Abstract
Pliable high-strength conductors for use in electronic instruments involving frequent movements, such as robots. They comprise a core layer of austenitic stainless steel and a covering layer of copper, or its alloy. Higher resistance to flexing fatigue is ensured by the addition of stainless steel as a core. An austenitic stainless steel wire having a specific diameter is employed and the percentage of sectional area of the covering layer to the total sectional area is specified.
