ABSTRACT:
An EMI shielding device is set in an electronic device. The electronic device includes a shell, a circuit board set in the shell, and an electrical component set on the circuit board. The shielding device includes a middle board and a shielding cover. The middle board is set inside the electronic device. The shielding cover is set on the middle board and covers an outside of the electrical component. Thus, the EMI shielding device is structured. The material of the shielding cover is widely used, so the cost of the material is markedly reduced. After the shielding cover is opened, it is easy to restore the shielding state. The shielding cover is set inside the electronic device via the middle board, so assembly is easy and it is not limited by changes in the shape or the structure of the shell, so applicability is improved.
