Furthermore, the arrows indicating "D1," "D2," and "D3" in the drawings are merely shown for the purpose of explanation and do not have any physical substance.

[0012] Hereinafter, a distribution board system C1 including a distribution board plate A1 according to the embodiment will be described with reference to FIGS.

[0013] (1) Distribution board system 1, the distribution board system C1 includes a distribution board B1 and a distribution board plate A1. The distribution board B1 is attached to a construction surface 91 of a wall 90 inside a building such as a house. The distribution board plate A1 is disposed between the distribution board B1 and the construction surface 91 of the wall 90.

[0014] (2) Components of the distribution board system (2.1) Distribution board The distribution board B1 includes, for example, a main breaker 71, a plurality of branch breakers 72, a cabinet 70, and an outer cover.

[0015] The cabinet 70 houses a main breaker 71 and a plurality of branch breakers 72. The cabinet 70 is box-shaped (for example, rectangular box-shaped) with an open front. The cabinet 70 is made of, for example, resin. The cabinet 70 is attached to an installation surface 91.

[0016] The outer lid is attached to the cabinet 70 so as to move between a position where it closes the front surface of the cabinet 70 and a position where it opens the front surface of the cabinet 70. The outer lid is, for example, in the shape of a plate (for example, a rectangular plate). The outer lid is made of, for example, resin.

[0017] An opening 73 is provided in the bottom wall of the cabinet 70, through which a plurality of electric wires 80 pass. The plurality of electric wires 80 are connected to the main breaker 71 and the plurality of branch breakers 72, respectively. The plurality of electric wires 80 are electric wires for supplying power to the distribution board B1.

[0018] The main breaker 71 includes a primary terminal 74 and a secondary terminal 75. The primary terminal 74 of the main breaker 71 is electrically connected to an external power source. The secondary terminals 75 of the main breaker 71 are electrically connected to each of the multiple branch breakers 72. The external power source is, for example, a system power source (commercial power source).

[0019] Each of the plurality of branch breakers 72 includes a first connection terminal and a second connection terminal. The first connection terminal is electrically connected to a secondary terminal 75 of the main breaker 71. The second connection terminal is electrically connected to one or more loads. Examples of the loads include lighting fixtures, electrical appliances, hot water supply equipment, electrical outlets, and wiring devices. Examples of the wiring devices include wall switches.

[0020] (2.2) Distribution board plate The distribution board plate A1 includes a plate body 10 and a plurality of holding portions 20 (two in the example of FIG. 1).

[0021] (2.2.1) Plate body The plate body 10 is, for example, plate-shaped (for example, rectangular plate-shaped). The material of the plate body 10 is, for example, metal. The area of ​​the plate body 10 is, for example, the same as the bottom area of ​​the cabinet 70 of the distribution board B1. Note that the area of ​​the plate body 10 is the surface area of ​​the plate body 10 when viewed from the front in the front-rear direction (first direction D1) of the plate body 10. Furthermore, "the area of ​​the plate body 10 is the same as the bottom area of ​​the cabinet 70" does not only mean that the area of ​​the plate body 10 and the bottom area of ​​the cabinet 70 are exactly the same, but also includes, for example, a case where the difference between the area of ​​the plate body 10 and the bottom area of ​​the cabinet 70 (the absolute value of the difference) is equal to or less than a predetermined value.

[0022] The plate body 10 has, for example, a plurality of (two in the example of FIG. 1) insertion holes 11. The plurality of insertion holes 11 include a first insertion hole 12 and a second insertion hole 13.

[0023] An electric wire 80 is inserted through the first insertion hole 12. More specifically, the electric wire 80 that passes through one of the plurality of holding portions 20 (for example, a first holding portion 21 described below) is inserted through the first insertion hole 12. The first insertion hole 12 has, for example, a rectangular shape (for example, a rectangular shape). The first insertion hole 12 is provided along the left-right direction (second direction D2) of the plate body 10. The first insertion hole 12 is also provided at the upper end of the plate body 10 in the up-down direction (third direction D3) and at the center of the plate body 10 in the left-right direction. The vertical dimension of the first insertion hole 12 is, for example, the same as the outer diameter of the electric wire 80. Note that "the vertical dimension of the first insertion hole 12 is the same as the outer diameter of the electric wire 80" does not necessarily mean that the vertical dimension of the first insertion hole 12 and the outer diameter of the electric wire 80 are exactly the same, but also means that, for example, the difference (absolute value of the difference) between the vertical dimension of the first insertion hole 12 and the outer diameter of the electric wire 80 is equal to or less than a predetermined value.

[0024] The second insertion hole 13 is, like the first insertion hole 12, through which the electric wire 80 is inserted. More specifically, the second insertion hole 13 is, for example, rectangular (e.g., oblong). The second insertion hole 13 is provided along the left-right direction of the plate body 10. The second insertion hole 13 is provided at the bottom end of the plate body 10 in the up-down direction and at the center of the plate body 10 in the left-right direction. The vertical dimension of the second insertion hole 13 is, for example, the same as the outer diameter of the electric wire 80. Note that "the vertical dimension of the second insertion hole 13 is the same as the outer diameter of the electric wire 80" does not only mean that the vertical dimension of the second insertion hole 13 and the outer diameter of the electric wire 80 are exactly the same, but also means that, for example, the difference between the vertical dimension of the second insertion hole 13 and the outer diameter of the electric wire 80 (the absolute value of the difference) is equal to or less than a predetermined value.

[0025] The plate body 10 has one mounting hole 14, as shown in Figures 2 and 3, for example. A mounting member is inserted through the mounting hole 14 to mount (more specifically, temporarily fasten) the plate body 10 to the construction surface 91. The mounting member is, for example, a screw. As shown in Figure 3, for example, the mounting hole 14 is provided at the top end of the plate body 10 in the vertical direction and at the center of the plate body 10 in the horizontal direction. Furthermore, the mounting hole 14 is provided at a position on the plate body 10 above the position of the first insertion hole 12.

[0026] The plate body 10 also has, for example, a plurality of (four in the example of FIG. 3 ) fixing holes (first fixing holes) 15. A fixing member for fixing the distribution board B1 (see FIG. 1 ) and the distribution board plate A1 to the installation surface 91 (see FIG. 1 ) is inserted into each of the plurality of first fixing holes 15. The fixing member is, for example, a screw or the like. The plurality of first fixing holes 15 are also provided, for example, at the four corners of the plate body 10. Here, a plurality of second fixing holes (not shown) are provided in the bottom wall of the cabinet 70 shown in FIG. 1 . The fixing members that pass through the plurality of first fixing holes 15 in the plate body 10 are inserted into the plurality of second fixing holes. That is, a plurality of second fixing holes are provided in the bottom wall of the cabinet 70 at positions that face the plurality of first fixing holes 15 in the plate body 10 when the bottom wall of the cabinet 70 and the plate body 10 overlap in the front-to-rear direction (first direction D1) of the distribution board B1.

[0027] As shown in Fig. 4, the plate body 10 closes the opening hole 92 of the wall 90. The opening hole 92 is, for example, rectangular (e.g., oblong). The opening area of ​​the opening hole 92 is smaller than the area of ​​the plate body 10. Note that "the plate body 10 closes the opening hole 92" means that the outer peripheral edge 16 of the plate body 10 and the inner peripheral edge 94 of the opening hole 92 overlap with each other.

[0028] 5, the plate body 10 is disposed between the distribution board B1 and the installation surface 91. More specifically, when the distribution board B1 is attached to the installation surface 91, the plate body 10 is sandwiched between the distribution board B1 and the installation surface 91. Note that FIG. 5 is a cross-sectional view taken along line XX in FIG. 2.

[0029] (2.2.2) Holding part The plurality of holding portions 20 include a first holding portion 21 and a second holding portion 22, as shown in FIG.

[0030] The first holding portion 21 passes the electric wire 80 through and holds the electric wire 80. The first holding portion 21 holds the electric wire 80 so as to be in contact with the outer peripheral surface of the electric wire 80. As shown in FIGS. 4 and 5, the first holding portion 21 is, for example, columnar (for example, rectangular parallelepiped). The first holding portion 21 is, for example, configured in a sponge-like shape. The first holding portion 21 is, for example, a sponge packing. Note that "sponge-like" means, for example, a structure including many voids and having flexibility.

[0031] The first holding portion 21 has a slit 23 through which the electric wire 80 passes. For example, a plurality of electric wires 80 pass through the slit 23. The slit 23 is a rectangular (e.g., oblong) opening hole, as shown in FIG. 4, for example. The slit 23 is provided along the left-right direction (second direction D2) of the first holding portion 21. The slit 23 is also disposed in the center of the first holding portion 21 in the left-right direction and the up-down direction (third direction D3).

[0032] The left-right dimension of the slit 23 is smaller than the left-right dimension of the first holding portion 21. The up-down dimension of the slit 23 is smaller than the up-down dimension of the first insertion hole 12 of the plate body 10. For example, the up-down dimension of the slit 23 is 1 / 10 of the up-down dimension of the first insertion hole 12 of the plate body 10.

[0033] Similar to the first holding portion 21, the second holding portion 22 passes the electric wire 80 through and holds the electric wire 80. The second holding portion 22 holds the electric wire 80 so as to come into contact with the outer peripheral surface of the electric wire 80. As shown in FIGS. 4 and 5, the second holding portion 22 is, for example, columnar (for example, rectangular parallelepiped). The second holding portion 22 is, for example, sponge-like. The second holding portion 22 is, for example, sponge packing.

[0034] The second holding portion 22 has a slit 24 through which the electric wire 80 passes. For example, a plurality of electric wires 80 pass through the slit 24. The slit 24 is a rectangular (e.g., oblong) opening hole, as shown in FIG. 4, for example. The slit 24 is provided along the left-right direction (second direction D2) of the second holding portion 22. The slit 24 is also disposed in the center of the second holding portion 22 in the left-right direction and the up-down direction (third direction D3). Note that FIG. 1 illustrates a case in which only one electric wire 80 passes through the slit 24 of the second holding portion 22, but does not illustrate a case in which other electric wires 80 pass through the slit 24 of the second holding portion 22.

[0035] The left-right dimension of the slit 24 is smaller than the left-right dimension of the second holding portion 22. The up-down dimension of the slit 24 is smaller than the up-down dimension of the second insertion hole 13 of the plate body 10. For example, the up-down dimension of the slit 24 is 1 / 10 of the up-down dimension of the second insertion hole 13 of the plate body 10.

[0036] As shown in Fig. 5, the first retaining portion 21 is disposed inside the inner peripheral surface 93 of the opening hole 92 of the construction surface 91, and is attached to one surface (rear surface) 17 of the plate body 10 so as to close the first insertion hole 12 of the plate body 10. More specifically, as shown in Fig. 3, the first retaining portion 21 is attached to the plate body 10 so as to close the first insertion hole 12 of the plate body 10 and so that the slit 23 of the first retaining portion 21 is exposed from the first insertion hole 12. The first retaining portion 21 is attached to the plate body 10 using, for example, tape (for example, double-sided tape) or the like.

[0037] Similar to the first retaining portion 21, the second retaining portion 22 is disposed inside the inner peripheral surface 93 of the opening hole 92 of the construction surface 91, as shown in Fig. 5, and is attached to one surface 17 of the plate body 10 so as to block the second insertion hole 13 of the plate body 10. More specifically, as shown in Fig. 3, the second retaining portion 22 is attached to the plate body 10 so as to block the second insertion hole 13 of the plate body 10 and so that the slit 24 of the second retaining portion 22 is exposed from the second insertion hole 13. The second retaining portion 22 is attached to the plate body 10 using, for example, tape (for example, double-sided tape) or the like.

[0038] (3) Installation of distribution board system 1 to the construction surface 91. The following description will be given assuming that the distribution board B1 has a main breaker 71 and a plurality of branch breakers 72 mounted in a cabinet 70. The following description will also assume that a plurality of electric wires 80 are drawn out from openings 92 in the construction surface 91.

[0039] First, the worker inserts multiple electric wires 80 into the slits 23 of the first holding portion 21 of the distribution board plate A1 and the slits 24 of the second holding portion 22, and then pulls the multiple electric wires 80 out of the first insertion hole 12 and the second insertion hole 13 of the plate main body 10.

[0040] Next, the worker electrically connects the multiple electric wires 80 drawn out from the first insertion hole 12 and the second insertion hole 13 of the plate body 10 to the main breaker 71 and the multiple branch breakers 72 of the distribution board B1, respectively.

[0041] Then, the worker blocks the opening hole 92 of the construction surface 91 with the plate body 10, and while pressing the plate body 10 against the construction surface 91, inserts the mounting member into the mounting hole 14 of the plate body 10 to temporarily secure the plate body 10 to the construction surface 91.

[0042] In addition, with the outer cover of the distribution board B1 open, the worker aligns the multiple second fixing holes in the bottom wall of the cabinet 70 with the multiple first fixing holes 15 of the plate body 10, and then inserts multiple fixing members into the multiple second fixing holes and the multiple first fixing holes 15, respectively, to fix the cabinet 70 and plate body 10 of the distribution board B1 to the construction surface 91.

[0043] Finally, the worker closes the outer cover of the distribution board B1, thereby completing the installation of the distribution board system C1.

[0044] (4) Effects The distribution board plate A1 includes a plate body 10 and a plurality of holding portions 20. Each holding portion 20 passes an electric wire 80 through and holds the electric wire 80. The plate body 10 closes an opening 92 in an installation surface 91 and is disposed between the distribution board B1 and the installation surface 91. This allows the distribution board plate A1 to improve the airtightness and fire resistance of buildings such as homes.

[0045] Furthermore, with the spread of ZEH (Net Zero Energy House), there is a growing demand for improved airtightness in modern homes. One method for improving the airtightness of a home is to fill the openings 92 in the construction surface 91 with a urethane material, for example. However, this method makes it difficult to add a circuit breaker (e.g., branch breaker 72) to the distribution board B1. On the other hand, in the distribution board plate A1, a plate body 10 that is detachable from the construction surface 91 covers the openings 92 in the construction surface 91, and the plate body 10 is disposed between the distribution board B1 and the construction surface 91. Therefore, the distribution board plate A1 can improve airtightness and fire resistance, and can also add a circuit breaker to the distribution board B1.

[0046] The plate body 10 is sandwiched between the distribution board B1 and the installation surface 91. The multiple holding portions 20 are arranged inside the inner peripheral surface 93 of the opening hole 92 of the installation surface 91, and are attached to one surface 17 of the plate body 10 so as to close each of the multiple insertion holes 11 of the plate body 10. This makes it possible to further improve the airtightness of the distribution board plate A1.

[0047] 5 , in the distribution board plate A1, the plurality of retaining portions 20 are disposed inside the inner peripheral surface 93 of the opening hole 92 in the construction surface 91, and are attached to one surface 17 of the plate body 10 so as to block the plurality of insertion holes 11 of the plate body 10, respectively. As a result, in the distribution board plate A1, the gap between the distribution board B1 and the distribution board plate A1 can be made smaller than when, for example, the plurality of retaining portions 20 are fitted into the plurality of insertion holes 11 of the plate body 10, respectively. Therefore, in the distribution board plate A1, the distribution board B1 and the distribution board plate A1 can be more easily attached together to the construction surface 91 than when, for example, the plurality of retaining portions 20 are fitted into the plurality of insertion holes 11 of the plate body 10, respectively. In other words, in the distribution board plate A1, it is possible to improve the workability of attaching the distribution board B1 and the distribution board plate A1 (distribution board system C1) to the construction surface 91.

[0048] Each holding portion 20 is formed in a sponge-like shape and holds the electric wire 80 so as to come into contact with the outer peripheral surface of the electric wire 80. This makes it possible to further improve the airtightness of the distribution board plate A1.

[0049] Furthermore, each holding portion 20 has a slit 23 through which the electric wire 80 passes. This makes it easier to pass the electric wire 80 through each holding portion 20 in the distribution board plate A1. Therefore, the distribution board plate A1 can further improve the workability of attaching the distribution board system C1 to the installation surface 91.

[0050] The material of the plate body 10 contains metal, which makes it possible to further improve the fire resistance of the distribution board plate A1.

[0051] The plate body 10 has mounting holes 14. This allows a worker to temporarily fasten the distribution board plate A1 to the construction surface 91 when, for example, attaching the distribution board system C1 to the construction surface 91. Therefore, with the distribution board plate A1, a worker can attach the distribution board system C1 to the construction surface 91 by himself, which further improves the workability of attaching the distribution board system C1 to the construction surface 91.

[0052] The distribution board system C1 includes a distribution board plate A1 and a distribution board B1. With this, the distribution board system C1 can improve the airtightness and fire resistance of a building such as a house.

[0053] The plate body 10 has a plurality of fixing holes 15. This allows the distribution board B1 and the distribution board plate A1 to be fixed together (fastened together) to the construction surface 91 in the distribution board system C1, thereby further improving the workability of attaching the distribution board system C1 to the construction surface 91.

[0054] (5) Variations The material of the plate body 10 is not limited to metal, but may be a fire-resistant resin or the like. The plate body 10 has only one mounting hole 14, but may have multiple mounting holes 14. The plate body 10 has multiple insertion holes 11, but may have only one insertion hole 11.

[0055] The first holding portion 21 and the second holding portion 22 are not limited to sponge packing, and may be, for example, airtight waterproof tape, etc. Furthermore, the first holding portion 21 and the second holding portion 22 are not limited to being sponge-like, and may be made of, for example, a rigid resin.

[0056] The first holding portion 21 has slits 23 through which the multiple electric wires 80 pass, but may have, for example, multiple holes (first holes) through which each of the multiple electric wires 80 passes. The second holding portion 22 has slits 24 through which the multiple electric wires 80 pass, but may have, for example, multiple holes (second holes) through which each of the multiple electric wires 80 passes. In short, the slits 23 and slits 24 are not limited to rectangular openings through which the multiple electric wires 80 pass.

[0057] The first holding portion 21 holds the electric wire 80 so as to be in contact with the outer peripheral surface of the electric wire 80, but may hold the electric wire 80 so as to press against the outer peripheral surface of the electric wire 80, for example. In this case, the vertical dimension of the slit 23 is, for example, less than 1 / 10 of the vertical dimension of the first insertion hole 12 of the plate body 10. The second holding portion 22 holds the electric wire 80 so as to be in contact with the outer peripheral surface of the electric wire 80, but may hold the electric wire 80 so as to press against the outer peripheral surface of the electric wire 80, for example. In this case, the vertical dimension of the slit 24 is, for example, less than 1 / 10 of the vertical dimension of the second insertion hole 13 of the plate body 10.

[0058] The distribution board plate A1 has a plurality of holding portions 20, but may have only one holding portion 20.

[0059] The distribution board B1 includes a main breaker 71, a plurality of branch breakers 72, a cabinet 70, and an outer cover, but may further include, for example, a measuring device or a communication device. That is, the distribution board B1 only needs to include at least the main breaker 71, a plurality of branch breakers 72, a cabinet 70, and an outer cover. Furthermore, the distribution board B1 is not limited to being attached to the construction surface 91 of a wall 90 inside a residential building, and may also be attached to the construction surface of a wall inside a non-residential building, for example.
