Heating device with temperature sensor

A heating device for heating an injection molding die, the heating device comprising:

• an inner jacket defining an inner surface for contact with the injection molding die;
• an outer jacket with an outer surface;
• a heating element disposed between said inner jacket and said outer jacket;
• a thermocouple disposed between said inner jacket and said outer jacket, said thermocouple having a positioning section with a positioning cross section which has a dimension that deviates from a cross section of another section of the thermocouple and a cross section of yet another section of the thermocouple, said positioning section comprising a sleeve, said another section and said yet another section being located adjacent to said sleeve, wherein said another section is located on one side of said sleeve and said yet another section is located on another side of said sleeve, wherein said thermocouple has different diameters, said inner jacket surface and said outer jacket surface defining a heating device interior space, said heating element being arranged in said heating device interior space, wherein said heating element is located between said inner jacket surface and said outer jacket surface;
• a locking means for locking said positioning section against a displacement of said thermocouple in either direction along which said thermocouple extends, wherein said locking means comprises a projection of said inner jacket surface, said projection having a portion extending radially in a direction of said thermocouple with respect to a longitudinal axis of said thermocouple, wherein said portion of said projection is located axially adjacent to said sleeve with respect to said longitudinal axis of said thermocouple.

A heating device, for arrangement at an object to be heated, the heating device comprising:

• an inner jacket surface;
• an outer jacket surface;
• a heating element located between said inner jacket surface and said outer jacket surface;
• a thermocouple comprising a sensor tip and at least one positioning section, said at least one positioning section comprising at least one positioning cross section, said at least one positioning cross section having a dimension that deviates from a second cross section of a second section of the thermocouple and a third cross section of a third section of the thermocouple, said second section and said third section being located adjacent to said at least one positioning section, wherein said second section is located on one side of said at least one positioning section and said third section is located on another side of said at least one positioning section;
• and
• at least one locking means for locking said at least one positioning section against one or more of a displacement of said at least one positioning section in a direction in which said thermocouple extends and a displacement of said at least one positioning section opposite to the direction in which said thermocouple extends, said at least one locking means and said at least one positioning section being located at a spaced location from said sensor tip, said at least one locking means comprising at least one projection, said inner jacket surface defining said at least one projection, said at least one projection comprising at least one projection portion extending in a radial direction with respect to a longitudinal axis of said thermocouple, wherein a portion of said at least one positioning section is located opposite said at least one projection portion with respect to said longitudinal axis of said thermocouple.
