Circuit board component shielding enclosure and assembly having opposing covers interfitted with upper and lower portions of enclosure

摘要

An electromagnetic interference shielding assembly includes an enclosure and top and bottom covers. The enclosure has interconnected walls arranged in a polygonal configuration to surround an electronic component on a circuit board. Each wall has upper and lower portions extending in opposite directions. The enclosure has upper and lower releasable attachment arrangements respectively formed in the upper and lower portions of the walls and releasably engaged with the top and bottom covers. The upper and lower attachment arrangements are substantially mirror images of one another and define upper and lower annular channels that are open respectively from above and below. Each of the top and bottom covers has a main portion and side portions attached to and extending from the main portion and arranged in a polygonal configuration matching that of the walls of the enclosure. The side portions of top and bottom covers are removably inserted into the corresponding upper and lower annular channels and into frictional fitting relation with the upper and lower portions of the enclosure to thereby removably mount the covers to the enclosure.
