[0002] The inexhaustible solar energy is being favored by more and more people. Solar photovoltaic power generation has been included in the new energy development and utilization plan by many countries, and the application volume is expanding year by year. The solar photovoltaic power generation system uses the photovoltaic effect of solar cell semiconductor materials , a new type of power generation system that directly converts solar radiation energy into electrical energy. In the electrical connection technology of solar power generation systems, solar photovoltaic junction boxes are usually used to realize the electrical connection between photovoltaic modules and inverters. The existing technology Middle: The patent of authorized publication number CN 208063126 U discloses a new solar photovoltaic junction box, which includes a junction box body, a lower cover, an upper cover and a cable fixing block, and one end of the junction box body is provided with two In the semicircular cable groove where the cables are placed, there is a cavity for accommodating the circuit module inside. The bottom surface of the cavity is provided with protrusions, and the lower cover is evenly distributed on the side opposite to the cavity. There are a plurality of fixing columns and glue injection holes for fixing the circuit module, at least two sides are provided with card slots that are engaged with the protrusions on the bottom surface of the cavity, and the four sides of the lower cover are engaged with the junction box body , the cable fixing block is provided with grooves arranged symmetrically with the cable groove, elastic clips on both sides that are snapped into the junction box body, and a glue injection hole on the top, which can only realize the box The rapid assembly of the body cannot realize the rapid installation of the circuit board, the sealing and waterproof performance is poor, there is no cable protection device, it is easy to scratch the cable skin, and rainwater penetrates into the photovoltaic junction box along the cable, causing potential safety hazards. Poor performance, for this reason, we propose a photovoltaic junction box that is easy to assemble to solve the above defects
