Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, and in particular to an automotive surround-view radar video transmission wiring harness. Background Technology

[0002] With the rapid development of the automotive industry, people rely more heavily on cars for travel, making them an indispensable means of transportation in daily life. However, due to blind spots around cars, drivers often struggle to accurately identify all obstacles within these blind spots, including static and dynamic pedestrians, animals, and other vehicles, during starting, turning, and lane changes. This can easily lead to accidents. Therefore, surround-view radar is typically installed in cars to detect the surrounding environment and transmit the results to the center console screen for video playback. This process requires video transmission wiring harnesses. While existing video transmission harnesses for automotive surround-view radar can achieve video transmission, their connectors often only consider conductivity and lack robust mating designs. This leads to loosening of the connectors over time due to vibrations and bumps during driving.

[0003] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a video transmission harness for automotive surround-view radar that enables a more stable connection and avoids the phenomenon of loosening.
