Connectors are key electrical modules or units for connecting wire harnesses or electrical appliances, providing a convenient and reliable interface for electrical connections. These connectors are divided into plug connectors and socket connectors, including mating plug/socket terminals and plug/socket housings, and involve structural designs such as CPA, TPA, or PLR. Some sealing components may also be equipped with accessories such as sealing rings or sealing plugs.

With the rapid development of the automotive industry, various functional components and parts in automobiles are constantly evolving towards intelligence, refinement, and reliability, placing higher demands on the structural design, appearance design, and materials of automotive connectors.
