Do you know what factors affect the isolation of the shielding box?

Author:admin   AddTime:2021-05-05

The shielding box is a shielding body of various shapes, such as shells, plates, and sleeves made of conductive or magnetic materials. The shielding cabinet is a special part of it. It is one of the strongest electromagnetic radiation protection capabilities. A large metal body whose electromagnetic capability is limited to a certain space is used to suppress radiated interference, and it is a device that provides a non-interference and spacious test environment for wireless communication equipment.

The absorbing rubber and absorbing sponge are good materials for processing radiation. Generally, these two materials are used to make shields. And the cost is also low and affordable.



Shielding strips, beryllium, copper shrapnel shielding cabinets and shielding boxes have a common requirement, that is, to ensure good conductivity continuity can ensure good shielding effect, not to mention the efficiency requirements of shielding cabinets are higher than that of shielding boxes. This just makes up for the integration of the new requirements of the shielding box on the contact surface of the upper and lower covers of the box. If other places are done well, the shielding effectiveness is low.

Shielding box design elements
The design of the shielding cabinet is based on the design requirements of the shielding box body and the addition of copper shrapnel to ensure the continuity of its conductivity and prevent the product surface finish and contact tightness from being affected. At present, there are many modes in the market: die-casting, casting, sheet metal welding, etc. Die-casting boxes can better ensure the adhesion of the material molecular gap and ensure better electrical continuity. The surface of the casting is processed, and the sheet metal Although gold welding omits the process of surface treatment, the isolation of the egg is likely to be reduced in terms of welding contact, and the requirements for butt processing are relatively high. Poor processing will affect the isolation of the shield, that is, the service life. Therefore, it should be noted that the cabinet design should be grounded.
