Description

Technical Field

[0001] The present invention belongs to the technical field of connection devices, and particularly relates to a high-shielding intelligent vehicle Ethernet connector. Background Art

[0002] As a key communication component, the performance of an Ethernet connector directly affects the network communication quality and stability of a vehicle. However, traditional Ethernet connectors have many deficiencies in aspects such as shielding performance, connection stability, and disassembly and assembly convenience. For example, they often cannot effectively block external electromagnetic interference, resulting in unstable signal transmission; the connection part is prone to looseness due to vibrations during vehicle driving, affecting the continuity of communication; and the disassembly and assembly process is complex, making it inconvenient for maintenance and replacement. These problems not only affect the normal operation of vehicle electronic systems but also bring many inconveniences to vehicle manufacturers and maintenance personnel. In the prior art, when a connector is connected to a socket, there are gaps, which can 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-shielding intelligent vehicle Ethernet connector that can provide stable and reliable signal transmission in a complex vehicle environment and at the same time has convenient disassembly and assembly performance to meet the strict requirements of intelligent vehicles for high-speed, stable, and reliable communication.

[0004] For example, Chinese Patent Application No. is 202411294601.8, the publication date is November 26, 2024, and the classification number is H01R. It discloses an adapter using magnetic principle Ethernet technology, including an outer guide adapter body, an insulator, and a central conductor. The outer guide adapter body is sleeved outside the central conductor, and there is an insulator between the central conductor and the outer guide adapter body. A male end slot is formed between one end of the outer guide adapter body and one end of the insulator for plugging a male head pair fitting. One end of the central conductor extends into the male end slot. A female end slot is formed between the other end of the outer guide adapter body and the other end of the insulator for plugging a female head pair fitting. The other end of the central conductor extends into the female end slot and is coaxially provided with a jack. This structure is not only simple to operate and convenient to install but also avoids damage caused by excessive force during mating, improving the stability of data transmission.

[0005] In the above literature, only a sleeve structure is used to achieve shielding, and the shielding function is not good. Moreover, for the clamping connection, it is only achieved through the clamping members at both ends, and the clamping members are arranged along the length direction of the clamping members. Also, the connection direction of the cable wire and the electrical connector is also along the length direction of the clamping members, resulting in poor connection reliability between the cable wire and the electrical connector.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1.

[0038] Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9, Figure 10 , the present invention provides the following technical solutions:

[0039] A high-shielding intelligent automotive Ethernet connector, comprising:

[0040] A connection base 1, in which a limiting component is provided;

[0041] A connection plug 2, the docking of the connection plug 2 and the connection base 1 is locked by a snap component;

[0042] A sleeve shielding component, the sleeve shielding component includes a first shielding block 6, a first shielding cylinder 9, a second shielding cylinder 10, a second shielding block 15, a first spring 23, a clamping block 24 and a hook-shaped card slot 25. The first shielding cylinder 9 is arranged in the central through hole of the connection plug 2 and its length is equal to the length of the central through hole. One end of the second shielding cylinder 10 extends into the first shielding cylinder 9, and the other end of the second shielding cylinder 10 is rotatably arranged in the connection base 1. The first shielding block 6 is fixedly connected to the inner wall of the first shielding cylinder 9 and one end abuts against the first spring 23. The other end of the first spring 23 abuts against the end of the second shielding cylinder 10 extending into the first shielding cylinder 9. The clamping block 24 is fixed on the circumferential surface of the second shielding cylinder 10 and can slide along the track of the hook-shaped card slot 25. The hook-shaped card slot 25 is opened along the circumferential inner wall of the first shielding cylinder 9 and one end is provided with an opening. When the clamping block 24 enters along the opening and reaches the bottom of the hook-shaped card slot 25, rotate the second shielding cylinder 10 until it cannot rotate. At this time, the first spring 23 is in a compressed state. Then release the rotation of the second shielding cylinder 10, and the rebound of the first spring 23 will cause the clamping block 24 to be stuck into the locking part of the hook-shaped card slot 25 to complete the docking of the first shielding cylinder 9 and the second shielding cylinder 10;

[0043] A disassembly and assembly component, the disassembly and assembly component is arranged on one side of the connection base 1;

[0044] A sealing ring 35 is fixedly connected to the surface of the connection plug 2, and a control block 12 is fixedly connected to the surface of the second shielding cylinder 10. When the control block 12 touches the marking block 11, the clamping block 24 will be aligned with the opening of the hook-shaped card slot 25. The marking block 11 is fixed on the side surface of the connection base 1. This design ensures the correct docking of the first shielding cylinder 9 and the second shielding cylinder 10 and improves the assembly accuracy of the connector.

[0045] 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.

[0046] For details, please refer to Figure 6 , Figure 8 , Figure 9 , Figure 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.

[0047] In this embodiment: During the process of connecting and snapping the first shielding cylinder 9 and the second shielding cylinder 10, the first signal terminal 21 and the second signal terminal 22 will be connected simultaneously. Since the two first signal terminals 21 and the two second signal terminals 22 are mirror images of each other, in order to prevent movement interference between the first signal terminal 21 and the second signal terminal 22 when the second shielding cylinder 10 rotates, when the second shielding cylinder 10 slides into the interior of the first shielding cylinder 9, the end of the first signal terminal 21 is set in the shape of a hook, and the end of the second signal terminal 22 is set as an upper cylinder body and a lower cylinder body, and a stepped structure is formed between the upper cylinder body and the lower cylinder body. The end of the first signal terminal 21 is hook-shaped, and the stepped structure on the second signal terminal 22 can provide an avoidance for the connection of the first signal terminal 21 to the second signal terminal 22. In addition, the longitudinal length of the hook-shaped card slot limits the distance that the first signal terminal 21 moves towards the second signal terminal 22, and the transverse section length of the hook-shaped card 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 just aligns with the second signal terminal 22. When the second shielding cylinder 10 is rotated by the control block 12 to a non-rotatable position, at this time, the hook part of the first signal terminal 21 will align with the second signal terminal 22, and then under the compression and rebound action of the first spring 23, the second shielding cylinder 10 will be pushed into the locking part of the hook-shaped card slot 25. And at the same time, the first signal terminal 21 will be hooked into the cavity of the lower cylinder body of the second signal terminal 22 to form a fixation, thereby ensuring the reliability of the connection between the first signal terminal 21 and the second signal terminal 22. Since the connection part of the first signal terminal 21 and the second signal terminal 22 is located in the shielding space formed by the first shielding cylinder 9 and the second shielding cylinder 10 at this time, this shielding space will surround the exposed position of their connection, making the transmission line a continuous shielding body, which overall improves the anti-interference ability against internal and external interference. At the same time, this connection method can, to a certain extent, absorb and relieve the impact force generated by factors such as vehicle vibration during vehicle driving on the connection part, further improving the connection stability. In addition, the first shielding block 6 and the second shielding block 15 are made of rubber material, which increases the sealing performance and can prevent water and dust. The first limiting sleeve 16 and the second limiting sleeve 17 are used to limit and protect the wire to prevent the wire from shifting inside the first shielding cylinder 9 and the second shielding cylinder 10.

[0048] For details, please refer to Figure 1 and Figure 6 A combined slot is provided on the side surface of the connection base 1 along the length direction, and the combined slot is used to connect components other than the automotive Ethernet connector. A fixing slot is formed between the connection plug 2 and the pressing plate 7, and the fixing slot is used to be inserted into the fixing plate on the vehicle.

[0049] In this embodiment: The combined slot of the connection base 1 is connected to components of other automotive electronic systems to complete centralized arrangement, improving the versatility and integration of the connector. While the connection plug 2 is stably connected to the connection base 1 through the buckle assembly, the fixing slot formed between the connection plug 2 and the pressing plate 7 will maintain the stable fixation of the connector on the vehicle after installation, reducing connection looseness caused by vibration or impact, thereby improving the stability of signal transmission.

[0050] Specifically, please refer to Figure 6 , the limiting component includes a limiting ring 19 and a limiting slot 20. The limiting slot 20 is opened in the connection base 1, the limiting ring 19 is fixedly connected to the circumferential surface of the second shielding cylinder 10, and the limiting ring 19 is slidably connected to the inner wall of the limiting slot 20.

[0051] In this embodiment: When the second shielding cylinder 10 moves, the limiting ring 19 will move in the limiting slot 20 to prevent the second shielding cylinder 10 from being disengaged from the connection base 1.

[0052] Specifically, please refer to Figure 1 and Figure 7 , the buckle assembly includes a pressing plate 7, a first limiting block 8 and a card hole 18. There are two first limiting blocks 8 and two card holes 18. The pressing plate 7 is fixedly connected to the surface of the connection plug 2, the two first limiting blocks 8 are fixedly connected to the surface of the pressing plate 7, the two card holes 18 are opened on the surface of the connection base 1, and the two first limiting blocks 8 respectively match the two card holes 18.

[0053] 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, the first limiting block 8 can be snapped into the card hole 18 to fix the connection base 1 and the connection plug 2.

[0054] Usage process of this embodiment: First, after the connection plug 2 is snapped into the interior of the connection base 1, the pressing plate 7 is made of polycarbonate, has very good elasticity, and is not easily damaged. By pressing the pressing plate 7, the first limiting block 8 is snapped into the card hole 18, and then the connection base 1 and the connection plug 2 can be fixed. Their connection part will be wrapped by the connection base 1 to form a sealed space, increasing the shielding effect. The sealing ring 35 is made of rubber material, which can further increase the sealing performance between the connection base 1 and the connection plug 2, thus further improving the sealing performance of the connection base 1 and the connection plug 2. By rotating the second shielding cylinder 10 with the control block 12 to align the clamping block 24 with the opening of the hook-shaped card slot 25, the second shielding cylinder 10 can be slid into the first shielding cylinder 9. Then, rotate the second shielding cylinder 10 to make the clamping block 24 slide along the track of the hook-shaped card slot 25. Then, the second shielding cylinder 10 will be pushed back a part by the first spring 23, making the clamping block 24 snap into the hook-shaped card slot 25 to form the connection between the first shielding cylinder 9 and the second shielding cylinder 10. At the same time, the materials of the first shielding cylinder 9 and the second shielding cylinder 10 are conductive rubber, which can effectively block external electromagnetic interference and form a second-layer shielding effect. During 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 butt joint fixation. Since the first shielding block 6 and the second shielding block 15 are made of rubber material, they can prevent water and dust, increasing the sealing performance of the connector. The first limiting sleeve 16 and the second limiting sleeve 17 are used to limit and protect the wire to prevent the wire from shifting inside the first shielding cylinder 9 and the second shielding cylinder 10. By using this device, multiple-layer and sealed protection can be formed at the connection, thus solving the problem that there are gaps when the traditional connector is connected to the socket, which will cause electromagnetic interference and affect the stability and integrity of signal transmission.

The two second limiting blocks 32 are both slidably connected to the inner wall of the sliding groove 14.

[0057] In this embodiment: By rotating the threaded rod 26, the two threaded blocks 27 move in a closer direction. Then the sliding rod 29 will be squeezed into the rotating component 28. Then the second limiting block 32 will be stuck into the sliding groove 14. At this time, the device can be installed on the wire harness support plate 4, realizing the convenient disassembly and assembly of the connector, facilitating maintenance and replacement, and ensuring the stability and reliability of the connector during long-term use.

[0062] Specifically, please refer to Figure 5 , the thread directions between the two threaded blocks 27 are set in opposite directions.

[0063] In this embodiment: When the threaded rod 26 rotates, the threads between the two threaded blocks 27 are opposite, so that the two threaded blocks 27 can move in opposite directions to achieve the disassembly and assembly effect of the disassembly and assembly component.
