If the crimping length is too short, the contact area between the terminal and the cable is likely to be too small, which cannot meet the crimp strength required by the automotive high-voltage wiring harness (that is, the retention force between the terminal and the cable), and at the same time, the electrical conductivity is too low. Therefore, the crimp length of the cable and the connector terminal must be strictly controlled.
In order to further understand the influence of the terminal structure, crimping method, crimping height, and crimping length in the crimping process technology on the electrical and mechanical properties of the automotive high-voltage wiring harness after crimping.
