Electromagnetic radiation containment in an electronic module

An electronic module, comprising:

• a housing;
• a printed circuit board partially positioned within the housing and defining an edge connector extending from the housing;
• and
• an electrically conductive sealing element radially surrounding 360 degrees of one end of the housing and the printed circuit board proximate the edge connector such that when the edge connector is fully received in a host board connector mounted to a host board, the electrically conductive sealing element cooperates with a corresponding structure of the host board to at least partially define a Faraday cage substantially enclosing the edge connector and the host board connector, wherein the housing defines a radial groove which aids in the retention of the sealing element.

A host board, comprising:

• a printed circuit board;
• a ground plane attached to the printed circuit board;
• a host board connector attached to the ground plane;
• and
• an electrically conductive shroud mounted to the ground plane and substantially enclosing the host board connector, the electrically conductive shroud defining an opening by way of which an edge connector of an electronic module can be received, the electrically conductive shroud being devoid of other unsealed openings that are large enough for electromagnetic radiation to escape therethrough, the electrically conductive shroud sized and shaped to cooperate with a corresponding structure of the electronic module to form a Faraday cage substantially enclosing the edge connector and the host board connector.
