Abstract
An insulated electric including a conductor, an insulator covering a periphery of the conductor, and an outer diameter of 0.1 mm or less, wherein the insulator is made of a resin composition mainly composed of fluororesin and has a thickness 10 μm or more and 30 μm or less, and wherein a crush strength measured by a method according to UL 2556 standard is 15 N/50 mm or more.
Claims6
An insulated electric wire, comprising:
- a conductor;
- an insulator covering a periphery of the conductor;
- and
- an outer diameter of 0.1 mm or less,
- wherein the insulator comprises a resin composition mainly composed of fluororesin and a thickness 10 μm or more and 30 μm or less, and
- wherein a crush strength measured by a method according to UL 2556 standard is 15 N/50 mm or more.
A method for manufacturing an insulated electric wire comprising a conductor, an insulator covering a periphery of the conductor, and an outer diameter of 0.1 mm or less, the method comprising:
- providing the insulator comprising a resin composition mainly composed of fluororesin by extrusion molding around the conductor,
- wherein the extrusion molding is performed with a molding temperature being +5° C. or more and +25° C. or less relative to a melting point of the fluororesin and a preheat temperature of the conductor being equal to or above the melting point of the fluororesins, to provide the insulator a thickness of 10 μm or more and 30 μm or less.
