[Problems to be Solved by Invention]

In the case where the operating device is to be embedded as a wiring device in an embedment hole provided in a construction surface such as a wall surface of a building, the size of the operating device has to be reduced. In order to miniaturize the operating device, a single-polarized antenna (inverted-F antenna) that is easy to miniaturize is used for the antenna. However, if the ground element does not have a size equal to or greater than half a wavelength, high-frequency current distribution will also occur in the power supply wiring. If an operating device having such an inverted-F antenna is constructed, a high-frequency current may even flow over the power supply circuit and be radiated to the power supply wiring. For this reason, the radiated electric field from the antenna is combined with the radiated electric field from the power supply wiring, and the directivity of the antenna becomes a deformed shape.

The present invention has been developed in view of such a situation, and an object thereof is to provide a technique that can make the directivity of the antenna approach omnidirectional even if the operating device is miniaturized. [Technical means to solve problems]

In order to solve the above-mentioned problems, an operation device according to an aspect of the present invention is an operation device having a first surface and a second surface facing opposite sides of each other, the operation device including: an operation part arranged on the first surface side; a power supply The part is arranged on the second surface side and is connected to the power supply wiring; and the control board is arranged between the operation part and the power supply part and spreads along at least one of the first surface and the second surface. The operation part accepts the operation; the power supply part supplies power from the power source to the load through the power supply wiring according to the operation accepted by the operation part; on one surface of the control board, a folded dipole antenna that can be used for wireless communication is arranged.

Another aspect of the present invention is a wiring device. This wiring device is fixed to the installation surface; the wiring device includes: an operation part for accepting user's operation; a first antenna constituting a folded dipole antenna for use in a first frequency band; and a second antenna for use in a higher frequency band than the first Band 2 of the frequency band. [Effect of invention]

According to the present invention, even if the operating device is miniaturized, the directivity of the antenna can be made close to omnidirectional.

Before describing the embodiment of the present invention in detail, the outline of the embodiment will be described first. The embodiment relates to a wiring system including a two-wire operating device for controlling a load. An example of the load is a lighting load, and the user can switch the lighting load on and off, or control the dimming of the lighting load by operating the operation part of the operation device. In order to present the lighting situation by controlling a plurality of lighting loads together, the operating device needs to be linked with other operating devices. In order to realize interlocking among plural operating devices, each operating device is equipped with a wireless communication function. Furthermore, if the operating device is equipped with a wireless communication function, the operating device can also be connected to the Internet via a gateway (GateWay) device to perform remote operations or obtain other services.

As described above, in order to reduce the size of the operating device, when an inverted-F antenna is used for the operating device, the radiated electric field from the antenna is combined with the radiated electric field from the power supply wiring, and the directivity of the antenna becomes a deformed shape. . If the directivity of the antenna becomes a deformed shape, there will be a direction in which the wireless communication distance is shortened. In the case of forming a local area network between a plurality of operating devices, the directivity of the antenna is preferably close to omnidirectional. In order to cope with this, the operating device of this embodiment includes a folded dipole antenna for wireless communication. Since the high-frequency current is enclosed in the loop when the dipole antenna is folded, the influence of the power wiring on the directivity is reduced. In the following description, "parallel" and "perpendicular" do not only refer to perfect parallelism and perpendicularity, but also include deviations from parallelism and perpendicularity within an error range. Again, "substantially" means about the same within that range.

FIG. 1 shows the structure of a wiring system 1000 . The wiring system 1000 includes: a first power line 10a and a second power line 10b collectively referred to as a power line 10 ; a first power source wire 20a , a second power source wire 20b , and a third power source wire 20c collectively referred to as a power source wire 20 ; and a lighting load 30 collectively The first lighting load 30a, the second lighting load 30b; the terminal device 50; Here, the number of combinations of the lighting load 30 and the operation device 100 is set to "2", but it is not limited to this. The number of terminal apparatuses 50 is set to "1", but is not limited to this.

The power line 10 is connected to, for example, a single-phase 100 [V], 50 or 60 [Hz] AC power source (not shown) to transmit AC power. The AC power source can be the city power provided by the power company and other power providers, but it can also be the self-use power generation equipment such as solar power generation equipment. The first power line 10a and the operating device 100 are connected by a first power supply wiring 20a, the operating device 100 and the lighting load 30 are connected by a second power supply wiring 20b, and the lighting load 30 and the second power line 10b are connected by a third power supply wiring 20c. That is, the operation device 100 and the lighting load 30 are connected one-to-one, and these combinations are extended and connected to the power line 10 through the first power supply wiring 20a to the third power supply wiring 20c. Here, the combination of the first operating device 100a and the first lighting load 30a and the combination of the second operating device 100b and the second lighting load 30b are connected to the power line 10 in the same manner.

The operation device 100 is, for example, a wiring device. The operation device 100 is fixed to the installation surface in a state in which the rear side portion is embedded in the embedding hole provided in the installation surface of the wall or the like. The operation device 100 is not limited to the embedded type structure, and the structure may be an exposed type directly attached to the installation surface, or a structure that can be used in any place without being fixed to a fixed position. The two-wire operating device 100 is electrically connected to the AC power supply in series with the lighting load 30 . The user operates the operation device 100 in order to turn on, turn off, and adjust the lighting load 30 . The operating device 100 has a load control function, and controls the current flowing to the lighting load 30 in response to an operation from a user, so that the lighting load 30 is turned on (full lighting or dimmed lighting) or turned off. The lighting load 30 turns on when power is supplied. The lighting load 30 includes, for example, a light source such as an LED (Light Emitting Diode), and a lighting circuit for lighting the light source.

Each operating device 100 has a wireless communication function constituted by, for example, a low-power wireless (specified low-power wireless) using radio waves in a 920 MHz band or a 420 MHz band. Here, as an example, it is assumed that it has a wireless communication function based on a specific low-power wireless radio in the 920 MHz frequency band. The operating devices 100 can communicate with each other wirelessly with a specific low power. In FIG. 1 , a specific low-power wireless is designated as the first wireless communication 60 .

When the first operation device 100a accepts the operation from the user, the first operation device 100a controls the lighting of the first lighting load 30a in accordance with the operation. Furthermore, the first operation device 100a transmits a wireless signal showing the operation content to the second operation device 100b through the first wireless communication 60 . The second operation device 100b controls the lighting of the second lighting load 30b according to the operation content presented by the received wireless signal. As a result, when the user operates the first operation device 100a, the first lighting load 30a and the second lighting load 30b are turned on in the same manner. The first operating device 100a can also send wireless signals to operating devices 100 other than the second operating device 100b, and the second operating device 100b can also forward the wireless signals received from the first operating device 100a to another operating device. 100. Thereby, three or more lighting loads 30 are turned on in the same manner.

Each operating device 100 also has a wireless communication function based on a communication standard for short-range wireless communication such as BLE (Bluetooth Low Energy (registered trademark)), for example. Furthermore, the terminal device 50 is, for example, a smartphone, a tablet terminal device, or a personal computer, and can perform short-range wireless communication such as BLE. Therefore, the operation device 100 and the terminal device 50 can communicate by short-range wireless communication. In FIG. 1 , the short-range wireless communication is designated as the second wireless communication 62 .

When the user operates the application program executed on the terminal device 50, the terminal device 50 transmits a wireless signal showing the operation content of the first lighting load 30a to the first operation device 100a through the second wireless communication 62. The first operating device 100a controls the lighting of the first lighting load 30a according to the operation content presented by the received wireless signal. Since the frequency band (hereinafter referred to as the "first frequency band") used for specific low-power wireless is the 920MHz frequency band, and the frequency band used in BLE (hereinafter referred to as the "second frequency band") is the 2.4 GHz frequency band, the second frequency band is high in Band 1.

FIG. 2 is a perspective view showing the appearance of the operating device 100 . As shown in FIG. 2 , an orthogonal coordinate system composed of the x-axis, the y-axis, and the z-axis is determined. The x-axis and the y-axis are orthogonal to each other. The z-axis is perpendicular to the x-axis and the y-axis, and extends in the height direction of the operating device 100 . Furthermore, the positive directions of the x-axis, the y-axis, and the z-axis are defined as the directions of the arrows in FIG. 2 , and the negative directions are defined as the opposite directions to the arrows. The positive direction of the z-axis is sometimes referred to as "upper" and "upper side", and the negative direction of the z-axis is referred to as "downward" and "lower side". Sometimes the positive direction of the x-axis is referred to as "front" and "front", and the negative direction of the x-axis is referred to as "rear" and "rear". Sometimes the positive direction of the y-axis is called "right" and "right", and the negative direction of the y-axis is called "left" and "left". Therefore, the z-axis is an axis extending in the vertical direction, the x-axis is an axis extending in the front-rear direction, and the y-axis is an axis extending in the left-right direction.

A box-shaped casing is formed by combining the plate body 200 arranged on the front side and the component box 210 arranged on the rear side in the front-rear direction. A rectangular first surface 110 is disposed on the front side of the plate body 200 , and a rectangular opening 202 is provided in the central portion of the first surface 110 .

In the component box 210, a switch frame 300 is installed from the rear side. The switch frame 300 is used to embed the operation device 100 in an embedment hole provided in an installation surface such as a wall. The switch frame 300 is a fixed installation frame fixed on the installation surface. The switch frame 300 is formed of metal, for example. On the switch frame 300, the body 400 is installed from the rear side. The body 400 has a box shape, and the rectangular second surface 120 is arranged on the rear side of the body 400 .

Therefore, the power supply unit is arranged on the second surface 120 side. In addition, the first surface 110 and the second surface 120 face each other on the opposite side.

FIG. 3 is an exploded perspective view showing the structure of the operation device 100 . The plate body 200 arranged on the frontmost side has the first surface 110 as described above, and the opening portion 202 is provided in the center portion of the first surface 110 . In the opening portion 202 , a panel-shaped touch panel 220 is arranged from the rear side, and a panel-shaped display panel 230 is arranged at the rear side of the touch panel 220 . The display panel 230 is, for example, an electronic paper or a liquid crystal display, and displays a screen for urging the user to operate. The so-called screen urging the user to perform an operation is a screen that presents an operation object such as a light-on button, a light-off button, or a dimming knob. Once the user operates an operation object such as a light-on button, a light-off button, or a dimming knob displayed on the display panel 230, the touchpad 220 will accept the operation performed by the user's finger. In the operation device 100, the display panel 230 may also be omitted.

On the rear side of the display panel 230, a plate-shaped control substrate 500 is arranged with a frame-shaped spacer (not shown) interposed therebetween. The control board 500 is also referred to as a first board. The spacer is formed of an insulating material such as resin. The touch panel 220 and the display panel 230 are fixed inside the casing formed by the combination of the panel 200 and the component box 210 through the spacer and the board 200 . The control substrate 500 is disposed between the touch panel 220 and the power supply unit (not shown), and extends along at least one of the first surface 110 and the second surface 120 at least. Furthermore, the front side of the control board 500 is the first surface 510 , and the rear side of the control board 500 is the second surface 512 . A control circuit (hereinafter referred to as a "display control circuit") for controlling the display on the display panel 230 is mounted on the control substrate 500 . The display control circuit is connected to the display panel 230 . Furthermore, the control board 500 is also mounted with a control circuit for controlling wireless communication (hereinafter referred to as a "control circuit for wireless communication") and an antenna. The configuration of the control board 500, especially the configuration of the antenna, will be described later. On the rear side of the control board 500, the component box 210 is arranged. In this way, the control board 500 and the like arranged between the board body 200 and the component box 210 are arranged inside the casing formed by the combination of the board body 200 and the component box 210 .

On the rear side of the component box 210, a switch frame 300 is arranged; on the rear side of the switch frame 300, a rear side cover (not shown) is arranged. The rear side cover seals the box-shaped body 400 with an opening on the front side from the front side. In the inner space of the body 400 formed by the combination of the rear cover and the body 400 , the relay substrate 420 , the insulating sheet 430 , and the power substrate 440 are sequentially arranged from the front side to the rear side. Furthermore, the rear side cover may not be provided, and the component box 210 may block the box-shaped body 400 with an opening on the front side from the front side. In this case, in the internal space of the body 400 formed by the combination of the component box 210 and the body 400 , the relay substrate 420 , the insulating sheet 430 , and the power supply substrate 440 are sequentially arranged from the front side to the rear side. The rear side cover and the body 400 are formed of insulating materials such as resin, and are formed of PBT (Polybutylene terephthalate; polybutylene terephthalate) resin or the like. The relay substrate 420 is mounted with a control circuit (hereinafter referred to as "operation control circuit") for controlling the operation in response to an operation received by the operation unit (touch panel 220 ). The operation control circuit is connected to the operation unit (touch panel 220 ) via the control board 500 and the like. The relay substrate 420 is also referred to as a second substrate, and the power substrate 440 is also referred to as a third substrate.

The power supply board 440 corresponds to the power supply unit described above, and is connected to the first power supply wiring 20a and the second power supply wiring 20b shown in FIG. 2 . The power supply board 440 is mounted with: a power supply circuit that converts the voltage of 100V from the AC power received from the power supply wiring 20 to a voltage of 5V used in the operation device 100; Dimming of the lighting load 30 . That is to say, the power supply board 440 will perform power supply to the lighting load 30 from the AC power supply via the power supply wiring 20 in response to the operation received by the touch panel 220 . On the rear side of the power supply board 440 , connection terminals connected to the power supply wiring 20 are provided. The connection terminals are arranged in the inner space of the body. The connection terminals can also be soldered to the rear side of the power supply substrate 440 . The connection terminal is formed of metal, for example. The insulating sheet 430 is arranged so that at least a part of the insulating sheet 430 overlaps with the connection terminal when viewed in plan from the X-axis direction. The power supply circuit includes, for example, a plurality of electronic components constituting an AC/DC converter that converts AC power supplied from an external AC power source via a connection terminal into DC power of a predetermined voltage. A plurality of electronic components, such as transformers, capacitors or resistors, etc. Transformers, capacitors, resistors, etc. are, for example, welded to the rear side of the power supply substrate 440 . In this case, it is possible to suppress the influence on the antenna, the control circuit for display, the control circuit for wireless communication, the control circuit for operation, etc. caused by the heat or electromagnetic field generated by electronic components such as transformers, capacitors, and resistors.

Hereinafter, the antenna provided on the control board 500 will be described, but as a premise, in order to clarify the problem with respect to the antenna, the control board 600 which is a comparison object of the control board 500 will be described first. The control board 600 is, for example, disposed on the operation device 100 in place of the control board 500 . FIGS. 4( a ) to ( c ) illustrate the structure of the control substrate 600 of the comparison object and the directivity formed by the inverted-F antenna 630 . FIG. 4( a ) shows the structure of the control board 600 ; the first surface 610 and the second surface 612 of the control board 600 correspond to the first surface 510 and the second surface 512 of the control board 500 . On the second surface 612, the ground element 620 and the inverted-F antenna 630 are mounted. The inverted-F antenna 630 is used as a specific low-power wireless antenna using the first frequency band. Since the ground element 620 and the inverted-F antenna 630 are well-known technologies, the description is omitted here.

FIG. 4(b) presents the directivity of the inverted-F antenna 630 alone. As shown in the figure, the individual directivity of the inverted-F antenna 630 is close to omnidirectional. FIG. 4( c ) shows the directivity of the inverted-F antenna 630 including the power wiring 20 . In order to reduce the size of the operating device 100, the size of the first surface 610 is limited. Furthermore, the size of the inverted-F antenna 630 depends on the frequency band used, for example, the 920MHz frequency band. Even in such a situation, the ground element 620 may not have a sufficient size. If the ground element 620 is not large enough, current distribution will occur in all the ground elements 620 due to the inverted-F antenna 630 . The high-frequency current generated in this way may even be dissipated and radiated to the power supply wiring 20 through the relay substrate 420 and the power supply substrate 440 . As a result, the radiated electric field from the inverted-F antenna 630 is combined with the radiated electric field from the power supply wiring 20, and as shown in FIG. 4(c), the radiated electric field becomes a deformed shape directivity.

In order to make the antenna directivity approach omnidirectional when the power wiring 20 is included, the antenna of this embodiment is shown in FIGS. 5( a ) to ( c ). FIGS. 5( a ) to ( c ) illustrate the structure of the control substrate 500 and the directivity formed by the folded dipole antenna 550 . FIG. 5( a ) shows the structure of the control board 500 ; on the second surface 512 of the control board 500 , a ground element 520 and a folded dipole antenna 550 are arranged. The folded dipole antenna 550 may be formed of metal or the like as a pattern on the printed substrate, or may be separately fabricated from metal or the like and then pasted.

The folded dipole antenna 550 is also referred to as a first antenna. The first antenna is, for example, a dipole antenna. The first antenna is an antenna for the first frequency band. The folded dipole antenna 550 is used as a specific low-power wireless antenna using the first frequency band. The element forming the loop shape of the folded dipole antenna 550 includes a first element 540 and a second element 542 that are different from each other. The first part 540 of the element extends from the first connecting point 530 to the first turning point 532 while bending, and then returns to the middle point 534 while bending from the first turning point 532 . The second portion 542 of the element extends from the intermediate point 534 to the second turning point 536 while bending, and then returns to the second connecting point 538 while bending from the second turning point 536 . Here, the first connection point 530 , the first turning point 532 , the intermediate point 534 , the second turning point 536 , and the second connecting point 538 are arranged near the center of the second surface 512 in the left-right direction. Furthermore, the length from the first connection point 530 to the first turning point 532, the length from the first turning point 532 to the middle point 534, the length from the middle point 534 to the second turning point 536, the length from the second turning point 532 The length from the turning point 536 to the second connection point 538 is approximately 1/4 wavelength.

Figure 5(b) presents the directivity of the folded dipole antenna 550 alone. As shown in the figure, the directivity of the folded dipole antenna 550 is close to omnidirectional. FIG. 5( c ) presents the directivity of the folded dipole antenna 550 including the power wiring 20 . The directivity shown in Fig. 5(c) is closer to the omnidirectionality than the directivity shown in Fig. 4(c). This is because when the dipole antenna 550 is folded, the high-frequency current is enclosed in the dipole antenna, so the influence of the power supply wiring 20 on the directivity is reduced. The folded dipole antenna 550 of FIG. 5( a ) is mounted on the second surface 512 facing the second surface 120 side in the control board 500 . This is to reduce the influence of fingers operating the touchpad 220 .

FIG. 6 shows another configuration of the control substrate 500 . The second surface 512 of the control board 500 includes a first side 514 extending in the left-right direction and a second side 516 extending in the vertical direction. The second side 516 is longer than the first side 514 . On the second surface 512 as described above, the ground element 520 and the folded dipole antenna 550 are arranged. The ground element 520 and the folded dipole antenna 550 may also be arranged on the first surface 510 of the control board 500 . The first part 540 of the element extends from the first connecting point 530 to the first turning point 532 while bending, and then returns to the middle point 534 while bending from the first turning point 532 . In particular, in the element first portion 540 , the portion arranged along the first side 514 without being bent should be longer than the portion arranged along the second side 516 without being bent. At least a part of the first part 540 of the device is arranged along the first side 514 of the control board 500 . At least a part of the first part of the device is arranged along the second side 516 of the control board 500 . At least a part of the first part 540 of the element is arranged along the fourth side facing the second side of the control board 500 .

On the other hand, the second part 542 of the element extends from the intermediate point 534 to the second turning point 536 while bending, and then returns to the second connecting point 538 while bending from the second turning point 536 . In particular, in the element second portion 542, the portion arranged along the second side 516 without being bent is made longer than the portion arranged along the first side 514 without being bent. That is, the first element portion 540 is mainly arranged along the first side 514 , and the second element portion 542 is mainly arranged along the second side 516 . The same applies to the length from the first connection point 530 to the first turning point 532 , the length from the first turning point 532 to the intermediate point 534 , the length from the intermediate point 534 to the second turning point 536 , and the The length from the second turning point 536 to the second connecting point 538 is approximately 1/4 wavelength. At least a part of the second part 542 of the device is arranged along the second side 516 of the control board 500 . At least a part of the second part 542 of the device is arranged along the third side facing the first side 514 of the control board 500 . The length of the second part 542 of the element along the second side 516 is greater than the length of the first part 540 of the element along the fourth side. The length of the first part 540 of the element along the first side 514 is greater than the length of the second part 542 of the element along the third side.

On the second surface 512, a control circuit for wireless communication (hereinafter referred to as "the first control circuit 570 for wireless communication") is arranged for performing wireless communication using the folded dipole antenna 550. The first wireless communication control circuit 570 has a communication function performed by a specific low-power wireless, and performs the first wireless communication 60 with other operating devices 100 . Furthermore, the first wireless communication control circuit 570 may be arranged on the first surface 510 . When the foldable dipole antenna 550 and the first control circuit 570 for wireless communication are arranged on different surfaces of the control board, the first control circuit 570 for wireless communication is connected to the foldable via a through hole provided in the control board 500 Dipole antenna 550.

The inverted-F antenna 560 is also called a second antenna. The second antenna is, for example, a monopole antenna. The second antenna is an antenna for the second frequency band. The inverted-F antenna 560 may be arranged on the second surface 512 of the control board 500 or may be arranged on the first surface 510 . A notch area 522 is provided in a part of the ground element 520 , and the inverted-F antenna 560 is mounted on the notch area 522 . The inverted-F antenna 560 is used as an antenna using BLE of the second frequency band. Since the second frequency band is higher than the first frequency band, the inverted-F antenna 560 is smaller than the folded dipole antenna 550 . Therefore, the size of the ground element 520 is sufficient for the inverted-F antenna 560 , so the directivity of the inverted-F antenna 560 is not easily affected by the power supply wiring 20 . On the first surface 510, a control circuit for wireless communication (hereinafter referred to as "the second control circuit 572 for wireless communication") for performing wireless communication using the inverted-F antenna 560 is arranged. When the inverted-F antenna 560 and the second wireless communication control circuit 572 are disposed on different surfaces of the control board, the second wireless communication control circuit 572 passes through a through hole (not shown in the figure) provided in the control board 500 ) is connected to the inverted-F antenna 560. The second wireless communication control circuit 572 has a communication function using BLE to execute the second wireless communication 62 with the terminal device 50 . Furthermore, the second wireless communication control circuit 572 may be arranged on the second surface 512 .
