Abstract

The utility model relates to a branch connection box. The branch connection box comprises a box body and a base, wherein electrical components are accommodated in the box body, and a side wall of the base is provided with convection holes. When the electrical components work, heat will be generated, so the temperature of the air in the box body is quite high. Because the side wall of the base is provided with the convection holes, the air in the box body will flow towards the base, thus, air convection is produced, moisture in the vicinity of the base can be taken away, thereby avoiding the generation of condensation. In addition, the temperature of the air in the box body is quite high, the temperature of the base can be increased, thereby further avoiding the generation of condensation. As a result, an extra heating device is not required to be added in the branch connection box, which enables structural simplicity; and further, the air of which the temperature is quite high in the box body can be taken away, the temperature inside an accommodating cavity can be maintained in a lower-temperature range, and therefore, the generation of condensation can be avoided, and the normal operation of the electrical components can be facilitated at the same time.
