Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic junction boxes, and particularly relates to a split-type photovoltaic junction box. Background Technique

[0002] The photovoltaic junction box is an important component of a solar module. Its main function is to connect the electricity generated by solar cells to external circuits. Most photovoltaic junction boxes are directly fixed at designated positions by screws during installation. During subsequent maintenance, the screws need to be removed to take the whole down, and after the maintenance is completed, the photovoltaic junction box is fixed again by screws. This makes the overall operation rather troublesome. To solve this problem, split-type photovoltaic junction boxes are now used, which facilitates the disassembly and installation of the junction box in the later stage.

[0003] Chinese Patent with the publication number of "CN215072316U" discloses a split-type photovoltaic junction box, which includes a photovoltaic junction box body and a mounting plate for mounting the photovoltaic junction box body. A plurality of flat head screws for connecting to mounting points are connected to the side of the mounting plate. A support plate for supporting the photovoltaic junction box body is arranged on the side of the mounting plate. Heat dissipation components for assisting in dissipating heat from the photovoltaic installation box body are arranged on both sides of the support plate. A fixing component for fixing the photovoltaic junction box body is movably installed at the top of the heat dissipation components.

[0004] However, there are some deficiencies in the structure of this junction box. When fixing the junction box, the user needs to first place the junction box on the top of the support plate, and then use the limiting piece at its top to perform secondary positioning on the position of the junction box. When it is necessary to disassemble the junction box, the user also needs to open the limiting piece and then pull out the junction box in the reverse way. This back-and-forth disassembly and assembly method will greatly increase the wear degree of the installation points of the junction box, and thus reduce the service life of the installation structure of the junction box.

The anti-slip layer on the rear side of the mounting plate 1 covers the mounting plate 1. Due to the opening of the positioning holes 22, the position of the mounting plate 1 can be fixed through positioning parts that match the positioning holes 22. The anti-slip layer is an anti-slip coating, which can effectively improve the anti-slip ability of the rear side of the mounting plate 1, thereby improving the stability of the fixed position of the mounting plate 1.

[0033] Principle of use and advantages: When fixing the mounting plate 1, a positioning member matching the positioning hole 22 can be used to effectively fix the position of the mounting plate 1. When installing the junction box body 3, the junction box body 3 can be directly slid into the inner side of the limiting plate 12 through the first chute 2. Its support block 5 can effectively support the bottom end of the junction box body 3. Then, by pressing the spring buckle 20, the baffle 21 can be extended outward to limit the top end of the junction box body 3. When disassembling the junction box body 3, the second block 15 is screwed to a position symmetrical to the second slot 9, and then the first block 14 is directly pulled out of the first slot 8, and then the support block 5 can be disassembled. The junction box body 3 can be directly pulled out in a way that it moves downward along the mounting plate 1. While improving the disassembly and assembly efficiency of the junction box body 3, it also effectively reduces the wear degree of the installation structure of the junction box body 3, and thus can improve the service life of the disassembly and assembly structure of the junction box body 3. Due to the existence of the limiting block 6, the insertion of the limiting block 6 can effectively limit the position of the support block 5, while improving the fixing stability of the position of the support block 5, it can also effectively improve the accuracy of the clamping of the first block 14. Due to the existence of the first protection plate 41 and the second protection plate 45, the front side of the junction box body 3 can be effectively protected, and thus the junction box body 3 can be prevented from being knocked. The opening of the ventilation port 42 is conducive to the ventilation and heat dissipation of the junction box body 3. Its aluminum strip 43 is made of aluminum and has good heat dissipation ability, and at the same time can effectively protect the inner side of the ventilation port 42, and thus can effectively improve the service life of the junction box body 3. Due to the opening of the rectangular opening 47, the user can directly view the face of the junction box body 3 through the transparent glass 48 without disassembling the second protection plate 45, so it is conducive for the user to observe the condition of the junction box body 3 at all times, thereby improving the safety of the junction box body 3.
