Method for making cable jacket with embedded shield

摘要

A method for making a cable jacket that includes the steps of providing at least one shielding tape having a substrate formed of a substrate material, said substrate including at least one conductive segment; inserting the at least one shielding tape between first and second jacket layers of the cable jacket, each of said first and second jacket layers being formed of a jacket material; and co-extruding the at least one shielding tape with the first and second jacket layers, wherein the substrate material of the at least one shielding tape and the jacket material of the first and second jacket layers are the same such that during the co-extrusion step, the substrate and first and second jacket layers bond together into a single layer wherein the at least one conductive segment is embedded in the single layer.

1. A method for making a cable jacket having an annular shape at a cross-section taken orthogonal to a central axis of the cable jacket, the method comprising:
providing a shielding tape comprising a substrate and a plurality of conductive shield segments disposed on the substrate; twisting a pair of wires to form a twisted pair; extruding an inner jacket layer onto an inner surface of the substrate and over the twisted pair; routing a separator through an interior of the inner jacket layer; extruding an outer jacket layer onto an outer surface of the substrate; and heating the substrate through the extruding of the inner and outer jacket layers such that the substrate, the inner jacket layer and the outer jacket layer bond together into a single layer that defines a circumference; wherein each conductive shield segment:
extends only partially around the circumference of the single layer;is longitudinally spaced from each longitudinally adjacent conductive shield segment;is radially spaced from, and overlaps a portion of, each immediately circumferentially adjacent conductive shield segment; andis embedded in at least one of the inner jacket layer and the outer jacket layer.
