Further, the projecting portion 522 is formed so as to project forward as it goes downward, that is, as it approaches the lower end edge of the switch handle 52.

When the protruding portion 522 of the switch handle 52 is pushed backward, the switch handle 52 rotates about a portion supported by the pair of shafts 514 as a fulcrum. As a result, the push button 511 is pushed by the switch handle 52, and the contact state (open / closed) is switched.

Here, in the switch handle not provided with the protruding portion 522, it is conceivable to increase the dimension of the flat portion 521 in the front-rear direction in consideration of the ease of pushing. In this case, since the flat portion 521 protrudes forward as a whole, the ease of pushing the switch handle is improved, but the effect that the wiring equipment system is easily seen thin when viewed from the vertical or horizontal direction cannot be expected. .. On the other hand, in the switch handle not provided with the protrusion 522, if the dimension of the flat portion 521 in the front-rear direction is reduced in consideration of the effect that the wiring equipment system is easy to see thin, the effect that the wiring equipment system is easy to see thin can be expected. , It becomes difficult to push the switch handle. On the other hand, since the switch handle 52 of the present embodiment includes the protruding portion 522, the ease of pushing the switch handle 52 can be improved. Further, in the switch handle 52 of the present embodiment, since only the protruding portion 522 is projected forward and the dimension of the flat portion 521 in the front-rear direction can be reduced, the effect that the wiring device system 101 can be easily seen can be expected. ..

An oval-shaped translucent portion 523 is provided on the upper side of the switch handle 52 and at the center portion in the left-right direction. The translucent portion 523 is configured by embedding a translucent member inside a hole that penetrates the switch handle 52 in the front-rear direction. The light transmitting unit 523 transmits the light emitted from the lamp cover 512 to emit the light emitted by the lamp to the outside.

Therefore, the user can confirm the position of the wiring device system 101 even when the surroundings are dark by looking at the translucent unit 523. Further, the user can know the contact state of the wiring device 5, that is, the operating state of the load by looking at the color of the translucent unit 523. For example, when the light of the lamp is green, the translucent unit 523 glows green, so that the user can know that the load is in operation.

(3) Assembling Method and Configuration of Plate for Wiring Equipment The plate 10 for wiring equipment of the present embodiment is assembled as follows. As a premise, it is assumed that the third plate 3 is previously attached to the mounting frame 4 using fixing screws. First, the user presses the second plate 2 against the first plate 1 from behind. As a result, the plurality of mounting protrusions 25 of the second plate 2 are fitted into the plurality of mounting recesses 151 of the first plate 1, respectively, and the first plate 1 and the second plate 2 are coupled to each other (first procedure). .. Further, 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 first plate 1 and the second plate 2 are located in the lateral direction (up and down). Direction) and longitudinal (left-right) movement are restricted to each other. Further, 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 to which the second plate 2 is bonded from the front against the third plate 3. As a result, the plurality of hooking protrusions 16 of the first plate 1 are inserted into the plurality of mounting holes 34 of the third plate 3, respectively. Then, the first plate 1 and the third plate 3 are coupled to each other by hooking the plurality of hooking protrusions 16 on the edges of the plurality of mounting holes 34 (second procedure). At this time, the first regulating 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, so that the first plate 1 and the third plate 3 are in the lateral direction (up and down). Movement in the direction) is regulated by each other. At this time, the third plate 3 is located inside the protruding wall 15 of the first plate 1. Further, the second regulating 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, so that the second plate 2 and the third plate 3 are in the lateral direction (vertical direction). ) Are regulated by each other.

As described above, the user steps through the first procedure and the second procedure, and the first plate 1, the second plate 2, and the third plate 3 are combined to assemble the wiring instrument plate 10.

In the present embodiment, in a state where the wiring fixture plate 10 is attached to the mounting frame 4, the front surface of the wiring fixture 5 (here, the front surface of the switch handle 52) is the first opening window 11, the second opening window 21, and so on. And it is exposed to the outside through the third opening window 31. That is, the first plate 1 is attached to the wiring fixture 5 attached to the construction surface A1 so that the front surface of the wiring fixture 5 is located inside the first opening window 11 when viewed from the front. Similarly, the second plate 2 is attached to the wiring device 5 so 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 attached to 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 the present embodiment, both the first plate 1 and the second plate 2 are not directly attached to the wiring fixture 5, but are indirectly attached to the wiring fixture 5 by using the third plate and the mounting frame 4. ing. Further, the third plate 3 is not directly attached to the wiring instrument 5, but is indirectly attached to the wiring instrument 5 by using the attachment frame 4.

Here, as shown in FIG. 1, the second plate 2 is located behind the first plate 1 in a state where the first plate 1 and the second plate 2 are bonded to each other. Further, as shown in FIG. 2, the pair of first vertical pieces 12 and the pair of first horizontal pieces 13 of the first plate 1 are the pair of second vertical pieces 22 and the pair of second horizontal pieces of the second plate 2. With respect to 23, they overlap in the front-rear direction so as to cover a part of them. That is, a part of the second plate 2 overlaps with the first plate 1 in the front-rear direction.

Then, 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 1 and the second plate 2 are in a state of being coupled to each other. The plate 2 projects outward from the first plate 1 when viewed from the front. 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 the front-rear direction (here, upward, downward, leftward, rightward).

Further, in the present embodiment, the outer peripheral portion 24 is provided over the entire circumference of the second plate 2 as shown in FIG. That is, in the present embodiment, the second plate 2 projects outward from the first plate 1 over the entire circumference when viewed from the front. In this configuration, the appearance of the wiring instrument plate 10 can be improved as compared with the case where the outer peripheral portion 24 is provided intermittently along the outer peripheral edge of the second plate 2.

Further, as shown in FIGS. 1 and 5, in a state where the first plate 1 and the second plate 2 are connected 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 is a step between and. That is, the wiring instrument 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 in the front-rear direction.

Then, as shown in FIGS. 5 and 6, the first plate 1 is formed so that the distance between the front surface and the construction surface A1 in the front-rear direction becomes smaller as it approaches both end edges in the vertical direction. Specifically, the pair of first vertical pieces 12 are formed so as to be substantially parallel to a plane (in other words, a construction surface A1) orthogonal to the front-rear direction. On the other hand, the upper first horizontal piece 13 is curved so that the distance between the front surface and the construction surface A1 in the front-rear direction becomes smaller as it approaches the upper end edge of the first plate 1. Further, the lower first horizontal piece 13 is formed to be curved so that the distance between the front surface and the construction surface A1 in the front-rear direction becomes smaller as it approaches the lower end edge of the first plate 1.

Further, as shown in FIGS. 4 and 5, the distance between the front surface and the construction surface A1 in the front-rear direction is closer to both end edges of the second plate 2 in the vertical direction (first direction orthogonal to the front-rear direction). Is formed so as to be small. Specifically, the pair of second vertical pieces 22 are formed so as to be substantially parallel to a plane (in other words, a construction surface A1) orthogonal to the front-rear direction. On the other hand, the upper second horizontal piece 23 is curved so that the distance between the front surface and the construction surface A1 in the front-rear direction becomes smaller as it approaches the upper end edge of the second plate 2. Further, the lower second horizontal piece 23 is formed so that the distance between the front surface and the construction surface A1 in the front-rear direction becomes smaller as it approaches the lower end edge of the second plate 2.

(4) Effect In the wiring instrument plate 10 of the present embodiment, the first plate 1 and the second plate 2 are both closer to both end edges in the first direction (vertical direction) between the front surface and the construction surface A1. It is formed so that the distance between the two is small. Therefore, the wiring instrument plate 10 of the present embodiment is attached to the construction surface A1 and at the boundary between the first plate 1 and the second plate 2 and the construction surface A1, the first plate 1 and the second plate 2 The amount of protrusion from the construction surface A1 can be reduced. In other words, the wiring fixture plate 10 of the present embodiment can reduce the amount of protrusion from the construction surface A1 in a state of being attached to the construction surface A1. Therefore, in the wiring instrument plate 10 of the present embodiment, since the boundary between the wiring instrument plate 10 and the construction surface A1 is inconspicuous, the effect that the wiring instrument plate 10 can be easily seen can be expected.

Further, in the wiring instrument plate 10 of the present embodiment, since a step is unlikely to occur at the boundary between the first plate 1 and the second plate 2 and the construction surface A1, external stress is unlikely to be applied to the wiring instrument plate 10. That is, the wiring instrument plate 10 of the present embodiment can also improve the strength against stress from the outside.

Here, the front surface of the first plate 1 is flush with the front surface of the pair of first vertical pieces 12. Further, the pair of first vertical pieces 12 are formed so as to be substantially parallel to the construction surface A1. That is, in the present embodiment, the front surface of the first plate 1 is formed flat in the second direction (horizontal direction) orthogonal to both the front-rear direction and the first direction (vertical 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 so as to be substantially parallel to the construction surface A1. That is, in the present embodiment, the front surfaces of the first plate 1 and the second plate 2 are formed flat in the second direction (horizontal direction) orthogonal to both the front-rear direction and the first direction (vertical direction). ing. In this configuration, the first plate 1 and the second plate 2 are easily impressed by the user as compared with the configuration in which the outer peripheral edges of the front surfaces of the first plate 1 and the second plate 2 are curved over the entire circumference.

Further, in the present 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 toward the front, respectively. Then, in a state where the first plate 1 and the second plate 2 are connected to each other, the front surface of the first plate 1 is curved along the front surface of the second plate 2. In this configuration, the appearance can be improved as compared with the configuration in which the front surface of the first plate 1 is not curved along the front surface of the second plate 2. 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 substantially equal, the sense of unity between the first plate 1 and the second plate 2 may be lost, and the appearance may be impaired. ..

Further, in the present embodiment, as shown in FIG. 12, the rear end portion 1A of the outer peripheral edge of the first plate 1 is formed in a rounded shape in a 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 instrument plate 10 of the present 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 configuration, by inserting a jig such as a flat-blade screwdriver or a fingernail into the gap 19, it becomes easy to remove the first plate 1 from the second plate 2 by using the principle of leverage. Further, in this configuration, it is easier for the user to gaze at the first plate 1 as compared with the case where the gap 19 is not provided, and as a result, the effect that the plate 10 for wiring equipment can be easily seen can be expected.

Further, in the present embodiment, the front end portion 2A of the outer peripheral edge of the second plate 2 is formed in a rounded shape in a plan view. That is, 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 both have a curvature larger than zero. In this configuration, it can be expected that 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 sharper and easier to see.

Further, in the present embodiment, as shown in FIG. 6, both ends of the second plate 2 in the left-right direction are cut in a plane along the diagonally rearward portion. Therefore, both ends of the second plate 2 in the left-right direction have end faces 28 along diagonally rearward. That is, both end faces of the second plate 2 in the second direction (horizontal direction) orthogonal to both the front-rear direction and the first direction (vertical direction) are facing rearward. In this configuration, even when the construction surface A1 is rough, when the wiring equipment plate 10 is attached to the construction surface A1, the gap that may occur between the wiring equipment plate 10 and the construction surface A1 is inconspicuous. It can improve the appearance. Further, in the present embodiment, as shown in FIG. 7, a second recess 26 is provided in the second vertical piece 22 on the left side of the second plate 2, and the convex portion 36 is exposed to the outside from the second recess 26. doing.

In this case, 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 inside the outer peripheral edge of the first plate 1.

Further, in the wiring instrument plate 10 of the present embodiment, the light reflectance of the second plate 2 may be smaller than the light reflectance of the first plate 1. Specifically, a white coating having a relatively high light reflectance may be applied to the front surface of the first plate 1, and a black coating having a relatively low light reflectance may be applied to the front surface of the second plate 2. With this configuration, it is easier for the user to gaze at the first plate 1 than with the second plate 2, and the effect that the plate 10 for wiring equipment can be easily seen can be expected. Of course, the relationship between the light reflectance of the first plate 1 and the light reflectance of the second plate 2 is not limited to the above relationship. For example, the light reflectance of the first plate 1 may be smaller than the light reflectance of the second plate 2. 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.

For example, the protruding wall 15 may have a plurality of walls, and the plurality of walls may be arranged side by side at intervals along the outer peripheral edge of the first plate 1.

Further, in the present embodiment, the wiring device 5 is a piano handle type switch, but it may be a so-called rocker type (seesaw type) switch.

Further, although the wiring device system 101 of the present embodiment is configured to include only one wiring device 5, it may be configured to include a plurality of wiring devices 5.

Good. That is, the first opening window 11, the second opening window 21, and the third opening window 31 may all have a shape so that the front surface of the wiring device 5 can be seen from the outside.

Further, in the wiring instrument plate 10 of the present embodiment, the second plate 2 may have a recess recessed rearward over the entire outer peripheral edge of the second opening window 21. The first plate 1 may be placed on the recess of the second plate 2.

The protruding portion 522 projects forward of the flat portion 521 over the entire length in the direction along the shaft 514 (left-right direction).

According to this configuration, the ease of pushing the switch handle 52 can be improved, and the effect that the wiring device system 101 can be easily seen can be expected. However, this configuration is not essential, and the switch handle 52 may be composed of, for example, only the flat portion 521.
