Automotive connector is an electronic engineering and technical personnel often contact a component, its role is very simple, in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function, the car connector form and structure is ever changing, which is mainly composed of four basic structural components, respectively, Contacts, enclosures, insulators, accessories.

A, the contact part, is the core part of the automotive connector to complete the electrical connection function, generally composed of positive contact parts and negative contact parts contact pair, through the insertion of Yinyang contact parts to complete the electrical connection, positive contact parts are rigid parts, their shape is cylindrical, square column or flat shape, positive contact parts are generally made of brass, phosphorus bronze, negative contact parts are jacks, Is the key part of the contact pair, it relies on the elastic structure when the elastic deformation occurs and the elastic force is generated when the pin is inserted to form a close contact with the positive contact, to complete the connection, there are many types of jack structure, there are cylinder type, tuning fork type, cantilever beam type, folded type, box shape and hyperboloid wire spring jack.

Second, the housing, also known as the housing, is the outer cover of the automotive connector, which provides mechanical protection for the internal insulation mounting plate and pin, and provides alignment when the plug and socket are inserted, and then fixes the connector to the device.

Three, insulator, insulator is also known as the automotive connector base or installation plate, its role is to make the contact parts arranged according to the required position and spacing, and ensure the insulation performance between the contact parts and the contact parts and the shell, good insulation resistance, voltage resistance and easy processing is the basic requirements for the selection of insulating materials processed into insulators.

Four, accessories, accessories are divided into structural accessories and installation accessories, structural accessories such as clasp, positioning key, positioning pin, guide pin, connection ring, cable clamp, sealing ring, gasket, etc., installation accessories such as screws, nuts, screws, spring rings, etc., most of the accessories have standard parts and universal parts.

It is these four basic structural components that enable automotive connectors to act as Bridges and operate stably.
