BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection device used for indoor wiring in condominiums and the like.

0002

2. Description of the Related Art In many cases, condominiums and the like have a roughly fixed floor plan, and therefore the installation locations of electrical outlets, switches, and other wiring devices are also roughly determined. Therefore,
Conventionally, the wiring cables were cut to a predetermined length at the factory depending on the installation position of the wiring equipment, and the wiring cables were connected in advance at the factory, and then the wiring cables were connected to the wiring equipment at the site. I was trying to do just that. A cable in which the above-mentioned wiring cables are connected in the factory as described above is called a branch cable, and as shown in FIG. 19, this branch cable 20 has a hook 20b on the upper surface of a joint part 20a that connects the wiring cable 4, The hook 20b is hung on the ceiling to perform wiring work on site.

0003

However, in the conventional indoor wiring method described above, the core wire of the wiring cable 4 whose sheath has been removed by step stripping or the like is inserted into the insertion hole formed in the wiring device, and the wiring cable 4 As the wiring equipment was connected to the equipment, there was a problem in that indoor wiring work was time-consuming, which became a big problem in the current situation where there is a shortage of electricians.

Another problem with the branch cable 20 is that it cannot be easily adapted to different wiring devices due to different room layouts. The present invention has been made in view of the above points, and its purpose is to provide an indoor wiring method that is easy to work with and can be easily adapted to cases where different wiring devices are installed. .

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention consists of a plurality of blocks according to the type of wiring equipment or the method of use, etc., and each block is detachably connected, and a power cable is connected to the block. A first connection part that can be connected to a connector, and a plurality of second connection parts to which a wiring cable can be connected to a connector.

[0006] Furthermore, in order to standardize the zone pull box, each of the blocks described above may be formed into a module with a constant size and shape.

[0007]

[Operation] By configuring the present invention as described above,
By making it possible to connect power cables and wiring cables with connectors, making wiring work easier, and by configuring multiple blocks according to the type of wiring equipment or application, etc., indoor wiring This allows wiring to be done in accordance with indoor wiring by replacing blocks depending on the situation, making it easy to handle cases where different wiring devices are installed due to different room layouts, etc. be.

[0008]

[Embodiment] In this embodiment, a zone pull box 1 into which a power cable 3 from a distribution board 2 and a plurality of wiring cables 4 connected to a wiring device 5 are drawn is installed indoors as shown in FIG. Provided for each zone. As shown in FIG. 2, the zone pull box 1 has a box shape with an open front, is constructed by being embedded in a wall, and has a structure in which the open front is closed with a cover 6. A power cable 3 and a wiring cable 4 are drawn in through an introduction hole 7 formed in a side surface (or other surface may be used) of this zone pull box 1. Furthermore, a connecting device 8 for appropriately connecting the power cable 3 and the wiring cable 4 is housed in the zone pull box 1.

The connecting device 8 is formed by combining a plurality of blocks 9, as shown in FIG.
is formed into a substantially convex shape with constant dimensions and modularized.
The zone pull box 1 can be standardized. Each block 9 has a connecting part 11 (same structure as a harness connector) for connecting the wiring cable 4 etc. on the upper surface of the protruding part, and a connecting part 11 (same structure as a harness connector) is formed on the upper surface of the protruding part, and a connection part 11 between the blocks 9 is formed on both sides to be joined when connecting the blocks 9. Connection parts 10a, 10b to be connected
(same structure as a harness connector and a harness plug) ), the power cable 3 is connected to the connection portion 10a on the side surface of the block 9 which is the endmost block when the blocks 9 are combined. Note that a harness connector 12 is attached to the tip of the power cable 3 to be connected to the connection portion 10a. Each block 9 is formed independently of one that constitutes an outlet circuit and one that constitutes a switch circuit, and the switch circuits are formed in a wide variety of types depending on the method of use. An example thereof is shown in FIGS. 6 to 9.

FIG. 6 shows an outlet block 9a. This outlet block 9a has four connecting portions 11, and two sets of connecting portions 11 arranged side by side are connected to connecting portions 10a and 10b formed on both sides. The terminals are connected in series, and the upper and lower sets of connection parts 11 are connected in parallel, and the harness plug 13 attached to the tip of the wiring cable 4 connected to the outlet 5a is connected to each connection part 11. It is set to connect.

The switch block 9b shown in FIG. 7 also has four connection parts 11, each having two connection parts 1 arranged vertically.
A harness plug 13 attached to the tip of the wiring cable 4 connected to the switch 5b is connected to one side of the switch 1, and a harness plug 13 attached to the tip of the distribution cable 4 connected to the load L is connected to the other side. Connect (however, load L
is not directly connected to the connection device 8, but is shown in this way to make the circuit configuration of the switch circuit 9b easier to understand), and the switch 5b and the load L are connected between the line to which power is supplied. The configuration is connected in series.

The switch block 9c shown in FIG. 8 has three connection parts 11, a switch 5c is connected to two connection parts 11 arranged horizontally in parallel, and a load L is connected to the other connection part 11.
When connected, a three-way switch is constructed. Furthermore, the switch block 9d shown in FIG. 9 includes two connecting parts 11, and the firefly switch 5d is connected to the upper connecting part 11 in the figure, and the load L is connected to the lower side. This is used when the firefly lamp built into the switch 5d is turned on when the switch 5d is turned off.

[0013] If the block 9 is formed like this,
Indoor wiring can be performed by appropriately connecting necessary blocks 9 using connection parts 10a and 10b depending on the wiring equipment 5 installed in the zone. Therefore, it is possible to easily deal with the case where the wiring fixtures 5 to be installed are different because the floor plans of the rooms are different. By the way, in the connection device 8 where a plurality of blocks 9 are connected as described above, if all the connection parts 11 are formed in the same way, there is a possibility that the wiring device 5 may be connected to the wrong connection part 11. Therefore, in this embodiment, compatibility during circuit formation is taken into account to prevent faulty circuits from being erroneously connected.

For example, the outlet block 9a and the switch blocks 9b to 9d are not compatible with each other. Therefore, as shown in FIGS. 10 to 13, a protrusion 14 is formed on the inner surface of the receiving part 13a of the harness plug 13, which is the connection part 11 of each block 9a to 9d, and A recessed line 15 that fits into the protruding line 14 is formed on the circumferential surface of the insertion part 12a of the harness connector 12, and the outlet block 9a and the switch block 9b~
9d, the formation positions of the protrusions 14 and grooves 15 are different. For this reason, the outlet 5a is connected to the switch block 9.
There is no need to connect the switches 5b to 9d or vice versa to the outlet block 9a. However, for example, the outlet 5a with a ground terminal and the outlet 5a without a ground terminal are compatible, so in this case, the formation positions of the protrusions 14 and grooves 15 should be aligned as shown in FIGS. 10 and 11. It is possible to connect to either.

[0015] Also, for example, switch blocks 9b to 9d
Even if they are, there is no compatibility between them. Therefore,
In this case as well, the positions of the protrusions 14 and grooves 15 are made different so that only the corresponding switches 5b to 5d can be connected. In addition, the wiring cable 4 connected to the load L side
The harness plug 13 is also formed in the same manner. By the way, although the switch block 9d is not illustrated,
In the same way, it is ensured that there will be no accidental connection. Furthermore, even when the ratings are different, incorrect connections can be prevented in the same way. Further, in the above case, the number of protrusions 14 and the number of grooves 15 is one, but a plurality of them may be used.

FIG. 4 shows an example of wiring in a zone. As described above, the wiring cable 4 connected to the outlet 5a or the switches 5b to 5d may be directly connected to the connection device 8 of the zone pull box 1 (FIG. 14(a),
(b) shows the wiring cable 4 connected to the vertical and horizontal outlets 5a, and FIG. If the wiring cable 4 is away from the box 1, instead of connecting the wiring cable 4 directly to the connection device 8, the cable 16 for the next relay is connected.
Or, a branch joint connector 17 is used.

As shown in FIG. 16, the relay cable 16 has a harness plug 13 attached to one end and a harness connector 12 attached to the other end. Note that the harness plug 13 and harness connector 12 of this relay cable 16 are also provided with a structure to prevent the above-mentioned erroneous connection. As shown in FIG. 18, the branch joint connector 17 branches the wiring drawn out from the zone pull box 1 with the relay cable 16, and is one connection to which the harness connector 12 of the relay cable 16 is connected. It includes a portion 17a (same structure as the harness plug 12) and three connecting portions 17b (same structure as the harness connector 13) to which the harness plug 13 is connected, and can be branched into three at most.

By using the relay cable 16 and the branch joint connector 17, wiring can be performed freely depending on the installation location of the wiring device 5, and since it is a connector connection, the connection work can be easily performed. . In addition, although the above description explained the wiring only on a wall surface, this Example can of course be applied also to the wiring fixture 5, such as the hook ceiling 5e shown in FIG. 17 arrange|positioned on a ceiling surface.
