Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes, in particular to a junction box. Background Art

[0002] Solar panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. The main material of most solar panels is "silicon", but due to the high production cost, its widespread use has certain limitations. Compared with ordinary batteries and rechargeable batteries, solar cells are more energy-saving and environmentally friendly green products. Solar panels usually include multiple silicon wafers, each of which has a negative electrode grid printed on the front and a positive electrode grid printed on the back. When assembling, the silicon wafers need to be fixed on the circuit board first, and then the silicone sheets are manually welded in series or parallel using welding tapes.

[0003] Since solar photovoltaic panels are generally installed in pieces, in order to prevent obstructions between photovoltaic panels, photovoltaic panels are installed in groups, and the number of photovoltaic panels in each group is different. In order to facilitate the installation and connection of the lines, this solution proposes a junction box. Utility Model Content
