ABSTRACT:
The invention relates to a heating device for diesel fuel comprising at least one PTC heating element (8), at least two contact sheets (7) each comprising a front face (10) by means of which they contact the PTC heating element (8) electrically, wherein the PTC heating element (8) is provided between the front faces (10) of the two contact sheets (7); a plastic housing (2) enclosing an interior space through which the diesel fuel to be heated can flow and in which the PTC heating element (8) and the contact sheets (7) are provided. According to the invention, it is provided that the front faces (10) of the contact sheets (7) project, on at least one longitudinal side, over the PTC heating element (8) so that a gap is provided between the opposing front faces (10) of the contact sheets (7), that the housing (2) comprises positioning elements (11) projecting into its interior space, engaging into the gap and, as a stop, securing the PTC heating element (8) against lateral displacement, and that the contact sheets (7) each have at least one leg (12) bent away from the front face (10) and being pressed into the housing (2) with prestress so that the front faces (10) of the contact sheets (7) are pressed against the PTC heating element (8) by spring forces exerted by the legs (12).
