Electric heating device

摘要

The housing has a housing lower part that forms a retainer for a heating block and a frame surrounding the retainer, and a housing upper part that is attached to the housing lower part for inclusion of the heating block and includes guiding pins (76, 78, 80). The retainer and the pin guides form functional surfaces. An outer contour of the housing lower part provides contour surfaces, and the guiding pins form another functional surface. A cover (88), which limits peripheral surfaces of the housing upper part, runs parallel or perpendicular to a plane having a frame opening (16).
