Circuit board component shielding enclosure and assembly

An electromagnetic interference shielding enclosure, comprising:

• (a) a plurality of interconnected walls made of electically conductive material being arranged in a polygonal configuration to surround an electronic component on a circuit board, each of said walls having a lower portion and an upper portion extending upwardly from said lower portion;
• (b) a plurality of mounting pins made of an electrically conductive material and being attached to said lower portions of said respective walls and extending downwardly from lower edges thereon for attachment to the circuit board;
• and
• (c) a plurality of inner and outer tabs formed in said upper portions of said respective walls, said inner and outer tabs being disposed in spaced, alternating and offset relationship with respect to one another along said upper portions of said walls so as to create an annular channel between said inner and outer tabs extending along said upper portions of said respective interconnected walls, said inner tabs in said upper portion of a respective one of said walls being integrally connected to said lower portion of said wall and extending in an offset fashion inwardly and upwardly therefrom.

An electromagnetic interference shielding assembly, comprising:

• (a) an elongated enclosure made of an electrically conductive material and having a plurality of interconnected walls arranged in a polygonal configuration to surround an electronic component on a circuit board, each of said walls having a lower portion and an upper portion extending upwardly from said lower portion;
• (b) a plurality of mounting pins attached to said lower portions of said respective walls and extending downwardly from lower edges thereon for attachment to the circuit board;
• (c) a plurality of inner and outer tabs formed in said upper portions of said respective walls, said inner and outer tabs being disposed in spaced, alternating and offset relationship with respect to one another along said upper portions of said walls so as to create an annular channel between said inner and outer tabs extending along said upper portions of said respective interconnected walls of said enclosure, said annular channel being open from above;
• and
• (d) a cover made of electrically conductive material and having a top portion and a plurality of side portions attached to and extending downwardly from said top portion and arranged in a polygonal configuration matching that of said interconnected walls of said enclosure, said side portions of said cover being removably inserted downwardly into said annular channel defined by said inner and outer tabs and into a frictional fitting relation therewith to thereby removably mount said cover over said enclosure and provide an electromagnetic interference shield for the electronic component.
