Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the provision of an information communication wiring path that is used as an infrastructure infrastructure for information communication lines in buildings such as buildings.

[Conventional technology]

In recent years, many buildings are becoming more intelligent, and the information and communication lines in these places are becoming increasingly complex.

Now, in buildings where information technology has advanced, especially office buildings, information and communication wiring is mainly carried out from the main distribution board MDF attached to the private branch converter PBX installed in the basement etc. to the intermediate distribution installed on each floor. The telephone (voice) line wiring path, which is constructed by connecting up to the m-board IDF with wiring materials, that is, link cables, and wiring from the intermediate distribution board IDF to the telephone installed in the room, is installed on the appropriate floor. It is dominated by data lines, etc., which are connected by data link cables from post-computer CPUs to terminals installed on each floor.

Conventionally, when configuring such a wiring path, the decision was not made at the time the building was completed, but after the tenants were decided and the equipment layout plan was determined, the link cables were connected in accordance with the equipment layout. This method is commonly known as the post-wiring method.

[Problem to be solved by the invention]

However, according to the post-wiring method of information communication wiring, it is necessary to update the main wiring each time a tenant is decided, which increases the complexity and amount of main wiring.
There was a risk of incorrect wiring, and the wiring could not be flexible enough to accommodate the addition or relocation of terminals.

The present invention was developed as a result of intensive research to solve the above problems.
These are information transmission systems (targeting telephone systems, data systems, still images, etc.) that are mainly based on light electrical wiring, and are overwhelmingly medium-low speed systems (several kilobytes to 4 Mb/s). In view of the fact that these information communication wiring paths can be integrated, we have decided to provide an information communication wiring path with a prefabricated core.

[Means to solve the problem]

Means for solving the above-mentioned problems of the present invention is provided in a building such as a building, by connecting terminal boards between a main terminal board provided on a predetermined floor and terminal boards provided on each other floor, and between terminal boards on each floor. This is an information communication wiring path that is connected to a main terminal board by using an insulated metal wire with conductivity sufficient to function as a ground bus as a support wire, and conducts grounding to the main terminal board. The grounding wires that connect to the terminal boards on each floor are branched at predetermined intervals, and the link cables between the terminal boards on each floor and the main terminal board are connected in the longitudinal direction around the same insulated metal wire as the axis. Link cables are attached to the terminal boards on each floor and are tied and fixed at arbitrary intervals.

There is a wiring system for

Therefore, the telephone wiring system was replaced with the main terminal board MDF.
An iPBX is installed, and wiring is made from the terminal board IDF on each floor to each telephone in the room. On the other hand, in the data wiring system,
Wiring is done from the terminal board PP on each floor to the equipment in the room. Furthermore, as appropriate connections between terminal boards IDFs between each floor, between PPs, or between IDFs and PPs,
Predetermined network wiring is in place.

Now, the information communication wiring path of the present invention is configured by combining the link cables between each terminal board in this way.

In other words, as specifically shown in Figure 1, a metal with an insulating coating has conductivity that is a must-have for a ground bus! 1 is used as a support wire, and the grounding wire is connected to the terminal board on each floor at a predetermined interval in the longitudinal direction.2. 2. 2... are branch-connected, and with this insulated metal wire as the axis, a link cable 3.3' between the terminal boards is attached, and the wires are tied and fixed with plastic bands 4, 4, 4... at arbitrary intervals. This constitutes a predetermined information communication wiring path.

In addition, by tightening some of the many plastic bands in the vicinity of the branch connection part 5 between the insulated metal wire l and the ground wire 2, a large tension is applied to the knob-like part of the branch connection part 5. It can be used as a stopper for preventing slippage of the link cables 3, 3', which cannot be broken. l in the figure is link cable 3.3'
Indicates the extra length of horizontal draw for each floor.

Such cables are wrapped as a unit using drum winding or the like and then shipped.

Figure 2 shows the wiring status of the link cables between the main terminal board MDF and each terminal board IDF in the vertical shaft in the building. From the main terminal board MDF, 8 pairs of link cables 3 are connected to the terminal boards IDF on each floor. The number of link cables 3 corresponding to the number of link cables 3 is extended, and each link cable 3 is inserted into the terminal board TDF on each floor. In addition, each adjacent terminal board IDF is connected with one link cable 3' of 8 pairs, and the insulated metal wire l is suspended at its upper end and suspended within the vertical shaft. Connect the lower end of the metal wire 1 to the ground terminal of the main terminal board MDF to ground it, and connect the ground wire branched to the metal wire 1 to the terminal board TDF on each floor to connect the terminal board MDF and IDF. It forms the necessary grounding circuit between the

Note that the terminal board MDF and IDF are manufactured by, for example, Japanese Patent Application Laid-Open No. 60-4
It is preferable to arrange a large number of terminal modules on a common rail and connect selected terminals of these terminal modules, as shown in Japanese Patent No. 3991.

According to the present invention, in order to ensure that there is no erroneous connection and connection between these terminal modules and the link cable 3 (3'), the link cable 3 includes terminal magnets in the main terminal board MDF and terminal boards on each floor. A label 6 on which the terminal floor of the IDF is printed can be attached in advance.

According to the information communication wiring path of the present invention, which constitutes the main body as described above, as shown in FIG.
Based on the equipment layout plan, connect the crossover cable 7 to F, and connect the terminal device 8 through this crossover cable. Communication can be made to the terminal outlet 8'. Therefore, expansion or relocation of equipment can be handled by connecting cables to the terminal board.

Note that 9 is a crossing cable that connects the terminal board in the telephone system wiring path 10 and the terminal board in the data system wiring path 11.

〔Effect of the invention〕

As explained above, according to the information communication wiring path of the present invention, ■Unlike the conventional post-wiring method, the information communication trunk line can be laid in advance, resulting in significant savings in construction costs. .

■ Eliminates the man-hours required to pick up and lay multiple cables one by one on cable racks, etc. inside the vertical shaft.

■ Since the cables can be grouped, the space factor is improved, and the area occupied by the cables in the shaft room can be reduced and used effectively, which can be said to be effective in terms of disaster prevention.

■ By pasting identification labels on both ends of each cable at the factory, it is possible to eliminate the possibility of incorrect wiring.

- Since an insulated metal wire that only functions as a ground bus bar is used as a support wire, there is no need to lay a ground wire, and a simple ground circuit can be obtained.
