Method and apparatus for capping and grounding an electrical connector to prevent leakage of electromagnetic interference

A method for limiting leakage of electromagnetic interference through an electrical connector, said electrical connector having a conductive shell and a non-conductive insert, said electrical connector disposed over a penetration that extends through a panel of a chassis, said panel adapted to serve as chassis ground, said conductive shell of said electrical connector connected to said panel such that said conductive shell is electrically tied to chassis ground, said method comprising:

• providing at least one piece comprised of a material that is adapted to block electromagnetic interference, said at least one piece defining an aperture that is adapted to receive a conductor that extends from said electrical connector through said penetration in said panel;
• substantially covering said penetration in said panel with said at least one piece;
• and
• connecting and electrically tying said at least one piece to said conductive shell of said electrical connector;
• wherein said at least one piece is adapted to limit leakage of electromagnetic interference into and out of said chassis through said penetration and said non-conductive insert of said electrical connector.
