Description

technical field

[0001] The patent of the invention relates to the field of cable boxes, in particular to a directional cable box in a railway signal box. Background technique

[0002] With the progress of society and the improvement of economic level, the level of informatization has also been greatly improved, resulting in the laying of a large number of cables on the railway to transmit signals. The cables used include various power cables, busbars, Grounding wires and other lines, the use of these lines will use the cable box, the cable box can control the cable line very well, and have a good control effect, but the existing cable box cannot connect the grounding wire and the busbar, etc. The other lines are separated. The grounding line comes in from several cable ducts and then goes out from other incoming lines. It is unsafe and the cables are easy to be connected incorrectly. Contents of the invention

[0003] In order to solve the above problems, the present inve...
