There are two main functions of car wiring harnesses throughout the vehicle. One is to connect the power supply of the car to various electrical components, and the other is to relay information between the various electrical components of the vehicle. As people's requirements for comfort, economy, and safety continue to increase, the number of electronic products in cars is also increasing, and the design process of automotive wiring harnesses is also becoming more complicated. The colleagues who are engaged in the design of automotive wiring harnesses should be aware that there are many details to be paid attention to in harness design, such as the drawing of the previous vehicle schematic, the determination of the direction of the wiring harness and protection, the selection of conductors, the selection of terminals and sheaths, and the protection of fuses. Choices, etc., require the harness designer to be careful and careful.
There are several details that should be noted in the design of automotive wiring harnesses.
First, the layout of the wiring harness in the car as far away from the heat source, to be waterproof, anti-corrosion, to avoid friction; in the vulnerable line of the collision, the use of soft protection;
Second, harness design is safe, reliable, and repairable, and does not cause heat build-up.
Third, the electrical performance is better, so the direction of the harness is as short as possible to reduce the line voltage drop. As long as the mechanical strength is satisfied, finer wires can be used to reduce the weight of the wire harness;
Fourth, try to adopt a modular design, such as: a subsystem as much as possible to design a wire harness;
Fifth, the productivity is better, such as: add waterproof glue, set the hose to be easy. The more complex the wire harness, the more likely the frequency of failures is. This requires the wire harness designer to study in a multi-faceted manner, carefully and carefully, to ensure the reliability and durability of the wire harness.
