Problems solved by technology

The existing technology is to fill the gap with conductive elastic material, eliminate the non-conductive point or contact the metal shell and the metal cover through the elastic metal contact piece to form a complete metal shell for electromagnetic shielding, but this electromagnetic protection method is not effective during use. Due to the use environment such as vibration and shock, the contact will not be ...

Abstract

The invention provides an electromagnetic protection device, and the device comprises a protection shell, a protection cover, a protected assembly, a connector and a shielding cover. The protective shell is fixedly connected with the protective cover to form a first space; the protected assembly is located in the first space, and the connector is connected to one end of the protected assembly; theshielding case isolates the protected assembly from the connector; the protective cover is provided with a first protective part close to the shielding cover, the first protective part is provided with at least one groove, and the end, close to the protective cover, of the shielding cover is contained in the first protective part. A second protection part is arranged at the position, close to theshielding cover, of the protection shell and provided with at least one groove, and the end, close to the protection shell, of the shielding cover is contained in the second protection part. According to the technical scheme, the problem of electromagnetic radiation and interference resistance of electronic devices such as electronic devices and PCBs can be effectively solved, and electromagneticprotection is achieved.

Description

technical field [0001] The invention relates to the field of electromagnetic protection, in particular to an electromagnetic protection device. Background technique [0002] Electronic devices, circuit boards and other electronic equipment will be interfered by electromagnetic signals in the surrounding environment during work and cannot work accurately. At the same time, electronic equipment will also radiate electromagnetic waves to the surrounding environment during work, thereby interfering with the normal work of other electronic equipment. Therefore, electronic equipment that has high requirements on signals or is susceptible to interference, such as the field of automotive electronic equipment, generally requires electromagnetic protection design to shield electromagnetic radiation and not radiate electromagnetic waves to ensure stable and accurate operation of the circuit. The principle of electromagnetic shielding is to shield the far field of the radiation interfer...
