Automotive Connectors - Four Basic Structural Components
The four basic structural components of the automotive connector are as following：
1. The contact element. It is the core parts of the automotive connector to complete the electrical connection function. By the positive contact and the negative contact parts to form a contact pair, through the negative and positive contact parts of the plug to complete the electrical connection. Positive contact is a rigid part, its shape is cylindrical (round pin), square-shaped (square pin) or flat (insert). Positive contact parts are generally made of brass, phosphor bronze. The negative contact is the jack, is the key parts of the contact pair, it relies on the elastic structure of the pin in the insertion of elastic deformation and elastic force with the positive contact to form a close contact to complete the connection. Jack structure of many kinds, there are cylindrical (split groove, indentation), tuning fork type, cantilever beam type (longitudinal slotted), folded type (longitudinal slotted, 9 characters), box-shaped (square jack) and hyperbolic wire spring jack.
2.The shell, also known as the shell (shell), is the outer cover of the automotive connector, which provides mechanical protection for the insulated mounting plate and pins installed inside, and to provide alignment when the plug and socket are inserted, and then the connector is fixed to the equipment.
3. Insulator, which is also called automotive connector base (base) or mounting plate (insert), its role is to make contact with the required location and spacing arrangement, and to ensure that the contact between the parts and between the contact parts and the shell insulation performance. Good insulation resistance, voltage resistance and ease of processing is the choice of insulation materials processed into the basic requirements of the insulator.
4. Accessories. Accessories are divided into structural accessories and installation accessories. Structural accessories such as snap rings, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, sealing rings, gaskets, etc. Installation accessories such as screws, nuts, screws, spring rings, etc. Accessories are mostly available in standard and common parts. It is these four basic structural components that enable automotive connectors to act as a bridge and operate stably.
