The base and the floating seat are independently formed of insulating materials, and the fixing part and the floating connector are independently formed of conductive metal parts. This design not only ensures electrical isolation, but also realizes flexible conductive connection.

During the driving process of the vehicle, vibration and impact will inevitably occur. The U-shaped buffer part can effectively absorb these external forces, reduce the impact on the connecting part and the fixing part, and prevent the pin part from breaking or loosening due to vibration, greatly extending the service life of the connector. At the same time, the buffer part can also compensate for the slight position change between the pin part and the power connection part to a certain extent, ensuring that the two always maintain a good conductive connection state.

[0027] Efficient and convenient plug-in and assembly: The design of the plug-in cavity and the assembly fixing cavity relative to each other makes the plug-in process of the shell connector and the board-end connector more intuitive and convenient. During the assembly process, the operator can quickly and accurately dock the two, which improves the assembly efficiency. Moreover, this clear structural design is also conducive to later maintenance and repair work, reducing maintenance costs. In summary, the vehicle-mounted camera connector assembly achieves stable and reliable electrical connection, good floating compensation, buffer protection, and efficient and convenient assembly and maintenance through its unique structural design, which can meet the high-quality signal transmission requirements of vehicle-mounted cameras in complex vehicle environments.

[0040] One end of the buffer portion 83 is close to the wall of the assembly and fixing cavity 42. When the buffer portion 83 is deformed under pressure, the end of the buffer portion 83 abuts against the wall of the assembly and fixing cavity 42 to limit the deformation of the buffer portion 83. In this embodiment, during the driving of the vehicle, it is inevitably subjected to various vibrations and impacts. When these external forces are transmitted to the vehicle camera connector, the buffer portion 83 is deformed under pressure. The buffer portion 83 can be prevented from excessive deformation by abutting its end against the wall of the assembly and fixing cavity 42. This avoids extrusion, displacement or damage to key components such as internal circuits and chips due to excessive deformation, thereby ensuring that the connector works stably and reliably, and ensuring the stability and accuracy of the vehicle camera signal transmission. The overall durability of the connector is improved. The precise limit design allows the buffer portion 83 to remain within a reasonable range each time it is deformed by force, reducing material fatigue and aging caused by repeated excessive deformation of the buffer portion 83. This prolongs the service life of the buffer portion 83 and the entire vehicle-mounted camera connector assembly, and reduces the cost and maintenance workload caused by frequent replacement of connectors.

The buckle slots 443 are provided on the bottom surface of the fixed platform 44, and the buckle pieces 62 are buckled on the buckle slots 443. In this embodiment, the fixed platform 44 provided on the base 4 provides a stable basic support for the entire connector assembly, ensuring that it can still maintain a stable position under the complex vibration environment of the vehicle, reducing the problem of unstable connection caused by shaking. The design of the fixed blocks 441 and the fixed slots 442 on both sides of the fixed platform 44 enables the fixing member 6 to be accurately and firmly clamped in a specific position, enhances the mechanical stability of the overall structure, and effectively avoids the loosening of the fixing member 6 due to the bumps and vibrations during the driving of the vehicle, thereby ensuring the reliable connection between the vehicle-mounted camera connector and related equipment. The buckle groove 443 on the bottom surface of the fixing platform 44 cooperates with the buckle pieces 62 on both sides of the fixing member 6, further improving the stability and reliability of the connection. The buckle pieces 62 buckle on the buckle groove 443, which not only provides an additional positioning function, but also prevents the fixing member 6 from moving in the horizontal direction. This double fixing structure can optimize the electrical connection performance while ensuring the mechanical strength of the connector assembly. Because the stable connection structure can reduce interference and loss during signal transmission.

[0042] The outer periphery of the floating seat 5 is provided with an assembly slot 53 and a positioning strip 54, and the floating connector 7 is provided with an assembly buckle 73 and a positioning slot 74.

Specifically, the assembly slot 53 and the positioning slot 74 are both long strip-shaped grooves to provide a space for movement when the floating seat 5 moves axially. In this embodiment, the cooperation between the positioning slot 74 and the positioning strip 54 realizes precise directional positioning. This ensures that the floating connector 7 can be accurately in the preset position when installed on the floating seat 5, greatly improving the accuracy and consistency of assembly. In the complex electronic system environment on board, precise directional positioning is crucial to ensure the stability and reliability of the camera connector signal transmission, and effectively avoids signal transmission failures caused by directional deviation. The cooperation between the assembly buckle 73 and the assembly slot 53 further enhances the stability of the floating connector 7 on the floating seat 5. This cooperation method not only ensures the tightness of the two when connected, but also effectively prevents the floating connector 7 and the floating seat 5 from loosening or separation in the face of complex working conditions such as vibration and bumps during vehicle driving, thereby ensuring the connection quality of the connector assembly. The design of the long groove provides the necessary space for the axial movement of the floating seat 5. When the vehicle is running, due to factors such as temperature changes and body deformation, the vehicle-mounted camera connector may be subjected to certain axial stresses. The long groove allows the floating seat 5 to move axially within a certain range, thereby effectively buffering these stresses and reducing damage to the connector assembly caused by stress concentration.

The second contact portion 72 has a V-shaped cross section, one end of which is connected to the floating connector 7 and the other end is connected to the concave slope 721 to form a contact point 722 for contacting the fixing member 6. The V-shaped cross section can provide better elasticity and buffering performance. When facing the complex dynamic environment of the vehicle, it can absorb part of the impact force and prevent damage to the connector components due to rigid collision. The contact point 722 formed by the concave slope 721 and the second contact portion 72 is accurately positioned and tightly fits the fixing member 6, further optimizing the connection structure and ensuring that the vehicle-mounted camera can maintain a stable connection with the connector under various working conditions.
