Title:
SQUARE CROSS SECTION MULTICORE INSULATED WIRE, AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2023007365
Kind Code:
A
Abstract:
To provide a square cross section multicore insulated wire of construction having a constitution excellent in insulation property, capable of applying to a coil in a non-contact charger, and combining flexibility and shape stability.SOLUTION: A square cross section multicore insulated wire 1 has a cluster of wires 2 in which an insulating layer 2b is formed on an outer periphery of a conductor 2a, and has a composite twist structure formed of a first stranded wire 21, a second stranded wire 22, a third stranded wire 23 and a fourth stranded wire 24, an insulating fiber thread 3 is wound around an outer periphery, and the cross section is formed into a rectangular shape, and a winding direction of the fiber thread 3 is the opposite direction of the twist direction of the outermost twisted wire in the cluster of wires 2.SELECTED DRAWING: Figure 1
