DETAILED DESCRIPTION OF THE INVENTION A. Object of the Invention (1) Field of Industrial Application The present invention relates to a power supply line for accommodating a power supply line and a signal line in a wiring duct provided on a floor. The present invention relates to a floor wiring storage device that is separated from a signal line communication line for storing a cable.

(2) Conventional Technique In the conventional floor wiring storage device described above, for example, Japanese Patent Laid-Open No.
As disclosed in Japanese Unexamined Patent Publication No. 132710, a power supply line and a signal line are simply defined in a duct body having a U-shaped cross section, that is, in such a duct body. In the past, there was no idea to specially define a dedicated line for connecting each electric wire or signal line in parallel with each through line.

(3) Problems to be Solved by the Invention In the above-mentioned conventional device, when the electric wires (signal lines) are connected to each other in the through lines, the connecting portions are connected to other power lines (signal lines) in the through lines. ) Is more likely to come into contact, and the possibility of problems such as short-circuiting increases accordingly.

In addition, in the above-mentioned conventional device, when trying to deploy a movable outlet, a cable conversion box, or other connecting device to be connected to a power supply line (signal line) in each through line, many power supply lines (signal lines) are corresponded. Not only does the above-mentioned connected equipment interfere with the work when installing the equipment in a transit line, but also the projections and edge parts of these equipment come into contact with the power supply line (signal line), which damages the wire coating and causes a short circuit. There was a risk that problems such as

The present invention has been proposed in view of the above, and enables the respective connections of the power supply line and the signal line to be accurately performed while solving the above-mentioned problems, and there is no difficulty in adding or moving connection devices in the future. It is an object of the present invention to provide a floor line storage device having a simple structure that can deal with this and can contribute to improving the support rigidity of the duct lid.

B. Structure of the Invention (1) Means for Solving the Problems In order to achieve the above object, the present invention relates to a power supply line for accommodating a power supply line in a duct main body having a substantially U-shaped cross section disposed on a floor. A power line passage extending in the longitudinal direction of the duct body and a signal line passage extending in the longitudinal direction of the duct body to accommodate the signal line are defined, and the open upper surface of the duct body is opened and closed by a lid. In the floor wiring storage device described above, in the duct body, a power line connecting line adjacent to the power line passing line via a first partition wall extending in the longitudinal direction of the duct body, and a longitudinal direction of the duct body are also provided.

It can be avoided, and a connecting device such as a cable conversion box to be connected to the signal line can be provided in the signal line connection line and can be separated from the signal line communication line.

Further, particularly in the duct body, the power line connecting line extends in the longitudinal direction of the duct body, and the signal line connecting line extends adjacent to the signal line passing line in the longitudinal direction of the duct body. Since a plurality of holes for exchanging power lines or signal lines are formed at intervals in the longitudinal direction of the duct body, each through line and connection line are formed at desired positions in the longitudinal direction of the duct body.

C. Effects of the Invention As described above, according to the present invention, since the power supply lines can be exclusively connected to each other in the power supply line connecting line different from the power line connecting line, the connecting portion is connected to another power supply. It is possible to avoid problems such as short-circuits that come into contact with the power line, and connect equipment such as a movable outlet that should be connected to the power line in this power line connection line and become independent from the power line communication line. Therefore, even if a large number of power supply lines are installed in the power supply line, it is possible to prevent the power supply line from being short-circuited due to damage of the coating due to contact with the connected device. The facility work of the power line into the power line can be easily performed without being disturbed by the connecting device.

On the other hand, since the signal lines can be exclusively connected to each other in the signal line connection line different from the signal line communication line, the connection portion may come into contact with other signal lines to cause a problem such as a short circuit. It can be avoided, and the connecting equipment such as a cable conversion box that should be connected to the signal line can also be placed in the signal line manufacturing line and can be independent of the signal line line, so Even if there are many signal lines, it is possible to prevent the coating from being damaged by the contact with the above-mentioned connecting equipment and shorting the signal lines.In addition, there is a facility for the signal lines inside the signal line. The work can be easily performed without being disturbed by the connected device.

Further, particularly in the duct body, the power line connecting line extends in the longitudinal direction of the duct body, and the signal line connecting line extends adjacent to the signal line passing line in the longitudinal direction of the duct body. At the desired position in the longitudinal direction of the duct main body, since a plurality of holes for transmitting and receiving power lines or signal lines are formed at intervals in the longitudinal direction of the duct main body, The power supply line or the signal line can be easily transmitted and received, and therefore, it is possible to cope with future expansion or movement of connected devices without difficulty, and the power supply line or the signal line can be lengthened for the transmission and reception. No need to detour. Moreover, the above-mentioned work of exchanging the power supply line or the signal line,
By opening the lid, it is possible to open the upper surface of each of the communication lines and the connection lines in a wide open state, so that the work efficiency can be improved.

Further, since each of the above-mentioned connecting lines can be easily obtained by simply adding the above-mentioned partition wall corresponding to each through-line in the duct body, the structure for adding the connecting lines is very simple and contributes to cost reduction. be able to. Moreover, since the partition wall extending in the longitudinal direction of the duct main body to define each of the connection lines is specially provided, the supporting rigidity for the lid can be enhanced over a wide range in the longitudinal direction of the duct main body, and thus the reinforcing structure of the lid itself is simplified. At the same time, it can contribute to making the lid thinner, lighter and wider.
