Compared with the traditional vehicle connector, the connector used to transmit high-definition audio and video signals needs to consider the signal integrity and electromagnetic interference of high-frequency transmission, and at the same time, ensure the mechanical reliability in the vehicle environment.

The current transmission mode can be divided into analog signal, digital signal and optical signal. Kehuatong has supporting products and solutions. Among them, analog signals are mostly used for radio signals, GPS signals and mobile network signals accessed by antennas; Digital signals are widely used, such as audio and video signals in the car, external USB and HDMI interfaces for consumer electronics, and camera signals that have been increasing in recent years; Optical signals are mostly used for high-end vehicle audio and video transmission because of their extremely low transmission loss compared with electrical signals. The on-board infotainment system generally includes: head unit, CD/DVD, antenna, front/rear display screen, consumer port, camera, etc. The main challenge of vehicle connector development is to give consideration to both the mechanical and electrical properties of the product. The structural design of parts often affects the product impedance, and the connection performance of parts is determined by the structure. Therefore, stronger mechanical components and the highest electrical performance are the key features that distinguish Kehuatong vehicle connector from other connector manufacturers.

At present, the main vehicle connectors supplied by Kehuatong include but are not limited to Fakra series board end&line end, HSD series board end&line end, HD series, HSL and vehicle USB series.
