Well, let's talk to you:Automotive wiring harnessHow is it arranged, you know?

Harness is the nervous system of vehicle electrical appliances, which plays a vital role in the realization of vehicle electrical functions. The electrical safety of the whole vehicle has always been the most concerned problem of various automobile manufacturers. The working environment of each area may have an impact on the harness. Waterproof is an important content in the harness design. Therefore, this paper will briefly analyze the waterproof design of the harness.

 1. Distribution of dry and wet areas of the whole vehicle

The vehicle wading depth refers to the deepest water area that the vehicle can pass through, which is also a safe depth. The area below the wading line and the engine compartment is called the wet area. On the contrary, the area where the wire harness installed in the cab, passenger compartment and luggage compartment does not need special waterproof protection treatment is called the dry area. In order to improve the wading trafficability and safety of the whole vehicle, the wading depth of the whole vehicle shall be fully considered in the electrical system design, and the key electrical parts of the whole vehicle shall be arranged in the dry area.

2. Harness layout

According to the distribution of dry and wet areas of the whole vehicle, we divide the whole vehicle harness into the following parts: front compartment harness, powertrain harness, instrument harness, indoor harness, ceiling harness, four door harness and back door harness. According to the distribution of dry and wet areas of the whole vehicle, the front compartment harness, powertrain harness and four door harness are located in the wet area. This part of the money harness shall be waterproof and protected, and the part connected with the indoor shall be sealed with rubber parts. Other wire harnesses are located in the dry area, and the connector does not need to be waterproof. However, in order to prevent water from entering the room when connecting with the outside, corresponding waterproof treatment should also be done.
