Temperature measuring device for electrical contact element

A temperature measuring device for measuring a temperature of a pin-shaped electrical contact element, the temperature measuring device comprising:

• a flexible circuit board comprising:
• a first thermally conducting and electrically insulating substrate layer comprising:
• a contact surface that is configured to lie flat against a flange of the pin-shaped electrical contact element;
• and
• an opening disposed in the contact surface, wherein the pin-shaped electrical contact element is at least partially disposed in the opening;
• and
• a second thermally and electrically conducting layer that is disposed on a sensor surface opposite the contact surface of the first thermally conducting and electrically insulating substrate layer and includes a sensor element connected to the sensor surface, which is configured to record a temperature of the pin-shaped electrical contact element when the pin-shaped electrical contact element is disposed at least partially in the opening and the sensor element comprises a flat conductor path that is disposed on the sensor surface and comprises a temperature probe that is thermally connected to the flat conductor path.
