Abstract
Aspects of the present invention relate to reinforced electric wires, particularly reinforced electric wires as used in holiday lighting such as Christmas light strings. In some embodiments, the reinforced electric wire can comprise a conductor, a reinforcing string or one or more reinforcing threads, and an insulator jacket. In some embodiments, the conductor comprises a plurality of conductor strands and one or more reinforcing strands arranged within an insulator jacket. Methods of making wires in accordance with various embodiments are also provided herein.
Claims20
A reinforced electric wire for use in holiday lighting, the wire comprising:
- an insulator jacket defining an outer perimeter of the wire;
- a conductor disposed in the insulator jacket proximate a first portion of the outer perimeter;
- and
- a reinforcing string, disposed proximate a second portion of the outer perimeter opposite the first portion, and partially encircling the conductor.
A system for manufacturing a reinforced electric wire for use in holiday lighting, the system comprising:
- an insulation material feeder;
- a heater configured to heat an insulation material fed through the insulation material feeder;
- and
- a generally conically shaped extrusion die configured to produce a hollow channel in the heated insulation material drawn therearound.
An artificial tree comprising:
- a first trunk section including:
- a first plurality of branches connected to the first trunk section;
- a light set distributed on a first branch and a second branch of the first plurality of branches, the light set including a plurality of lamp assemblies;
- a plurality of reinforced wires electrically connecting the plurality of lamp assemblies, the plurality of reinforced wires comprising:
- a first wire comprising:
- a first insulator jacket defining an outer perimeter of the first wire;
- a first conductor disposed in the first insulator jacket proximate a first portion of the outer perimeter;
- and
- a first reinforcing string, disposed proximate a second portion of the outer perimeter opposite the first portion, and partially encircling the first conductor;
- and
- a second wire comprising:
- a second insulator jacket defining an outer perimeter of the second wire;
- a second conductor disposed in the second insulator jacket proximate a first portion of the outer perimeter;
- and
- a second reinforcing string, disposed proximate a second portion of the outer perimeter opposite the first portion, and partially encircling the second conductor,
- wherein a first lamp assembly of the plurality of lamp assemblies is electrically connected to the first wire and the second wire.
