ABSTRACT:
An electromagnetic shielding device includes a metal frame mounted on a circuit board and having a looped surrounding wall configured with an inner space divided into first and second space portions by a partition wall unit. A cover is mounted fittingly into the inner space in the metal frame, and includes a dielectric cover body, and a conductive material layer attached to an outer surface of the cover body. The cover body has a looped surrounding wall extending downwardly from a periphery of a top wall and disposed in proximity to the looped surrounding wall of the metal frame such that the conductive material layer is in electrical contact with the looped surrounding wall of the metal frame. The cover cooperates with the metal frame to define first and second cavities having different depths and corresponding respectively to the first and second space portions.
