[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution for an anti-detachment photovoltaic cable connection structure:
[0022] Embodiment 1:
[0023] As Figures 1-3 shown, an anti-detachment photovoltaic cable connection structure includes two connecting sleeves 1. Two compression sleeves 2 are sleeved on one end of each of the two connecting sleeves 1. Support rods 3 are arranged inside each of the two connecting sleeves 1.

Among them, wrapping sleeves 12 are sleeved on one end of each of the two compression sleeves 2, enhancing the stability of the connection between the first photovoltaic cable component 16 and the second photovoltaic cable component 17. After the L-shaped plate 13 and the binding plate 14 are mutually attached, the two are fixed by using the limiting bolt 15, further strengthening the firmness of the installation of the two protective sleeves 7 and improving the anti-detachment performance of the connection structure.
[0024] Embodiment 2:
[0025] On the basis of Embodiment 1, as Figure 1 and Figure 4As shown in the figure, a second circular sleeve 11 is provided on one side of one of the first circular sleeves 10. The second circular sleeve 11 is snap-connected to another first circular sleeve 10. The two L-shaped plates 13 and the two binding plates 14 are respectively connected by a limit bolt 15 in a threaded manner. A first photovoltaic cable member 16 is provided inside one of the connecting sleeves 1, and a second photovoltaic cable member 17 is provided inside the other connecting sleeve 1. For an anti-detachment photovoltaic cable connection structure of the present utility model, by providing a positioning rod 5, a limit ring 6, a compression rib 8 and a second circular sleeve 11, reversely rotating the limit ring 6 to disassemble the limit ring 6 from the positioning rod 5, so that the protective sleeve 7 can be pulled out from one end of the positioning rod 5. Therefore, as the support block 4 moves, the protective sleeve 7 will move accordingly. The protective sleeve 7 and the sealing sleeve 9 are connected by a plurality of compression ribs 8.
[0026] Working principle: Photovoltaic cables are special cables used to connect photovoltaic modules with inverters and power distribution systems. They play a crucial role in the photovoltaic system, ensuring the transmission of electricity and the reliable operation of the system. Photovoltaic cables need to have good weather resistance to resist sunlight, ultraviolet rays, and rain. The outer sheath of photovoltaic cables is made of special materials that are resistant to ultraviolet rays, high temperatures, and cold. Photovoltaic cables are connected in parallel to increase the current and ensure that multiple modules work together. The connection structure can mainly connect between two photovoltaic cables. Therefore, the sealing effect of the connection structure on the outer surface of the photovoltaic cable needs to be improved. When the photovoltaic cable is working, in order to avoid loosening and affecting normal operation, the connection structure needs to have a good anti-detachment effect. Therefore, it is particularly important to design an anti-detachment connection structure for photovoltaic cables. First, two connecting sleeves 1 are respectively sleeved on one end of the first photovoltaic cable part 16 and the second photovoltaic cable part 17. The support block 4 can move back and forth at one end of the support rod 3, so that the distance between the two protective sleeves 7 can be adjusted. The two connecting sleeves 1 can respectively wrap the first photovoltaic cable part 16 and the second photovoltaic cable part 17. The first photovoltaic cable part 16 and the second photovoltaic cable part 17 can be connected through the fixation of the protective sleeves 7. After the two protective sleeves 7 move relatively, they drive the first circular sleeve 10 and the second circular sleeve 11 to approach each other. After the first circular sleeve 10 and the second circular sleeve 11 are engaged, the outer surfaces of the first photovoltaic cable part 16 and the second photovoltaic cable part 17 can be covered and sealed, enhancing the stability of the connection between the first photovoltaic cable part 16 and the second photovoltaic cable part 17. After the L-shaped plate 13 and the binding plate 14 are mutually attached, the two are fixed by using the limit bolt 15, further strengthening the stability of the installation of the two protective sleeves 7 and improving the anti-detachment performance of the connection structure. Rotate the limit ring 6 in the reverse direction to disassemble the limit ring 6 from the positioning rod 5, so that the protective sleeve 7 can be pulled out from one end of the positioning rod 5. Therefore, as the support block 4 moves, the protective sleeve 7 will move accordingly. The protective sleeve 7 and the sealing sleeve 9 are connected by a plurality of compression ribs 8. Under the connection of the compression ribs 8, the sealing sleeve 9 and the first circular sleeve 10 will be driven to move synchronously. The second circular sleeve 11 will gradually be embedded into the inside of another first circular sleeve 10, and the two are engaged with each other. Through the coverage of the two sealing sleeves 9, the two first circular sleeves 10, and the second circular sleeve 11 on the first photovoltaic cable part 16 and the second photovoltaic cable part 17, the sealing performance of the wrapping of the first photovoltaic cable part 16 and the second photovoltaic cable part 17 is enhanced.
