Flexible lighting electromagnetic shielding window
Technical field
The invention belongs to the electromagnetic protection field of prevention electromagnetic information leakage and electromagnetic pulse interference, particularly a kind of flexible lighting electromagnetic shielding window of electromagnetic shielding tent.
Background technology
The electromagnetic shielding tent of the above high screening effectiveness of 60dB is not all established light inlet window both at home and abroad at present, and reason is the high screening effectiveness lighting electromagnetic shielding window that is not suitable for tent.Existing electromagnetic shielding window is according to the difference of shielding frequency range and screening effectiveness, the main wire netting that adopts homogenous material, or at the two sides of wire netting additional transparent glass, the wire netting of homogenous material is mainly used in low-frequency range and the less demanding occasion of screening effectiveness, wire netting additional transparent glass is mainly used in the fixed shielding body, disposable being in place, and no matter be wire netting or wire netting additional transparent glass, they all do not meet the base attribute that tent frequently set up, removed receipts, folds, packs.The flexible lighting electromagnetic shielding window that research meets the tent attribute and possesses high screening effectiveness is that electromagnetic shielding tent waits one of Pinch technology of breaking through.
Summary of the invention
The object of the invention is to study a kind of flexible lighting electromagnetic shielding window that has the tent attribute and possess high screening effectiveness, thoroughly change in electromagnetic shielding tent and rely on day and night the present situation of power lighting fully, fundamentally solve the visual environment in electromagnetic shielding tent, reduce visual fatigue, improve personnel's operating efficiency.
Technical scheme of the present invention is achieved in that and the present invention includes a flexible metal net, at the surrounding of the wire netting flexible metal shielding cloth cloth frame that superposes, the two sides composite and flexible transparent film of wire netting.
Described wire netting is of a size of 640mm * 540mm, and metallic shield cloth cloth frame outside dimension is that 700mm * 600mm, inside dimension are 600mm * 500mm, and transparent film is of a size of 650mm * 550mm.
The present invention adopts said structure, and metallic shield cloth cloth frame and wire netting form the continuous conduction body, and transparent film seals wire netting fully, make wire netting and outside air isolation, stop wire netting oxidation, corrosion, cause changes in material properties, lose the problem of shielding properties.Metallic shield cloth cloth frame material is identical with tent shielding paulin shielding cloth material, and forms stitch together by peripheral metallic shield cloth cloth frame and shielding paulin.The screening effectiveness of forms is not less than the screening effectiveness of paulin body, and forms and paulin body are integrated, without after establish, collapsible, the packing.

Below in conjunction with accompanying drawing, content of the present invention is described in further detail.
Embodiment
Shown in seeing figures.1.and.2, the present invention includes a flexible metal net 3, at the surrounding of the wire netting 3 flexible metal shielding cloth cloth frame 1 that superposes, the two sides composite and flexible transparent film 2 of wire netting 3.
During processing and fabricating, by size cutting wire netting 3, metallic shield cloth cloth frame 1, transparent film 2.Electroplating processes is carried out in wire netting 3 surfaces, after plating, at the surrounding of wire netting 3 stack metallic shield cloth cloth frame 1, use with the shielding sewing thread two pass of the metallic shield cloth same sex and sew up, the compound film 2 on the two sides of wire netting 3 afterwards, through the HTHP stickup shaping.While being applied on tent, forms are placed in to tent the window's position, the shielding tarpaulin side seam corresponding with shielding paulin window periphery by the metallic shield cloth cloth frame of forms periphery is combined together.
Flexible lighting electromagnetic shielding window of the present invention, due to wire netting has been carried out to special electroplating processes, its appearance characteristics and physical characteristic are significantly changed, electroplate liquid contains high conduction and magnetic conduction composition, by electroplating processes, wire netting is become and is welded to each other by original mutual overlap joint through the broadwise interface point, mesh is fixed, not yielding, further improve the conductive magnetic properties of wire netting by electrodeposited coating simultaneously, thereby the screening effectiveness of wire netting is further improved on original basis, and particularly low frequency performance significantly improves.Sew up the screening effectiveness flexible electromagnetic shielding cloth formation cloth matter window frame approaching with net in the double-edged surrounding of net, cloth forms the continuous conduction body with net, again at the two sides of net laminating toughness film, under special process, the film on net two sides is bonded together by mesh, and wire netting is sealed in the middle of film, and net is isolated from the outside, especially electrodeposited coating does not does not wear and tear, not oxidation, does not break away from, thus its screening effectiveness is remained high, stablize constant.This flexible lighting electromagnetic shielding window not only bandwidth, screening effectiveness is high, and pliability is good, has the attribute of tent, and forms and tent form one, succinct, reliable, practical.
