Problems solved by technology
Therefore, it is difficult to add new functions to the multimedia socket board or replace some functions of the existing multimedia socket board with other functions after the construction of the construction project is completed.
Also, repair work is required when exchanging existing multimedia socket boards for other multimedia boards
However, it is not easy for ordinary users to perform such maintenance work, and the cost of the maintenance work becomes a burden on the user
[0004] Therefore, from the point of view of easy interchangeability and functional expansion, the traditional multimedia socket board still has a lot of room for improvement

A dual wiring system with easy exchangeability of a function unit is provided. A gate device 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. The function unit has at least one of functions for supplying electric power from the electric power line, outputting information from the informationline and inputting information into the information line when connected with the gate device. The function unit has a module connector comprised of an electric power connector and an information signal connector, which is detachably connected to a module port of the gate device comprised of an electric power port and an information signal port. To further improve function expandability, an additional function unit can be detachably connected to the function unit.
Description
technical field [0001] The present invention relates to a dual wiring system that can be used to supply power and input and output information through power lines and signal lines installed in a structure. Background technique [0002] Due to the spread of the Internet, it is required to ensure that information networks can be accessed at many locations in building structures such as general residences and office buildings. For example, Japanese Patent Laid-Open No. 11-187154 discloses a multimedia wiring system including: a power distribution board for controlling power lines and various signal lines installed in a structure in a centralized control manner; and a multimedia outlet board , installed in the indoor wall surface, and connected to the distribution board through power lines and signal lines. For example, the multimedia outlet board includes power outlets for supplying commercial power to electrical appliances, outlets for receiving broadcast programs such as ter...
