Pluggable Flex Circuit to Flex Circuit With Contact Wipe

       Disclosed is a mechanical means of connecting two flex
circuits together and also providing contact wipe.

      One flex circuit 1 which contains gold-plated contact pads
.016" X .060") for wipe, is bonded to print head 2.  The second flex
circuit 3 is bonded to the print head carrier 4, after placing the
four elastomer pressure pads 5 in place, as shown in Fig. 1.  Flex
circuit 3 also has gold-plated contact pads (e.g., .008" X .060") for
wipe.  (Gold-plated hertz dots may be used on the gold contact pads
of flex circuit 3 to obtain the required contract forces.)

      Cuts 6 are made in flex circuit 3 to allow flex circuit 1 and
print head 2 to force the gold contact pads of flex circuit 3 against
the elastomer pressure pads 5.  This provides approximately 50 grams/
contract pad.

      The flex circuits and print head are aligned very accurately by
the pins 7 in the print head carrier 4.
