The composite cable 12 for wiring is the same as the composite cable 11 for main line, and the coaxial cable 1 for TV signal is used.
2a, a pair cable 12b connected to a public line for telephone or data transmission, U used for LAN wiring, etc.
The TP cable 12c is a composite of cables having different signal transmission forms as one cable. And
The number of wiring composite cables 12 required for branching,
For example, four wiring composite cables 12-1 to 12-4 are prepared.

The unit housing 2 is provided with a coaxial cable distributor 3, a pair cable champ connector 4, and a UTP cable hub 5 in advance. The coaxial cable distributor 3 has a coaxial cable 1 of the composite cable 11 for the trunk line.
1a is connected to the in-side terminal, and the coaxial cable 12a of the plurality of wiring composite cables 12 is connected to the out-side distribution terminal.

The pair cable champ connector 4 includes:
Paired cables 11b of the trunk composite cable 11 are connected to terminals on the in-side, and a plurality of wiring composite cables 1 are connected.
The two pair cables 12b are connected to respective terminals on the out side. In the UTP cable hub 5, a UTP cable 11c of the trunk composite cable 11 and a UTP cable 12c of a plurality of wiring composite cables 12 are provided.
Each is connected to a predetermined hub terminal.

As described above, the coaxial cable 11a, the paired cable 11b, and the UTP cable 11c of the composite cable 11 for the trunk line are converted by the branch connection unit 1 into the coaxial cable 12a of the plurality of composite wiring cables 12-1 to 12-4. ,
It is branched into a pair cable 12b and a UTP cable 12c. The plurality of branched composite cables 12-1 to 12-4 are wired to predetermined floors or rooms without using piping.

FIGS. 2 and 3 are diagrams showing specific examples of the embodiment. In the figure, the same parts as those in FIG. 1 are denoted by the same reference numerals, and detailed description is omitted. The unit housing 2 of the branch connection unit 1 is provided with a coaxial cable distributor 3, a pair cable champ connector 4, and a UTP cable hub 5, as in FIG. Code 7 is UTP
This is a power cord of the cable hub 5.

As shown in FIG. 3, the unit housing 2 is composed of a base member 2a and a cover member 2b, and has a mounting hole 2c at the center thereof for mounting on a floor or a wall surface by means of fixing means such as screws. I have. Also, the unit housing 2 includes
A plurality of inlets 2d for introducing the composite cables 11 and 12 are provided, and each composite cable is fixed in the unit housing by a clamp member 6 (shown in FIG. 2). The unit housing 2 can be formed by molding a synthetic resin or drawing a metal plate.

In the specific example shown in FIG. 2, the branch connection unit 1 is provided with insertion ports into which three composite cables are inserted respectively on the upper side and the lower side of the figure. An example of connection is shown. The number of composite cables to be connected is not particularly limited, and depends on the form of branching.
The size of the unit housing and the number of insertion ports can also be appropriately selected.

As the composite cable 11 or 12, the composite cable 21 disclosed in JP-A-2000-123648 shown in FIG. 5 can be used. The same composite cable can be used as the composite cable 11 for trunk and the composite cable 12 for wiring. However, since the transmission amount of the composite cable for wiring is smaller than that of the composite cable for trunk line 11, an unused conductor pair is generated among the plural pairs of conductor pairs 23a of the pair cable 23 and the plural pairs of conductor pairs 24a of the UTP cable 24. Sometimes.

Therefore, the composite wiring cable 12 is
The number of conductor pairs 23a of the paired cable 23 and the number of conductor pairs 24a of the UTP cable 24 can be reduced as compared with those used in the trunk composite cable 11. For example, as the wiring composite cable 12, these conductor pairs may be one pair, or 0 or 2 or more pairs depending on the room to be wired. Alternatively, a composite cable may be formed by combining different types of cables such as a power supply cable and an optical fiber cable which are not shown in FIG.

The specific example shown in FIG. 2 is an example in which one composite cable for trunk line 11 branches into five composite cables for wiring 12-1 to 12-5. Composite cable for wiring 12-1 to 12-3
Are wired to rooms 1 to 3, respectively, the composite wiring cable 12-4 is wired to the living room, and the composite wiring cable 12-5 is wired to the bedroom. Distributor for coaxial cable 3,
Each cable of the trunk composite cable 11 is connected to the in-terminal of the pair cable champ connector 4 and the UTP cable hub 5, and the wiring composite cables 12-1 to 12-5 are connected to the out-terminal. Are connected.

As a basic usage of the branch connection unit 1, as shown in FIG. 2, a plurality of out-side wiring composite cables are connected to one in-side main cable composite cable. . However, it can be used in various other usage forms. For example, when a network is formed in an apartment house or the like, the composite cable 12-5 for wiring shown in FIG.
It is connected to the in side of the branch connection unit 1 of the next house. Less than,
Similarly, by sequentially connecting the branch connection units 1 of each house, networking can be easily performed.

In the case where the room 1 in FIG. 2 is divided into a large room and several small rooms (such as an office), and wiring is also performed in each small room, the wiring composite cable 12-1 is used. Another branch connection unit 1 may be connected to the subsequent stage to perform branch wiring.

It is to be noted that the number of the composite cable 11 for the main line is not limited to one, and the capacity of signal transmission on the composite cable for the main line can be doubled as two. In this case, for example, in FIG. 2, the composite wiring cable 12-5 for the bedroom is connected to the in side as a trunk cable, and is used for receiving signals from the outdoors.

The branch form or combination of wiring in the branch wiring unit 1 is determined by the connection settings in the coaxial cable distributor 3, the paired cable champ connector 4, and the UTP cable hub 5, and is determined in advance by the manufacturing factory. Is set. Therefore, at the construction site, it is only necessary to identify the composite cable for the main line and the wiring for each room. Then, each identified composite cable is wired to the connection port of each room without using piping.

[0030]

As described above, according to the present invention, a plurality of types of cables having different usage forms are all combined as a composite cable on both the in side and the out side of the branch wiring unit. The wiring to the room can be simplified, and the wiring work becomes easy. In addition, the branch wiring unit can set a branch pattern according to a branch form in a manufacturing factory in advance, can prevent occurrence of a connection error at a construction site, facilitate branch work, and facilitate quality control. .
