[Technical field]

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as a power source and integrate advanced technologies in vehicle power control and drive to form advanced technical principles, new technologies, and new structures. With the development of manufacturing technology, existing new energy vehicles have more and more functions. As the functions increase, there are more and more electrical parts in the car, which makes the number of wire harnesses used to connect electrical parts increase, resulting in more and more serious electromagnetic interference between wire harnesses. Most of the existing automotive wire harnesses are directly covered with a rubber protective layer on the outside of the wire core, which has poor buffering and shock resistance. As the car moves and bumps, the wire harness is prone to damage and breakage, causing car failures. [Contents of the utility model]
