[0002] An automotive camera connector is an electronic component specifically designed to connect automotive cameras to other vehicle parts (such as in-vehicle displays and on-board computers). The automotive camera connector plays a crucial role in transmitting image signals. It accurately and stably transmits the high-definition video signals captured by the camera to the corresponding receiving device with extremely low latency, ensuring that the driver can obtain real-time and clear visual information about the vehicle's surroundings. Whether it's a reversing camera, a 360-degree panoramic view, or a forward traffic monitoring function used for driver assistance, all rely on the connector's reliable signal transmission.

[0003] In terms of structural design, vehicle camera connectors fully consider the complex and harsh operating environment of vehicles. They typically possess excellent waterproof, dustproof, shockproof, and electromagnetic interference resistance properties to ensure normal operation and maintain a stable connection under conditions such as high temperature, humidity, and bumps, preventing signal interruption or image quality degradation due to environmental factors.

[0026] The beneficial effects of this utility model are:

[0027] Compared with existing vehicle camera connectors, this utility model has the following technical advantages:

[0028] A robust and reliable power connection structure: The retaining plug in the connector housing securely fixes the power connection component within the housing, effectively preventing displacement due to vibration during vehicle operation. This ensures the stability of the first power connection terminal and guarantees a reliable connection with the second power connection terminal. The two ends of the first power connection terminal extend to the first and second insertion terminals respectively, forming a continuous and stable conductive path. This reduces contact resistance and signal transmission attenuation, improving the stability and reliability of the electrical connection and laying a solid foundation for the accurate transmission of vehicle camera signals.

[0029] Optimized floating connection design: The unique floating connection structure in the board-end connector is a major highlight. The base and floating seat are independently formed from insulating material, while the fixing component and floating connector are independently formed from conductive metal components. This design ensures both electrical isolation and flexible conductive connection. The connection method between the mating part and the mating groove allows the floating seat to float flexibly relative to the base, effectively compensating for connector mating position deviations caused by vehicle assembly errors, vibrations, and other factors. The first contact part of the floating connector is used for conductive connection, while the second contact part abuts against the inner side of the floating connector and is limited by a limiting ring. This design not only ensures good conductive contact of the floating connector during floating but also prevents it from disengaging, improving the stability and reliability of the connection.

[0030] Excellent buffering and protection performance: The buffer section of the second electrical terminal has a U-shaped cross-section, which provides excellent elasticity and buffering performance. During vehicle operation, vibrations and impacts are inevitable. The U-shaped buffer effectively absorbs these external forces, reducing the impact on the electrical and fixing parts, preventing the pins from breaking or loosening due to vibration, and significantly extending the connector's lifespan. Simultaneously, the buffer can also compensate for minor positional changes between the pins and the electrical connection, ensuring that they always maintain a good conductive connection.

[0031] Efficient and convenient mating and assembly: The design of the mating cavity and the assembly fixing cavity facing each other makes the mating process between the shell connector and the board-end connector more intuitive and convenient. During assembly, operators can quickly and accurately align the two, improving assembly efficiency. Moreover, this clear structural design also facilitates later maintenance and repair work, reducing maintenance costs. In summary, this automotive camera connector assembly, through its unique structural design, achieves a robust and reliable electrical connection, good float compensation, buffer protection, and efficient and convenient assembly and maintenance, meeting the high-quality signal transmission requirements of automotive cameras in complex vehicle environments.

The buffer part 83 has a U-shaped cross-section and its two ends are respectively connected to the fixing part 82 and the power-connecting part 84. One end of the power-connecting part 84 extends into the mating cavity 52. ​​The end of the floating connector 7 is inserted into the second mating end 23 so that the second contact part 72 contacts the inner wall of the second mating end 23. At the same time, the first power-connecting terminal 21 and the second power-connecting terminal 8 are electrically connected. This embodiment can produce the following technical effects:

[0050] A robust and reliable electrical connection structure: The retaining plug 3 in the housing connector 10 securely fixes the electrical connection component 2 within the housing 1, effectively preventing displacement of the electrical connection component 2 due to vibration during vehicle operation. This ensures the stability of the first electrical connection terminal 21 and guarantees its reliable connection with the second electrical connection terminal 8. The two ends of the first electrical connection terminal 21 extend to the first insertion end 22 and the second insertion end 23 respectively, forming a continuous and stable conductive path. This reduces contact resistance and signal transmission attenuation, improving the stability and reliability of the electrical connection and laying a solid foundation for the accurate transmission of vehicle camera signals.

[0051] Optimized floating connection design: The unique floating connection structure in the board-end connector 20 is a major highlight. The base 4 and floating seat 5 are independently formed from insulating material, while the fixing member 6 and floating connector 7 are independently formed from conductive metal parts. This design ensures both electrical isolation and flexible conductive connection. The connection method between the mating part 41 and the mating groove 51 allows the floating seat 5 to float flexibly relative to the base 4, effectively compensating for connector mating position deviations caused by vehicle assembly errors, vibrations, and other factors. The first contact part 71 of the floating connector 7 is used for conductive connection, and the second contact part 72 abuts against the inner side of the floating connection part 61 and is limited by the limiting ring 611. This design not only ensures that the floating connector 7 maintains good conductive contact during floating but also prevents it from detaching, improving the stability and reliability of the connection.

[0052] Excellent buffering and protection performance: The buffer portion 83 of the second electrical terminal 8 has a U-shaped cross-section, which provides excellent elasticity and buffering performance. During vehicle operation, vibrations and impacts are inevitable. The U-shaped buffer portion 83 can effectively absorb these external forces, reducing the impact on the electrical portion 84 and the fixing portion 82, preventing the pin portion 81 from breaking or loosening due to vibration, and greatly extending the service life of the connector. At the same time, the buffer portion 83 can also compensate for minor positional changes between the pin portion 81 and the electrical portion 84 to a certain extent, ensuring that the two always maintain a good conductive connection.

[0053] Efficient and convenient mating and assembly: The design of the mating cavity 52 and the assembly fixing cavity 42 opposite each other makes the mating process of the shell connector 10 and the board-end connector 20 more intuitive and convenient. During assembly, operators can quickly and accurately align the two, improving assembly efficiency. Moreover, this clear structural design also facilitates later maintenance and repair work, reducing maintenance costs.

The second plug portion 15 is provided with a fixing groove 151, and the fixing plug 3 is used to fix the limiting protrusion ring 243 in the fixing groove 151. In this embodiment, the layout of the power-connecting sleeve 24, the insulating component 25 and the first power-connecting terminal 21 achieves an effective combination of electrical connection and insulation protection. The insulating component 25 is set inside the power-connecting sleeve 24, which can reliably isolate the first power-connecting terminal 21 from the outside world, avoid the risk of short circuit, and ensure the stability and safety of current transmission, which is crucial for the normal operation of the vehicle camera in complex electrical environments. The design of the plug end 241, the fixing end 242 and the limiting protrusion ring 243 of the power-connecting sleeve 24 optimizes the assembly and positioning of the components. The fixing end 242 is set in the fixing cavity, and the limiting protrusion ring 243 realizes assembly limitation, so that the power-connecting sleeve 24 is accurately installed, ensuring the accuracy of the connection between the first plug portion 14 and other components, which is conducive to improving the connection stability of the entire vehicle camera connector assembly and reducing signal transmission failures caused by loosening.

The fixing groove 151 of the second plug portion 15, in conjunction with the fixing plug 3, fixes the limiting protrusion 243, further reinforcing the installation of the power receiving sleeve 24, improving the overall stability of the connector structure, and providing a solid guarantee for the stable operation of the vehicle-mounted camera.

[0057] See Figures 7-14As shown, the bottom surface of the base 4 is provided with a pin positioning groove 43, which is used to position the pin portion 81. The pin portion 81 extends to the outside of the pin positioning groove 43. A fixing groove 421 is provided on one side of the assembly fixing cavity 42, and assembly sliding grooves 422 are provided on both sides of the fixing groove 421. Assembly sliders 821 are provided on both sides of the fixing portion 82, and the assembly sliders 821 are slidably mounted on the assembly sliding grooves 422.

In this embodiment, the pin positioning groove 43 accurately positions the pin portion 81, ensuring that the pin is accurately positioned in the preset position during installation, greatly improving the accuracy and stability of connector assembly and effectively avoiding signal transmission failures caused by pin installation deviations. The pin portion 81 extends to the outside of the pin positioning groove 43, facilitating reliable connection with other components and ensuring the continuity of electrical signal transmission. The fixing groove 421 on one side of the mounting cavity 42 and the mounting slide grooves 422 on both sides cooperate with the mounting sliders 821 on both sides of the fixing part 82, producing a significant technical effect. The mounting sliders 821 can slide smoothly on the mounting slide grooves 422. This sliding assembly method not only facilitates the installation and disassembly of the buffer part 83 and improves assembly efficiency, but also allows the buffer part 83 to be securely installed in the mounting cavity 42. The movement space provided by the mounting cavity 42 for the buffer part 83 can effectively buffer the vibration and impact generated during vehicle operation, protect the precision structure inside the vehicle camera connector assembly, reduce damage to components caused by vibration, thereby extending the service life of the connector, ensuring that the camera can always maintain a stable and reliable connection with the vehicle system in complex vehicle environments, guaranteeing high-quality transmission of image data, and providing strong support for the stable operation of the vehicle camera system.

[0058] One end of the buffer portion 83 is close to the wall of the mounting cavity 42. When the buffer portion 83 is deformed under pressure, its end abuts against the wall of the mounting cavity 42 to limit the deformation of the buffer portion 83. In this embodiment, various vibrations and impacts are inevitable during vehicle operation. When these external forces are transmitted to the vehicle camera connector, the buffer portion 83 is deformed under pressure. By abutting its end against the wall of the mounting cavity 42, the buffer portion 83 is limited, preventing excessive deformation.
