Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a connection branch portion for efficiently wiring a cable used for low-voltage indoor power wiring of a building, an apartment, a detached house, or the like.

[0002]

2. Description of the Related Art Conventionally, low-voltage indoor power wiring receives power drawn from the outside by a distribution board, and from there, it is wired to each room, each load point and switch according to the function of the building. It was At this time, if the wiring is directly connected from the distribution board to each load point / switch, the work is not only difficult, but also wasteful of cables and uneconomical. Therefore, in general, a method in which an appropriate number of load groups are grouped into one group and once wired from the distribution board to near the geometric center of this load group with a single cable, and then from there to individual loads Has been taken.

Therefore, a branch connecting portion for branching from one cable to a plurality of cables is required at this location.

In the past, this branch connection work was performed at the construction site of construction. However, the wiring work for low-voltage indoor power must be done by a worker after the building is completely finished, in a narrow ceiling, inside a wall, or in a duct. The work of stripping and connecting the coating takes time, the work efficiency is poor, and the reliability is poor. In order to improve this point, a method is beginning to be adopted in which only this branch connection part is created in advance in the factory and only wiring is connected to the load point / switch at the site.

FIG. 7 and FIG. 8 are typical ones. FIG. 7 shows a branch connecting device in which a plurality of cables are mounted in a box formed of a synthetic resin material in a bell shape.
The ends of the cables are connected in a suitable manner in the box, insulated, and the entire box is sealed with a curable resin.

FIG. 8 shows a disk-shaped or semi-disk-shaped branch connecting device, in which a plurality of cables are connected to each other and are radially wired, insulated, and then molded into a whole shape and injection-molded with resin. It was done. The advantage of this form is that it can be formed to be relatively thin compared to that of FIG. 7, so there are few restrictions on the place to install it in the ceiling or in the wall. It is also possible to form the branch connection device in a rectangular disk shape.

By using these branch connection devices, the low-voltage indoor power wiring work can be relatively easily realized even in a narrow space where the work environment is poor, regardless of the difference in the ability of the workers.

However, in these branch connection devices, a cable of a predetermined length is laid in advance from the branch portion and the end of the cable is connected to a load point or a switch. There is a problem that the length is not sufficient and extension is required afterwards, and there is a problem that if the wiring length of the cable is set as long as possible in order to avoid it, resources are wasted as much.

As one method of preventing this, instead of connecting a cable in the branch connection device to form a unit,
There is a branch connection device in which a plurality of plug-in connectors are connected to each other for the purpose of unitization.

FIG. 9 shows an example of this type of branch connection device. In this example, the branch connection device is divided into five sections, the first section is for power and feed (outlet),
The second section is for feeding (outlet), third to fifth
Section is for switches and loads. The side surface of each section is formed with an electric wire hole of a plug connector, and the other end of the cable whose one end is connected to the load side can be inserted without peeling the cover so that wiring can be performed without waste.

However, since this branch connection device is composed of a plurality of sections as described above and the function of each section is predetermined, there is a problem that the degree of freedom in use is small. In the example of FIG. 9, three feeds (outlets) and three switchable loads are fixed. In order to be able to select freely for any request, there is no choice but to increase the type of branch connection device or use multiple branch connection devices with the knowledge that some sections are wasted. Not necessarily economical.

In consideration of the above points, the present invention aims to realize a branch connection device for low-voltage indoor power wiring, which can realize wiring efficiently without waste, and which is suitable for the purpose of free wiring and branching. To aim.

[0013]

As described above, the conventional branch connection device has problems that there are many wiring and work losses and that there is no degree of freedom in connection. In view of this point, an object of the present invention is to realize a branch connection device for low-voltage indoor power wiring, which can realize wiring efficiently without waste, and which can be freely wired and branched suitable for the purpose. .

[0014]

In order to achieve the above object, the present invention provides a power wiring branch connecting device for branching wiring in low-voltage power indoor wiring and distributing it to load points and switches in a flat plate shape. It is characterized in that at least one functional unit having a connection configuration corresponding to the formed branch destination is laminated and integrated.

The functional unit is fitted to the plug connector means for connecting a plurality of cables provided on the side surface of the functional unit, the hooking means provided on the upper surface of the functional unit, and the hooking means provided on the lower surface of the functional unit. It is characterized by having a fitting means to do.

A decorative lid is provided above and below the stacked functional units.

There are two types of functional units: a switch functional unit and a power source / outlet functional unit.

The hooking means is used as a conductor for transmitting electric power between the functional units.

[0019]

According to the present invention, it is possible to realize a branch connection device for low-voltage indoor power wiring, which is capable of performing free wiring and branching suitable for the purpose by combining a plurality of functional units according to the purpose.
