Abstract
Aspects of the present disclosure provide methods for mounting fingerstock EMI shielding gaskets on sheet metal structures. The fingerstock EMI shielding gasket may include a generally D-shaped cross section with at least one mounting tab forming at least part of an upright portion. In one particular exemplary embodiment, a mounting method generally includes providing a sheet metal structure with inner and outer tabs which protrude outwardly from a surface of the sheet metal structure. The inner tabs may be oriented generally toward the outer tabs and may be laterally separated from the outer tabs. The shielding gasket may be slidably inserted into position longitudinally between the inner and outer tabs.
Claims20
A method for mounting a fingerstock EMI shielding gasket on a sheet metal structure, the fingerstock EMI shielding gasket having a generally D-shaped cross section with at least one mounting tab forming at least part of an upright portion thereof, the method comprising:
- attaching at least one outer tab to a sheet metal structure such that the at least one outer tab protrudes outwardly from a surface of the sheet metal structure;
- attaching at least one inner tab to the sheet metal structure such that the at least one inner tab protrudes outwardly from the surface of the sheet metal structure, the at least one inner tab being oriented generally toward the at least one outer tab and being laterally separated therefrom;
- and
- sliding the fingerstock EMI shielding gasket longitudinally between the at least one inner tab and the at least one outer tab with the at least one mounting tab of the fingerstock EMI shielding gasket being positioned beneath the at least one inner tab thereby securing the fingerstock EMI shielding gasket generally between the at least one inner tab and the at least one outer tab.
A method for mounting a fingerstock EMI shielding gasket on a sheet metal structure, the shielding gasket having a generally D-shaped cross section with at least one mounting tab forming at least part of an upright portion thereof, the method comprising:
- providing at least one outer tab that protrudes outwardly from a surface of the sheet metal structure;
- and
- providing at least one inner tab that protrudes outwardly from the surface of the sheet metal structure, the inner tab being oriented generally toward the outer tab and being laterally separated therefrom so as to allow sliding of the fingerstock EMI gasket longitudinally between the inner and outer tabs with the at least one mounting tab of the fingerstock EMI shielding gasket being positioned beneath the at least one inner tab of the sheet metal structure, to thereby secure the fingerstock EMI shielding gasket generally between the inner and outer tabs of the sheet metal structure.
A method for mounting a fingerstock EMI shielding gasket on a sheet metal structure, the shielding gasket having a generally D-shaped cross section with at least one mounting tab forming at least part of an upright portion thereof, the method comprising:
- providing at least one outer tab that protrudes outwardly from a surface of the sheet metal structure;
- and
- providing at least one inner tab that protrudes outwardly from the surface of the sheet metal structure, the inner tab being oriented generally toward the outer tab and being laterally separated therefrom so as to allow sliding of the fingerstock EMI gasket longitudinally between the inner and outer tabs with the at least one mounting tab of the fingerstock EMI shielding gasket being positioned beneath the at least one inner tab of the sheet metal structure, to thereby secure the fingerstock EMI shielding gasket generally between the inner and outer tabs of the sheet metal structure;
- wherein the sheet metal structure is provided by attaching the inner and outer tabs to the sheet metal structure and without leaving apertures in the sheet metal structure.
A method for mounting a fingerstock EMI shielding gasket on a sheet metal structure, the fingerstock EMI shielding gasket having a generally D-shaped cross section with at least one mounting tab forming at least part of an upright portion thereof, the sheet metal structure having at least one inner tab attached thereto and at least one outer tab attached thereto, the inner and outer tabs protruding outwardly from a surface of the sheet metal structure and being aligned longitudinally in a direction parallel to an edge of the sheet metal structure, the inner and outer tabs being laterally separated, the method comprising:
- sliding the fingerstock EMI shielding gasket longitudinally between the inner and outer tabs with the at least one mounting tab of the fingerstock EMI shielding gasket being positioned beneath at least one inner tab of the sheet metal structure, thereby securing the fingerstock EMI shielding gasket generally between the inner and outer tabs of the sheet metal structure;
- wherein the fingerstock EMI shielding gasket includes a second mounting tab, the second mounting tab forming part of an upright portion of the generally D-shaped cross section, and wherein the sheet metal structure further includes at least one anti-snag tab oriented in the same general direction as the at least one outer tab, the at least one anti-snag tab being laterally separated from the inner and outer tabs and laterally farther from the at least one outer tab than from the at least one inner tab, and wherein sliding the fingerstock EMI shielding gasket includes positioning the second mounting tab of the fingerstock EMI shielding gasket generally beneath the at least one anti-snag tab, whereby the anti-snag tab helps hold the second mounting tab down on the surface of the sheet metal structure.
