Abstract

Official abstract text for this publication.

A covered electrical wire comprises a conductor and an insulating covering layer provided outside the conductor, the conductor being a stranded wire composed of a strand of a plurality of copper alloy wires: composed of a copper alloy containing Fe in an amount of 0.2% by mass or more and 1.6% by mass or less, P in an amount of 0.05% by mass or more and 0.4% by mass or less, and Sn in an amount of 0.05% by mass or more and 0.7% by mass or less, with the balance being Cu and impurities, and having a mass ratio of Fe/P of 4.0 or more; and having a wire diameter of 0.5 mm or less.

First claim

The invention claimed is: 1. A covered electrical wire comprising a conductor and an insulating covering layer provided outside the conductor, the conductor being a stranded wire composed of a strand of a plurality of copper alloy wires: composed of a copper alloy consisting of Fe in an amount of 0.2% by mass or more and 1.6% by mass or less, P in an amount of 0.05% by mass or more and 0.4% by mass or less, Sn in an amount of 0.05% by mass or more and 0.7% by mass or less, and C, Si, and Mn in an amount of more than 30 ppm and 150 ppm or less by mass in total, C in an amount of 30 ppm or more, with the balance being Cu and impurities, and having a mass ratio of Fe/P of 4.0 or more; and each copper alloy wire having a wire diameter of 0.5 mm or less. 2. The covered electrical wire according to claim 1 , wherein the copper alloy wire provides an elongation at break of 5% or more. 3. The covered electrical wire according to claim 1 , wherein the copper alloy wire has a conductivity of 60% IACS or more and a tensile strength of 400 MPa or more. 4. The covered electrical wire according to claim 1 , having a terminal fixing force of 45 N or more. 5. The covered electrical wire according to claim 1 , having an impact resistance energy of 3 J/m or more in a state with a terminal attached. 6. The covered electrical wire according to claim 1 , wherein an impact resistance energy of the covered electrical wire is 6 J/m or more. 7. A terminal-equipped electrical wire comprising a covered electrical wire according to claim 1 and a terminal attached to an end of the covered electrical wire.
