Abstract

Adapter cards for conventional personal computer applications have required an ever increasing number of input/output (I/O) signals to the mother board. To provide for a more manufacturable system, many designers have chosen I/Os on a 0.050" spacing on the adapter card's edge. The adapter cards can provide upwards in the 300+ I/O's for communication with the mother board.

Interconnect Between Adjacent Connectors

      Adapter cards for conventional personal computer applications
have required an ever increasing number of input/output (I/O) signals
to the mother board.  To provide for a more manufacturable system,
many designers have chosen I/Os on a 0.050" spacing on the adapter
card's edge.  The adapter cards can provide upwards in the 300+ I/O's
for communication with the mother board.

      The fundamental problem now faced by designers, and more
importantly the card assemblers, is the interconnect to the adapter
card's edge.  Traditional card edge connectors are limited to around
200 I/Os due to traditional molding technologies.  Hence, several
connectors must successfully mate with the adapter card's edge.

      This disclosure documents a technique for providing the
necessary alignment between the two or more connectors on the mother
board so they will mate with the adapter card and provide the
necessary I/Os for communication.  An interlocking system would make
otherwise independent connectors act as one during the assembly
process. Traditionally, the solder tails of a connector are placed in
holes in the mother board that are usually twice the tail's size.
This slop allows the connectors considerable room to move during the
assembly process.  An interlocking mechanism between the connectors
would allow the adjacent connectors to be more linear which would
facilitate mating to the adapter card.
