Embodiment Construction

[0029] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0030] as attached figure 1 And attached figure 2 As shown, the window is composed of a metal window frame 60 and a plexiglass window plate 50 , and the window frame 60 is embedded in the shielding shell 1 . In this embodiment, the shielding case 1 is the door of the clean room, and the surface of the door is a layer of continuous metal color steel plate as the shielding case 1 . The window frame 60 is an annular metal frame, and its outer boundary is fully welded with the shielding shell 1 to ensure that the conduction between the two is complete and uninterrupted. The window panel 50 has two layers, covering the inside and outside sides of the opening surrounded by the window frame 60 respectively. The inner boundary of the window frame 60 protrudes toward the opening, so an annular mounting surface 65 capable of fitting the window panel 50 is formed on ...

Abstract

The invention relates to a window for a clean room with a function of electromagnetic shielding, which comprises at least one layer of transparent luffer board which is embedded into a shielding shell of the clean room. The window also comprises at least one metal mesh and at least one annular panel, wherein the metal mesh completely covers the luffer board, and the whole boundary of the metal mesh contacts the shielding shell by means of electric conduction; and the panel completely covers a joint of the luffer board and the shielding shell and is simultaneously hermetically connected with the luffer board and the shielding shell. The clean shielding window meets the B-level index of the shield effectiveness and has wide application scope. The mounting structure of the window can not influence the cleanliness of the clean room; the sealing principle of the window is basically the same as that of a common clean room; and the transparency of the window is between 30 and 80 percent by selection of different metallic shielding windows according to different requirements of shielding levels.

Description

technical field [0001] The invention relates to a window for a clean room which simultaneously functions as an electromagnetic shielding room. Background technique [0002] The rapid development of the electronic industry has led to the widespread popularization and application of various electronic devices, which release a large amount of electromagnetic radiation while facilitating human work. On the one hand, a large amount of electromagnetic radiation will endanger people's health, and on the other hand, it will also interfere with the micro-current control signals inside other electronic products, causing errors or paralysis in the operating systems of some precision electronic equipment. In addition, the divergence of electromagnetic radiation also brings hidden dangers to information security. Computers and other scientific research equipment will leak useful information through electromagnetic waves during work, resulting in information leakage, which may cause major...
