Compared with traditional car connectors, connectors used for transmitting high-definition audio and video signals need to consider the integrity of high-frequency transmission signals and electromagnetic interference, while also ensuring mechanical reliability in the car environment.
The current transmission methods can be divided into three types: analog signals, digital signals, and optical signals, and all electrical connection technologies have supporting products and solutions. Among them, analog signals are mostly used for radio signals, GPS signals, and mobile network signals for antenna access; The application of digital signals is quite extensive, such as audio and video signals in cars, external interfaces such as USB and HDMI for consumer electronics, and the increasing number of camera signals in recent years; Optical signals, due to their extremely low transmission loss compared to electrical signals, are often used for high-end car audio and video transmission. The in car infotainment system generally includes: entertainment head unit, CD/DVD, antenna, front/rear display screen, consumer port, and camera. The main challenge in the development of car connectors is to simultaneously consider the mechanical and electrical performance of the product. The structural design of components often affects the impedance of the product, and the connection performance of components is determined by the structure. Therefore, stronger mechanical components and the highest electrical performance are the key characteristics that distinguish automotive connectors from other connector manufacturers in electrical connection technology.
At present, the main automotive connectors supplied by electric connection technology include but are not limited to Fakra series board end&wire end, HSD series board end&wire end, HD series, HSL, and car USB series.
