Abstract

A connection unit for connecting an electrical supply line to an exhaust gas heater of an exhaust system of an internal combustion engine includes an electrically conductive connection element. The connection element has a heater connection region in a first end region and a supply line connection region in a second end region. A carrier has a receiving opening, wherein the connection element is arranged and has a support region. A first insulating element is arranged in the opening and surrounds the support region. A second insulating element is arranged on a first end face of the carrier. The connection element is supported with respect to the first end face via the second insulating element. A third insulating element is arranged on a second end face of the carrier. The connection element is supported with respect to this second end face via the third insulating element.
