Abstract

This article describes a metal bracket designed for personal computer (PC) system I/O cards which acts as a handle for card insertion and extraction and also adds stiffness to enhance the structural and electro-magnetic compatibility (EMC) integrity of the system I/O port.

Card Handle

       This article describes a metal bracket designed for
personal computer (PC) system I/O cards which acts as a handle for
card insertion and extraction and also adds stiffness to enhance the
structural and electro-magnetic compatibility (EMC) integrity of the
system I/O port.

      Typically, support is provided only for those applications
which have a connector attached to the PC I/O card bracket.  Cards
without a connector, such as memory expansion and hard file
controller cards, have no rear support and are prone to come out of
the system I/O port (not shown), creating an EMC exposure.

      Fig. 1 shows a PC I/O card and the handle of this disclosure in
exploded perspective view.  Fig. 2 shows the handle attached to the
card.  Handle 1 is designed such that it fits directly behind the I/O
card bracket 2.  It supports the PC I/O card bracket 2 so that EMC
contacts 3 stay within and in contact with the metallized system I/O
port.  The handle 1 is attached to the PC I/O card with two identical
length rivets 4.  The material thickness of the handle is greater
than that of the rivets.  This provides a stronger attachment joint
and improved EMC contacts.
