Four basic structure groups of automotive connectors

Automotive connectors act as the hub of bridges in automotive systems, and their stable and orderly work depends on the perfect cooperation of these four basic structural components. In view of the importance of automotive connectors, customers must select the components of connectors carefully, so as not to cause the collapse of the entire automotive system due to the error of one component. Facts have proved that only 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 have transferred processing industries to China. Some industry experts have analyzed that with the continuous transfer of foreign-funded enterprises to China and the continuous transfer of Chinese automotive connector enterprises. Strengthen research and development efforts and improve scientific and technological content, China will become an important producer of automotive connectors in the next few years. People's requirements for automotive connectors will also increase.

Contact parts are the core parts of automotive connectors to complete electrical connection functions. Generally, a contact pair is composed of a male contact and a female contact, and the electrical connection is completed by inserting the female and male contacts. The male contact is a rigid part that is cylindrical (round pin), square cylindrical (square pin) or flat (tab) in shape. The male contacts are generally made of brass and phosphor bronze. The female contact, that is, the socket, is the key part of the contact pair. It relies on the elastic deformation of the elastic structure when it is inserted with the pin to generate elastic force to form close contact with the male contact and complete the connection. There are many types of jack structures, including cylindrical type (splitting groove, shrinking notch), tuning fork type, cantilever beam type (longitudinal slotting), folding type (longitudinal slotting, figure 9 shape), box-shaped (square jack) and hyperboloid wire spring jack, etc. The shell, also known as the shell, is the outer cover of the automotive connector. It provides mechanical protection for the built-in insulating mounting plate and pins, and provides alignment when the plug and socket are plugged in, thereby fixing the connector to the device. Insulator, also often called automotive connector base (base) or mounting plate (insert), its function is to arrange the contacts according to the required position and spacing, and to ensure the insulation performance between the contacts and between the contacts and the shell. Good insulation resistance, voltage withstand performance and easy processability are the basic requirements for selecting insulating materials to be processed into insulators. Accessories, accessories are divided into structural accessories and installation accessories. Structural accessories such as clamping rings, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, sealing rings, gaskets, etc. Installation accessories such as screws, nuts, screws, spring coils, etc. Most accessories have standard parts and general parts.
