ROTATABLE CONNECTOR DEVICE

摘要

An SRC includes a stator; a rotator rotatably attached to the stator; and a stack-type cable accommodated in an annular accommodation space defined by the stator and the rotator. The stack-type cable includes a transmission path FC including a pair of transmission path conductors and laminate sheets covering the pair of transmission path conductors and also includes a dummy FC that is provided on a front surface of the transmission path FC and is formed of laminate sheets not including a flat rectangular conductor, the transmission path FC and the dummy FC being stacked on each other; the stack-type cable further includes a grease that causes the transmission path FC and the dummy FC stacked on each other to adhere to each other; and a width-direction interval between the pair of transmission path conductors is set to smaller than, or equivalent to, a conductor width of each transmission path conductor.

1. A rotatable connector device, comprising:
a fixed-side member; a rotatable-side member rotatably attached to the fixed-side member; and a flat cable accommodated in an annular accommodation space defined by the fixed-side member and the rotatable-side member; wherein: the flat cable includes a signal flat cable including a pair of signal conductors and a band-like resin covering the pair of signal conductors and also includes a dummy flat cable that is provided on at least one of a front surface and a rear surface of the signal flat cable and is formed of a band-like resin not including a conductor, the signal flat cable and the dummy flat cable being stacked on each other; the flat cable further includes adhering means that causes the signal flat cable and the dummy flat cable stacked on each other to adhere to each other; and a conductor interval between the pair of signal conductors is set to smaller than, or equivalent to, a conductor width of each of the pair of signal conductors.
