The present disclosure relates to an operation technique, an operation device for receiving an operation, and a wiring device.

The operating device is arranged between the power supply and the load, and controls the power supply from the power supply to the lighting load according to the operation of the user.

Japanese Unexamined Patent Publication No. 2016-21315

When the operating device is embedded as a wiring device in an embedding hole provided in a construction surface such as a wall surface of a building, the operating device is required to be miniaturized. In order to reduce the size of the operating device, a monopole antenna (inverted F type antenna), which can be easily miniaturized, is used as the antenna. However, if the ground element does not have a size of half a wavelength or more, a high frequency current distribution also occurs in the power supply wiring. When an operating device equipped with such an inverted-F antenna is installed, a high-frequency current flows to the power supply wiring at the end of the power supply circuit and radiates. As a result, the radiated electric field from the antenna and the radiated electric field from the power supply wiring are combined, and the directivity of the antenna becomes distorted.

The present disclosure has been made in view of such circumstances, and an object of the present invention is to provide a technique for making the directivity of an antenna close to omnidirectional even if the operating device is miniaturized.

In order to solve the above problems, the operation device of a certain aspect of the present disclosure is an operation device having a first surface and a second surface facing each other, and the operation unit is arranged on the first surface side. , Arranged between the power supply unit arranged on the second surface side and connected to the power supply wiring, and the operation unit and the power supply unit, and spread along at least one of the first surface and the second surface. It is equipped with a control board. The operation unit receives the operation, the power supply unit executes power supply from the power supply to the load via the power supply wiring according to the operation received by the operation unit, and one side of the control board is folded back which can be used for wireless communication. A dipole antenna is placed.

Another aspect of the present disclosure is a wiring device. This wiring device is a wiring device fixed to the installation surface, and is higher than the operation unit that receives the user's operation, the first antenna for the first frequency band constituting the folded dipole antenna, and the first frequency band. It comprises a second antenna for the second frequency band.

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

It is a figure which shows the structure of the wiring system which concerns on Example. It is a perspective view which shows the appearance of the operation apparatus of FIG. It is an exploded perspective view which shows the structure of the operation apparatus of FIG. 4 (a)-(c) are diagrams showing the configuration of the control board to be compared and the directivity of the inverted F-shaped antenna. 5 (a)-(c) are diagrams showing the configuration of the control board of FIG. 3 and the directivity of the folded dipole antenna. It is a figure which shows another structure of the control board of FIG. 7 (a)-(b) are diagrams showing the directivity of the folded dipole antenna of FIG.

An outline of the present embodiment will be described before the embodiment of the present disclosure is specifically described. 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 when the user operates the operation unit of the operating device, the lighting load is switched on and off, and the dimming of the lighting load is controlled. In order to produce a lighting scene by collectively controlling a plurality of lighting loads, the operating device is required to be linked with other operating devices. In order to realize interlocking between a plurality of operating devices, each operating device is equipped with a wireless communication function. Further, when the operation device is equipped with a wireless communication function, the operation device can be connected to the Internet via a GW (Gateway) device, and remote control or other services are provided.

As mentioned above, when an inverted-F antenna is used for the operating device in order to reduce the size of the operating device, the radiated electric field from the antenna and the radiated electric field from the power supply wiring are combined, and the directivity of the antenna is distorted. It becomes. When the directivity of the antenna becomes a distorted shape, a direction in which the wireless communication possible distance becomes short appears. When forming a network between a plurality of operating devices, it is preferable that the directivity of the antenna is close to omnidirectional. In order to cope with this, the operating device according to the present embodiment includes a folded dipole antenna for wireless communication. In the folded dipole antenna, the high frequency current is confined in the loop, so that the influence of the power supply wiring on the directivity is reduced. In the following description, "parallel" and "vertical" include not only perfectly parallel and vertical, but also cases of deviation from parallel and vertical within the margin of error. In addition, "abbreviation" means that they are the same in an approximate range.

FIG. 1 shows the configuration of the 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 supply wiring 20a collectively referred to as a power supply wiring 20, a second power supply wiring 20b, a third power supply wiring 20c, and a lighting load 30. It includes a first lighting load 30a, a second lighting load 30b, a terminal device 50, a first operation device 100a, and a second operation device 100b, which are collectively referred to as an operation device 100. Here, the number of combinations of the lighting load 30 and the operating device 100 is set to "2", but is not limited thereto. The number of terminal devices 50 is set to "1", but is not limited thereto.

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 may be a commercial power source produced by an electric power company such as an electric power company, or may be a private power generation facility such as a solar power generation facility. The first power line 10a and the operation device 100 are connected by the first power supply wiring 20a, the operation device 100 and the lighting load 30 are connected by the second power supply wiring 20b, and the lighting load 30 and the second power line 10b are connected by the third power supply wiring 20c. Be connected. That is, the operating device 100 and the lighting load 30 are connected on a one-to-one basis, and these combinations are fed and wired to the power line 10 by 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 similarly connected to the power line 10.

The operating device 100 is, for example, a wiring device. The operating device 100 is fixed to the installation surface in a state where the rear portion is embedded in an embedding hole provided in the installation surface such as a wall. The operating device 100 is not limited to the embedded type structure, and may have an exposed type structure that is directly attached to the installation surface, or may have a structure that is not fixed in a fixed position and is used at an arbitrary place. .. The two-wire operating device 100 is electrically connected to the lighting load 30 in series with the AC power supply. The user operates the operating device 100 in order to turn on, turn off, and adjust the lighting load 30. The operation device 100 has a load control function for turning on (full lighting or dimming lighting) or turning off the lighting load 30 by controlling the current flowing through the lighting load 30 according to the operation received from the user. The lighting load 30 lights up when the power is turned on. 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, for example, a radio communication function by a low power radio (specified low power radio) that uses radio waves in the 920 MHz band or 420 MHz band. Here, as an example, it is assumed that a wireless communication function by a specific low power radio in the 920 MHz band is provided. The operating devices 100 can communicate with each other by the specified low power radio. In FIG. 1, the specific low power radio is shown as the first radio communication 60.

When the first operating device 100a receives an operation from the user, the first operating device 100a controls the lighting of the first lighting load 30a according to the operation. Further, the first operating device 100a transmits a radio signal indicating the operation content to the second operating device 100b by the first wireless communication 60. The second operating device 100b controls the lighting of the second lighting load 30b according to the operation content indicated by the received wireless signal. As a result, when the user operates the first operating device 100a, the first lighting load 30a and the second lighting load 30b are similarly turned on. The first operating device 100a may transmit a wireless signal to an operating device 100 other than the second operating device 100b, and the second operating device 100b may send the wireless signal received from the first operating device 100a to another operating device 100. It may be transferred to the operating device 100. As a result, three or more lighting loads 30 are similarly lit.

Each operating device 100 also has a wireless communication function compliant with a communication standard for short-range wireless communication such as BLE (Bluetooth (registered trademark) Low Energy). Further, the terminal device 50 is, for example, a smartphone, a tablet terminal device, or a personal computer, and can execute short-range wireless communication such as BLE. Therefore, the operation device 100 and the terminal device 50 can communicate with each other by short-range wireless communication. In FIG. 1, the short-range radio communication is shown as the second radio communication 62.

When the user operates the application executed in the terminal device 50, the terminal device 50 transmits a radio signal indicating the operation content of the first lighting load 30a to the first operating device 100a by the second wireless communication 62. .. The first operating device 100a controls the lighting of the first lighting load 30a according to the operation content indicated by the received wireless signal. The frequency band used in the specified low power radio (hereinafter referred to as "first frequency band") is the 920 MHz band, and the frequency band used in BLE (hereinafter referred to as "second frequency band") is the 2.4 GHz band. Therefore, the second frequency band is higher than the first frequency band.

FIG. 2 is a perspective view showing the appearance of the operating device 100. As shown in FIG. 2, an orthogonal coordinate system including an x-axis, a y-axis, and a z-axis is defined. The x-axis and 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. Further, the positive direction of each of the x-axis, the y-axis, and the z-axis is defined in the direction of the arrow in FIG. 2, and the negative direction is defined in the direction opposite to the arrow. The positive direction of the z-axis may be referred to as "upper" or "upper", and the negative direction of the z-axis may be referred to as "lower" or "lower". The positive direction of the x-axis may be referred to as "forward" and "front side", and the negative direction of the x-axis may be referred to as "rear" and "rear side". The positive direction of the y-axis may be referred to as "right" or "right", and the negative direction of the y-axis may be referred to as "left" or "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 housing is formed by combining the plate 200 arranged on the front side and the unit case 210 arranged on the rear side in the front-rear direction.

The switch frame 300 is attached to the unit case 210 from the rear side. The switch frame 300 is used for embedding and arranging the operation device 100 in an embedding hole provided in an installation surface such as a wall. The switch frame 300 is an installation fixing frame fixed to the installation surface. The switch frame 300 is made of metal, for example. The body 400 is attached to the switch frame 300 from the rear side. The body 400 has a box shape, and a 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. Further, the first surface 110 and the second surface 120 face opposite to each other.

FIG. 3 is an exploded perspective view showing the configuration of the operating device 100. As described above, the plate 200 arranged on the frontmost side has the first surface 110, and the opening 202 is provided in the central portion of the first surface 110.

The screen for prompting the user to operate is a screen showing an operation target such as a lighting button, an extinguishing button, and a dimming knob. When the user operates an operation target such as a lighting button, an extinguishing button, or a dimming knob displayed on the display panel 230, the touch panel 220 receives an operation by the user's finger. The display panel 230 may be omitted in the operating device 100.

On the rear side of the display panel 230, a plate-shaped control board 500 is arranged via a frame-shaped spacer (not shown). The control board 500 is also called a first board. The spacer is made of an insulating material such as resin. The touch panel 220 and the display panel 230 are fixed to the inside of the housing composed of the combination of the plate 200 and the unit case 210 by the spacer and the plate 200. The control board 500 is arranged 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. Further, the front surface of the control board 500 is the first surface 510, and the rear surface of the control board 500 is the second surface 512. The control board 500 is equipped with a control circuit (hereinafter, referred to as “display control circuit”) for controlling the display on the display panel 230. The display control circuit is connected to the display panel 230. Further, the control board 500 is also equipped with a control circuit for controlling wireless communication (hereinafter referred to as “wireless communication control circuit”) and an antenna. The configuration of the control board 500, particularly the configuration of the antenna, will be described later. A unit case 210 is arranged on the rear side of the control board 500. In this way, the control board 500 or the like arranged between the plate 200 and the unit case 210 is arranged inside the housing composed of the combination of the plate 200 and the unit case 210.

A switch frame 300 is arranged on the rear side of the unit case 210, and a rear cover (not shown) is arranged on the rear side of the switch frame 300. The rear cover seals the box-shaped body 400 whose front side is open from the front side. In the internal space of the body 400 formed by the combination of the rear cover and the body 400, the relay board 420, the insulating sheet 430, and the power supply board 440 are arranged in order from the front side to the rear side. Further, the unit case 210 may not have a rear cover and may seal the box-shaped body 400 having an open front side from the front side. In this case, the relay board 420, the insulating sheet 430, and the power supply board 440 are arranged in order from the front side to the rear side in the internal space of the body 400 formed by the combination of the unit case 210 and the body 400. The rear cover and the body 400 are formed of, for example, an insulating material such as a resin, and are formed of a PBT (Polybutylene terephthate) resin or the like. The relay board 420 is equipped with a control circuit (hereinafter referred to as "operation control circuit") for controlling the operation according to the 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 or the like. The relay board 420 is also referred to as a second board, and the power supply board 440 is also referred to as a third board.

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 in FIG. The power supply board 440 has a power supply circuit that executes conversion from the AC power voltage 100V received from the power supply wiring 20 to the voltage 5V used in the operation device 100, and a lighting load 30 according to the control from the operation control circuit. It is equipped with a dimming circuit. That is, the power supply board 440 executes power supply from the AC power supply to the lighting load 30 via the power supply wiring 20 according to the operation received by the touch panel 220. A connection terminal connected to the power supply wiring 20 is provided on the rear side of the power supply board 440. The connection terminal is arranged in the internal space of the body. The connection terminal may be mounted on the rear surface of the power supply board 440. The connection terminal is made of metal, for example. The insulating sheet 430 is arranged so that at least a part thereof overlaps with the connection terminal when viewed in a plan view from the X-axis direction. The power supply circuit has, 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 having a predetermined voltage. The plurality of electronic components include, for example, a transformer, a capacitor, a resistor, and the like. Transformers, capacitors, resistors, etc. are mounted on the rear surface of the power supply board 440, for example. In such a case, it is possible to suppress the influence of heat or electromagnetic field generated from electronic components such as transformers, capacitors and resistors on the antenna, display control circuit, wireless communication control circuit, operation control circuit and the like.

Hereinafter, the antenna provided on the control board 500 will be described, but as a premise thereof, the control board 600 to be compared with the control board 500 will be described first in order to clarify the problem with respect to the antenna. The control board 600 is arranged in the operation device 100 instead of the control board 500, for example. 4 (a)-(c) show the configuration of the control board 600 to be compared and the directivity by the inverted F-type antenna 630. FIG. 4A shows the configuration of the control board 600, and 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. A ground element 620 and an inverted F-type antenna 630 are mounted on the second surface 612. The inverted-F antenna 630 is an antenna for a specific low power radio that uses the first frequency band. Since the ground element 620 and the inverted F-type antenna 630 are known techniques, description thereof will be omitted here.

FIG. 4B shows the directivity of the inverted F-type antenna 630 alone. As shown in the figure, the directivity of the inverted F-type antenna 630 alone is close to omnidirectional. FIG. 4C shows the directivity of the inverted-F antenna 630 including the power supply wiring 20. In the operating device 100, which is required to be miniaturized, the size of the first surface 610 is limited. The size of the inverted-F antenna 630 is defined by the frequency band used, for example, the 920 MHz band. Under such circumstances, it may not be possible to secure a sufficient size for the ground element 620. If the ground element 620 is not large enough, the inverted F antenna 630 also causes a current distribution in the ground element 620. The high-frequency current generated in this way flows to the power supply wiring 20 via the relay board 420 and the power supply board 440 and radiates. As a result, the radiated electric field from the inverted-F antenna 630 and the radiated electric field from the power supply wiring 20 are combined, and the directivity has a distorted shape as shown in FIG. 4 (c).

In order to make the antenna directivity when the power supply wiring 20 is included close to omnidirectional, the antenna according to this embodiment is shown as shown in FIGS. 5 (a)-(c). 5 (a)-(c) show the configuration of the control board 500 and the directivity of the folded dipole antenna 550. FIG. 5A shows the configuration of the control board 500, and the ground element 520 and the folded dipole antenna 550 are arranged on the second surface 512 of the control board 500. The folded dipole antenna 550 may be formed as a pattern on a printed circuit board with a metal or the like, or may be separately made of a metal or the like and attached to the folded dipole antenna 550.

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 an antenna for a specific low power radio using the first frequency band. The loop-shaped element forming the folded dipole antenna 550 includes an element first portion 540 and an element second portion 542 that are different from each other. The element first portion 540 extends while bending from the first connection point 530 to the first turn-back point 532, and returns while bending from the first turn-around point 532 to the intermediate point 534. The element second portion 542 extends while bending from the intermediate point 534 to the second turn-around point 536, and returns while bending from the second turn-around point 536 to the second connection point 538. Here, the first connection point 530, the first turn-back point 532, the intermediate point 534, the second turn-back point 536, and the second turn-back point 536 are arranged near the center in the left-right direction of the second surface 512. Further, 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 second turning point. The length from 536 to the second connection point 538 is approximately 1/4 wavelength.

FIG. 5B shows the directivity of the folded dipole antenna 550 alone. As shown in the figure, the directivity of the folded dipole antenna 550 alone is close to omnidirectional. FIG. 5C shows the directivity of the folded dipole antenna 550 including the power supply wiring 20. The directivity shown in FIG. 5 (c) is closer to omnidirectional than the directivity shown in FIG. 4 (c). This is because, in the folded dipole antenna 550, the high frequency current is confined in the dipole antenna, so that the influence of the power supply wiring 20 on the directivity is reduced. The folded dipole antenna 550 in FIG. 5A is mounted on the second surface 512 of the control board 500 facing the second surface 120 side. This is to reduce the influence of the finger operating the touch panel 220.

FIG. 6 shows another configuration of the control board 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 up-down direction. The second side 516 is longer than the first side 514. A ground element 520 and a folded dipole antenna 550 are arranged on such a second surface 512. The ground element 520 and the folded dipole antenna 550 may be arranged on the first surface 510 of the control board 500. The element first portion 540 extends while bending from the first connection point 530 to the first turn-back point 532, and returns while bending from the first turn-around point 532 to the intermediate point 534. In particular, in the element first portion 540, the portion arranged along the first side 514 without bending is made longer than the portion arranged along the second side 516 without bending. At least a part of the element first portion 540 is arranged along the first side 514 of the control board 500. At least a part of the first part of the element is arranged along the second side 516 of the control board 500. At least a part of the element first portion 540 is arranged along the fourth side facing the second side of the control board 500.

On the other hand, the element second portion 542 extends while bending from the intermediate point 534 to the second turn-back point 536, and returns while bending from the second turn-back point 536 to the second connection point 538. In particular, in the element second portion 542, the portion arranged along the second side 516 without bending is made longer than the portion arranged along the first side 514 without bending. That is, the element first portion 540 is arranged mainly along the first side 514, and the element second portion 542 is arranged mainly along the second side 516. Again, the length from the first connection point 530 to the first turnaround point 532, the length from the first turnaround point 532 to the midpoint 534, the length from the midpoint 534 to the second turnaround point 536, the second turnaround point. The length from the point 536 to the second connection point 538 is approximately 1/4 wavelength. At least a portion of the element second portion 542 is arranged along the second side 516 of the control board 500. At least a part of the element second portion 542 is arranged along the third side facing the first side 514 of the control board 500. The length along the second side 516 of the element second portion 542 is larger than the length along the fourth side of the element first portion 540. The length along the first side 514 of the element first portion 540 is larger than the length along the third side of the element second portion 542.

A wireless communication control circuit (hereinafter referred to as "first wireless communication control circuit 570") for executing wireless communication using the folded dipole antenna 550 is arranged on the second surface 512. The first wireless communication control circuit 570 has a communication function by the specified low power radio, and executes the first wireless communication 60 with another operating device 100. Further, the first wireless communication control circuit 570 may be arranged on the first surface 510. When the folded dipole antenna 550 and the first wireless communication control circuit 570 are arranged on different surfaces of the control board, the first wireless communication control circuit 570 is the folded dipole antenna 550 via a through hole provided in the control board 500. Connected to.

The inverted F-type 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 region 522 is provided in a part of the ground element 520, and an inverted F-type antenna 560 is mounted in the notch region 522. The inverted-F antenna 560 is an antenna for BLE that uses the second frequency band. Since the second frequency band is higher than the first frequency band, the inverted F-type antenna 560 is smaller than the folded dipole antenna 550. Therefore, since the size of the ground element 520 is sufficient for the inverted F type antenna 560, the directivity of the inverted F type antenna 560 is not easily affected by the power supply wiring 20. A wireless communication control circuit (hereinafter referred to as "second wireless communication control circuit 572") for executing wireless communication using the inverted F-type antenna 560 is arranged on the first surface 510. When the inverted F-type antenna 560 and the second wireless communication control circuit 572 are arranged on different surfaces of the control board, the second wireless communication control circuit 572 has a through hole (not shown) provided in the control board 500. It is connected to the inverted F type antenna 560 via.
