As shown in FIG. 4, the configuration in which the extended function modules 9 and 90 can be added on the right side of the basic function module 8 has been described. However, the extended function module 9 can be added on the left side of the basic function module 8. The configuration can also be realized by replacing the rectifier circuit 28 and the DC / AC converter 29. A DC power supply unit 22 is connected to a line connecting the rectifier circuit 28 and the DC / AC converter 29 so as to obtain an operating power supply + V of the internal circuit.

It is preferable to appropriately adopt a routing protocol corresponding to unicast or broadcast capable of one-to-one or one-to-N correspondence. Further, the protocol used between the gate devices 3 and the protocol used in the function modules 8 and 9 connected to the gate device 3 may be made different. For example, protocol conversion may be performed on the gate device 3.

  In using the basic function module 8 constituting the functional device, first, the gate device 3 is first attached to the switch box 2 embedded in the appropriate wall surface of the building in advance through a mounting frame, and the power line L1 previously wired.

Thereafter, the corresponding connected portion of the connector 7 of the basic function module 8 is connected to the electric line connection port 6 provided on the front surface portion of the gate device 3, and the basic function module 8 is connected to the front surface portion of the gate device 3. Attach to the mounting frame to cover. When the basic function module 8 is attached, the front surface portion protrudes from the wall surface, and both side surfaces are exposed to the indoor side.

  The extended function modules 9 and 90 have one side surface (connection surface) in contact with one of the exposed side surfaces (connection surface) of the basic function module 8, and in this state, the extended function modules 9 and 90 are connected to The basic function module 8 is mechanically connected. As a result, the basic function module 8 and the extended function modules 9 and 90 constitute a functional device. At this time, as will be described later, as a fitting means for positioning, a fitting convex portion and a fitting concave portion are provided at corresponding positions on the connection surfaces of the respective modules, thereby ensuring the connection between the modules.

In this way, as shown in FIG. 2, the extended function modules 9 (9 ₁ ... 9 ₃ ) can be sequentially connected to the sides. When the 1/2 extended function module 90 is connected, two 1/2 extended function modules 90 (90 ₁ and 90 ₂ ) can be connected in the vertical direction. When only one ½ extended function module 90 is used and another extended function module 9 is connected to the ½ extended function module 90, it is configured in the same size as the ½ extended function module 90 so that only power transmission is possible. It is good also as connecting the 1/2 extended function module (it has only a non-contact electric power feeding mechanism).

  Since the basic function module 8 can connect the extended function modules 9 and 90 to both sides, the extended function modules 9 and 90 may be connected to both sides of the basic function module 8. After connecting the extended function modules 9 and 90 in this way, the end cover is detachably attached to the side portions of the extended function modules 9 and 90 located at both ends or the anti-connection portion of the basic function module 8. Thus, the connection construction of the extended function modules 9 and 90 is completed. In addition, when the extended function modules 9 and 90 are not connected to the basic function module 8, that is, when they are left unused, end covers are attached to both sides of the basic function module 8.

When the extended function module 9 having the E-type core 18 is further connected to the two 1/2 extended function modules 90 ₁ and 90 ₂ arranged in parallel, the two extended function modules 9 having the E-type core 18 have two Electric power can be received from each of the U-shaped cores 180 ₁ and 180 ₂ of the 1/2 extended function modules 90 ₁ and 90 ₂ . Therefore, even when power is distributed to the two 1/2 extended function modules 90 ₁ and 90 _{2 on the way} , power can be efficiently supplied to the extended function modules 9 and 90 ahead. Therefore, it is possible to deal with various variations of the housing.

Here, the 1/2 extended function module 90 will be described in more detail. FIG. 5 is a circuit configuration diagram of the 1/2 extended function module in the present embodiment. FIG. 5 shows a state in which two 1/2 extended function modules 90 ₁ and 90 ₂ of this embodiment are arranged vertically (vertical direction). The 1/2 extended function modules 90 ₁ and 90 ₂ of this embodiment have U-shaped cores 180 ₁ and 180 ₂ , and when the two extended function modules 90 ₁ and 90 ₂ are connected side by side, the 1/2 extended function modules 90 ₁ and 90 ₂ are connected to each other.

Further, at the upper end and lower end of the 1/2 extended function modules 90 ₁ , 90 ₂ , connectors 24 ₁ , 24 ₁ as communication units that can be electrically connected to the oscillation circuits 23 ₁ , 23 ₂ (and thus capable of signal communication). 24 ₂ (upper end side), 25 ₁ , 25 ₂ (lower end side).

In the extended function modules 90 ₁ and 90 ₂ , two sets of electromagnetic coupling portions including the U-shaped cores 180 ₁ and 180 ₂ and the coils 190 ₁ and 190 ₂ described above are provided, and the interior (side) close to both side walls of the module body. Arranged at both ends). Rectifier circuits 28 ₁ and 28 ₂ are electrically connected to one electromagnetic coupling unit (secondary side) serving as a power receiving unit, and the electric power received from the primary side of the basic function module 8 or the other extended function module 9 Is smoothed.

In addition, switching circuits 30 ₁ and 30 ₂ electrically connected to the rectifier circuits 28 ₁ and 28 ₂ are electrically connected and smoothed to the other electromagnetic coupling unit (primary side) serving as a power supply unit. Power is converted into AC power with a high frequency. The switching circuits 30 ₁ and 30 ₂ are electrically connected to the oscillation circuits 23 ₁ and 23 _{2. When the} 1/2 extended function modules 90 ₁ and 90 ₂ are connected side by side, the oscillation circuits 23 ₁ and 23 _{2 are connected.} The power supplied in each power supply unit is synchronized based on the reference signal from. The side surface position of the module body where the tips of the magnetic cores 190 ₁ and 190 ₂ constituting these electromagnetic coupling portions are arranged close to each other is the magnetic coupling portion. DC power supply sections 22 ₁ and 22 ₂ are connected to the lines connecting the rectifier circuits 28 ₁ and 28 ₂ and the DC / AC converters 29 ₁ and 29 ₂ to obtain an operating power supply + V of the internal circuit. Yes. In addition, the configuration of the functional unit and the like is the same as that of the extended function module 9 of FIG.

In this embodiment, when the basic function module 8 or the extended function module 90 having the E-type core 18 is connected, the extended function module 90 having the U-type core 180 on the upper end side or the lower end side can be connected. In Figure 5, the extended functional module 90 ₁ is the upper, extended functional module 90 ₂ is arranged such that the lower side. In this case, extension module 90 ₁ of the connector 25 ₁ of the lower end and the connector 24 and _second extension modules 90 ₂ of the upper end portion is electrically connected. That is, the extended functional module 90 ₁ of the connector 25 ₁ of the lower end and the connector 24 and _second extension modules 90 ₂ of the upper end portion is the signal can communicate. As a result, synchronization can be achieved by using _one of the oscillation circuits 23 ₁ and 23 ₂ of the extended function modules 90 ₁ and 90 ₂ .

In FIG. 5, the changeover switch 31 _1, 31 ₂ are switched to a state of using the oscillation circuit 23 ₁ of the extension module 90 _1. When one of these change-over switches 31 ₁ and 31 ₂ is switched, one of the other switches automatically in the opposite direction (if one uses its own oscillation circuit, the other does not use its own oscillation circuit). It is preferable to switch automatically.

In this way, the power supplied to the respective switching circuits 30 ₁ and 30 ₂ is synchronized with each other based on the reference signal oscillated from either one of the oscillation circuits 23 ₁ and converted into AC power having a high frequency. In this way, it is possible to easily synchronize the extended function modules 90 having the U-shaped core 180 when they are arranged in parallel. The converted AC power can be supplied to the further connected extension function modules 9 and 90 via the cores 180 ₁ and 180 ₂ around which the coils 190 ₁ and 190 _{2 serving as} power supply units are wound. In particular, when the extended function module 9 having the E-type core 18 is further connected, the two U-type cores 180 ₁ and 180 ₂ are in a synchronized state (a state approximated when the E-type core is adopted as the primary side). Therefore, power can be supplied more efficiently.

In the present embodiment, an example in which the connectors 24 ₁ , 24 ₂ , 25 ₁ , 25 ₂ are electrically connected to the oscillation circuits 23 ₁ , 23 ₂ is shown, but the present invention is not limited to this. It can be realized by a communication unit configured to be capable of signal communication such as optical communication and magnetic communication.

  Next, another example of the 1/2 extended function module will be described. FIG. 6 is a circuit configuration diagram showing another example of the 1/2 extended function module of the present embodiment. The circuit configuration of the present example is different from the circuit configuration in FIG. 5 in that the oscillation circuit 23 or other extension included in the extension function module 90 of its own depends on which connector 24 or 25 is connected to the extension function module 90. The function module 90 is configured to have a switching mechanism for switching to use one of the oscillation circuits 23 included in the functional module 90.

In this example, the connector 25 on the lower end side is electrically connected to the DC power supply unit 22 in addition to the oscillation circuit 23. In addition, when the connector 25 on the lower end side of the other 1/2 extended function module 90 is connected to the connector 24 on the upper end side, a switch 26 that is a switching mechanism that senses energization from the DC power supply unit 22. 27. The first switch 26 is turned on when the connector 25 on the lower end side of the other 1/2 extended function module 90 is connected to the connector 24 on the upper end side, and the oscillation of the other 1/2 extended function module 90 is performed. The circuit 23 is electrically connected to its own switching circuit 30. On the other hand, the second switch 27 is connected to the first switch 26 via the NOT circuit 30 so that the connector 25 on the lower end side of the other 1/2 extended function module 90 is connected to the connector 24 on the upper end side. When connected, it is turned off, and the electrical connection between its own oscillation circuit 23 and its own switching circuit 30 is released. When the connection is released (when power is not supplied), the first switch 26 is turned off and the second switch 27 is turned on. In FIG. 6, since the connector 25 ₁ on the lower end side of the upper half extended function module 90 ₁ and the connector 24 ₂ on the upper end side of the lower half extended function module 90 ₂ are connected, In the lower 1/2 extended function module 90 ₂ , the first switch 26 ₂ is turned on, and the reference signal from the oscillation circuit 23 _{1 of} the upper 1/2 extended function module 90 ₁ is sent to the lower (self) In addition to being introduced into the switching circuit 30 ₂ of the 1/2 extended function module 90 ₂ , the second switch 27 ₂ is turned off and the connection with the own oscillation circuit 23 ₂ is cut off. On the other hand, since the connector 24 ₁ on the upper end side of the upper half extended function module 90 ₁ is not connected, the first switch 26 ₁ is turned off, while the second switch 27 ₁ is turned on and its own oscillation circuit is turned on. The connection between 23 ₁ and the switching circuit 30 ₁ is maintained.

Thus, when two 1/2 extended function modules 90 are arranged, the oscillation circuit 23 _{1 of the} 1/2 extended function module 90 ₁ that is always on the upper side is electrically connected to the switching circuits 30 ₁ and 30 _2. Thus, at the same time, the oscillator circuit 23 ₂ of the lower half extended function module 90 ₂ can be omitted. In this embodiment, the upper oscillation circuit 23 ₁ is always used. However, the lower oscillation circuit 23 ₂ may be used, and the above-described changeover switch may be used together. It is good.

  As described above, when the extended function module 90 having the U-shaped core 180 is connected in parallel, depending on which of the connectors 24 and 25 on the upper end side or the lower end side is connected by the switching mechanism, The use of the oscillation circuit 23 included in the extended function module 90 is alternatively switched. Then, synchronization is taken using the oscillation circuit 23 included in one of the switched extended function modules 90. As described above, it is determined in advance that the oscillation circuit 23 of the extended function module 90 that is on the upper side or the lower side when connected in parallel and the side to which the connectors 24 and 25 are connected is detected. Whether to use the oscillation circuit 23 of the extended function module 90 is automatically switched. Therefore, the selection of the oscillation circuit 23 that is a reference for synchronization in the extended function modules 90 can be automatically switched.

  Although the embodiment according to the present invention has been described above, the present invention is not limited to the above embodiment, and various improvements, changes, and modifications can be made without departing from the spirit of the present invention.
