Claims (1)

[Scope of Claim for Utility Model Registration] 1. In the output lead-out structure of a temperature-measuring element for connecting an extension cable to the temperature-measuring element, an outer tube made of a heat-resistant material is provided at either the lead-out end of the temperature-measuring element or the starting end of the extension cable. The case and the center pin are formed concentrically, and male terminals are attached at different positions in the axial direction of the center pin, and contact electrodes made of the same material as each pole element wire of the temperature measuring element are provided around the entire circumference, The other side has a cylindrical case made of a heat-resistant material that is fitted into the outer cylindrical case of the male terminal and externally supports the central pin, and a portion of the inner surface of the cylindrical case that contacts the central pin is provided with a cylindrical case made of a heat-resistant material. This is the output derivation structure of the temperature measuring element, which is provided with a female terminal with an outer electrode made of the same material as the contact electrode of the center pin which is the contact partner. 2. The above-mentioned utility model registration claim in which one shaft-shaped contact electrode with a bulge at its tip is inserted through the other cylindrical contact electrode through an insulating material to form a central pin. Output derivation structure of the temperature measuring element according to scope 1. 3. The output deriving structure of the temperature measuring element according to claim 1 or 2, wherein the tip of the central pin is positioned inward from the open end of the outer cylindrical case. 4 Claim 1 of the above-mentioned utility model registration, wherein an elastic pressing member is provided at a suitable position on the inner peripheral surface of the female terminal that externally supports the central pin for bringing the contact electrode of the central pin into contact with the opposite inner peripheral surface. Output derivation structure of the temperature measuring element according to item 1, 2 or 3. 5. Claims 1, 2, 3, or 5 of the above-mentioned utility model registration claim in which a plate spring is used as the elastic pressing member, and the elastically deformed portion of the plate spring is brought into point contact with the contact electrode of the central pin. Output derivation structure of the temperature measuring element according to item 4.
