[0025] The fixing seat 5 is pre-installed on the external receiving part, and the temperature sensing element 4 is passed through the fixing seat 5 until the mounting plate 1 is overlapped at the bottom of the fixing seat 5. The plug-in block 13 at the bottom of the mounting plate 1 is inserted into the inside of the coupling groove 11. On the one hand, it can provide axial prestress for the mounting plate 1 and the fixing seat 5. On the other hand, it can make the locking rod 6 just correspond to the screw hole on the fixing seat 5. The fixing of the mounting plate 1 and the fixing seat is completed by the locking rod 6. Finally, the rubber block is interference fit to the top of the mounting plate. The interference fit method ensures the stability of the position of the rubber block 5 itself. The rubber block 7 abuts against the outer wall of the locking rod 6, so that the loosening of the locking rod 6 itself can be limited by friction, thereby ensuring the working stability of the temperature sensor. At the same time, the connecting seat 3 is placed inside the fixing seat 5, and the sealing gasket 12 on the outer wall of the connecting seat 3 abuts against the inner wall of the vertical end of the fixing seat 5, so as to ensure the air tightness between the connecting seat 3 and the fixing seat 5.

[0026] Specifically, Figure 2 and Figure 4 As shown, a plastic holder 8 is fixedly installed on the top of the mounting plate 1. The plastic holder 8 has a triangular structure. A notch 10 is arranged inside the plastic holder 8, and a fixing portion for fixing the wiring harness is arranged at the horizontal end of the plastic holder 8. The fixing portion includes a positioning rod 9, and the outer wall of the positioning rod 9 is screwed and connected with the inner wall of the horizontal end of the plastic holder 8. After the installation of the temperature sensor is completed, the wiring harness is clamped into the inside of the plastic holder 8 through the notch 10, and the positioning rod 9 is rotated. The positioning rod 9 pushes the wiring harness until the wiring harness is positioned with the cooperation of the positioning rod 9 and the plastic holder 8, thereby fixing the wiring harness here. When the outer wiring harness subsequently generates traction due to shaking or pulling, the traction will be transferred to the connection between the wiring harness and the plastic holder 8, and will not be directly transferred to the connection with the terminal 2, thereby further ensuring the stability of the temperature sensor.

[0027] Specifically, Figure 2 and Figure 3 As shown, the alignment component includes an insert block 13, and the outer wall of the insert block 13 is inserted into the top of the horizontal end of the fixing seat 5 through the combination groove 11. On the one hand, it can provide axial prestress for the mounting plate 1 and the fixing seat 5, and on the other hand, it can make the locking rod 6 just correspond to the screw hole on the fixing seat 5. The elastic component includes a rubber block 7, and the outer wall of the rubber block 7 is interference fit with the inner wall of the top of the mounting plate 1, and the bottom of the rubber block 7 is abutted against the top of the locking rod 6. The interference fit method ensures the stability of the position of the rubber block 5 itself. The rubber block 7 abuts against the outer wall of the locking rod 6, so that the loosening of the locking rod 6 itself can be limited by friction. A sealing gasket 12 is fixedly installed on the outer wall of the arc-shaped end of the connecting seat 3, and the outer wall of the sealing gasket 12 abuts against the inner wall of the vertical end of the fixing seat 5.

On the one hand, it can provide axial prestress for the mounting plate 1 and the fixing seat 5, and on the other hand, it can make the locking rod 6 just correspond to the screw hole on the fixing seat 5, and the fixing of the mounting plate 1 and the fixing seat is completed by the locking rod 6. Finally, the rubber block is interference fit to the top of the mounting plate. The interference fit method ensures the stability of the position of the rubber block 5 itself, and the rubber block 7 abuts against the outer wall of the locking rod 6, so that the loosening of the locking rod 6 itself can be limited by friction, thereby ensuring the stability of the temperature sensor. At the same time, the connecting seat 3 is placed inside the fixing seat 5, and the sealing gasket 12 on the outer wall of the connecting seat 3 is in contact with the inner wall of the vertical end of the fixing seat 5, so as to ensure the airtightness between the connecting seat 3 and the fixing seat 5.
