Bypass element module of photovoltaic module and split type photovoltaic module junction box with same

Abstract

The invention provides a bypass element module of a photovoltaic module. The bypass element module comprises a first conductive terminal, a second conductive terminal and an insulating plastic package block, wherein a bypass protection device, the first conductive terminal and the second conductive terminal are packaged into a whole by the insulating plastic package block; bus bar through holes and flanging structures are formed in the first conductive terminals and the second conductive terminals through a stamping process, and the side surfaces of the flanging structures are welding regions welded with the assembly bus bars; and the assembly bus bars penetrate through the bus bar through holes and then are connected with the bus bar welding region through electric resistance welding. The invention further provides a split type photovoltaic module junction box applying the bypass element module. According to the photovoltaic module bypass element module, the bus bar through hole and welding structure is formed at the same time through one stamping process, bus bars and a conductive terminal can be welded and fixed directly through an electric resistance welding process, the structure process is simplified, the process efficiency is higher, environmental protection is better achieved, and the bypass element module is suitable for automatic and efficient production of photovoltaic module junction boxes.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic power generation, in particular to a photovoltaic module bypass element module suitable for the application of high-power photovoltaic modules and a split photovoltaic module junction box with the bypass element module. Background technique [0002] Solar photovoltaic modules are devices that convert solar energy into electrical energy. In the production process of photovoltaic modules, the junction box plays an important role in the effective output of photovoltaic power. Its main function is to output the current generated by photovoltaic modules and protect solar photovoltaic modules. The current generated by each solar panel is relatively small, and it is necessary to use a photovoltaic junction box to electrically connect multiple solar panels to each other, so that the current generated by multiple solar panels can be aggregated and output to form a photovoltaic system with a certa...

Problems solved by technology

[0005] However, there are still some problems in the application of this new type of bypass element module, such as the need to punch separately to form the busbar perforation and the welding area for storing solder; it is necessary to store solder in advance in the welding area; Soldering is done manually, the efficiency is relatively low, and soldering will also produce tin fumes harmful to the human body; therefore, further improvement is needed for this modular bypass element
