Zipper Connector

      As circuit boards require circuitry of greater density,
the need for a connector system to accommodate tighter lines and
spaces arises.  Disclosed is a description of such a connector that
employs zipper technology.

      The zipper connector has two rows of teeth that are meshed with
a clasp.  The mechanical interlocking holds two separate entities
together.  By alternating metal teeth and insulated teeth, a system
for connecting two circuits can be economically realized.  The figure
shows a typical arrangement.  The dark teeth are metallic (e.g., gold
plated copper) and are fastened to a flex cable similar to standard
zipper teeth.  The ends of the teeth connect to lines on the flex
cable and are soldered for guaranteed electrical connection.  The
shaded teeth are insulated (e.g., plastic) teeth that separate
circuits and also form part of the locking system.  These teeth are
fastened to bare spots on the flex cable.  When the clasp is moved in
the fastening direction, the edges of the teeth are forced together
with a "wiping" action.

      The result is a low-cost, low-profile, surface-mount, no-clamp
connector that accommodates higher I/O counts.
