BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor electric wire which is routed under the ceiling or under the floor of a general house to connect lights, switches, outlets or the like to each other.
More specifically, the present invention relates to a composite type indoor assembled wire in which a mold type assembled wire and a plug connector type assembled wire are combined and integrated.

[0002]

2. Description of the Related Art For example, when a general house is constructed, a lighting device, a switch, an outlet, or the like is connected to each other by an electric wire cable for each room to form a predetermined electric circuit. However, it is not an easy task for a worker to lay an electric cable around a narrow ceiling or under the floor of a general house and then connect the ends of the electric cable to each other by fitting a connector to form a predetermined electric circuit. . Further, if the portions where the electric cables are connected to each other are not reliably insulated, there is a possibility of electric leakage and a fire.

Therefore, conventionally, a wire cable for connecting a lighting device, a switch, an outlet or the like to each other is previously cut into a predetermined length, and the wire cable is connected to each other so as to form a predetermined electric circuit. Is stored in the housing. After that, by molding using a resin material or the like and sealing it in the housing, a completely insulated molded electric wire is formed.

An example of the above-mentioned molded type indoor assembled electric wire is disclosed in Japanese Unexamined Patent Publication No. Hei 5-260624 and Japanese Utility Model Laid-Open No. 5-75.
967 and the like. These mold type assembled wires will be described with reference to FIGS. 5 to 8. As shown in FIG. 5, in the molded combined electric wire 60, the ends of a plurality of electric wire cables 62 are inserted inside the disk-shaped housing 61. In addition, the insulated electric wires 6 of the electric wire cables 62 associated with each other to form a predetermined electric circuit.
3 is connected by crimping a conductor portion whose tip is peeled off by a ring sleeve 64. Then, this connecting portion is resin-molded inside the housing 61 to be hermetically sealed and completely insulated.

In order to actually carry out indoor wiring using this mold type assembled electric wire 60, first, the bolt insertion hole 66 penetratingly provided in the central portion of the housing 61 is inserted into a bolt vertically provided on the ceiling or the like. Then, the housing 61 is fixed to the ceiling or the like. Then, the plurality of electric cables 62 extending from the housing 61 are respectively routed toward the switch, the lighting, and the like, and the ends thereof are connected to the switch, the lighting fixture, the outlet, and the like.

As shown in FIG. 6, a wiring system diagram 160 schematically shows an electric circuit formed by the mold type combined electric wire 60 shown in FIG. 5, and a plurality of wiring lines extending from a housing 61 located at the center in the figure. One of the electric wire cables is connected to the power source 161. Other electric wires and cables include a switch 162, an electric lamp 163, a fluorescent lamp 164, and a ventilation fan 16.
5, wall-mounted lighting 166, outlet 167, etc. are connected. The electric light 163 and the like can be turned on and off by operating each switch.

Next, a mold type indoor assembled wire 70 of a type different from the mold type assembled wire 60 will be described. As shown in FIG. 7, the molded indoor combined electric wire 70 has a substantially rectangular parallelepiped housing 71, and the electric wire cables 72 to 76 connected to the housing 71 have a small number of electric wires. Mold type assembled wire 6 described above
It has the same configuration as 0. As shown in FIG. 8, in the system diagram 170, the electric wire cable 72 of the mold type electric wire assembly 70 is connected to the power source 172, and the other electric wire cables 73 to 76 are connected to the four fluorescent lamps 171. Is wired so that

As described above, since a predetermined electric circuit is formed in advance in the above-mentioned molded type combined electric wire 60 and molded type indoor combined electric wire 70, the electric wire cable of this molded type combined electric wire is laid at the construction site. The wiring work can be completed simply by connecting the cable to a switch or the like. Therefore, this molded electric wire assembly is of high quality and relatively inexpensive.

On the other hand, a connection box for indoor wiring, in which the indoor wiring can be formed into an arbitrary electric circuit, is disclosed in Japanese Utility Model Laid-Open No. 3-307.
No. 20, for example. As shown in FIG. 9, the indoor wiring connection box 80 has a plurality of plug-in connectors 83 mounted on a substrate 82. Electric wire cable insertion hole 84 provided in this insertion connector 83
When the conducting wire 86 of the electric wire cable 85 is inserted therein, a terminal fitting (not shown) connects the electric wire cables 85 to each other. Further, when the lid 81 is attached to the substrate 82, the lid 81 covers the sheath portion of the electric wire cable 85 to the substrate 8.
It is configured to be pressed and fixed to 2.

As one wiring example, as shown in FIG. 10, the crossover wire 1 is provided between the plurality of plug-in connectors 181 and 182.
The lighting 1 connected to the power source 187 by operating the switch 183, for example, by connecting the lights 85 and 186.
It is possible to form an electric circuit capable of turning on / off each 84. Therefore, by using this indoor wiring connection box 80, it is possible to easily change to a desired electric circuit simply by changing the wiring of the crossover. It is also possible to form a desired electric circuit by using a branch terminal instead of this crossover wire.

[0011]

However, in the above-mentioned mold type combined electric wires 60 and 70, since the electric circuit is preset, for example, when a design change such as the addition of a switch is made, the mold type electric wires are molded. There is a problem in that it is necessary to replace the assembled electric wire with another one completely, which requires too much work.

On the other hand, in the above-mentioned indoor wiring connection box 80, a plurality of materials such as electric cables and plug-in connectors must be individually brought to the work site, and complicated material management is required. There is a problem that it leads to cost increase. In addition to the labor required to wire the crossovers while looking at the circuit diagram at the work site,
If the wiring of the crossover is wrong, there is a possibility that an electric circuit different from the design drawing may be constructed. That is, since the above-described molded type assembled wire and the assembled wire for indoor wiring have advantages and disadvantages as described above, it is possible to efficiently carry out the wiring work, and to further improve the design change of the electric circuit. It has been demanded.
