Title:
COMPOSITE ELECTRIC WIRE AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2022171278
Kind Code:
A
Abstract:
To obtain a composite electric wire rich in electric conductivity and large in plasticity.SOLUTION: A composite electric wire having an outer diameter of approximately 500 μm includes: a coated layer 3 provided to surround a central core wire 2; a conductive layer 4 arranged around the coated layer 3; and an insulating coating layer 5 provided around the conductive layer 4. The core wire 2 is formed by twisting four middle wires 2a-2d; each of the middle wires 2a-2d is formed by twisting a single wire consisting of, for example, 48 aramid fibers; the diameter of the single wire is, for example, 12 μm; the diameter of the core wire 2 is approximately 200 μm; 12 copper wires 4a having a diameter of 80 μm are spirally and closely wound around the core wire 2 as the conductive layer 4; the periphery of the copper wire 4a is shaped into a circle by tightening; and the periphery of the copper wire 4a is covered with a tin layer 4b formed of a low melting metal and having a thickness of several μm.SELECTED DRAWING: Figure 1
