Abstract
The utility model discloses a shielding and anti-information leakage device for a computer, comprising a wire mesh. The shielding and anti-information leakage device for the computer has the following key points: two layers of polycarbonate rubber sheets are respectively arranged at two sides of the wire mesh, and glass sheet layers are respectively adhered on the outer sides of the polycarbonate rubber sheets and combined into an integral structure by hot pressing. The shielding and anti-information leakage device for the computer is suitable for visual windows of electromagnetic shielding bodies such as a computer electromagnetic shielding machine room, a computer electromagnetic protecting machine table, a server electromagnetic protecting machine cabinet and the like, effectively inhibits information leakage and resists electromagnetic interference, precludes damage on a human body caused by electromagnetic waves, effectively inhibits the leakage of computer electromagnetic information and prevents the technical problem of external strong electromagnetic disturbance. The shielding and anti-information leakage device for the computer has good visual effect and clear pictures and good in light transmission rate and vision.
Description
Technical field the utility model belongs to the computer shield technical field, relates to the anti-information leakage device of a kind of computer shield.
Background technology is present, and along with science and technology development, computer application has spread to the various aspects of people's life, and electromagenetic wave radiation has caused people's attention to the injury of human body.Though existing computer protecting screen also just shields to the display front on the market, the electromagnetic wave of its side and back surface radiation can't shield.Be harmful to health of human body, relating to special sectors such as military affairs, national defence in addition needs the electromagnetic information of computing machine not revealed, and it is far from being enough that protection screen only is set.
The summary of the invention the purpose of this utility model is to solve prior art to have the technical matters of electromagnetic wave to personal injury, electromagnetic information leakage and the harassing and wrecking of outside forceful electric power magnetic, provides a kind of computer shield to prevent the information leakage device.
The utility model computer shield is prevented the information leakage device, comprises wire gauze, and its main points are to be respectively equipped with one deck polycarbonate film in the wire gauze both sides, and the polycarbonate film outside adheres to one deck glass sheet respectively, and hot pressing is into a single integrated structure.
Described wire gauze leaves the wide shirt rim of 2～5cm in described glass sheet periphery, and described wire gauze is 300 order silk screens, and the mesh wire diameter of wire gauze is 0.02mm.
The utility model is applicable to the visual windows of electromagnetic shields such as computing machine electromagnetic screen machine room, computing machine electromagnetic protection machine table, server electromagnetic protection rack, can effectively suppress information leakage and anti-electromagnetic interference (EMI), stopped the injury of electromagnetic wave, effectively suppressed the computing machine electromagnetic information and revealed and prevent the technical matters that outside forceful electric power magnetic is harassed human body.Have good visual effect, transmittance is good, visual sense is good, picture and text are clear.
Description of drawings Fig. 1 is the utility model master TV structure synoptic diagram;
Fig. 2 is the plan structure synoptic diagram of Fig. 1.
Among the figure: 1, wire gauze shirt rim 2, glass 3, polycarbonate film 4, wire gauze
Embodiment sees figures.1.and.2, and the utility model comprises wire gauze 4, and the both sides of wire gauze 4 are respectively equipped with one deck polycarbonate film 3, and polycarbonate film 3 outsides adhere to one deck glass sheet 2 respectively, and hot pressing is into a single integrated structure; Wire gauze 4 leaves the wide shirt rim of 2～5cm 1 in glass sheet periphery, and wire gauze 4 is 300 order silk screens, and the mesh wire diameter of wire gauze 4 is 0.02mm.
Computer shield provided by the utility model is prevented the information leakage device, be applied to electromagnetic screen equipment visual windows, it is wide to be suitable for frequency range, the requirement of foot GB BMB3-1999B level and national military standard GJBZZ20219-94B level, under 60 centimeters mensurations, when frequency was 14K, 200K, 450M, 930M, screen was imitated and is reached 24dB, 94dB, 76dB respectively, can be used as a kind of high, visual good light-transmission type electromagnetic screen of effect that shields.
Claims (2)
