At present, the global automotive connector market accounts for more than 15% of the connector market, and its proportion will be even greater under the drive of automotive electronics in the future. As people have higher and higher requirements for safety, environmental protection, comfort, intelligence, etc., the application of automotive electronic products is increasing, which will cause the number of automotive. In addition, cars have also become necessities in people’s daily life, and a car needs hundreds of car connectors. It can be seen that automobile connectors play an important role in cars, so it is necessary for us to understand some basic knowledge of car connectors. Such as how to wire the automobile connectors, this article will give a brief introduction
The composition of the automobile connectors

The future development trend of automotive connectors
(1)The composition of the automobile connectors
1.The Contacts
The contact piece is the core component of the automobile connector, and its main component is the male contact piece and the female contact piece, and the electrical connection is completed by the insertion of the two.
2.the shell
The shell is also an outer cover, which provides mechanical protection for the built-in insulating mounting plate and pins, and provides alignment of the plug and socket when mating, and then fixes the connector to the device.
3.Insulator
The main function of the insulator is to allow the contacts to be arranged as required and to ensure insulation between the A contact and the B contact. The material of the insulator requires good insulation resistance, withstand voltage performance and easy processing.
4.Accessories
The accessories are divided into structural accessories and installation accessories.

Board connection technology Press-in: low cost and high efficiency. The definition of a press-in connector is that a pin (also called a terminal) is pressed into a hole smaller than its outer diameter by an external force. This press-fit connection method is called press-fit, also called crimping. Because it has low cost, high efficiency, simple operation and high reliability compared with SMT (Surface Mount Technology, which is a kind of connection technology)The industry has designed various shapes for Press-fit terminals, each of which has advantages and disadvantages. Among them, the fish-eye hole terminal is the most widely used Press-fit terminal structure. For complex crimping, upper and lower crimping dies are indispensable.
Wiring technology Crimp: higher quality wiring
Crimp is a cold-pressing technology, and its origin can be traced back to around 1940. The principle is to use crimping tools or crimping tools to complete the crimping of metal wires and pins. This kind of crimping has good air tightness, corrosion resistance, and wire deformation must exceed its yield point, so reliable data, signal and power transmission can be realized. During the crimping process, the oxide layer or the vulcanized layer of the wire can be removed, and the residual elasticity of the crimping needle and the wire can ensure a lasting electrical connection. This method is suitable for the use of Category 2, Category 5 and Category 6 wires with wire diameters ranging from 0.08mm² to 240mm². There is evidence that solid wires can also be crimped, but the quality of crimping needs to be tested and confirmed
(3) The future development trend of automotive connectors
It can be said that the "miniaturization", "high-speed mobility" and intelligence of automotive connector products are the future development trends. The future development trends of the connector industry are as follows.
The first point is the miniaturization technology of connectors. This technology is mainly developed for the trend of connector miniaturization and can be applied to micro-miniature connectors below 0.3mm.
The second point is the high-frequency and high-speed wireless transmission connector technology.
The third point is intelligent connector technology.
The fourth point is precision connector technology.
