Deflectable contact for providing positive surface contact for shielding electromagnetic interference

Claim 1

In a personal computer assembly including a housing having an electromagnetic interference shield panel mountable on one surface thereon adjacent a front surface of at least one electronic device mounted on a movable support, the improvement comprising: said shield panel having a first contact spaced from said support and said electronic device; said support being a base having an upper surface and a lower surface, said upper surface having said electronic device mounted thereon; and a grounding connector mounted on said support and providing a low resistivity grounding path between said electronic device and said shield, said grounding connector comprising conductive means and a second contact; said conductive means being mounted on said support between said upper surface of said base and said electronic device, said conductive means being mechanically and electrically connected to a ground connection of said electronic device; and said second contact extending from said base into grounding electrical engagement with said first contact, said second contact being connected to said conductive means, and said second contact being deflectable and deformable by said first contact between a first position and a second position, for providing a line contact with said first contact when in said first position, and for providing a low resistivity surface contact in which said second contact is deformed against said first contact to provide greater contact surface area than said line contact when deflected into said second position by pressure exerted thereon by said first contact and said electromagnetic interference shield panel, when said personal computer assembly is fully assembled, to provide enhanced shielding against electromagnetic interference.
