Title:
TRANSMISSION CABLE
Document Type and Number:
Japanese Patent JP2009021978
Kind Code:
A
Abstract:

To provide a transmission cable that has three signal lines, and in which there is less unwanted radiation noise.

In a section that is perpendicular to the longitudinal direction of a differential transmission cable 2, the distance between any two signal lines of three signal lines 2a, 2b, 2c is equal to a predetermined value. A differential transmission cable 2A is twisted in its longitudinal direction. A differential transmission cable 2B further includes a dielectric core line 2d, and the signal lines 2a, 2b, 2c are formed on the surface of the dielectric core line 2d. In a differential transmission cable 2C, the signal lines 2a, 2b, 2c are formed in a helix in the longitudinal direction of the dielectric core line 2d.
