Four basic structural components of automotive connectors - contact parts

Contact: It is the core component of the automotive connector to complete the electrical connection function. The contact pair is generally composed of a male contact and a female contact, and the electrical connection is completed by the insertion of the female and male contacts.

The male contact is a rigid part that is cylindrical (round pin), square (square pin) or flat (tab). Positive contacts are typically made of brass or phosphor bronze. The female contact, that is, the jack, is a key component of the contact pair. It relies on the elastic structure to elastically deform when it is inserted into the pin, and generates elastic force to form close contact with the male contact member to complete the connection. There are many types of jacks, such as cylindrical (grooving, shrinking), tuning fork type, cantilever beam type (longitudinal slotting), folding type (longitudinal slotting, 9-shaped), box shape (square socket) And a double-curved wire spring jack.
