Photovoltaic module junction box and wiring method

Abstract

The invention provides a photovoltaic module junction box and a wiring method, and belongs to the technical field of photovoltaic modules. The photovoltaic module junction box comprises a box body, amounting plate is fixedly connected to the lower inner wall of the box body through screws, four conductive blocks are fixedly connected to the upper end of the mounting plate, left connecting piecesare fixedly connected to the left ends of the four conductive blocks, clamping openings are formed in the upper ends of the four left connecting pieces correspondingly, four first connecting openingsare dug in the lower end of the box body and correspond to the four clamping openings correspondingly, and the right ends of the four conductive blocks are fixedly connected with right connecting pieces correspondingly.The invention aims to solve the problems in the prior art that a buckle is liable to break due to improper disassembly of a junction box, the junction box is difficult to assemble again, the buckle is easy to deform after the junction box is disassembled for many times so as to influence the fastening and sealing effects of the junction box, and the cable outside the junction box is pulled by external force so as to easily cause the fracture of the part at the welding position inside the junction box and influence the use of the junction box.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic components, and in particular relates to a photovoltaic component junction box and a connection method. Background technique [0002] In the prior art, a photovoltaic module (also called a solar panel) is the core part of a solar power generation system and is also the most important part of a solar power generation system, and a single solar cell cannot be directly used as a power source. As a power supply, a number of single cells must be connected in series or in parallel and tightly packaged into components. Its function is to convert solar energy into electrical energy and send it to the battery for storage, or to drive the load to work. [0003] In the existing photovoltaic module system, the connection between photovoltaic modules is generally realized through the junction box and its connecting wires. Since most of the existing junction boxes are fixed by buckles, the inside of the ju...

Problems solved by technology

[0004] The purpose of the present invention is to provide a photovoltaic module junction box and a wiring method, aiming to solve the problem that the junction box in the prior art is easily broken due to improper disassembly, the junction box is difficult to reassemble, and the junction box after repeated disassembly is easy to cause The buckle is deformed, which affects the fastening and sealing effect of the junction box. The cables outside the junction box are pulled by external forces, which may easily cause the components at the welding part inside the junction box to break, thus affecting the use of the junction box.
