Directional cable box in railway signal box

Abstract

The invention provides a directional cable box in a railway signal box. The directional cable box comprises a box body and a top cover. The box body is a symmetrical structure with an A-A axis as a center, the box body is internally provided with a terminal fixing plate which is provided with a first terminal, a plurality of terminals, a last terminal, a grounding copper bar, and a surrounding grounding slot. The surrounding grounding slot is embedded in the middle of the plate, the plurality of terminals are distributed in a ring structure between the first terminal and the last terminal, arc-shaped support members with grooves in the middle and T-shaped support members are alternately arranged among the first terminal, the plurality of terminals and the last terminal in order, two ends of each of a support member abut against two adjacent terminals, a support member is not between the first terminal and the last terminal, an arc-shaped support member is disposed between two terminalsadjacent to the A-A symmetric axis, the grounding copper bar is set between the first terminal and the last terminal, the top cover is provided with a waterproof cap, and a ring-shaped edge of an inner side of the top cover is provided with bosses in a ring. According to the cable box, a grounding wire and other lines are separated, therefore, the grounding wire is arranged regularly, and the grounding wire can be quickly distinguished and replaced when a line is damaged.

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...
