The present application relates to the technical field of photovoltaic junction box, especially to a photovoltaic junction box for offshore photovoltaic module, which comprises a junction casing, a cover plate and a circuit board, the junction casing is internally provided with a crimping assembly for quick disassembly and assembly; the crimping assembly comprises an inner support casing, two conductive sheets, two extrusion pieces and two unlocking blocks, the inner support casing is in abutment with the circuit board, the two conductive sheets are fixedly connected with the circuit board, and the inner support casing is provided with four sliding grooves. By pressing the unlocking block, the hard connection between the lead-out wire and the conductive sheet can be released by one key, without cleaning the silicone at the welding point and melting the solder, the junction casing can be directly scraped off, and during the disassembly process, the problem of lead-out wire breakage or back plate damage due to incomplete melting of solder can be avoided, the fine operation steps are reduced, the replacement operation efficiency is improved, the replacement operation time is shortened, and the safety risk is reduced.
