Abstract:
1. A device for receiving PTC elements in a heating device, having an insulating frame having parallel, spaced longitudinal struts and longitudinally spaced crossbars linking the longitudinal struts, and at least one electrically conductive contact plate held in said insulating frame and on which can be placed the PTC elements, the longitudinal struts and longitudinally spaced crossbars surrounding recesses for receiving the PTC elements, wherein the contact plate is molded in the frame and, at least in a limited longitudinal portion of the frame, the contact plate is completely and tightly surrounded by the frame such that the at least one electrically conductive contact plate cannot be drawn out of the insulating frame without damaging the insulating frame, wherein the contact plate projects past the frame at at least one end of the frame, wherein the frame is made from at least one material selected from the group consisting of plastic, polymer ceramic, wherein, over most of its length, the contact plate is held in grooves of the frame formed in longitudinal struts, and wherein on its side remote from the reception side for the PTC elements, the contact plate is covered by a polymer ceramic or ceramic cover layer, whilst the rest of the frame is made from plastic or polymer ceramic.
