Abstract
Official abstract text for this publication.
A bus bar electric wire includes a flat conductor which is formed of aluminum and inevitable impurities, and which has a cross-section of a substantially rectangular shape. An area of the cross-section is 15 mm2 or more and 240 mm2 or less. The flat conductor includes a bent portion having a predetermined bending R in a plane direction of the flat conductor, and a conductor part that is an outermost side of a bend in the bent portion has a plate width being set within a range satisfying uniform bending of the conductor part.
First claim
Opening claim text (preview).
What is claimed is: 1. A bus bar electric wire comprising: a flat conductor which is formed of aluminum and inevitable impurities, and which has a cross-section of a substantially rectangular shape, and an area of the cross-section being 15 mm 2 or more and 240 mm 2 or less, wherein the flat conductor includes a bent portion having a predetermined bending R in a plane direction of the flat conductor, and a conductor part that is an outermost side of a bend in the bent portion has a plate width being set within a range satisfying uniform bending of the conductor part, and wherein when the flat conductor has a maximum elongation of 38.2%, a plate width of w mm, and a bending radius of R mm, 38.2% >w/(2R +w) is satisfied. 2. The bus bar electric wire according to claim 1 , further comprising: an insulating cover that covers an outer periphery of the flat conductor, wherein the insulating cover is formed of a material and a thickness such that an outer side of a bend of the bent portion would not break. 3. The bus bar electric wire according to claim 2 , wherein the insulating cover is formed of a material having elongation of 35% or more. 4. The bus bar electric wire according to claim 2 , wherein when a length of the flat conductor is I mm, an elastic region of a metal forming the flat conductor is ε E %, a longitudinal elastic modulus of the metal is EN/mm 2 , a plate width of the flat conductor is b mm, a plate thickness of the flat conductor is h mm, and an equal load applied to the flat conductor is wN, I ≤√{square root over (2×((ε E ×E )×( b×h 2 /6))/ w )} [Formula 1] the Formula 1 is satisfied.
