An electromagnetic compatibility box

Abstract

The invention provides an electromagnetic compatibility box. The box comprises an outer box and an inner box arranged in the outer box, and a shielding cavity is formed between the outer box and the inner box. A plurality of partition plates are arranged in the shielding cavity and divide the shielding cavity into a plurality of sub-shielding cavities, wherein the interior of each sub-shielding cavity is provided with a shielding layer; a horizontal partition plate is arranged in the inner box and divides the inner box into an upper heat dissipation cavity and a lower installation cavity. Theinvention has the beneficial effects that the structural strength of the box can be enhanced, and a good electromagnetic compatibility shielding function is achieved; the box is suitable for shieldingvarious electromagnetic waves; meanwhile, the rain-proof and heat dissipation functions are achieved, and the adverse effects of dust on installed electrical or electronic equipment can be effectively prevented in the heat dissipation process.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility, in particular to an electromagnetic compatibility box. Background technique [0002] Electromagnetic Compatibility The ability of various electrical or electronic equipment to meet the design requirements with a specified safety factor in a space with a complex electromagnetic environment, also known as electromagnetic compatibility, its meaning includes: First, the electromagnetic compatibility between electronic systems or equipment The mutual consideration in the environment; the second is that the electronic system or equipment can work normally in accordance with the design requirements in the natural electromagnetic environment. [0003] However, traditional EMC shielding devices usually only use one layer of metal plate to make the shielding cavity. Because this structure is relatively simple, it is only suitable for low-frequency electromagnetic shielding, and often...

[0003] However, traditional EMC shielding devices usually use only 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 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
