Abstract

An electrical connection for an electrical component or electrically heatable honeycomb body, in an exhaust system of an internal combustion engine includes an electrical conductor passing through a metallic jacket of the exhaust system, a bushing and an insulating layer and having an outer connection section with circular cross section. The connection section has a contact surface for connection to a supply line connection piece. The bushing and/or electrical conductor near the bushing can absorb torques up to 3.6, 4.5 or 7 Nm per cm2 of contact surface acting on the connection section and/or an internal or external thread in circumferential direction, by shaping the electrical conductor near the bushing or using structures and/or changes to the cross section or a form-locking construction of the electrical conductor and the bushing. Damage to electrical exhaust components due to external torques, disassembly and maintenance can thus be avoided.
