Application No. 08/443,217
a coaxial cable, includes an insulated conductor surrounded by
an electromagnetic shield formed using a foil wrapper and
braided wire. Unfortunately, such a conventional cable
affords incomplete shielding. Furthermore, bending or other
moving spreads the wire braid and foil wrapper, thereby
degrading the integrity of the shielding.
The appellants' shielded cable includes insulated
conductors; a flexible, seamless covering surrounding the
conductors; and an outermost jacket surrounding the covering.
In turn, the flexible, seamless covering comprises a
conductive layer bonded to an insulating layer, where the
conductive layer forms a seamless, electromagnetic shield.
Because the conductive layer is seamless and has a thickness
much less than the thickness of the insulating layer, the
inventive shielded cable purportedly provides enhanced
shielding while remaining flexible.
Claim 1, which is representative for our purposes,
follows:
1. A flexible shielded bulk cable, comprising:
