Cars are the most familiar means of transportation in our daily life. With the development of China's social economy and the general improvement of people's living standards, cars have become the most affordable means of transportation in most homes. Cars with high comfort, faster speed and high safety have become an indispensable travel tool in daily life. Therefore, the car sales market is particularly large and the development trend is very rapid. In this year's edition, we're going to explore the basics of connectors in automotive wiring harnesses. Many people know that there are hundreds of automotive optical connectors. Do you know the types of car connectors?
In general, the types of automotive connectors can be screened from six aspects: electrical equipment function, installation method, snap structure, appearance specifications, specifications, appearance specifications, and output power. The details are as follows:
1. According to the function of electrical equipment: electronic device controller (trip computer), socket, temperature sensor, intermediate electrical box, central air-conditioning electronic wiring harness, speaker game entertainment
2. According to the assembly position: car brake system, in-vehicle dashboard, engine system, protection system
3. According to the buckle structure: line single pick, line to board, board to board, flexible circuit board FPC, integrated circuit chip (IC pin type)
4. According to size specifications: square, ring
5. According to appearance specifications: circular connectors (general, coaxial), square connectors (sealed, non-sealed)
6. By output power: low frequency and high frequency (with 3 as 3 MHz demarcation)
For other main purposes, special structures, installation steps, unique characteristics, etc., the types of automotive connectors can also be divided into different types, but generally only to highlight a certain feature and main purpose, basically the classification still shall not exceed The above classification principles.
Fully considering the professional technology development and specific situation of automotive connectors, the article discusses other categories of automotive connectors: ① low frequency circular connectors; ② square connectors; ③ printed circuit board connectors; ④ optical fiber cable connectors; ⑤ RF connector.
There are some technical terms that you must be familiar with, although you do not drive, you must also see them in the exam of subject one, such as car braking system, car dashboard, engine system, temperature sensor, etc. This critical function is inseparable from the credit of automotive electronic device connectors. The above are the types of automotive connectors to be introduced today. I believe that through the detailed introduction, I have a deeper grasp of the basics of automotive connector types.
In recent years, with the general improvement of national living standards, the car is no longer a "luxury brand" that the rich cannot afford, it has entered thousands of homes. People have higher and higher requirements for the safety, comfort, environmental protection and intelligence of cars, and more and more automotive electronic devices, such as car speakers, GPS navigation, entertainment items, car airbags, in-vehicle fiber optic cables, Internet, ABS system, etc. With the complexity of the internal structure of automobiles, more and more automobile connectors are required. It is expected that the number of automotive electronic device connectors will reach 600 to 1000 per vehicle in the future, and the types of automotive connectors may also change. In the future, the automotive connector sales market will be particularly large, and the development prospects are also very exciting.
