Abstract (en)
Rotatable electrical contact connection between two conductors which are rotatable relative to each other, one of said conductors consisting of a contact pin (11) and the other of a contact sleeve (10) arranged concentrically around the contact pin. The internal diameter of the contact sleeve is larger than the external diameter of the contact pin, such that between the pin and the sleeve an annular gap (12) is formed, in which a number of elongated, relatively narrow contact rollers (13), oriented parallel to the longitudinal axis of the pin, are evenly distributed around the periphery of the pin. According to the invention, the contact pin and the contact sleeve are formed with radially outwardly projecting annular elevations (14) and radially inwardly projecting annular elevations (15), respectively, in such a way that the contact rollers (13) are strained in wave form between the pin and the sleeve, thus providing the necessary contact force at the contact points. <MATH>
