Abstract

A dual wiring system with improved function expandability is provided. A base unit is mounted in a wall surface of a structure, and connected to both of an electric power line and an information line previously installed in the structure. Each of function units has at least one of functions for providing electric power from the electric power line, outputting information from the information line and inputting information into the information line when connected with the base unit. The base unit is detachably connected with one of the function units by use of a joining member, so that electric power is supplied from the base unit to the function unit through a power transmission means, and a signal transmission between the base unit and the function unit is obtained through a signal transmission means.

Claims

1. A dual wiring system comprising:

a base unit adapted in use to be mounted in a wall surface of a structure, and connected to both of an electric power line and an information line installed in said structure;

a function unit having at least one of functions for providing electric power from said electric power line, outputting information from said information line and inputting information into said information line, when connected with said base unit;

a power transmission means configured to supply the electric power from said base unit to said function unit;

a signal transmission means configured to make a signal transmission between said base unit and said function unit; and

a joining means configured to detachably connect said function unit to said base unit.

2. The dual wiring system as set forth in claim 1, wherein said power transmission means is configured to supply the electric power from said base unit to said function unit in a noncontact manner by means of electromagnetic coupling.

3. The dual wiring system as set forth in claim 1, wherein said signal transmission means is configured to make the signal transmission between said base unit and said function unit in a noncontact manner by means of optical coupling.

4. The dual wiring system as set forth in claim 1, wherein said base unit and said function unit has a pair of an electric power port and an electric power connector, which are detachably connected to each other to supply the electric power from said base unit to said function unit in a noncontact manner by means of electromagnetic coupling as said power transmission means, and a pair of an information signal port and an information signal connector, which are detachably connected to each other to make a signal transmission between said base unit and said function unit in a noncontact manner by means of optical coupling as said signal transmission means.

5. The dual wiring system as set forth in claim 1, wherein said base unit has a housing, which is formed with a rear portion embedded in said wall surface, front portion having at least one of an outlet configured to receive a power plug of an electric appliance, and a switch configured to turn on/off the electric appliance, and a side portion having said power transmission means and said signal transmission means to detachably connect said function unit to said base in a direction along said wall surface.

6. The dual wiring system as set forth in claim 1, wherein said base unit has a housing, which is formed with a rear portion having terminals to be connected to said electric power line and said information line, and a front portion having said power transmission means and said signal transmission means.

7. The dual wiring system as set forth in claim 1, wherein said base unit is formed with a main housing detachably connected to said function unit by use of said joining means, and a gate housing having terminals connectable to said electric power line and said information line, and wherein said gate housing and said main housing have a pair of a module port and a module connector, which are detachably connected to each other to simultaneously establish both of supplying the electric power from said gate housing to said main housing, and making a signal transmission between said gate housing and said main housing.

8. The dual wiring system as set forth in claim 1, wherein said joining means comprises engaging portions formed on each of said base unit and said function unit and a joining member configured to slidably contact the engaging portions and make the mechanical connection between said base unit and said function unit such that a region of said joining member is engaged to the engaging portion of said base unit and the remaining region of said joining member is engaged to the engaging portion of said function unit.
