  • Patent number: 10525624
    Abstract: A heating element for flow channel heating or for heating a mould impression and an injection-moulding nozzle incorporating the heating element are disclosed. The heating element has a carrier element which carries a heating conductor with first and second connection pins, and a connection device with an electrical connection cable with first and second conductors. The first and second connection pins end in an insulator. The insulator is arranged at least in certain portions in a receiving sleeve of the connection device, and the receiving sleeve points with a first end in the direction of the carrier element, is fixed with the first end on the carrier element and fixes the insulator in relation to the carrier element. A first crimping sleeve is fixed on the first connection pin and the first conductor, and a second crimping sleeve is fixed on the second connection pin and the second conductor.

  • Patent number: 8840395
    Abstract: A hot runner nozzle having an electrical heating element includes a connector for producing an electrical connection to a connection line, terminal contacts for the heating element terminating in an insulation body for the connector that separates the terminal contacts from one another electrically. The connection line has contact elements that are electrically contactable with the terminal contacts of the heating element. The insulation body is arranged at least in part in a receiving sleeve of the connector, that the connection line may be fixed in or on the receiving sleeve such that the contact elements of the connection line electrically contact the terminal contacts of the heating element, and that a first end of the receiving sleeve that faces towards the heating element wraps around the insulation body and has on this first end two opposing feet that face outward and that are attached to the heating element.
