Electric heating device and method for manufacturing the same

A method for producing a PTC heating assembly for an electric heating device, the electric heating device including a housing which forms a receiving pocket in which the PTC heating assembly is received, the PTC heating assembly including at least one PTC element which is received in a positioning frame and strip conductors which are electrically conductively connected to the PTC element for energizing the PTC element with different polarity and which are each covered on an outside surface thereof with at least one insulating layer, the method comprising:

• applying insulating layers on the outside against the strip conductors such that the insulating layers are held via the positioning frame;
• and
• applying profile parts against the insulating layers with the profile parts being held on an outside of the respective insulating layer facing away from the PTC element and captively connecting the profile parts to the positioning frame via form fit segments extending from an upper cross beam of the positioning frame and form fit segments extending from a lower cross beam of the positioning frame so as to form a structural unit comprising the position frame, the PTC element, the strip conductors, the insulating layers, and the profile parts.
