US 12,640,286 B2 · Method of forming cable by opening slit-tape isolator and inserting twisted pairs

Abstract

A dielectric isolator for a twisted pair cable includes a body formed as an elongate strip with a top surface, bottom surface, a first side edge and a second side edge. A first slot is formed in the first side edge and extends at least half way toward the center of the isolator. A second slot is formed in the second side edge and extends at least half way toward the center of the isolator. During cable manufacturing, first and second wedges open the first and second slots. First and second twisted pairs are inserted into the first and second opened slots, respectively. Third and fourth twisted pairs reside at the top and bottom surface, respectively. The isolator has the cost and reel storage savings of a flat separator tape, while simultaneously providing the internal crosstalk performance of the isolator.

Dependent claims

A method of forming a twisted pair cable comprising:

providing an isolator including:
a body formed as an elongate strip with a top surface and a bottom surface, with a distance between the top and bottom surfaces defining a thickness of the body;
a first side edge and a second side edge formed on the body, with a distance between the first and second side edges defining a width of the body;
and
a first slot formed in the first side edge and extending into the body in a direction of the width of the body;
feeding the isolator to a cable assembly area;
opening the first slot of the isolator in the cable assembly area;
placing a first twisted pair into the opened first slot of the isolator;
placing a second twisted pair adjacent to the top surface of the isolator;
placing a third twisted pair adjacent to the bottom surface of the isolator;
and
covering the isolator and the first, second and third twisted pairs with a jacket.
