Abstract: Potential equalisation arrangement for an electric motor has a rotating hollow shaft and a grounding device for reducing electrical potential differences between the hollow shaft and a housing. The grounding device has a shaft grounding ring, which has a support body and an electrically conductive grounding element connected thereto, having a flexible grounding lip for contacting a conductive counter face.

Abstract: An electrical contact element having a frame clamp comprises a frame with a stationary thread, a clamping shoe and a clamping screw engaging in the stationary thread and being supported on the clamping shoe. A plastic holder with a cavity having two insertion openings arranged on opposite walls of the cavity is provided for inserting two electrical conductors to be contacted with one another, in which the frame clamp is arranged. The frame clamp is captively fixed in the cavity of the plastic holder by means of a latching. The frame clamp is mounted in a floating manner in the cavity of the plastic holder in the direction of at least one axis, which is oriented orthogonally to an insertion direction of the electrical contacts into the insertion openings.

Abstract: The invention relates to an electrical conductor for the conduction of electrical current through an opening of a housing wall, wherein the electrical conductor is enclosed, at least in a first sealing segment by a sealing body made from an elastic material. The electrical conductor can be inserted with the sealing body into an opening of a housing wall for sealing between sealing body and housing wall. The electrical conductor has a materially bonded connection to the sealing body, and a fastening part is provided on the conductor and has an axial through-opening through which the electrical conductor is inserted, wherein the fastening part extends radially, starting from the axial through-opening, in a first axial segment which has the maximum radial extension of the fastening part perpendicular to the axial through-opening.

Abstract: The invention relates to an electrical conductor for conducting electric current through a housing part, wherein the electrical conductor is enclosed on a first sealing section by a sealing body made of an elastic material, wherein the electrical conductor and the sealing body have an integrally-bonded connection. The electrical conductor has, at least in the first sealing section, an outer contour which is rounded in cross-section. The invention further relates to a method for producing an electrical conductor with a sealing body, which is connected by integral bonding and is made of an elastic material.

Abstract: A shaft earthing ring for establishing an electrical potential connection between a rotating shaft and a housing of an electric motor comprises an electrically conductive earthing element which has a contact portion that contacts the shaft, and a metal support body fixed to the housing. The metal support body has at least one ventilation opening which allows ventilation of a housing interior while bypassing the earthing element.

Abstract: An oil separation device for the crankcase ventilation of an internal combustion engine comprises at least one oil separator with a gas inlet pipe, a gap-determining element, wherein an annular gap is formed or formable between the gap-determining element and an outlet end of the gas inlet pipe, and a baffle wall which is arranged in the flow direction behind the gap. The oil separation device has a driven actuator for adjusting the gap-determining element relative to the gas inlet pipe.
