The composition and function of the connector. The connector, also known as the connector, consists of two parts, a plug and a socket, and is used for the connection between electrical equipment and lines and the connection between lines. Compared with the old-fashioned terminal single-wire connection method, the connector connection method has the advantages of convenient and fast wiring, simple and compact wiring harness structure, and avoids wiring errors. It has been widely used by modern cars. To ensure reliable connection, the connector is usually equipped with a lock Stop device, and has a good seal to prevent the entry of oil, water and dust to cause corrosion of the connector terminals.
Connector identification. The number of terminals, geometric dimensions and shapes of the connectors used in different positions on the car are different, and there is no wrong insertion. But modern cars use multiple line-to-line connectors, which may have the same number of terminals and shape. For this reason, the outer surface of some automotive wiring connectors is painted in various colors to facilitate troubleshooting and avoid connection errors.
