  The function modules 8 and 9 used in the present wiring system have the above-described configuration. When these function modules 8 and 9 are used, first, a switch box that is embedded in advance on a wall surface at a proper place in the building. 2, the power line L1 and the information line L2 are drawn out and the power line L1 and the information line L2 are attached to the gate device 3, and then the gate device 3 is attached to the switch box 2 via the attachment frame 4. And after inserting the plug blades 44 and 45 provided on the back surface of the basic function module 8 into one end side (the end portion in the counterclockwise direction) of the plug blade insertion ports 40 and 41 provided on the front surface portion of the gate device 3, When the module main body 8A of the basic function module 8 is rotated clockwise and the plug blades 44 and 45 are moved to the other end side of the plug blade insertion ports 40 and 41, the plug blades 44 and 45 are connected to the gate device 3.

In this attached state, the basic function module 8 protrudes from the front surface than the wall surface, and both side surfaces are exposed to the indoor side. Here, in this wiring system, when the power supply hooking blade 44 is inserted from one end side (wide portion 40a) of the plug blade insertion port 40 and moved to the other end side of the plug blade insertion port 40, the power supply hooking plug is obtained. Since the blade 44 is hooked and held by the power supply hook receiving member 42, it is possible to prevent the basic function module 8 from falling off the gate device 3. Moreover, when the power hook blade 44 is moved from the other end of the plug blade insertion port 40 to one end (the wide portion 40a), the holding state of the power hook blade 44 and the power hook receiving member 42 is released. Therefore, the basic function module 8 can be easily detached from the gate device 3.

When the extended function module 9 is not connected to the basic function module 8, the end cover 28 may be attached to both sides of the basic function module 8.

  In the basic function module 8 in which the extended function module 9 is connected as described above, the AC / AC converter 13 generates a low-voltage AC power source by reducing the commercial power source AC to a predetermined voltage and converting the frequency to a high frequency. The power is supplied to the adjacent extended function module 9 in a non-contact manner. Further, in the extended function module 9 that receives power supply from the basic function module 8, when another extended function module 9 is connected, power is further supplied by non-contact power supply by magnetic coupling through an internal circuit. In this way, a power path for supplying the low-voltage AC power supply in a non-contact manner from the basic function module 8 side to the extended function module 9 existing at the outermost end is constructed.
