[Background technology] 1. In recent years, a large number of computers have been introduced into offices and LAN systems have been constructed. A large number of conventional cables such as telephone lines are now being installed in offices, and so-called wiring flooding has become a problem. When such a large number of cables are placed on the floor, there is a risk of the cables being scratched, which poses a safety problem, so it is common practice to provide a pit and store the cables in the pit. However, if the location in the office is changed, it becomes necessary to change the location of the outlet to correspond to the location of the computer or telephone, and in this case, the pit may become useless.

For this reason, free access floors have come to be used in which floor panels are placed above the foundation floor via wiring spaces, and the entire wiring space is used as a path for cables. Such raised floors allow a lot of flexibility in the location of cables, but because supports are needed to support the floor panels on the foundation floor, the location of the electrical outlets can be completely different from the original location. When changing the location or adding more hooks, the support gets in the way and construction is troublesome. Moreover, the telephone line
Even if different types of cables, such as power lines and data signal lines, coexist, there is a risk of interference.
