Abstract
A receptacle assembly is provided having a gasket interposed between a heat sink and the receptacle, in order to provide EMI shielding and limit leakage from an opening in the receptacle that allows the heat sink to engage an electronic module inserted in the receptacle cavity. The heat sink may have a groove in which the gasket is mounted and upon mounting the heat sink to the receptacle, the gasket surrounds the opening in the receptacle and provides a resilient shield to maintain a seal during movement of the heat sink due to insertion of the electronic module within the receptacle.
Claims20
A receptacle assembly, comprising:
- a receptacle formed by walls joined to form an interior cavity configured to receive an electronic module, one of the walls having an opening therethrough;
- a heat sink mounted over the opening, the heat sink having an abutment surface located adjacent the opening and the abutment surface of the heat sink being configured to physically contact the receptacle;
- and
- a gasket surrounding the opening and disposed between the receptacle and the heat sink adjacent the abutment surface, in order to reduce leakage of radiation from the opening.
A receptacle assembly, comprising:
- a receptacle having walls joined to form an interior cavity configured to receive a pluggable module, one of the walls having an opening therethrough;
- a covering component mounted over the opening, the covering component having an abutment surface located proximate the receptacle and a gap formed between the abutment surface and the receptacle;
- and
- a gasket disposed in the gap in order to seal the gap and prevent radiation from escaping from the opening.
A heat sink for mounting to a Faraday cage, the heat sink comprising:
- an upper portion for dissipating heat;
- a lower portion having a planar abutment surface formed at least around an outer perimeter of the lower portion;
- a groove formed in the outer perimeter;
- and
- a gasket mounted in the groove and the gasket for sealing a gap formed between the abutment surface and the Faraday cage to which the heat sink is mounted.
