When the line connector and the cable have poor contact, sparks are likely to be generated, and severe cases may even cause a short circuit in the line and cause an accident. When the line connector and the cable are separated, the circuit will be cut off, causing the line to be unable to operate normally.

A plurality of docking rods 16 symmetrically distributed on the left and right are provided in the fastening cavity 2, and the two symmetrical docking rods 16 are connected by a transition connecting rod 1601. The docking rods 16 are respectively inserted into the fastening sleeve 10 on the corresponding side, and both ends of the docking rod 16 are hollow structures, which is convenient for the cable 5 to be inserted into the hollow structure of the corresponding end of the docking rod 16.

[0023] In this embodiment, when the electrical engineering line 4 is connected, the end of the electrical engineering line 4 is inserted into the protective sleeve 3, and then the insulating jacket of the end of the cable 5 in the electrical engineering line 4 is stripped off and inserted into the end of the docking rod 16 in sequence, and then the worm 12 is rotated to drive the worm wheel 11 to rotate, and the worm wheel 11 drives the threaded rod 13 to rotate. Under the cooperation of the threaded rod 13 and the threaded sleeve 14, the fastening sleeve 10 is driven to be inserted into the docking channel 6, and the outer wall of the fastening sleeve 10 is in contact with the inner wall of the docking channel 6, and the fastening sleeve The inner wall of the tube 10 fits with the outer side of the docking rod 16, so that a spiral channel is formed between the spiral groove 7 and the side wall of the fastening sleeve 10, and the fastening sleeve 10 squeezes the docking rod 16.

[0024] After the docking is completed, when airflow is generated outside, the turntable 17 is driven to rotate, and the fan blades 18 direct the external airflow into and out of the air inlet channel 9, and then discharge it from the exhaust channel 8 after passing through the spiral channel. The airflow generated by the fan blades 18 flows in the spiral channel surrounding the docking channel 6 to dissipate heat at the connection between the cable 5 and the docking rod 16.

[0025] Embodiment 2: Figure 7-9 As shown: The difference from Example 1 is that two worm wheels 11 and worm 12 are symmetrically arranged in the fastening cavity 2, which respectively drive the fastening sleeves 10 on the left and right sides of the fastening cavity 2 to slide in the docking channel 6, and a first partition 201 is arranged at both ends of the fastening cavity 2, and a second partition 202 is arranged in the middle of the fastening cavity 2, and a positioning sleeve 21 is arranged between the second partition 202 and the first partition 201, and the bottom end of the positioning sleeve 21 is fixedly connected to the first partition 201, and a gap is left between the top of the positioning sleeve 21 and the second partition 202, and a buffer line 20 is fixed on the second partition 202, and the number of buffer lines 20 corresponds one by one to the number of cables 5 in the electrical engineering line 4, and the buffer line 20 is inserted into the positioning sleeve 21 from the top end face of the positioning sleeve 21, and then passes through the side wall of the positioning sleeve 21 and is spirally wound on the positioning sleeve 20, and then the ends of the buffer line 20 are respectively connected to the corresponding docking rods 16.

[0026] In this embodiment, semicircular spring pieces 22 are evenly distributed on the side wall of the positioning sleeve 21, both ends of the spring pieces 22 are fixedly connected to the positioning sleeve 21, a limiting support plate 23 is fixed to the raised portion in the middle of the spring piece 22, and the inner side of the limiting support plate 23 is arranged in an arc-shaped structure to facilitate the buffer circuit 20 to be inserted into the limiting support plate 23 and be limited.

[0027] In this embodiment, when an external force pulls the cable 5, the pulling force at the connection between the cable 5 and the docking rod 16 changes, and the connection between the docking rod 16 and the cable 5 slides and moves relative to each other in the tightening sleeve 10. The buffer circuit 20 tightens and squeezes the spring piece 22. The tightening of the buffer circuit 20 is used to provide a buffer margin for the contraction of the cable 5, thereby preventing the connection between the docking rod 16 and the cable 5 from being loosened due to excessive pulling force. During the process of the compressed spring piece 22 returning to its original state, the buffer circuit 20 is loosened to compensate for the elongation of the cable 5, thereby ensuring that the pulling force acting on the connection between the docking rod 16 and the cable 5 is always maintained within the set range, thereby preventing the connection between the cable 5 and the docking rod 16 from being loosened.
