Abstract

Reinforced electric wires, particularly reinforced electric wires as used in holiday lighting such as Christmas light strings are disclosed. In some embodiments, the reinforced electric wire has a conductor, a reinforcing string or one or more reinforcing threads, and an insulator jacket. In some embodiments, the conductor has a single conductor strand. In some embodiments, the conductor has a plurality of conductor strands. In some embodiments, the wire has an insulator jacket having a plurality of channels therein, where a conductor is passed through the center channel, and reinforcing threads are passed through the other channels.

First claim

What is claimed is:

1. A reinforced electric wire for use in holiday lighting, the wire comprising:
a plurality of conductor strands parallel to the length of the wire;
a plurality of reinforcing threads, each reinforcing thread of the plurality of reinforcing threads being disposed in a respective gap of a plurality of gaps, the respective gaps each disposed between at least two conductors of the plurality of conductors; and
an insulator jacket covering the conductor strands and the reinforcing threads and in contact with a subset of the plurality of conductor strands and a subset of the reinforcing threads.

2. The reinforced electric wire of claim 1 , wherein the reinforcing threads are not twisted with the conductor strands.

3. The reinforced electric wire of claim 1 , wherein the conductor strands are not substantially wrapped around the reinforcing threads, and the reinforcing threads are not substantially wrapped around the conductor strands.

4. The reinforced electric wire of claim 1 , wherein the reinforcing threads are made of a material selected from the group consisting of: nylon, polyester, polypropylene, rayon, Poly-paraphenylene terephthalamide, or mixtures thereof.

5. The reinforced electric wire of claim 1 , wherein the reinforcing threads comprise a conductive metal having a higher resistivity than the conductor.

6. The reinforced electric wire of claim 1 , wherein the insulator jacket is made from a material comprising a plastic.

7. The reinforced electric wire of claim 1 , wherein:
the reinforcing threads comprises a nylon yarn, the plurality of conductor strands comprise a portion of an AWG #22 stranded copper wire, and
the insulator jacket is made of a material comprising PVC.

8. A reinforced electric wire for use in holiday lighting, the wire comprising:
a plurality of outer conductor strands, each conductor strand of the plurality of outer conductor strands being oriented around an outside perimeter of the wire;
a plurality of inner conductor strands, each conductor strand of the plurality of inner conductor strands disposed nearer a central axis of the wire than each conductor strand of the plurality of outer conductor strands;
a reinforcing string comprising a plurality of reinforcing threads, the reinforcing string being disposed within a gap between at least two outer conductor strands; and
an insulator jacket covering the conductor strands and the reinforcing string, the insulator jacket contacting the outer conductor strands and the reinforcing string.
