In addition, the first coupling part 140 is moved through the first hole 111a, the third hole 121a, the first guide hole 130a, and the third guide hole 180a, so that the first hole 111a is moved. 1 coupling part 140 is prevented from interfering with the movement of the first plate 120 .

And, when the first coupling part 140 rotates clockwise, the first plate 120 is fixed to the upper part 111 by the first coupling part 140 .

7 is a plan view illustrating a cable duct for a distribution box according to another embodiment of the present invention.

Referring to FIG. 7 , a cable duct 200 for a distribution box according to another embodiment of the present invention may include a fifth guide part 230 and a fifth coupling part 240 together with the components of the above-described embodiment, , Description of components identical or similar to those of the above-described embodiment will be replaced with the above-described description, and the description will focus on the fifth guide portion 230 and the fifth coupling portion 240.

The fifth guide part 230 has the same structure as the first guide part 130 described above. Also, the fifth guide part 230 is spaced apart from the first guide part 130 and coupled to the upper part 111 .

The fifth coupling part 240 moves along the fifth guide part 230 and couples the first plate 120 and the upper part 111 . In this way, according to another embodiment of the present invention, the fifth coupling part 240 stably couples the first plate 120 and the upper part 111 together with the first coupling part 140. .

In addition, although not shown in the drawings, the cable duct 200 for a distribution box according to another embodiment of the present invention includes a sixth guide part similar to the above-described second guide part 160 and the above-described second coupling part 170 and A similar fourth coupling portion may be further included. As described above, in the cable duct 200 for a distribution box according to another embodiment of the present invention, the first coupling part and the second coupling portion are provided as a pair, and the second coupling portion and the fourth coupling portion are provided as a pair. Thus, the first plate 120 and the upper portion 111 are stably coupled, while the second plate and the lower portion are stably coupled.

Although the embodiments of the present invention have been described, the spirit of the present invention is not limited by the embodiments presented herein, and those skilled in the art who understand the spirit of the present invention may add or change components within the scope of the same spirit. Other embodiments can be easily proposed by adding, deleting, adding, etc., but this will also be said to be within the scope of the present invention.
