Motorcycle wire harness wholesalers introduces automotive electronic equipment works in cars with changing driving conditions. The complexity and variability of electromagnetic energy in the environment means that the system is exposed to a wide range of electromagnetic interference sources. Automobile wiring harnesses are scattered throughout the vehicle and are the main source of electromagnetic interference inside the car, and they are often subjected to electromagnetic interference. Therefore, how to deal with electromagnetic interference is especially important for automotive wiring harnesses.

Shielding interference source equipment and related wiring harness: The electronic control unit used in the main electronic control system of the automobile should be packaged in a shielded housing.

Adding harness filtering: For longer harnesses, to reduce conduction and radiation interference, filter should be added to the harness. It is convenient to sleeve the appropriate ferrite ring.

Reasonable planning of the wiring harness: The wiring harness arrangement makes the small power sensitive circuit close to the signal source, the high power interference circuit is close to the load, and the small power circuit and the high power circuit are separated as much as possible to reduce the inductive interference and radiation interference between the wire harnesses.

Improve grounding of equipment: Good grounding and improved grounding can reduce high frequency impedance. The grounding of automotive electronic equipment is mainly connected to the vehicle body and the wiring layer of the wiring harness.

Reduce the area of wire harness receiving interference: The wire harness should be designed to have the minimum length, minimum impedance and minimum loop area. It is best to use a power supply with a small loop area such as twisted pair. Increase the distance from the device to the interference source: In the case of the same arrangement of the interference device, modify the installation position of the sensitive component and increase the distance to the interference source.
