By mounting them in parallel, it is possible to facilitate selective conduction through the connecting parts.

On the other hand, on the floor 2, the load power supply areas serviced by the distribution board 1 are divided into a plurality of divided areas D1 to D4, and each of the floor-embedded relay boxes 7I to

The circuit connection terminals are connected regardless of the continuity state of the connecting parts between each circuit connection terminal, and these can be routed through under the panel of the office floor, for example, without being exposed on the floor.

It becomes possible to perform circuit relay from a single-phase circuit (the remaining circuit is kept as a backup) to a single-phase two-circuit circuit.

Therefore, if it is necessary to rearrange the layout in response to the addition or relocation of loads, this will be done by selectively connecting the circuit connection terminals of the primary side terminal group 4 and the secondary side terminal group 5, and the secondary m@ Circuit connection terminals and each relay box 7□ in Miko group

It is assumed that no processing such as transfer is performed for 9.

As shown in FIG. 2, electrical equipment 10 that is arbitrarily installed in the load supply @fiJf area that is serviced by the distribution panel 1 is connected to a relay box that provides the optimum wiring conditions for its installation. , guide the wiring material 11 attached to the electrical equipment or used as a relay for it, and connect the plug lla of the wiring material 11 to the relay box 7X.
Outlet 81 or 8. By inserting and connecting the power supply, you can prepare the power supply.

Then, regarding the selected relay box 7, depending on the arrangement of the equipment to which power is to be distributed from the selected relay box 7, select the box? , multiple circuit relay outlets L installed in
A plurality of circuit relay terminals in a secondary side terminal group that are in a conductive relationship with respect to 8x by pre-wiring of wiring materials,
The plurality of circuit relay terminals selected in the secondary side terminal group are electrically connected by the connecting component 6, thereby providing power supply service.

Therefore, if the electrical equipment 10 is relocated or expanded, the connecting parts 6 between the primary side terminal group 4 and the secondary side terminal group 5 in the distribution board 1 will be changed according to the arrangement situation.
In addition to conducting conduction (non-conduction) through switching operations, wiring to the selected relay box is performed under optimal wiring conditions by relocating or adding wiring material 11 that is drawn out from the relay box and reaches the equipment. This can be handled by

Various wiring patterns can be used for the wiring material 11 from the relay box to the electrical equipment.

Figure 3 shows a relay wiring material in which one end of a cord 12 is provided with a plug 13 for insertion into an outlet provided in a relay box, and the other end is provided with an outlet 14 into which the plug of a cord with a plug attached to the equipment is inserted. This is used, for example, to route wiring under desks placed on the floor or through partitions.

FIG. 4 shows an example in which such a relay wiring material or a plug-equipped cord of a device is passed through a seam of a panel 15 on a raised floor and connected to a relay box. With this method, when relocating or adding equipment, it is only necessary to dismantle and reconstruct at least two panels where cords and cords are inserted, instead of dismantling and reconstructing many panels like in the past. The amount of work required is considerably less compared to that of the conventional method.

Figure 5 shows the outlet box 16 on the OA floor.
When using the outlet box 16, the cord 18 with plugs connected to the plurality of outlets 17 and 17 built into the outlet box 16 is guided through the OA floor to the relay box, and the plug 18a of the cord is connected to the outlet of the relay box. It is assumed that the cable is inserted and predetermined wiring processing is performed.

In this case, equipment can be relocated by disassembling several OA floor panels and relocating the outlet box 16.

Further, it is possible to cope with the expansion of equipment by incorporating a plurality of electrical outlets 1-17, 17 into the electrical outlet box 16, and connecting each cord with a plug 18, 18 to a relay box.

In this system, the primary side terminal group 4 on the distribution board 1 is another operation point for relocating or expanding equipment.
The method of switching conduction using the connecting part 6 between the terminal group 5 and the secondary side terminal group 5 can be roughly divided into a cord relay conduction method, and a relay device with a switching function such as relay switching by manual operation or relay automatic switching by a sequencer or microcomputer.

9s, 9s, and 9t each supply one circuit, and the remaining one circuit is left open as a reserve.

Such a conduction mode can be most utilized in accordance with the initial layout plan of the OA equipment. Additionally, one spare circuit can be used for future relocation or expansion of equipment.

Figure 7 shows one of the primary circuit connection terminals 4. in one branch system ①. and one of the circuit connection terminals in another branch system ■4. and the two secondary side circuit connection terminals 5.-9 connected to the relay box 71 by pre-wiring. ．． 5. This shows the case where conduction is established by the cords 6+ and 6t, and two different circuits are introduced into the relay box 7. Therefore, the power supply capacity can be doubled in the area where the relay box is placed.For example, if the current capacity of each branch system is 20A as a commercial power source, the relay box 7, the relay box 4
It can be set to 0A and can supply 4kvA of power.

Such a conduction mode can be used when the load is concentrated in a certain area. Furthermore, by performing the same procedure for all relay boxes, it is possible to cope with a significant increase in the number of devices in the future.

Furthermore, each branch system! , (2) are introduced into one area, so it can be used when there are many different models.

Figure 8 shows the connection between two primary side circuit connection terminals 4+ and 4atm assigned to one branch system ■ by pre-wiring in relay boxes 7I and 7□ located at different positions. Secondary side circuit connection terminal 51 and 5. , conduction is made through cords 6+ and 6z, respectively, and 2 lines are connected from 1 line to 2 lines.
An example of distribution to two relay boxes is shown below.

Such a conduction mode can be used when there are few devices arranged in each region and the load capacity is small.

The above cord leading method can be easily and easily carried out between the primary side terminal group 4 and the secondary side terminal group 5 by using a cord having connectors at both ends that can be inserted into the respective circuit connection terminals to establish continuity. Allows quick selective connections and switching.

By combining or changing the three typical conduction examples described above, it is possible to provide a circuit configuration that can immediately respond to new installation, rearrangement, expansion, or removal of equipment in the load power supply area. be. In this case, it is clear from the above explanation that the pre-wiring as floor wiring from the secondary side terminal group 5 to the relay box does not require any changes in the rearrangement or expansion of the equipment concerned. be.

FIG. 9 shows that between the primary side terminal group 4 and the secondary side terminal group 5,
This is an example in which a relay switching device 19 having multi-contact points is connected and arranged to each of all of the circuit connection terminals, and by switching the relay in the device ff19, any circuit connection terminal of the primary side terminal group 4 is connected. and any circuit connection terminal of the secondary side terminal group can be electrically connected to each other.

Therefore, various types of conduction a can be obtained by the above-mentioned cords only by switching the relays.

For such relay switching, manual operation using push buttons or keyboard operation using a sequencer or microcomputer is appropriate.

Further, regarding the relay switching device 19, it is also possible to introduce an operation history management system and a security management system as additional functions, and according to the additional functions,
It is possible to immediately respond to careless external operations, and it is also possible to prevent careless operations before they occur.

In the above example, two circuits are set for one branch system, and up to two circuits can be taken at the relay box. However, two or more circuit connection terminals are assigned to each branch system to connect two or more circuits. It is also possible to set up multiple circuits.

In addition, in the above embodiment, in the relay box, the outlets for setting a plurality of circuit relay parts are made to correspond to the number of circuit connection terminals selected from the secondary side terminal group. As shown, the other outlet 8 connected by the crossover wiring 20 to the outlet 8I that corresponds one-to-one to the pre-wiring per circuit
! It is also possible to deploy a power supply system, which is used to distribute power to many loads from one pre-wiring connected to one circuit connection terminal.

Furthermore, when selecting a relay box with optimal wiring conditions for equipment that is arbitrarily installed, a relay box that is deployed in the area where the equipment is installed is generally selected, but this is not limited to this. It is also possible to select a relay box that is located in a different, for example, adjacent area to the area to which the user belongs.

〔Effect of the invention〕

As is clear from the above explanation, according to the power wiring system of the present invention, by selective connection using the connection parts between both the primary side terminal group and the secondary side terminal group arranged in the distribution board, from the secondary side terminal group to the Since pre-wiring can connect various circuits up to the circuit connection terminals distributed in the load power supply area, our factory incorporates pre-wiring into a part of the building and relocates it. Enables wiring to be done without the need for additional equipment, and allows easy wiring from relay terminals to equipment when relocating or expanding equipment, and selection between both primary and secondary terminal groups using the relevant connection parts. This can be handled by switching.

Therefore, some simple methods can be used without making any changes to the wiring system, which is wired to a building at the time of construction or expansion, and cannot be relocated or added to without dismantling part of the building. The intended purpose of using this II power wiring system, which makes it possible to flexibly adapt the wiring to the relocation and expansion of electrical equipment, is more than achieved through wiring processing alone.
