Problems solved by technology

Because this structure is relatively simple, it can only be applied to low-frequency electromagnetic shielding, and often cannot pass the electromagnetic compatibility test
In actual use, it is easy to cause electromagnetic interference with other electromagnetic equipment
Therefore, the traditional shielding structure can no longer meet the shielding requirements in complex electromagnetic environments

Abstract

The invention provides an electro magnetic compatibility shielding box which comprises a shielding shell and an inner shell, wherein the inner shell is arranged in the shielding shell; the shielding shell sequentially comprises a glass fiber layer, a plastic layer and a shielding layer from inside to outside; double surfaces of the plastic layer are plated with metals, and the shielding layer is made from an electromagnetic wave absorbing material; the inner shell is made from an aluminum alloy plate, the inner shell is mutually spaced with the shielding shell and is connected and fixed together with the shielding shell through a support frame, the part between the inner shell and the shielding shell is filled with conductive foam; and the inner shell and the shielding shell are provided with openable and closable shielding doors, the position of the shielding door on the inner shell corresponds to the position of the shielding door on the shielding shell, the shielding door on the inner shell is made from the aluminum alloy plate, and the shielding door on the shielding shell is consistent to the shielding shell in structure. By adopting the mode, the electro magnetic compatibility shielding box provided by the invention has good electro magnetic compatibility shielding function and is suitable for shielding various electromagnetic waves.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility shielding, in particular to an electromagnetic compatibility shielding box. Background technique [0002] Traditional EMC shielding devices usually only use one layer of metal plate to make the shielding cavity. Because this structure is relatively simple, it can only be applied to low-frequency electromagnetic shielding, and often fails to pass the electromagnetic compatibility test. In actual use, it is easy to cause electromagnetic interference with other electromagnetic equipment. Therefore, the traditional shielding structure can no longer meet the shielding requirements in complex electromagnetic environments. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an electromagnetic compatibility shielding box, which can have a good electromagnetic compatibility shielding function and is suitable for shielding v...
