Pin arrangement for automotive connector and assembly control method
By combining a barbed structure with a cantilevered elastic arm structure for fixing, and with the precise assembly control of a servo press-fit system, the problems of loosening and micro-wear of automotive connectors in vibration environments are solved. This achieves stable axial locking and radial vibration prevention, improving the long-term stability of the connector and the quality inspection capabilities of automated assembly.

Abstract
The application relates to a row pin structure applied to an automobile connector and an assembly control method. The row pin structure comprises a plastic body and a conductive terminal with barbs. The body is provided with a clamping groove matched with the barbs and an inwardly extending cantilever-shaped elastic arm. After the terminal is inserted, a double fixing mechanism of mechanical interlocking and interference fit is formed. The application has the advantages of double fixing, anti-loosening and anti-terminal deformation. The assembly control method based on dynamic friction reference and contact stiffness verification can accurately identify false locking, quantify the fitting gap and monitor the risk of debris, thereby significantly improving the assembly quality and long-term reliability of the automobile connector.
