Abstract (en)
[origin: US2007023418A1] A cartridge heater, especially a compressed cartridge heater ( 1 ) has at least one heating coil ( 8, 9 ), which is arranged exposed in a metallic tubular body ( 2 ) and is embedded in a granulated insulating material. The ends of heating coil portions ( 8, 9 ) are provided with terminals ( 7 ) projecting from the tubular body ( 2 ). To make it possible to manufacture such a cartridge heater with minimal effort in terms of labor and material, a flat insulating plate ( 10 ) coordinated in its width with the internal diameter of the tubular body ( 2 ) is provided as the carrier. The heating coils ( 8, 9 ) extend along the two flat sides of the insulating plate ( 10 ) and the two heating coils ( 8, 9 ) are connected to one another by a coil section ( 12, 12' ), which is led around a deflecting edge ( 27 ) of the insulating plate ( 10 ).
