Japanese Patent JP2020024868
Kind Code:
A
Abstract:
To provide a coaxial cable having excellent flexibility, with degradation of electrical properties being suppressed.SOLUTION: A coaxial cable 1 comprises a central conductor 10, an electrical insulator 20 covering the circumference of the central conductor 10, and a shield conductor 30 made of conductive strand 31 spiral covering the circumference of the electrical insulator 20. The electrical insulator 20 having a gear shape comprises an annular part 21 surrounding the circumference of the central conductor 10 and 8 protrusions 22 protruding from the annular part 21 to the outside in the radial direction. The diameter dof the conductor strand 31 has a size of 9% or more and 21% or less of the tooth tip diameter d of the electrical insulator 20.SELECTED DRAWING: Figure 1
