Abstract

This article features a wrap-around enclosure which provides an excellent EMI/EMC containment method as well as a means of obtaining structural strength to support heavy video monitors (excess of 90 pounds). Since the outer enclosure is essentially one piece, it does not exhibit conventional cover problems such as: gaps to emit EMI leakage, multi fasteners to assemble, or costly interstructures for video monitor support.

Wrap Around Enclosure for Personal Computer/Workstation

       This article features a wrap-around enclosure which
provides an excellent EMI/EMC containment method as well as a means
of obtaining structural strength to support heavy video monitors
(excess of 90 pounds).  Since the outer enclosure is essentially one
piece, it does not exhibit conventional cover problems such as: gaps
to emit EMI leakage, multi fasteners to assemble, or costly
interstructures for video monitor support.

      The wrap-around outer cover (Fig. 1) is open at the front and
rear ends with a "C-section" form across the top rear to provide
rigidity (Fig. 2).  A rigid front bezel is permanently attached to
the front end opening.  A stamped chassis on which all the components
are mounted (Fig. 3) slides into the rear opening completing the
enclosure.

      Unique features of this design are: (1) excellent EMI
containment for packaged electronics/power supply, (2) economical,
practical method of supporting large, heavy monitors without internal
supports, and (3) method of obtaining access to all functional
components without time-consuming cover removal.  Chassis removal is
by simply depressing the latch handle and sliding out the unit.
Chassis removal with heavy monitor placed on top of the computer does
not degrade the ease of removal in any way.  All external cabling can
remain attached in functional state during chassis removal.

      Also, this type of cover design along w...
