The sheath 22 of conducting wire 21.
It participates in shown in Fig. 3 to Fig. 5, the first fixed part 6 is fixed in end cap 7.Temperature sensor element 5 includes being consolidated by first
The probe 52 for determining the cladding of portion 6 and the draw pin 51 on probe 52.Probe 52 can be PTC thermistor or NTC temperature-sensitive
Resistance.Draw pin 51 is equipped with the tie point 22 being secured together by welding with conducting wire 21.Conducting wire 21 includes elastic portion
211, elastic portion 211 includes the first bending section 2111 of sequentially connected opening upwards, the second bending section 2112 that Open Side Down
And the third bending section 2113 of opening upwards.In the environment of being used for high temperature due to pyrostat 100, so can be because of heat expansion
The reason of shrinkage, generates stress.Under the action of stress, the meeting stress of tie point 22 changes and damages.The utility model is by setting
Elastic portion 211 is set, when generating stress in conducting wire 21, flexible deformation occurs for elastic portion 211, stress absorption is fallen, thus
Avoid damage tie point 22.The utility model passes through the first bending section 2111 of setting, the second bending section 2112 and third bending section
2113, so that elastic portion 211 is in " W " shape." W " shape is advantageous in that, in the case where occupying small in size, can easier be occurred
Flexible deformation.In this way, flexible deformation can also occur for elastic portion 211, by stress even if generating lesser stress inside conducting wire 21
It sponges.
Preferably, the first bending section 2111, the second bending section 2112 and third bending section 2113 are the identical circular arc of radius
Shape.
