There are nearly a hundred types of connectors used in general automobiles, and hundreds of connectors are used in a single vehicle. As people have higher and higher requirements for automobiles in terms of safety, environmental protection, comfort, and intelligence, the application of automotive electronics is increasing, which will increase the number of automotive connector applications.
Automotive connectors are a component often used by electrical engineering technicians. Its function is very simple. It can build a communication bridge between the blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. The form and structure of automotive connectors are ever-changing, and are mainly composed of four basic structural components.
Four basic structural components of automotive connectors.
1. Contacts. It is the core part of the automotive connector to complete the electrical connection function. The contact pair is generally composed of a positive contact and a negative contact, and the electrical connection is completed by the mating of the female and male contacts.
2.Shell. It is the cover of the car connector, it provides mechanical protection for the built-in insulation mounting plate and pins, and provides the alignment of the plug and socket when mating, thereby fixing the connector to the device.
3. Insulators. Insulators are often referred to as automobile connector bases or inserts. Its role is to arrange the contacts at the required position and spacing, and to ensure that the contacts and contacts Insulation performance with the shell. Good insulation resistance, voltage resistance performance and easy processability are the basic requirements for selecting insulating materials for processing into insulators.
4. Accessories. The accessories are divided into structural accessories and installation accessories. Structural accessories such as collars, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, seals, gaskets, etc. Installation accessories such as screws, nuts, screws, spring coils, etc. Most of the accessories have standard parts and universal parts.
It is these four basic structural components that enable the automotive connector to act as a bridge for stable operation.
At present, the global automotive connector industry accounts for about 15% of the connector industry. It is expected that in the future, driven by automotive electronics products, it will occupy a larger proportion. China's automotive connector market still has great development potential. In the future, 600-1,000 electronic connectors will be used per car, which is much larger 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 who have not yet set up factories in China will gradually build up production bases in China to supply local auto component manufacturers because of the growing local demand.
In the future, China's automotive connector industry will be a very fierce market for foreign companies and local Chinese companies! With the development of foreign-funded enterprises and local enterprises, China will also become one of the important producers of automotive connectors.
