Problems solved by technology

The shielding effect of this method is moderate, but the cost is low, and the volume is relatively small, the scope of application is wide, and both units and individuals can be used; but the biggest defect of the above method is that it is heavy and inconvenient to move
Ordinary computer host interface does not adopt professional electromagnetic protection, and lacks relevant protective equipment, which brings safety hazards to the overall protection of the computer system. Electromagnetic pulses can be coupled into the computer through keyboards, mice, interfaces and their connecting lines. Indirectly cause interference or damage to the computer; at the same time, the electromagnetic information radiated by the chassis is also easy to be captured, and information leakage occurs, causing potential safety hazards

Abstract

The invention discloses an electromagnetic shielding machine case which is composed of a machine case housing (1), side panels (9), waveguide windows, an aviation plug (8) and a power filter (12). Two side panels (9) are arranged on choke grooves (13) on two lateral sides of the machine case housing (1) respectively, the aviation plug (8) and the power filter (12) are arranged in the machine case housing (1), and a front side panel (6) and a rear side panel (11) are respectively provided with a waveguide window to achieve a purpose of efficient shielding. The electromagnetic shielding machine case is clear in structure and good in practicality, achieves the purposes of being convenient to move, high in shielding efficiency, safety and reliability, good in environment adaptation and wide in application range, solves the problems of computer damage caused by electronic pulse and electromagnetic information leaking and is suitable for military and confidential situations.

Description

technical field [0001] The invention relates to the field of electromagnetic protection technology (electromagnetic shielding technology), and mainly relates to an electromagnetic shielding cabinet. Background technique [0002] As we all know, with the continuous development and progress of science and technology, microelectronic equipment has been widely used in various military equipment and civilian products, especially computers have penetrated into all walks of life and become indispensable in military equipment and civilian products. The lack of equipment plays a pivotal role. On the other hand, the rapid development and application of high-energy electronics, pulse power technology and antenna technology make it possible to use conventional energy to generate a strong electromagnetic pulse environment. Studies have shown that this strong electromagnetic pulse can cause serious interference or damage to electronic equipment and systems in this environment. In ...
