Electrical temperature measuring device

An electrical temperature measuring device comprising:

• a temperature sensor arranged in a protective tube, which is closed at one end and opened at another end;
• connection means provided at said open end for connection to electrical lines extending inside the protective tube, wherein said connection means provide that said lines are detachably coupled to external electrical lines;
• a metal screw is fixed to the protective tube in front of said open end and axially protruding over the open end of the protective tube wherein said metal screw surrounds a hollow cylindrical space, which is open at one end and forms the holder for one half of a plug-in connector provided with connector contacts and spring contacts, which are each coated with a precious metal or a precious metal alloy and are made of an electrically conductive metal that is creep-resistant and deformation-resistant in the specified measuring range of the temperature sensor, wherein the connector contacts are connected to the ends of lines extending inside the protective tube and said lines are held in said one half of the plug-in connector inside a first housing made of a glass fiber-filled liquid crystal polymer, and the spring contacts are connected to external lines and are held in another half of the plug-in connector inside a second housing, which is made of the same material as said first housing in which the connector contacts are arranged.
