[0003] First: Connection reliability needs improvement: Because vehicles experience various bumps and vibrations during driving, high-speed wiring harness connectors require good mechanical stability. However, some existing connectors may loosen or develop poor contact after prolonged use, affecting data and power transmission, leading to issues such as blurry images, stuttering, or control malfunctions, thus impacting driving safety.

[0004] Second: Large size: Some existing high-speed wiring harness connectors are quite large, which may take up too much space in the limited interior space of a car, causing inconvenience for installation and wiring. In addition, the large size may also affect the overall design and aesthetics of the electronic rearview mirror. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a high-speed wiring harness connector for electronic rearview mirrors in order to solve the problems existing in the prior art mentioned above.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a high-speed wiring harness connector for electronic rearview mirrors, including a connector body, wherein the wiring terminal of the connector body is connected to a cable, and the insertion end of the connector body has an inner hole, and a terminal assembly is installed at the middle position of the inner hole.

[0007] One side of the connector body is an arc-shaped side, and the other three sides are flat. One side of the plug end of the connector body is provided with an outwardly extending protrusion, which is directly opposite the arc-shaped side. The protrusion has a hollow structure.

[0008] The connector body has a notch on the side of the insertion end. The inner hole passes through the notch and the protrusion. The three sides of the notch extend outward to form an outer protrusion. The outer protrusion located on the protrusion contacts the inner wall of the protrusion. The protrusion, the outer protrusion and the connector body form a fan-shaped through hole.

[0009] The connector body has a cover on its side, and the cover and the protrusion are on the same side of the connector body. The cover is placed on the notch, and there is a gap between the cover and the protrusion.

[0010] Furthermore, the terminal assembly includes a connecting terminal and an insulator. The insulator is a hollow cylinder. The connecting terminal is located inside the insulator. Several guide posts are provided on the inner wall of the insulator. The guide posts are divided into a base and a triangular part. The tip of the triangular part faces the connecting terminal. The two sides of the triangular part are concave arc edges.

[0011] Furthermore, the inner hole is a round hole, and several outwardly extending grooves are formed on the inner wall of the inner hole.

[0012] Furthermore, the end of the cover away from the protrusion is an inclined end, the opening of the cover is provided with an inclined surface, and the inner side of the cover is provided with an extended side extending toward the outward protrusion, with a gap between the extended side and the outward protrusion.

[0013] Furthermore, the length of the notch is equal to the length of the inner hole.

[0014] Furthermore, the two sides of the protrusion are flush with the two sides of the connector body on the same side, and a through hole is provided in the middle of the protrusion.

[0015] Furthermore, arc-shaped grooves are provided on the symmetrical planes of the connector body.

[0016] Furthermore, the connector body has a notch and groove on its curved side surface, with the notch located in the middle and the groove arranged on both sides of the notch.

[0017] Furthermore, a U-shaped recess is provided along the bottom edge of the notch groove. The two ends of the U-shaped recess are sealed. The bottom of the U-shaped recess is an outwardly convex arc-shaped groove bottom. The bottom surface of the notch groove forms a long strip protrusion. An inner recess is provided on the long strip protrusion. The end face of the inner recess near the connector body is an inclined surface.

[0018] Furthermore, an annular groove is provided on the connector body, and the annular groove is located near the wiring terminal of the connector body.

[0019] The beneficial effects of this utility model are:

[0020] First, through the use of terminal assemblies, recessed inner holes, fan-shaped through holes, and protruding parts, an asymmetrical structure is designed to prevent mistake-proofing and ensure precise alignment of the guide pins. This meets the stringent requirements of electronic rearview mirrors for high-speed data transmission reliability and adaptability to the vehicle environment. Even when driving on bumpy roads, the connector maintains a stable connection, ensuring the stability and accuracy of data transmission and preventing loosening and poor contact. This not only ensures the continuity of data and power transmission, allowing the various functions of the electronic rearview mirror to operate stably, but also enhances the reliability of the entire automotive electronic system, reduces other system problems caused by connector failures, and provides drivers with more stable and reliable driving assistance support.

[0021] Secondly, connectors take up less space and are lighter inside the car, providing greater flexibility for the layout and installation of electronic rearview mirrors and other in-vehicle electronic devices. At the same time, miniaturized connectors also help optimize the overall design of the vehicle, making it more aesthetically pleasing and aligning with modern automotive design principles of compactness and efficient space utilization, thus enhancing the vehicle's market competitiveness.
