Claim 10

The bulk head gasket assembly of claim 7 further comprising: an aperture in said first bulk head side wall; a tab extending outward from said first gasket side wall, said tab positioned and adapted to snap fit into said aperture in said first bulk head side wall to retain said gasket in said bulk head recess when said gasket is snap fit into said bulk head.

Claim 11

The bulk head gasket assembly of claim 7 further comprising a through hole in said gasket base plate disposed to line up with a through hole in said bulk head base plate when said gasket is snap fit into said bulk head recess, said through hole in said gasket base plate and said through hole in said bulk head base plate providing access to the interior of a shielding enclosure when said bulk head gasket assembly is disposed over a port in said shielding enclosure.

Claim 12

The bulk head gasket assembly of claim 7 wherein said distal spring finger section includes an inner fold over bend at said distal edge of said distal spring finger section.

Claim 13

The bulk head gasket assembly of claim 7 adapted for providing EMI shielding at an interface between a printed circuit board and a card drive port in a panel of a computer chassis.

Claim 14

The bulk head gasket assembly of claim 7 wherein said first gasket side wall forms an angle slightly greater than ninety degrees with said gasket base plate such that said first gasket side wall is spring loaded against said first bulk head side wall when said gasket is inserted into said bulk head recess.

Claim 15

A bulk head gasket assembly for providing EMI shielding at a port in a panel of a shielding enclosure, said bulk head gasket assembly comprising: a bulk head including a bulk head base plate and first and second bulk head side walls, said first and second bulk head side walls positioned at right angles to said bulk head base plate such that a bulk head recess is formed, said first bulk head side wall having a bulk head aperture formed there through; a gasket, adapted to snap fit into said bulk head recess, such that said gasket lines the interior surface of said bulk head base plate, and said first and said second bulk head side walls, said gasket further comprising; a gasket base plate and first and second gasket side walls extending from said gasket base plate, said first gasket side wall forming an angle slightly greater than ninety degrees with said gasket base plate such that said first gasket side wall is spring loaded against said first bulk head side wall when said gasket is inserted into said bulk head recess, a tab extending outward from said first gasket side wall, said tab positioned and adapted to snap fit into said bulk head aperture to retain said gasket in said bulk head recess, a spring finger integral with said second gasket side wall and extending outward from a distal edge of said second gasket side wall, said spring finger including a spring bend between a proximal spring finger section and a distal spring finger section wherein said distal spring finger section includes an inner fold over bend at said distal edge of said distal spring finger section, said spring finger being buttressed by said second bulk head side wall which slips between said second gasket side wall and said spring finger so that said spring finger is prevented from being bent inward to a state of perpetual deformity; and a through hole in said gasket base plate disposed to line up with a through hole in said bulk head base plate when said gasket is snap fit into said bulk head recess, said through hole providing access to the interior of a shielding enclosure when said bulk head gasket assembly is disposed over a port in said shielding enclosure.
