Abstract
A device (100) for transmitting an electrical current between two elements that are movable relative to each other, by a strip (30) containing carbon, which extends in a longitudinal direction and is designed to rub against one of the elements so as to transmit an electrical current, the transmission device including: a strip holder (6), and bearing structure (10) designed to exert force on the strip (30), which urges same against the holder (6), the force being transverse relative to the longitudinal direction, wherein the bearing structure (10) and/or the holder (6) are shaped so as to occupy only a portion of the length of the strip (30) in the longitudinal direction.
