Abstract

Abstract A fine enamel insulated wire is joined to a heavier diameter wire by a method including the boriding and plating of the heavier wire, wrapping the fine wire about the heavier wire, and heating the heavier wire sufficiently to burn away the insulation and fuse the two wires together.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 80 words
A method of joining at least two wires, wherein one of the wires is of copper and has a thermally decomposable insulation coating, and the other wire is borided nickel or nickel and has a silver coating, comprising wrapping the one wire around the other wire, heating the other wire to burn away said insulation coating, melting said silver and causing the silver to fuse With the copper and provide an electrically conductive brazed joint between the copper and nickel.
Claim 2
Independent Claim 80 words
A method of joining at least two wires, wherein one of the wires is of copper and has a thermally decomposable insulation coating, and the other wire is borided nickel or nickel and has a silver coating, comprising wrapping the one wire around the other wire, heating the other wire to burn away said insulation coating, melting said silver and causing the silver to fuse With the copper and provide an electrically conductive brazed joint between the copper and nickel.
Claim 3
Dependent Claim 22 words
A method of joining wires according to claim 1, wherein said heating is accomplished by passing electric current through said other wire.
Claim 4
Independent Claim 22 words
A method of joining wires according to claims 1 and 2 wherein said heating is carried out in an atmosphere containing oxygen.
Claim 5
Independent Claim 102 words
A method of joining at least two wires wherein one of the wires is of copper and has a thermally decomposable insulation coating, and the other wire is of nickel comprising boriding the nickel wire, silver plating the borided nickel wire, wrapping the copper wire around the last named wire, heating the last named wire bypassing an electrical current therethrough in the region of the wrapped copper wire to burn away the said insulation coating, melting the silver and causing the silver to fuse with the copper and provide an electrically conductive brazed joint between the copper wire and the nickel wire.
Claim 6
Independent Claim 102 words
A method of joining at least two wires wherein one of the wires is of copper and has a thermally decomposable insulation coating, and the other wire is of nickel comprising boriding the nickel wire, silver plating the borided nickel wire, wrapping the copper wire around the last named wire, heating the last named wire bypassing an electrical current therethrough in the region of the wrapped copper wire to burn away the said insulation coating, melting the silver and causing the silver to fuse with the copper and provide an electrically conductive brazed joint between the copper wire and the nickel wire.
