Abstract

The application discloses a photovoltaic junction box with a temperature monitoring structure and relates to the technical field of photovoltaic junction boxes. The photovoltaic junction box comprises a shell, the shell is detachably connected with a gland, the gland is provided with a temperature sensing module for monitoring temperature changes in the shell, the shell is slidably connected with symmetrically distributed first moving blocks and symmetrically distributed second moving blocks, the first moving blocks are provided with first conductive sheets, the second moving blocks are provided with second conductive sheets, the shell is rotatably connected with a driving rod, the driving rod is provided with external threads, and the shell is provided with connecting wires. The photovoltaic junction box is fixed to adjacent electrode sheets on a photovoltaic panel through clamping, so that the installation and dismounting process is faster, additional operations are no longer needed, and the electrode sheets on the photovoltaic panel no longer need to be repeatedly bent during the installation and dismounting process, thereby reducing the probability of breakage of the electrode sheets on the photovoltaic panel.
