Abstract:
An electronic isolation shield for mounting on a circuit board and having an upper and lower surface around an electronic component to provide a minimum amount of shielding over a set period of time, said shield comprising:a body made from a shielding material sized and shaped to fit around and over said electronic component, said body having a sealing edge that is adapted to contact the upper surface of said circuit board and surround said electronic component; andmeans for forcing said sealing edge of said body into sealing engagement with said upper surface of said circuit board, said means comprising a plurality of resilient downwardly projecting tabs attached to said body and each of said tabs including a securing end that extends past said sealing edge, each of said tabs being securable to said circuit board along a securing axis; said forcing means being responsive to lateral displacement of said tabs with respect to said securing axis;said tabs each having a planar surface at an angle to and in contact with the lower surface of said circuit board for laterally displacing a portion of said tab with respect to said securing axis continuously over said set period of time so that said forcing means forces said sealing edge into said circuit board sufficiently to provide said minimum amount of shielding to said electronic component over said set period of time, a cross-sectional area of said tabs measured in a plane parallel to and disposed above said sealing edge is greater than a cross-sectional area of said tab measured in a plane parallel to and disposed below said sealing edge.
