[0044] In the embodiment of the application, the specific work flow of the part of the application embodiment is as follows: during the process of installing the cable in the cable connector 1031, the cable is extruded to the inside of the hollow annular plate 303 through the movement of the lifting annular column 301, in the process of moving the lifting annular column 301, the compressed air in the hollow annular plate 303 is driven to be transmitted to the air pressure cabin formed between the sliding block 210 and the sliding groove 211 through the three-hole pipe 302, and the sliding block 210 is driven to move to the position of the temperature sensing hollow column 207, when the cable is connected with the cable connector 1031, one group of elastic ring plates 214 close to the top of the temperature sensing hollow column 207 is moved to one group of limiting grooves of the hollow clamping column 208, by manually pressing the first protective shell 201, the first protective shell 201 and the second protective shell 202 are driven to be in the connected state, at this time, the two groups of elastic ring plates 214 are moved to the two groups of limiting grooves of the hollow clamping column 208, at this time, the first protective shell 201 and the second protective shell 202 are in a temporary limiting state, and an additional limiting force is exerted on the cable and the cable connector 1031, further enhancing the connection force between the cable and the cable connector 1031, and reducing the risk of falling between the two to a certain extent.

[0045] When the temperature between the cable and the cable connector 1031 exceeds the optimal working range, the temperature conduction plate 203 senses the temperature change and transmits the temperature change to the inside of the temperature sensing hollow column 207 through the auxiliary conduction plate 206.
