In the next few years, China will become an important producing countries of the vehicle connector. The requirements of the automotive connector will also increase. According to the professional car connector agents in Guangzhou Hao Lung Liu engineers, automotive connectors four basic structural components.

1，a core part of the automotive connector to complete the electrical connection. Generally positive contacts and negative contacts parts composed of contacts, and Yin, the male contacts mating to complete the electrical connection. Positive contact with the rigid parts, its shape is cylindrical (round pin) square cylindrical (square pin) or flat (inserts). The positive contact is generally made of brass, phosphor bronze. Negative contact with parts namely jack, the exposure on the key parts, it relies on the elastic structure with the pin inserted timely elastic deformation of the elastic force of the positive contact in close contact to complete the connection. Jack structure of many types of cylinder (split groove, necking), tuning fork, cantilever-type (vertical slot), folding type (longitudinal slotted, 9 shaped), box-shaped (square socket) hyperboloid wire spring jack.

2, the shell, also known as the shell (the shell), the car connector housing, it provides mechanical protection for the built-in insulated mounting plate and pin, and plug and socket mated alignment, and then the connector fixed to the device.

3, Insulator, insulators, often called the car to connect the device base (base) or mounting plate (insert), its role is to make contact according to the required position and spacing arrangement, and to ensure contact and contact with the shell between the insulation performance. Good insulation resistance, withstand voltage performance and ease of processing is to choose the insulation material into the basic requirements of the insulator.

4, Annex, an annex to the structure of accessories and mounting accessories. Structural accessories such as collars, tabs, locating pin, guide pins, connecting ring, cable clamps, seals, gaskets, etc.. Install accessories such as screws, nuts, screws, coil etc.. Attachments have standard parts and common parts.
