Shielding interference source equipment and related wiring harness: Motorcycle wire harness wholesalers introduces 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.
In addition, the electromagnetic interference of the automobile system is also caused by electromagnetic interference from the outside of the vehicle and the vehicle body. The interference outside the vehicle is the interference experienced when the vehicle is subjected to various external electromagnetic environments, and the static interference of the vehicle body is related to the automobile and the external environment. . These two kinds of electromagnetic interference also occur in daily car operation, which deserves attention. If you want to learn more about transmission wire harness made in China,you can contact us.
