Multi-Port Connector Adapter and Cabling for Personal Computers

       A mechanism is described whereby a multi-port connector
adapter and cabling system enables more than four external cables to
be plugged into a single personal computer (PC) communications
adapter card.

      In prior art, PC systems provided limited input/output (I/O)
connector space.  Typically, only one or two cables could be plugged
into a single adapter card.  With the advances in integrated
circuitry, more communications functions can be placed on a single
card, thereby requiring additional external cabling.  The mechanism
described herein provides the user the ability to order an additional
set of cables to connect up to eight devices (eight signal lines per
device) to any seventy-eight pin "D" shell multi-port adapter.  More
than eight devices could be connected if the interface required less
than eight lines.

      Connector adapter assembly 10, as shown in Fig. 1, contains
seventy-eight pin "D" connector 11 and eight shielded eight pin
telephone jacks 12, all soldered to PC card 13.  The assembly is
enclosed in a poly-vinyl chloride (PVC) overmold incorporating copper
tape for electro-magnetic compatibility (EMC) shielding.  Two
thumbscrews 14 are used to secure the ends of connector 11 to a PC
adapter card connector.

      Up to eight shielded cables 15 can be plugged into connector
adapter telephone jacks 12.  The other ends of the cables are
connected to peripheral...
