EMI shielding assemblies and related methods of retaining components thereof together

An electromagnetic interference (EMI) shielding apparatus comprising:

• a shield having a surface and at least one thru-hole in the shield;
• and
• a gasket securable to the surface of the shield, the gasket haying a peripheral edge portion, the gasket including at least one support located inwardly of the peripheral edge portion of the gasket and at least one wing formed depending outwardly from the at least one support, the at least one wing located inwardly of the peripheral edge portion of the gasket;
• the at least one wing frictionally engageable within the at least one thru-hole pre-existing in the shield, to thereby help locate the gasket relative to the shield, at least initially mechanically secure the gasket directly to the shield, and retain the relative positioning of the gasket to the shield.

An electromagnetic interference (EMI) shielding apparatus comprising:

• a shield having a surface and at least one thru-hole in the shield;
• and
• a gasket including at least one support, at least two flaps depending outwardly from the at least one support and defining a wing connector, and at least one resilient spring finger along a surface of the gasket generally opposite the flaps;
• the at least two flaps are frictionally engageable within the at least one thru-hole pre-existing in the shield, to thereby help locate the gasket relative to the shield, at least initially mechanically secure the gasket directly to the shield, and retain the relative positioning of the gasket to the shield;
• the at least one resilient spring finger configured for contacting a printed circuit board to provide an electrical grounding pathway between the gasket and the printed circuit board.

A gasket for attachment to an electromagnetic interference (EMI) shielding structure having at least one pre-existing opening, the gasket comprising:

• a peripheral edge portion;
• at least one support formed monolithically with the gasket and located inwardly of the peripheral edge portion;
• at least one flap formed monolithically with the gasket and attached to the support, the at least one flap located inwardly of the peripheral edge portion;
• wherein the at least one flap is configured to be moved relative to the support generally away from the gasket and at least partly into at least one pre-existing opening of an EMI shielding structure, and wherein such movement of the at least one flap at least partly secures the gasket to the shield.
