Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of junction boxes, in particular to a sealing structure of an offshore junction box. Background Art
[0002] As offshore photovoltaics is a future trend, the use of traditional junction box solutions can no longer meet the harsh weather conditions at sea, and poses great challenges to the sealing and protection of the junction box.
[0003] The existing technical solutions generally use the traditional two-component glue to seal the junction box, and the wire pressing block is still sealed by traditional ultrasound. The disadvantages are: the bonding force between the two components and the box body is not strong. If the cover is just filled with glue like a traditional junction box, water will penetrate into the interior along the gap between the two-component glue and the box body due to long-term harsh environment; in the environment of strong winds, strong waves and heavy rainfall at sea, it is only an ultrasonic process, the wire fixing force is not strong, and there is a great safety hazard.
