Abstract: A coupler head of a coupling device for mechanically connecting two units is provided. The coupler head comprises at least one coupler lock to form a mechanical connection with a coupler lock of a counter-coupler head, and an electrical contact coupling for the coupling of at least one electrical line between the coupler head and the counter-coupler head. The coupler head further comprises a base body to which the coupler lock and the electrical contact coupling are mounted, so as to enable the coupler head to be universally applicable for a plurality of applications and in particular for it to be operated as low-maintenance as possible. A coupler head housing accommodates the base body with the at least one coupler lock and electrical contact coupling. The base body further comprises a linkage to which a coupling shaft is articulated so as to be pivotable in a horizontal and/or vertical plane.

Abstract: Described are an optical signal coupling for two vehicles coupled with one another and a conductive coupling which contains such a signal coupling. The signal coupling has a first and a second coupling part each of which is carried by a respective one of the vehicles and between which the optical signals are transmitted. The first coupling part contains a sending device which creates the optical signals to be transmitted, and the second coupling part contains a receiving device which detects the transmitted optical signals.

Abstract: A light conductor coupling has a first and a second coupling part which coupling parts are couplable with one another and in each of which a light conducting element is held. At least one of the light conducting elements is elastically biased so that the two light conducting elements are pressed against one another with their end surfaces when the coupling parts are coupled with one another, to allow the transmission of light from one light conducting element to the other. The end surface of the one light conducting element is spherically concave and the end surface of the other light conducting element is formed spherically convex with the same radius of curvature.
