Application of high voltage wire harness for waterproof automobile

With the continuous development of science and technology, the automobile industry is also constantly improving. In modern society, vehicles have become an indispensable part of People's Daily life. In order to ensure driving safety, the high-voltage wiring harness system of on-board electronic equipment has gradually become an important part. However, due to the particularity of high voltage wiring harness system, its waterproof performance has become one of the key problems. This paper will introduce the application and importance of high voltage wire harness for waterproof automobile.

First of all, the importance of waterproof automotive high-voltage wiring harness is self-evident. High-voltage wiring harness is a very important part of the vehicle electrical system, which is responsible for transmitting electrical energy and control signals. If the high-voltage wiring harness fails or is damaged, it will cause the entire vehicle electrical system and control unit to fail to work normally, seriously threatening the driver's driving safety. Therefore, the requirements for waterproof automotive high-voltage wiring harnesses are very high:

1. High temperature resistance: In a high temperature environment, the high pressure wiring harness needs to be able to withstand a certain temperature change without affecting its working state. This requires that the material of the high pressure wire harness has good thermal stability and can remain stable at high temperatures for a long time.

2. Corrosion resistance: High pressure wire harnesses are usually exposed to humid environments and are susceptible to corrosion by chemical substances such as water vapor and salt spray. This requires that the corrosion resistance should be considered in the selection of materials to ensure that the high-voltage wiring harness will not be corroded during long-term use.

3. High strength: High voltage wiring harness needs to carry a large amount of current and voltage, so the strength and toughness of the material must be considered in the design. At the same time, it is also necessary to consider the firmness of the wiring harness connection to prevent loosening and falling off.

4. Low resistivity: the wires and insulation layers in the high-voltage wiring harness need to have the characteristics of low resistivity to reduce the loss of electrical energy and heating.

5. Reliability and safety: waterproof automotive high voltage wiring harness needs to have high reliability and safety requirements. In the design and manufacturing process, it is necessary to test and verify in strict accordance with relevant standards to ensure the normal operation of high-voltage wiring harnesses in various harsh environments.

Secondly, the application of waterproof automotive high-voltage wiring harnesses is also very extensive. Here are some common examples:

1. Vehicle navigation system: The high-voltage wiring harness system of the vehicle navigation system is responsible for receiving satellite signals and transmitting them to the vehicle controller. Waterproof automotive high-voltage wiring harnesses can prevent rain, dust and other dirt from entering the interior of the wiring harnesses, thereby protecting the reliability and stability of navigation instruments.

2. ABS brake system: The high voltage harness system of ABS brake system is used to transmit brake pressure and signals. Waterproof automotive high-voltage wiring harnesses can help avoid moisture intrusion in the brake lines, thus ensuring the normal operation of the brake system.

3. HVAC (air conditioning) system: The HVAC system's high voltage harness system is mainly used to transmit the signal between the compressor and the condenser. Waterproof automotive high-voltage wiring harness can prevent water and gas from entering the interior of the wiring harness, thus ensuring the normal operation of the air conditioning system.

In short, the application range of waterproof automotive high voltage wiring harness is very wide and important. With the continuous development of automobile technology and people's attention to driving safety, the demand for high-voltage wiring harnesses for waterproof vehicles is also increasing. Therefore, in the design, production and testing process, attention should be paid to improving the waterproof performance to ensure the reliability and safety of the high-voltage wiring harness system.
