Abstract:
A shielding device for reducing electromagnetic emissions from an electronic device which includes an electronic component, an electrically conductive housing that houses the electronic component and that includes a shielding wall with opposite inner and outer shielding wall surfaces, the outer shielding wall surface having an access opening extending to communicate with the inner shielding wall surface so as to expose the electronic component from the outside of the electronic device, and a mounting member that is disposed to mount the electronic component relative to the inner shielding wall surface and that includes a mounting wall forming a clearance with the inner shielding wall surface as a result of anchoring attachment between the mounting member and the inner shielding wall surface, said shielding device comprising:an abutment segment extending in a longitudinal direction and having an inner abutment surface, and an outer abutment surface opposite to said inner abutment surface in a transverse direction that is transverse to the longitudinal direction, said outer abutment surface being adapted to abut against one of the mounting member and the inner shielding wall surface; an intermediate segment extending from said abutment segment and terminating at a distal end, said intermediate segment having an intermediate inner surface spaced apart from said inner abutment surface in the transverse direction to confine a compressible space therebetween, and an intermediate outer surface opposite to said intermediate inner surface in the transverse direction and joining said intermediate inner surface at said distal end; a shielding segment extending from said distal end and terminating at an engaging portion which is spaced apart from said intermediate segment in the transverse direction by a route for passage of possible electromagnetic emissions and which is adapted to engage the other one of the mounting member and the inner shielding wall surface so as to shield the clearance from the route, said shielding segment, said abutment segment and said intermediate segment being formed from an electrically conductive material; and an electrically conductive deformable member having opposite first and second force bearing surfaces, said deformable member being received in said compressible space such that said first and second force bearing surfaces respectively abut against said intermediate inner surface and said inner abutment surface, thereby enhancing strength and resiliency of said intermediate segment and said abutment segment.
