RF Shielded electronic component housing

An electronic component housing comprising:

• a base member formed of a relatively non-deformable electrically conductive material defining an interior chamber opening to the exterior through an access aperture;
• an electrically conductive cover plate formed of a relatively deformable material dimensioned to extend over said access aperture;
• said base member including around the periphery of said access aperture a ledge portion dimensioned to receive said cover plate;
• and
• said base member further including a plurality of engaging elements on said ledge portion in interference with the rim of said cover plate, said cover plate being deformed by said engaging elements to form a plurality of closely spaced mechanical and electrical engagement point providing a mechanical and electrically secure mounting for said cover plate.

An electronic component housing comprising:

• a base member cast of a relatively non-malleable material defining an interior chamber opening to the exterior through an access aperture;
• a cover plate member formed of a relatively malleable material dimensioned to extend over said access aperture;
• said base member including around the periphery of said access aperture a flange portion dimensioned to receive said cover plate;
• and
• said base member further including a plurality of closely spaced integrally formed engaging elements on said flange portion arranged for engaging said cover plate on said flange portion whereby said cover plate is mechanically and electrically secured to said base member.
