Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information communication connection device installed in a house for communication and video distribution, and to an external input device such as an outdoor antenna, an intercom or a telephone service line, or to information communication. The present invention relates to a technique for wiring between a connection device and each room.

[0002]

2. Description of the Related Art The wiring of a plurality of video and communication systems provided in each dwelling unit of a general detached house or apartment house is usually determined at the time of design according to a layout or the like, and wired at the time of building construction. So-called fixed wiring is provided. In the video system, there are terrestrial TV, BS, CS, CATV, etc. Each of which uses a coaxial cable to pass wiring from dedicated information communication connection equipment (hereinafter referred to as distribution system) to terminals provided in each room. Is distributed to the terminal.
In the communication system, there are an analog / digital (ISDN) telephone line, a LAN, and the like. Like the video system, a metal (copper) cable is distributed to each room from each distribution system. In addition, a wire connecting the door phone and the interphone is provided, and the phone and the wire may be connected in some cases.

[0003]

In the above-mentioned distribution system, in the video system, between the antenna and the room in which the television is installed, and in the communication system, between the drawing-in unit and the room in which the telephone is installed, independently of each other. It was provided in a different place. For this reason, each distribution system exists at a plurality of positions, and a plurality of wirings are distributed from each distribution system, so that the wirings are complicated. Also, at the time of building construction, construction methods that minimize construction costs and man-hours have not been established, and specifications for each construction site existed. As described above, the distribution system, wiring installation, and wiring method have not been standardized.

In addition, the above wiring is required to be installed inside the wall during construction.
If it is concealed on a ceiling or the like, it cannot be seen from the outside, so that it does not impair the aesthetic appearance, and since the wiring is not exposed, the wiring is not damaged. However, when adding wiring, it is difficult to hide the wiring inside the wall or on the ceiling. Usually, the wiring is extended along the wall, the wiring rail is drawn on the floor, and the hole for passing the wiring through the wall. It was necessary to penetrate through the wire, and the work of adding wires was difficult. Then, the appearance of the interior is impaired, for example, the wiring becomes visible after the wiring is added, and when the rail is pulled on the floor, the foot may trip. Furthermore, when the entire wiring of the fixed wiring is replaced, it is necessary to remove the wiring and then fix it again, so that the work is extremely difficult.
As described above, the housing has not been designed so far in consideration of the work of adding and replacing wiring.

[0005] Further, as described above, in a conventional ordinary house, in the video system, terrestrial TV, BS, CS, CAT
V. In the communication system, analog / digital (ISDN) telephone lines have been introduced, but there is a great possibility that future media / communication lines will increase. For example, in the near future,
Naturally, it is conceivable that BS digital broadcasting, optical cable communication, construction / extension of a LAN, and the like are necessary for ordinary houses. For example, in the case of an optical cable, it is necessary to re-wire the wiring from the beginning, and in the past, the room where the television and the telephone were installed was almost fixed, but in the future personal computers will become popular as personal computers spread. It is possible to watch a television or a video to be distributed, and it is possible to operate a personal computer in an arbitrary room. Therefore, a terminal may be provided in each room. Thus, in anticipation of such future expansion of wiring, it is conceivable to prepare a large number of wiring that is not necessary immediately after construction at the time of construction, but the initial cost is high. As described above, it is desired to be able to sufficiently cope with the need for additional wiring in the future.

[0006]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. That is, as described in claim 1, a box in which an information communication connection device for communication and video distribution can be installed, a primary pipe and wiring from the box to an external communication medium, and An object of the present invention is to configure a multimedia-compatible piping / wiring system including secondary-side piping and wiring passing to a terminal connection outlet provided in each room.

According to a second aspect of the present invention, the primary pipe and the secondary pipe have a pipe inner diameter that allows a plurality of incoming lines for communication and video distribution wiring.

According to a third aspect of the present invention, the primary side pipe and the secondary side pipe are arranged under the ceiling and inside the wall.

According to a fourth aspect of the present invention, the terminal connection outlet is selectively used depending on the number and type of terminals.
