and the outer shell body 1, which facilitates the dustproof treatment of the metal male terminal 7. After the outer shell body 2 separates from the outer shell body 1, the circular clearance groove 16 also loses the pressure of the metal male terminal 7 and returns to its original state. The circular clearance groove 16 can also be used to achieve dustproof treatment of the metal female terminal 8 inside the outer shell body 2.

[0036] By setting up a dustproof curtain 10, a rectangular clearance groove 11, and a circular clearance groove 16 in coordination, the rectangular clearance groove 11 and the circular clearance groove 16 exist in two states: when the outer shell body 1 and the outer shell body 2 are tightly connected, the free end of the rectangular clearance groove 11 bends towards the bottom of the inner wall of the outer shell body 1, and the free end of the circular clearance groove 16 bends towards the edge of the circular clearance groove 16. The deformation of the rectangular clearance groove 11 and the circular clearance groove 16 achieves flexible clearance of the metal male terminal 7 and the connecting rod 13. When the outer shell body 1... When 1 is separated from the outer shell body 2, the rectangular clearance groove 11 and the circular clearance groove 16 return to their original vertical state, which facilitates dust prevention of the metal male terminal 7 and metal female terminal 8 inside the outer shell body 1 and the outer shell body 2. In actual operation, the user can seamlessly switch between the above two states by plugging and unplugging, and automatically prevent the interface from getting dusty. Moreover, this dust prevention method is not only simple in structure, but also highly efficient, avoiding the situation where dust enters the interface due to failure to cover the dust cover in time during maintenance plugging and unplugging.

[0037] The working principle of the technical solution provided by this invention is as follows: During use, as the outer shell body 1 and outer shell body 2 are inserted, the other end of the outer shell body 2 gradually approaches the dust curtain 10. When the side of the dust curtain 10 is squeezed by the insertion of the outer shell body 2, the dust curtain 10 will flip towards the side closer to the metal male terminal 7. When it flips upward, it can flexibly avoid the connecting rod 13 using the rectangular avoidance groove 11. At the same time, during the insertion process, the circular avoidance groove 16 is squeezed by the metal male terminal 7, causing the free end of the circular avoidance groove 16 to bend towards the edge of the circular avoidance groove 16. Similarly, the circular avoidance groove 16 flexibly avoids the metal male terminal 7. When it is locked in place, the connecting rod 13 cooperates with the connecting groove 20 and the elastic piece 21 to realize the connection between the connecting rod 13 and the second slider 18. The dust curtain 10 is interlocked with the outer shell body 2, with its bottom positioned between the outer shell body 2 and the second slider 18. The bottom height of the dust curtain 10 is lower than the top height of the outer shell body 2. The bottom of the dust curtain 10 limits the movement of the outer shell body 2, while the second slider 18 supports it. The cooperation of the dust curtain 10, the second slider 18, and the outer shell body 2 achieves internal locking of the outer shell body 1 and the outer shell body 2. Simultaneously, the limiting block 3 slides into the slot of the elastic clip 4, achieving external locking of the outer shell body 1 and the outer shell body 2 through the cooperation of the limiting block 3 and the elastic clip 4. This results in multiple locking mechanisms for the connector. When the connector needs to be plugged in or unplugged, the bottom of the elastic clip 4 is first pulled upwards. This allows the limiting block 3 to easily separate from the elastic clamp 4. Then, by manually pulling the push-pull handle 15 towards the side closer to the sealing bellows 5, the connecting rod 13 and the second slider 18 are engaged. Pulling the push-pull handle 15 allows the connecting rod 13 to slide inside the first slide groove 12, thereby driving the second slider 18 to slide. As the second slider 18 slides towards the other end of the outer shell body 2, the bottom of the dust curtain 10 gradually rises with the sliding of the second slider 18 until the bottom height of the dust curtain 10 is higher than the top height of the other end of the outer shell body 2. Then, the outer shell body 2 is pulled outwards. The force of pulling the outer shell body 2 outwards also causes the second slider 18 to separate from the connecting rod 13, thus facilitating the separation of the outer shell body 2 from the outer shell body 5. After the complete separation of body 1 and outer shell body 2, the dust curtain 10 loses the pressure of outer shell body 2, and its bottom rotates downward, restoring its vertical state. At this time, the rectangular clearance groove 11 also returns to its vertical state. The internal separation of outer shell body 1 is achieved through the cooperation of the dust curtain 10 and the rectangular clearance groove 11. The metal male terminal 7 is located within the internal space formed by the dust curtain 10 and outer shell body 1, facilitating dustproofing of the metal male terminal 7. Similarly, after the separation of outer shell body 2 and outer shell body 1, the circular clearance groove 16 also loses the pressure of the metal male terminal 7 and returns to its original state. The circular clearance groove 16 can also be used to achieve dustproofing of the metal female terminal 8 inside outer shell body 2.Utilizing the elastic characteristics of the spring rod 23, not only is the automatic reset of the push-pull handle 15 after stretching convenient, but the elastic force of the spring rod 23 also allows for recovery. During insertion and removal, the push-pull handle 15 needs to be continuously pulled by hand, rather than being pulled out casually, thus physically avoiding the problem of accidental insertion and removal. The rectangular clearance groove 11 and the circular clearance groove 16 exist in two states: when the outer shell body 1 and the outer shell body 2 are tightly connected, the free end of the rectangular clearance groove 11 bends towards the bottom of the inner wall of the outer shell body 1, and the free end of the circular clearance groove 16 bends towards the edge of the circular clearance groove 16. The deformation of the rectangular clearance groove 11 and the circular clearance groove 16 achieves flexible clearance for the metal male terminal 7 and the connecting rod 13. When the outer shell body 1 and the outer shell body 2 are separated, the rectangular clearance groove 11 and the circular clearance groove 16 return to their original vertical state. This connector facilitates dustproofing of the metal male terminals 7 and metal female terminals 8 inside the outer shell body 1 and outer shell body 2. During actual operation, users can seamlessly switch between these two states using the insertion and removal action, automatically preventing dust from entering the interface. This dustproofing method is not only simple in structure but also highly efficient, preventing dust from entering the interface due to the failure to promptly cover the dust cover during maintenance. This connector not only improves dustproofing efficiency but also directly prevents dust from entering the interface during the insertion and removal process, thus avoiding dust entry due to the failure to promptly cover the dust cover during maintenance. It also allows for quick locking of the interface, and the various structures work together to form multiple locking mechanisms, preventing the metal terminals from loosening during use and further ensuring connection reliability.
