  • Electrically insulating lead-through assembly with electrocorrosion protection
    Patent number: 6025578
    Abstract: An electrically insulating lead-through assembly through which an electrical conductor passes through a metal casing. The metal casing belongs to an exhaust gas system of an internal combustion engine, in particular to an electrically heatable catalytic converter. A metallic sleeve which is welded to the casing defines the lead-through opening through which the conductor extends. The lead-through assembly is protected against electrocorrosion by a sacrificial electrode which is disposed on the sleeve, on the casing in the vicinity of the sleeve, or on a housing covering the lead-through. Alternatively, a ground connector may be connected in the vicinity of the lead-through.
