The inner side of the movable connection part 31 is abutted, and a limiting ring 311 is provided at the end of the floating connection part 31. The limiting ring 311 is used to limit the second contact part 42 to move in the floating connection part 31; the floating seat 2 is provided with a plug-in cavity 22, and the base 1 is provided with an assembly fixing cavity 12. The plug-in cavity 22 is opposite to the assembly fixing cavity 12. The power terminal 5 includes a pin portion 51, a fixing portion 52, a buffer portion 53 and a power connection portion 54 connected in sequence. The fixing portion 52 is provided in the assembly fixing cavity 12, and the pin portion 51 extends toward one side of the floating seat 2. The cross-section shape of the buffer portion 53 is U-shaped, and the two ends are respectively connected to the fixing portion 52 and the power connection portion 54, and one end of the power connection portion 54 extends into the plug-in cavity 22. In this embodiment, the base 1 and the floating seat 2 are independently formed of insulating materials, and the fixing member 3 and the floating connection member 4 are independently formed of conductive metal parts, which is not only convenient for production and assembly, but also can select the best material according to the functional characteristics of different components. The matching portion 11 of the base 1 and the matching groove 21 of the floating seat 2 are tightly connected and matched to ensure the relative position of the two is stable, laying the foundation for the stability of the structure of the entire connector. In the complex vibration environment of the vehicle, it can effectively prevent the components from loosening and ensure the reliable operation of the connector. The first contact portion 41 of the floating connector 4 is used for conductive connection to provide a path for signal transmission; the second contact portion 42 extends to the floating connection portion 31 and abuts against the inner side surface, and combined with the limiting ring 311 at the end of the floating connection portion 31, the second contact portion 42 is limited to move in the floating connection portion 31. The floating seat 2 is allowed to float within a certain range to compensate for the position deviation that may occur during the installation and use of the vehicle-mounted camera, and the stability of the conductive connection can be guaranteed to avoid poor contact problems caused by position changes, effectively improving the adaptability of the connector to different installation conditions. The pin portion 51 of the power terminal 5 extends toward one side of the floating seat 2, which is convenient for connection with the corresponding component of the vehicle-mounted camera. The fixing portion 52 is arranged in the assembly fixing cavity 12 to ensure the stable installation of the power terminal 5 on the base 1. The buffer portion 53 has a U-shaped cross section, and the unique shape provides the power terminal 5 with good buffering performance.During the driving process of the vehicle, vibration and impact will inevitably occur. The U-shaped buffer part 53 can absorb and disperse these external forces, prevent damage to the electrical connection part 54 caused by external force impact, extend the service life of the electrical terminal 5, and ensure the stability of signal transmission. One end of the electrical connection part 54 extends into the plug cavity 22, and achieves precise docking with the male connector of the vehicle-mounted camera, ensuring reliable electrical connection, ensuring that signals such as image data can be transmitted accurately and efficiently, and meeting the requirements of real-time and stable operation of the vehicle-mounted camera. This embodiment ensures various requirements of the vehicle-mounted camera in actual use. By optimizing the mechanical structure and electrical connection design, it performs well in terms of stability, adaptability and signal transmission reliability, providing a strong guarantee for the stable operation of the vehicle-mounted camera system.

[0024] See also Figure 7 As shown, the bottom surface of the base 1 is provided with a pin positioning groove 13, and the pin positioning groove 13 is used to position the pin portion 51, and the pin portion 51 extends to the outside of the pin positioning groove 13; a fixing groove 121 is provided on one side of the assembly fixing cavity 12, and assembly slides 122 are provided on both sides of the fixing groove 121, and assembly sliders 521 are provided on both sides of the fixing portion 52, and the assembly sliders 521 are slidably assembled on the assembly slides 122, and the assembly fixing cavity 12 is used to provide a space for the buffer portion 53 to move. In this embodiment, the pin positioning groove 13 accurately positions the pin portion 51, ensuring that the pin can quickly and accurately fall into the predetermined position during installation, greatly improving the convenience and stability of the connector assembly, and effectively reducing the probability of signal transmission failure caused by pin installation deviation. The matching design of the assembly slider 521 and the assembly slide 122 enables the fixing portion 52 to slide smoothly in the assembly fixing cavity 12. This not only provides the buffer part 53 with appropriate space for movement, but also effectively buffers the impact caused by vibration, bumps, etc. during vehicle driving, prevents the connection from loosening, and ensures the reliability of signal transmission. The synergy between the fixing groove 121 and the assembly slider 521 and the slide groove further enhances the overall structural stability of the connector. When facing a complex and changeable vehicle environment, the female connector can always maintain a good connection state, reducing the risk of connection failure due to external forces.

[0025] One end of the buffer portion 53 is close to the wall of the assembly and fixing cavity 12. When the buffer portion 53 is deformed under pressure, the end of the buffer portion 53 abuts against the wall of the assembly and fixing cavity 12 to limit the deformation of the buffer portion 53. In this embodiment, when vibration, impact and other conditions occur during the driving of the vehicle, the buffer portion 53 will be deformed under pressure. At this time, the end of the buffer portion 53 abuts against the wall of the assembly and fixing cavity 12 to accurately limit the deformation of the buffer portion 53. The performance failure problem caused by excessive deformation of the buffer portion 53 is effectively avoided. From the perspective of improving the overall performance of the female connector, this design greatly enhances the vibration resistance of the connector. In a frequently vibrating vehicle environment, the stability of the electrical connection can be stably maintained, reducing problems such as poor contact and signal interruption caused by vibration. Moreover, the limitation of the deformation of the buffer portion 53 prolongs the service life of the buffer portion 53 itself and the entire female connector, and reduces the maintenance cost and equipment downtime risk caused by premature damage to components.

[0026] A limiting inner ring 221 is provided at the end of the insertion cavity 22, and the limiting inner ring 221 is used to limit the end of the power connection part 54; a guiding inclined surface is provided at the end of the limiting inner ring 221; a retaining ring 23 is provided at the end of the floating seat 2, and the retaining ring 23 is used to limit the end of the floating connector 4. In this embodiment, the limiting inner ring 23 accurately limits the end of the power connection part 54, effectively ensuring the accurate position of the power connection part 54 during the plug-in process, greatly improving the stability and reliability of the electrical connection. The specially designed guiding inclined surface at its end can play a good guiding role during the plug-in operation, so that the power connection part 54 can be inserted into the plug-in cavity 22 more smoothly, significantly reducing the resistance and possible deviation during the insertion process, thereby improving the overall plug-in efficiency of the connector. The retaining ring 23 provided at the end of the floating seat 2 undertakes the key task of limiting the end of the floating connector 4. This design can effectively limit the movement range of the floating connector 4, ensuring that it always remains in a reasonable position range during normal operation, and avoiding affecting the performance of the connector due to excessive movement.

[0027] The axial direction of the mating portion 11 and the mating groove 21 are both circular; the end of the mating portion 11 facing the mating groove 21 is provided with a guiding bevel, and the mating groove 21 is provided with a mating bevel for guiding when the two are mating. In this embodiment, the circular axial shape is not only conducive to accurate positioning and docking during the installation process, reducing installation errors caused by shape deviations, but also enhancing the overall structural stability of the connector. The end of the mating portion 11 facing the mating groove 21 is carefully provided with a guiding bevel, and the mating groove 21 is correspondingly configured with a mating bevel. These two bevels play a key guiding role when the two are mating. When the connection operation is performed, the guiding bevel and the mating bevel interact with each other to guide the mating portion 11 to slide into the mating groove 21 accurately. This is particularly important in a vehicle-mounted environment, which has extremely high requirements for connection stability and reliability.

[0028] The base 1 is provided with a fixed platform 14, and fixed blocks 141 are provided on both sides of the fixed platform 14. A fixed card slot 142 is provided between the fixed block 141 and the fixed platform 14, and both sides of the fixing member 3 are clamped on the fixed card slot 142. Specifically, buckling grooves 143 are provided on both sides of the fixed platform 14, and buckling pieces 32 are provided on both sides of the fixing member 3. The buckling grooves 143 are provided on the bottom surface of the fixed platform 14, and the buckling pieces 32 are buckled on the buckling grooves 143. In this embodiment, the cooperation between the fixed block 141 and the fixed card slot 142 provides a stable installation foundation for the fixing member 3, ensuring that the fixing member 3 can remain stable in a complex vehicle environment, greatly enhancing the structural reliability of the connector as a whole. During the driving of the vehicle, it is inevitable that it will be affected by external forces such as vibration and bumps, and this stable connection method can effectively resist these external forces and reduce problems such as signal transmission interruption caused by loose connection. The design of the buckling groove 143 and the buckling piece 32 is icing on the cake. The buckle groove 143 is located on the bottom surface of the fixed platform 14, and the buckle piece 32 is precisely buckled with it, further optimizing the stability and sealing of the connection. On the one hand, it can prevent dust, water vapor and other impurities from invading the inside of the connector, avoid damage to electronic components, and extend the service life of the connector; on the other hand, the tight buckle design helps to improve the stability of signal transmission, ensuring that the image data collected by the vehicle camera can be accurately and quickly transmitted to related equipment, providing the driver with clear and reliable visual information and ensuring driving safety.

[0029] The bottom surface of the fixing member 3 is provided with a fixing welding piece 33, and the fixing welding piece 33 is provided in plurality, and the plurality of fixing welding pieces 33 are arranged in a circumferential direction on the periphery of the fixing member 3, and are used to fix the fixing member 3 to the board end. In this embodiment, the plurality of fixing welding pieces 33 arranged in a circumferential direction on the periphery of the fixing member 3 greatly enhances the stability of the connection between the fixing member 3 and the board end. In the complex driving environment of the vehicle, vibration and bumps are inevitable, and the plurality of fixing welding pieces 33 distributed in a circumferential direction can be uniformly stressed from different directions, effectively resisting the impact of external forces, ensuring that the fixing member 3 is always stably connected to the board end, avoiding the influence of signal transmission due to looseness, and ensuring the continuous and reliable operation of the vehicle-mounted camera.

[0030] The outer periphery of the floating seat 2 is provided with an assembly slot 24 and a positioning strip 25, and the floating connector 4 is provided with an assembly buckle 43 and a positioning slot 44. The positioning slot 44 is used to be clamped on the positioning strip 25 to position the floating connector 4 on the floating seat 2; the assembly buckle 43 is used to cooperate with the assembly slot 24 to position the floating connector 4 on the floating seat 2. In this embodiment, the design that the positioning slot 44 is clamped on the positioning strip 25 can accurately position the floating connector 4 on the floating seat 2. In the complex vibration environment of the vehicle, this positioning method effectively ensures the accuracy of the angle between the floating connector 4 and the floating seat 2 when connected, avoiding problems such as unstable signal transmission or poor contact due to angle deviation. At the same time, the close cooperation between the assembly buckle 43 and the assembly slot 24 further enhances the positioning effect of the floating connector 4 on the floating seat 2. This not only helps to improve the stability of the connection between the two and reduce the looseness that may be caused by vehicle bumps, but also provides operators with clear assembly instructions during the assembly process, greatly improving assembly efficiency and quality.

[0031] The assembly slot 24 and the positioning slot 44 are both long strip grooves to provide space for the floating seat 2 to move axially. In this embodiment, the design of the long strip groove enables the floating seat 2 to obtain precise and stable space when it moves axially, effectively ensuring the connection stability between the connector components. In a vehicle environment, vibrations and bumps are inevitable when the vehicle is driving. The floating seat 2 can be flexibly adjusted axially within the space provided by the assembly slot 24 and the positioning slot 44, thereby compensating for the position deviation of components caused by factors such as vibration, ensuring that the female connector and the board end of the vehicle camera always maintain a good electrical connection state, greatly reducing the risk of signal transmission interruption or instability.

[0032] The first contact portion 41 is arc-shaped and protrudes toward the outer periphery of the floating connector 4. The floating connector 4 is provided with a plurality of grooves to divide the first contact portion 41 into a plurality of parts. The section of the second contact portion 42 is formed in a V-shape, and one end is connected to the floating connector 4, and the other end is connected to a concave slope 421. A contact point 422 is formed between the concave slope 421 and the second contact portion 42 for contacting the fixed member 3. In this embodiment, the first contact portion 41 is arc-shaped and protrudes toward the outer periphery of the floating connector 4, and is divided into a plurality of parts by a plurality of grooves, which enhances the flexibility and stability of contact with the corresponding parts. The plurality of independent arc-shaped first contact portions 41 can better adapt to the slight deviation and vibration during the connection process, and can still ensure reliable electrical connection in the complex driving environment of the vehicle, and reduce the signal interruption phenomenon caused by looseness or poor contact. The unique V-shaped section design of the second contact portion 42, combined with one end connected to the floating connector 4 and the other end connected to the concave slope 421 to form a contact point 422 for contacting the fixed member 3, further improves the performance of the connector. The V-shaped section can effectively disperse the stress during connection and avoid damage to the connector caused by local stress concentration. The combination of the concave slope 421 and the contact point 422 makes the connection between the fixing part 3 and the female connector more stable, and also facilitates the connection and disassembly operations, ensuring that the mechanical and electrical properties of the connector remain in good condition under frequent plugging and unplugging, effectively ensuring the stable operation of the vehicle camera system.

[0033] Tight-fit buckles 541 are provided on both sides of the power connection part 54, and the tight-fit buckles 541 are used to fit the power connection part 54 tightly on the plug-in cavity 22; an elastic clamping part 542 is provided at one end of the power connection part 54, and the elastic clamping part 542 is arranged in a ring array with multiple intervals, and the end of the elastic clamping part 542 is provided with an introduction slope 543. In this embodiment, under the complex vibration environment and electrical interference conditions of the vehicle, it is ensured that the power connection part 54 and the plug-in cavity 22 are always tightly combined, and problems such as signal transmission interruption or poor contact caused by looseness are effectively avoided. Multiple elastic clamping parts 542 are distributed in a ring array at intervals. This layout method can not only firmly clamp the docking object in all directions, but also can be adaptively adjusted according to docking parts of different sizes, thereby enhancing the versatility and compatibility of the connector. The introduction slope 543 provided at the end of the elastic clamping part 542 further optimizes the docking process. During docking, the guide ramp 543 can guide the docking components to be inserted smoothly, reduce the difficulty of docking, improve docking efficiency, reduce the risk of component damage due to poor insertion, and further improve the performance of the vehicle camera board-end connector in actual applications.
