[0002] As a key communication component, the performance of Ethernet connectors directly affects the quality and stability of the car's network communication. However, traditional Ethernet connectors have many deficiencies in terms of shielding performance, connection stability, and ease of assembly and disassembly. For example, they often cannot effectively block external electromagnetic interference, resulting in unstable signal transmission; the connection part is easily loosened due to vibration during vehicle driving, affecting the continuity of communication; and the disassembly and assembly process is complicated, making it inconvenient to maintain and replace. These problems not only affect the normal operation of automotive electronic systems, but also bring many inconveniences to automakers and maintenance personnel. In the prior art, when the connector is connected to the socket, there is a gap, which will cause electromagnetic interference and affect the stability and integrity of signal transmission.

[0003] Therefore, there is an urgent need for a new type of high-shielded smart car Ethernet connector that can provide stable and reliable signal transmission in complex automotive environments and has convenient disassembly and assembly capabilities to meet the strict requirements of smart cars for high-speed, stable and reliable communication.

[0004] For example, the Chinese patent application number is 202411294601.8, the announcement date is 2024.11.26, and the classification number is H01R. It discloses a converter using magnetic principle Ethernet technology, including an outer conductor adapter, an insulator and a center conductor. The outer conductor adapter is sleeved on the outside of the center conductor, and there is an insulator between the center conductor and the outer conductor adapter. A male end slot is formed between one end of the outer conductor adapter and one end of the insulator for plugging a male head to an accessory. One end of the center conductor extends into the male end slot, and a female end slot is formed between the other end of the outer conductor adapter and the other end of the insulator for plugging a female head to an accessory. The other end of the center conductor extends into the female end slot, and a jack is coaxially provided. This structure is not only simple to operate and easy to install, but also avoids damage caused by excessive force during plugging, and improves the stability of data transmission.

When the control block 12 hits the marking block 11, the clamping block 24 will be aligned with the opening of the hook-shaped slot 25. The marking block 11 is fixed to the side of the connecting base 1. This design ensures the correct docking of the first shielding tube 9 and the second shielding tube 10, thereby improving the assembly accuracy of the connector.

[0025] In a specific embodiment of the present invention, first, when the connecting plug 2 is inserted into the interior of the connecting base 1, its connection will be wrapped by the connecting base 1 to form a sealed space, providing a first layer of shielding space, and the control block 12 is pushed to drive the second shielding cylinder 10 to rotate, so that the clamping block 24 is aligned with the opening of the hook-shaped slot 25, and the second shielding cylinder 10 can be slid into the first shielding cylinder 9, and then the second shielding cylinder 10 is rotated to make the clamping block 24 slide along the track of the hook-shaped slot 25, and when the second shielding cylinder 10 is rotated to the point where it cannot rotate, it is released, and the second shielding cylinder 10 is pushed back by the first spring 23 to make the clamping block 24 clamp into the locking part of the hook-shaped slot 25, forming a connection between the first shielding cylinder 9 and the second shielding cylinder 10, and at the same time, the material of the first shielding cylinder 9 and the second shielding cylinder 10 is conductive rubber, and the conductive filler in the conductive rubber, such as nano carbon tubes or metal particles, can improve its conductivity and shielding effect. Thereby effectively blocking external electromagnetic interference and forming a second layer of shielding effect. A sealing ring 35 made of rubber material is fixedly connected to the surface of the connecting plug 2, which can further increase the sealing between the connecting base 1 and the connecting plug 2, thereby further improving the shielding effect.

[0026] For details, please refer to Figure 6 , Figure 8 , Fig. 9 , Fig.10 The terminal assembly includes a first limiting sleeve 16, a second limiting sleeve 17, a first signal terminal 21, and a second signal terminal 22. The first limiting sleeve 16 and the second limiting sleeve 17 are fixedly connected to the second shielding block 15 and the first shielding block 6, respectively. A first wire 5 is passed through the first shielding block 6, and the first wire 5 passes through the second limiting sleeve 17 and one end is electrically connected and fixed to the second signal terminal 22. A second wire 13 is passed through the second shielding block 15, and the second wire 13 passes through the first limiting sleeve 16 and one end is electrically connected and fixed to the first signal terminal 21. The first signal terminal 21 and the second signal terminal 22 are fixed to the first limiting sleeve 16 and the second limiting sleeve 17, respectively. The end of the first signal terminal 21 is hook-shaped, and the end of the second signal terminal 22 is divided into an upper cylinder and a lower cylinder, and the upper cylinder and the lower cylinder are electrically connected. The lower cylinder is provided with a cavity electrically connected to the first signal terminal 21.

[0027] In this embodiment: in the process of realizing the connection and insertion of the first shielding cylinder 9 and the second shielding cylinder 10, the first signal terminal 21 and the second signal terminal 22 will complete the connection at the same time. Since the two first signal terminals 21 and the two second signal terminals 22 are mirror images of each other, in order to prevent the first signal terminal 21 and the second signal terminal 22 from interfering with each other when the second shielding cylinder 10 rotates, when the second shielding cylinder 10 slides toward the inside of the first shielding cylinder 9, the end of the first signal terminal 21 is set to the shape of a hook, and the end of the second signal terminal 22 is set to an upper cylinder and a lower cylinder, and a step structure is formed between the upper cylinder and the lower cylinder. The end of the first signal terminal 21 is hook-shaped, and the upper end of the second signal terminal 22 is hook-shaped. The step structure can form an avoidance for the first signal terminal 21 to be connected to the second signal terminal 22. In addition, the longitudinal length of the hook-shaped slot limits the distance that the first signal terminal 21 moves toward the second signal terminal 22, and the transverse section length of the hook-shaped slot limits the distance that the first signal terminal 21 can rotate. When the first signal terminal 21 moves from one end of the transverse section to the other end, the end of the first signal terminal 21 is just aligned with the second signal terminal 22. When the second shielding tube 10 is rotated to a position where it cannot rotate by the control block 12, the hook part of the first signal terminal 21 will be aligned with the second signal terminal 22, and then under the compression and rebound action of the first spring 23, the second shielding tube 10 will be pushed into the locking part of the hook-shaped slot 25. At the same time, the first signal terminal 21 is hooked into the lower cylinder cavity of the second signal terminal 22 to form a fixed connection, thereby ensuring the reliability of the connection between the first signal terminal 21 and the second signal terminal 22. Since the connection between the first signal terminal 21 and the second signal terminal 22 is located in the shielding space formed by the first shielding tube 9 and the second shielding tube 10, the shielding space will surround the exposed position of the connection between the two, so that the transmission line becomes a continuous shielding body, which improves the anti-interference ability against internal and external interference as a whole. At the same time, this connection method can absorb and alleviate the impact force generated by factors such as vibration during vehicle driving to a certain extent, and further improve the stability of the connection. In addition, the first shielding block 6 and the second shielding block 15 are made of rubber material, which increases the sealing performance and is waterproof and dustproof. The first limit sleeve 16 and the second limit sleeve 17 are used to limit the protection of the wire to prevent the wire from deviating in the first shielding tube 9 and the second shielding tube 10.

[0028] For details, please refer to Figure 1 and Figure 6 The connecting base 1 is provided with a combination groove on the side along the length direction, and the combination groove is used to connect with components other than the automotive Ethernet connector. A fixing groove is formed between the connecting plug 2 and the pressing plate 7, and the fixing groove is used to be plugged into the fixing plate on the car.

[0029] In this embodiment: the combination grooves of the connecting base 1 are centrally arranged by connecting with components of other automotive electronic systems, thereby improving the versatility and integration of the connector. While the connecting plug 2 and the connecting base 1 are stably connected through the snap-on assembly, the fixing groove formed between the connecting plug 2 and the pressing plate 7 will keep the connector stably fixed on the car after installation, reducing loose connection caused by vibration or impact, thereby improving the stability of signal transmission.

[0030] For details, please refer to Figure 6 The limiting assembly includes a limiting ring 19 and a limiting groove 20 . The limiting groove 20 is opened in the connecting base 1 . The limiting ring 19 is fixedly connected to the circumferential surface of the second shielding tube 10 . The limiting ring 19 is slidably connected to the inner wall of the limiting groove 20 .

[0031] In this embodiment, when the second shielding tube 10 moves, the limiting ring 19 moves in the limiting groove 20 to prevent the second shielding tube 10 from escaping from the connecting base 1 .

[0032] For details, please refer to Figure 1 and Figure 7 The buckle assembly includes a pressing plate 7, a first limiting block 8 and a locking hole 18. There are two first limiting blocks 8 and two locking holes 18. The pressing plate 7 is fixedly connected to the surface of the connecting plug 2. The two first limiting blocks 8 are fixedly connected to the surface of the pressing plate 7. The two locking holes 18 are opened on the surface of the connecting base 1. The two first limiting blocks 8 are matched with the two locking holes 18 respectively.

[0033] In this embodiment, the pressing plate 7 is made of polycarbonate, has very good elasticity, and is not easily damaged. By pressing the pressing plate 7 to make the first limit block 8 fit into the card hole 18, the connecting base 1 and the connecting plug 2 can be fixed.

[0034] The usage process of this embodiment is as follows: first, when the connecting plug 2 is inserted into the interior of the connecting base 1, the pressing plate 7 is made of polycarbonate, has very good elasticity, and is not easy to be damaged. By pressing the pressing plate 7 and making the first limit block 8 enter the card hole 18, the connecting base 1 and the connecting plug 2 can be fixed. The connection point will be wrapped by the connecting base 1 to form a sealed space to increase the shielding effect. The sealing ring 35 is made of rubber material, which can further increase the sealing between the connecting base 1 and the connecting plug 2, thereby further improving the sealing between the connecting base 1 and the connecting plug 2. By rotating the second shielding cylinder 10 through the control block 12 so that the clamping block 24 is aligned with the opening of the hook-shaped clamping groove 25, the second shielding cylinder 10 can be slid into the first shielding cylinder 9, and then the second shielding cylinder 10 is rotated so that the clamping block 24 slides along the trajectory of the hook-shaped clamping groove 25, and then the second shielding cylinder 10 will be pushed by the first spring 23 Go back a part so that the card block 24 is inserted into the hook-shaped card slot 25 to form a connection between the first shielding tube 9 and the second shielding tube 10. At the same time, the material of the first shielding tube 9 and the second shielding tube 10 is conductive rubber, which can effectively block external electromagnetic interference and form a second layer of shielding effect. In this process, the end hook of the first signal terminal 21 will also hook into the cavity of the lower cylinder of the second signal terminal 22 to form a docking fixation. Since the first shielding block 6 and the second shielding block 15 are made of rubber, they can be waterproof and dustproof, and the sealing of the connector is increased. The first limiting sleeve 16 and the second limiting sleeve 17 are used to limit and protect the wire to prevent the wire from deviating in the first shielding tube 9 and the second shielding tube 10; by using this device, multiple layers and sealed protection can be formed at the joint, thereby solving the problem that when the traditional connector is connected to the socket, there is a gap, which will cause electromagnetic interference and affect the stability and integrity of signal transmission.
