Abstract

PS/2* MICRO CHANNEL* machines have a limited number of slots for the addition of Adapter Cards. In order to add more function to Adapter Cards, it is possible to design Base Adapter Cards which can contain one of several Secondary Cards. Since Secondary Cards may require different external interfaces, the Base Adapter must accommodate a number of external connectors. An Adapter Bracket is shown which allows the flexibility of using Secondary Cards while maintaining mechanical strength and Electromagnetic Interference (EMI) shielding of the present Adapter Bracket.

Multiconnector PS/2 MICRO Channel Adapter Bracket

       PS/2* MICRO CHANNEL* machines have a limited number of
slots for the addition of Adapter Cards.  In order to add more
function to Adapter Cards, it is possible to design Base Adapter
Cards which can contain one of several Secondary Cards.  Since
Secondary Cards may require different external interfaces, the Base
Adapter must accommodate a number of external connectors.  An Adapter
Bracket is shown which allows the flexibility of using Secondary
Cards while maintaining mechanical strength and Electromagnetic
Interference (EMI) shielding of the present Adapter Bracket.

      Fig. 1 shows the Multiconnector PS/2 MICRO CHANNEL Common
Bracket, which has the same mechanical outline as the standard PS/2
MICRO CHANNEL Bracket (*), but has an added hole to allow a variety
of connectors mounted on Secondary Cards to pass through it.  Also
shown in Fig. 1 is a Blank Bracket which provides mechanical strength
and EMI shielding when no Secondary Card is installed on the Common
Bracket. The Blank Bracket can be held in place on the Common Bracket
by thumb screws.

      Fig. 2 shows a Secondary Card Bracket configured with a 37-pin
D-shell connector.  To install a Secondary Card, the Blank Bracket is
removed and the Secondary Card with its bracket is attached to the
Base Adapter Card. The Secondary Bracket also provides mechanical
strength and EMI shielding with the Common Bracket. The Secondary
Card Bracket can...
