DETAILED DESCRIPTION OF THE INVENTION
[0009] The distribution board 1 according to the embodiment will be described below with reference to the drawings. The drawings referred to in the following embodiments are schematic diagrams, and the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensions, and the size ratios and thickness ratios between the components do not necessarily reflect the actual dimensional ratios.
[0010] (1) Overview First, an overview of a distribution board 1 according to an embodiment will be described with reference to FIGS. 1 to 6. FIG.
[0011] The distribution board 1 according to the embodiment is, for example, a distribution board applied to a facility F1 (see FIGS. 2 and 3 ) and is attached to an installation surface W1 of the facility F1. The facility F1 is, for example, a residential facility such as a detached house or each dwelling unit in an apartment building. Note that the facility F1 is not limited to a residential facility, and may be, for example, a non-residential facility such as a factory, a store, an office building, a commercial building, a hospital, or a school.
[0012] As shown in FIGS. 1 to 6, the distribution board 1 includes a main body 2, a cover 3, and a hinge 4.
[0013] As shown in FIG. 3, the main body 2 accommodates a breaker 5 therein.
[0014] The lid body 3 has a rectangular plate-shaped flat portion 30 and a side portion (first side portion) 31 that protrudes from one end edge (first end edge) 301 that forms the outer periphery of the flat portion 30 in a direction that intersects with the flat portion 30.
[0015] The hinge 4 connects the first side surface portion 31 and the main body portion 2 in a state in which the cover 3 is movable between a closed position where it covers the breaker 5 and an open position where it opens the breaker 5.
[0016] The first side surface portion 31 protrudes from the first end edge 301 in a direction approaching the main body portion 2 when the cover 3 is in the closed position.
[0017] According to the above configuration, by providing the first side surface portion 31, it is possible to prevent foreign matter from entering the inside of the distribution board 1.
[0018] (2) Composition Next, the configuration of a distribution board 1 according to an embodiment will be described with reference to Figures 1 to 6. As described above, the distribution board 1 is applied to a facility F1, such as each dwelling unit of a detached house or an apartment building, and is attached to an installation surface W1 of the facility F1. The installation surface W1 is, for example, a wall surface of the facility F1.
[0019] In the following description, the top, bottom, left, and right directions are used as references when viewing the distribution board 1 attached to the installation surface W1 from the front. Specifically, the depth direction when viewing the distribution board 1 attached to the installation surface W1 from the front is defined as the front-to-back direction, and the front of the distribution board 1 faces forward. In the drawings, the X-axis direction is defined as the front-to-back direction, the Y-axis direction is defined as the left-to-right direction, and the Z-axis direction is defined as the up-to-down direction. Furthermore, the positive direction of the X-axis direction is defined as the front, the positive direction of the Y-axis direction is defined as the right, and the positive direction of the Z-axis direction is defined as the up. However, these directions are merely examples and are not intended to limit the directions in which the distribution board 1 may be used. In addition, the arrows indicating the directions in the drawings are merely shown for explanatory purposes and do not have any physical substance.
[0020] The distribution board 1 includes a main body 2, a cover 3, a plurality of hinges 4 (two in the illustrated example), and breakers 5 (a main breaker 51 and a plurality of branch breakers 52). Each of the components included in the distribution board 1 will be described in detail below.
[0021] (2.1) Main body The main body 2 has a base portion 21, a cover portion 22, and a plurality of (two in the illustrated example) plate covers 23 (see FIG. 3).
[0022] The base portion 21 is made of a synthetic resin such as ABS (Acrylonitrile Butadiene Styrene) resin. The base portion 21 is formed in the shape of a rectangular box with one side open. When the distribution board 1 is attached to the installation surface W1, the base portion 21 opens forward. When viewed from the front-to-rear direction in a plan view, the longitudinal direction of the base portion 21 is aligned with the left-right direction and the lateral direction is aligned with the up-down direction.
[0023] The base portion 21 has a recessed accommodation portion (not shown) recessed toward the rear. The recessed accommodation portion is a space for accommodating the main breaker 51 and the plurality of branch breakers 52.
[0024] The cover portion 22 is made of a synthetic resin such as ABS resin. The cover portion 22 is formed in the shape of a rectangular box with one side open. When the distribution board 1 is attached to the installation surface W1, the cover portion 22 is open at the rear. When viewed from above in the front-to-rear direction, the cover portion 22 is slightly larger than the base portion 21. The cover portion 22 is assembled to the base portion 21 from the front. When assembled to the base portion 21, the longitudinal direction of the cover portion 22 is aligned with the left-right direction and the lateral direction is aligned with the up-down direction.
[0025] 2 and 3, the distribution board 1 is attached to the installation surface W1 with the upper end surface 221 of the cover portion 22 adjacent to the ceiling C1. Also, in this embodiment, the distribution board 1 is attached to the installation surface W1 with the right end surface 222 of the cover portion 22 adjacent to another wall surface W2 that is perpendicular to the installation surface W1 and the ceiling C1.
[0026] 3, the cover portion 22 has a first opening A1 and a plurality of second openings A2. The first opening A1 is formed in a rectangular shape when viewed from above in the front-rear direction.
[0027] A front surface (functional surface) 510 of the main breaker 51 is exposed forward through the first opening A1. An operating lever 511 for turning on or off the contacts built into the main breaker 51 is provided on the functional surface 510 of the main breaker 51.
[0028] Each of the second openings A2 is formed in a strip shape that is elongated in the left-right direction when viewed from the front-to-back direction. A front surface (functional surface) 520 of each branch breaker 52 is exposed to the front through a corresponding one of the second openings A2. An operating lever 521 is provided on the functional surface 520 of each branch breaker 52 to turn on or off contacts built into each branch breaker 52.
[0029] That is, the main body 2 accommodates the main breaker 51 and the plurality of branch breakers 52 with the functional surface 510 of the main breaker 51 and the functional surface 520 of each of the plurality of branch breakers 52 exposed.
[0030] The first opening A1 is provided at a position closer to the left of the cover portion 22 in a plan view from the front-rear direction. The multiple second openings A2 are provided at positions closer to the right of the cover portion 22 in a plan view from the front-rear direction. The multiple second openings A2 are also provided at positions closer to the right of the cover portion 22 at intervals in the up-down direction.
[0031] 4, the cover portion 22 further has a plurality of recesses 223 (two in the illustrated example). The two recesses 223 are provided on both sides in the left-right direction above the cover portion 22. Each recess 223 is recessed toward the rear. Each recess 223 accommodates at least a portion of each hinge 4 (second mounting portion 42, described later). This allows each hinge 4 to be efficiently accommodated in the main body portion 2.
[0032] Each recess 223 is covered by a plate cover 23 (see FIG. 3 ) with the second mounting portion 42 of each hinge 4 housed therein. The plate cover 23 is a plate-like member formed to have substantially the same shape as the recess 223 when viewed from the front. Notches 231 are provided at both ends in the left-right direction of the plate cover 23. The connection piece 43 of the left hinge 4 protrudes forward from the notch 231 at the left end of the plate cover 23 covering the left recess 223, and the connection piece 43 of the right hinge 4 protrudes forward from the notch 231 at the right end of the plate cover 23 covering the right recess 223. This makes it possible to prevent foreign matter such as dust and moisture from entering each recess 223.
[0033] (2.2) Lid The lid body 3, like the base part 21 and the cover part 22, is formed of a synthetic resin such as ABS resin.
[0034] The cover 3 is formed in the shape of a flat rectangular box with one side open. When the cover 3 is in the closed position covering the main breaker 51 and the plurality of branch breakers 52, the cover 3 is open to the rear.
[0035] The cover 3 has a flat surface portion 30 and a first side surface portion 31 to a fourth side surface portion 34 protruding from the flat surface portion 30. In this embodiment, the flat surface portion 30 and the first side surface portion 31 to the fourth side surface portion 34 are integrally formed.
[0036] The flat portion 30 is formed in a quadrangular plate shape (rectangular plate shape in this embodiment). When the flat portion 30 is viewed from the front, as shown in Fig. 2, four sides, namely a first end side 301 to a fourth end side 304, form the outer periphery of the flat portion 30. Here, the first end side 301 and the third end side 303 are end sides in the longitudinal direction of the flat portion 30 and face each other. Furthermore, the second end side 302 and the fourth end side 304 are end sides in the lateral direction of the flat portion 30 and face each other.
[0037] The first to fourth side surface portions 31 to 34 are each formed in a rectangular plate shape. The first to fourth side surface portions 31 to 34 protrude from the first end side 301 to the fourth end side 304, respectively, in a direction intersecting with the flat surface portion 30. In this embodiment, the first to fourth side surface portions 31 to 34 protrude in a direction perpendicular to the flat surface portion 30. Furthermore, in this embodiment, the first to fourth side surface portions 31 to 34 protrude in the same direction perpendicular to the flat surface portion 30. In other words, the first side surface portion 31 and the third side surface portion 33 face each other, and the second side surface portion 32 and the fourth side surface portion 34 face each other.
[0038] As shown in Fig. 4, the first side surface portion 31 is connected to the main body portion 2 (cover portion 22) by two hinges 4. When the first side surface portion 31 and the main body portion 2 are connected by the two hinges 4, the cover body 3 is movable between a closed position (see Figs. 2 and 5) that covers the main breaker 51 and the plurality of branch breakers 52 and an open position (see Figs. 3 and 6) that opens the main breaker 51 and the plurality of branch breakers 52.
[0039] In this embodiment, when the cover 3 is in the closed position, the first side surface portion 31 to the fourth side surface portion 34 protrude from the first end edge 301 to the fourth end edge 304 in a direction (rearward) toward the cover unit 22. At this time, the rear ends of the first side surface portion 31 to the fourth side surface portion 34 face the cover unit 22 with a small gap therebetween. When the cover 3 is in the closed position, the first side surface portion 31 is on the upper side and the third side surface portion 33 is on the lower side. That is, as shown in FIG. 5 , when the cover 3 is in the closed position, the first side surface portion 31 is on the upper side. In this way, by providing the first side surface portion 31, it is possible to prevent foreign matter such as dust and moisture from entering the interior of the distribution board 1 when the cover 3 is in the closed position. In particular, it is possible to prevent foreign matter from entering the interior of the distribution board 1 from above.
[0040] Furthermore, as shown in FIG. 2 , when the lid body 3 is in the closed position, the lid body 3 is located inside the main body 2 in a plan view from the normal direction of the flat surface portion 30. In this embodiment, when the lid body 3 is in the closed position, the normal direction (thickness direction) of the flat surface portion 30 is the front-rear direction. In other words, when the lid body 3 is in the closed position, the lid body 3 is formed so as to be smaller than the main body 2 in a plan view from the front-rear direction. This makes it easier for the lid body 3 to move between the closed position and the open position, and the trajectory of the lid body 3 to be located inside the main body 2 in a plan view from the front-rear direction. Therefore, when the lid body 3 is moved between the closed position and the open position, it is possible to reduce the possibility that the lid body 3 will come into contact with an object (such as the ceiling C1 or the wall W2 in this embodiment) located outside the main body 2 in a plan view.
[0041] 6, the cover 3 is in an open state when rotated approximately 90° counterclockwise from the closed position in a side view from the left. In other words, when the cover 3 is in the open position, the first side surface portion 31 is on the rear side and the third side surface portion 33 is on the front side.
[0042] (2.3) Hinge As described above, the two hinges 4 connect the first side surface portion 31 and the main body portion 2 in a state in which the cover 3 is movable between the closed position and the open position. In this embodiment, each hinge 4 is a torque hinge. That is, each hinge 4 connects the first side surface portion 31 and the main body portion 2 so that the cover 3 moves when a torque equal to or greater than a predetermined torque is applied to the cover 3 by an operation by a user or the like. In other words, each hinge 4 connects the first side surface portion 31 and the main body portion 2 so that the cover 3 does not move when a torque equal to or greater than the predetermined torque is not applied to the cover 3.
[0043] 4 to 6, each hinge 4 has a first attachment portion 41, a second attachment portion 42, and a connection piece 43. Each hinge 4 further has a shaft 44.
[0044] The first mounting portion 41 is formed in the shape of a flat rectangular plate. The first mounting portion 41 is housed between a protruding piece 311 that protrudes from an inner wall surface 310 of the first side surface portion 31 toward the third side surface portion 33 and the inner wall surface 300 of the flat surface portion 30. More specifically, the first mounting portion 41 is housed so that the longitudinal direction of the first mounting portion 41 is aligned with the longitudinal direction of the flat surface portion 30 and the lateral direction of the first mounting portion 41 is aligned with the lateral direction of the flat surface portion 30.
[0045] Here, the protruding piece 311 and the first side surface portion 31 are integrally formed. The first mounting portion 41 is fixed to the protruding piece 311 with a fastener such as a screw. Specifically, a screw is screwed into a screw hole provided in the first mounting portion 41 and a through hole provided in the protruding piece 311. In this manner, the first mounting portion 41 is attached to the inner wall surface 310 of the first side surface portion 31 via the protruding piece 311. Note that the first mounting portion 41 may also be attached directly to the inner wall surface 310. Alternatively, the first mounting portion 41 may also be attached to the inner wall surface 300 of the flat portion 30.
[0046] The second mounting portion 42 is formed in a rectangular plate shape. The second mounting portion 42 is inserted into a substantially L-shaped insertion piece 224 provided on the bottom surface of the recess 223. With the second mounting portion 42 inserted into the insertion piece 224, it is fixed to the bottom surface of the recess 223 with a fastener such as a screw. Specifically, screws are screwed into a screw hole or through hole provided in the second mounting portion 42 and a screw hole provided in the bottom surface of the recess 223. In this way, the second mounting portion 42 is attached to the cover portion 22 so that the thickness direction is along the front-rear direction.
[0047] The connecting piece 43 is formed in a plate shape. The connecting piece 43 has a base piece 431 and a support piece 432. The base piece 431 and the support piece 432 are mechanically connected. In this embodiment, the base piece 431 and the support piece 432 are formed integrally. Alternatively, the base piece 431 and the support piece 432 may be formed separately and fixed to each other with fasteners such as screws.
[0048] The base piece 431 protrudes forward from the left-right end edge of the second mounting portion 42. More specifically, the base piece 431 of the left hinge 4 protrudes forward from the left end edge of the second mounting portion 42 of the left hinge 4. Furthermore, the base piece 431 of the right hinge 4 protrudes forward from the right end edge of the second mounting portion 42 of the right hinge 4.
[0049] The front end of the base piece 431 is located forward of the cover portion 22. When viewed from the left and right, the base piece 431 is formed in a substantially rectangular shape with a front lower portion cut out.
[0050] The support piece 432 protrudes upward from the front upper portion of the base piece 431. As shown in Figures 5 and 6, the support piece 432 and the cover part 22 face each other in the front-rear direction with a gap G1 therebetween.
[0051] Here, the base piece 431 is mechanically connected to the second mounting portion 42. In this embodiment, the base piece 431 is formed integrally with the second mounting portion 42. Note that the base piece 431 and the second mounting portion 42 may be formed separately and fixed to each other with a fastener such as a screw. Furthermore, the support piece 432 rotatably supports the first mounting portion 41 at its upper end. In other words, the connection piece 43 connects the first mounting portion 41 and the second mounting portion 42.
[0052] The support structure of the first attachment portion 41 by the support piece 432 will be described in detail below.
[0053] The shaft 44 is inserted through the first mounting portion 41 so that the extension direction of the shaft 44 is along the longitudinal direction of the first mounting portion 41. In addition, an end of the shaft 44 protrudes from the left-right end faces of the first mounting portion 41. More specifically, the end of the shaft 44 protrudes from the left end face of the first mounting portion 41 of the left hinge 4. In addition, the end of the shaft 44 protrudes from the right end face of the first mounting portion 41 of the right hinge 4.
[0054] The end of the shaft 44 protruding from the first mounting portion 41 is fixed to the upper end of the support piece 432. This allows the first mounting portion 41 to rotate around the shaft 44 relative to the connecting piece 43. In other words, the shaft 44 is the rotation axis of the first mounting portion 41 relative to the connecting piece 43. As described above, the first mounting portion 41 is attached to the first side surface portion 31 of the cover 3, and the second mounting portion 42 formed integrally with the connecting piece 43 is attached to the main body 2, so that the cover 3 can rotate around the shaft 44 relative to the main body 2. In this way, each hinge 4 connects the first side surface portion 31 and the main body 2 while the cover 3 is movable between the closed position and the open position.
[0055] 5 and 6, the shaft 44, which is the rotation axis for the connecting piece 43 of the first attachment portion 41, is provided within a predetermined area AR1 around an edge (connecting edge) E1 at which the inner wall surface 310 of the first side surface portion 31 and the inner wall surface 300 of the flat surface portion 30 connect. As an example, the predetermined area AR1 is a square area with the connecting edge E1 as one corner when viewed from the left. Furthermore, when viewed from the left, of the first to fourth edges that form the periphery of the predetermined area AR1, the first edge is a line segment that follows the inner wall surface 310, and the second edge that is perpendicular to the first edge is a line segment that follows the inner wall surface 300. Furthermore, the length of one side of the predetermined area AR1 is half the length of the short side of the inner wall surface 310 (the front-to-rear direction when the cover 3 is in the closed position).
[0056] As a result, when the lid body 3 is rotated relative to the main body 2 around the shaft 44, the rotational orbit of the lid body 3 is more likely to be located below the upper end surface 221 of the main body 2 (cover part 22). Therefore, when the lid body 3 is rotated relative to the main body 2 around the shaft 44, the lid body 3 is less likely to come into contact with an object placed above the upper end surface 221, and therefore the distribution board 1 can be attached to the installation surface W1 with the upper end surface 221 close to the ceiling C1, as shown in FIGS. 2 and 3 .
[0057] Furthermore, when the shaft 44 is provided within the predetermined area AR1, when the cover 3 is in the closed position, the distance between the center point of the shaft 44 and the rear end of the first side surface portion 31 in a side view from the left is shorter than the distance in the front-to-rear direction between the shaft 44 and the cover portion 22. This reduces the possibility that the first side surface portion 31 will come into contact with the cover portion 22 when the cover 3 is rotated relative to the main body 2 around the shaft 44.
[0058] (3) Opening and closing of the lid Next, the movement (opening and closing) of the cover 3 between the closed position and the open position will be described with reference to Figures 5 and 6. Figure 5 is a side view (partial cross-sectional view) of the distribution board 1 with the cover 3 in the closed position. Figure 6 is a side view (partial cross-sectional view) of the distribution board 1 with the cover 3 in the open position.
[0059] 5, when the lid body 3 is in the closed position, the lid body 3 is located below the upper end surface 221 of the cover part 22 of the main body part 2. Furthermore, when the lid body 3 is in the closed position, the first side surface part 31 of the lid body 3 is aligned in the front-to-rear direction, and the first side surface part 31 faces the upper end part of the support piece 432 of each hinge 4 in the up-down direction.
[0060] As described above, the support piece 432 and the cover portion 22 face each other in the front-rear direction via the gap G1. The gap G1 functions as an escape groove into which the first side surface portion 31 is inserted when the lid body 3 is rotated counterclockwise around the shaft 44 in a side view from the left. This makes it easier to rotate the lid body 3 while maintaining a state in which the lid body 3 is positioned below the upper end surface 221. In other words, by allowing the first side surface portion 31 to escape into the gap G1, the trajectory of the lid body 3 can be set to a trajectory in which the lid body 3 does not come into contact with an object positioned above the upper end surface 221.
[0061] When the lid 3 is rotated approximately 90° counterclockwise from the closed position in a side view from the left, the lid 3 is in the open position. When the lid 3 is in the open position, at least a portion of the first side surface portion 31 is inserted into the gap G1. When the lid 3 is in the open position, as shown in FIGS. 3 and 6, the lid 3 is positioned below the upper end surface 221. The vertical length of the gap G1, i.e., the vertical length of the support piece 432, is set to a length such that the tip of the first side surface portion 31 does not contact the base piece 431 when the lid 3 is in the open position.
[0062] Here, if a force is applied that tries to rotate the lid 3 further counterclockwise from the open position, the support piece 432 comes into contact with the first side surface portion 31, thereby restricting the rotation of the lid 3. This further reduces the possibility that a part of the lid 3 will come into contact with the ceiling C1 or the like that is above the upper end surface 221.
[0063] (4) Variations The above-described embodiment is merely one of various embodiments of the present disclosure. The above-described embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. Modifications of the above-described embodiment are listed below. The modifications described below can be applied in appropriate combinations.
[0064] In the above-described embodiment, the distribution board 1 is attached to the installation surface W1 so that the first side surface portion 31 is located on the upper side when the cover 3 is in the closed position. However, the distribution board 1 may be attached to the installation surface W1 so that the first side surface portion 31 is located on the left side, right side, or lower side when the cover 3 is in the closed position.
[0065] In the above-described embodiment, the distribution board 1 includes two hinges 4, but may include one hinge 4, or may include three or more hinges 4.
[0066] (5) Summary As described above, the distribution board (1) of the first embodiment comprises a main body (2) that houses a breaker (5), a rectangular plate-shaped flat portion (30), a cover body (3) having a side portion (31) that protrudes from one end edge (301) that forms the outer periphery of the flat portion (30) in a direction that intersects with the flat portion (30), and a hinge (4) that connects the side portion (31) to the main body (2) in a state in which the cover body (3) is movable between a closed position in which it covers the breaker (5) and an open position in which it opens the breaker (5). When the cover body (3) is in the closed position, the side portion (31) protrudes from the end edge (301) in a direction that approaches the main body (2).
[0067] According to this aspect, it is possible to prevent foreign matter from entering the inside of the distribution board (1).

[0069] According to this aspect, it is possible to prevent foreign matter from entering the inside of the distribution board (1) from above.
[0070] In the distribution board (1) of the third aspect, in the first or second aspect, the side surface portion (31) protrudes from the end side (301) in a direction perpendicular to the flat surface portion (30).
[0071] According to this aspect, it is possible to further prevent foreign matter from entering the inside of the distribution board (1).
[0072] In the distribution board (1) of the fourth aspect, in any of the first to third aspects, when the cover body (3) is in the closed position, the cover body (3) is located inside the main body portion (2) in a plan view from the normal direction of the flat portion (30).
[0073] According to this aspect, when the lid body (3) is moved between the closed position and the open position, the trajectory of the lid body (3) is easily kept inside the main body part (2) in a plan view from the normal direction of the flat part (30). This reduces the possibility that the lid body (3) will come into contact with an object placed outside the main body part (2) in a plan view when the lid body (3) is moved between the closed position and the open position.
[0074] In the distribution board (1) of the fifth aspect, in any of the first to fourth aspects, the hinge (4) has a first mounting portion (41) attached to the side surface portion (31), a second mounting portion (42) attached to the main body portion (2), and a connecting piece (43) connecting the first mounting portion (41) and the second mounting portion (42). The connecting piece (43) has a first piece (432) that rotatably supports the first mounting portion (41) and a second piece (431) that is mechanically connected to the second mounting portion (42).
[0075] According to this embodiment, the side portion (31) and the main body portion (2) can be connected together while the cover (3) is movable between the closed position and the open position.
[0076] In the distribution board (1) of the sixth aspect, the first piece (432) and the main body (2) face each other via a gap (G1) in the fifth aspect. When the cover (3) is in the open position, at least a part of the side surface portion (31) is inserted into the gap (G1).
[0077] According to this embodiment, by allowing the side portion (31) to escape into the gap (G1), the trajectory of the lid body (3) can be set to an trajectory that prevents the lid body (3) from coming into contact with an object placed above the upper end surface (221) of the main body portion (2).
[0078] In the seventh aspect of the distribution board (1), in the fifth or sixth aspect, the rotation axis (44) for the connection piece (43) of the first mounting portion (41) is provided within a predetermined area (AR1) around the edge (E1) where the first inner wall surface (310) of the side portion (31) and the second inner wall surface (300) of the flat portion (30) are connected.
[0079] According to this embodiment, when the lid body 3 is rotated relative to the main body 2 about the rotation axis 44, the rotational path of the lid body 3 is likely to be located below the upper end surface 221 of the main body 2. Therefore, when the lid body 3 is rotated relative to the main body 2 about the rotation axis 44, the lid body 3 is less likely to come into contact with an object located above the upper end surface 221.
[0080] In the distribution board (1) of the eighth aspect, in any one of the first to seventh aspects, the hinge (4) is a torque hinge.
[0081] According to this embodiment, when a torque equal to or greater than a predetermined torque is not applied to the lid body (3), the lid body (3) can be prevented from moving.
[0082] In the distribution board (1) of the ninth aspect, in any one of the first to eighth aspects, the main body (2) has a recess (223). The recess (223) accommodates at least a part of the hinge (4).
[0083] According to this embodiment, the hinge (4) can be efficiently accommodated in the main body (2).
[0084] In the distribution board (1) of the tenth aspect, in the ninth aspect, the main body (2) has a plate cover (23) that covers the recess (223).
[0085] According to this embodiment, it is possible to prevent foreign matter such as dust and moisture from entering the recess (223).
[0086] The configurations according to the second to tenth aspects are not essential for the distribution board (1) and can be omitted as appropriate. [Explanation of symbols]
