Platte zur elektromagnetischen Abschirmung.

摘要

An electromagnetic shielding panel (1, 2, 3, 4, P5) incorporates at least two electroconductive coatings (10 and 6, 7,8). In two of the panels (1,2) the coatings are carried on separate sheets of float glass (5,9), one of the coatings 10 being an anti-abrasive coating is on the outermost surface of the glass (9) in the panel arrangement, while the other coating (6,7,8) being a relatively soft abrasive-sensitive coating, e.g. silver, is on the innermost of the glass 5 in the panel arrangements. In other panel arrangements (3,4,P5) the two coatings are located on opposing sides of one glass sheet 9 and on two of the panels (3,4) a plain sheet of float glass (11) is employed to protect the soft silver coating (6,7,8). In another panel (P5) a sheet of glass (9) carrying an anti-abrasive coating (10) is employed. The panels are of the double glazed type (Fig. 1, Fig. 3, Fig. 5) and the laminated type (Fig. 2, Fig. 4). This invention utilises the enhanced capacitive coupling (C) between the two coatings (10 and 6,7, 8) to effectively earth the innermost silver coating (6,7,8) by way of the anti-abrasive coating 10 without any direct electrical connection being required to be made to the innermost coating (6,7,8).
