PROBLEM TO BE SOLVED: To realize both low resistance and low electrostatic capacity to improve flexibility. SOLUTION: Although a spacer is required to be interposed to realize low resistance and low electrostatic capacity, which, however, sacrifices noise resistance property and flexibility. To cope with this, core wires are arranged to have a star-quad structure, which has a bellows-like structure in which large spacers 1 and small spacers 2 are arranged with a constant interval. By this, a cable absorbs distortion at the time of bending by being twisted, thereby suppressing friction between core wires, resulting in obtaining flexibility. Further, since symmetric property of the star-quad structure is maintained even if the cable is bent, a noise canceling capability can be obtained. COPYRIGHT: (C)2013,JPO&INPIT |
