Abstract:
An electromagnetic interference shielding enclosure, comprising:(a) a plurality of interconnected walls made of electrically conductive material and being arranged in a polygonal configuration to surround an electronic component on a substrate, each of said walls having an upper portion and a lower portion extending in opposite directions;(b) an upper releasable attachment arrangement formed in said upper portions of said respective walls and adapted for engagement with a top cover in a first orientation, said upper releasable attachment arrangement including an upper plurality of outer and inner tabs disposed in spaced, alternating and offset relationship with respect to one another along said upper portions of said walls so as to create an upper annular channel between said upper outer and inner tabs extending along said upper portions of said walls, said upper annular channel being open from above so as to adapt said upper annular channel to receive a downward extending edge of the top cover in said upper annular channel in engagement between said upper outer and inner tabs; and(c) a lower releasable attachment arrangement formed in said lower portions of said respective walls and adapted for engagement with a bottom cover in a second orientation being the inverse of the first orientation of the top cover, said upper and lower releasable attachment arrangements being substantially mirror images of one another.
