    • PROBLEM TO BE SOLVED: To provide a small-diameter multi-conductor cable excellent in twisting resistance and flex resistance.SOLUTION: In a multi-conductor cable, a plurality of wire units 12, each of which includes a plurality of twisted small-diameter wires 11, are bundled to form a wire assembly 14, a shield layer 15 including braided strand conductors 15a is disposed on the outer periphery of the wire assembly, the outside of the shield layer is covered with a sheath 16 made of a resin. The strand conductors 15a of the braided shield layer 15 comprise a silver-plated copper alloy wire which has a strand diameter of 0.04-0.15 mm, a conductor elongation of 0.8% or more, and a thickness of the silver plating of 0.6 μm or more. The strand diameter may be in the range of 0.08-0.15 mm, and further, the thickness of the sheath 16 is in the range of 0.6-1.0 mm and a gap G between the inner face of the sheath and the wire assembly is preferably in the range of 0.1-0.5 mm.
    • 要解决的问题:提供耐扭曲和抗弯曲性优异的小直径多导体电缆。解决方案:在多导体电缆中,多个线单元12,每个线单元12包括多个扭转的小直径 电线11被捆扎以形成电线组件14,包括编织线导体15a的屏蔽层15设置在电线组件的外周上,屏蔽层的外部被由树脂制成的护套16覆盖。 编织屏蔽层15的绞线导体15a包括一个镀银铜合金线,其股线直径为0.04-0.15mm,导体伸长率为0.8%以上,银镀层厚度为0.6μm以上 。 绞线直径可以在0.08-0.15mm的范围内,而且护套16的厚度在0.6-1.0mm的范围内,护套的内表面和线组件之间的间隙G优选为 范围在0.1-0.5毫米。
