Abstract

A current feed-through for an electrically heatable catalytic converter, wherein the catalytic converter has in the interior thereof at least one electrical conductor, which is electrically contactable by the current feed-through, having a central electrically conductive element, which is guided from the interior of the catalytic converter through the outer housing wall thereof, having an electrical insulation layer, which surrounds the electrically conductive element on its radial outer face, and having a metallic sleeve, in which the electrically conductive element and the electrical insulation layer is received, wherein at the current feed-through or directly adjacently to the current feed-through there is arranged a device for reducing the heat conduction from the interior of the catalytic converter along the current feed-through to a contact face arranged outside the catalytic converter.
