JUNCTION BOX, PHOTOVOLTAIC MODULE AND WIRING METHOD

WIPO Patent Application WO/2021/208456

A1

A junction box (220), a photovoltaic module (200) and a wiring method, relating to the technical field of photovoltaics, and aiming to improve the wiring reliability and stability of the junction box (220) so as to ensure the generating capacity and safety of a photovoltaic system. The junction box (220) is used for the photovoltaic module (200) having an outgoing line (L), and comprises: a box body (221) and a terminal board (222) arranged in the box body (221). The box body (221) is provided with a first through hole (2210) used for limiting the outgoing line (L). The terminal board (222) is located on one side of the first through hole (2210), and has a welding region (222Ar) and a ridge structure (223). The ridge structure (223) defines that the flow region of a solder is at the welding region (222Ar). When the junction box (220) is electrically connected to the outgoing line (L), the outgoing line (L) passes through the first through hole (2210) and is welded on the welding region (222Ar). The photovoltaic module (200) comprises the junction box (220), and the junction box (220) is used for photovoltaic power generation.
