In addition, the wire shielding component in the embodiment can be specially arranged for the position where the wire connection port and the connecting wire are required to be arranged when the LED box body is manufactured (for example, one wire shielding component is arranged at the rear side of each LED module), the space occupied by the wire shielding component is small, and accordingly, the space required when the connecting wire is plugged and unplugged or post-maintenance is carried out is relatively small. Therefore, the technical scheme of the embodiment can effectively solve the problems that the operation is complex and a larger operation space is required when the LED box body is subjected to post-maintenance or the connecting wire is required to be plugged and unplugged in the related technology.

Specifically, the connecting shaft 30 may be a separate component, and may be integrally formed with the connection base 10 or the wire shielding cover 20.

As shown in fig. 1 to 3, the first connecting portion 22 is disposed on the wire shielding cover 20, the second connecting portion 12 is disposed on the connecting base 10, and the connecting shaft 30 is disposed through the first connecting portion 22 and the second connecting portion 12. In the present embodiment, the connection shaft 30 is fixedly connected with the second connection portion 12 and rotatably connected with the first connection portion 22, so that the wire shielding cover 20 can rotate with respect to the connection base 10. Of course, in embodiments not shown in the figures, the connecting shaft may also be fixedly connected to the first connecting portion, rotatably connected to the second connecting portion, or rotatably connected to both the first connecting portion and the second connecting portion.

As shown in fig. 1 to 3, one end of the connecting shaft 30 is provided with a stopper edge 31, the other end of the connecting shaft 30 is provided with an external screw structure 32, and the second connecting portion 12 is provided with an internal screw structure capable of being engaged with the external screw structure 32.

As shown in fig. 1 to 3 and 6, the holder 40 is provided corresponding to the middle portions of the first and

second connection portions

22 and 12. This allows the force applied to the wire-shielding cover 20 by the holder 40 to be also located at the middle position of the wire-shielding cover 20, avoiding deflection or the like of the wire-shielding cover 20. Specifically, in the present embodiment, the first connecting portion 22 includes two first connecting sleeves disposed at an interval, the second connecting portion 12 includes two second connecting sleeves disposed at an interval, an internal thread structure is provided on one of the second connecting sleeves, so that the two first connecting sleeves are located between the two second connecting sleeves when the assembly of the line shielding assembly is performed, and the connecting shaft 30 sequentially passes through the second connecting sleeve not provided with the internal thread structure, one first connecting sleeve, the retainer 40, the other first connecting sleeve, and the other second connecting sleeve, and is screw-fitted with the second connecting sleeve provided with the internal thread structure.

As shown in fig. 1, 2, and 4 to 6, the width of the top plate 23 gradually decreases in a direction from the second end of the top plate 23 to the first end of the top plate 23; the heights of the second side plate 25 and the third side plate 26 gradually decrease in a direction along the second end of the top plate 23 to the first end of the top plate 23. Since the second end of the top plate 23 needs to be provided with the first connection portion 22 and needs to cover the range of the output interface of the control box (needs to cover the line passing port 51 in fig. 9), and the first end of the top plate only needs to cover the range of the input interface of the LED module, the overall size of the line shielding cover 20 gradually contracts in the direction from the second end of the top plate 23 to the first section of the top plate 23, and the consumable parts of the line shielding cover 20 are reduced on the premise of ensuring the protection effect on the line passing port and the connection line.
