Abstract

The invention discloses a photovoltaic junction box which structurally comprises an external connection end, a top shell, a middle core layer and a bottom connection layer, wherein the external connection end is connected with the middle core layer, the middle core layer is located between the top shell and the bottom connection layer, and the top shell, the middle core layer and the bottom connection layer are fixedly connected. The photovoltaic junction box has the beneficial effects that the positions of a soluble coating layer and a conductive plate are controlled, the loss of water on the bottom connection layer is reduced to the maximum extent under the dual effects, and the situation that the whole device circuit is completely damaged due to water inflow is prevented, so that the protection effect on the interior of the device is achieved, and power supply of solar energy is further guaranteed.
