AI Technical Summary

Technical Problem

Existing control system housing structures cannot achieve high-efficiency electromagnetic shielding performance while ensuring housing manufacturability. Conductive plastics have high volume resistivity, making it difficult to meet the shielding requirements for high-frequency electromagnetic interference. Conductive fiber layer solutions are only suitable for thin sheet metal parts and are difficult to adapt to complex-shaped housings.

Method used

An electromagnetic shielding device is formed by combining a metal conductive component as the inner liner and the shell to create an integrated structure. The inner liner and the cover plate are electrically connected through connectors, which reduces electrical clearance, enhances the electromagnetic shielding effect, and adapts to complex shell designs.

Benefits of technology

It improves electromagnetic shielding capability, meets high-frequency signal shielding requirements, adapts to various complex shell designs, simplifies processing technology, and enhances electromagnetic shielding effectiveness.
