Title:
SHIELD WIRE, AND WIRE HARNESS
Document Type and Number:
Japanese Patent JP2022025299
Kind Code:
A
Abstract:
To provide a shield wire capable of preventing a wire from generating collapse while improving wire-arranging property by suppressing a bending R, and a wire harness.SOLUTION: A shield wire 1 includes: one cylindrical metal pipe 10; and a wire 20 having a conductor 21, and an insulator 22 around a conductor outer periphery provided in a cylinder of the one metal pipe 10 by only one. A wire conductor outer diameter a' after thermal expansion at 25°C is a'=a+αa×a×Δt when a wire conductor outer diameter at 25°C is a, a linear expansion coefficient of a conductor material is αa, and a temperature difference between 25°C and a maximum temperature exposed to an environment where the wire 20 is used is Δt. An insulator thickness b' after expansion at 25°C is b'=b+αb×b×Δt when an insulator thickness at 25°C is b, and a linear expansion coefficient of an insulator material is αb. An inner diameter c of the one metal pipe 10 satisfies c≥a'+2b'.SELECTED DRAWING: Figure 2
