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
The invention belongs to the electromagnetic protection field of prevention electromagnetic information leakage and electromagnetic pulse interference, particularly a kind of flexible daylighting 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 daylighting electromagnetic shielding window that is not suitable for tent.Existing electromagnetic shielding window is different according to 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 fixed shield, disposable being in place, and no matter be wire netting or wire netting additional transparent glass, they all do not satisfy the base attribute that tent frequently set up, removed receipts, folds, packs.The flexible daylighting electromagnetic shielding window that research meets the tent attribute and possesses high screening effectiveness is one of electromagnetic shielding tent bottleneck technology of waiting to break through.
Summary of the invention
The objective of the invention is to study a kind of flexible daylighting electromagnetic shielding window that has the tent attribute and possess high screening effectiveness, thoroughly change the present situation that relies on power lighting in the electromagnetic shielding tent day and night fully, fundamentally solve the visual environment in the 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, the flexible metal shielding cloth cloth frame that superposes around wire netting, 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, wire netting and outside air are isolated, stop wire netting oxidation, corrosion, cause changes in material properties, the problem of forfeiture shielding properties.Metallic shield cloth cloth frame material is identical with tent shielding paulin shielding cloth material, and forms stitch together with the shielding paulin by the metallic shield cloth cloth frame of periphery.The screening effectiveness of forms is not less than the screening effectiveness of paulin body, and forms and paulin body are integrated, establish after need not, collapsible, 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, the flexible metal shielding cloth cloth frame 1 that around wire netting 3, 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 on wire netting 3 surfaces, electroplate the back metallic shield cloth cloth frame 1 that superposes around wire netting 3, 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 is through the HTHP stickup shaping.When being applied on the tent, forms are placed 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 incorporated into together.
The flexible daylighting electromagnetic shielding of the present invention window, because wire netting has been carried out 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 by original mutual overlap joint through the broadwise interface point and to be welded to each other, mesh is fixed, not yielding, further improve the conductive magneto-conductive of wire netting simultaneously by electrodeposited coating, thereby the screening effectiveness of wire netting is further improved on original basis, and particularly low frequency performance significantly improves.Around net is double-edged, sew up the approaching flexible electromagnetic shielding cloth of screening effectiveness and net and form cloth matter window frame, cloth forms the continuous conduction body with net, again the net two sides applying 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 the 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 daylighting electromagnetic shielding window is bandwidth, screening effectiveness height not only, and pliability is good, has the attribute of tent, and forms and tent form one, and be succinct, reliable, practical.
