DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-home LAN wiring which enables use of LAN terminals at a plurality of places in a house and a LAN wiring unit used for the same. The present invention relates to a home LAN wiring and a LAN wiring unit in each dwelling unit which are suitable for enabling a LAN terminal.

[0002]

2. Description of the Related Art Due to the spread of information networks such as the Internet, the use of information networks is becoming common even in ordinary homes and small businesses called small businesses occupying apartment houses. Therefore, when constructing a new apartment house, it has become necessary to provide in-home wiring for an information network in addition to conventional electric wiring for commercial power.

In a large-scale apartment house, a server functioning as an Internet server is installed in the apartment house itself, and a LAN is provided to each dwelling unit through the server to provide a network environment to each dwelling unit. Has been done. In this case, a LAN drop-in line is laid out beforehand for each dwelling unit from the server, and in each dwelling unit,
In a living room, a study, a bedroom, or the like where an information terminal is considered to be used, an outlet for connecting a LAN terminal (LA in this specification)
N outlets) are provided, and a preceding home wiring for connecting the outlets to the LAN service line is provided.

[0004] Connecting a plurality of LAN outlets to a LAN service line wired to each dwelling unit is easily possible by installing a hub at the branch portion. Therefore, for example, if LAN outlets are to be installed in three places in each dwelling unit in advance, a hub may be installed at the position where the LAN service line is pulled in, and a preceding home wiring connecting the hub and each LAN outlet may be provided.

[0005]

However, installing a hub for each dwelling unit requires a certain cost. on the other hand,
Although the use of the Internet is becoming popular, the construction of a home LAN using a plurality of information terminals in a general home is still few. In particular, when the area of the dwelling unit is relatively small and the family structure is relatively small, as in each dwelling unit of an apartment house, there is little need to build a home LAN. Therefore, even if a hub is installed in each dwelling unit of an apartment house to provide an environment in which a home LAN can be constructed, very few homes actually use it. Therefore,
Providing a home LAN environment to each dwelling unit of an apartment house by the above means causes a large economic loss.

However, on the other hand, rapid development of information networks is expected, and changes in the family structure of residents of apartment houses must be taken into consideration. In addition, even if only one information terminal is used in each dwelling unit, it is necessary to provide an environment where it can be used at a desired location because the location where it is used differs depending on each dwelling unit. For this purpose, it is necessary to provide a LAN outlet and a preceding home wiring connected thereto at a plurality of locations in each dwelling unit.

In order to satisfy this need and the desire to be able to construct a home LAN, it is conceivable that a hub can be installed at the connection between the LAN service line and the home information wiring. However, for that purpose, it is necessary to provide some space in advance,
This kind of electronic equipment has a problem that progress is remarkable and its structure and size are drastically changed. In addition, it is necessary to install this type of device in a place where it is easy to check the operation, and there is a possibility that various functions will be added in the future, so it is anticipated how the device will be installed It is very difficult to do. A necessary condition is that when a user wants to change the hub to a new one, it is easily possible. Considering such a situation, it is not a practical method to provide a structure in which a hub can be installed at the entrance of the LAN service line because the structure may be rapidly obsolete.

An object of the present invention is to provide an economical and highly expandable technical means which satisfies the above various needs.

[0009]

According to the present invention, a LAN outlet for connecting an information terminal and an in-house information wiring are provided at a plurality of locations in each dwelling unit, and a LAN wiring unit is provided at a LAN entry cable entrance of each dwelling unit. To enable selection of the use location when one terminal is used by switching the connection of the LAN wiring unit, and to use a plurality of terminals by connecting a hub to a LAN outlet where the terminal is installed. It is also possible to construct a home LAN to perform the operation.

That is, the home LAN wiring of the present invention comprises:
LAN outlets 5 arranged at a plurality of locations, a LAN wiring unit 1 provided at one location, and a house wiring 6 connecting each LAN outlet 5 and the LAN wiring unit 1

It is connected to a LAN cable connection port 7b (other as claimed). The LA of the home wiring connected to the sending port of the LAN outlet
The connection end on the N wiring unit side is connected to a LAN cable connection port 8 connected to a LAN outlet to use another terminal. The use of the above-described patch cord 4 for connecting the ports in the LAN wiring unit is highly practical in terms of cost and expandability.

If a plurality of sender ports 7b are provided in each LAN outlet 5, it is possible to construct a home LAN using three or more terminals by installing one hub. Since it is considered that it is extremely rare that three or more terminals are installed in a relatively small dwelling unit having a small family structure, the number of LAN cable connection ports 7 provided in each LAN outlet depends on the receiving side. Say 1

The LAN outlets 5 are arranged in the living room, study, bedroom, etc. of each dwelling unit. Each LAN outlet 5 includes two 8-terminal ports 7 serving as LAN cable connection ports. This eight-terminal port is practically an RJ-45 jack since the connector of the LAN cable currently on the market is an RJ-45 plug. One 7a of the two 8-terminal ports 7 is a signal receiving side, and the other 7b is a sending side.

The wiring board 2 of the LAN wiring unit includes
Four eight-terminal jacks 8 and four four-terminal jacks 9 paired therewith are arranged. In addition, eight four-terminal connectors 10a and 10b for connecting cables are arranged corresponding to the respective jacks 8 and 9. Here, the four-terminal connector with the suffix a added to the code
The receiving side connector connected to the terminal jack 8, and the connector with the subscript “b” is the sending side connector connected to the four terminal jack 9. 4-terminal connector 10 on the receiving side
a and the terminals of the eight-terminal jack 8 are connected as shown in FIG. The connection like this is 10BAS
In the ET LAN connection, terminal number 1 out of 8 terminals,
This is because only four terminals 2, 3, and 6 are used.

The receiving side port 7a and the sending side port 7b of each outlet 5 are connected to the receiving side connector 10a and the sending side connector 10b of the wiring board by home wirings 6a and 6b, respectively. Eight terminal ports and wiring 6a, 6b or connector 1 on the receiving and sending sides of the outlet
The connection form between the contacts 0a and 10b is shown in FIG. 3, and the connection form between the terminals is the same as that shown in FIG. When using 10BASE-T LAN connection, it is practical to use an 8-core (UTP) cable for the home wiring 6.

An eight-terminal plug 13 is connected to a connection end of the LAN service line 3. The patch cord 4 has a four-terminal plug 14 connected to one end and an eight-terminal plug 1 connected to the other end.
5 is connected. In FIG. 4, the eight-terminal plug 15 is
The connection structure of a patch cord when a J-45 plug is used is shown. Patch cord 8-terminal plug 15 and LA
The eight-terminal plug 13 of the N lead wire must have the same structure. When the terminal is used only at one place in the house, the patch code 4 is unnecessary, but one patch code is required for each additional terminal.

In the embodiment shown in the figure, the sending port 9 of the LAN wiring unit is a four-terminal jack, but it may be the same eight-terminal jack as the receiving side.
A 6-terminal jack widely used under the name of a pin modular jack can also be used. In this case,
Naturally, the connector 14 of the patch cord 4 is also an eight-terminal or six-terminal plug.

In the above configuration, if the LAN drop-in wire 3 is connected to any one of the eight-terminal jacks 8 of the wiring board, the L connector connected to the corresponding receiving connector 10a is connected.
A terminal can be connected to the receiving port 7a of the AN outlet 5 for use. When the terminal is moved, the connection of the LAN service line 3 to the eight-terminal jack 8 of the wiring board corresponding to the destination may be changed.

If you want to use the terminal in two places,
The hub 1 is connected to the LAN outlet 5 to which the service line 3 is connected.
Then, a terminal 17 is connected to the outlet 6 and one of the cascade ports of the hub 16 is connected to the sending port 7b of the outlet. Then, the patch cord 4 connects the four-terminal jack 9 of the wiring board corresponding to this outlet to the eight-terminal jack 8 corresponding to the outlet to which the second terminal is to be connected. In this case, the two terminals are connected to the hub 1
6 is cascade-connected to the LAN drop-in line 3 via the LAN 6, a home LAN can be constructed between the two terminals.

To further increase the number of terminals, as shown by the imaginary line in FIG.

Connect to As described above, according to the means of the present invention, when adding the second and subsequent terminals, it is necessary to prepare a number of hubs corresponding to the number of added terminals, or use two or more terminals as described above. Is rare, so it is generally more economical than installing a hub in every dwelling unit in advance. Further, since the installation and replacement of the hub are easy, it is possible to use the hub according to the user's preference and the progress of technology.

FIG. 5 is a view showing a second embodiment of the present invention. In the second embodiment, a sending connector and a sending jack (4 in the first embodiment) are connected to a wiring board 2 of a LAN wiring unit. Terminal jack) is not provided. Instead, an L is connected to the unit-side connection end of the sending home wiring 6b connecting each LAN outlet and the LAN wiring unit.
A plug 18 having the same structure as the connection plug 13 of the AN drop-in line is connected. The structure of the second embodiment does not require a patch cord.

Although the same applies to the first embodiment, the connection plug 13 of the LAN service line for each dwelling unit is
If only BASE-T needs to be supported, an eight-terminal plug is not necessarily required, and a plug having four or more terminals may be used. Therefore, the LAN connection port of the wiring unit only needs to be a jack of four or more terminals corresponding to the plug. However, in consideration of future expandability, it is preferable to connect an eight-terminal plug and a jack.

The other parts of the second embodiment are configured in the same manner as the first embodiment. When only one terminal is used in the house, the LAN service line 3 may be connected to the eight-terminal jack 8 of the wiring board corresponding to the LAN outlet 5 to which the terminal is connected. When two terminals are used, the terminal 17 is connected to the outlet connected to the LAN connection cable 3 via the hub 16, and the cascade port of the hub is connected to the sending port 7 b of the outlet, which corresponds to this. The plug 18 connected to the end of the sending-side cable 6b may be connected to the eight-terminal jack 8 corresponding to the outlet to which the second terminal is to be connected. Similarly, the third and subsequent terminals can be connected by additionally providing a hub at a location where the terminal on the upstream side is installed.
