DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information wiring system used for telephone and data signal communication.

[0002]

2. Description of the Related Art Conventionally, in an office or a factory, an information wiring system using a twisted pair wire or a coaxial cable has been widely used for transmitting various information. The form of information transmitted by this type of system is not limited to analog signals such as telephone lines and facsimile,
It often includes digital signals from terminals. Further, the contents of information include all media such as audio signals, digital signals, and image signals. A system in which such various communication devices are configured as a network based on a unified architecture is an integrated information wiring system, and a star topology is generally adopted as the wiring topology.

FIG. 6 is an overall configuration diagram of an information wiring system according to a conventional example. Hub HUB and private branch exchange PBX
Is connected to the wiring switching board PB via the twisted pair wire TP, and the wiring switching board PB is further connected to the twisted pair wire TP.
A terminal T, a telephone TEL, and a printer PR are connected via an outlet O.

[0004]

However, in the information wiring system having the above-described structure, the cost of the operation of connecting the twisted pair wire TP and the connection work using the tool between the twisted pair wire TP and the outlet O are reduced. There was a problem that it took time.

[0005] In addition, there is a problem that the connection work of the modular jack and the modular plug to the twisted pair wire TP on the site requires skill and it is difficult to ensure the quality.

Further, when changing the position of the outlet O wired in advance, it is necessary to cut or extend the twisted pair wire TP and reconnect the outlet O using a tool, which is costly and time-consuming. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide an information wiring system capable of easily performing and changing wiring.

[0008]

According to the first aspect of the present invention,
As a communication cable, a plurality of types of communication cables of a predetermined length are used, and at both ends of the communication cable, modular connectors that enable connection between the communication cables are provided,
The outer surface of the modular connector is formed only of a convex curved surface that is outwardly convex, except for the vicinity of a connection portion between the connectors and a portion where a communication cable on the substantially opposite side extends. It is characterized by the following.

[0009]

According to a first aspect of the present invention, there is provided an information wiring system in which a communication device is connected to a wiring switching panel via a communication cable to transmit a signal. Using a communication cable, a modular connector that enables connection between the communication cables is provided at both ends of the communication cable. By connecting a plurality of types of communication cables of a predetermined length to each other, the communication cable after the connection is connected. The length can be freely extended or shortened to some extent, and the connection can be made simply by connecting the modular plug without using a connection tool. Further, since the outer surface of the modular connector is formed so as to include a convex curved surface which is outwardly convex except for the vicinity of a connection portion between the connectors, the convex curved surface portion has a recess in the wiring space. This makes it easy to prevent the modular connector from being caught around. Also, since the outer surfaces of the plurality of modular connectors are curved as compared with the conventional case where the outer surfaces of the modular connectors are flat, it can be said that the outer surfaces of the plurality of modular connectors are less likely to be caught by each other.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram showing an example of an information wiring system according to one embodiment of the present invention. Wiring switching board P
A terminal T, a telephone TEL, and a printer PR are connected to the secondary side of B via a twisted pair line TP1, TP2, TP3 of a predetermined length as a communication cable. here,
At one end of the twisted pair wires TP1, TP2, TP3, a modular jack MJ as a connector is provided, and at the other end, a modular plug MP as a connector is provided. A hub H is connected to the primary side of the wiring switching board PB via a twisted pair wire TP2 and a connection adapter A.
The UB and the private branch exchange PBX are connected. The connection adapter A is for connecting a hub HUB and a private branch exchange PBX to a modular jack MP provided on the twisted pair line TP2, and has modular plugs MP at both ends.
Having.

In this embodiment, at the time of wiring work, twisted pair wires TP1, TP2 and TP3 of three lengths are combined according to a desired cable length, and a modular jack MJ and a modular plug MP are used without using a tool. Is connected, a communication path can be secured. Also, when the cable length needs to be changed with the movement of the terminal T, the telephone TEL, the printer PR, etc., the wiring can be easily changed by adding or decreasing the twisted pair wires TP1, TP2, TP3.

FIG. 2 is a schematic diagram showing an example of an information wiring system according to another embodiment of the present invention. Ducts D1 to D12 as wiring spaces are installed in the building, and the ducts D1 to D12 are connected by duct connection parts d1 to d12. Twisted pair wires TP1, TP2, and TP3 are provided in advance inside the ducts D1 to D12, and a communication path is established by connecting the modular jack MJ and the modular plug MP inside the duct connection portions d1 to d12. To secure.

For example, a wiring switching board PB is installed near the duct connection d7, and the terminal T is installed near the duct connection d3.
Is installed, the duct connection parts d1, d2, d
At 3, d4 and d7, by connecting the modular jack MJ and the modular plug MP, the duct D1,
The wiring switching board PB and the terminal T can be connected via D2, D3, and D8.

Therefore, in the present embodiment, the twisted pair wires TP1, TP2, TP2,
By providing the TP3, it is possible to easily secure and change the communication path.

In the above description, the shape of the modular jack MJ may be such that the outer surface is formed in a curved shape as shown in FIG. 3A, or a substantially square cross section as shown in FIG. This is achieved by attaching a curved connector cover component to the modular connector in a retrofit manner. By doing so, it is possible to prevent a dent in the wiring space at the time of wiring work and pulling out of the twisted pair wires TP1 to TP3 and to prevent the twisted pair wires TP1 to TP3 from being caught between the existing twisted pair wires TP1 to TP3. The wiring work is performed smoothly.

FIG. 4 is a schematic diagram showing a wiring pattern in which a plurality of twisted pair lines TP1 to TP3 according to another embodiment of the present invention are combined. In the present embodiment, a predetermined wiring pattern is formed by combining a plurality of twisted pair lines TP1 to TP3 in advance, and the twisted pair line TP1 is formed.
TP3 is connected to a modular jack MP at one end and a modular plug MP at the other end.

For example, as shown in FIG. 5, when a wiring groove 4 in a building is provided, a plurality of twisted pair wires TP1 are set in advance in a factory or the like according to the shape of the wiring groove 4.
To TP3 to form a wiring pattern, so that the twisted pair wires TP1
It is only necessary to insert a wiring pattern combining TP3.

Therefore, by forming a wiring pattern by combining a plurality of twisted pair wires TP1 to TP3 at a factory or the like in advance, the twisted pair wires TP1
It is only necessary to arrange the wiring patterns formed by combining 1 to TP3, and the labor of construction can be simplified.
