Description

Technical Field

[0001] This utility model relates to the field of photovoltaic junction box technology, and in particular to a junction box used for photovoltaic curtain wall assembly. Background Technology

[0002] In the current development of natural energy technology, solar energy accounts for a large proportion of natural energy supply. Photovoltaic panels absorb sunlight and convert it into electricity. Currently, photovoltaic panels are used in many regions, especially in areas with long hours of sunshine. Large-scale installation of photovoltaic panels enables high-power generation. Solar photovoltaic power generation directly converts sunlight into electricity. Although photovoltaic power generation has applications across various industries, its greatest impact is on the building materials and construction sector. In the 1990s, with the rising cost of conventional power generation and increasing emphasis on environmental protection, some countries began to use rapidly decreasing-priced solar energy in buildings. Solar cells can now be bent and rolled up, with a thickness of only a few wavelengths, making them easy to cut, install, weatherproof, clean, and safe. They can replace architectural paints, ceramic tiles, and expensive curtain wall glass, serving as an external cladding material for energy-efficient walls.

[0003] When assembling a photovoltaic curtain wall, junction boxes are required. To ensure aesthetics, traditional junction boxes are often installed on the back side of the photovoltaic curtain wall, that is, between the photovoltaic curtain wall and the building wall. This structure is not conducive to the fixed assembly of the photovoltaic curtain wall, and due to the narrow space between the photovoltaic curtain wall and the building wall, there are problems with installation.

[0004] Therefore, in view of the shortcomings of existing technologies, it is necessary to design junction boxes for photovoltaic curtain wall assembly to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a junction box for photovoltaic curtain wall assembly.

[0006] To achieve the above and other related objectives, the technical solution provided by this utility model is: a junction box for photovoltaic curtain wall assembly, comprising a box body and a box cover, wherein the box cover is sealed at the top opening of the box body, and the bottom side wall of the box body extends outward to form a snap-on plate, the snap-on plate being configured to snap into the gap between the photovoltaic module and the curtain wall.

[0007] The preferred technical solution is that a waterproof sealing ring is embedded in the top opening of the box.

[0008] A preferred technical solution is that the housing is provided with positioning posts for positioning diodes.

[0009] The preferred technical solution is that the box cover is provided with an inspection port, and a detachable inspection cover is fastened to the inspection port.

[0010] The preferred technical solution is as follows: the inner wall of the box cover is provided with multiple sets of support protrusions for supporting the inspection cover, the inner ring of the inspection port is provided with a buckle, and the edge of the inspection cover is provided with a slot, the slot and the buckle are correspondingly matched.

[0011] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0012] The junction box for photovoltaic curtain wall assembly provided by this utility model solves the problem of difficult junction box assembly due to the narrow space between the photovoltaic curtain wall and the building wall by setting an outwardly extending buckle plate at the bottom of the side wall of the box. The buckle plate is configured to be snapped into the gap between the photovoltaic module and the curtain wall. This structure can greatly improve the assembly efficiency of photovoltaic curtain walls. Attached Figure Description
