How to shield automotive wiring harnesses from electromagnetic interference

Automotive electronic equipment working in the traveling environment is constantly changing on the car, the complexity and variability of the electromagnetic energy composition of the environment, means that the system is subjected to a wide range of sources of electromagnetic interference. Automotive wiring harnesses throughout the car, is the main source of electromagnetic interference within the car, and its own from time to time by electromagnetic interference. So how the automotive harness to deal with electromagnetic interference is particularly important. 1. shielding interference source equipment and related wiring harness: the main electronic control system in the car using the electronic control unit, should be shielded shell package. 2. increase the harness filtering: the longer the harness, in order to reduce the conductive and radiated interference should be added to the harness filtering, it is more convenient is to set up the appropriate ferrite ring. 3. reasonable planning harness: harness layout On the small power sensitive circuits close to the signal source, high-power interference circuits close to the load, as far as possible to separate the small power circuits and high-power circuits, reduce the harness between the induction and radiation interference. 4. improve the grounding of the equipment: a good grounding arrangement and improve the ground lap can reduce the high-frequency impedance. Automotive electronic equipment grounding is mainly close to the car body as well as the harness shielding layer grounding. 5. Reduce the area of the wiring harness to receive interference: the wiring harness should be designed to minimize the length, minimum impedance and minimum loop area, and better use of twisted-pair wires and other power supply with a small loop area. Increase the distance from the equipment to the source of interference: In the case of unchanged arrangement of interference equipment, remodel the installation position of sensitive components to increase the distance to the source of interference.-6, on the BBC Electronic Products Network platform related to the introduction and sales of products brief: BBC Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand what connectors | harness | wire and cable product solutions that we can provide, please contact our Division below!
