Abstract
The RF shielding of electronic devices with a frame and sheet metal structure to form coverings for the electrical parts characterized by the structure having planar parts provided with springs to insure contact between the metal parts. Each of the springs has a pair of tabs which are connected to a center portion by a pair of bent portions having bends in at least two directions to form humps or arcuate portions. The springs are secured to the planar part by having the ends extending through a pair of apertures with the tabs engaging one side of the planar part and the center portion contacting an abutment surface between the apertures to insure that the bent portions curve above the outer surface. The abutment in the planar part may include an aperture and the center portion may have a bent nose that extends into the aperture. In another embodiment, the center portion is bent to form a nose portion which engages a web forming the abutment.
