Abstract

The invention relates to an electrical connection of a plurality of sheet metal layers (1, 2, 3, 4) of a honeycomb body (14) at a connection pin (12), wherein the honeycomb body (18) has a metal shell (7) with an inner periphery (I), through which the connection pin (12) is led in a bushing (10) so as to be electrically insulated, and wherein the sheet metal layers (1, 2, 3, 4) are alternately arranged coarsely structured metal sheets (2) and finely structured or smooth metal sheets (1), which together form a Stack (5) with an uppermost sheet metal layer (3) and a lowermost sheet metal layer (4), the Stack having Channels (15) through which a gas can flow in an axial direction (A) between the sheet metal layers (1, 2, 3, 4). The invention is characterized in that the connection pin (12) runs approximately perpendicular to the sheet metal layers (1, 2, 3, 4) and thus in a radial direction (R), and is metallically connected to at least two, preferably all, of the sheet metal layers (1, 2, 3, 4) via at least one intermediate piece (13), wherein the uppermost sheet metal layer (3) in the Stack (5) preferably runs approximately parallel to the metal shell (7) over at least 35% of the inner periphery (I) and is separated therefrom only by an air gap (8). The invention enables simple production of an operationally safe and very uniformly electrically heatable honeycomb body (14).
