SEPARATOR TAPE FOR TWISTED PAIR IN LAN CABLE

摘要

A cable includes a jacket surrounding first and second insulated conductors and a first dielectric tape, wherein the first insulated conductor is twisted with the second insulated conductor with the first dielectric tape residing therebetween to form a first twisted pair. The cable's jacket may also surround additional twisted pairs, which are similarly formed. In alternative or supplemental embodiments of the invention, the first dielectric tape has a hollow core possessing a gas or material with a lower dielectric constant and/or at least a first side of said first dielectric tape facing to said first insulated conductor includes a plurality of ridges and valleys.

主权项

1. A cable comprising:
a first insulated conductor, a first dielectric tape formed as a single unitary structure which does not include multiple pieces attached together or layered, and a second insulated conductor, wherein said first insulated conductor is twisted with said second insulated conductor with said first dielectric tape residing between said first insulated conductor and said second insulated conductor to form a first twisted pair; and a jacket formed around said first twisted pair, wherein said first dielectric tape has a cross sectional shape in a direction perpendicular to the extension length of said first twisted pair, which presents a first recessed portion for seating said first insulated conductor and a second recessed portion for seating said second insulated conductor, and wherein said first dielectric tape has a hollow core possessing a gas or material with a lower dielectric constant than a material used to form said first dielectric tape.
