  • Patent number: 10574012
    Abstract: A rotatable connector device includes a stationary member, a rotatable member rotatably attached thereto, and a flat cable housed in an annular space between the stationary and rotatable members. One end of the flat cable is connected to a stationary-side connector fixed to the stationary member, and another end of the flat cable is connected to a rotating-side connector fixed to the rotatable member. The flat cable includes a folded-back portion bent and folded back at a middle section in a longitudinal direction thereof. The flat cable includes a predetermined number of conductor/conductors each comprising a copper alloy and wound up or rewound with bending kept at the folded-back portion. Each conductor satisfies Y?14.175X2?249.35X+1406.9 for a bending radius of 4 to 8 mm, where X denotes bending radius, and Y denotes 0.2% yield stress, and has an electrical conductivity of 50% IACS or greater.

  • Patent number: 9394588
    Abstract: A terminal includes a connector portion electrically connectable to an external terminal, a tubular crimp portion formed integrally or separate from the connector portion and crimps with a wire, and a transition portion coupling the two. The tubular crimp portion of a copper or copper alloy metal base material or a metal member having the same is a tubular member closed on transition portion side and reduces in diameter towards the transition portion side such that a conductor-end portion of the electric wire is un-exposed. The tubular crimp portion has a belt-shaped weld portion along a longitudinal direction of the tubular crimp portion. A circumferential direction of the tubular crimp portion matches the RD-direction of the base material. A sum of area ratios R1, R2 and R3 in a rolling plane of the base material, of Cube-, RDW-, and Goss-oriented crystal grains, respectively, is greater than or equal to 15%.
