Abstract

The invention discloses an electromagnetic shielding structure of a lighting window of a lightweight square cabin and relates to the technical field of square cabins. The electromagnetic shielding structure of the lighting window of the lightweight square cabin comprises an outer sealed window and an inner sealed window; the outer sealed window comprises an outer window frame, toughened glass, a water sealing rubber strip and a wire mesh layer; the wire mesh layer is electrically communicated with the outer skin of a wallboard through the outer window frame; the inner sealed window comprises a copper plate frame, a pressing plate frame, a shock-reducing rubber strip and shielding glass; a nickel-plated mesh is electrically communicated with the inner skin of the wallboard through the copper plate frame, and therefore a two-layer telescopic Faraday electromagnetic cage. The electromagnetic shielding structure disclosed by the invention especially aims at the lightweight square cabin that an aluminum alloy plate of 0.5-1mm is adopted by the inner skin and the outer skin, is capable of performing electric communicating on the inner skin and the outer skin, can fully meets the shielding requirement of being greater than 40db within a frequency band range of 100KHz-10GHz in the military standard requirement, and is capable of ensuring water tightness, gas tightness, heat retaining property and light transmission of the cabin body at the lighting window.

Description

[0001] technical field [0002] The invention relates to the technical field of shelters, in particular to an electromagnetic shielding structure of light-weight shelter lighting windows. Background technique [0003] Generally, the wall panels of the shelter are made of aluminum alloy plates of about 1.5mm as the inner and outer skins, and polyurethane foam cores are sandwiched between the inner and outer skins as insulation materials. The shielding of the cabin is mainly realized by the conduction of the inner skin , the daylighting windows used on the cabin are also mainly electrically connected by the nickel-plated wire mesh in the inner shielding glass and the inner Mongolian aluminum plate. The inner and outer skins of lightweight shelters are generally made of 0.5-1mm aluminum alloy plates, and it is difficult to achieve the shielding greater than 40db in the 100KHz-10GHz frequency range required by the national military standard for wall panels and daylighting window...
