Shielding of wiring harness refers to reducing the impact of electromagnetic interference (EMI) on signals inside the harness through physical and electrical means, while preventing interference from signals inside the harness to the outside world. The following is a detailed description of the definition, application, and functions of wire harness shielding

：

definition

Wire harness shielding refers to wrapping a layer of conductor material (such as braided copper mesh or aluminum foil) around the outside of a conductor, which is called a shielding layer. The shielding layer usually needs to be grounded in order to introduce external interference signals into the ground

.

application

Wire harness shielding is widely used in various electrical and electronic devices, especially in scenarios that require high electromagnetic compatibility (EMC). For example:

Automotive Electronics: In new energy vehicles, high-voltage wiring harnesses require shielding layers to prevent electromagnetic interference from affecting the vehicle's control system

.

Industrial automation: In industrial environments, wire harness shielding can prevent mutual interference between devices and ensure the stability of the production process

.

Medical equipment: Shielding the wiring harness in medical equipment can prevent electromagnetic interference from affecting the accuracy and reliability of the equipment

.

function

Electromagnetic shielding: The shielding layer can reduce or prevent the impact of electromagnetic interference, providing electromagnetic compatibility (EMC) protection

.

Electromagnetic tolerance: The shielding layer can help the wiring harness resist external electromagnetic radiation or radioactive interference, ensuring the normal operation of the system

.

Reduce electromagnetic radiation: The shielding layer can reduce the electromagnetic radiation generated by the wiring harness and improve safety

.

Protection of wiring harness: The shielding layer can act as a protective layer to prevent the wiring harness from being affected by mechanical damage, chemical corrosion, or other adverse factors

.

Voltage isolation: In some cases, the shielding layer can provide voltage isolation function, ensuring electrical isolation between different parts

.

Insulation enhancement: The shielding layer usually has certain insulation properties to enhance the overall insulation performance of the wire harness
