BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire joint box used for connecting electric wires in indoor wiring work or the like.

[0002]

2. Description of the Related Art In recent years, in indoor wiring work of each house of an apartment or the like having many identical wirings, in order to perform the work efficiently, a branch connection is created at a factory, and the branch connection is brought to a construction site and the wiring connection is made according to a wiring diagram. The wiring method is adopted.

FIG. 6 is a partially cutaway perspective view showing the structure of a conventional electric wire joint box used in such a construction method, and shows a terminal of a plurality of electric wires 1 to 8 having a two-core or three-core configuration. In the above, the core wire of the first and second phases is exposed by cutting off the outer sheath. The figure shows a state where the first-phase or second-phase core wires 9 and 10 of the electric wires 5 and 8 are exposed. These core wires 9 and 10 are connected to each other in the first phase or the second phase.
The insulator at the tip is stripped, and the conductors 11 and 12 are exposed.

[0004] With the exposed portions of the conductors 11 and 12 placed inside the ring sleeve 13, the ring sleeve 13 is compressed with a tool from the outside of the ring sleeve 13, whereby the conductor 1 is compressed.
1 and 12 are connected by crimping, and the periphery of the ring sleeve 13 is covered with an insulating cap 14. The ring sleeve 13 coated in this way is a plastic joint box 1 in the form of a cap together with other ring sleeves.
5 for protection. In this case, a connection diagram number 16 is displayed on the surface of the joint box 15.

[0005] Here, the terminals of the electric wires 1 to 8 are connected in a factory according to a connection diagram as shown in FIG. 5, and are wired at a construction site while viewing the connection diagram and the floor plan of the house.

[0006]

In such a conventional electric wire joint box, only the connection diagram number 16 is displayed. Therefore, when performing the actual indoor wiring work, the connection diagram as shown in FIG. 5 is memorized by the person in charge, and the wiring is performed while considering the layout of the house. In each case, a troublesome operation such as going to a connection diagram is required each time, and there is a problem that efficiency is not improved.

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

[0008]

In order to achieve the above object, a joint box for electric wires according to the present invention comprises:
Houses multiple conductor connections that connect the ends of the core wires
And a cap-shaped braided wire joint for protecting the connection portion of the wire.
An int box, wherein the electric wire joint box is provided.
Side wall is formed by a double wall of an inner side wall and an outer side wall,
The wall is formed of a transparent resin material, and the outer wall and the inner wall are formed.
A storage section is provided between the wall and the storage space for storing a connection diagram.

[0009]

According to the above means, the transparent resin material is used.
Groove between the outer and inner walls along the inner peripheral surface of the outer wall
Since can be stowed a connection diagram in the storage unit be constituted by a space is provided Jo, outside the wiring diagram which is accommodated in the housing part
The wiring work can be advanced while seeing from the section . That is, the wiring work of the assembled wire joint box is performed because the assembled wire joint box and the connection diagram are integrated.
It is not necessary to go to a place other than the place to see the connection diagram. Thereby, indoor wiring work can be efficiently advanced. Further, connection diagram is combination wire joint box
Since it is stored in the storage section of the box, it does not become dirty or damaged, and attention for soiling / breakage is unnecessary,
Handling becomes easy.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the assembled wire joint box according to the present invention will be described.

FIG. 1 is a perspective view showing an embodiment of the present invention.
2 is a longitudinal sectional view, FIG. 3 is a longitudinal sectional view showing a state in which a head is removed, FIG. 4 is a perspective view showing a state in which a connection diagram is stored, and FIG. 5 is an explanatory diagram showing an example of a connection diagram.

[0012] The electric wire joint box 20 of the present embodiment.
Is formed entirely of a cylindrical resin material . This group
The side wall of the electric wire joint box 20 is connected to the inner side wall 28 and the outer side.
The inner side wall 28 and the inner side wall 28
A groove having a predetermined interval with the outer side wall 29 and a bag
A storage part 21 for storing the connection diagram 22 of FIG. 5 is formed along the peripheral surface of the inner wall 28 . Also,
Inside the cylinder housing the connection part of the electric wire 27 by the side wall 28
A space 26 is formed, and the electric wire joint box is formed.
At least one of the side walls of the housing 20 and the outer wall 29 are transparent.
It is made of bright resin material. And this storage section 21
Is formed so that the lid 23 is put on the upper part and the connection diagram 22 stored in the storage part 21 does not jump out.

The lid 23 is connected to the upper part of the joint box 20 by a screw portion 24. When storing the wiring diagram 22, the lid 23 is removed as shown in FIG. In this state, as shown in FIG. 4, the connection diagram 22 is put in the storage section 21, and the lid 23 is finally connected.

At the top of the lid 23, a joint box 2
There is provided a handle 25 for fixing O to a structure such as a ceiling.

The assembled electric wire joint box 20 accommodates the electric wire 27 in the cylindrical inner space 26 defined by the inner wall 28 and protects the electric wire 27.

Then, between the inner wall 28 and the outer wall 29
As shown in FIG. 1, a connection diagram 22 is accommodated along the outer surface of the inner wall 28 in the formed storage portion 21, and is connected from the outside via an outer wall 29 made of a transparent resin material.
2 is visible, so it is stored in the storage
Wire joint box 2 while viewing the connection diagram 22
0 wiring work can be performed. That is, since the jointed wire joint box 20 and the connection diagram 22 are integrated, the jointed wire joint box 20 is
It is not necessary to go to a place other than the place where the wiring work is performed to see the wiring diagram. Thereby, indoor wiring work can be efficiently advanced. Also, the electric wire join
Connection diagram 22 of the connection box 20
Since it is stored in the storage portion 21 of the box 20, it does not become dirty or damaged, and there is no need to pay attention to soiling or damage , and handling can be facilitated.

[0017]

[Effects of the Invention] As is clear from the above description, according to the present invention , the side wall of the assembled wire joint box is connected to the inner wall.
The outer wall is formed of a double wall, and the outer wall is made of a transparent resin material.
And a groove-shaped space between the outer wall and the inner wall.
Because there is a storage unit that is configured between and stores the connection diagram,
The wiring operation can be performed while viewing the wiring diagram from the outside through the outer wall of the transparent resin material. As a result, the set power
This eliminates the need to go to a place other than the place where the wiring work of the line joint box is performed and to see the wiring diagram, and thus the indoor wiring work can be efficiently advanced. In addition,
The connection diagram of the joint box is
Since it is stored in the storage part of the box, it does not become dirty or damaged, and there is no need to pay attention to soiling or damage, which makes it easier to handle .
