A catalyst body for an electrically heated catalyst has an electrical contacting assembly, which is arranged on the catalyst body and comprises an electrical conductor embedded in the catalyst body and extending in a longitudinal direction of the catalyst body and at least up to one end face of the catalyst body.
First claim
Opening claim text (preview).
The invention claimed is: 1. A catalyst body for an electrically heated catalyst comprising: at least one electrical contacting assembly comprising an electrical conductor embedded in the catalyst body and extending in a longitudinal direction of the catalyst body and at least up to one end face of the catalyst body, and wherein the electrical conductor runs along a shell surface of the catalyst body or with a distance of less than 10 mm to the shell surface. 2. The catalyst body of claim 1 wherein the electrical conductor protrudes beyond at least one end face of the catalyst body. 3. The catalyst body of claim 1 wherein at least one groove extends in the longitudinal direction in the catalyst body, wherein the electrical conductor is arranged at least partly in the at least one groove. 4. The catalyst body of claim 3 wherein the at least one electrical contacting assembly comprises a surface electrode, wherein the surface electrode at least partly covers the at least one groove. 5. The catalyst body of claim 3 wherein the electrical conductor is adhered in the at least one groove. 6. The catalyst body of claim 1 wherein at least one channel is provided in the catalyst body, wherein the electrical conductor is arranged in the at least one channel. 7. The catalyst body of claim 1 wherein the electrical conductor is elongate. 8. An electrically heated catalyst with the catalyst body as defined in claim 1 and a housing at least circumferentially surrounding the catalyst body, wherein the electrically heated catalyst is electrically contacted on the end face via the at least one electrical contacting assembly. 9. The electrically heated catalyst as defined in claim 8 wherein the catalyst body is surrounded by an insulating mat. 10. A motor vehicle with the electrically heated catalyst as defined in claim 8 . 11. A catalyst body for an electrically heated catalyst with at least one electrical contacting assembly, which comprises: an electrical conductor embedded in the catalyst body and extending in a longitudinal direction of the catalyst body and at least up to one end face of the catalyst body, wherein at least one groove extends in the longitudinal direction in the catalyst body, wherein the electrical conductor is arranged at least partly in the at least one groove, wherein the at least one groove is an elongated recess in a shell surface of the catalyst body. 12. A catalyst body for an electrically heated catalyst with at least one electrical contacting assembly, which comprises: an electrical conductor embedded in the catalyst body and extending in a longitudinal direction of the catalyst body and at least up to one end face of the catalyst body, wherein at least one groove extends in the longitudinal direction in the catalyst body, wherein the electrical conductor is arranged at least partly in the at least one groove, and a surface electrode being arranged on the catalyst body, wherein the surface electrode at least partly covers the at least one groove.
