Flexible lighting electromagnetic shielding window

Abstract

The invention discloses a flexible lighting electromagnetic shielding window. The window comprises a flexible metal net, wherein a flexible metal shielding cloth frame is superposed around the metal net; and flexible transparent films are combined on the two surfaces of the metal net. The window has the following beneficial effects: based on the structure provided by the invention, the metal shielding cloth frame and the metal net form a continuous conductor and the transparent films fully seal the metal net to isolate the metal net from the outside air, thus putting an end to the problems of material performance variation and shielding performance loss due to oxidation and corrosion of the metal net; the metal shielding cloth frame and the shielding tent cloth are made of the same material; the window body and the shielding tent are sutured together via the peripheral metal shielding cloth frame; the shielding effectiveness of the window body is not lower than that of the tent body; and the window body is integrated with the tent body, is unnecessary to be arranged later and can be folded and packaged.

Description

technical field [0001] The invention belongs to the field of electromagnetic protection for preventing electromagnetic information leakage and electromagnetic pulse interference, and in particular relates to a flexible daylighting electromagnetic shielding window for an electromagnetic shielding tent. Background technique [0002] At present, the electromagnetic shielding tents with high shielding effectiveness of more than 60dB at home and abroad do not have daylighting windows, because there is no high shielding efficiency daylighting electromagnetic shielding windows suitable for tents. According to different shielding frequency bands and shielding effectiveness, the existing electromagnetic shielding windows mainly use metal mesh of a single material, or add transparent glass on both sides of the metal mesh. The metal mesh of a single material is mainly used in low-frequency bands and occasions where the shielding efficiency is not high. , The metal mesh with transparent...

According to different shielding frequency bands and shielding effectiveness, the existing electromagnetic shielding windows mainly use metal mesh of a single material, or add transparent glass on both sides of the metal mesh. The metal mesh of a single material is mainly used in low-frequency bands and occasions where the shielding efficiency is not high. , The metal mesh with transparent glass is mainly used for fixed shielding body, which can be installed in place at one time, and whether it is metal mesh or metal mesh with transparent glass, they do not meet the basic properties of frequent erection, withdrawal, folding and packaging of tents
