Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention conveniently uses a movable partition panel to supply power to various devices in an office or the like where a large number of complicated electronic devices such as computers are installed. The present invention relates to a power supply device that can be performed.

[Conventional technology]

Office equipment such as computers, copiers, and facsimiles is often installed and used in a workstation that is configured centrally with movable partition panels.In such a case, the partition panel skirting board is usually used. It is used as a wiring duct, and an outlet is attached to this to supply power.

As a power supply device for that purpose, there is, for example, one described in the publications listed below.

Japanese Utility Model Publication No. 49-60298 Japanese Utility Model Publication No. 58-90017 Japanese Utility Model Publication No. 59-85812 Japanese Utility Model Publication No. 59-106918 Japanese Utility Model Publication No. 59-142317 Japanese Patent Application Publication No. 59-201623 Japanese Patent Invention Problems to be Solved by the Invention] It is particularly required for a computer that the supply voltage during programming is stable.

However, in all the conventional power supply devices, since the power supply circuit of the installed device is common, if the starting current is large, for example, if a copying machine, a facsimile, etc. start at the same time,
If the voltage drops temporarily or is severe, the circuit breaker may break and a power failure may occur. In addition, the computer may malfunction due to electrical noise from a fluorescent lamp or the like.

If a separate power supply circuit for the computer is installed, this problem will be solved, but the wiring work will be troublesome, and it will be difficult to change the layout of the partition and the installation location of the computer.

Further, two independent power supply circuits may be provided in the wiring duct, but cords and connectors are remarkably increased, and there is a risk of incorrect connection.

[Means for solving problems]

The present invention penetrates the partition panel in the lateral width direction, and a wiring duct having a window hole in a key portion, and is inserted into the wiring duct, has a length equal to or longer than the length of the wiring duct, and a terminal,
A power supply cable that includes a power receiving connector and a power supply connector and can supply power from a plurality of power sources, an outlet box that is attached to a window hole of the wiring duct and has an appropriate number of outlets, and the outlet can be any of the power supply cables. A power source selection device for switching connection to the power source of the power source, the power source selection device having an intermediate outlet having a feed electrode connected to each power source of the power feeding cable, and a removable outlet capable of being selectively connected to the feed electrode. It is characterized by being exposed from the window hole of the wire duct.

[Work]

In the present invention, since the power supply cable as described above is used, it is possible to easily form a plurality of systems of power supply circuits in the wiring duct at the same time when the partition panels are connected, and the layout can be changed. It's easy.

In addition, a desired power source can be switched by the power source selection device to easily connect to various devices, and the various devices can be easily moved.

Upward and downward engaging projections (9) are provided near both ends of the projections, respectively.

Reference numeral (10) is a cover of the skirting board (2), and a window hole (11) is cut in a portion of the laterally long outer surface plate (10a) facing any of the mounting holes (8). Bending pieces (10b), which are horizontal and are directed inward, are then continuously provided at both upper and lower edges of the outer surface plate (10a).

When the cover (10) is parallel to the main body (7) and forcedly pushed toward the main body (7), the tip of the bending piece (10b) is
The cover (10) is elastically engaged with the protrusion (9) of (7),
It is detachably attached to (7).

Both ends of the skirting board (2) thus formed are open.

In the skirting board (2), two core wires each having a length equal to or greater than the length of the skirting board (2) are connected to two single-phase power supplies having different circuit breakers (hereinafter, both power supply circuits are A circuits. -A 5-core power supply cable (12) in which one core wire is a common ground circuit (hereinafter referred to as G circuit) is inserted.

A power receiving connector (13) and a power feeding connector (14) are connected to each terminal of the power feeding cable (12), and a power source selecting device (15) whose details will be described later is connected in the middle.

The power source selection device (15) is fitted into the mounting hole (8) of the main body (7) of the skirting board, and is fixed to the main body (7) with the screw (16).
The front surface of the power source selection device (15) is exposed in the window hole (11) so as to be flush with the outer surface of the cover (10).
