Excessive development will also cause problems such as land occupation, excessive consumption of natural resources and environmental pressure. At the same time, the ecological red line problem in the past two years has also made the development of land power stations have many variables, and many power station developers have turned their attention to marine clean energy.

[0003] Offshore photovoltaic projects face complex and harsh service environments. For example, strong winds and waves in the southern waters, typhoons, sea ice in the northern waters, high salt fog, high humidity, and frequent temperature changes all mean that the preliminary work of offshore photovoltaics is more rigorous than that of ground power stations, especially placing higher requirements on junction box connectors.

[0004] At present, most offshore photovoltaic connector solutions are to install an external waterproof sleeve on the outside of the connector. This solution not only requires adding a process to fix the waterproof sleeve on the outside of the connection, which has low production efficiency, but also has high requirements on the material of the waterproof sleeve and high cost. At the same time, during use, we found that its sealing effect is not very ideal.
