Shield assembly with gaskets

A shielding assembly for protecting a plurality of electrical modules from electromagnetic interference, the shielding assembly comprising:

• a cage installable on a circuit board, the cage comprising a front end portion, a cover, a base, a receiving room formed between the cover and the base, and at least one interior wall, the cover, the interior wall, and the base cooperatively defining at least two spaces for receiving the modules;
• a conductive first gasket encircling the front end portion of the cage, the first gasket electrically and mechanically contacting the cover and the base to provide an electromagnetic interference seal between the cage and a device in which the cage is mounted;
• and
• an electrically-conductive, compressible second gasket received in the receiving room and attachable against the cage and the circuit board respectively so as to electrically shield the modules in the cage from electromagnetic interference;
• wherein the cover comprises a top wall, a pair of first sidewalls and a first rear wall, and the base comprises a bottom wall, a pair of second sidewalls, and a second rear wall, wherein the first sidewalls and the first rear wall overlap the second sidewalls and the second rear wall respectively when the cover and the base are assembled together;
• and wherein each of the first sidewalls and the first rear wall comprises a main body depending from the top wall, a skirt parallel to the main body and a step connecting the main body and the skirt.

An assembly for shielding an electronic module therein from electromagnetic interference, comprising:

• a conductive cage defining a space therein for receiving said electronic module, first sidewalls, a first rear wall, second sidewalls, a second rear wall, and a receiving room defined between the first sidewalls and the first rear wall and the second sidewalls and the second rear wall, and accessible from an entrance facing said circuit board;
• and
• an electrically-conductive compressible gasket installable into said receiving room from said entrance and extending out of said receiving room toward said circuit board, said gasket physically and electrically engaging with said cage and said circuit board simultaneously so as to provide electrically shielding between said cage and said circuit board;
• wherein each of the first sidewalls and the first rear wall comprises a main body depending from the top wall, a skirt parallel to the main body and a step connecting the main body and the skirt.
