Description

[Detailed description of the invention] <Technical field of the invention> This invention relates to a cable duct device for leading cables into an electrical control panel.

<Prior art> Figures 1 and 2 show conventional examples of this type of cable duct device, in which 1 is a cable, 2 is a door, 3 is a bottom opening 4, and an opening 5 on the door 2 side. a cable support 6 along the opening 5;
This is a duct having a support plate 7 for fixing it. still,
This cable support 6 is fixed to a support plate 7 with fixing screws 8. 9 is a shielding plate that divides the cable duct chamber 22 to form another chamber 24;
3 has an opening 10 in the bottom wall through which the cable 1 is led, and the surface facing the opening 5 is cut out to form an opening 23. This shielding plate 9 is fixed with a fixing screw 8.
It is fixed to the cable support 6 by. Reference numeral 11 denotes a top plate, which is fixed to the duct 3 with fixing screws 12.

The conventional cable duct device is constructed as described above, and the cable support 6 is formed from a member having a rectangular cross section in order to securely attach the shielding plate 9 to the upper surface thereof. Therefore, when pulling the cable 1 into the electric control board 13, there was a risk that the cable 1 would be damaged by the corner of the cable support 6.
In addition, since the shielding plate 9 has few bends 9A to form the opening 23 on the door 2 side, when the number of cables 1 stored in the chamber 24 increases, there is a risk that the cables 11 may protrude from the opening 5 of the duct 3. .

<Summary of the invention> This invention aims to improve the above-mentioned drawbacks of the cable duct device, and by improving the cable support, the cable can be easily removed from the opening of the duct without damaging the cable. It is designed so that it does not protrude.

<Embodiment of the invention> An embodiment of the invention will be described below with reference to FIGS. 3 to 7. In these figures, the same elements as in FIGS. 1 and 2 are given the same reference numerals to simplify the explanation.

In the figure, reference numeral 14 denotes a cable support metal, which is formed of a member having a circular cross section. 16 is a shielding plate 18
This is a fixed metal that is fixedly attached to the end of the cable support metal 14 on the installation side and is used to place and support the shielding plate 18 in a fixed manner. This fixing metal 16 has a flat plate portion 16 at one end.
a, an L-shaped plate portion 16b at the other end, and a flat plate portion 16c rising from the flat plate portion 16a and extending horizontally at the intermediate portion to continue to the L-shaped plate portion 16b. Then, the fixing plate 16 is fixed by inserting the cable support plate 14 through the through hole 17 provided in the L-shaped plate part 16b, and fixing the flat plate part 16a together with the cable support plate 14 end with the fixing screw 8 at the support plate 7 end. It can be attached by attaching it and tightening it together. The shielding plate 18 is placed on the upper surface of the flat plate portion 16c of the fixing metal 16, and is fixedly supported by the fixing metal 16 with fixing screws 20.

Cable supporting members 19 are arranged at intervals along the surface of the opening 23 of the cable duct chamber 24, and are made of a tubular body, and are fixed to the bottom wall of the shielding plate 18 with fixing screws 20, and are erected.

The end of the shielding plate 18 on the side of the opening 23 is bent downward so as to come into contact with the upper surface of the support plate 7.

According to this configuration, since the cable support 14 is made of a member having a circular cross section, when the cable 1 is drawn into the electric control panel 13, a downward pulling force or an opposite force is applied to the cable support 14. The cable 1 can easily be pulled into the electric control panel 13, and there is no risk of damaging the cable 1. In addition, since the cable support member 19 is fixed and erected on the shielding plate 18 with the fixing screws 20, even if a large number of cables 1 are stored in the chamber 24,
There is no fear that the cable 1 will protrude from the opening 5.

<Effects of the invention> As explained above, according to the invention, the cable support is formed of a member having a circular cross section, and the fixing metal for fixedly supporting the shielding plate is attached to the cable support. It is possible to prevent damage to the cable, and at the same time, it is possible to easily fix the shielding plate on the support. Furthermore, by erecting the cable support member at the opening of the shielding plate, even if there are a large number of cables stored in the shielding plate, the practical effect of effectively preventing cables from protruding from the opening of the cable duct chamber is great. It is something.
