Cars are the most common means of transportation in our daily lives. With the development of our country's economy and the general improvement of people's living standards, cars have become an affordable means of transportation for most families. The comfort, speed and safety of automobiles have become an indispensable means of transportation in modern life. Therefore, the automobile market is huge and developing very rapidly. This year, we discussed the relevant knowledge of connectors in automotive wiring harnesses. Many people know that there are hundreds of optical connectors in a car. So do you know how to distinguish the types of automotive connectors? The following introduces you to the specific classification of automobile connectors. Generally speaking, the types of automotive connectors can be divided into six aspects: function, installation position, connection structure, shape specifications, size specifications, shape specifications, and operating frequency.





1. Electrical functions: electronic control module (on-board computer), lamp holder, temperature sensor, central electrical box, air conditioning wiring harness, audio entertainment

2. Classified by installation location: chassis system, instrument system, engine system, safety system

3. According to the connection structure of line-line-board-board, flexible circuit board FPC, chip package (IC pin type)

4. Dimensions: rectangular, round

5.According to shape specifications: round tube (ordinary, coaxial), rectangular tube (sealed, non-sealed)






6. Classification by operating frequency: low frequency and high frequency (limited to 3 MHz). For other classification methods, automotive connectors can still be classified according to use, special structure, installation method, special performance, etc., but generally just to highlight certain Characteristics and uses, the basic classification still does not exceed the above classification principles.

Combined with the technological development and actual situation of automotive connectors, let me introduce to you other categories of automotive connectors: ① low-frequency circular connectors; ② rectangular connectors; ③ printed circuit connectors; ④ optical fiber connectors; ⑤ radio frequency connections device. There are some terms that sound familiar to you, but you have rarely seen them, such as chassis system, instrument panel, engine system, temperature sensor, etc. The realization of these important functions is incomparable to automotive electronic connectors. The above are the types of automotive connectors that I will introduce to you today. Through the above explanation, do you have a clear understanding of the types of automotive connectors?

With the general improvement of people's living standards, cars are no longer a "luxury" that wealthy people can afford, and they have entered thousands of households. The demand for automobiles in terms of safety, comfort, environmental protection, and intelligence is growing day by day. The applications of automobile electronic products such as car audio, GPS navigation, entertainment equipment, airbags, automobile optical fiber networks, ABS systems, etc. are also increasing. As car interiors become more complex, more car connectors are needed. It is expected that the number of automotive electronic connectors will reach 600 to 1,000 per vehicle in the future, and the types of automotive connectors may also change. The automotive connector market will become larger and larger in the future, and its development prospects are also worth looking forward to.
