Abstract: A power supply device for a vehicle, in particular for a utility vehicle such as an electric bus or an electric heavy goods vehicle, wherein the power supply device includes at least one contact head that can be brought in contact with a docking station to establish an electrical connection, and includes at least a first pivot arm that is connected to the at least one contact head, where the at least first pivot arm is connectable to a vehicle so as to be rotatable about a first axis and a second axis that extend at an angle from one another, where the first axis extends parallel to a transverse vehicle axis, and the second axis extends parallel to a longitudinal vehicle axis so as to allow for more flexible movability of the contact head.

Abstract: An electrical contacting apparatus for the current collector of a vehicle, includes at least an electrical first contact body that is coupled via at least a first spring apparatus to at least a first bearing apparatus, wherein the at least first bearing apparatus is connectable to a current collector linkage or to a current collector holder and where the at least first contact body is electrically connectable to the vehicle, where the at least first contact body and the at least first bearing apparatus are electrically insulated from each other such that it becomes possible to dispense with separate insulators for electrically insulating a current collector from its environment.
