Shielding coverIt is a metal casing used for shielding electromagnetic interference. It is usually made of high-strength metal materials and protects internal equipment and materials from interference by shielding electromagnetic interference inside.
The principle of the shielding cover is to shield electromagnetic interference from the outside, thereby protecting internal equipment and materials from interference. The material of the shielding cover is usually made of metal materials such as stainless steel, aluminum, copper, etc., which have good thermal conductivity and corrosion resistance.
There are many types of shielding covers, including switch cabin type, shell type, embedded type, etc. In industrial applications, shielding covers are often used to manufacture various types of equipment and systems to ensure their reliability and safety.
Shielding covers can not only be used to shield electromagnetic interference, but also to protect internal equipment and materials from interference, thereby improving the reliability and safety of the system. In modern industry, shielding covers have become an essential part, providing strong protection for industrial production.
1、 What is a shielding cover?
A shielding case is one of the hardware components in electronic computers. It is made of metal or plastic mesh to prevent external signals from interfering with and damaging the internal circuits of electronic computers.
Shielding coverFunction:
1. Prevent external interference, such as electromagnetic radiation, etc;
2. Suppress external noise, such as electroacoustic interference, etc;
3. Reduce damage from external devices to internal circuits and protect internal electronic components.
1. Metal plate made of aluminum or iron. This type of structure is simple, cost-effective, and easy to use. But its heat dissipation performance is poor, and it is easy to produce hot spots, causing local temperatures to be too high. In addition, due to the easy oxidation of aluminum materials, a thin oxide film is easily generated in the air. This oxide film will absorb some energy, affecting its heat dissipation function. Therefore, when the ambient temperature is high, it will cause the surface temperature of the component to rise and even burn out. So, attention should be paid to rust prevention treatment during use.
2. Aluminum alloy plate. This type of structure is slightly more complex than the former, but its heat dissipation performance has been improved. Because connecting aluminum plates together with copper strips forms a whole, it can greatly improve their thermal conductivity. At the same time, the surface of the copper strip is also coated with a thin layer of silver, which can effectively prevent oxidation from occurring.
Lead tin alloy plateThis type of structure is more complex than the previous two, but it has good corrosion resistance.
3. Composite type. This is currently the most widely used one. It uses two different materials of boards combined to form a complete whole. Among them, one is a metal and the other is a non-metallic material. For example, using lead tin alloy instead of pure aluminum.
4. Plastic type. This is an ideal shielding device. Because it has good insulation and corrosion resistance.
5. Ceramic type. This is a new type of high-tech material. It is made by mixing calcium silicate powder with a small amount of binder and die-casting.
6. Rubber type. This is made using the elastic properties of rubber. It can withstand significant mechanical stress. However, its sealing performance is poor.
7. Fiber reinforced plastic (glass fiber) type. It is designed and manufactured using the elastic properties of fiberglass.
2、 How to install and use correctly?
Select appropriate products and install them according to the instructions. When using, avoid external impacts to prevent damage to the product. Regularly check the condition of the product and replace it immediately if there is any damage.
Overall, a shielding cover is a metal shell that plays an important role in effectively shielding electromagnetic interference, ensuring the reliability and safety of equipment and systems. With the continuous development and improvement of technology, shielding covers are also constantly being updated and improved. New efficient and reliable shielding shells continue to emerge, providing better protection and support for industrial production.
The application of shielding covers in modern industry is becoming increasingly widespread, providing strong protection and support for industrial production. I believe that in the future, shielding covers will play a more important role in industrial production, providing more reliable, safe, and efficient protection and support for industrial production.
