[0002] In the photovoltaic industry, the construction cost is high, so once an accident occurs, the losses caused are relatively large. The connection of photovoltaic cables is also a critical part. If the terminal is burned, it is easy to cause the spread of the fault. If a similar fault occurs in a photovoltaic power station, it is easy to cause an explosion, and the losses caused are incalculable. In addition, for large-scale photovoltaic applications, the photovoltaic cables used will be many and long, and there are many connections. In order to improve the safety of the connection, a junction box is generally used for protection.
