Dynamic zero clearance 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
• housing bezel, disposed relative to said cassette housing in a cable opening thereof so as to be associated with said cable opening and translatable therein, said housing bezel in electrical communication with said printed circuit card and translatable therewith to engage said printed circuit card with a printed circuit board via said mounting device;
• and
• an EMC sealing device disposed between said housing bezel and said cassette housing, said EMC sealing device configured to provide a movable EMC seal proximate said cable opening while still allowing airflow therethrough while covering a portion of said cable opening created between said housing and said housing bezel upon translation of said bezel.

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 slidably associated with said cable opening, wherein said housing bezel including a plurality of openings in the top of said housing bezel for the flow of cooling air;
• an EMC sealing device providing an EMC seal between said cassette housing and said housing bezel, said EMC sealing device configured to provide thermal protection via openings therein and an electromagnetic conduction seal to said printed circuit card translatable with said housing bezel;
• and
• a plurality of vents formed on one side of said wall coacting with said plurality of openings in the top of said housing bezel and said openings of said EMC sealing device to aid air flowing through said housing and providing electromagnetic shielding for said circuit card positioned within.
