Abstract: A connection device for electrically connecting a plurality of first electrical components to a second electrical component and for arrangement on a first housing of the second component. In the interior at least one first and one second potential connection are arranged. The connection device includes a connection strip, which on a first side has a plurality of electrical plug-in connection units for respective electrical connection of one of the first components by a respective plug-in connection and a second opposite side relative to a first direction, for arrangement on a first component, a contacting unit which has a carrier for arrangement on a through opening of the first housing and at least one contact pair arranged on the carrier for electrically contacting the first and second potential connection.

Abstract: A vibration damper with at least two absorbers, each having at least one spoke spring, enables efficient damping of the frequency response of a crankshaft. The absorbers preferably have different natural frequencies that are adapted to the frequency response of the crankshaft. The absorbers exhibit a frequency response, which is not or only insignificantly dependent on aging of the spoke springs and on the ambient temperature. The corresponding vibration dampers can be easily designed and mounted.
