It also includes a cable fixing clamp 5. The cable fixing clamp 5 includes a clamp base part 6 and a clamp splint part 7. The clamp base part 6 includes a clamp base 61. The clamp base 61 is in the shape of a long strip. On one side of the long strip, there is a first long notch 611. At both ends of the clamp base 61, there are hook parts 62. The hook parts 62 are in a U-shaped structure. The hook parts 62 include a first hook part 621 that holds the clamp base, and also include a hook extension part 622. The clamp splint part 7 includes a clamp splint 71. The clamp splint 71 is in the shape of a long strip. On one side of the long strip, there is a second long notch 711. At both ends of the bottom of the clamp splint 71, there are limit blocks 73. The limit blocks 73 define a positioning space for the hook extension part 622. The clamp splint part 7 is placed on the hook extension part 622, and the hook extension part 622 is stuck in the positioning space defined by the limit blocks 73. The first long notch 611 and the second long notch 711 form a cable accommodation cavity 8.

[0025] The structure of this embodiment is reasonable. By placing power cables, control cables, and optical cables and pigtails that need to leave pigtails in layers in sequence, the classification is reasonably arranged, reducing inductive interference and making the classified placement more orderly. When leading out cables to the screen cabinet, by using the cable fixing clamp 5 to fix the cables in the same classification and on the same organizing layer during the process arrangement, the cables are arranged neatly and orderly during the longitudinal emergence process, and the cumbersome and troublesome fixing process of fixing each cable with a wire clip in the traditional technology is eliminated. The cable fixing clamp 5 of this application adopts a special structure. First, a column of similar cables is grouped and arranged by the clamp base 61, and then the clamp splint 71 is placed on the hook extension part 622, thus completing the grouping and fixing of a group of cables. The operation is simple and fast, and the cable fixing clamp 5 can be adjusted in multiple dimensions according to the installation space, which is practical, convenient, and has good effects.
