It is also the key to whether users are satisfied with the power supply quality. It has the characteristics of easy installation, special technical performance, no site restrictions and wide application. The function of the electrical box is to reasonably distribute electric energy, facilitate the opening and closing operation of the circuit, have a high level of safety protection, and can intuitively display the conduction status of the circuit.

[0003] With respect to the above-mentioned related technologies, the inventors found that the electrical components in the electrical box will generate more heat when used for a long time. The high temperature in the electrical box affects the service life and safety of the electrical components. Traditional electrical boxes mostly use a single heat dissipation component for heat dissipation, and the heat generated by the electrical components far away from the heat dissipation component cannot be dissipated quickly, resulting in uneven heat dissipation and reducing the heat dissipation effect.
