[0002] A photovoltaic junction box is a connecting device between a solar cell array composed of solar cell modules and a solar charging control device. Its main function is to connect and protect the solar photovoltaic modules, connect the electricity generated by the solar cells to the external circuit, and conduct the current generated by the photovoltaic modules.

[0003] At present, the photovoltaic junction box is adhered to the photovoltaic panel through silicone during installation. The photovoltaic junction box is exposed outdoors for a long time and needs to withstand the influence of weather such as wind, rain, high temperature, and cold, resulting in easy damage to the photovoltaic junction box and the need for replacement or repair. Usually, when replacing the junction box, it is necessary to first remove the adhered glue, which takes a long time and is likely to cause scratches or damage to the photovoltaic panel, making disassembly and assembly inconvenient. Therefore, the applicant has developed a solar photovoltaic junction box adopting a movable pressing type installation during the actual production process to solve the above technical problems.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] A solar photovoltaic junction box using a movable pressing type installation, as Figure 1 and Figure 2 and Figure 3 , includes a photovoltaic panel 1, a junction box body 2, and a frame 3 for installing the photovoltaic panel 1. Two slideways 4 distributed up and down are provided at the rear side of the frame 3, and the two slideways 4 are parallel. A sliding plate 5 is horizontally slidably connected between the two slideways 4. The junction box body 2 is located between the photovoltaic panel 1 and the sliding plate 5 and is within the frame 3. A pressing mechanism for pressing the junction box body 2 against the photovoltaic panel 1 is provided on the sliding plate 5. A gasket 6 that abuts against the photovoltaic panel 1 is provided on one side of the junction box body 2 close to the photovoltaic panel 1. A first limiting member for restricting the sliding of the sliding plate 5 on the slideway 4 is provided on the upper slideway 4.

[0033] Such as Figure 1 and Figure 2 andFigure 3 When in use, install the two slides 4 on the rear side of the frame 3, then place the junction box body 2 at the position where the photovoltaic panel 1 needs to be installed, then connect the photovoltaic panel 1 to the junction box body 2, and then slide the slide plate 5 to the junction box body 2. At this time, the junction box body 2 is located between the slide plate 5 and the photovoltaic panel 1, and then the junction box body 2 is pressed against the photovoltaic panel 1 by the clamping mechanism, so that the sealing gasket 6 is pressed against the photovoltaic panel 1, and then the slide plate 5 is restricted by the first limiting member so that it cannot slide on the slide plate 4. At this time, the junction box body 2 can be installed on the photovoltaic panel 1. The disassembly and assembly are simple and convenient, and there is no need to adhere the junction box body 2 to the photovoltaic panel 1 through silicone, which improves environmental protection.

[0034] like Figure 3 and Figure 4 and Figure 5 The clamping mechanism includes a moving plate 7 and a rectangular groove 8 opened on the side of the slide plate 5 away from the junction box body 2. One end of the moving plate 7 passes horizontally through the rectangular groove 8 and is provided with a pressing plate 9. The side of the pressing plate 9 away from the moving plate 7 is provided with an embedding groove 10. The end of the junction box body 2 away from the photovoltaic panel 1 is embedded in the embedding groove 10 and contacts the bottom of the embedding groove 10. The side of the slide plate 5 away from the photovoltaic panel 1 is provided with a bracket 12, and the bracket 12 is located below the moving plate 7. The bracket 12 is provided with a pushing member for pushing the moving plate 7 to move toward the photovoltaic panel 1.

[0035] like Figure 3 and Figure 4 and Figure 5 When the junction box body 2 is located between the slide plate 5 and the photovoltaic panel 1, the embedding groove 10 on the pressure plate 9 will correspond to the junction box body 2. At this time, the movable plate 7 is pushed to move toward the photovoltaic panel 1, so that the end of the junction box body 2 away from the photovoltaic panel 1 enters the embedding groove 10 and contacts the bottom of the embedding groove 10. Then, the movable plate 7 is pushed by the pushing member to continue to move toward the photovoltaic panel 1 until the sealing gasket 6 on the junction box body 2 is pressed against the photovoltaic panel 1. The installation and disassembly are simple.

[0036] like Figure 4, the first limiting member includes a plurality of jacks 13 provided on the upper slideway 4, and the jacks 13 are spaced apart along the length direction of the slideway 4. The top end of the moving plate 7 is provided with an inverted L-shaped insertion post 14, and the horizontal part of the insertion post 14 away from the moving plate 7 is inserted into one of the jacks 13. The purpose of this setting is that when the junction box body 2 is located between the sliding plate 5 and the photovoltaic panel 1, and the embedding groove 10 on the pressing plate 9 corresponds to the junction box body 2, the insertion post 14 will correspond to one of the jacks 13. When the moving plate 7 moves towards the photovoltaic panel 1, the moving plate 7 will drive the insertion post 14 to move. When, with the movement of the moving plate 7, the gasket 6 on the junction box body 2 is pressed tightly on the photovoltaic panel 1, the end of the insertion post 14 away from the moving plate 7 will be inserted into the corresponding jack 13. At this time, through the cooperation of the insertion post 14 and the jack 13, the sliding plate 5 can be restricted so that it cannot slide on the slideway 4.

[0037] As Figure 5 , the pushing member includes a rotating shaft 15 provided at the top end of the bracket 12, and an eccentric wheel 16 is rotatably connected to the rotating shaft 15. One end of the arc surface of the eccentric wheel 16 contacts the side of the moving plate 7 away from the pressing plate 9. A rotating rod 17 is provided at the end of the eccentric wheel 16 away from the rotating shaft 15. A second limiting member for restricting the movement of the moving plate 7 through the rectangular groove 8 is provided on the bracket 12. The purpose of this setting is that when it is necessary to push the moving plate 7 towards the photovoltaic panel 1, only need to drive the eccentric wheel 16 to rotate on the rotating shaft 15 through the rotating rod 17. At this time, the eccentric wheel 16 on the rotating shaft 15 can push the moving plate 7 towards the photovoltaic panel 1. When, with the movement of the moving plate 7, the gasket 6 on the junction box body 2 is pressed tightly on the photovoltaic panel 1, the moving plate 7 can be restricted by the second limiting member so that it cannot move.

[0038] As Figure 3 and Figure 5 and Figure 6 and Figure 7, the second limiting member includes a first fixing plate 18 disposed inside the bracket 12 near one side of the sliding plate 5, and a first vertical groove 19, a first communication groove 20, a first circular groove 21, and a first placement groove 22 disposed on the side of the first fixing plate 18 facing away from the sliding plate 5. The first vertical groove 19 communicates with the top end of the first fixing plate 18. The first circular groove 21 is located on one side of the first vertical groove 19. Both the first communication groove 20 and the first placement groove 22 are located between the first circular groove 21 and the first vertical groove 19. The first communication groove 20 communicates with the first circular groove 21 and the first vertical groove 19. The first placement groove 22 is located below the first communication groove 20 and communicates with the first communication groove 20. A first insertion plate 23 is vertically and slidably connected in the first vertical groove 19. A first insertion slot 24 for vertically inserting the top end of the first insertion plate 23 is provided at the bottom end of the moving plate 7. A first push plate 25 is horizontally provided on one side of the first insertion plate 23 close to the first communication groove 20. And the end of the first push plate 25 away from the first insertion plate 23 horizontally extends into the first circular groove 21 through the first communication groove 20. A first compression spring 26 is provided at one end of the first push plate 25 close to the first placement groove 22. And the end of the first compression spring 26 away from the first push plate 25 is located in the first placement groove 22 and fixedly connected to the bottom groove wall of the first placement groove 22. A first cover plate 27 is provided on the first fixing plate 18. And the first cover plate 27 is used to close the openings of the first vertical groove 19, the first communication groove 20, the first circular groove 21, and the first placement groove 22. A first unlocking member for pushing the first push plate 25 in the first circular groove 21 to move downward is provided on the first fixing plate 18.

[0039] As Figure 3 and Figure 5 and Figure 6 and Figure 7 , when the rotating rod 17 drives the eccentric wheel 16 to rotate on the rotating shaft 15, so that the moving plate 7 approaches the junction box body 2 until the gasket 6 on the junction box body 2 is pressed tightly on the photovoltaic panel 1, the first insertion slot 24 on the moving plate 7 will correspond to the first vertical groove 19. At this time, the first compression spring 26 will push the first push plate 25 to move upward, and the first push plate 25 will push the first insertion plate 23 to move upward until the top end of the first insertion plate 23 is inserted into the first insertion slot 24. At this time, through the cooperation of the first insertion slot 24, the first insertion plate 23, and the first vertical groove 19, the moving plate 7 can be restricted and cannot move;

[0040] When the junction box body 2 needs to be replaced, only need to push the first push plate 25 in the first circular groove 21 downward through the first unlocking member until the first insertion plate 23 is separated from the first insertion slot 24, and then pull the moving plate 7 away from the junction box body 2 until the junction box body 2 is separated from the embedding groove 10 on the pressing plate 9, and then slide the sliding plate 5 to be misaligned with the junction box body 2, and then replace the junction box body 2, and the disassembly and assembly are simple.

[0041] As Figure 6and Figure 7 , the first unlocking member includes a first cylinder 28 and two first baffles 29 arranged on the wall of the first circular groove 21. The two first baffles 29 are opposite to each other up and down, and a first side groove 30 is formed on one side of the upper first baffle 29. The first side groove 30 communicates with the bottom end of the first baffle 29. A first circular hole 31 coaxial with the first circular groove 21 is formed on the first cover plate 27. The first cylinder 28 is horizontal and one end of the first cylinder 28 passes through the first circular hole 31 and contacts the bottom of the first circular groove 21. A first rotating plate 32 is arranged on the side of the first cylinder 28 away from the bottom of the first circular groove 21. A first shifting lever 33 located in the first circular groove 21 is arranged on the side of the first cylinder 28 away from the first push plate 25. A first long strip groove 34 communicating with the first circular hole 31 is formed on the first cover plate 27, and the first long strip groove 34 corresponds to the first shifting lever 33. When the first cylinder 28 rotates clockwise, the first shifting lever 33 passes through the first side groove 30. The first cylinder 28, the first shifting lever 33 and the first rotating plate 32 form a first key 35. The first long strip groove 34 and the first circular hole 31 form a first keyhole 36 for the first cylinder 28 and the first shifting lever 33 to insert into the first circular groove 21.

[0042] As Figure 6 and Figure 7 , when it is necessary to push the first push plate 25 in the first circular groove 21 downward, only need to insert the first cylinder 28 and the first shifting lever 33 in the first key 35 into the first circular groove 21 from the first keyhole 36, and then rotate the first key 35 clockwise, so that the first shifting lever 33 passes through the first side groove 30 and contacts the top end of the first push plate 25, and then continue to rotate the first key 35 clockwise. At this time, the first shifting lever 33 will push the first push plate 25 downward. Through the cooperation of the first key 35 and the first keyhole 36, the situation that the junction box body 2 is lost or stolen can be reduced, and the use is simple and convenient.

[0043] As Figure 5 and Figure 8The top of the eccentric wheel 16 is provided with a through hole 37, and the through hole 37 is located at the end of the eccentric wheel 16 away from the rotating shaft 15. The top of the bracket 12 is provided with a threaded hole 38 corresponding to the through hole 37. The threaded hole 38 is internally threaded with a screw 39, and the top of the screw 39 passes through the through hole 37 and is provided with a nut 40 located outside the through hole 37. The purpose of this arrangement is that when the rotating rod 17 drives the eccentric wheel 16 to rotate on the rotating shaft 15, so that the moving plate 7 approaches the junction box body 2 until the sealing gasket 6 on the junction box body 2 is pressed against the photovoltaic panel 1, the through hole 37 on the eccentric wheel 16 will be in contact with the threaded hole 38. The eccentric wheel 16 can be restricted so that it cannot rotate by inserting the screw 39 into the through hole 37 and screwing one end of the screw 39 into the threaded hole 38. At this time, the movable plate 7 can be further restricted by the eccentric wheel 16, reducing the insertion of the first plug plate 23 into the first slot 24. When the eccentric wheel 16 is released, there is a gap between the groove wall of the first slot 24 close to the pressure plate 9 and the first plug plate 23, which causes the sealing gasket 6 on the junction box body 2 to be pressed against the photovoltaic panel 1. The outer wall of the screw 39 is wrapped with raw tape.
