The key to the design of the shielding box is to meet two coordinations. One is that the two wings of the shielding box body and a locking device are matched with the slot of the reinforced machine chassis. The second is the matching of the printed motherboard sockets in the shielding box. Therefore, the design of the shielding box must ensure that the printed board of the shielding box can be inserted into the motherboard slot accurately and correctly, and at the same time ensure that the two wings of the shielding box have a good fit with the slot of the reinforced machine chassis.
Inferior shielding equipment may interfere with the normal operation of other electronic equipment due to production process and design defects, but professional mobile phone shielding equipment for professional occasions will never interfere with the normal operation of other electronic equipment. This is because professional mobile phone shielding equipment is not simple. The patchwork of circuit boards is a fully enclosed modular structure. Each shielding module corresponds to a mobile phone signal frequency band. When the mobile phone shielding device is working, each shielding module only interferes with its own corresponding frequency band and will never have any impact on other electronic devices.
Shielding is the metal isolation between two spatial areas to control the induction and radiation of electric fields, magnetic fields and electromagnetic waves from one area to another. Specifically, the shielding box is used to surround the components, circuits, assemblies, cables or the entire system interference source to prevent the interference electromagnetic field from spreading; the shielding box is used to surround the receiving circuit, equipment or system to prevent them from being exposed to the external electromagnetic field influences.
