Automobile is an important travel tool in peoples life, wire harness as an important part of the car, plays an important role. Automobile wiring harness is mainly used for the internal connection of cars, instruments, batteries and circuits, which is characterized by cold resistance and high temperature resistance. The car wiring harness comes in multiple colors to distinguish the car circuits in maintenance. The manufacturing technology level of automobile wire harness directly affects the quality of automobile wire harness, so it is very important to increase the screening of connecting wire and the quality management of manufacturing. Therefore, the design of the automobile wiring harness should not only meet the performance requirements of the vehicle (such as temperature resistance, voltage resistance, etc.), but also meet the performance requirements of each wiring harness (such as reliable transmission of electrical signals). Due to the wide variety of wire harness materials and components constituting the vehicle safety, the manufacturing process is complicated and cumbersome, so the key to quality management is to control the manufacturing process according to the underlying failure mode and root cause analysis.
