AI Technical Summary

Technical Problem

Existing shielding tubes are prone to aging or damage when exposed to the external environment for a long time, resulting in a reduction in shielding effectiveness.

Method used

It adopts a composite structure from the inside out, including an aluminum foil layer, a tin-plated copper braided mesh layer, a flexible sheath, and an outer protective layer. Each layer of material has different functional characteristics, which together provide aging resistance and electromagnetic shielding performance.

Benefits of technology

The multi-layer composite structure improves the aging resistance and resistance to external damage of the shielding tube, extends its service life, and forms a dual shielding mechanism of high-frequency reflection followed by full-band attenuation, thereby enhancing the electromagnetic shielding effect.
