Nine Design Requirements For Automotive Connectors

Nine Design Requirements For Automotive Connectors

Automotive Connectors Suppliers will share this article with you about the design requirements for automotive connectors.

1. Stable and reliable connector contact material;

2. The stable positive force;

3. The voltage and current of the connector connection circuit are stable;

4. The temperature requirements are within the specified range, including the surrounding temperature and its own temperature rise;

5. Better robustness. Automobile connectors must be able to work reliably under harsh conditions;

6. It must be the same as the connector used for high-speed and long-distance communication computers;

7. Connector insertion force: 20.5kg or less;

8. Connector retention: 2.5kg or more;

9. Temperature adaptability: -40~120℃.

In the driving of the car, the various parts of the car must work, and the various parts must be closely coordinated. In the coordination of various parts of the car, the car connector plays a very important role. Whether it is a traditional car or a new energy car, in the automotive industry, connectors have always been valued by engineers. In the analysis of some traffic accidents, people found that many traffic accidents are caused by connector failure.

From the purpose of the use of automobile connectors, in order to ensure that the car can run better, we can divide the reliability of the connector into the sealing performance of the connector in use, the performance of the car is driving, and the performance of the car. During driving, the connector can also show shielding performance and temperature control performance.

Generally speaking, when discussing the sealing performance of automobile connectors, it is not only for the sealing performance of water in the automobile. In this field, the internationally popular management standard is IP67, and this standard is also the highest level in the automotive closed industry. Although the requirements for waterproofing are different in different parts of the car, many car manufacturers will choose IP67 to ensure the airtight performance of their car's connectors.

In the driving of a car, the power source is a very important source of energy, which is not only related to the normal operation of the engine but also often involves the use of power when people are driving. Therefore, in the power system of the car, the car connector has different divisions, between the male connector and the device, between the male connector and the cable, between the male and female connectors, and the female connector. There are certain sealing measures between the end connector and the cable that can be implemented.

In realizing the sealing performance of automobile connectors, the sealing ring is a commonly used tool. This tool can not only realize the fixing effect between different holes but also realize the sealing effect. It can not only ensure the stable operation of automobile equipment but also ensure the waterproof performance of automobile equipment during work. Silicone rubber is used for most of the sealing ring. This material is made of liquid silicone and solid silicon after a certain chemical change.

Now in the use of cars, electronic circuit technology is an important aspect of the automotive industry, not only in the entertainment of the driver but also in the control system of the car while the driver is driving. Electronic circuit technology plays an important aspect in the stable operation of the car.

In order to ensure that the electronic circuit technology can work stably, many shielding technologies are now applied in the production of automobiles. These shielding technologies not only play a protective role in automobile electronic circuits but also have anti-interference and anti-radiation capabilities in automobile components. In addition, they can also protect the stable operation of automobile connectors. These shielding technologies in automobiles can be divided into two types: inner shielding and outer shielding.

When using external shielding to protect automobile connectors, two identical shielding shells are usually assembled together to form a shielding layer, and the length of the shielding layer can cover the length of the entire connector. There are enough lock plate structures to ensure the reliable installation of the shielding layer. In addition, the shielding material used must not only be electroplated but also be treated to prevent chemical corrosion.
