Electrical feedthrough and method for the production thereof

An electrical feedthrough configured to contact a heating conductor of an electrically heatable honeycomb body, comprising:

• a pin that is electrically conductive;
• an insulation layer that is electrically insulating;
• and
• a bushing in which the insulation layer and the pin are at least partially accommodated,
• wherein the pin is arranged centrally and at least some portions of the pin are completely surrounded in a circumferential direction by the insulation layer,
• wherein the pin, the insulation layer, and the bushing are connected to one another by a form fit and/or a force fit such that they cannot be separated non-destructively.

A method for producing an electrical feedthrough having an electrically conductive pin, an electrically insulating insulation layer;

• and a bushing in which the insulation layer and the pin are at least partially accommodated, comprising:
• arranging the pin centrally and at least some portions of the pin are completely surrounded in a circumferential direction by the insulation layer;
• applying a force component to at least one of the components from the bushing, pin or insulation layer after assembly;
• and
• producing a permanent plastic deformation of at least that component to which the force component has been applied.
