Abstract
Official abstract text for this publication.
An electrically heated catalyst has a catalyst body and a housing at least circumferentially surrounding the catalyst body. An electrical contacting assembly is arranged on a shell surface of the catalyst body, the electrical contacting assembly comprising a surface electrode arranged directly on the catalyst body and a contacting element connected to the surface electrode. The contacting element is rigid and has a screw thread.
First claim
Opening claim text (preview).
The invention claimed is: 1. A catalyst body for an electrically heated catalyst: at least one electrical contacting assembly arranged on a shell surface of the catalyst body, the at least one electrical contacting assembly comprising a surface electrode arranged directly on the catalyst body and a rigid contacting element connected to the surface electrode, wherein the contacting element has a screw thread. 2. The catalyst body according of claim 1 wherein the rigid contacting element is arranged directly on the surface electrode. 3. The catalyst body according of claim 1 wherein the catalyst body has a depression and the rigid contacting element is arranged in the depression in such a way that the rigid contacting element does not protrude beyond an outer surface of the catalyst body. 4. The catalyst body of claim 1 wherein the rigid contacting element is adhered to the surface electrode. 5. The catalyst body of claim 1 wherein the rigid contacting element is secured to a contact element, in particular a flexible contact element, wherein the flexible contact element is arranged on the surface electrode. 6. The catalyst body of claim 1 wherein the rigid contacting element is a nut. 7. An electrically heated catalyst with the catalyst body of claim 1 and a housing at least circumferentially surrounding the catalyst body, and wherein a screw is screwed into the rigid contacting element for electrically contacting the electrically heated catalyst. 8. The electrically heated catalyst of claim 7 wherein the rigid contacting element is arranged completely inside the housing. 9. The electrically heated catalyst of claim 7 wherein at least one opening is provided in the housing, wherein the at least one opening is arranged over the rigid contacting element in such a way that the rigid contacting element is accessible via the at least one opening. 10. The electrically heated catalyst of claim 9 wherein a cover is arranged over the at least one opening, in particular wherein the cover is held on the catalyst body by the screw. 11. The electrically heated catalyst of claim 7 wherein the catalyst body is surrounded by an insulating mat. 12. A motor vehicle with the electrically heated catalyst of claim 7 .
