ABSTRACT:
The invention is a flexible interconnection which is used to transmit electrical signals across a rotatable mechanical coupling in a mechanical system. The mechanical system includes a first member defining a first surface and a second member defining a second surface. The first and second members are coupled for rotation in a plane of rotation about an axis. The first and second surfaces are juxtaposed. The interconnection includes a flexible cable which is fixedly attached to a first point on the first surface and a second point on the second surface. A "U" shaped portion of cable is formed between the two points of attachment. The "U" shaped portion has a first longitudinal portion which is substantially parallel to the plane of rotation, a second longitudinal portion which is substantially parallel to the plane of rotation, and a curved portion connecting the first and second longitudinal portions. The curved portion defines a central line of the bend which is substantially parallel to the plane of rotation. The "U" shaped portion is disposed between the first and second members such that the central line of the bend is located a distance r from the axis, where r is substantially equal to 1.092 times distance d. This allows smooth rotation of the interconnection.
