Description

technical field [0001] The invention relates to the technical field of photovoltaic junction boxes, in particular to an axial diode junction box and a manufacturing method thereof. Background technique [0002] As the application of solar power generation becomes more and more common, the junction boxes closely related to its application are constantly being introduced. Solar power generation uses multiple groups of solar cell modules arranged in a matrix to convert sunlight into electrical energy. Each group of solar cell modules and junction boxes The junction box is connected with other parts of the solar power generation system. [0003] The diode is a key component in the photovoltaic cell junction box. During use, the diode will generate heat. If the heat is not dissipated in time, it will affect the life of the diode and fail to meet electrical safety requirements. Moreover, as the market demand for high-current photovoltaic junction boxes increases, more and more ma...
