Abstract

A system for conductively charging a motor vehicle includes a charging device and a receiving device. The charging device has an electrical contacting unit and a lifting device operable for axially moving the contacting unit between retracted and extended positions. The receiving device has a receiving chamber for receiving the contacting unit inserted therein when the contacting unit is moved to an extended position. The contacting unit has a cylindrical or truncated cone body and includes an electrical contact ring extending around a lateral surface of the body of the contacting unit. The receiving device includes a radially position-able electrical contact element along the receiving chamber. When the contact element is in one radial position while the contacting unit is inserted into the receiving chamber the contact element electrically contacts the contact ring and mechanically fixes the contacting unit to the receiving device inside the receiving chamber.
