Supporting pin for an electrically heatable honeycomb body

摘要

A supporting pin for supporting an electrically heatable honeycomb body on a first honeycomb body includes a first end region, a second end region, an intermediate region, a core made of electrically non-conductive ceramic material and a metalized surface on at least one end region. The intermediate region is electrically non-conductive and has a length of at least 3 mm, preferably 5 to 15 mm. The supporting pin is particularly suitable for stabilizing electrically heatable honeycomb bodies in exhaust gas treatment systems for internal combustion engines, particularly for motor vehicles. When higher electrical voltages, such as 48 V, are used for electrically heatable honeycomb bodies, good electrical isolation is also assured in exhaust gas systems carrying soot particles with simultaneous safe support and suppression of vibrations.
