Abstract:
1. An electromagnetic shielding device adapted to be disposed on a circuit board, comprising: a metal frame adapted to be mounted on the circuit board and including a looped surrounding wall configured with an inner space, and a partition wall unit connected to said looped surrounding wall for dividing said inner space into at least first and second space portions; and a cover mounted fittingly into said inner space in said metal frame, said cover including a dielectric cover body having an outer surface, and a conductive material layer attached to said outer surface of said dielectric cover body, said dielectric cover body having a top wall, and a looped surrounding wall extending downwardly from a periphery of said top wall and disposed in proximity to said looped surrounding wall of said metal frame such that the conductive material layer is in electrical contact with said looped surrounding wall of said metal frame, said cover cooperating with said metal frame so as to define at least first and second cavities corresponding respectively to said first and second space portions of said inner space in said metal frame, said first and second cavities having different depths; wherein said partition wall unit of said metal frame includes a partition wall; wherein said partition wall of said metal frame has a top end formed integrally with a plurality of positioning pins that are spaced apart from each other; and wherein said top wall of said dielectric cover body of said cover is formed with a plurality of positioning holes that are spaced apart from each other and that engage fittingly and respectively said positioning pins of said partition wall of said metal frame.
