[0028] An interlayer 5 is formed between the temperature sensor 2, the mounting portion 101 and the fixing piece 4, which is due to the gap formed by the size difference between the temperature sensor 2, the mounting portion 101 and the fixing piece 4 after the fixing piece 4 is shrunk, the thickened portion 402 is extruded in the interlayer 5 along with the shrinkage of the fixing piece 4 after the fixing piece 4 is shrunk, the interlayer 5 is isolated from the outside, the air gap between the temperature sensor 2 and the mounting portion 101 is avoided, and air flow is also prevented, which influences the temperature measurement accuracy and the thermal response time.

[0030] With reference to Figures 1-5 Further to the embodiment 1, the temperature sensor 2 is provided with a connecting wire 3, the connecting wire 3 is spirally wound by two groups of wire bundles at a fixed pitch; the fixing member 4 is provided with an anti-skid block 401; the anti-skid block 401 is provided with a groove 4011; when the temperature sensor 2 is fixed on the surface of the mounting portion 101 through the fixing member 4, the anti-skid block 401 is attached to the back of the mounting portion 101; and the fixing member 4 is a heat shrinkable sleeve.

[0031] The connecting wire 3 is spirally wound by two groups of wire bundles at a fixed pitch, and through the symmetrical twisting between the two wire bundles, the induced current generated by the external electromagnetic interference (EMI) on the two wires is equal in size and opposite in direction, thereby canceling each other (i.e. common mode noise suppression);
