Problems solved by technology
The length of the cables on the junction box will be longer than the actual length, resulting in waste of materials and increased costs; and after the junction box with cables is installed, it is difficult for the corresponding photovoltaic modules to be automatically transferred
The industry also discloses connectors for photovoltaic junction boxes, but their assembly and connection methods are fixed. With the development of photovoltaic module technology, the installation methods of modules are also more flexible. In addition to extending the cables of the junction box along the long sides of the modules, It may also be perpendicular to the long side of the corresponding photovoltaic module or other angles, which makes the cable have long-term stress and is easy to age

The present application provides a photovoltaic junction box and a photovoltaic module. The photovoltaic junction box includes a box body, a conductive sheet arranged in the box body, a first connector connected to the conductive sheet, and a A second connector that is rotatably plugged in and used for connecting cables; the second connector rotates relative to the first connector so that the cables can be connected to the box in different directions. The photovoltaic module using the photovoltaic junction box above can flexibly adjust the connection direction of the cable and the box body according to the on-site installation requirements, reduce the internal stress of the cable, and ensure the safety of the connection.
Description
technical field [0001] The present application relates to the technical field of solar power generation, in particular to a photovoltaic junction box and a photovoltaic module. Background technique [0002] The junction box is an important part of the photovoltaic module, and usually includes a box body, conductive terminals and diodes arranged in the box body, and the conductive terminals are connected to the bus bars drawn from the battery series; the diodes are arranged in parallel with the battery series to Form abnormal protection for photovoltaic modules. [0003] The junction box is also connected with cables to realize the electrical connection and power output of the photovoltaic module. The cables are usually installed by the junction box manufacturer, fixedly connected to the box body in a predetermined direction and communicated with corresponding conductive terminals. The length of the cables on the junction box will be longer than the actual length, resulting...
