[0011] Hereinafter, wiring equipment boxes, wiring equipment systems, and box systems according to embodiments will be described in detail with reference to the drawings. However, the figures described in the following embodiments are schematic diagrams, and the dimensional ratios of the sizes of each component do not necessarily reflect the actual dimensional ratios. Furthermore, the configurations described in the following embodiments are merely examples of this disclosure. This disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of this disclosure can be achieved.

[0012] (Embodiment) (1) Overview The outline of the wiring equipment box 1 and wiring equipment system 200 according to this embodiment will be described with reference to the drawings.

[0013] The wiring equipment box 1 of this embodiment houses wiring equipment such as outlets or switches. The wiring equipment box 1, with the wiring equipment 100 (a switch in the figure) housed inside, is installed on a mounting surface such as a wall as a wiring equipment system 200 (see Figure 14). In other words, the wiring equipment system 200 of this embodiment comprises the wiring equipment box 1 and the wiring equipment 100 housed in the wiring equipment box 1.

[0014] The wiring equipment box 1 of this embodiment includes a first box body 11 having a storage space 10 capable of housing wiring equipment 100 (see Figures 1 and 4). The first box body 11 has a rectangular plate-shaped bottom wall 2, a first side wall 3, and a second side wall 4. The first side wall 3 is provided on the first side edge of the bottom wall 2 (see Figure 4). The second side wall 4 is provided adjacent to the first side wall 3 on the second side edge of the bottom wall 2 (see Figure 4).

[0015] The first box body 11 of the first wiring equipment box 1A is configured to be connectable to the second box body 11 of the second wiring equipment box 1B via a first outer wall surface 30 (see Figures 6 and 7). The first outer wall surface 30 is the surface of the first side wall 3 opposite to the storage space 10 (see Figures 1 and 4). The first outer wall surface 30 is provided with a first positioning part 33 for positioning the second box body 11 relative to the first box body 11 (see Figures 6 and 7). The first outer wall surface 30 corresponds to the "first wall surface" as referred to in this disclosure.

[0016] The first positioning portion 33 includes at least one of a first protrusion 331 and a first recess 332. The first protrusion 331 projects from the first outer wall surface 30 in the direction opposite to the storage space 10. The first recess 332 is recessed from the first outer wall surface 30 toward the storage space 10.

[0017] When multiple boxes are connected via a mounting device, as in Patent Document 1, the gaps between the boxes tend to become large. This creates gaps between multiple wiring devices (such as switches and outlets) installed on a wall or other construction surface, resulting in a decrease in aesthetic appeal.

[0018] Therefore, in this embodiment, the first box body 11 is configured to be connectable to the second box body 11 via the first wall surface 30, and the first positioning portion 33 is provided on the first wall surface 30 (see Figures 6 and 7). The first convex portion 331 of the first positioning portion 33 protrudes from the first outer wall surface 30 in the direction opposite to the storage space 10, and the first concave portion 332 is recessed toward the storage space 10 side relative to the first outer wall surface 30. Thus, according to the wiring equipment box 1 of this embodiment, it is possible to reduce the gap between the connected first box body 11 and the second box body 11. As a result, it is possible to suppress a decrease in the design quality of the multiple wiring equipment 100 installed on a construction surface such as a wall.

[0019] (2) Details The details of the wiring equipment box 1 and wiring equipment system 200 according to one embodiment will be described in detail below with reference to Figures 1 to 14.

[0020] In this embodiment, with the wiring equipment box 1 installed on a wall or other mounting surface, the direction perpendicular (orthogonal) to the horizontal plane is described as the "up-down direction" (Z-axis direction in Figures 1 to 5, etc.). Also, when viewing the wiring equipment box 1 from the front, the direction upward (positive direction in the Z-axis direction) is described as "up." Furthermore, the direction perpendicular to the up-down direction and parallel to the surface of the wall (X-axis direction in Figures 1 to 5, etc.) is described as the "left-right direction," and when viewing the wiring equipment box 1 from the front, the right side (positive direction in the X-axis direction) is described as "right," and the left side as "left." In addition, the direction perpendicular to both the up-down and left-right directions, that is, the direction perpendicular to the surface of the wall, is described as the "front-back direction" (Y-axis direction in Figures 1 to 5, etc.), and the back side of the wall (back of the wall) is described as "rear," and the front side of the wall (positive direction in the Y-axis direction) is described as "front." Furthermore, in the following description, the up-down direction and the left-right direction may be referred to as the first direction and the second direction, respectively. Note that the arrows indicating directions in the drawings are for illustrative purposes only and do not represent actual objects. Also, although this embodiment was described using the case where the Z-axis direction is parallel to the vertical direction as an example, it may also be installed on the construction surface with the X-axis direction parallel to the vertical direction.

[0021] (2-1) Configuration of the wiring equipment box The wiring equipment box 1 of this embodiment includes a first box body 11 capable of housing the first wiring equipment 100 (see Figure 14).

[0024] The bottom wall 2 is formed in the shape of a rectangular plate. More specifically, the bottom wall 2 is formed in the shape of a rounded rectangular plate. The inner bottom surface 20 of the bottom wall 2 is formed in the shape of a roughly rectangular shape when viewed from the front (see Figure 4). The outer bottom surface 21 of the bottom wall 2 is formed in the shape of a rounded rectangle when viewed from the rear (see Figure 5). A knockout hole 29 is provided in the center of the bottom wall 2 (see Figures 4 and 5). The knockout hole 29 is processed to easily create a mounting hole for connecting electrical conduit. The knockout hole 29 is designed to come out when an impact is applied to the surface of the bottom wall 2. When connecting electrical conduit during construction, the knockout hole 29 is punched out using a hammer or the like, creating a mounting hole that penetrates the bottom wall 2 in the thickness direction. The electrical conduit is inserted through the mounting hole.

[0025] (2-1-1) First side wall The first side wall 3 is provided on one (right) of a pair of opposing side edges in the longitudinal direction (X-axis direction in the figure) of the inner bottom surface 20 of the rectangular bottom wall 2 (see Figure 4). The first side wall 3 is formed in the shape of a rectangular plate (see Figure 3). More specifically, the first side wall 3 is formed in the shape of a rectangular plate (see Figure 3). A knockout hole 39 is provided in the center of the first side wall 3 (see Figures 1 and 3).

[0026] In the following, the direction of the first side wall 3 toward the storage space 10 of the first box body 11 (the negative direction of the X-axis in the diagram) may be referred to as the inside of the first side wall 3. Conversely, the direction opposite to the storage space 10 of the first box body 11 (the positive direction of the X-axis in the diagram) may be referred to as the outside of the first side wall 3.

[0027] The first side wall 3 includes a first inner wall surface 31 and a first outer wall surface 30 that are opposite each other in the thickness direction.

The first fixing member 32 is located at the front end of the first inner wall surface 31 (in the positive direction of the Y-axis in the figure) and at the center in the Z-axis direction. The first fixing member 32 is a member for fixing a mounting frame 101 capable of holding wiring equipment 100 to the first box body 11 (see Figure 14). The installation of wiring equipment 100 will be explained in more detail in "(2-4) Installation of Wiring Equipment".

[0029] The first outer wall surface 30 is provided with a first rib 300, a second rib 301, a third rib 302, and a fourth rib 303. In this embodiment, the first rib 300, the second rib 301, the third rib 302, and the fourth rib 303 are formed integrally with the first side wall 3.

[0030] The first rib 300 and the second rib 301 are provided opposite each other in the vertical direction (Y-axis direction in the figure) of the first outer wall surface 30. More specifically, the first rib 300 is provided on the front end side (positive side of the Y-axis in the figure) of the first outer wall surface 30 in the vertical direction (Y-axis direction in the figure). The first rib 300 protrudes outward from the first side wall 3 relative to the first outer wall surface 30 and extends vertically (Z-axis direction in the figure) along the front edge of the first side wall 3. The first rib 300 has a flattened shape. The central portion of the first rib 300 is curved upward (positive Y-axis direction in the figure) than the portions at both ends thereof.

[0031] The second rib 301 is provided on the rear end side (negative side of the Y-axis in the figure) of the first outer wall surface 30 in the vertical direction (Y-axis direction in the figure). The second rib 301 protrudes outward from the first side wall 3 relative to the first outer wall surface 30 and extends along the vertical direction (Z-axis direction in the figure). The second rib 301 has a flattened shape. The second rib 301 is formed integrally with the bottom wall 2 so as to smoothly connect with the outer bottom surface 21 of the bottom wall 2 (see Figure 5).

[0032] The third rib 302 and the fourth rib 303 are provided between the first rib 300 and the second rib 301 in the vertical direction of the first outer wall surface 30 (Y-axis direction in the figure). More specifically, the third rib 302 is provided between the upper end side of the first rib 300 (positive Z-axis direction in the figure) and the upper end side of the second rib 301 (positive Z-axis direction in the figure) in the vertical direction of the first outer wall surface 30 (Y-axis direction in the figure). The third rib 302 protrudes outward from the first side wall 3 relative to the first outer wall surface 30 and extends in a direction along the upper edge of the first side wall 3 (Y-axis direction in the figure). The third rib 302 has a flattened shape.

[0033] The fourth rib 303 is provided between the lower end of the first rib 300 (negative side in the Z-axis direction in the figure) and the lower end of the second rib 301 (negative side in the Z-axis direction in the figure) in the vertical direction of the first outer wall surface 30 (Y-axis direction in the figure). The fourth rib 303 has a flattened shape. The fourth rib 303 protrudes outward from the first side wall 3 relative to the first outer wall surface 30 and extends in a direction along the lower edge of the first side wall 3 (Y-axis direction in the figure).

[0034] Furthermore, the third rib 302 and the fourth rib 303 are provided facing each other in the vertical direction (Z-axis direction in the figure).

[0035] The first outer wall surface 30 is provided with a first connecting portion 34 and a second connecting portion 35 for connecting the first box body 11 and the second box body 11. The second box body 11 is the box body of the second wiring equipment box 1B (see Figures 6 and 7) which is connected to the first wiring equipment box 1A. The second box body 11 has the same structure as the first box body 11 of the first wiring equipment box 1A.

[0036] As shown in Figures 6 and 7, the first connecting portion 34 and the second connecting portion 35 correspond to a connecting structure for connecting the first box body 11 and the second box body 11. In other words, the first connecting portion 34 and the second connecting portion 35 correspond to the "multiple first connecting portions" as referred to in this disclosure. The first connecting portion 34 and the second connecting portion 35 are provided at different height positions in the vertical direction (Y-axis direction in the figures) of the first outer wall surface 30. In other words, the first connecting portion 34 and the second connecting portion 35 are provided at multiple height positions in the normal direction (Y-axis direction in the figures) of the surface of the bottom wall 2.

In this embodiment, the second through hole 351 and the second projection 352 of the second connecting portion 35 are provided on a part of the second rib 301. The second rib 301 has a flattened shape, and the second through hole 351 and the second projection 352 are provided at both ends of the second rib 301 in the longitudinal direction (Z-axis direction in the figure). The portion of the second rib 301 in which the second through hole 351 is provided protrudes further outward from the first side wall 3 than the other portions. The second through hole 351 penetrates a part of the protruding portion of the second rib 301 in the thickness direction (Y-axis direction in the figure). As a result, the second through hole 351 can be fitted with the sixth projection 552 of the sixth connecting portion 55 provided on the second box body 11.

[0040] Furthermore, the portion of the second rib 301 on which the second projection 352 is provided protrudes further outward from the first side wall 3 than the other portions. The second projection 352 protrudes to the rear (negative side in the Y-axis direction in Figure 5) on the protruding portion of the second rib 301. As a result, the second projection 352 can be fitted into the sixth through hole 551 of the sixth connecting portion 55 provided in the second box body 11.

[0041] As described above, the first through hole 341 of the first connecting portion 34 and the second through hole 351 of the second connecting portion 35 correspond to the "first through holes of multiple first connecting portions" as referred to in this disclosure. The first projection 342 of the first connecting portion 34 and the second projection 352 of the second connecting portion 35 correspond to the "first projections of multiple first connecting portions" as referred to in this disclosure.

[0042] The first outer wall surface 30 is provided with a first positioning section 33 for positioning the second box body 11 relative to the first box body 11 (see Figures 6 and 7).

[0080] Furthermore, the portion of the 10th rib 501 on which the sixth projection 552 is provided protrudes further outward from the third side wall 5 than the other portions. The sixth projection 552 protrudes to the rear (negative side in the Y-axis direction in Figure 5) on the protruding portion of the 10th rib 501. As a result, the sixth projection 552 can be fitted into the second through hole 351 of the second connecting portion 35 provided in the fourth box body 11.

[0081] As described above, the fifth through hole 541 of the fifth connecting portion 54 and the sixth through hole 551 of the sixth connecting portion 55 correspond to the "third through holes of the multiple third connecting portions" as referred to in this disclosure. The fifth projection 542 of the fifth connecting portion 54 and the sixth projection 552 of the sixth connecting portion 55 correspond to the "third projections of the multiple third connecting portions" as referred to in this disclosure.

Figure 9 is a bottom view after the connection between the first wiring equipment box 1A and the second wiring equipment box 1B.

[0113] The first box body 11 of the first wiring equipment box 1A and the second box body 11 of the second wiring equipment box 1B are connected via the first outer wall surface 30 of the first side wall 3 of the first box body 11 and the third outer wall surface 50 of the third side wall 5 of the second box body 11.

[0114] More specifically, a first connecting portion 34 provided on the first outer wall surface 30 of the first wiring equipment box 1A is connected to a fifth connecting portion 54 provided on the third outer wall surface 50 of the second wiring equipment box 1B. The first connecting portion 34 includes a first through hole 341 and a first projection 342, and the fifth connecting portion 54 includes a fifth through hole 541 and a fifth projection 542. The first through hole 341 of the first connecting portion 34 of the first wiring equipment box 1A fits into the fifth projection 542 of the fifth connecting portion 54 of the second wiring equipment box 1B, and the first projection 342 of the first connecting portion 34 fits into the fifth through hole 541 of the fifth connecting portion 54.

[0115] Furthermore, a second connecting portion 35 provided on the first outer wall surface 30 of the first wiring equipment box 1A is connected to a sixth connecting portion 55 provided on the third outer wall surface 50 of the second wiring equipment box 1B. The second connecting portion 35 includes a second through hole 351 and a second projection 352, and the sixth connecting portion 55 includes a sixth through hole 551 and a sixth projection 552. The second through hole 351 of the second connecting portion 35 of the first wiring equipment box 1A fits into the sixth projection 552 of the sixth connecting portion 55 of the second wiring equipment box 1B. The second projection 352 of the second connecting portion 35 of the first wiring equipment box 1A fits into the sixth through hole 551 of the sixth connecting portion 55 of the second wiring equipment box 1B.

[0116] Furthermore, the position of the second box body 11 relative to the first box body 11 is positioned by the first positioning part 33 provided on the first outer wall surface 30 of the first wiring equipment box 1A and the third positioning part 53 provided on the third outer wall surface 50 of the second wiring equipment box 1B.

[0117] More specifically, the first positioning portion 33 includes a first protrusion 331 and a first recess 332, and the third positioning portion 53 includes a third protrusion 531 and a third recess 532. The first protrusion 331 of the first positioning portion 33 of the first wiring equipment box 1A is inserted into the third recess 532 of the third positioning portion 53 of the second wiring equipment box 1B. The third protrusion 531 of the third positioning portion 53 of the first wiring equipment box 1A is inserted into the first recess 332 of the first positioning portion 33 of the second wiring equipment box 1B.

[0118] Here, on the first outer wall surface 30, the first protrusion 331 is provided on the third rib 302, and the first recess 332 is provided on the fourth rib 303. The first protrusion 331 and the first recess 332 of the first positioning portion 33 protrude outward from the first side wall 3 (towards the second wiring equipment box 1B in the figure) beyond the protruding portion of the first rib 300 where the first through hole 341 of the first connecting portion 34 is provided. Furthermore, the first protrusion 331 and the first recess 332 of the first positioning portion 33 protrude outward from the first side wall 3 (towards the second wiring equipment box 1B in the figure) beyond the protruding portion of the second rib 301 where the second through hole 351 of the second connecting portion 35 is provided, and beyond the protruding portion of the second rib 301 where the second projection 352 of the second connecting portion 35 is provided.

[0119] Furthermore, on the third outer wall surface 50, the third protrusion 531 is provided on the 11th rib 502, and the third recess 532 is provided on the 12th rib 503. The third protrusion 531 and the third recess 532 of the third positioning portion 53 protrude further outward from the third side wall 5 (towards the first wiring equipment box 1A in the figure) than the protruding portion of the 9th rib 500 where the 5th through hole 541 of the 5th connecting portion 54 is provided. Also, the third protrusion 531 and the third recess 532 of the third positioning portion 53 protrude further outward from the third side wall 5 (towards the first wiring equipment box 1A in the figure) than the protruding portion of the 10th rib 501 where the 6th through hole 551 of the 6th connecting portion 55 is provided, and the protruding portion of the 10th rib 501 where the 6th projection 552 of the 6th connecting portion 55 is provided.

[0120] Therefore, according to the first connection configuration of this embodiment, the position of the second box body 11 relative to the first box body 11 can be positioned by the first positioning unit 33 and the third positioning unit 53 before connecting the first connecting unit 34 and the second connecting unit 35 of the first outer wall surface 30 of the first wiring equipment box 1A with the fifth connecting unit 54 and the sixth connecting unit 55 of the third outer wall surface 50 of the second wiring equipment box 1B.

[0121] Furthermore, when the first box body 11 and the second box body 11 are connected, a sealed space is formed by the first rib 300, second rib 301, third rib 302 and fourth rib 303 of the first outer wall surface 30 and the ninth rib 500, tenth rib 501, eleventh rib 502 and twelfth rib 503 of the third outer wall surface 50. Here, a knockout hole 39 for connecting electrical conduit is formed in the first side wall 3 of the first box body 11, and a knockout hole 59 for connecting electrical conduit is formed in the third side wall 5 of the second box body 11. Since the connection portion between the first box body 11 of the first wiring equipment box 1A and the second box body 11 of the second wiring equipment box 1B is sealed, concrete is less likely to enter the connection portion of the electrical conduit connecting the first wiring equipment 100 of the first wiring equipment box 1A and the second wiring equipment 100 of the second wiring equipment box 1B. This makes construction work easier.

[0122] (2-3) Second Connection Method Next, a second connection method for connecting multiple wiring equipment boxes 1 of this embodiment will be described using Figures 10 to 13.

[0123] Here too, the two connecting wiring equipment boxes 1 have the same structure, and the box bodies of the two wiring equipment boxes 1 also have the same structure. For convenience, the two connecting wiring equipment boxes 1 may be referred to as the first wiring equipment box 1A and the third wiring equipment box 1C below. Also, the box body 11 of the first wiring equipment box 1A may be referred to as the first box body 11, and the box body 11 of the third wiring equipment box 1C may be referred to as the third box body 11.

[0124] Figure 10 is a perspective view showing the first connection configuration (before connection) between the first wiring equipment box 1A and the third wiring equipment box 1C. Figure 11 is a perspective view showing the first connection configuration (after connection) between the first wiring equipment box 1A and the third wiring equipment box 1C. Figure 12 is a plan view after the connection between the first wiring equipment box 1A and the third wiring equipment box 1C. Figure 13 is a bottom view after the connection between the first wiring equipment box 1A and the third wiring equipment box 1C.

[0125] The first box body 11 of the first wiring equipment box 1A and the second box body 11 of the third wiring equipment box 1C are connected via the second outer wall surface 40 of the second side wall 4 of the first wiring equipment box 1A and the fourth outer wall surface 60 of the fourth side wall 6 of the third wiring equipment box 1C.

The third connecting portion 44 includes a third through hole 441 and a third projection 442, and the seventh connecting portion 64 includes a seventh through hole 641 and a seventh projection 642. The third through hole 441 of the third connecting portion 44 fits into the seventh projection 642 of the seventh connecting portion 64, and the third projection 442 of the third connecting portion 44 fits into the seventh through hole 641 of the seventh connecting portion 64.

[0127] Furthermore, a fourth connecting portion 45 provided on the second outer wall surface 40 and an eighth connecting portion 65 provided on the fourth outer wall surface 60 are connected. The fourth connecting portion 45 includes a fourth through hole 451 and a fourth projection 452, and the eighth connecting portion 65 includes an eighth through hole 651 and an eighth projection 652. The fourth through hole 451 of the fourth connecting portion 45 fits into the eighth projection 652 of the eighth connecting portion 65, and the fourth projection 452 of the fourth connecting portion 45 fits into the eighth through hole 651 of the eighth connecting portion 65.

[0128] Furthermore, the position of the third box body 11 relative to the first box body 11 is determined by the second positioning section 43 provided on the second outer wall surface 40 and the fourth positioning section 63 provided on the fourth outer wall surface 60.

[0129] More specifically, the second positioning portion 43 includes a second protrusion 431 and a second recess 432, and the fourth positioning portion 63 includes a fourth protrusion 631 and a fourth recess 632. The second protrusion 431 of the second positioning portion 43 is inserted into the fourth recess 632 of the fourth positioning portion 63, and the fourth protrusion 631 of the fourth positioning portion 63 is inserted into the second recess 432 of the second positioning portion 43.

[0130] Here, on the second outer wall surface 40, the second protrusion 431 is provided on the seventh rib 402, and the second recess 432 is provided on the eighth rib 403. The second protrusion 431 and the second recess 432 of the second positioning portion 43 protrude outward from the second side wall 4 (towards the third wiring equipment box 1C in the figure) beyond the protruding portion of the fifth rib 400 where the second through hole 351 of the second connecting portion 35 is provided. Furthermore, the second protrusion 431 and the second recess 432 of the second positioning portion 43 protrude outward from the first side wall 3 (towards the second wiring equipment box 1B in the figure) beyond the protruding portion of the sixth rib 401 where the fourth through hole 451 of the fourth connecting portion 45 is provided, and beyond the protruding portion of the sixth rib 401 where the fourth projection 452 of the fourth connecting portion 45 is provided.

[0131] Furthermore, on the fourth outer wall surface 60, the fourth protrusion 631 is provided on the 15th rib 602, and the fourth recess 632 is provided on the 16th rib 603. The fourth protrusion 631 and the fourth recess 632 of the fourth positioning portion 63 protrude outward from the fourth side wall 6 (towards the first wiring equipment box 1A in the figure) beyond the protruding portion of the 13th rib 600, where the seventh through hole 641 of the seventh connecting portion 64 is provided.

[0132] Furthermore, the fourth protrusion 631 and the fourth recess 632 of the fourth positioning portion 63 protrude outward from the fourth side wall 6 (towards the first wiring equipment box 1A in the figure) beyond the protruding portion of the 14th rib 601 where the eighth through hole 651 of the eighth connecting portion 65 is provided, and beyond the protruding portion of the 14th rib 601 where the eighth projection 652 of the eighth connecting portion 65 is provided.

[0133] Accordingly, according to the second connection configuration of this embodiment, the position of the third box body 11 relative to the first box body 11 can be positioned by the second positioning unit 43 and the fourth positioning unit 63 before connecting the third and fourth connecting units 44 and 45 of the second outer wall surface 40 with the seventh and eighth connecting units 65 of the fourth outer wall surface 60.

[0134] Furthermore, when the first box body 11 and the third box body 11 are connected, a sealed space is formed by the fifth rib 400, sixth rib 401, seventh rib 402, and eighth rib 403 of the second outer wall surface 40, and the thirteenth rib 600, fourteenth rib 601, fifteenth rib 602, and sixteenth rib 603 of the fourth outer wall surface 60. Here, a knockout hole 49 for connecting electrical conduit is formed in the second side wall 4 of the first box body 11, and a knockout hole 69 for connecting electrical conduit is formed in the fourth side wall 6 of the third box body 11. Since the connection portion between the first box body 11 and the third box body 11 is sealed, concrete is less likely to enter the connection portion of the electrical conduit connecting the first wiring equipment 100 of the first wiring equipment box 1A and the third wiring equipment 100 of the third wiring equipment box 1C. This makes construction work easier.

[0135] (2-4) Installation of Wiring Equipment Next, the installation of the wiring equipment 100 housed in the wiring equipment box 1 of this embodiment will be explained with reference to Figure 14.
