Abstract
The present invention is full-rotational freedom conductor assembly for conducting electricity between a pair of coaxial electrically conductive members. The conductive members are provided with complementary, planar tracks and are relatively rotatable about a common axis thereof. The invention includes a pair or pairs of opposing coupler halves having a planetary axis, with track-adapted profiles. The pairs of coupler halves are rotatably confined between the tracks enabling electrical contact between the tracks of the conductive members. The invention further includes a force source located at least partially between the coupler halves. The force source applies force to each of the coupling halves in a direction substantially parallel to the second common axis. The force is applied to the pairs of coupler halves in a manner that enables the coupler halves to be flexibly retained between the tracks.
