Abstract

As computer systems become more compact, the mounting of major compacts, such as Direct Access Storage Devices (DASDs), for example, hard disk drives, is an important factor in determining accessibility to planar boards and other components. It also affects the ventilation and electronic compatibility of the system.

Mounting for Direct Access Storage Device Components

      As computer systems become more compact, the mounting of major
compacts, such as Direct Access Storage Devices (DASDs), for example,
hard disk drives, is an important factor in determining accessibility
to planar boards and other components.  It also affects the
ventilation and electronic compatibility of the system.

      A mounting system for one or more DASD devices which allows
easy access to the devices themselves and to other components, while
meeting the strength, Electromagnetic Compatibility (EMC), and
ventilation requirements of the system in which the devices operate,
is shown in the Figure.

      Referring to the Figure, the DASD device or devices are mounted
in a cage (3) provided with a pair of mounting lugs (9) arranged to
cooperate with a hinge bracket (2) on the system unit frame (10) so
as to permit attachment of the cage (3) to the frame (10) by means of
a hinge pin (1).

      EMC flanges (4) are fitted both to the frame and the DASD cage
so as to allow physical contact between the surfaces when the cage
(3) is installed in the operating position, thus, ensuring a good EMC
seal between the cage and the frame.

      The hinge pin is used to attach the cage to the hinge bracket
and hence, to the frame.  The hinge pin can be positioned so that
when the exterior cover is refitted to the system, the pin will not
work loose but is securely retained in position.  The hinge pin...
