1, contact pieces, is the automotive connector to complete the electrical connection of the core components. Generally, the positive contact and the negative contact form a contact pair, and the electrical connection of the connector is completed by the mating of the male and female contacts. The positive contact is a rigid part in the form of a cylindrical (round pin), square (square pin) or flat (tab). Positive contacts are generally made of brass, phosphor bronze. The female contact, namely the socket, is the key part of the contact pair. It relies on the elastic structure to be elastically deformed when being engaged with the pin to produce the elastic force to make close contact with the positive contact to complete the connection. There are many types of jack structure, such as cylinder type (split slot, necking), tuning fork type, cantilever type (longitudinal slot), folding type (longitudinal slotted, 9 shape), box- As well as hyperbolic spring wire jack and so on.
2, the shell, also known as shell, is the car connector cover, which for the internal insulation mounting plate and pin to provide mechanical protection and provide plug and socket when the alignment of the adapter, and then fixed to the device connector .
3, insulators, insulators are often referred to as automotive connector base (base) or mounting plate (insert), its role is to make contact with the required position and spacing, and to ensure contact between contacts and contacts And the insulation between the shell properties. Good insulation resistance, voltage resistance and easy processing is the choice of insulating materials processed into the basic requirements of insulators.
4, accessories, accessories sub-structure of the annex and installation of accessories. Structural accessories such as rings, positioning keys, locating pins, guide pins, connecting rings, cable clamps, seals, gaskets and so on. Installation of accessories such as screws, nuts, screws, coils and so on. Annex most of the standard parts and common parts.
It is these four basic structural components to enable the automotive connector to act as a bridge, stable operation. With the rapid development of the automotive industry, various functional parts and various parts of the automobile are constantly developing towards intelligentization, refinement and reliability. The structural design, exterior design and materials of automobile connectors are also proposed. higher requirement.
