FIELD: radio engineering.
SUBSTANCE: invention relates to the field of radio engineering, in particular to shielding devices. The shielding device is a box consisting of a load-bearing aluminum frame and doors made by welding. A ground screw is installed in the lower part of the frame. A shielding network is installed on the frame, fixed with aluminum rivets and soldering by means of tension corners with a reliable galvanic contact. Sandwich panels with shielding material are installed on top of the network. Perforation is applied to the panel to remove hot air from the box. There are technological holes with wicker braid for input and output cables on the box. Conductive gaskets are installed on the door and frame using conductive glue to ensure a single shielding circuit.
EFFECT: technical result is an increase in the reliability of information protection against unauthorized access and information loss through side electromagnetic radiation and interference in a wide frequency range.
