DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for connecting indoor wiring, which facilitates rearrangement of wiring circuits for 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, wiring is completed only by connecting to the external connection terminal 39, and the operation of each electric appliance is performed at 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 connection part 1 of the electric wire shown in FIG. 6, a synthetic resin is injected into the joint cap 3, and products are manufactured one by one for each specified circuit. If the circuit is changed due to a change in the layout, the product must be disassembled and the electric wires 11 must be reconnected, and the operation is complicated and the reliability is reduced. On the other hand, in the power distribution box 21 shown in FIG. 7, even if a change occurs in the circuit, the circuit change can be dealt with by appropriately changing the connection to the external connection terminal 39. Each of the wirings 45, 45, 45 connected to 39 must be manually reconnected each time. In a showroom or office where relatively frequent and quick layout change is required, the circuit can be more simply arranged. There is a need for a connection device that can be changed. 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 in which a wiring circuit can be easily changed even after wiring work.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a method and a device for connecting indoor wiring according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the wiring of the connection device according to the present invention, and FIG. 2 is a configuration diagram of the relay unit shown in FIG. The connection unit 51 is provided with a distribution unit 53, and a power line 56 from a switchboard 55 is connected to the distribution unit 53. A plurality of branch cables 57 are connected to the distribution unit 53, and the cables 57 are connected to a blinking mechanism (switch) and / or a load.

A relay section 61 is connected to the cable 57. As shown in FIG.
And a detecting unit 65 connected in parallel with the contact 63 to detect a voltage change at both ends of the contact 63. The contact 63 functions as a contact of a so-called relay that opens and closes the circuit according to the input signal. As the contact 63, a non-contact relay such as an electromagnetic relay or a semiconductor relay can be used. When detecting a change in current applied to both ends of the contact 63, the detection unit 65 is connected in series with the contact 63.

On the other hand, a control unit 69 is connected to the distribution unit 53 via a power supply unit 67. The control unit 69 is connected to a signal line 71 from a detection unit 65 provided in the relay unit 61. The control section 69 is connected to a contact 63 provided on the relay section 61 via a control line 73.

A data section 75 is connected to the control section 69. The data unit 75 controls opening and closing of a predetermined contact 63 by a control unit 69 based on a detection signal from a detection unit 65 included in the relay unit 61 connected to the switch 77 sent via the signal line 71. Connection patterns for connection. That is, by controlling the contact 63 by the control unit 69 based on the connection pattern stored in the data unit 75, a closed circuit of the switch 77 and the load 79 corresponding to the switch 77 is formed.

For example, a switch 7 is connected to the first cable 57a.
7, when this switch 77 is closed,
A detection signal is sent to the control unit 69 by the detection unit 65 constituting the relay unit 61 connected to the switch 77. Based on this detection signal and the connection pattern stored in the data part, the control part 69 closes the contact 63 of the relay part 61 connected to the corresponding cable 57, for example, the second cable 57b, and Power can be supplied to the connected load 79.

A writing section 80 is connected to the data section 75. The writing section 80 is for writing storage data to the data section 75. Further, an input / output unit (such as a connector) 82 for inputting write data is connected to the writing unit 80. The connector 82 is exposed and attached to the outside of the connection device 51. An external data transmission unit 84 can be connected to the writing unit 80 via a connector 82. The data transmission unit 84 stores the updated connection pattern created in advance and transfers the connection pattern to the writing unit 80.

When the wiring of the indoor wiring is performed using the wiring device 51, the position of the electric appliance to be operated in series is
Each of the cables 57 is routed, and after completing the interior work, various electric appliances are connected to each cable 57.
When a new connection device 51 is attached, an electric appliance to be connected to each cable 57 is specified, and a connection pattern based on the electric device is stored in the data unit 75. For example, the connection between the cable 57a and the cable 57b is specified so that the first cable 57a is connected to the switch 77 and the second cable 57b is connected to the ceiling lighting (load 79). On the other hand, the data section 75 includes a first cable 57a.
The connection pattern that allows the contact 63 of the second cable 57b to be opened and closed by the detection unit 65 is stored. Thereby, by closing the switch 77, the ceiling illumination connected to the second cable 57b can be flickered.

Further, in the connection device 51, even if the load is changed after the completion of the indoor wiring work, it is possible to easily cope with the change of the data unit 75 without changing the cable 57. It becomes possible. That is, in the above-described example, if it is desired to further control the blinking of the wall illumination (load 79) by a signal from the switch 77, the third cable 57c connected to the wall illumination based on the signal from the first cable 57a. The data in the data section 75 may be corrected so as to close the contact 63.

In order to rewrite the data stored in the data section 75, an update connection pattern created in advance is stored in the data transmission section 84, and the data transmission section 84 is connected to the connector 8
By connecting the connection pattern to the writing unit 80 of the connection device 51 via the connection unit 2 and transferring the connection pattern to the writing unit 80, the storage content of the data unit 75 can be rewritten.

As described above, according to the above-described connection device 51 and the connection method using the same, the data transmission unit 84 is connected to the writing unit 80 of the connection device 51, and the update unit that has been created in advance is used. The connection pattern is transmitted from the data transmission unit 84 to the writing unit 80.
Since the data stored in the data section 75 can be rewritten only by transferring the data to the wiring section, the circuit pattern of the indoor wiring can be easily changed.

Further, since the data transmission section 84 is provided separately from the connection device 51, it is not necessary to provide a keyboard for data input or the like in the connection device main body, and the connection device 51 is made compact accordingly. be able to. Furthermore, by providing the data transmission unit 84 separately, the connection device 5
The rewriting data can be created and stored in the data transmitting section 84 at any location without being restricted by the location where the device 1 is attached.

In the connection device 91 according to this embodiment, the data transmission unit 84 is connected to the power supply line 56 constituting the cable 57, and the writing unit 80 is connected to the distribution unit 53. Therefore, data from the data transmission unit 84 to the writing unit 80 is transmitted via the cable. As described above, since the existing cable is used as the data transfer path to the writing unit 80, data can be written without increasing the number of wirings. Also, data can be written by providing the data transmission unit 84 at an arbitrary location where a cable exists.
