1 to 4 show an embodiment of the present invention. In the indoor wiring method according to the present embodiment, as shown in FIG. 1, a joint box 1 to which a power cable 3 from a distribution board and a plurality of wiring cables 4 are connected is installed in various places in an indoor area (for example, in each indoor zone). ). The joint box 1 is installed, for example, behind the ceiling so as to be inconspicuous.
A wiring device 5 having a device cable 6 is used, and a harness plug 11 is attached to a distal end of the device cable 6. A harness connector 10 is attached to the end of the wiring cable 4, and the wiring device 5 and the wiring cable 4 are connected by harness connection.

Various types of the joint box 1 are provided, and these are used in combination. As an example, for example, the one shown in FIGS. 2A to 2C is used. Here, the joint box 1a shown in FIG. 2 (a) is used for sending wiring by branching the power supply line into three, and is used for sending wiring to the joint box 1 in another zone, or as shown in FIG. An outlet as a wiring device 5 is connected to each branch end. In the drawings, W indicates a voltage side, L indicates a ground side, and an earth mark indicates a ground pole.

A joint box 1b shown in FIG. 2 (b) connects a feed wiring, a load connecting wiring device 5 and a switch 9 for controlling the load 7, respectively. The load 7 is a lighting device provided on the ceiling, and a hooking ceiling is used as the wiring device 5 for connecting the load. The lighting device is turned on and off by a switch 9 provided near the door 30 at the entrance of the room. It is used when doing.

The joint box 1c shown in FIG.
Is connected to a wiring device 5 for connecting a load and a plurality of switches 9 for controlling the load 7, respectively. In the case of FIG. An outlet for connecting a lighting device is used as the wiring device 5 for connecting the load, and the switch 9 is connected to the switch 9 for operating the lighting device on the ceiling provided near the door 30 at the entrance of the room. The one provided continuously and the one provided on the wall near the bed 31 are used. By configuring a so-called three-way circuit, the bed lighting can be turned on and off by any of the switches 9. It is used when doing so.

Each of the joint boxes 1 is provided with two connecting portions 8 on both end surfaces. When the core wires of the power supply cable 3 and the wiring cable 4 are inserted into insertion holes formed in the connecting portions 8, the joint boxes 1 are provided inside. The terminal plate and the lock spring have a so-called quick-connecting terminal structure in which the core wires of the cables 3 and 4 are elastically held and connected. When the release button is operated with a tool or the like, the cables 3 and 4 can be removed. I can do it. The quick connection terminal structure is well known in this type of wiring device, and a detailed description thereof will be omitted.

In the above case, the case where the joint boxes 1a to 1c are individually formed and arranged side by side as shown in FIG. 1 at the time of use has been described. However, the joint boxes 1a to 1c are integrally formed. May be. FIG.
1 shows a circuit configuration of the joint box 1 having an integral structure. In the case of the joint box 1, the power supply sides of the joint boxes 1a to 1c are commonly connected. However, in some cases, the circuit of each of the joint boxes 1a to 1c shown in FIG.

Next, a description will be given of the harness connector 10 and the harness plug 11 attached to the respective ends of the wiring cable 4 and the device cable 6 of the wiring device 5. In the present embodiment, the harness connector 10 is attached to the tip of the wiring cable 4 and the harness plug 11 is attached to the tip of the instrument cable 6 of the wiring instrument 5 such as an outlet or a hook-and-loop ceiling.

The harness plug 11 is provided with a recess at the tip, and has three plug blades in the recess. The harness connector 10 has a projection at the tip to be fitted into the recess of the harness plug 11. In addition, a blade receiving spring to which the blade of the harness plug 11 inserted through the blade insertion hole formed on the distal end surface of the protrusion is connected is provided. here,
A quick-connecting terminal similar to that of the joint box 1 is housed inside the rear end of the harness connector 10.
The core wire of the wiring cable 4 is inserted into the insertion hole of the connection portion formed on the rear end face so that the connection of the wiring cable 4 can be performed in a quick connection method. Note that the harness plug 11 is attached to the appliance cable 6 of the wiring appliance 5 in advance. On the upper surface of the harness plug 11, a lock piece 12 for fixing the connection state of the harness connector 10 is provided.
The harness connector 10 can be removed by releasing the fixed state of “0” .

If the wiring cable 4 and the appliance cable 6 are connected using the harness connector 10 and the harness plug 11 as in the present embodiment, the construction is facilitated. That is, in a condominium where the layout of the room and the installation location of the wiring equipment 5 are fixed, if the harness connector 10 is attached to one end of the wiring cable 4 having a predetermined length, the harness connector 10 and the harness plug 11 This is because it is only necessary to make the connection with the connection, and the connection work becomes easy. Further, if the joint box 1 is previously installed in various places in the room, the indoor wiring can be freely performed by relaying between the joint box 1 and the wiring device 5 with the wiring cable 4. It is possible to easily cope with a case where the floor plan is changed or a case where the installation location of the wiring device is changed.

The above-described harness connector 10 and harness plug 11 may have a structure other than those described above. However, it is preferable that the harness connector 10 or the harness plug 11 connected to the wiring cable 4 has a structure that can be connected by a quick connection method. That is, when changing the layout or changing the installation location of the wiring device 5, the wiring cable 4 can be easily replaced when the length of the wiring cable 4 needs to be changed.

In the above description, the case where indoor wiring is performed by ceiling wiring has been described. However, the present invention relates to floor wiring using a double floor structure floor called a so-called system floor applied to an office or the like. It can also be applied to wiring using walls and walls, and also to internal wiring in furniture such as OA panels.
