Abstract

Described is a rear panel mechanical design for use in a personal computer system frame assembly. The panel is designed to provide a continuous ground for all input/output (I/O) connectors attached to a planar board and to add overall structural integrity to the rear of the system. Also, the panel provides aesthetics as a decorative rear cover in both color and texture.

Rear Panel Design for Personal Computer Systems

      Described is a rear panel mechanical design for use in a
personal computer system frame assembly.  The panel is designed to
provide a continuous ground for all input/output (I/O) connectors
attached to a planar board and to add overall structural integrity to
the rear of the system. Also, the panel provides aesthetics as a
decorative rear cover in both color and texture.

      Fig. 1 is an isometric view of a system's frame assembly with
rear panel 10 positioned just prior to installation onto the frame
assembly. Rear panel 10 includes shadow box area 11, ground ribs 12
(right side and left side) and rear frame grounding ribs 13.  Shadow
box area 11 contains four self-centering slots 14 that align, guide
and support channel circuit cards (not shown).  Slot 15 is provided
for the system's processor card (not shown).  Latch 16 is a
cantilevered latching device used during the insertion and extraction
of the processor card and is required due to heavy forces associated
with as many as 328 contacts.

      Ground ribs 12 make contact with the top cover shield (not
shown) so as to provide the required grounding.  Frame grounding is
accomplished through the use of three system screws 17.  Four
metallic thumb screws 18 protrude through the windows at the base of
shadow box area 11 to provide the required ground contact between I/O
brackets 19 and rear panel 10.
