BEST MODE FOR CARRYING OUT THE INVENTION

<First Embodiment> Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a plan view showing an office to which the wiring structure according to the present embodiment is applied.
The area of 0 square meters is virtually divided into five areas of 20 square meters represented by AE. In the four areas A to D, seven work desks, each indicated by a numeral 11 to 17 indicated by a subscript with an area symbol as a subscript, are grouped and arranged. An information device terminal (not shown) such as a telephone or a computer is arranged at each of the work desks 11 to 17.

Branches 20A to 20D are installed in the four areas A to D, respectively, and one terminal board 21 is installed at a predetermined position on the floor. 24. The wire harness 24 includes a group of electric wires 22A to 22D formed by assembling and twisting twisted pair electric wires.
Which are also twisted together. The wire harness 24 is accommodated in a wiring space under the floor secured by the double floor structure, and is arranged so as to pass through a common path as much as possible, as shown in FIG. In addition, as shown in FIG.
In 3, the wire groups 22A to 22D are twisted with each other to form a single wire.

Although not shown, for example, each of the branching devices 20 is provided with eight modular jacks, and a modular plug (not shown) from the information equipment terminal is detachably connected to each modular jack. Thus, each information device terminal is connected to the terminal board 21. The construction procedure of the wiring structure having the above configuration is as follows. First, in accordance with the layout plan of the work desks 11A to 17D, the positions of the branching devices 20A to 20D to be installed for each group of work desks are determined, and a twisted pair electric wire having a necessary length is determined according to the position and the position of the terminal board 21. Prepare In this embodiment,
Twisted pair electric wires (for example, 4 to 8 cores) having four different lengths corresponding to the regions A to D are connected to the respective branching devices 20A to 20D.
8 are provided corresponding to the number of modular jacks (total 32).

Then, eight twisted pair electric wires having the same length are twisted to be assembled into a single wire to produce electric wire groups 22A to 22D having four different lengths. further,
As shown in FIG. 2, each of the wire groups 22A to 22D is twisted and assembled at a straight line portion to form a single wire harness 24. The ends of each twisted pair electric wire constituting the wire harness 24 may be connected to the branching devices 20A to 20D in advance, or may be connected to the branching devices 20A to 20D in consideration of the required connection. A connector may be provided. A large number of twisted pair electric wires made into a wire harness as described above are carried from a factory to a construction site, where they are laid at predetermined positions in a wiring space under the floor. The ends are connected to the terminal board 21 and the branching devices 20A to 2A.
OD, the wiring work under the floor is completed at once. Thereafter, the modular plug of the information equipment terminal may be connected to the modular jack of each of the branching devices 20A to 20D. In this embodiment, each branching device 20A
In ~ 20D, eight modular jacks are provided and seven information equipment terminals are provided, so one modular jack remains as a spare.

According to the above-described embodiment, the following effects can be obtained. First, as a wiring work, an assembly of twisted pair wires configured as a wire harness 24 is laid in a predetermined wiring space, and each wire is connected to a branching device 20A to 2B.
0D and the terminal board 21. Moreover, since the wire harness 24 is integrated by twisting, it is easy to handle. Further, since the wire harness 24 is highly integrated, the wire harness 24 is compact, and the space for housing the electric wire group can be reduced. Therefore, unlike the conventional wiring structure in which a large number of twisted pair wires are directly connected individually between the terminal board and each information device terminal, a large number of wires do not become disorderly and intricate, and the wires are not disturbed. Since the wiring is arranged neatly as the harness 24, not only the wiring work becomes extremely easy but also the work can be efficiently completed in a short time. In addition, a line having a sufficient capacity can be accommodated even in a narrow wiring space, and the space efficiency is improved.

Further, since the office is divided into a plurality of areas and the branching units 20A to 20D are provided for each of the areas, it is extremely easy to add or move the branching units.
Moreover, when repairing a part of the wiring, first, it is sufficient to specify the group to which the wiring belongs, and then specify the target electric wire within the group, so that the wiring can be easily found. Maintenance and inspection work is also easy. <Second Embodiment> In this embodiment, as shown in FIG.
The above-mentioned electric wire groups 22A to 22D The electric wire groups 22A to 22D are arranged side by side on the same plane at straight lines, and are arranged at regular intervals, for example, in a block 30 as shown in FIG. The block 30 has three grooves 3 formed in a rectangular resin member.
1 are provided, and the wire groups 22A to 22A
D (two in the middle groove, one in each groove on both sides) is inserted from above.

The rest of the structure is the same as that of the first embodiment, and the same portions are denoted by the same reference numerals, and redundant description will be omitted. In the wiring structure having the above-described configuration, similar to the first embodiment, in addition to being able to improve handleability and compactness by integration, each wire group extends in the accommodation space in parallel, so that any wire group 22A
Which turnout device 20A to 20D or terminal board 21
It is easy to grasp whether or not the connection terminal is connected. When it is desired to change the positions of the branching devices 20A to 20D, it is only necessary to shift the block 30 to change the branching portions of the electric wire groups 22A to 22D from the straight line portion.

In this embodiment, the electric wire groups are arranged side by side and stopped by the block 30. However, the electric wire groups may be simply arranged side by side without being stopped by a block or the like. However, if the electric wires are grouped together in a block or the like, the wires can be kept in an orderly state without being separated in the accommodation space, so that the above-described effects of the present embodiment can be exhibited more. <Third Embodiment> In this embodiment, as shown in FIG.
The outer circumference of each of the wire groups 22A to 22D in the first embodiment is wrapped with a polyester tape 25 to improve the unity of the twisted pair wires,
5 are classified into four different colors (each of which is referred to as "polyester tape 25A to 25D"), and the wire groups 22A to 22D.
They can be distinguished from each other.

The other structure is the same as that of the second embodiment, and the same portions are denoted by the same reference numerals, and the description thereof will not be repeated. According to such a wiring structure, in addition to the effect of the second embodiment, due to the difference in the colors of the polyester tapes 25A to 25D, the electric wire groups 22A to 22A
2D can be distinguished at a glance, and work efficiency is improved. The wire groups 22A to 22D are distinguished from each other by, for example, an identification color band for binding wires at intervals, and a flat clip 33 in a fourth embodiment to be described later, in addition to the polyester tape with the identification color. It may be something. Further, if a color corresponding to the identification color is added to the connection terminals of the branching devices 20A to 20D and the terminal board 21, the electric wire group 22
In addition to distinguishing A to 22D, connection work can be easily performed by matching colors.

<Fourth Embodiment> In a wire harness 24 of this embodiment, eight twisted pair electric wires are grouped together at an appropriate interval by a flat clip 33 shown in FIG. 7 to form electric wire groups 32A to 32D. Groups 32A-32D,
As shown in FIG. 6, they are vertically overlapped. The other structure is the same as that of the second embodiment, and the same portions are denoted by the same reference numerals, and redundant description will be omitted. With this configuration, the sub-harness in a region far from the terminal board may be set downward, and the sub-harness may be sequentially stacked on the sub-harness as it approaches, thereby facilitating the wiring laying operation. <Other Embodiments> The present invention is not limited to the embodiments described above with reference to the drawings. For example, the following embodiments are also included in the technical scope of the present invention. Various changes can be made without departing from the scope of the invention.

(1) In each of the above embodiments, each branching device 20
