Abstract
A snap-fit shield is provided which fits securely within a frame opening, and which shields and grounds the opening while eliminating a need for a complementary connector portion. The shield has an insulative inner housing having a first base wall and a first pair of side walls and end walls extending therefrom defining a first cavity. The shield includes a conductive shell having a second base wall and a second pair of side walls and end walls extending therefrom defining a second cavity. The second pair of side walls and end walls have at least one outward bias positioned thereon. The shield also has an insulative outer housing having a third base wall and a third pair of side walls and end walls extending therefrom defining a third cavity. The outer housing is configured to snap-fit within an opening in a frame so as to shield circuitry internal thereto. The third cavity of the outer housing is configured to receive at least a portion of the conductive shield therein, while the second cavity of the conductive shield is configured to receive the inner housing therein.
