Abstract

Disclosed is a formed metal grounding spring extending around a portion of a plastic guide into which a peripheral device, such as a DASD (Direct Access Storage Device) unit is mounted within a personal computer. The spring provides an electrical ground connection simultaneously contacting the peripheral device, a metal bracket retaining the device bezel, and a wall of a metal frame of the computer, thereby reducing RFI (Radio Frequency Interference).

Grounding Spring for Peripheral Device and Bezel Bracket

      Disclosed is a formed metal grounding spring extending around a
portion of a plastic guide into which a peripheral device, such as a
DASD (Direct Access Storage Device) unit is mounted within a personal
computer.  The spring provides an electrical ground connection
simultaneously contacting the peripheral device, a metal bracket
retaining the device bezel, and a wall of a metal frame of the
computer, thereby reducing RFI (Radio Frequency Interference).

      As shown in the Figure, a plastic rail 10, mounted on a wall 12
extending into a computer frame 14, provides a side of a channel into
which a peripheral device (not shown) may be slid.  As the peripheral
device is slid into place, corresponding guiding surfaces (not shown)
of the peripheral device slide between a pair of guiding ledges 15
extending inward from rail 10.  A bracket 16, used for retaining one
or more bezels (not shown) covering the front portion(s) of
peripheral unit(s), is mounted to pivot upward on frame 14, in the
direction of arrow 18, into a closed position.

      A formed metal grounding spring 20 is slipped around a section
21 of plastic rail 10, to be held in place by the attachment of rail
10 within frame 14.  (A portion of the upper guiding ledge 15 has
been cut away in the figure to reveal the shape of spring 20.)  A
flat portion 22 of spring 20 extends along a surface of frame wall
12, with a formed end tab 24 ext...
