DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for connecting indoor wiring, which facilitates rearrangement of wiring circuits when installing indoor wiring.

[0002]

2. Description of the Related Art In indoor wiring work, labor saving of on-site work,
Shortening of construction period and reliability of construction are required. One of the things that fulfills such a demand is, for example, the Japanese Utility Model Application 57-43.
There is a connection part of an electric wire described in Japanese Patent No. 570. FIG. 6 is an explanatory view of a conventional electric wire connection portion. The electric wire connection part 1 is provided with a synthetic resin joint cap 3 and a partition member 9 in which a plurality of electric wire division parts 7 are formed by radial partitions, and the exposed conductor connection part 13 of the electric wire 11 is provided in the electric wire division part 7. In addition to the arrangement, the electric wires 11 are fixed in each electric wire section 7 by the synthetic resin injected into the joint cap 3.

The connecting section 1 is manufactured by connecting in advance a necessary electric wiring circuit in a factory. Accordingly, in the indoor wiring work, the connection can be easily performed only by supporting the connecting portion 1 on a beam or the like and wiring the electric wire 11 to each designated load. In addition, since connection can be performed at the factory, reliable processing can be performed, and high reliability can be obtained.

[0004] On the other hand, in indoor wiring work, there is a case where a connection device (distribution box) in which connection parts are integrated into a unit is used to reduce labor on site work and shorten a construction period. A distribution box of this type in which a branching unit and a blinking unit are added to a distribution board, for example, described in Japanese Patent Application Laid-Open No. 4-289708 will be described with reference to FIGS. FIG. 7 is a block diagram showing wiring of a conventional connection device, and FIG. 8 is a wiring diagram showing an example of indoor wiring using the conventional connection device.

[0005] A distribution box with a branch circuit (power distribution box) 21 is supplied with power from a service line 23 via a power meter 25. A power distribution unit 33 including a drop-in switch 27 connected to the wattmeter 25 and a breaker 31 connected to a plurality of branch lines 29 branched from the power switch 25 is provided therein. The power distribution unit 33 further includes a branching unit 35 and a blinking mechanism (switch) 3.
7, and the external connection terminal 39 are connected. A branching means 35 is connected to each breaker 31, and a plurality of branching circuits 41 are formed here. The branch circuit 41 is wired to the external connection terminal 39 via a blinking mechanism 37 such as a tumbler switch.

[0008] In order to perform indoor wiring using the distribution box 21 configured as described above, as shown in FIG. 8, as shown in FIG. After the interior work is completed, the end of each cord may be processed and each electric appliance may be attached. And each wiring 45, 4
5 and 45 are extended to the position of the power distribution box 21, the wiring is completed only by connecting to the external connection terminal 39, and the operation of each electric appliance is performed in one place by operating the blinking mechanism 37 in the power distribution box 21. Will be able to concentrate.

According to the power distribution box 21, in the indoor wiring, it is only necessary to wire in advance to a position where the electric appliance is to be mounted by using a crossover wiring or the like, and to extend the extension line to the position where the power distribution box 21 is arranged. In this step, it is not necessary to adopt a construction method of arranging and branching the joint box while calculating the allowable amount of the terminal load of each branch circuit, and even a person who does not have the skill can easily perform the wiring. Wiring that matches the allowable load of the electric circuit terminal load is connected to the external connection terminal 39 in the distribution box 21 regardless of the interior construction work.
It could be done freely by appropriately changing the connection to.

[0008]

However, in the electric wire connection section 1 shown in FIG. 6, products must be manufactured one by one for each specified circuit, and mass production by standardization work cannot be performed. , Pre-production could not be performed. Further, when the circuit is changed due to the layout change, since the synthetic resin is injected into the joint cap 3 to seal and fix the electric wire 11, the connecting portion 1 has to be disassembled. On the other hand, the power distribution box 21 shown in FIG. 7 can be mass-produced and can cope with a circuit change by appropriately changing the connection to the external connection terminal 39 even when the circuit is changed. The circuit change is performed by each of the wires 45, 4 connected to the external connection terminal 39.
5, 45 must be done manually each time,
In showrooms, offices, and the like where relatively frequent and quick layout changes are required, there has been a demand for a wiring device that can change circuits more easily. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wiring method and a wiring apparatus for indoor wiring which are excellent in mass productivity and can easily change circuits even after wiring work.
