Description

Technical Field

[0001] The invention relates to the technical field of cable branch boxes, and in particular to a cable branch box with heat dissipation holes that are wind and rainproof. Background Art

[0002] The cable branch box is only used as a cable branch. The main function of the cable branch box is to branch or transfer the cable. It mainly plays the role of cable branching and cable transfer. At present, the railway distribution network is increasingly using cable power supply. Sometimes there will be a relatively concentrated distribution of independent loads with small capacity. At this time, we usually use cable branch boxes to connect multiple branches of cables. This is because the cable branch box cannot directly operate each line, but only plays the role of cable branching. The main functions of the cable branch box actually include two points, one is to transfer the cable, and the other is to branch the cable. my country's railway coverage is relatively wide. In winter, the cable branch box in the north is prone to ice. Ice will cause erosion on the anti-corrosion layer on the top of the cable branch box. In addition, when it snows, the ice layer will accumulate snow, causing the cable branch box to increase its load and the branch box to be easily crushed. Although the outside of the cable branch box is cold, the internal temperature of the cable branch box is high due to the work done by the current, which will cause internal connection position failures and affect the operation of the train. High temperature will also increase the aging speed of the cable joint position and reduce the service life of the cable joint inside the cable branch box.

[0003] The existing cable branch box is prone to high temperature during use, which affects the service life of the equipment. At the same time, the equipment may be damaged due to heavy snow accumulation, and it is inconvenient to install and fix the cable connector. Therefore, we propose a cable branch box with heat dissipation holes that is wind and rainproof. Summary of the invention
