Single-Piece Contact Strip for Personal Computer Grounding and Shielding

      Described is a hardware implementation that provides a single
piece contact strip for use on personal computer (PC) housings to
enable systems to meet electro-magnetic grounding and shielding
requirements.

      Certain PC systems utilize removable top covers which have long
slots at the rear of the cover between the cover and the base.  The
slots will allow electronic noise interference to radiate from the
unit and must be provided with a grounding strip.

      Prior art utilized copper contact strips with an adhesive
backing which adhered to the base of the unit and made contact with
the top cover.  However, the small contact area available for the
adhesive to adhere caused the contact strips to fall off.  The
concept described herein replaces the adhesive type of strip so as to
provide an improved design that would not require adhesives or
pressure during assembly, but still provided the required grounding
and shielding.

      Fig. 1 shows the single piece contact strip 10 that replaces
the prior art adhesive type of design.  Single piece contact strip 10
contains contact fingers and a base section.  Fig. 2a shows an
isometric view of contact strip 10 as it would be positioned to
housing unit 11.  For reference, Fig. 2b shows input/output (I/O)
panel 12 as it would be positioned into housing unit 11.  Fig. 2c
shows cover 13 as it would be positioned over housing unit...
