ABSTRACT:
The present invention is directed to a device which includes a cylindrical support provided with coaxial conducting rings, and a brush support carrying brushes respectively in sliding contact with the rings. An extension of this support constitutes another support for a set of longitudinal conducting tracks linked respectively to the brushes. The brushes in sliding contact with the tracks are carried by a brush support which is able to move translationally on the support. There may, therefore, be relative translational and rotational movements between a cable, the conductors of which are linked to the rings, and a cable, the conductors of which are linked to the brushes, while still providing electrical continuity between them. The device of the present invention is useful in supplying current to the blades of the tail rotor of a helicopter from a structure able to move translationally.
