Description

Technical Field

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

[0002] The photovoltaic junction box is a connection device between the solar cell array composed of solar cell modules and the solar charging control device. Its main function is to connect and protect solar photovoltaic modules, connect the power generated by solar cells to external lines, and conduct the current generated by photovoltaic modules. The photovoltaic junction box is usually installed on the back of the photovoltaic module, connects multiple photovoltaic modules through cables, and transmits power to the junction box or inverter.

[0003] For example, a Chinese patent disclosure: A photovoltaic junction box, application number: CN201120148046.X, includes a box body and a cable head rod cap, the box body is formed by connecting an upper box body and a lower box body, the front sides of the lower box body are provided with cable head rods, the cable head rods are connected to the cable head rod cap, and the inner wall of the connection between the cable head rod and the cable head rod cap is provided with a waterproof flower basket. The benefits of the utility model: the waterproof flower basket tightly blocks the gap and can prevent the photovoltaic cable from falling off, which is safe, reliable, convenient and practical.

[0004] However, in the above technical solution, the overall structure of the current photovoltaic junction box is relatively large, and the required installation space is relatively large. Therefore, it can only be installed in places with larger spaces, and cannot be installed in narrow locations. The scope of application is relatively narrow. In addition, in order to ensure the overall volume of the photovoltaic junction box, the outer wall surface of the cover of the photovoltaic junction box is usually parallel to the outer wall surface of the box body. This results in that when the inside of the box body needs to be inspected, it is inconvenient to take the cover because the outer wall surface of the cover is flush with the outer wall surface of the box body.
