Although there are various forms of this braided wire, there are, for example, those shown in FIGS. 8 and 9. 8 and 9, FIG. 8 is a perspective view showing a schematic configuration of a braided wire with a display, and FIG. 9 is a single state of the braided wire 2 constituting the braided wire with a display (a state before branch connection). FIG. The assembled electric wire shown here is disclosed in Japanese Utility Model Laid-Open No. 57-43571 as a unit cable used for a unit house or the like. On the other hand, display of application information has been required for this assembled wire according to user needs. As shown in FIG. 8, the display-assembled electric wire 1 connects the joint terminals 3 of the plurality of electric wires (cables) 2 for electric wires in a single bottomed tubular connection body 5 to form a branch. A wiring structure that is integrated at one location is being constructed.

The connection body 5 is a so-called connection box made of insulating plastic. Usually, an insulating thermosetting resin is molded in the connection body 5 to fix and protect the branch-connected conductor. Is made. In addition, the strand 2 for the assembled electric wire
Is a coated electric wire having an insulating outer coating 7, and an appropriate cable such as a two-core cable or a three-core cable is used depending on the application.

[0004] In the case of the assembled electric wire 1 with a display, as shown in FIG. Information (in the illustrated example, “01 distribution board” indicating the connection destination is application information) 9 is displayed. More specifically, the display of the application information 9 on each of the wires 2 for the assembled electric wire is performed by processing the end of each of the wires 2 for the assembled electric wire (a terminal opposite to the joint terminal 3 and connected to a load (equipment, etc.)). as starting point side of the terminal) 11 which is, at the same time to regulate the separation dimension L ₁ from the processing terminal 11 to the first display position, the second and subsequent display interval L ₂
Is constant. The above-described braided electric wire 1 with a display is carried in a factory in a state where it is completed in the form shown in FIG. 8.

[0005] Then, as shown in FIG. 10, the assembled electric wire 1 with the display carried into the site is connected to the connection body 5 by the underside of the ceiling 12.

Is connected to a distribution board (circuit breaker) 13 and the other remaining wires 2 are simply connected to corresponding loads (equipment and the like). The complicated branch connection work between can be completed.

[0006] Moreover, as shown in FIG.
For example, since the use information 9 is displayed at a substantially fixed position on the first side, when each processing terminal 11 is connected to the corresponding load, a check for preventing incorrect wiring or the like is easily performed near each load. Also in this respect, the workability of the indoor electric wiring can be improved.

[0007]

By the way, in the above-mentioned wire assembly with display 1, the length of each wire 2 for the wire assembly extending from the connection body 5 is determined by the load corresponding to the installation position of the connection body 5 indoors. Is determined by the positional relationship with the installation position, and the length of each of the strands 2 for the assembled electric wire is a specific length. Therefore, in the conventional display-assembled electric wire 1 in which the application information 9 is displayed on the strand 2 for the electric wire with the processing terminal 11 as a starting point, the joint terminal 3
The distance from the side to the first display of the usage information 9 is different and different for each strand 2. Therefore, when determining the installation direction of each strand 2 while confirming the display of the usage information 9 on the ceiling 12, it is troublesome to search for the display position of the usage information 9 for each strand 2 for the assembled electric wire. was there.

In recent years, CAD has become widespread, and it is possible to adopt a design method in which a computer automatically calculates necessary materials at the time of designing by CAD. And, for example, in the case of the above-mentioned wire assembly 1 with a display, CAD
