I. Automotive connectors of the four basic structural components is how to 1. Contacts, is the automotive connector to complete the electrical connection function of the core parts. Generally by the positive contact and negative contact components composed of contact pairs, through the yin and yang contact parts of the insertion and completion of the electrical connection. Positive contacts for rigid parts, its shape for the cylindrical (round pin), square cylindrical (square pin) or flat (insert). Positive contacts are generally made of brass, phosphor bronze. Negative contact parts that jack, is the key parts of the contact pair, it relies on the elastic structure in the elastic deformation occurs with the pins when the elastic deformation and produce elastic force and the positive contact parts to form a close contact, complete the connection. Jack structure of many kinds, there are cylindrical (split groove, indentation), tuning fork type, cantilever beam type (longitudinal slot), folded type (longitudinal slot, 9-shaped), box-shaped (square jack) and hyperbolic wire spring jacks, etc. 2. Shell, also known as the shell (shell), is an automotive connector cover, it is mounted for the inner insulating mounting plate and pins to provide mechanical protection, and to provide the alignment of the plug and socket sockets, and thus the connector is fixed to the connector, and then the connector is not a good idea. 3. insulator, insulator is also often called automotive connector base (base) or mounting plate (insert), its role is to make contact with the required location and spacing, and to ensure that the contact between the contact and the contact and the insulation between the shell. Good insulation resistance, voltage resistance and easy processing is the choice of insulating materials processed into the basic requirements of the insulator. 4. accessories, accessories sub-structural accessories and installation accessories. Structural accessories such as rings, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, seals, gaskets and so on. Installation accessories such as screws, nuts, screws, spring rings and so on. Most of the accessories are standard and general-purpose parts.
