[0002] The photovoltaic junction box is an important component of the photovoltaic power generation system. It is mainly used to connect and protect the electrical circuits inside the photovoltaic modules. At present, there are still some problems in the use of photovoltaic junction boxes. Due to the excessive number of terminal lines, if the wiring is not arranged and managed, it is easy to cause too many and messy lines, affecting the efficiency of line fault detection in the later stage. Line fault detection requires straightening out the messy lines one by one before effective fault detection can be carried out. The process is relatively troublesome. At the same time, the terminal lines on the photovoltaic junction box are affected by repeated pulling. At the least, the lines are too loose, affecting the line transmission stability. At worst, the pulling force is too strong, causing the lines to break, resulting in faults or transmission disconnection, thereby reducing the use effect of the photovoltaic junction box and indirectly affecting the transmission stability and durability of the photovoltaic junction box.

[0003] Therefore, it is necessary to develop a photovoltaic junction box. Utility Model Content
