Electrically insulating gastight feedthrough

摘要

An electrically insulating gas-tight penetration is provided for at least two electrical conductors passing through a metal shell of an exhaust system of an internal combustion engine, in particular a metal shell of an electrically heatable catalytic converter. The shell has a sheath in the region of the penetration and the conductors extend through the sheath. Electromagnetic impulses are avoided by running the conductors coaxially to one another.
