[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The following is combined with Figure 1-5 This application is described in further detail.

[0028] Reference Figures 1 to 3 A melt temperature sensor includes a detection head 5 and a conversion part 3, a sensing chip 6 is fixedly arranged in the detection head 5, the detection head 5 is fixedly connected with a connecting wire 12, the connecting wire 12 is electrically connected to the sensing chip 6, the conversion part 3 is connected to the connecting wire 12, the end of the conversion part 3 away from the connecting wire 12 is connected to the transmission wire 1, the end of the transmission wire 1 close to the conversion part 3 is fixedly provided with a connector 9, and the connector 9 is connected to the conversion part 3.

[0029] When in use, connect the transmission wire 1 to the display, then put the detection head 5 into the object to be measured, the temperature information sensed by the sensing chip 6 is transmitted to the conversion part 3 via the connecting wire 12, and the conversion part 3 transmits the processed temperature information via the transmission wire 1 to the display for display.

[0030] Reference Figure 1The conversion part 3 includes a mounting shell 8 and a transmitter 7. The transmitter 7 is mounted in the mounting shell 8. A connector 11 is fixedly arranged on the mounting shell 8. The connector 11 is electrically connected to the transmitter 7. A connecting wire 12 is connected to the connector 11. A plug 10 is fixedly arranged on the mounting shell 8. The plug 10 is electrically connected to the transmitter 7. A connector 9 is connected to the plug 10. The arrangement of the plug 10 and the connector 11 facilitates switching of the signal display source according to the usage. An anti-bending spring 2 is fixedly arranged on the connector 9. The anti-bending spring 2 is sleeved on the transmission wire 1.

[0031] The anti-bending spring 2 has resilience. When the connection between the mounting shell 8 and the transmission conductor 1 is bent or folded, the anti-bending spring 2 quickly rebounds the transmission conductor 1 to its original shape, thereby reducing the bending or folding of the transmission conductor 1 and the risk of the transmission conductor 1 breaking, thereby achieving the effect of preventing the transmission conductor 1 from breaking.

[0032] Reference Figure 2 The transmission conductor 1 and the connecting conductor 12 are both made of high temperature resistant materials, such as high temperature metal armored cable or metal glass fiber composite high temperature cable. The melt temperature sensor is used to measure the temperature of high temperature liquid. The connecting conductor 12 and the transmission conductor 1 made of high temperature resistant materials have high temperature resistance, which can extend the service life of the melt temperature sensor and make the melt temperature sensor less prone to damage.

[0033] Reference Figure 2 and Figure 5 The connecting wire 12 is provided with a metal glass tube 4, which has the advantages of wear resistance, folding resistance and high-temperature heat dissipation. The use of the metal glass tube 4 enhances the use effect of the melt temperature sensor. At the same time, the bending angle of the metal glass tube 4 has a certain limit, which can protect the connection between the mounting shell 8 and the connecting wire 12 from being easily folded and broken.

[0034] Reference Figure 3 and Figure 5 The metal glass tube 4 is provided with corrugated strips 13, which are threadedly arranged on the metal glass tube 4. The corrugated strips 13 increase the contact area between the metal glass tube 4 and the air, so that the heat dissipation effect of the metal glass tube 4 is better.

[0035] The implementation principle of this embodiment is as follows: the anti-bending spring 2 is elastic. When the connection between the mounting shell 8 and the transmission conductor 1 is bent and folded, the anti-bending spring 2 quickly rebounds the transmission conductor 1 to its original shape. Moreover, the angle of the anti-bending spring 2 is relatively gentle when it is bent under force, which can better protect the transmission conductor 1 and reduce the risk of the transmission conductor 1 breaking, thereby achieving the effect of not making the transmission conductor 1 break easily.
