Selection of wire harness fasteners
In the design process of the wire harness fixing structure and related functional boxes, the commonly used standard parts are used as much as possible, and the types of standard parts are as few as possible, and the use of special tools in assembly and maintenance is reduced through early design.
● Influence on the installation of surrounding parts
In the design process, the characteristics of different areas are considered in a targeted manner, and the direction of the designed wiring harness must not affect the assembly of other vehicle parts;
● Electromagnetic compatibility and anti-electromagnetic interference
Regarding electromagnetic compatibility and anti-electromagnetic interference, it should not only be done from the selection of wire materials, such as the use of twisted pairs, shielded wires, etc., but also from the wiring direction of the wire harness.
Some models with a rear luggage compartment with a battery have a large diameter wire running through the whole car because the current needs to be transmitted to the electrical box in the engine compartment and the starter, and a strong current is always passed through. In traditional wiring, placing this high-current wire in the same harness without distinguishing it from other signal wires is bound to cause interference to the signal wire. Therefore, the high-current wire is usually arranged in a separate direction, leaving enough space with the ordinary wire harness. Long distance (above 100mm), at the same time, it is required to make a groove in the sheet metal for laying the wire, and it can have a certain electromagnetic shielding effect.
