At present, the connector terminal structure commonly used in automotive high-voltage wiring harnesses. The terminal structure can be divided into contact section, middle section and crimping section. The contact section is used to ensure the connection of the connector, the transmission of electrical power and signals; the middle section is the receiving area between the contact section and the crimping section, ensuring that the contact section and itself are not deformed during the crimping process, and at the same time play a role in positioning. Once the deformation occurs during the crimping process, it will seriously affect the performance of the automobile wiring harness; the crimping section is used to connect the contact surface of the connector terminal and the cable under external force, and its quality directly affects the electrical conductivity, pull-off force, etc. of the automobile wiring harness.
