Stainless Steel Reusable Grounding Strips for Personal Computer Systems

      Described is a hardware implementation that provides a
stainless steel grounding 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 stainless steel contact strip 10
that replaces the prior art adhesive type of design.  Single piece
stainless steel contact strip 10 contains contact fingers 11 as part
of a base section.  Fig. 2a shows a sectional view of housing 12.
Fig. 2b shows power supply unit 13 and how contact strip 10 would be
positioned to housing unit 12 (Fig. 2a) and power supply unit 13 and
held in place with the use of screw 14.  Fi...
