Abstract
A method for mounting a fingerstock EMI shielding gasket on a sheet metal structure includes the steps of forming tabs which protrude from the surface of the sheet metal structure. The shielding gasket, which has a generally D-shaped cross section with at least one mounting tab forming at least part of an upright portion therefor, is inserted into position longitudinally between the tabs.
Claims31
A method for mounting a fingerstock EMI shielding gasket on a sheet metal structure, said shielding gasket having a generally D-shaped cross section with at least one mounting tab forming at least part of an upright portion therefor, said method comprising the steps of:
- a) forming at least one outer tab from said sheet metal structure, said outer tab protruding outwardly from a surface of said sheet metal structure;
- b) forming at least one inner tab from said sheet metal structure, said inner tab protruding outwardly from said surface of said sheet metal structure, said inner tab being oriented generally toward said outer tab and being laterally separated therefrom;
- and
- c) sliding said fingerstock EMI shielding gasket longitudinally between said inner and outer tabs with said mounting tab of said shielding gasket being inserted beneath said inner tab thereby securing said shielding gasket between said inner and outer tabs.
A method for mounting a fingerstock EMI shielding gasket on a metal structure, said shielding gasket having a generally D-shaped cross section with at least one mounting tab forming at least part of an upright portion therefor, said method comprising the steps of:
- a) forming at least one outer tab integrally with said metal structure, said outer tab protruding outwardly from a surface of said metal structure;
- b) forming at least one inner tab integrally with said metal structure, said inner tab protruding outwardly from said surface of said metal structure, said inner tab being oriented generally toward said outer tab and being laterally separated therefrom;
- and
- c) sliding said fingerstock EMI shielding gasket longitudinally between said inner and outer tabs with said mounting tab of said shielding gasket being inserted beneath said inner tab thereby securing said shielding gasket between said inner and outer tabs.
A method related to 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 therefore, the method comprising:
- forming at least one outer tab from the sheet metal structure, the at least one outer tab protruding outwardly from a surface of the sheet metal structure, and
- forming at least one inner tab from the sheet metal structure, the at least one inner tab protruding 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 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 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 and at least one outer tab that protrude outwardly from a surface of the sheet metal structure and that are 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 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 has 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.
