[0022] Example 1

[0023] In order to prevent rain or dust from entering the connection position of the plug connector and the butt connector, the existing copper-containing photovoltaic cables also have protective components such as protective shells at the connection position of the plug connector and the butt connector for protection. This means that after the user completes the docking work of the plug connector and the butt connector, he needs to separately operate the installation and fixing work of the protective component, which is more troublesome and affects the construction efficiency of the photovoltaic cable. The following solution solves this problem.

[0024] See also Figures 1 to 5 A photovoltaic cable structure containing copper includes a plug connector 1 and a butt connector 2, wherein the plug connector 1 and the butt connector 2 are both fixedly connected with a cable body 3, the butt connector 2 is externally rotatably connected with a first rotating rod 4, the other end of the first rotating rod 4 is rotatably connected with a protective shell 11, and the connection between the plug connector 1 and the butt connector 2 is protected by the protective shell 11 to prevent the entry of dust and water; the inner side of the protective shell 11 is rotatably connected with a second rotating rod 5, the outer side of the second rotating rod 5 is rotatably connected with a connecting plate 6, the connecting plate 6 is fixedly connected to the butt connector 2, the inner side of the second rotating rod 5 is fixedly connected with a gear 7, and the outer side of the plug connector 1 is fixedly connected with a fixing plate 8, The outside of the fixed plate 8 is fixedly connected with a rack 9, which is used in conjunction with the gear 7. When the rack 9 is meshed with the gear 7, pushing and pulling the rack 9 can drive the second rotating rod 5 to rotate, thereby controlling the opening and closing of the two protective shells 11; the outside of the plug connector 1 is sleeved with an end cover 10, which is threadedly connected to the protective shell 11, and an internal thread is provided on the inner side of the end cover 10. The end cover 10 is sleeved on the outside of the plug connector 1 and can slide back and forth or rotate. The outer sides of the two protective shells 11 are provided with external threads, which match the internal threads on the inner side of the end cover 10. When the two protective shells 11 are assembled, the two protective shells 11 are fixed by sliding and screwing the end cover 10.

[0025] There are two first rotating rods 4, and the two first rotating rods 4 are symmetrically distributed. Correspondingly, there are also two protective shells 11 located on the outside of the docking joint 2. After the plug connector 1 and the docking joint 2 are docked, the two protective shells 11 are also spliced ​​together to protect the connection position model between the plug connector 1 and the docking joint 2.

[0026] The first rotating rod 4 and the second rotating rod 5 are of the same size. When the plug connector 1 and the docking connector 2 are docked, the second rotating rod 5 is driven to rotate through the gear 7 and the rack 9, and the first rotating rod 4 is also driven to rotate through the protective shell 11. Since the first rotating rod 4 and the second rotating rod 5 are of the same size and are parallel to each other, the protective shell 11 as a whole is always parallel to the docking connector 2. When the plug connector 1 and the docking connector 2 are docked, no gap will appear between the protective shell 11 and the plug connector 1 and the docking connector 2, thereby ensuring the sealing performance. The first rotating rod 4 and the second rotating rod 5 are both H-shaped structures, and the H-shaped second rotating rod 5 facilitates the installation of the gear 7.

[0027] A chamfer 12 is provided on the outer end of the rack 9 away from the fixing plate 8 , and the chamfer 12 facilitates the meshing of the rack 9 and the gear 7 when the plug connector 1 and the docking connector 2 are docked.

[0028] The steps of using the utility model are as follows: when the copper-containing photovoltaic cable structure is in use, the rack 9 on the plug connector 1 is inserted between the two connecting plates 6 on both sides of the second rotating rod 5, so that the rack 9 is meshed with the gear 7 inside the second rotating rod 5, and the second rotating rod 5 is driven to rotate by the rack 9 and the gear 7, and the second rotating rod 5 cooperates with the first rotating rod 4 to drive the protective shell 11 to move from the side away from the plug connector 1 to the side close to the plug connector 1, until the two protective shells 11 wrap the plug connector 1 and the docking connector 2 from both sides. At this time, the plug connector 1 and the docking connector 2 are docked, and the two protective shells 11 are also spliced. Finally, the spliced ​​protective shells 11 can be fixed by the end cover 10, and the connection between the plug connector 1 and the docking connector 2 is protected by the protective shell 11 to prevent rain or dust from entering, and the protective shell 11 can complete the protection operation when the plug connector 1 and the docking connector 2 are docked, instead of connecting and fixing the protective component separately after the plug connector 1 and the docking connector 2 are docked, which has fewer operation steps and saves more time.

[0029] Example 2

[0030] When the plug connector 1 and the docking connector 2 are docked, it is necessary to ensure that the rack 9 on the plug connector 1 can mesh with the gear 7 on the docking connector 2. Since the gear 7 and the protective shell 11 are on the same side, the user can ensure the meshing of the rack 9 and the gear 7 by aligning the positions of the rack 9 and the protective shell 11. Since the gear 7 is on the inner side of the protective shell 11, in order to prevent the protective shell 11 from blocking the line of sight, the problem is solved by the following solution.

[0031] See also Figure 5The difference between the basis of the combined implementation is that a fixing ring 13 is fixedly connected to the outside of the joint 2, and a through groove 14 is opened inside the fixing ring 13. The through groove 14 and the gear 7 are in the same straight line. The rack 9 will pass through the through groove 14 and then mesh with the gear 7. The fixing ring 13 and the through groove 14 mainly play the role of guiding the rack 9 to prevent the rack 9 from being misaligned with the gear 7.

[0032] The cross section of the through slot 14 is a trapezoidal structure. By utilizing the inclined surface of the trapezoidal structure, the rack 9 can more easily enter and pass through the through slot 14 and finally mesh with the gear 7 .

[0033] Steps for using the utility model: When the copper-containing photovoltaic cable structure is in use, the rack 9 will first enter the through groove 14 on the fixing ring 13 before meshing with the gear 7. The through groove 14 and the gear 7 are arranged on the same side and on the same straight line, until the rack 9 enters the through groove 14. Then, it can be ensured that the rack 9 is meshed with the gear 7, thereby avoiding the situation where the rack 9 and the gear 7 are misaligned.
