The purpose of the automobile
Wiring Harness is to select a suitable model scheme from several styling schemes so as to serve as the basis for technical design. The main wiring harness of the automobile wiring harness is often centered on the dashboard and extends forward and backward. Due to length or assembly convenience, the wiring harness of some automobiles is divided into the front wiring harness, the rear wiring harness, the roof wiring harness, etc. The wiring harness of new energy vehicles will be marked with numbers and letters at each end to indicate the connection object of the wire. The operator can see the mark and correctly connect to the corresponding wires and electrical devices, which is particularly useful when repairing or replacing the wiring harness. It is generally determined by two needs. One is that the ambient temperature of the wire and cable is high, and the cable can normally transmit signals or electrical energy at high temperatures for a long time; the other is the power transmission vehicle wiring harness, which is mainly for the purpose of increasing the interception capacity.
The load-increasing high-temperature automobile wiring harness, according to the size and basic shape of the car determined by the general layout design, can outline the specific image of the car. The main wiring harness is often centered on the dashboard and extends forward and backward. Due to the length relationship or the convenience of assembly, some automobile wiring harnesses are divided into front wiring harnesses, rear wiring harnesses, and roof wiring harnesses. The main purpose is to reduce the outer diameter and weight of the cable under the premise of ensuring current carrying, and to develop towards lightweight. Generally speaking, the higher the working temperature of the vehicle wiring harness, the greater the current carrying capacity of the cable with the same cross-section. In occasions such as airplanes and automobiles, weight reduction is of great significance, and high temperature is used to greatly reduce the cross-section. When the working temperature rises from 90℃ to 155℃, the current carrying capacity increases. Under the same current carrying capacity, the weight of the cable should be reduced by half, and the cost is also reduced. Of course, at the same time as the high current cutoff, the power loss of most insulating materials will also increase. Automobile wiring harness working in high temperature environment. Ordinary vehicle wiring harnesses are prone to insulation aging and scorching at high temperatures, and the used cables lose their performance and are damaged and cannot be used. High-temperature cables can work normally and stably at rated high temperatures, and the signal or power transmission performance is not affected, and the cable can also be guaranteed to have a long service life. This type of functional cable is one of the most common high-temperature vehicle wiring harnesses, and its usage characteristics are also easy to understand.
