[0021] The second energy absorbing plate 404 is provided with first energy absorbing grooves 405 on both sides, the cross-sectional shape of the first energy absorbing grooves 405 is conical, and a replacement seat 403 is sleeved on the side of the second energy absorbing plate 404 close to the energy absorbing ring 401, and the replacement seat 403 is connected to the corresponding position on the inner cavity side of the energy absorbing ring 401, and the cross-sectional shape of the through hole 407 is equal to the shape of the first energy absorbing plate 402 or the second energy absorbing plate 404.

[0022] Specifically, when the connecting structure is connected to the temperature sensor, it can be connected to the tail port of the temperature sensor through the wiring harness terminal 2, and the wiring harness can be connected to the data collection interface through the wiring arrangement mechanism 6. When the wiring harness is pulled, the wiring arrangement mechanism 6 can pull the inner buffer mechanism 5 through the rear end cover 9 to absorb energy. At the same time, the rear end cover 9 can pull the energy absorbing ring 401 to move, and the first energy absorbing plate 402 and the second energy absorbing plate 404 connected to the inner side of the energy absorbing ring 401 can contact the energy absorbing sheet 406.

[0024] Furthermore, through the designed wire management groove 604, the wire harness led out from the lead-in seat 603 can be inserted into the wire management wheel 605 at the bottom side of the wire management groove 604. At this time, the abutment of the wire management wheel 605 can prevent the led-out wire harnesses from being entangled with each other, thereby ensuring the arrangement stability of the wire harnesses after being led out. In addition, when an impact occurs, the wire management groove 604 can drive the connecting column 608 to squeeze the external first energy absorbing spring 609 by moving. The first energy absorbing spring 609 can use its own elastic force to absorb the shaking and displacement of the wire management groove 604 and the wire harness, which is beneficial to further stabilize the arrangement of the wire harnesses, improve the impact resistance and improve the arrangement stability of the temperature sensor, and the stabilizing plate 606 can slide in the sliding hole on one side of the fixed column 607 through the rear sliding rod 610 to drive the wire management wheel 605 to slide, which is beneficial to straighten the wire harnesses through the movement of the slidable wire management wheel 605, and can improve the stability of the temperature sensor extending to the external terminal after connection through the arrangement of the wire harnesses, thereby further improving the extension support effect of the connection structure on the wire harnesses. At the same time, the cable wheel 605 can make the wire harness slide easily when passing through through the sliding structure, avoiding wire damage caused by friction. At the same time, the sliding characteristics of the cable wheel 605 help to adjust the arrangement of the wire harness to make it more neat and orderly. The wire harness can be combed during movement to reduce signal interference caused by wire harness entanglement. The neat arrangement of the wire harness makes the extension of the wire harness to the external terminal after the temperature sensor is connected more stable, reducing the deformation of the wire harness caused by external force, ensuring that the wire harness remains stable during long-term use. In addition, the good support effect also helps to reduce the wear between the wire harness and the connector, and extend the service life of the connector. When the temperature sensor and terminal equipment need to be maintained and repaired, the staff can quickly find the target wire harness and improve work efficiency. The sliding cable wheel 605 facilitates the replacement of the wire harness and reduces the maintenance cost.
