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 electromagnetic compatibility shielding cabin. The electromagnetic compatibility shielding cabin includes a shielding shell and an inner shell inside the shielding shell. The shielding shell includes a glass fiber layer, a double-sided metal-plated plastic layer and a shielding layer made of electromagnetic wave absorbing material from the inside to the outside. The inner shell is made of aluminum Made of alloy plate, the inner shell and the shielding shell are separated from each other, and are connected and fixed with the shielding shell through brackets. The gap between the inner shell and the shielding shell is filled with conductive foam, and the inner shell and the shielding shell are equipped with a shielding door that can be opened and closed. , and the position of the shield door on the inner shell corresponds to the position of the shield door on the shield shell. The structure of the shielded door is consistent with that of the shielded enclosure. Through the above method, the present invention can have a good electromagnetic 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 cabin. 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 cabin, which can have a good electromagnetic compatibility shielding function and is suitable for shieldi...
