[0028] like Figures 1 to 5As shown, a heat-shrinkable terminal cable accessory includes a housing 1, a cable 6, a heat-conducting component, and a tightening component. The cable 6 is disposed inside the housing 1.

[0029] Furthermore, such as Figure 1 , 2 as well as Figure 3 As shown, a heat-conducting component, disposed on one side and inside the housing 1, is used to collect and guide hot air from the outside of the accessory into the inside of the accessory evenly, triggering the heat shrinking effect. It includes multiple air-guiding channels 4, which are fixedly formed on the surface of the housing 1. One end of each air-guiding channel 4 is connected to an air duct 5. A heat shrink tubing body 14 is disposed on the outside of the cable 6. The air duct 5 spirally surrounds the outside of the heat shrink tubing body 14. A guide groove 7 is formed inside the air duct 5, and a guide block 8 is fixedly connected inside the guide groove 7. The guide block 8 is connected to the air duct 5. The inner wall is fixed. Multiple air guide plates 3 are installed on one side of the outer side of the air duct 4, located on the shell 1. An inclined plate 2 is fixedly connected between two air guide plates 3. Guide grooves 7 and guide blocks 8 are positioned at 30 to 60 degrees inside the air duct 5. The air guide plate 3 is an arc-shaped plate-like part. Two air guide plates 3 form a group. The air guide plates 3 are positioned at 45 degrees outside the air duct 4. The air duct 5 is located inside the shell 1. One end of the air duct 5 is connected to the air duct 4, and the other end of the air duct 5 passes through one side of the shell 1 and connects to the outside. The combination of slot 4, air duct 5, and air guide plate 3 allows hot air to be evenly introduced from the outside and effectively guided into the interior of the accessory, helping to trigger the heat shrink effect. This design ensures that the distribution of hot air inside the accessory is more uniform, thereby improving the efficiency of the heat shrink effect. The air duct 5 is spirally wrapped around the outside of the heat shrink tube body 14, and the direction and speed of the hot air flow are effectively controlled by the guide slot 7 and guide block 8. It can achieve strong guidance and heat transfer functions in a limited space. The setting angle of the guide slot 7 and guide block 8 inside the air duct 5 can precisely control the flow of airflow, ensuring that the hot air can be concentrated and effectively transferred to the target area, avoiding heat waste. Multiple air guide plates 3 are combined with the air duct 4 through reasonable angle settings, which can better change and distribute the airflow direction, making the guidance and flow of hot air more uniform and efficient. The design of the two ends of the air duct 5 allows hot air to enter and exit through the opening of the shell 1, which not only avoids excessive accumulation of hot air, but also prevents airflow obstruction, thereby improving the ventilation and heat dissipation effect of the entire system.

[0030] Furthermore, such as Figure 1 , 4 as well as Figure 5The tightening assembly, located on one side of the housing 1, is used to limit the contact point between the cable 6 and the housing 1, ensuring the cleanliness and safety of the interior of the housing 1. It includes a limiting sleeve 9, threadedly connected to one end of the housing 1. A fixing ring 13 is fixedly connected inside the limiting sleeve 9. Multiple rotating plates 12 are rotatably connected to one side of the fixing ring 13. A rotating ring 11 is located at the other end of the rotating plate 12. A ratchet is fixedly connected to one side of the rotating ring 11. A top block that engages with the ratchet on the rotating ring 11 is fixedly connected to the fixing ring 13. A rotating ring 10 is fixedly connected to the outer side of the rotating ring 11. The rotating plate 12 is an arc-shaped plate-like part. The multiple rotating rings 11 are close to each other, with a circular hollowed-out shape in the middle. One side of the rotating plate 12 is connected to... The fixed ring 13 is rotatably connected, and the other side of the rotating plate 12 contacts the rotating ring 11. The limiting sleeve 9 is threadedly connected to one end of the housing 1, ensuring that the component can be firmly fixed on the housing 1, effectively limiting the position of the cable 6 in contact with the housing 1, thereby preventing the cable 6 from moving excessively or being damaged, and ensuring the cleanliness and safety of the inside of the housing 1. The design of the rotating plate 12 and the rotating ring 11 allows the limiting position to be adjusted as needed. The rotating ring 11 provides a precise locking mechanism by cooperating with the top block. The ratchet on the rotating ring 11 and the top block work together to ensure that the rotating ring 11 can be firmly locked in position after adjustment, avoiding misoperation or loosening, thereby enhancing safety and preventing accidental damage to internal components.

[0031] Workflow

[0032] When using the device, first put the housing 1 on the cable 6, then screw the limiting sleeve 9 into one end of the housing 1, and pass the cable 6 out from the middle of the rotating plate 12 to the outside. Then rotate the rotating ring 10 so that the multiple rotating plates 12 come together and limit the cable 6 in the middle position. Then blow air into any one of the air inlet slots 4 with a hot air gun. At this time, the hot air enters the air duct 5 through the air inlet slot 4 and flows around the heat shrink tube body 14. Under the influence of the Tesla valve effect formed by the guide slot 7 and the guide block 8, the hot air can stay in the air duct 5 as much as possible to heat the heat shrink tube body 14, thereby making the heat shrink tube body 14 produce a heat shrinking effect.
