耐屈曲電線及びワイヤハーネス
Document Type and Number:
Japanese Patent JP6775283
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a bending resistant electric wire in which deterioration in bending resistance can be suppressed while suppressing the collapse and flatness of the shape in a conductor part.SOLUTION: Provided is a bending resistant electric wire 1 using a composite twisted wire 12 formed by further normally twisting a plurality of aggregated twisted wires 11 formed by lower twisting of twisting a plurality of conductive elemental wires 11c as a conductor part 10, the conductor 10 is made of: the innermost layer twisted wire 11a as the assembled wire 11 located on the most cross-sectional center side of the conductor part 10; and a circumferential twisted wire 11b as an assembled twisted wire 11 provided superimposingly to a plurality of the layers to the circumference of the innermost layer twisted wire 11a, in the circumferential twisted wire 11b, the lower twisting direction and normal twisting direction of the respective assembled twisted wires 11 is reverse, also, in the adjacent layers, the normal twisting direction is reverse, and the number of the assembled twisted wires 11 is higher than that of a plurality of the elemental wires 11c composing the respective assembled twisted wires 11.SELECTED DRAWING: Figure 2
