[0002] Photovoltaic panels are a type of power generation component that can convert light into electricity. They are a type of clean energy and are suitable for outdoor use.

[0003] When installing photovoltaic panels outdoors, the panels are arranged in a certain order and then connected to adjacent panels via connecting wires and junction boxes. This allows multiple groups of photovoltaic panels to be organized into one place for centralized power generation. Adjacent photovoltaic panels are electrically connected via connecting wires and connectors. However, since there is no structure to help fix the junction box assembly, when connecting the photovoltaic panel lines, the connectors are easily located in the gaps between adjacent photovoltaic panels. In this case, rainwater will fall on the outside of the connectors, and even if the connectors are sealed, long-term corrosion can cause internal corrosion and short circuits.

[0004] Therefore, there is an urgent need for a waterproof and dustproof photovoltaic solar panel junction box assembly to solve the above problems. Utility Model Content

[0012] Furthermore, the outer surface of the connecting line is slidably connected to the interior of both the first and second fixed cylinders, and both the first and second fixed cylinders are connected by a connecting ring.

[0013] Furthermore, a positioning rod is fixedly installed on the outer surface of the first fixed cylinder, and the outer surface of the positioning rod is slidably connected to the inside of the second fixed cylinder.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a waterproof and dustproof photovoltaic solar panel junction box assembly, including a mounting frame 1 and a photovoltaic panel 2. A junction box 3 is installed on the outside of the photovoltaic panel 2, and a connecting wire 4 is connected inside the junction box 3. A connector 5 is installed on the outside of the connecting wire 4. Adjacent photovoltaic panels 2 are connected through connectors 5 and connecting wires 4. Adjacent connectors 5 are connected by plug-in connection. The photovoltaic panel 2 can be fixed to the outside of the mounting frame 1 by pressing and fixing parts. At this time, there is an installation gap between the upper and lower adjacent photovoltaic panels 2. Then, the adjacent photovoltaic panels 2 are connected through the junction box 3 and connectors 5.

[0025] A mounting bracket 6 is slidably connected to the outside of the photovoltaic panel 2. A clamping plate 7 is fixedly installed on the outer surface of the mounting bracket 6. The mounting bracket 6 has a U-shaped structure, and the clamping plate 7 is located at both ends of the mounting bracket 6. Both sides of the mounting bracket 6 are elastic plate structures that can clamp the outside of the photovoltaic panel 2. The two side walls of the mounting bracket 6 can be clamped towards the middle. Anti-slip rubber strips are installed on both side walls of the mounting bracket 6 to improve the stability during fixing. During installation, the mounting bracket 6 can be directly clamped to the outside of the adjacent photovoltaic panel 2. At this time, the clamping plate 7 can limit one end of the mounting bracket 6.

[0026] The mounting plate 8 is slidably connected inside the fixing frame 6. A movable plate 9 is fixedly installed at one end of the mounting plate 8. A fixing bolt 11 is threaded inside the fixing frame 6. The fixing bolt 11 is located at the bottom of the fixing frame 6. One end of the fixing bolt 11 is in contact with the outer surface of the mounting plate 8. By rotating the fixing bolt 11, one end of the fixing bolt 11 can be controlled to press against the outer surface of the mounting plate 8. At this time, the position of the mounting plate 8 is fixed. The fixing bolt 11 can control the mounting plate 8 to be fixed. Conversely, the position of the mounting plate 8 can be adjusted.

[0027] A first fixing cylinder 10 is fixedly installed on the outer surface of the movable plate 9. A second fixing cylinder 12 is slidably connected to the outer surface of the first fixing cylinder 10. A positioning rod 14 is fixedly installed on the outer surface of the first fixing cylinder 10. The outer surface of the positioning rod 14 is slidably connected to the inside of the second fixing cylinder 12. Multiple sets of positioning rods 14 are installed on the side where the first fixing cylinder 10 and the second fixing cylinder 12 contact each other. At this time, the first fixing cylinder 10 and the second fixing cylinder 12 can be quickly connected and installed. After the first fixing cylinder 10 and the second fixing cylinder 12 are connected, sealant should be applied to the contact position to increase the waterproof and dustproof effect.

[0028] The outer surface of the connecting wire 4 is slidably connected to the inside of the first fixing cylinder 10 and the second fixing cylinder 12. The first fixing cylinder 10 and the second fixing cylinder 12 are connected by the connecting ring 13. When the first fixing cylinder 10 and the second fixing cylinder 12 are installed, they are located on one side of the fixing frame 6. The connector 5 is located inside the first fixing cylinder 10 and the second fixing cylinder 12. The connector 5 can be installed inside the first fixing cylinder 10 and the second fixing cylinder 12 by closing left and right. At this time, there should be rubber rings on both ends of the first fixing cylinder 10 and the second fixing cylinder 12 to seal the openings of the connecting wire 4. When the connecting wire 4 is fixed, it can be bent near both ends of the first fixing cylinder 10 and the second fixing cylinder 12. At this time, rainwater is not easy to fall directly to the outside from the connecting wire. When the overall fixing frame 6 is installed, it is in an inclined structure along with the photovoltaic panel 2.

[0029] Both the outer surfaces of the first fixed cylinder 10 and the second fixed cylinder 12 are threaded with connecting rings 13. The connecting rings 13 can press and fix the first fixed cylinder 10 and the second fixed cylinder 12, resulting in higher reliability of the threaded connection and greater stability during use.

[0030] Working principle: During installation, the mounting bracket 6 is first clamped between adjacent photovoltaic panels 2. Then, the two fixing cylinders 10 and 12 are moved to fix the connector 5 inside. At this time, the fixing cylinders 10 and 12 are connected and fixed by the connecting ring 13. Then, the mounting plate 8 is moved inside the mounting bracket 6, and the fixing cylinders 10 and 12 are moved away from the gap between adjacent photovoltaic panels 2. The fixing bolt 11 is rotated so that one end of the fixing bolt 11 is pressed against the mounting plate 8. At this time, the mounting plate 8 is fixed, and external rainwater will not fall directly on the outside of the connector 5.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
