Automotive connector in the automotive system acts as a bridge hub role, its stable and orderly work depends on the perfect cooperation of these four basic structural components, in view of the importance of automotive connectors, customers in the selection of connector components, be sure to select carefully, do not cause a component failure to lead to the collapse of the entire automotive system. It has been proven that good components can create superior automotive connectors and ensure the safe and orderly operation of automotive systems.

With the expansion of overseas markets and the trend of economic globalization, more and more countries will transfer the processing industry to China, some industry experts said that foreign enterprises continue to transfer to China, and China's auto connector companies continue to strengthen research and development efforts to improve the scientific and technological content, in the next few years, China will become an important production country of auto connectors. People's requirements for car connectors will also increase.
The contact part is the core part of the automobile connector to complete the electrical connection function. Generally, the contact pair is composed of positive contacts and negative contacts, and the electrical connection is completed through the insertion of Yin and Yang contacts. The positive contact is a rigid part with a cylindrical shape (round pin), a square column shape (square pin) or a flat shape (insert). Positive contacts are generally made of brass or phosphor bronze. The negative contact part is the jack, which is the key part of the contact pair. It relies on the elastic deformation of the elastic structure when inserting the pin and generates the elastic force to form close contact with the positive contact part to complete the connection. There are many types of jack structures, such as cylinder type (split slot, reduced mouth), tuning fork type, cantilever beam type (longitudinal slot), folded type (longitudinal slot, figure 9), box shape (square jack) and hyperbolic wire spring jack.
The housing, also known as the shell, is the outer cover of the automotive connector, which provides mechanical protection for the internal insulation mounting plate and pins, and provides alignment when the plug and socket are inserted, thereby securing the connector to the device. Insulator, insulator is also often referred to as the automotive connector base (base) or mounting plate (insert), its role is to make the contacts arranged according to the required position and spacing, and ensure the insulation performance between the contacts and the contact between the shell. Good insulation resistance, voltage resistance and machinability are the basic requirements for selecting insulating materials for processing into insulators.
Accessories, accessories are divided into structural accessories and installation accessories. Structural accessories such as fasteners, positioning keys, positioning pins, guide pins, connecting rings, cable clamps, sealing rings, gaskets, etc. Mounting accessories such as screws, nuts, screws, spring rings, etc. Most accessories have standard parts and universal parts.
