Dynamically moveable exhausting EMC sealing system

A docking apparatus comprising:

• a printed circuit card;
• a cassette housing having a mounting device and defining a housing cavity for movably containing said printed circuit card, said mounting device is disposed within said housing cavity so as to slidingly contain said printed circuit card within said housing cavity;
• and
• a housing bezel having a plurality of openings and a removable EMC gasket configured to removably seal against EMC and allow airflow to said printed circuit card disposed within said housing cavity so as to be in communication with said printed circuit card while providing an EMC seal when said outer bezel is removably engaged with said cassette housing.

An apparatus for providing a thermal protection and electromagnetic conduction seal in a docking apparatus having a printed circuit card disposed therein for connection to a system backplane, said apparatus comprising:

• a conductive cassette housing, having a housing base, a housing cover and a housing wall, wherein said housing base and said housing wall are disposed relative to each other so as to define a housing cavity for containing a printed circuit card and wherein said housing wall includes a cable opening disposed so as to be communicated with said housing cavity and a connector opening for a connector exposed in said connector opening for mating and connection with the system backplane;
• a housing bezel, wherein said housing bezel is disposed relative to said cassette housing so as to be associated with said cable opening, wherein said housing bezel is removable, said housing bezel including a plurality of openings in the top of said housing bezel for the flow of cooling air;
• an EMC gasket providing an EMC seal between said top of said cassette housing and a bottom surface of said top of said housing bezel, said EMC gasket configured to provide thermal protection and electromagnetic conduction seal to said printed circuit card;
• and
• a plurality of vents formed on one side of said wall coacting with said plurality of openings in said plurality of openings in the top of said housing bezel to aid air flowing through said housing and providing electromagnetic shielding for said circuit card positioned within.
