Title:
自己融着絶縁電線、その製造方法及びコイル
Document Type and Number:
Japanese Patent JP7166769
Kind Code:
B2
Abstract:
To provide an insulation wire and a coil for coil wound wire mainly used in an oil mounted on a DC-DC converter for automobile, hardly generating pinhole, crack or the like in an insulation layer, capable of maintaining insulation pressure resistance even after winding the coil, and having self-fusion performance.SOLUTION: The above describe problem is solved by arranging to have a center conductor 1, and an insulation layer 2a by lap winding an insulation resin tape 2 having a fusion layer 2 on a single surface in an outer periphery of the center conductor 1, in which the fusion layer 2b is an outermost layer. The fusion layer 2b is manufactured by coating formation of a fusion coating consisting of a resin composition mainly containing a thermoplastic resin composition or a thermoplastic resin, the insulation resin tapes are temporarily adhered while maintaining thermoplasticity at a specified temperature, a crosslinking reaction occurs at the specified temperature, and self fusion insulation wires are adhered each other.SELECTED DRAWING: Figure 1
