In other words, the protruding portion 522 is provided at the other end of the flat portion 521 on the opposite side to the one end on the axis 514 side, and protrudes to the front of the flat portion 521 along the entire length along the direction of the shaft 514. The protruding portion 522 is formed to protrude further toward the lower side, that is, closer to the lower end edge of the switch handle 52.

When the protruding portion 522 of the switch handle 52 is pressed backward, the switch handle 52 is rotated around a portion supported by a pair of shafts 514 as a fulcrum. As a result, the button 511 is pressed by the switch handle 52 to switch the state of the contact (on / off).

Here, considering the ease of pressing the switch handle without the protruding portion 522, the size of the flat portion 521 in the front-rear direction is increased. At this time, the entire flat portion 521 protrudes forward to improve the ease of pressing the switch handle. However, the effect that the wiring device system is easy to look thin when viewed from the up-down or left-right direction cannot be expected. On the other hand, in the case of the switch handle without the protruding portion 522, considering the effect that the wiring device system is easy to look thin, and the size of the flat portion 521 in the front-back direction is small, the effect that the wiring device system is easy to look thin is expected, but It is not easy to press the switch handle. On the other hand, since the switch handle 52 of this embodiment has a protruding portion 522, the ease of pressing the switch handle 52 can be improved. In addition, in the switch handle 52 of this embodiment, only the protruding portion 522 can be protruded forward, and the size of the flat portion 521 in the front-rear direction is small. Therefore, it is expected that the wiring device system 101 can easily look thin.

An oblong light-transmitting portion 523 is provided on the upper side of the switch handle 52 and also in the central portion in the left-right direction. The light-transmitting portion 523 is configured by embedding a light-transmitting member inside a hole penetrating the switch handle 52 in the front-rear direction. The light transmitting portion 523 allows light emitted from the lamp cover 512 to pass therethrough, so that light emitted from the light bulb is emitted to the outside.

Therefore, the user can confirm the position of the wiring appliance system 101 by looking at the light-transmitting portion 523 even when the surroundings are dark. In addition, the user can know the state of the contacts of the wiring device 5, that is, the operating state of the load, by viewing the color of the light transmitting portion 523. For example, since the light transmitting part 523 emits green light when the light of the bulb is green, the user can know that the load is operating.

(3) Method and structure for assembling a board for a wiring device The board 10 for a wiring device according to this embodiment is assembled as follows. The premise is that it is assumed that the third plate 3 has been installed on the mounting frame 4 by overlapping one pair of coupling holes 423 of the mounting frame 4 with one pair of screw holes 35 of the third plate 3 and locking them with fixing screws. First, the user presses the second plate 2 against the first plate 1 from the rear. Thereby, the plurality of mounting protrusions 25 of the second plate 2 can be respectively fitted into the plurality of mounting recesses 151 of the first plate 1, and the first plate 1 and the second plate 2 can be combined with each other (first procedure). At this time, the plurality of positioning protrusions 18 of the first plate 1 are located in the plurality of positioning recesses 27 of the second plate 2, respectively, so that the short direction (up and down direction) of the first plate 1 and the second plate 2 and Movement in the vertical direction (left-right direction). Moreover, at this time, the second plate 2 is located outside the protruding wall 15 of the first plate 1.

Next, the user presses the pair of the first plate and the third plate 3 combined with the second plate 2 from the front. Accordingly, the plurality of hook protrusions 16 of the first plate 1 can be respectively inserted into the plurality of mounting holes 34 of the third plate 3. Then, the plurality of hook protrusions 16 are hooked by the edges of the plurality of mounting holes 34, respectively, and the first plate 1 and the third plate 3 are combined with each other (second procedure). At this time, the first restricting portion 361 of the convex portion 36 of the third plate 3 is located in the first concave portion 152 of the first plate 1, and the first plate 1 and the third plate 3 are restricted from each other in the short direction (up and down direction). mobile. At this time, the third plate 3 is located inside the protruding wall 15 of the first plate 1. Furthermore, the second restricting portion 362 of the convex portion 36 of the third plate 3 is located in the second concave portion 26 of the second plate 2 to restrict the second plate 2 and the third plate 3 from each other in the short direction (up and down direction). mobile.

As described above, the user follows the first procedure and the second procedure, thereby combining the first board 1, the second board 2, and the third board 3 to assemble the wiring device board 10.

In this embodiment, in a state where the wiring device board 10 is mounted on the mounting frame 4, the front surface of the wiring device 5 (here, the front surface of the switch handle 52) passes through the first opening window 11, the second opening window 21, and the third The window 31 is opened and exposed to the outside. That is, the first plate 1 is mounted on the wiring device 5 mounted on the construction surface A1 so that the front surface of the wiring device 5 is located inside the first opening window 11 when viewed from the front. Similarly, the second plate 2 is mounted on the wiring device 5 such that the front surface of the wiring device 5 is located inside the second opening window 21 when viewed from the front. Similarly, the third plate 3 is mounted on the wiring device 5 such that the front surface of the wiring device 5 is located inside the third opening window 31 when viewed from the front.

In this embodiment, neither the first plate 1 nor the second plate 2 is directly mounted on the wiring device 5, but the third plate 3 and the mounting frame 4 are indirectly mounted on the wiring device 5. The third plate 3 is not directly mounted on the wiring device 5 but is indirectly mounted on the wiring device 5 using the mounting frame 4.

Here, as shown in FIG. 1, in a state where the first plate 1 and the second plate 2 are combined with each other, the second plate 2 is located behind the first plate 1. As shown in FIG. 2, one pair of first vertical pieces 12 and one pair of first horizontal pieces 13 of the first plate 1 cover one pair of second vertical pieces 22 and one pair of second horizontal pieces 23 of the second plate 2. One of these portions (here, the outer periphery) overlaps in the front-rear direction. That is, a part (here, the outer periphery) of the second plate 2 overlaps the first plate 1 in the front-rear direction.

Furthermore, as shown in FIG. 2, since the outer peripheral shape of the second plate 2 is larger than the outer peripheral shape of the first plate 1, the second plate 2 is viewed from the front when the first plate 1 and the second plate 2 are combined with each other. When protruding to the outside of the first plate 1. That is, the second plate 2 has an outer peripheral portion 24 protruding from the outer peripheral edge of the first plate 1 in a direction crossing the front-rear direction (here, upward, downward, leftward, and rightward).

Moreover, in this embodiment, as shown in FIG. 2, the outer peripheral part 24 is extended over the entire circumference of the second plate 2. That is, in this embodiment, when the second plate 2 is viewed from the front, it protrudes to the outside of the first plate 1 over the entire circumference. With this structure, compared with the case where the outer peripheral portion 24 is intermittently provided along the outer peripheral edge of the second plate 2, the appearance of the wiring device board 10 can be improved.

Furthermore, as shown in FIGS. 1 and 5, in a state where the first plate 1 and the second plate 2 are combined with each other, the front surface of the outer peripheral edge of the first plate 1 and the front surface of the outer peripheral portion 24 of the second plate 2 There are steps. That is, the wiring device plate 10 further includes a step portion 14 between the outer peripheral edge of the first plate 1 and the outer peripheral portion 24 of the second plate 2 in the front-rear direction.

Furthermore, as shown in FIGS. 5 and 6, the closer the first plate 1 is to the two end edges in the up-down direction, the smaller the distance between the front surface in the front-back direction and the construction surface A1. Specifically, the pair of first vertical pieces 12 is formed to be approximately parallel to a plane orthogonal to the front-rear direction (in other words, the construction surface A1). On the other hand, the upper first lateral piece 13 is curved so that the closer it is to the upper end edge of the first plate 1, the smaller the distance between the front surface in the front-rear direction and the construction surface A1. In addition, the lower first horizontal piece 13 is curved so that the closer it is to the lower end edge of the first plate 1, the smaller the distance between the front surface in the front-rear direction and the construction surface A1.

As shown in FIG. 5 and FIG. 6, the second plate 2 is formed closer to both end edges of the up-down direction (the first direction orthogonal to the front-back direction), and the distance between the front surface in the front-back direction and the construction surface A1 increases. small. Specifically, the pair of second vertical pieces 22 is formed approximately parallel to a plane (in other words, the construction surface A1) orthogonal to the front-rear direction. On the other hand, the second cross piece 23 on the upper side is curved so that the closer to the upper end edge of the second plate 2 is, the smaller the distance between the front surface in the front-rear direction and the construction surface A1 is. In addition, the lower second horizontal piece 23 is formed closer to the lower end edge of the second plate 2, and the distance between the front surface in the front-rear direction and the construction surface A1 decreases.

(4) Effect In the wiring device board 10 of this embodiment, both the first board 1 and the second board 2 are formed closer to both end edges in the first direction (up and down direction), and the distance between the front face and the construction surface A1. The smaller. Therefore, when the wiring device board 10 of this embodiment is installed on the construction surface A1, the first plate 1 and the second plate 2 can be separated from the construction surface A1 at the boundary between the first plate 1 and the second plate 2 and the construction surface A1. The amount of protrusion of the construction surface A1 is small. In other words, in the state where the wiring device board 10 according to this embodiment is mounted on the construction surface A1, the amount of protrusion from the construction surface A1 can be made small. Therefore, in the wiring device board 10 of this embodiment, since the boundary between the wiring device board 10 and the construction surface A1 is hardly noticeable, the effect that the wiring device board 10 is easy to look thin can be expected.

In addition, in the wiring device board 10 of this embodiment, it is not easy to generate a step at the boundary between the first plate 1 and the second plate 2 and the construction surface A1, so it is difficult to apply external stress to the wiring device plate 10. That is, the wiring device board 10 according to this embodiment can also increase the strength against external stress.

Here, the front surface of the first plate 1 is flush with the front surface of the pair of first vertical pieces 12. The pair of first vertical pieces 12 is formed approximately parallel to the construction surface A1. That is, in the present embodiment, the front surface of the first plate 1 is flat in a second direction (left-right direction) orthogonal to both the front-rear direction and the first direction (up-down direction). The front surface of the second plate 2 is flush with the front surface of the pair of second vertical pieces 22. The pair of second vertical pieces 22 are formed approximately parallel to the construction surface A1. That is, in this embodiment, the front surfaces of each of the first plate 1 and the second plate 2 are flat in the second direction (left-right direction) orthogonal to both the front-back direction and the first direction (up-down direction). In this structure, the first plate 1 and the second plate 2 are easy to give the user a deep impression compared to the structure in which the outer peripheral edges of the front surfaces of the first plate 1 and the second plate 2 are extended around the entire circumference.

In this embodiment, as shown in FIG. 5, the front surfaces of the first plate 1 and the second plate 2 are formed so as to be convex forward. Furthermore, in a state where the first plate 1 and the second plate 2 are combined with each other, the front surface of the first plate 1 is bent along the front surface of the second plate 2. Compared with the structure in which the front surface of the first plate 1 is not curved along the front surface of the second plate 2 in this structure, the appearance can be improved. For example, if the curvature of the front surface of the first plate 1 and the curvature of the front surface of the second plate 2 are not approximately the same, there is a possibility that the physical sense of one of the first plate 1 and the second plate 2 is lost and the aesthetics is destroyed. .

In this embodiment, as shown in FIG. 12, the rear end portion 1A of the outer peripheral edge of the first plate 1 has a shape with rounded corners in plan view. Therefore, a gap 19 is provided between the outer peripheral edge of the first plate 1 and the outer peripheral portion 24 of the second plate 2. In other words, the wiring device board 10 of this embodiment has a gap 19 between the outer peripheral edge of the first plate 1 and the outer peripheral portion 24 of the second plate 2 in the front-rear direction. In this structure, by inserting a jig such as a flat-bladed screwdriver or inserting a finger through the gap 19, the first plate 1 can be easily removed from the second plate 2 using the principle of leverage. Moreover, with this structure, compared with the case where the gap 19 is not provided, the user can expect the first plate 1 to be easily observed, and as a result, the effect that the wiring device plate 10 easily looks thinner can be expected.

Moreover, in this embodiment, the front-end | tip part 2A of the outer peripheral edge of the 2nd plate 2 is formed in the shape with a rounded corner in plan view. That is, both the rear end portion 1A of the outer peripheral edge of the first plate 1 and the front end portion 2A of the outer peripheral edge of the second plate 2 have a curvature greater than zero. With this configuration, compared with the case where the rear end portion 1A on the outer peripheral edge of the first plate 1 and the front end portion 2A on the outer peripheral edge of the second plate 2 are sharp, the effect of making it easier to look thinner is expected.

In the present embodiment, as shown in FIG. 6, both end portions in the left-right direction of the second plate 2 are formed in a shape cut along a plane along the oblique rear. Therefore, both end portions in the left-right direction of the second plate 2 have end faces 28 along the oblique rear. That is, both end surfaces of the second plate 2 in the second direction (left-right direction) orthogonal to both the front-back direction and the first direction (up-down direction) face toward the rear. With this structure, even when the work surface A1 is rough, when the wiring device board 10 is mounted on the work surface A1, the gap that may occur between the wiring device board 10 and the work surface A1 is not easily noticeable and can be improved. Aesthetics. In this embodiment, as shown in FIG. 7, the second vertical piece 22 on the left side of the second plate 2 is provided with a second concave portion 26, and the convex portion 36 is exposed to the outside from this second concave portion 26. Therefore, as long as the end surface 28 faces the rear, when viewed from the front, the second concave portion 26 and the convex portion 36 are not easily visually recognized, and the appearance can be improved.

＜ Modifications ＞
In addition, in this embodiment, a part of the second plate 2 (here, the outer peripheral edge) protrudes to the outside of the first plate 1 as the outer peripheral portion 24, and may have other structures. For example, the second plate 2 may not have the outer peripheral portion 24. At this time, the outer peripheral edge of the second plate 2 may be flush with the outer peripheral edge of the first plate 1, or may be inward than the outer peripheral edge of the first plate 1.

Moreover, in the wiring device plate 10 of this embodiment, the reflection coefficient of light of the second plate 2 may be smaller than the reflection coefficient of light of the first plate 1. Specifically, white coating with a large reflection coefficient of light may be applied to the front surface of the first plate 1, and black coating with small reflection coefficient of light may be applied to the front surface of the second plate 2. With this configuration, the user can more easily look at the first plate 1 than the second plate 2, and the effect that the wiring device plate 10 can be easily seen to be thin can be expected. Of course, the relationship between the reflection coefficient of the light of the first plate 1 and the reflection coefficient of the light of the second plate 2 is not limited to the above relationship. For example, a structure in which the reflection coefficient of light of the first plate 1 is smaller than the reflection coefficient of light of the second plate 2 may be adopted. In addition, the coloring of the first plate 1 and the second plate 2 is not limited to the combination of white and black, and may be, for example, a combination of white and silver or cobalt blue, or a combination of gray and silver. In addition, the coloring of the first plate 1 and the second plate 2 may be a combination of shades of the same color, such as white. In addition, the coloring is not limited to the application, and for example, the first plate 1 and the second plate 2 may have a structure that exhibits a color.

In the present embodiment, the first plate 1, the second plate 2, and the third plate 3 are configured by different members from each other, and may have other structures. For example, the first plate 1 and the second plate 2 may also be integrated.

In addition, in this embodiment, the protruding wall 15 is continuously formed over the entire circumference of the first plate 1, and may have other structures. For example, the protruding wall 15 may have a plurality of walls, and the plurality of walls may be arranged at intervals along the outer periphery of the first plate 1.

In the present embodiment, the wiring device 5 is a key switch or a so-called rocker type (rocker type) switch.

The wiring device system 101 of the present embodiment has a configuration including only one wiring device 5, and may have a configuration including a plurality of wiring devices 5.

In the present embodiment, the wiring device board 10 is rectangular when viewed from the front, and may be square when viewed from the front. The wiring device board 10 may be non-rectangular when viewed from the front, and may be circular or polygonal when viewed from the front, for example.

In this embodiment, the first opening window 11, the second opening window 21, and the third opening window 31 are all rectangular when viewed from the front, and may be square when viewed from the front. Furthermore, the first opening window 11, the second opening window 21, and the third opening window 31 may be non-rectangular when viewed from the front, and may be circular or polygonal when viewed from the front, for example. That is, the first opening window 11, the second opening window 21, and the third opening window 31 all need to have a shape in which the front surface of the wiring device 5 can be viewed from the outside.

Furthermore, in the wiring device board 10 according to this embodiment, the second plate 2 may have a recessed portion that is recessed rearward along the entire periphery of the outer periphery of the second opening window 21. In addition, the first plate 1 may have a structure that is placed in a recessed portion of the second plate 2. With this configuration, the thickness of the wiring device board 10 can be reduced by the size (thickness) amount in the front-rear direction of the recess.

(5) Summarizing As described above, the wiring board 10 for the first aspect includes the first board 1 and the second board 2. The first plate 1 has a first opening window 11 penetrating in the front-rear direction. The second plate 2 has a second opening window 21 penetrating in the front-rear direction, and is located behind the first plate 1. The first plate 1 is mounted on the wiring device 5 mounted on the construction surface A1 so that the front surface of the wiring device 5 is located inside the first opening window 11 when viewed from the front. The second plate 2 is mounted on the wiring device 5 such that the front surface of the wiring device 5 is located inside the second opening window 21 when viewed from the front. A part (here, the outer periphery) of the second plate 2 overlaps the first plate 1 in the front-rear direction. The first plate 1 and the second plate 2 are both formed to be closer to both end edges of the first direction (up and down direction) orthogonal to the front-back direction, and the distance between the front surface and the construction surface A1 in the front-back direction is smaller.

According to this configuration, in a state where the wiring device plate 10 is mounted on the construction surface A1, the amount of protrusion from the construction surface A1 can be made small, so that the wiring device plate 10 can be expected to look thinner.

Moreover, the wiring board 10 for wiring apparatus of a 2nd aspect is the 1st aspect, and the 2nd board | substrate 1 and the 2nd board 2 have the front surface of the 2nd board | substrate perpendicular | vertical to both the front-back direction and the 1st direction (up-down direction). The direction (left-right direction) is flat.

According to this structure, the first plate 1 and the second plate 2 are easy to give a deep impression to the user, compared to the structure in which the outer peripheral edges of the front surfaces of the first plate 1 and the second plate 2 are extended all around. However, this structure is not necessary, and the front surfaces of the first plate 1 and the second plate 2 may not be formed flat in the second direction. For example, the first plate 1 and the second plate 2 may also be formed so that the closer to the two end edges in the second direction, the smaller the distance between the front surface and the construction surface A1 in the front-rear direction.

Moreover, the wiring device board 10 of a 3rd aspect is a 1st or 2nd aspect, and the front surface of the 1st board 1 is curved along the front surface of the 2nd board.

According to this structure, compared with the structure in which the front surface of the first plate 1 is not curved along the front surface of the second plate 2, the aesthetic appearance can be improved. However, this structure is not necessary, and the front surface of the first plate 1 may not be bent along the front surface of the second plate 2.

Further, in the fourth aspect of the wiring device board 10, the rear end portion 1A of the outer peripheral edge of the first plate 1 and the front end portion 2A of the outer peripheral edge of the second plate 2 are in any of the first to third aspects. Both have a curvature greater than zero.

According to this structure, compared with the case where the rear-end part 1A of the outer peripheral edge of the first plate 1 and the front-end part 2A of the outer peripheral edge of the second plate 2 are sharp, the effect of being easy to look thin can be expected. However, this structure is not necessary, and the rear end portion 1A of the outer peripheral edge of the first plate 1 and the front end portion 2A of the outer peripheral edge of the second plate 2 may be sharp.

In addition, in the fifth aspect, the wiring device board 10 is a second direction (left and right) perpendicular to both the front and back direction of the second plate 2 and the first direction (up and down direction) in any of the first to fourth aspects. Direction) with both end faces facing backward.

According to this structure, even when the construction surface A1 has unevenness and the like, and the construction surface A1 is rough, when the wiring device board 10 is mounted on the construction surface A1, a gap may be generated between the wiring device plate 10 and the construction surface A1. Less noticeable, but can improve aesthetics. However, this structure is not necessary, and the two end surfaces in the second direction of the second plate 2 may be surfaces along the front-rear direction and may also face forward. In addition, both end surfaces in the first direction of the second plate 2 may face rearward.

The wiring device system 101 of the sixth aspect includes the wiring device board 10 of any one of the first to fifth aspects, and the wiring device 5 on which the wiring device board 10 is mounted.

According to this structure, it is possible to realize a wiring device system 101 in which the wiring device plate 10 can be projected from the working surface A1 in a state of being mounted on the working surface A1.

The wiring device system 101 of the seventh aspect is the sixth aspect, and the wiring device 5 is a switch. The wiring appliance system 101 further includes a switch handle 52 for operating a switch. The switch handle 52 is configured to be rotatable with a shaft 514 orthogonal to the front-rear direction as a fulcrum. The switch handle 52 includes a flat portion 521 and a protruding portion 522 provided on the other end (lower end) of the flat portion 521 on the side opposite to the one end on the shaft 514 side. The protruding portion 522 protrudes to the front of the flat portion 521 along the entire length in the direction (left-right direction) of the shaft 514.

According to this configuration, the ease of pressing the switch handle 52 can be improved, and the effect that the wiring appliance system 101 can be easily seen as thin can be expected. However, this structure is not necessary, and the switch handle 52 may be composed of only the flat portion 521, for example.
