[Industrial applications]

 The present invention relates to an assembled electric wire joint box used for connecting electric wires in indoor wiring work and the like.

[0002]

[Prior art]

 Recently, in the case of indoor wiring work for each house such as apartments with many identical wiring, in order to perform the work efficiently, a branching connection is created at the factory, brought to the construction site and wired according to the wiring diagram. It is taken.

FIG. 6 is a partially cutaway perspective view showing a structure of a conventional combined electric wire joint box used in such a construction method. A plurality of electric wires 1 to 8 having a two-core or three-core structure is shown in FIG. In the terminal of (1), the core wires of the first phase to the second phase are exposed by cutting off the outer sheath. The figure shows a state in which the first-phase or second-phase core wires 9 and 10 of the electric wires 5 and 8 are exposed. In order to connect the core wires 9 and 10 with the first phase or the second phase, the insulator at the tip is stripped off, and the conductors 11 and 12 are exposed.

Then, with the exposed portions of the conductors 11 and 12 placed inside the ring sleeve 13, the ring sleeve 13 is compressed from the outside by a tool to crimp and connect the conductors 11 and 12 to the ring sleeve 13. The periphery of is covered with an insulating cap 14. The ring sleeve 13 coated in this manner is protected together with other ring sleeves by covering a cap-shaped plastic joint box 15. In this case, the connection diagram number 16 is displayed on the surface of the joint box 15.

Here, the terminals of the electric wires 1 to 8 are connected at the factory according to the wiring diagram as shown in FIG. 5, and are wired at the construction site while looking at the wiring diagram and the floor plan of the house.

[0006]

[Problems to be solved by the device]

 In such a conventional combined wire joint box, only the wiring diagram number 16 is displayed. Therefore, in conducting the actual indoor wiring work, the person in charge remembers the wiring diagram as shown in Fig. 5 and the wiring is performed while considering the floor plan of the house, so I forgot the wiring diagram. In that case, there is a problem in that efficiency is not improved because it requires a troublesome work such as going to the wiring diagram each time.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide an assembled wire joint box capable of efficiently performing indoor wiring work. It is what

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the assembled wire joint box of the present invention covers the connection part of the conductor, and in the cap-shaped assembled wire joint box that protects this connection part, the outer surface is formed of a transparent resin material. A storage section is provided along the inner circumference to store the wiring diagram.

[0009]

[Action]

 According to the above means, since the wiring diagram can be stored in the storage portion provided along the inner peripheral surface of the outer surface formed of the transparent resin material, while checking the wiring diagram stored in this storage portion, Wiring work can proceed. That is, since the joint box and the wiring diagram are integrated, it is not necessary to go to another place to see the wiring diagram. As a result, it is possible to efficiently carry out indoor wiring work. In addition, since the wiring diagram is stored in the storage part, it will not get dirty or damaged, and the precautions for it will not be required, and it will be easier to handle.

[0010]

[Embodiment] An embodiment of the assembled wire joint box according to the present invention will be described below.

FIG. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a vertical cross-sectional view, FIG. 3 is a vertical cross-sectional view showing a state in which a head is removed, and FIG. FIG. 5 is a perspective view, and FIG. 5 is an explanatory diagram showing an example of a wiring diagram.

The combined wire joint box 20 of the present embodiment is entirely formed of a cylindrical resin material, and at least the outer surface thereof is formed of a transparent resin material. A storage portion 21 for storing the wiring diagram 22 of FIG. 5 is formed along the peripheral surface inside the outer surface. The storage portion 21 is formed by covering the upper portion with the lid 23 so that the stored wiring diagram 22 does not pop out.

The lid 23 is adapted to be coupled to the upper part of the joint box 20 by the screw portion 24. When the wiring diagram 22 is stored, the lid 23 is removed as shown in FIG. In this state, as shown in FIG. 4, the wiring diagram 22 is put in the storage portion 21, and finally the lid 23 is joined.

A handle 25 for fixing the joint box 20 to a structure such as a ceiling is provided on the top of the lid 23.

In the assembled electric wire joint box 20 configured as above, the electric wire 27 is housed in the cylindrical inner space portion 26, and the electric wire 27 is protected.

As shown in FIG. 1, the wiring diagram 22 is stored in the storage portion 21 inside the outer surface so that the wiring diagram 22 can be seen from the outside through the outer surface portion of the transparent resin material. Therefore, it is possible to proceed with the wiring work while watching the wiring diagram 22. That is, since the joint box 20 and the wiring diagram 22 are integrated, the operation of going to another location to see the wiring diagram becomes unnecessary. This allows the indoor wiring work to proceed efficiently. Further, since the wiring diagram 22 is stored in the storage portion 21, it does not become dirty or damaged, and care is not required for that, and handling becomes easy.

[0017]

[Effect of device]

 As is clear from the above description, according to the present invention, the outer surface is formed of the transparent resin material, and the storage portion for storing the wiring diagram is provided along the inner peripheral surface thereof. It is possible to proceed with the wiring work while looking at the wiring diagram from the outside through the outer surface of the material. This eliminates the need to go to another location to see the wiring diagram, and allows the interior wiring work to proceed efficiently. In addition, since the wiring diagram is stored in the storage part, it will not get dirty or damaged, and the precautions for it will not be required, and it will be easier to handle.
