A cable branch box with an optimized heat dissipation structure

Abstract

The utility model relates to the field of cable branch box, concretely is a kind of cable branch box of optimization heat dissipation structure, including branch box body, branch box body one side is equipped with mounting hole, branch box body top is equipped with several heat dissipation holes. Compared with prior art, when the positioning block is aligned with the positioning groove, due to the force of tension spring, it is convenient to drive the positioning block to be embedded in the inside of positioning groove, so that the outer wall of positioning rod is connected with connecting ring, while the clamping block of one end of positioning rod is embedded into clamping groove, positioning rod is connected with positive and negative rotation fan shaft center at this time, when positive and negative rotation fan sends air to branch box body outside, drive two groups of brush plate to clean before and after dust screen respectively, dust after dust screen falls out of branch box body inside under the flow of air, dust before dust screen directly falls out of dust screen, so that dust screen is cleaned sufficiently, avoid the dust adhered in dust screen to form accumulation, affect normal heat dissipation.
