Abstract

A device is provided for mechanically and electrically connecting a portable, battery-operated apparatus in order to operate the apparatus and/or to charge its battery. The device includes a receiving area for the apparatus as well as a first coil arrangement, which is disposed on, in or under the receiving area and which is designed for interaction with a second coil arrangement of the apparatus, when the apparatus is disposed in a predefined position on the receiving area. Finally, the device exhibits a first coupling element, which, in interaction with a second coupling element of the apparatus, the apparatus can be moved into the predefined position after being placed on the receiving area. The first coupling element exhibits at least a first component, which is designed for magnetic coupling with a respective second component of the apparatus.
