Preventing the Simultaneous Attachment of a Card and Cable to a Circuit
Board

      Disclosed is a structure allowing the attachment of either a
circuit card or a cable to a circuit board while preventing the
simultaneous attachment thereto of the card and cable.

      Fig. 1 is an isometric view of a circuit board (4) in an
exploded relationship with a circuit card (6), which is plugged into
the circuit board (4) as a connector plug (8) is inserted into a
first connector receptacle (10).  When the circuit card (6) is
installed in this way, physical access to a second connector (12) on
the circuit board (4) is blocked by a section (14) of the circuit
card (6) extending  adjacent to the pins (16) of the second connector
(12).

      Fig. 2 is an isometric view of the circuit board (4) in an
exploded relationship with a cable (18), which is alternately
installed on the circuit board (4) as a cable connector (20) is
pressed onto the  pins (16) of the second connector (12).  When the
cable (18) is installed  in this way, the circuit card (6) cannot
additionally be installed into  first connector receptacle (10) since
the cable connector (20) physically  blocks the card section (14).

      Thus, this structure allows the individual installation of
either of two devices to the circuit board (4), using separate
connectors on the board (4), while preventing their simultaneous
attachment. This  structure can be used to prevent overloading power
circuits or...
