FIELD: radio engineering; electromagnetic radiation shields for radio electronic equipment. ^ SUBSTANCE: proposed device has base, casing, top cover, front panel, mask, and metal screen; novelty is that its front panel is framed over perimeter by electromagnetic packing. Mask is provided with angle piece fixed thereto over perimeter. Metal screen is secured over perimeter on frame mounted for ensuring contact pressure on electromagnetic packing. Points of contact between frame and packing, the latter and mask angle piece, mask and framing, the latter and electromagnetic packing, as well as between packing and casing edge are covered with conducting material. ^ EFFECT: reduced access to secret information. ^ 1 cl, 5 dwg |
