Abstract

PROBLEM TO BE SOLVED: To perform see-through inspection of internal connection of wires easily by making a see-through window at a position corresponding to the connecting part of a wire bundle and fixing a transparent plate or cover thereto so that the connecting part can be seen through from the outside. SOLUTION: An arrow A represents a wire bundle branched using a connector 13 and a large window is opened from the entire rear surface to the side part of a box body 1. The box body 1 is molded of an easily injection moldable resin excellent in insulation, self-extinguishing properties and economy but difficult to see-through into a structure for containing a branch wire bundle straightly. A window 2 is opened from the entire rear surface to the side part of the box and fixed integrally with a transparent plate or cover. Since a see- through window is made at a position where the connecting part is located and fixed with a transparent plate or cover, the connecting part can be seen through from the outside.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to form a box having a structure capable of storing a connection bundle without bending the connection bundle in a state of being straightly branched and connected. Attach the wire and cable part corresponding to the base of the cable, and tie the appropriate stop holes and hanging bolts to the installation location among the stop holes provided at the top, bottom, left and right, or make it possible to store and install by simple work just to hook and stop,
Although the material of the box body is difficult to see through, it is easy to mold,
It is easy to solve environmental problems, economical, using a self-extinguishing resin material, in order to compensate for the difficulty of seeing through the material, to provide a see-through window at a position where the connection part can be seen through, a transparent plate or A transparent cover is attached so that the internal connection state can be easily inspected from outside.

[0004]

As a means for solving the above-mentioned problems, a resin material generally used is added with self-extinguishing property because it is economical, easy to mold, and has few environmental problems. In the box body, a see-through window was provided at a position corresponding to the connection portion of the connection bundle, and a transparent plate or a transparent cover was attached to the window so that the connection portion could be inspected through the outside.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is a box having a structure capable of storing a branch connection bundle in an electric wiring work straight, and using stop holes provided on the upper right and left sides, and a construction material such as a suspension bolt. Box body that can be tied or hooked to
It is economical, easy to mold, environmental issues, it is molded by adding self-extinguishing properties to an electrically good resin material, and if it makes it difficult to see through, by providing a see-through window in the part where the connection part is located, A transparent plate or a transparent cover is attached to the portion, and the connection portion can be visually inspected from the outside to form a substantially transparent joint box.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings showing an embodiment of the present invention, an arrow A indicates a connection bundle, which is a bundle branched and connected using the connector 13. The arrow B is a see-through window B. A large window is opened from the entire inner surface of the box main body 1 to the side, and a see-through cover 17 is attached to the box so that the connection bundle can be seen through the front part and the side part. The box main body 1 is formed into a structure that can store the branch connection bundle straight, and is made of a resin material which is excellent in insulation, self-extinguishing properties, economical efficiency, is difficult to see through, and is easy to mold. 1-B is a box body B, which is a see-through window B provided from the front to the side of the back of the box. Reference numeral 2 denotes a see-through window, which is provided with a window in the front part on the back of the box body 1 and integrated with a transparent plate 3 so that the connection portion of the stored connection bundle can be inspected through the outside from the outside. Reference numeral 4 denotes a hook, which is provided on the back side of the see-through plate 3, is inserted into the see-through window 2, hooks on the back side edge of the receiving frame 5, and fixes the see-through plate 3. Reference numeral 5 denotes a receiving frame portion, which forms a slight step like a frame, into which the transparent plate 3 is fitted and the transparent plate 3 is fixed. Reference numeral 6 denotes an opening, which is an entrance of the box body. Reference numeral 7 denotes a binding elongate hole, which binds the electric cable 10 corresponding to the base of the connection bundle with a binding band 8 or the like. Reference numeral 11 denotes a bent portion. The plurality of electric cables 10 located immediately behind the binding long hole 7 are bent outward, and even if the wires are lightly bound, the bent portion 11 is blocked by the binding band 8 and stops coming off. Electrical safety is maintained. Reference numeral 8 denotes a binding band, which is an electric cable 10 or a suspension bolt 1.
The binding band is not limited to the binding band 8 as long as it has an insulating property such as a binding wire. Reference numeral 9 denotes a mouth opening portion, which is located in the upper part in the back of the binding long hole 7, and directly binds the electric cable 10, so that the box body 1 can be bound without any trouble even if it is hard or soft. 12 is an electric wire,
A part of a connection bundle in which the electric wire cable 10 is peeled off to form a single insulating foreskin, which is easily branched and connected. Reference numeral 13 denotes a branch-connected terminal. 14 is a stop,
A stopper hole 15 is provided, which is provided on the upper part and both sides of the box main body 1, and the box main body 1 is tied or hung to the hanging bolt 16 or the like in any direction of up, down, left and right. 17
Is a U-shaped transparent cover having stopper holes 18 on both sides. When the transparent cover B covers the transparent window B of the box body 1-B, the stopper protrusion 19 fits into the stopper hole 18 and is fixed.

[0007] The shape of the transparent window 2 or the transparent window B or the method of attaching the transparent plate 3 and the transparent cover 17 for covering the same and their shapes are not limited to the apparatus of the present invention.
Conventional technology such as an arbitrary shape and an arbitrary mounting device can be used.

As shown in FIG. 1, since the mouth opening edge portion 9 is located in the upper part deeper than the position of the binding elongate hole 7, the electric wire cable 10 can be directly bound, so that the material of the box body 1 can be either hard or soft. Can be united.

[0009]

The material used for molding the transparent joint box of the present invention is excellent in that it is difficult to see through after molding, but is economical, easy to mold, has self-extinguishing properties, and has few environmental problems. As a method of compensating for the difficulty of seeing through, the connecting portion of the connecting bundle housed in the box body 1 and the box body 1-B and the surrounding portion thereof can be seen through the window 2 at a position that can be seen from the outside.
Alternatively, a transparent window B is provided, and the transparent plate 3 or the transparent cover 17 is attached to that portion, and the wire connection portion of the stored wire bundle can be inspected through the front and side surfaces.

Naturally, even in the case of a resin material having self-extinguishing properties, if it is opaque, the transparent window 2 or the transparent window B of the present application is provided, and if the transparent plate 3 or the transparent cover 17 is attached thereto, the present invention can be used. The effect can be obtained without change.
