Before explaining, what is your understanding of car connectors? As the name suggests, it is a component that transmits current to connect the car, but not only that, then let's talk about its basic knowledge.

Automotive connectors are a component that electronic engineering technicians often touch. Its function is very simple: it sets up a bridge of communication between the blocked or isolated circuits in the circuit, so that the current flows and the circuit achieves the predetermined function. The form and structure of automotive connectors are ever-changing, and they are mainly composed of four basic structural components, namely: contacts, shells (depending on the variety), insulators, and accessories. In the industry, it is usually also called sheath, connector, plastic shell.

 

About Automotive Connectors

      There are nearly 100 types of connectors used in general cars, and there are hundreds of connectors used in a single model. As people have higher and higher requirements for safety, environmental protection, comfort, and intelligence in automobiles, the application of automotive electronic products is increasing, which will increase the number of automotive connector applications.

 

basic structure

Four basic structural components of automotive connectors

      1. the contact piece is the core part of the automobile connector to complete the electrical connection function. Generally, a contact pair is formed by a male contact piece and a female contact piece, and the electrical connection is completed by the insertion of the female contact piece and the male contact piece.

The male contact is a rigid part, and its shape is cylindrical (round pin), square column (square pin) or flat (insert). The male contacts are generally made of brass and phosphor bronze. The female contact piece is the jack, which is the key part of the contact pair. It relies on the elastic structure to elastically deform when it is inserted into the pin to generate an elastic force to form a close contact with the male contact piece to complete the connection. There are many types of jack structures, including cylindrical type (split slot, necking), tuning fork type, cantilever beam type (longitudinal slotting), folding type (longitudinal slotting, 9-shaped), box-shaped (square jack) As well as hyperboloid wire spring jacks and so on.

       2, 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 inserted, thereby fixing the connector. to the device.

       3, insulators, insulators are also often referred to as automobile connector bases or inserts. Its function is to arrange the contacts according to the required position and spacing, and to ensure the Insulation performance with the shell. Good insulation resistance, withstand voltage performance and ease of processing are the basic requirements for selecting insulating materials to be processed into insulators.

      4, accessories, accessories are divided into structural accessories and installation accessories. Structural accessories such as retaining rings, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, sealing rings, gaskets, etc. Mounting accessories such as screws, nuts, screws, spring rings, etc. Most of the accessories have standard parts and general parts.

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

development trend

        At present, the global automotive connector accounts for about 15% of the connector industry, and it is expected to occupy a larger proportion in the future driven by automotive electronic products. In terms of product cost structure, the average cost of connectors used in each car in China is only a few hundred yuan, and the cost of connectors per car in foreign countries is about $125 to $150. great development potential. There will be 600-1,000 electrical connectors per car in the future, far greater than the number used today.

       China is expected to become an important production base for global automotive connectors in the future. In addition to the existing first-line well-known international manufacturers, other manufacturers that have not yet set up factories in China will gradually establish production bases in China to supply local auto parts manufacturers due to factors such as increasing local demand, localized procurement, and cost advantages. need.

       Therefore, in the future, China's automotive connector industry will be a very competitive market between foreign companies and Chinese local companies! With the development of foreign-funded enterprises and local enterprises, China will also become one of the important producers of automobile connectors. We will wait and see who will become the overlord of China's automotive connectors in the future of local enterprises, foreign-funded enterprises and foreign-funded enterprises!

      To sum up, I believe that everyone has a preliminary understanding of automotive connectors and corresponding reference value. I hope it will be helpful to everyone. If you have any needs and help, please feel free to contact us.
