Electronic assembly having sealing retainer coupling an electronic module and associated method

A sealing retainer to be coupled between a chassis and an electronic module, the chassis having a plurality of electronic module mounting positions and each electronic module mounting position having a chassis cooling gas passageway, the electronic module having a module cooling gas passageway, a module recess adjacent a first end thereof, and a module roller adjacent a second end thereof opposite the first end, the sealing retainer comprising:

• a rigid retainer body having a top surface and opposing lower surface, and a retainer recess formed on the top surface adjacent a first end thereof to receive the module roller when the electronic module is in an inserted position, the rigid retainer body having a first cooling gas passageway to be aligned with the module cooling gas passageway;
• a roller cutout formed within the top surface of the rigid retainer body adjacent a second end thereof opposite the first end, a retainer roller carried within the roller cutout and configured such that a top section of the retainer roller extends above the top surface, said retainer roller received in the module recess when the electronic module is in the inserted position;
• a compressible retainer body between the lower surface of the rigid retainer body and the chassis and having a second cooling gas passageway to be aligned with the chassis cooling gas passageway;
• and
• a sealing gasket carried by the rigid retainer body on a side thereof opposite the compressible retainer body.

A method of mounting an electronic module in an electronic module mounting position of a chassis, the electronic module mounting position having a chassis cooling gas passageway, and the electronic module having a module cooling gas passageway, a module recess adjacent a first end thereof, and a module roller adjacent a second end thereof opposite the first end, the method comprising:

• coupling a sealing retainer between the chassis and the electronic module, the sealing retainer comprising
• a rigid retainer body having a top surface and opposing lower surface, and a retainer recess formed on the top surface adjacent a first end thereof to receive the module roller when the electronic module is in an inserted position, the rigid retainer body having a first cooling gas passageway to be aligned with the module cooling gas passageway,
• a roller cutout formed within the top surface of the rigid retainer body adjacent a second end thereof opposite the first end, a retainer roller carried within the roller cutout and configured such that a top section of the retainer roller extends above the top surface, said retainer roller received in the module recess when the electronic module is in the inserted position,
• a compressible retainer body between the lower surface of the rigid retainer body and the chassis and having a second cooling gas passageway to be aligned with the chassis cooling gas passageway;
• and
• a sealing gasket carried by the rigid retainer body on the top surface.
