[0025] In order to clearly and completely describe the purpose, technical solution of the present utility model, and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0026] Embodiment 1, please refer to Figures 1 - 6 , the present utility model provides a technical solution: a cable with a temperature sensing function, a cable core 2 is fixed inside the cable body 1, a through groove 3 is opened on the end face of the cable body 1. Since the increase in temperature will promote air circulation, the air in the through groove 3 will flow towards the place where the temperature rises. The through groove 3 penetrates the cable body 1, and a drainage block 10 is fixed on the inner wall of the through groove 3. The spiral drainage block 10 conducts dredging, accelerating the process of air circulation inside the through groove 3.

[0027] A sector block 12 is fixed on the inner wall of the metal shell 4, and a connecting pipe 13 is inserted inside the sector block 12. The place where the temperature rises will transmit the temperature of the cable body 1 and the temperature in the through groove 3 to the metal shell 4 through the connecting pipe 13, and then the metal shell 4 transmits the temperature to the corresponding temperature-sensitive material 5, causing the color of the temperature-sensitive material 5 to change, facilitating the operator to cool down the cable. The temperature-sensitive material 5 is fixed on the outer surface of the metal shell 4.

[0028] On the basis of Embodiment 1, in order to realize the display of the temperature change of the cable body 1, a connection groove 7 is opened on the outer surface of the cable body 1, a sector groove 6 is opened on the inner wall of the connection groove 7, a first through hole 8 is opened on the inner wall of the through groove 3, a first annular groove 9 is opened on the inner wall surface of the first through hole 8, and the first through hole 8 communicates the sector groove 6 and the through groove 3.

[0029] Four sets of metal casings 4 are sleeved on the outer surface of the cable main body 1. Connecting blocks 11 are fixed to the inner wall of the metal casing 4. Sector-shaped blocks 12 are fixed to the surface of the connecting blocks 11. First annular blocks 18 and second annular blocks 19 are fixed to the outer surface of the connecting pipe 13. Installation grooves 14 are formed on the outer surface of the metal casing 4, and the connecting blocks 11 correspond to the installation grooves 14.

[0030] Grooves 15 are formed inside the connecting blocks 11. Second through holes 16 are formed on the inner wall of the grooves 15. Second annular grooves 17 are formed on the inner wall of the second through holes 16. The second through holes 16 communicate with the inner wall of the metal casing 4 and the grooves 15. Since metal has good thermal conductivity, the metal casing 4 can transfer temperature to the temperature-sensitive material 5 more efficiently.

[0031] Multiple groups of temperature-sensitive materials 5 are provided. The multiple groups of temperature-sensitive materials 5 are circumferentially distributed on the outer surface of the metal casing 4. Multiple groups of installation grooves 14 are formed. The multiple groups of installation grooves 14 are circumferentially distributed on the outer surface of the metal casing 4. The temperature-sensitive materials 5 correspond to the installation grooves 14 and are clamped therein, and the two are movably connected. The metal casing 4 can transfer temperature to the temperature-sensitive material 5 more efficiently. The change in temperature will change the color of the temperature-sensitive material 5, thereby displaying the temperature change of the cable main body 1 in real time, which is convenient for the operator to cool down the cable.

[0032] Multiple groups of first through holes 8 are formed. The multiple groups of first through holes 8 are symmetrically distributed inside the cable main body 1. Multiple groups of connecting pipes 13 are provided. The multiple groups of connecting pipes 13 are symmetrically distributed inside the cable main body 1, and the connecting pipes 13 correspond to the first through holes 8 and are clamped therein, and the two are movably connected. The first through holes 8 correspond to and communicate with the second through holes 16.

[0033] The first annular block 18 corresponds to and is clamped in the first annular groove 9, and the two are movably connected; the second annular block 19 corresponds to and is clamped in the second annular groove 17, and the two are movably connected. The first annular block 18 and the second annular block 19 are made of rubber material, which is convenient for clamping.

[0034] In actual use, the metal shell 4 is made of ductile metal and can be bent. When the temperature of the cable body 1 rises due to long-term use, the cable body 1 will transfer its own temperature to the metal shell 4. Since metal has good thermal conductivity, the metal shell 4 will transfer the temperature to the temperature-sensitive material 5 more efficiently. The change in temperature will change the color of the temperature-sensitive material 5, thus showing the temperature change of the cable body 1 in real time, which is convenient for the operator to cool down the cable. When the temperature of a certain section of the cable body 1 rises, the increase in temperature will promote air circulation. The air in the through groove 3 will flow towards the place where the temperature rises, and is dredged through the spiral drainage block 10, which speeds up this process. The place where the temperature rises will transfer the temperature of the cable body 1 and the temperature in the through groove 3 to the metal shell 4 through the connecting pipe 13, and the metal shell 4 will then transfer the temperature to the corresponding temperature-sensitive material 5, causing the color of the temperature-sensitive material 5 to change, which is convenient for the operator to cool down the cable.
