Description

Description: TECHNICAL FIELD The present invention relates to provision of an information communication wiring line useful as a backbone (infrastructure) of an information communication line in a building or the like.

[Conventional technology]

In recent years, many buildings tend to be intelligent, and the information communication paths in such places are becoming more and more complicated.

By the way, the wiring for information communication in buildings such as office buildings, which have advanced information technology, mainly consists of the intermediate wiring installed on each floor from the main distribution board MDF attached to the PBX PBX installed in the basement. It was installed on the appropriate floor and a telephone (voice) line wiring path configured by connecting the board IDF to the wiring material, that is, a link cable, and wiring from the intermediate wiring board IDF to the telephone installed in the room. Host computer
It is occupied by data lines, etc. that are constructed by connecting data link cables from the CPU to the terminals installed on each floor.

However, in the case of constructing such a wiring path, conventionally, it was not decided at the time of completion of the building, and after the resident was decided and the arrangement plan of the equipment was decided, corresponding to the arrangement of those equipment, the link cable Wiring is common,
This method is known as the post wiring method.

[Problems to be Solved by the Invention]

According to the post-wiring information communication wiring path, the main wiring, which needs to be updated each time a resident is determined, is complicated and has a large amount of wiring. It was not possible to carry out flexible wiring enough to accommodate the addition or relocation of terminals.

As a result of intensive research to solve the above problems, the present invention is an information transmission system mainly for weak electric wiring (telephone system, data system, still image, etc.) In light of the fact that it is a low-speed system (several kb to 4 Mb / S), and in view of the fact that these information and communication wiring lines can be integrated, we will provide information and communication wiring lines that are prefabricated backbones. It was done.

[Means for solving the problem]

Means for solving the above-mentioned problems of the present invention is, in a building or other building, configured between a main terminal board provided on a predetermined floor and terminal boards provided on other floors and between terminal boards on each floor. In the information communication wiring path, a metal wire with an insulation coating having a conductivity sufficient to function as a ground bus is used as a support wire to electrically ground it to the main terminal board, and the metal wire with the insulation coating extends in the longitudinal direction. The grounding wire that splices into the terminal board on each floor is branched and connected at a predetermined interval, and the link cable between the terminal boards on each floor and the main terminal board are connected in the longitudinal direction of the metal wire with insulation coating as a shaft. A link cable between the terminal board on each floor is attached and fixed at arbitrary intervals.

・ It is fastened in a tightly bound manner to form a predetermined information communication wiring path.

Some of the many plastic bands are tightly bound in the vicinity of the branch connecting portion 5 between the insulating coated metal wire 1 and the ground wire 2 so that a large tension is applied to the bump-like portion of the branch connecting portion 5. It can be used as a stopper to prevent the link cables 3 and 3'which cannot be broken. In the figure, 1 indicates the lateral pull-out length on each floor of the link cables 3 and 3 '.

Such a cable as a unit is wound around a drum or the like before being shipped.

Figure 2 shows the wiring status of the link cable between the main terminal board MDF and each terminal board IDF on the vertical shaft in the building. From the main terminal board MDF, 8 pairs of link cables 3 are connected to each terminal board IDF on each floor. The link cables 3 are connected to the terminal board IDF on each floor. In addition, each pair of terminal boards IDFs adjacent to each other is connected by one pair of 8 pairs of link cables 3 ′.
