Abstract

PURPOSE:To integrate an information wiring system with a power wiring system by miniaturizing a hub through the restriction of the number of ports so that the hub is suitable for underfloor installation. CONSTITUTION:A power wiring integrating hub 10 comprises an electric power input part 11, cascade connection part 12, and multi-port repeater part 13. Electric power is supplied through the electric power input part 11, which is connector-shaped to fit a joint box of an underfloor electric power wiring system. The hub is miniaturized by limiting the number of ports of the multi-port repeater part 13 so that it can be installed under the floor. Thus, a multi-port repeater for LAN complying with tone IEEE802.3 standard can be installed under the floor, and an information wiring system can be integrated with an underfloor power wiring system.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power wiring integrated HUB using a multi-port repeater conforming to the IEEE 802.3 standard, and an information wiring system used for LAN equipment conforming to the IEEE standard and intelligent buildings. And the power wiring system.

[0002]

2. Description of the Related Art Conventionally, LANs conforming to the IEEE standard have been widely used. FIG. 4 shows a usage example of the multi-port repeater 40 conforming to the IEEE802.3 standard. The multi-port repeater (HUB) 40 includes a backbone 42, which is a higher level network, and a cross-connect 4
1 through which the twisted pair cable 14 is connected as a medium to the outlets 15, and terminals can be connected to the respective outlets 15.

Normally, the multi-port repeater 40 is installed and used above the floor surface, has a function of connecting terminals of 8 ports or more, and is centrally managed at one place on the floor. However, it is rarely used to occupy one floor, and when one floor is divided and used, the method of centralized management at one place on the floor is inferior in flexibility and lacks expandability for users. There was a problem. Therefore, there is a problem that maintenance is difficult. In addition, the power of LAN devices including this multi-port repeater is supplied from an external power supply means such as a table tap or an outlet using an AC cord or an AC adapter. There is a problem in that a power cable such as an AC cord cannot be legally used under the floor for safety reasons. Therefore, when installing a LAN device under the floor, it is necessary to crawl the power cable over the floor, which is remarkably beautiful. There was a problem of damage.

On the other hand, FIG. 5 shows the configuration of a conventional power wiring system. In the joint boxes 20 dispersedly arranged on the floor, the distribution boards 30 to the power cables 3 are provided.
Power is supplied via 1. As shown in FIG. 6, this joint box 20 is composed of four ports, of which the two port connection parts 21 and 22 are for wiring for sequentially sending electric power, and the remaining two port connection parts 23. , 2
4 is for power branching. Since this joint box 20 is used under the floor, the joint box 20 is provided with a fitting portion from which the cable cannot be easily removed. The underfloor wiring system of this type and the information wiring system as shown in FIG. 4 are conventionally configured as separate systems, and there is no relation between the two systems.

SUMMARY OF THE INVENTION An object of the present invention is to limit the number of ports of a multi-port repeater to miniaturize it, so that a multi-port repeater of a LAN conforming to the IEEE802.3 standard can be stored under the floor. The information wiring system can be integrated with the underfloor power wiring system. Another object is to make network management easy and flexible layout change without impairing the aesthetics of the floor.

Power wiring integrated H of the present invention
In UB, in order to solve the above problems, IEEE
In a multi-port repeater complying with the E802.3 standard, a number suitable for storing under the floor the number of ports that were conventionally provided at 8 ports or more (1 port for cascade connection, 4 ports for terminal connection, for example, 5 ports). By restricting the number of ports, the size can be greatly reduced, and it can be stored under the floor so that power can be supplied from the power wiring system under the floor. In addition, the small-scale multi-port repeaters distributed in the floor improve the flexibility of the network and make it easy to expand, facilitating maintenance. In addition, an information wiring system and an underfloor power wiring system, which are arranged under the floor by providing connector means for the underfloor power wiring system for power supply, centering on a LAN multi-port repeater compliant with the IEEE802.3 standard, It is possible to connect.

[0007]

According to the present invention, the multiport repeater is installed under the floor and the power is supplied safely by incorporating the connector means of the underfloor power wiring system in the power input part of the multiport repeater complying with the IEEE802.3 standard. This makes it possible to integrate the information wiring system and the underfloor power wiring system to construct a power integrated information wiring system. Also, by disposing small multiport repeaters under the floor in a distributed manner, it is possible to quickly deal with layout changes and the like, and it is possible to facilitate maintenance.

FIG. 1 is a block diagram showing the basic construction of the present invention. The power wiring integrated HUB 10 of the present invention includes a power supply input unit 11, a cascade connection unit 12, and a multiport repeater unit 13. The power input unit 11 has a connector shape that fits with the joint box 20 of the underfloor power wiring system, and supplies power from here. The cascade connection unit 12 is an interface unit for connecting to the above network. The multiport repeater unit 13 has a multiport repeater function conforming to the IEEE802.3 standard, and connects a plurality of terminals via a twisted pair cable.

FIG. 2 shows a wiring system using the power wiring integrated HUB 10 of the present invention. The joint boxes 20 of the underfloor power wiring system, which are dispersedly arranged on the floor, are supplied with power from a distribution board 30 via a power cable 31. H to manage the entire floor
UB40 is backbone 4 which is a higher level network
2 and the cross connect 41. The power wiring integrated HUB of the present invention dispersedly arranged in the floor
10 is a HUB using a twisted pair cable 14 as a medium.
It is connected to 40. Each power wiring integrated HUB 10 operates by being supplied with power from the nearest joint box 20.
