Abstract

A number of coaxially shielded signal conductors are formed into a ribbon cable with two rows of conductors that are offset to form a diagonally packed pattern of signal conductors when several ribbons are stacked together. The individual cables have a conventional outer braid and an intervening dielectric spacer. The outer braid forms the ground conductor as is conventional. In addition, a ground wire is spiraled around the outer braid of each cable. A braided web mesh is located between the two rows of conductors and makes electrical contact with the braids and the spiraled ground wire of the cables. The mesh forms part of a common ground structure. As seen in section, the braided web mesh is curved over the cables of the lower row and under the cables of the upper row.

Flat Ribbon Cable With Two Offset Rows of Shielded Conductors Adapted to Plug Directly Into a Receiving Connector

      A number of coaxially shielded signal conductors are formed
into a ribbon cable with two rows of conductors that are offset to
form a diagonally packed pattern of signal conductors when several
ribbons are stacked together.  The individual cables have a
conventional outer braid and an intervening dielectric spacer.  The
outer braid forms the ground conductor as is conventional.  In
addition, a ground wire is spiraled around the outer braid of each
cable.  A braided web mesh is located between the two rows of
conductors and makes electrical contact with the braids and the
spiraled ground wire of the cables.  The mesh forms part of a common
ground structure.  As seen in section, the braided web mesh is curved
over the cables of the lower row and under the cables of the upper
row.  This structure is located in a supporting ribbon of dielectric
material.

      The ends of the cables are stripped to expose the conductors,
which are initially circular in section.  The exposed conductors are
metal cladded to form a rectangular contact section.  This sectional
shape makes the ends of the conductor stronger and it duplicates the
shape of a separate connector that is otherwise attached to a
conductor.  The reshaped conductors are plugged in directly to a
receiver connector structure.
