20120248091 | ELECTRICAL HEATING DEVICE WITH A PLATE ELEMENT COMPRISING CONDUCTIVE PATHS AND METHOD FOR THE MANUFACTURE OF A PLATE ELEMENT OF THIS NATURE - An electrical heating includes a plurality of electrical heating elements which are held by a housing and which abut heat conducting surfaces over which a medium to be heated flows. The electrical heating elements comprise contact lugs, arranged essentially at the same height, that are connected through a plate element. The plate element includes conductive paths and contact lug receptacles for the contact lugs. The plate element may include a carrier plate of non-conducting material and a stamped out metal plate that are joined together to form one unit. A method of manufacturing a plate element includes manufacturing the carrier plate by injection moulding and subjecting a metal plate to stamping operations to form area elements which are joined together by connecting ridges and in which the contact lug receptacles are located. The carrier plate and the metal plate are then joined, and the connecting ridges are then parted. | 10-04-2012 |
