HEATING ELEMENT FOR A FLOW CHANNEL OR A MOULD IMPRESSION AND INJECTION-MOULDING NOZZLE WITH SUCH A HEATING ELEMENT

摘要

The invention relates to a heating element (1) for flow channel heating or for heating a mould impression that has a carrier element (10), which carries a heating conductor (20) with a first connection pin (21) and a second connection pin (22), and that comprises a connection device (30) with an electrical connection cable (40) with a first and a second conductor (41, 42), wherein the first and second connection pins (21, 22) end in an insulator (50) of the connection device (30), wherein the insulator (50) is arranged at least in certain portions in a receiving sleeve (60) of the connection device (30), and wherein the receiving sleeve (60) points with a first end (61) in the direction of the carrier element (10), is fixed with the first end (61) on the carrier element (10) and fixes the insulator (50) in relation to the carrier element (10), and wherein a first crimping sleeve (44) is fixed on the first connection pin (21) and a second crimping sleeve (45) is fixed on the second connection pin (22), in each case by plastic deformation, and the first crimping sleeve (44) is fixed on the first conductor (41) and the second crimping sleeve (45) is fixed on the second conductor (42), in each case by plastic deformation. The invention also relates to an injection-moulding nozzle (100), the material tube (102) of which is thermally coupled to such a heating element (1).
