Abstract

To achieve electro-magnetic conductive properties on polymer cover panels, aluminum foil is combined with a conductive gasket and retention clip. An aluminum foil or foil composite, with or without perforations is applied to the back of the cover with the foil on the outside. The foil extends into or across molded-in grooves. A spring clip contacts the foil in the groove. A continuous conductive path is developed through a conductive gasket attached to the clip. Various gasket and clip configurations are used to maintain continuity between covers or cover and metal frame.

Electro-Magnetic Conductive System for Polymer Cover Panels

      To achieve electro-magnetic conductive properties on polymer
cover panels, aluminum foil is combined with a conductive gasket and
retention clip.  An aluminum foil or foil composite, with or without
perforations is applied to the back of the cover with the foil on the
outside.  The foil extends into or across molded-in grooves.  A
spring clip contacts the foil in the groove.  A continuous conductive
path is developed through a conductive gasket attached to the clip.
Various gasket and clip configurations are used to maintain
continuity between covers or cover and metal frame.

      An alternate retention method involves capturing an extrusion
in the groove.  A conductive gasket fits into the extrusion and
captures the foil.  For cover-to-cover contact, the extrusion would
extend around the edge of the cover to contain a conductive gasket.
