Technical Field

[0001] The utility model relates to the technical field of photovoltaic wiring components, in particular to a photovoltaic wiring component. Background Art

[0002] Photovoltaics is a new form of power generation that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. In a photovoltaic power generation system, photovoltaic wiring assemblies are needed to connect the electricity generated by solar cells to external circuits to conduct the current generated by photovoltaic assemblies.

[0003] As disclosed in the Chinese patent: A photovoltaic junction box and a three-part photovoltaic junction assembly, application number: CN202021539287.2, the photovoltaic junction box includes a box body, which is provided with a receiving space; a first copper sheet, which is arranged in the receiving space, and a first welding point is arranged at one end of the first copper sheet; a second copper sheet, which is arranged in the receiving space, and a second welding point is arranged at one end of the second copper sheet; a diode, whose two ends are respectively welded to the other end of the first copper sheet and the other end of the second copper sheet, wherein the first welding point and the second welding point are located on one side, the diode is located on the other side, and there is a gap between the first copper sheet and the second copper sheet. By arranging the first welding point and the second welding point of the photovoltaic junction box on one side, the wiring of the photovoltaic junction box is convenient.

[0004] However, in the above technical solution, in the photovoltaic power generation system, it is necessary to use photovoltaic wiring assemblies to connect the electricity generated by the solar cells to the external lines. Photovoltaic power generation systems are mostly set up in the wild in harsh environments and are often affected by wind. In particular, the connecting wires on the photovoltaic wiring assemblies are easily blown by the wind and shake continuously. Once the shaking amplitude is too large, it is easy to cause the outer protective layer of the connecting wire to be damaged, and even the internal structure of the cable to be damaged, further affecting the service life and stability of the cable, and even causing safety hazards.

In particular, the connecting wires on the photovoltaic wiring assembly are easily blown by the wind and shake constantly. Once the shaking amplitude is too large, it is easy to cause the outer protective layer of the connecting wire to be damaged, and even the internal structure of the cable can be damaged, further affecting the service life and stability of the cable, and even causing safety hazards.

[0027] like Figures 3 to 5 As shown, in another embodiment of the present invention, the positioning tube 6 includes a positioning tube base 601, and a telescopic sleeve 602 is slidably arranged in the inner cavity of the positioning tube base 601;

[0028] The outer wall of the positioning tube base 601 is rotatably provided with a rotating ring 603, and the inner wall of the rotating ring 603 is provided with two grooves 604;

[0029] The inner wall of the positioning tube base 601 is provided with two slide grooves 605, and an insert block 606 is slidably arranged in the slide groove 605. A pressure plate 607 is arranged on both sides of the insert block 606, and a spring 608 is fixedly arranged on the outer wall of one side of the pressure plate 607;

[0030] The outer wall of the telescopic sleeve 602 is provided with a plurality of slots 609, and the inner wall of the telescopic sleeve 602 on the side away from the wiring hole 4 is provided with a plurality of balls 6010. When it is necessary to limit the connection wire 5 to prevent the connection wire 5 from shaking too much, the telescopic sleeve 602 is first extended, and the exposed part of the connection wire 5 is shielded and limited by the telescopic sleeve 602. When it is necessary to fix the position of the telescopic sleeve 602, the rotating ring 603 is rotated to gradually separate the groove 604 on the rotating ring 603 from the plug block 606, and then the outer wall surface of the rotating ring 603 squeezes the semicircular plug block 606. On one side, the plug block 606 moves toward the slot 609, the pressure plate 607 moves with the plug block 606, the spring 608 contracts, and finally one end of the plug block 606 is inserted into the slot 609, thereby fixing the position of the telescopic sleeve 602, reducing the overall area of ​​the connecting wire 5 exposed to the outside, thereby reducing the area that can be affected by the wind, and then by reducing the area that can be affected by the wind, the shaking amplitude of the connecting wire 5 is reduced, and the ball 6010 is used to prevent the connecting wire 5 from contacting the outer wall of the telescopic sleeve 602 when shaking, thereby reducing the probability of wear of the connecting wire 5 due to contact with the outer wall of the telescopic sleeve 602.

[0032] When in use, first fit the fixed base plate 8 to the designated device, then fill the glue filling groove 9 with glue, so that the fixed base plate 8 is fixedly connected to the designated device by filling the glue, and then the negative box 1, the positive box 2 and the intermediate box 3 are connected to the designated device through the connecting wire 5. After the connection is completed, the telescopic sleeve 602 is extended, and the exposed part of the connecting wire 5 is shielded and limited by the telescopic sleeve 602. When the position of the telescopic sleeve 602 needs to be fixed, the rotating ring 603 is rotated to make the groove 604 on the rotating ring 603 gradually separate from the plug 606, and then the outer wall surface of the rotating ring 603 squeezes one side of the semicircular plug 606 to make the plug 606 move toward the slot 609 moves, the pressure plate 607 moves with the insertion block 606, the spring 608 contracts, and finally one end of the insertion block 606 is inserted into the slot 609, so as to fix the position of the telescopic sleeve 602, reduce the overall area of ​​the connecting wire 5 exposed to the outside, thereby reducing the area that can be affected by the wind, and then by reducing the area that can be affected by the wind, reduce the shaking amplitude of the connecting wire 5, and prevent the connecting wire 5 from contacting the outer wall of the telescopic sleeve 602 when shaking by the ball 6010, reduce the probability of the connecting wire 5 being worn due to contact with the outer wall of the telescopic sleeve 602, can effectively reduce the shaking amplitude of the connecting wire 5, and reduce the probability of damage to the connecting wire 5.
