Abstract

Disclosed is a hardware implementation to provide the required electro-magnetic compatibility (EMC) grounding and shielding of disk access drive device (DASD) units when mounted into a personal computer (PC) chassis. The implementation uses support slides that are strategically located along with "Z" shaped snap lock type of retainers that provide a wiping action to ensure good grounding of the DASD units.

Method to Provide Grounding/Shielding for Disk Drive Devices

      Disclosed is a hardware implementation to provide the required
electro-magnetic compatibility (EMC) grounding and shielding of disk
access drive device (DASD) units when mounted into a personal
computer (PC) chassis.  The implementation uses support slides that
are strategically located along with "Z" shaped snap lock type of
retainers that provide a wiping action to ensure good grounding of
the DASD units.

      As higher frequency operational PC systems come on-line,
additional importance is place on the importance of meeting EMC
requirements.  DASD units are typically of the removable type and
therefore require special attention to ensure that EMC requirements
are met.  The concept describe herein provides a method whereby the
DASD units will engage with mounting slides and retainers in order to
provide the required grounding and shielding to meet EMC
requirements.  Support slides and retainers are the critical
components utilized in the design.

      Fig. 1 is an isometric view of the front housing that holds the
DASD units.  Left support slides 1 and right support slides 2 are
fixed to frame 3 so as to enable the DASD units to slide into
position.  "Z shaped retainers 4 are used to provide a wiping action
and retention when engaged in corresponding DASD "Z" shaped retainers
(shown in Fig. 3).

      Fig. 2 shows an isometric view of the rear section of frame 3
and the front of th...
