Regarding removable bulkheads with built-in distribution boards (hereinafter referred to as ``distribution boards'') that can be equipped with communication equipment, we are particularly interested in automation of office work and production (hereinafter referred to as OA and MA
It is called becoming. ) This invention relates to a removable bulkhead with a built-in power distribution board that streamlines power connections and communication line connections for frequently used telephones, facsimile transceivers, word processors, computers, etc.

BACKGROUND ART With the advancement of OA and MA, the use of various electrical devices and information/communication devices is increasing. Since the installation positions of electrical equipment and information/communication equipment are changed as necessary, it is also necessary to move the connection positions of power supplies and communication lines in accordance with the changes. FIGS. 2A and 2B illustrate a conventional movable power source and communication line connection device called a power pole.

In both figures, the upper part of the hollow column 1 is removably fixed to the ceiling 3 by a fixture 2, and the lower end is attached to the floor 4.
shall be maintained as appropriate. A flexible tube 5 is attached to the top of the hollow column 1.
6 is provided, and a communication line 7 and a power line 8 are drawn into the internal space of the hollow column 1 from a duct in the ceiling or the like.
For example, a required number of telephone jack receiving terminal devices 9a and a power outlet 10 are installed at appropriate positions on the side wall of the hollow column 1.
is attached, and inside the hollow column 1, a communication line 7 is connected to a telephone jack receiving terminal device 9a, and a power line 8 is connected to a power outlet 10. When in use, insert the telephone jack 9 into the telephone jack receiving terminal device 9a, and plug the power plug 11 into the outlet 1.

Conventional movable power supplies and connection devices such as power poles have the advantage of conveniently providing a means of connection at any location in an indoor space for both power lines and communication lines, but the reliability of the power supply and computerized The line information system has the disadvantage that it is not always convenient to connect information and communication equipment.

Additionally, in order to ensure safety and avoid electromagnetic influence, communication lines are generally wired a certain distance apart from power lines, and it is difficult to house communication lines and power lines within the same power pole with the above conventional structure. should be avoided as much as possible. Therefore, with conventional power poles, when information and communication equipment will be used in large quantities in the future, a large number of power poles will be installed indoors, and the disadvantage of deteriorating the aesthetic appearance cannot be avoided.

Power supplies for word processors, computers, and the like require high reliability because the results of long-term work can be instantly destroyed by loss of power. In the power poles shown in Figures 2A and 2B, the device power plugs are directly inserted into multiple power outlets, so in the event of a failure such as a short circuit in any of the devices, all devices connected to the same power port will be damaged. There is a high possibility that power will be lost, and there is a relatively large risk of losing the work results. From this point alone, it is considered that the reliability is insufficient.

In order to use telephone lines efficiently, systems in which a plurality of handsets are connected to one telephone line using a key telephone or button telephone system have become widespread.
With conventional power poles and the like, it is difficult to accommodate a branching device for a plurality of handsets connected to the same telephone line, so there is an inconvenience that separate installation space is required for the branching device.
