Electromagnetic Compatibility (EMC), which is a abbreviation of EMC, means that an electronic device does not interfere with other devices, and is not affected by other devices. Electromagnetic compatibility, as well as safety, is one of the most important indicators of product quality. Security relates to personal and property, while electromagnetic compatibility relates to personal and environmental protection.

Electromagnetic shielding in a certain region of the space, means for reducing the field strength caused by certain sources. In most cases, the shield can be made of metal such as copper, aluminum, steel, etc., but for constant and very low frequency magnetic fields, materials such as ferrite can also be used as the shield.

In the shelter, the steel plate of the electromagnetic shielding shelter has the same inner and outer skin materials due to the need of protecting equipment in the shelter. The inner skin and the outer skin are both made of aluminum to achieve electromagnetic shielding, however, the square cabin is weak in electromagnetic shielding function, the inner skin and the outer skin of the other scheme are made of steel, and the problems that the cabin body is too heavy, the corrosion resistance is insufficient and the like exist in the square cabin.

In some embodiments, the inner skins are connected by a seam weld.

In some embodiments, the inner skin is acid-washed phosphated steel.

In some embodiments, the skeleton is standard vertebra aluminum.

The utility model discloses the beneficial effect who has does:

1. according to the utility model discloses an electromagnetic shield shelter cabin board fills the foaming honeycomb panel between the skeleton, all bonds with the glued membrane between foaming honeycomb panel, skid and the interior outer skin, and the skid passes through fix with rivet with the skeleton. Because the inner skin is acid-washing phosphated steel, the electromagnetic shielding function is strong, and the outer skin is conductive alumina, the corrosion resistance is strong, and the lightweight can be realized.

2. The foamed honeycomb plate has strong bearing capacity and can bear strong extrusion force.

3. The framework is made of standard aluminum, so that the weight of the deck plate can be reduced.

4. The glue film is adopted, so that the glue consumption can be conveniently controlled, and the weight increase of the cabin plate caused by excessive gluing and accumulation is avoided.
