[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and achieve electromagnetic energy conversion.

[0025] The sealing connection mechanism includes an internal threaded tube 10, a sleeve 11, a third annular plate 12 and a sealing ring 13. The right end of the bellows 4 is fixedly sleeved inside the third annular plate 12, the sleeve 11 is fixedly connected to the right side of the third annular plate 12, the internal threaded tube 10 is rotatably sleeved on the right end outer wall of the sleeve 11, the left end outer wall of the protective tube 6 is threaded and sleeved with the inner wall thread of the internal threaded tube 10, the left end tube wall of the protective tube 6 is fixedly sleeved with a fourth annular plate 14, the sealing ring 13 is fixedly connected to the left side wall of the fourth annular plate 14 and is in contact with the right end face of the internal threaded tube 10. The sealing connection mechanism can be used to seal the connection between the first part 1 and the second part 2, thereby preventing water from entering.

[0026] The tube walls of the protective tube 6 and the internal threaded tube 10 are fixedly connected with a fixing plate 15, and a first through hole is opened inside the two fixing plates 15. The interiors of the two first through holes are jointly movably sleeved with a first limiting rod 16, and the rod wall of the first limiting rod 16 is fixedly sleeved with a first stopper 17. The right end of the first limiting rod 16 is fixedly connected with a hollow column 18, and the outer wall of the protective tube 6 is fixedly connected with a mounting plate 19, and a limiting hole is opened inside the mounting plate 19. A limiting mechanism is set inside the hollow column 18, and the limiting mechanism matches the limiting hole.

[0027] The limiting mechanism includes a second limiting rod 20. Second through holes are provided at both ends of the hollow column 18. The second limiting rod 20 is movably sleeved inside the hollow column 18 and the two second through holes. A second stopper 21 is movably sleeved inside the hollow column 18. The second stopper 21 is fixedly sleeved with the rod wall of the second limiting rod 20. The second limiting rod 20 matches the limiting hole. The baffle is used to prevent the second limiting rod 20 from separating from the hollow column 18.

[0028] The rod wall of the first limiting rod 16 is movably connected to a first spring 22, and the two ends of the first spring 22 are respectively fixedly connected to the first stopper 17 and the side wall of the corresponding fixed plate 15. By using the provided first spring 22, the first limiting rod 16 and the corresponding fixed plate 15 can be kept in an inserted state by the elastic force of the first spring 22.

[0029] The rod wall of the second limiting rod 20 is fixedly sleeved with a second spring 23, and the two ends of the second spring 23 are respectively fixedly connected to the second stop block 21 and the inner wall of the hollow column 18.

When it is necessary to seal the connection between the first part 1 and the second part 2, the second limit rod 20 is plugged into the limit hole, and the second limit rod 20 is limited by the elastic force of the second spring 23 to prevent the second limit rod 20 from separating from the limit hole, and the protective tube 6 is threadedly sleeved on the inside of the internal threaded tube 10. After the protective tube 6 and the internal threaded tube 10 are threadedly sleeved, the limit rod is removed from the inside of the limit hole, and the first spring 22 squeezes the first stopper 17 through its own elastic force, so that the first limit rod 16 is plugged into the first through hole inside the corresponding fixed plate 15, thereby preventing the connection between the protective tube 6 and the internal threaded tube 10 from loosening.
