Abstract: A housing for a module pole connection providing touch protection for the module pole connection. The housing has a module pole busbar with a contact region and is connected in a connecting direction to a module connector and is electrically contacted via the contact region. The housing is electrically insulating, and receives the module pole busbar, and has a first housing wall which has a recess region with at least one recess for exposing at least part of the contact region of the module pole busbar when the module pole busbar is received as intended in the housing. The first housing wall has a recess edge region surrounding the recess region in a radial direction. The first housing wall has an electrically insulating insulation ring radially within the recess region, which is connected to the recess edge region via at least one insulation web.

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.
