[0002] With the rapid development of the automobile industry, the performance requirements for the internal electronic systems of automobiles are becoming higher and higher. Among them, automobile cables are an important component for connecting various electronic devices, and their performance directly affects the stability and safety of the entire automobile electronic system. However, under extreme weather conditions, such as in cold areas or when driving at high speeds, traditional automobile cables often lack cold resistance and become brittle and hard at extremely low temperatures, and are prone to breakage. At the same time, when subjected to tension during high-speed driving, they are also prone to deformation and loosening, resulting in unstable or even interrupted signal transmission. Therefore, we propose a cold-resistant and tensile-resistant automobile cable. Utility Model Content

The material used for the tensile layer is made of water-blocking fiber mixed in aramid fiber. Aramid fiber is a new type of synthetic fiber. The main function of aramid fiber is to provide strong tensile resistance and protect the cable from excessive stretching and twisting, thereby extending the service life of the cable. The utility model solves the problem that the existing automobile cables often have insufficient cold resistance, become brittle and hard at extremely low temperatures, and are prone to breakage; at the same time, when subjected to tension during high-speed driving, they are also prone to deformation and loosening.
