The wiring device 5 can be mounted on the mounting frame 4 by using two pairs of mounting claws 513 in a state where the device main body 51 is inserted into the opening window 41 of the mounting frame 4. Specifically, a pair of mounting claws 513 located on the upper side of the appliance body 51 are fitted into a pair of mounting holes 431 of the transverse piece 43 on the upper side of the mounting frame 4. Next, a pair of mounting claws 513 located on the lower side of the instrument body 51 are fitted into a pair of mounting holes 431 of the transverse pieces 43 on the lower side of the mounting frame 4, respectively, whereby the instrument body 51 can be mounted on the mounting frame 4.

The switch handle 52 is formed in a rectangular shape long in the left-right direction. The switch handle 52 is formed in a size capable of being fitted into the first opening window 11, the second opening window 21, and the third opening window 31. In this embodiment, the switch handle 52 is one of the handles used when only one wiring device 5 is mounted on the mounting frame 4.

The switch handle 52 is attached to the appliance body 51 so as to cover the front surface of the appliance body 51. Specifically, a pair of columnar shafts 514 are provided on the upper side of the front surface of the instrument body 51. The pair of shafts 514 are provided on the left and right sides of the lamp cover 512. Furthermore, a bearing portion on which a pair of shafts 514 is mounted is provided at a position facing the pair of shafts 514 of the appliance body 51 on the rear surface of the switch handle 52. The switch handle 52 can be rotated by the pair of shafts 514 as a fulcrum by holding the pair of shafts 514 in the bearing portion. In other words, the switch handle 52 is configured to be rotatable as a fulcrum with a pair of axes 514 orthogonal to the front-rear direction.

The switch handle 52 includes a flat portion 521 and a protruding portion 522. The front surface of the flat portion 521 is a surface approximately parallel to a plane orthogonal to the front-rear direction when the switch handle 52 is not operated (see FIG. 11). The protruding portion 522 is provided at the lower end of the flat portion 521 and protrudes to the front of the flat portion 521 along the entire length extending in the left-right direction. In other words, the protruding portion 522 is provided at the opposite end of the one end on the shaft 514 side of the flat portion 521 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 the third plate 3 has been installed on the mounting frame 4 by overlapping a pair of coupling holes 423 of the mounting frame 4 with a pair of screw holes 35 of the third plate 3 and locking them with fixing screws, respectively. 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 fitted into the plurality of mounting recesses 151 of the first plate 1, respectively, 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, and the short direction (up and down direction) of the first plate 1 and the second plate 2 and Long (left and right) movement. 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 first plate 1 and the third plate 3 that have been combined with the second plate 2 from the front. Accordingly, the plurality of hook protrusions 16 of the first plate 1 can be inserted into the plurality of mounting holes 34 of the third plate 3, respectively. 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 coupled to 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. In addition, 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 such 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 so 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 attached to the wiring device 5 but is indirectly attached to 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 coupled to each other, the second plate 2 is located behind the first plate 1. In addition, 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 are covered with one pair of second vertical pieces 22 and one pair of second horizontal pieces 23 of the second plate 2. One of these parts overlaps in the front-back direction. That is, a part of the second plate 2 overlaps the first plate 1 in the front-rear direction.

Moreover, 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. It protrudes beyond the first plate 1 at the time. 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 intersecting with the front-rear direction (herein, upward, downward, leftward, and rightward).

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

Further, as shown in FIGS. 1 and 5, in a state where the first plate 1 and the second plate 2 are coupled to 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 that constitutes a step in the front-back direction between the outer peripheral edge of the first plate 1 and the outer peripheral portion 24 of the second plate 2.

In this embodiment, the first plate 1 is stacked on the front surface of the second plate 2. Therefore, in this embodiment, the dimension of the step portion 14 in the front-rear direction is equal to or larger than the dimension in the front-rear direction of the outer peripheral edge of the first plate 1. With this structure, the effect of ensuring the strength of the first plate 1 and making the wiring device plate 10 easily look thin can be expected.

In this embodiment, as shown in FIG. 12, the rear end of the outer peripheral edge of the first plate 1 is formed in 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 lever principle. Moreover, with this structure, compared with the case where the gap 19 is not provided, the user can expect the 1st board 1 to be easily observed, and as a result, the effect that the wiring board 10 can be seen thin easily.

When the first plate 1, the second plate 2, and the third plate 3 are grouped together, the third plate 3 is covered with the first plate 1 when viewed from the front. That is, the first plate 1 is mounted on the third plate 3 so as to cover the entire area of the front surface of the third plate 3. In this structure, in a state where the first plate 1 and the third plate 3 are combined with each other, the third plate 3 is difficult to protrude behind the first plate 1. That is, it is easy to fit the third plate 3 into the size (thickness) of the first plate 1 in the front-rear direction. Therefore, with this structure, the wiring device board 10 can be easily made thin.

In a state where the first plate 1, the second plate 2, and the third plate 3 are grouped together, the third plate 3 is located inside the second opening window 21 (see FIG. 7). The second plate 2 is located outside the protruding wall 15, and the third plate 3 is located inside the protruding wall 15. In other words, the protruding wall 15 is located between the second plate 2 and the third plate 3. With this structure, the strength against a force applied to the first plate 1 in the front-rear direction can be increased compared with the case where the protruding wall 15 is not provided.

(4) Effect The wiring device board 10 of this embodiment has the outer peripheral portion 24 of the second plate 2, that is, the second plate 2 protrudes beyond the first plate 1 when viewed from the front. Therefore, in the wiring device board 10 of this embodiment, it is possible to increase or decrease the amount by which the outer peripheral portion 24 protrudes from the first plate 1 and so on, to make a flat design using the outer peripheral portion 24. In the wiring device board 10 according to this embodiment, the first board 1 and the second board 2 are overlapped in the front-rear direction. A step portion 14 is provided between the outer peripheral edge of the first plate 1 and the outer peripheral portion 24 of the second plate 2. Therefore, in the wiring device board 10 according to this embodiment, in addition to the design of the outer peripheral portion 24, the size of the step portion 14 in the front-rear direction is also increased or decreased, thereby utilizing the outer peripheral portion 24 and the step. The three-dimensional design of the part 14. Therefore, in the wiring device board 10 of this embodiment, the degree of freedom in design can be improved compared to a structure in which only the first board 1 and the second board 2 are arranged on the same plane.

In addition, the wiring appliance board should be installed on the construction surface and integrated into the surrounding environment without being too noticeable. Therefore, the amount of the wiring device board protruding from the construction surface should be small, that is, the size in the front-back direction should be small (thin). Here, since the wiring device board 10 of the present embodiment has a structure in which the first board 1 and the second board 2 overlap in the front-rear direction, the size (thickness) in the front-rear direction is large, and it is also considered to be thin in violation of the appearance. Condition.

However, since the wiring device board 10 according to this embodiment has the stepped portion 14, the effect of making it easy to look thin can be expected. That is, in the present embodiment, the presence of the step portion 14 makes it easier for the user to look at the first plate 1 than the second plate 2, and there is an illusion that the amount of protrusion from the construction surface A1 is small. The wiring device board 10 is easy to look thin. As described above, in the wiring device board 10 according to this embodiment, not only has the advantage that the degree of freedom in design can be improved, but also the effect that the wiring device board 10 can be easily made thin can be expected.

In the wiring device board 10 according to this embodiment, the first board 1 and the second board 2 overlap in the front-rear direction. That is, since the portion of the second plate 2 that is not covered by the first plate 1 has only the outer peripheral portion 24, the portion of the second plate 2 that is covered by the first plate 1 can be designed more freely. Therefore, in the wiring device board 10 according to this embodiment, the portion of the second vertical piece 22 of the second plate 2 covered by the first plate 1 in the left-right direction can be changed without changing the protruding amount of the outer peripheral portion 24, for example. With a large size, the strength of the second plate 2 can be increased. Alternatively, if the size of the portion covered by the first plate 1 in the second horizontal piece 23 in the vertical direction is large, the strength of the second plate 2 can be increased.

<Modifications> In the wiring device board 10 of this embodiment, the reflection coefficient of the light of the second plate 2 may be smaller than the reflection coefficient of the 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, it is easier for the user to look at the first plate 1 than the second plate 2, and it is expected that the wiring device plate 10 may look thinner easily. Of course, 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. 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 in which the color itself is developed.

Further, in the present embodiment, the first plate 1, the second plate 2, and the third plate 3 are constituted by mutually different members, and may have other structures. For example, the first plate 1 and the second plate 2 may 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.

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. In addition, the first opening window 11, the second opening window 21, and the third opening window 31 may not be rectangular when viewed from the front, and may be circular or polygonal when viewed from the front, for example. That is, all of the first opening window 11, the second opening window 21, and the third opening window 31 need only 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 extending rearwardly around the entire 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.

The first plate 1 is mounted on the wiring device 5 such 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 of the second plate 2 overlaps the first plate 1 in the front-rear direction. 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. The wiring device board 10 further includes a step portion 14 that constitutes a step in the front-back direction between the outer peripheral edge of the first plate 1 and the outer peripheral portion 24 of the second plate 2.

According to this configuration, not only has an advantage that the degree of freedom in design can be increased, but also an effect that the wiring device board 10 can be easily seen as thin can be expected.

In the second aspect, the wiring device board 10 is in the first aspect, and the dimension (thickness) of the step portion 14 in the front-rear direction is greater than or equal to the dimension (thickness) in the front-rear direction of the outer periphery of the first plate 1.

According to this configuration, the strength of the first plate 1 can be secured, and the effect that the wiring device plate 10 can be easily seen to be thin can be expected. However, this structure is not necessary, and the dimension of the step portion 14 in the front-rear direction may be smaller than the dimension in the front-rear direction of the outer periphery of the first plate 1.

In the third aspect, the wiring device board 10 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 the first or second aspect.

According to this structure, the first plate 1 can be easily removed from the second plate 2 by using a jig or a finger such as a flat screwdriver. Moreover, with this structure, compared with the case which does not have the gap 19, the effect which the wiring-equipment board 10 looks thin easily can be expected.

The first and second plates 1 and 2 are rectangular when viewed from the front, and the outer periphery 24 of the second plate 2 is 24. The thickness of the short side (the second vertical piece 22) in the front-back direction is thicker than that of the short side (the first vertical piece 12) in the outer periphery of the first plate 1 in the front-back direction.

According to this configuration, if the dimension of the outer peripheral portion 24 of the second plate 2 is thick, the strength of the second plate 2 can be increased, and the effect that the wiring device plate 10 can be easily seen to be thin can be expected. However, this structure is not necessary, and the thickness of the short side of the outer peripheral portion 24 of the second plate 2 in the front-rear direction may be equal to or thinner than the thickness of the short side of the outer peripheral portion of the first plate 1 in the front-rear direction.

The first plate 1 is mounted on the third plate 3 so as to cover the entire front surface of the third plate 3.

According to this configuration, by combining the third plate 3 with the first plate 1 and the second plate 2, the strength of the wiring device board 10 can be improved. In addition, according to this configuration, in a state where the first plate 1 and the third plate 3 are coupled to each other, the third plate 3 does not easily protrude behind the first plate 1, and therefore the wiring device plate 10 is easily made thin. However, this structure is not necessary, and the wiring board 10 may not include the third board 3. At this time, the structure may be such that the first plate 1 is directly mounted on the mounting frame 4. Moreover, even when the wiring board 10 includes the third board 3, the first board 1 may not cover the entire area of the front surface of the third board 3.

In addition, the wiring device board 10 according to the sixth aspect is the fifth aspect, and the third plate 3 is located inside the second opening window 21. The first plate 1 includes a protruding wall 15 protruding rearward from the rear surface of the first plate 1. The protruding wall 15 extends along the outer periphery of the first plate 1 and is located between the second plate 2 and the third plate 3.

According to this structure, it is possible to increase the strength against a force applied to the first plate 1 in the front-rear direction compared to the case where the projecting wall 15 is not provided.

The other of the protruding wall 15 and the second plate 2 has a mounting recess 151 on which the mounting protrusion 25 is located on the inside.

According to this structure, the strength against external forces applied to the wiring device board 10 in the front-back direction can be increased, and as a result, the stability of the wiring device board 10 during use can be improved. However, this structure is not necessary, and the protruding wall 15 and the second plate 2 may not have the mounting convex portion 25 and the mounting concave portion 151.

Further, the wiring device board 10 according to the eighth aspect is the sixth or seventh aspect, and the protruding wall 15 has a first recessed portion 152.

The third plate 3 includes a convex portion 36 (first restricting portion 361) located inside the first concave portion 152.

According to this configuration, the first plate 1 and the third plate 3 are less likely to be shifted from each other. However, this structure is not necessary, and the protruding wall 15 and the third plate 3 may not have the first concave portion 152 and the convex portion 36, respectively.

In addition, the wiring device board 10 of the ninth aspect is the eighth aspect, and the second plate 2 has a second recessed portion 26. The second recessed portion 26 is provided at a portion facing the first recessed portion 152 and is recessed forward. The convex portion 36 (the second restricting portion 362) is located inside the second concave portion 26.

With this configuration, the second plate 2 and the third plate 3 are less likely to be shifted from each other. According to this structure, the positional deviation of the first plate 1 and the third plate 3 and the positional deviation of the second plate 2 and the third plate 3 are less likely to occur by one member (the convex portion 36). In addition, according to this structure, the third plate 3 can be easily removed from the second plate 2 by using a jig or a finger such as a flat screwdriver. However, this structure is not necessary, and the second plate 2 may not have the second recessed portion 26.

In the ninth aspect, the wiring device board 10 of the tenth aspect is the second direction (up and down direction) and the size of the second recessed portion 26 perpendicular to the front-rear direction and the first direction (left-right direction). It is smaller than the size of the first recessed portion 152.

According to this structure, the strength of the convex portion 36 can be ensured, and the appearance of the wiring device board 10 is not easily damaged. However, this structure is not necessary, and in the second direction, the size of the second recessed portion 26 may be the same as or larger than the size of the first recessed portion 152.

In addition, in the wiring board 10 for the eleventh aspect, the reflection coefficient of the light of the second plate 2 is smaller than the reflection coefficient of the light of the first plate 1 in any one of the first to tenth aspects.

According to this configuration, it is easier for the user to 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. However, this structure is not necessary, and the reflection coefficient of the light of the second plate 2 may be equal to or larger than that of the light of the first plate 1.

In addition, in the twelfth aspect of the wiring device board 10, in any one of the first to eleventh aspects, the outer peripheral portion 24 is provided to extend over the entire circumference of the second panel 2.

According to this structure, compared with the case where the outer peripheral part 24 is intermittently provided along the outer peripheral edge of the second plate 2, the aesthetic appearance of the wiring device board 10 can be improved. However, this structure is not necessary, and the outer peripheral portion 24 may be provided intermittently along the outer peripheral edge of the second plate 2.

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

According to this configuration, it is possible to realize a wiring device system 101 that not only has the advantage that the degree of freedom in design can be improved, but also that the wiring device board 10 can be easily seen as thin.

(Embodiment 2) Hereinafter, a wiring device system 102 according to Embodiment 2 will be described with reference to Fig. 13. However, since the basic structure of the wiring device system 102 according to this embodiment is the same as that of the wiring device system 101 (including the modification) according to the first embodiment, the same parts are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 13, the wiring device system 102 of this embodiment is different from the first embodiment, and includes a wiring device 500 instead of the wiring device 5. The wiring device system 102 according to this embodiment is different from the first embodiment, and includes a third plate 300 instead of the third plate 3 and the mounting frame 4. Furthermore, this embodiment is different from the first embodiment in that the socket, that is, the front surface of the wiring device 500 can be exposed to the outside, so the size of the first opening window 11 of the first plate 1 is smaller than that of the first embodiment. The size of the first opening window 11.

The third plate 300 is formed in a rectangular frame shape that is long in the left-right direction by using, for example, resin.
