The utility model belongs to the technical field of
electromagnetic shielding, particularly relates to a multilayer nested high-frequency
electromagnetic shielding device, and aims to solve the problems that a single-layer box body of an existing device is extremely limited in high-frequency
electromagnetic wave absorption capacity, a large amount of high-frequency
electromagnetic interference is only simply reflected, the reflected electromagnetic
waves are repeatedly refracted inside and outside the box body, and complex standing
waves are formed. In order to solve the problems that the
electromagnetic interference intensity in a box body cannot be effectively reduced and the complexity of an
electromagnetic environment is aggravated, the utility model provides the following scheme: the multi-layer nested high-frequency
electromagnetic shielding device comprises a shielding base, and an inner-layer shielding body, a middle-layer shielding body and an outer-layer shielding body are sequentially nested on the surface of the shielding base from inside to outside; the beneficial effects of the utility model are that the design of nesting in sequence from inside to outside enables each layer of shielding body to work cooperatively, weakens high-frequency
electromagnetic interference layer by layer, and compared with a single-layer shielding structure, can cope with a complex high-frequency
electromagnetic environment more comprehensively and efficiently, and significantly improves the
shielding effect.
