Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combination indoor electrical wiring for use in buildings, particularly prefabricated houses, apartments, buildings, etc., and a method for manufacturing the same.

When wiring lights, outlets, etc. in a secondary building, remove the insulation from the wire ends on site according to the blueprint, and connect the conductors of the wires to each other using a crimp ring sleeve and a manual crimp bench. Each of the circuits was constructed in this way, and the connecting portions were further covered and insulated with vinyl tape, a PVC box, etc. (see Figures 1 and 2).

However, the connection is made using a crimp ring sleeve as described above, but the size of the crimp ring sleeve must be changed depending on the number of wires to be connected, making the circuit configuration complicated. became. In addition, the increase in the number of wires targeted led to the occurrence of conspiracy lines. In addition, since the connection work is done on-site, work efficiency such as wiring processing is extremely low, and depending on the experience of the worker, the accuracy of the work may vary, such as the mass of the connection work and the reliability of the connection itself. could not be kept constant. The present invention has been made in view of these problems, and an object of the present invention is to provide indoor electrical wiring and a method for manufacturing the same, which enables mass production of various types of wiring.

Make sure that all core wires of Z5 and Z6 are connected. Further, some of the cable core wires may be connected not only to the one-willow part but also to the pond side part. Also,
The combination indoor electrical wiring a configured as described above includes connection wires x. Y is bent into an arc shape to form a loop shape (including round shape, circle shape, etc.) and molded into a flat plate shape 18, and the cable Z is directed to each terminal device.

A sticker 19 or the like indicating the name of the terminal device to which each cable Z is directed is attached to the flat surface of the mold 18. The mold 18 may be placed as is or hung with a hook 20 provided in the center depending on the space available at the installation location. As described above, in the present invention, firstly, various wiring units of different systems are selected as appropriate, which are formed by connecting the unit wire portion of the connecting wire serving as the main line and the cables to be connected to each terminal device. A combination in which the unit electric wire portions of each wiring unit are arranged in series and their connection portions are crimped together, and a power supply cable is connected to any of the series connection portions of the unit electric wire portions, thereby providing the necessary circuit. Since the indoor electrical wiring has been configured, combined indoor electrical wiring that matches the type of building can be easily, quickly, and reliably obtained in a fan-flat state, and the power supply cable can be connected in series with the unit electric wire sections. Since the connecting wire can be connected to the optimal position of the connecting wire that is formed and becomes the main line, the connecting work is also easy.

We have developed a manufacturing method for combined indoor electrical wiring in which a wiring unit is formed by crimping the unit wire portions of connecting wires so that each conductor is connected, so that it is possible to use one type of crimp terminal and the wiring work is simplified. In addition, since each wiring unit can be produced in large quantities at the factory and then combined according to the specifications, it is possible to
Mass production becomes possible, and combined indoor electrical wiring with stable quality can be easily obtained.
