Screws 4 are provided in the screw grooves 3, and the protective block 2 is fixed to the wire end 10 at the lower end of the wire body 1 by the screws 4 extending into the screw grooves 3.

[0024] The lower end of the protective block 2 is detachably connected to an end block 7. Specifically, the bottom of the protective block 2 is an open structure, and a first slot is provided on the inner side of the bottom of the protective block 2. Threaded grooves 6 are provided on the left and right sides of the protective block 2 at positions corresponding to the first slot. The upper ends of the end block 7 are fixedly connected to second slots 8, and second slots 9 are provided in the second slots 8. The second slots 9 are provided with internal threads. The structure of the second slots 8 is adapted to the structure of the first slots. When the end block 7 is inserted from the bottom of the protective block 2, the second slots 8 are inserted into the first slots. At this time, the second slots 9 are connected to the threaded grooves 6. The threaded grooves 6 on the left and right sides of the protective block 2 are internally threaded with first slots 5. The first slots 5 are screwed into the second slots 9 to fix the protective block 2 and the end block 7.

[0025] An axial groove 16 is formed inside the end block 7. A second spring 17 is axially installed inside the groove 16. A connecting block 18 is movably connected inside the groove 16. The second spring 17 is connected between the connecting block 18 and the inner wall of the groove 16, and is sleeved on the outside of the connecting block 18. The connecting block 18 is a flexible, electrically conductive connecting wire. A second power line end block 19 is fixedly connected to the upper end of the connecting block 18. A transverse sliding groove 12 is formed at the top of the end block 7. A first spring 13 is transversely arranged inside the sliding groove 12. A slider 14 is slidably connected inside the sliding groove 12. The first spring 13 is connected between the slider 14 and the inner wall of the sliding groove 12. A scraper 15 is fixedly connected to the end of the slider 14 near the second power line end block 19. Specifically, the cross-sections of the first power cord end block 11, the scraper block 15, and the second power cord end block 19 are all circular, and the lower end of the first power cord end block 11 is a bevel. One end of the scraper block 15 and the second power cord end block 19 is a bevel, and the front end of the scraper block 15 is rough. The first power cord end block 11 is used to connect with the second power cord end block 19.

[0026] Specifically, in order to improve the sealing performance of the connection, sealing gaskets 21 are provided at the upper and lower ends of the protective block 2. The sealing gaskets 21 are heat-resistant polytetrafluoroethylene-lined metal composite gaskets.

[0027] The method of using the quick-release device for electrical connection terminals proposed in this embodiment is as follows: When in use, first put a set of sealing gaskets 21 on the line body 1, then put the protective block 2 on the wire end 10 at the bottom of the line body 1, then turn the screw 4 to make the inner wall of the protective block 2 fit tightly against the outer wall of the wire end 10. After the protective block 2 is firmly fixed on the line body 1, slide the sealing gasket 21 down and lock it on the upper outer wall of the protective block 2. Then, the end block 7 is pushed into the protective block 2 from bottom to top. When the first power line end block 11 at the lower end of the wire end 10 contacts the scraper block 15, friction is generated between the two surfaces. The oxide material on the lower surface of the first power line end block 11 is removed. Under the resistance of the first power line end block 11, the scraper block 15 pushes the slider 14 to slide away from the first power line end block 11. The first spring 13 is compressed. When the scraper block 15 slides completely into the groove 12, the second spring 17 rebounds and pushes the second power line end block 19 upward, so that the connecting block 18 is straightened, causing the second power line end block 19 to fit with the first power line end block 11, and the power is connected. When the threaded groove 6 is aligned with the second slot 9, screw the first locking block 5 into the second slot 9 to fix the end block 7 to the protective block 2. Finally, put the other set of sealing gaskets 21 on the lower end of the protective block 2. When the end needs to be replaced, simply pull out the first locking block 5 and then pull down the end block 7 to remove and replace it.
