[0009] Preferred embodiments of the present disclosure will be described in detail below with reference to the drawings. Common elements in the embodiments described below are designated by the same reference numerals, and redundant descriptions of the common elements may be omitted. The following embodiments and modifications are merely a portion of the various embodiments of the present disclosure. Various modifications of the following embodiments and modifications can be made depending on the design, etc., as long as the object of the present disclosure can be achieved. The configurations of the modifications can also be combined as appropriate.

[0010] The drawings described in this disclosure are schematic diagrams, and the ratios of the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensional ratios. Note that the arrows indicating the directions in the drawings are merely examples and are not intended to define the directions when the distribution board 1 is in use. Also, the arrows indicating the directions in the drawings are merely shown for explanatory purposes and do not have any substance.

[0011] In this disclosure, "orthogonal (perpendicular)" refers not only to a state where the angle between two things is exactly 90 degrees, but also to a state where two things intersect within a certain range of difference. In other words, the angle between two orthogonal things is within a certain range of difference from 90 degrees (for example, 10 degrees or less). In other words, "orthogonal" in this disclosure includes a case where the angle between two things is between 80 degrees and 100 degrees. Similarly, "parallel" in this disclosure includes not only a case where two things do not strictly intersect, but also a case where two things are lined up within a certain range of difference. For example, "parallel" in this disclosure includes a case where one thing is inclined at an angle of 10 degrees or less relative to the other. In other words, "parallel" in this disclosure includes a case where the angle between one thing and the other is between -10 degrees and 10 degrees.

[0012] (1) Overview First, an overview of a distribution board 1 according to this embodiment will be described with reference to FIGS. 1 to 3. FIG.

[0013] As shown in FIG. 1, the distribution board 1 includes a cabinet 2. As shown in FIGS. 2 and 3, the distribution board 1 also includes a plurality of branch breakers 3, a fixing member 5, and a display member 4. The plurality of branch breakers 3, the fixing member 5, and the display member 4 are housed inside the cabinet 2. Note that the term "housed" in this disclosure is intended to include not only cases where one object completely surrounds another object, but also cases where one object surrounds another object so that a portion of the other object is exposed from the first object. For example, the plurality of branch breakers 3, the fixing member 5, and the display member 4 may be exposed from the cabinet 2.

[0014] The branch breakers 3 are arranged side by side in a first direction D1 (see FIG. 3) that is perpendicular to the front-rear direction of the distribution board 1. In this embodiment, the first direction D1 is the left-right direction.

[0015] Here, the front-to-rear direction of the distribution board 1 is the direction along the normal to the wall surface when the distribution board 1 is installed on a wall, for example. Furthermore, in this embodiment, when the distribution board 1 is installed on a wall, the distribution board 1 is located in front of the wall surface, and the wall surface is located behind the distribution board 1. In this embodiment, the front-to-rear direction is the third direction D3 (see FIG. 3).

[0016] The display member 4 is arranged to be aligned with the operating units 32 (handles) of the branch breakers 3 in a second direction D2 (see FIG. 3) that is perpendicular to both the front-rear direction and the first direction D1. The display member 4 has a display surface 41 (see FIG. 3) that is configured to be able to display information about the loads connected to each of the branch breakers 3. In this embodiment, the second direction D2 is the up-down direction. In this embodiment, the up-down direction is parallel to the vertical direction.

[0017] The fixing member 5 is disposed in front of the plurality of branch breakers 3. The fixing member 5 fixes the plurality of branch breakers 3. As shown in FIG. 3 , the fixing member 5 has a base 51 having a front surface 510 and a holding portion 52 that holds the display member 4.

[0018] The holding portion 52 holds the display member 4 so that the display surface 41 of the display member 4 faces forward.

[0019] According to the distribution board 1 of this embodiment, the display surface 41 of the display member 4 is held so as to face forward by the holding portion 42 of the fixing member 5 that fixes the multiple branch breakers 3. This allows the display surface 41 to be positioned in a position that is easily visible to the worker when connecting electric wires to the multiple branch breakers 3. According to the distribution board 1 of this embodiment, the visibility of the display member 4 can be improved compared to, for example, a distribution board in which the display member is provided on the cover of a cabinet.

[0020] (2) Details Hereinafter, a detailed configuration of the distribution board 1 according to this embodiment will be described with reference to FIGS.

[0021] (2.1) Overall structure The distribution board 1 is installed and used in a facility such as a dwelling unit of a detached house or an apartment building. In this embodiment, the case where the distribution board 1 is a residential board installed in a dwelling unit is exemplified. Note that the facility in which the distribution board 1 is installed is not limited to each dwelling unit of a detached house or an apartment building, and the distribution board 1 may also be installed in a non-residential building (for example, a factory, a commercial building, an office building, a hospital, a school, etc.).

[0022] In addition, in this embodiment, a case where the distribution board 1 is used in a single-phase three-wire power distribution system is illustrated. However, the distribution board 1 may also be used in a three-phase three-wire or three-phase four-wire power distribution system.

[0023] As shown in FIGS. 1 to 3, the distribution board 1 includes a cabinet 2, a main breaker, a plurality of branch breakers 3, a light-transmitting cover 7, a display member 4, and a fixing member 5.

[0024] (2.2) Cabinet configuration The cabinet 2 is shaped like a rectangular box. The cabinet 2 is a member made of synthetic resin or metal. As shown in FIG. 1, the cabinet 2 has a cover 21 and a base (not shown). The cover 21 is shaped like a rectangular box with an open rear surface. The base is shaped like a rectangular box with an open front surface. The base is attached to, for example, a wall surface of a facility.

[0025] A mounting plate 6 (see FIG. 2) is attached to the base. A plurality of branch breakers 3, a fixing member 5, etc. are attached to the mounting plate 6. In other words, a plurality of branch breakers 3, a fixing member 5, etc. are attached to the base. By attaching a cover 21 to the base, the cabinet 2 accommodates a plurality of branch breakers 3, a display member 4, a fixing member 5, etc. In other words, a plurality of branch breakers 3, a display member 4, a fixing member 5, etc. are arranged in a space surrounded by the base and the cover 21.

[0026] An opening 211 is formed in the front surface 210 of the cover 21. The opening 211 is a through-hole that penetrates the front surface 210 in the front-to-rear direction. The opening 211 exposes the operation units 32 of the multiple branch breakers 3 and the display members 4 to the outside of the cabinet 2. Because the cover 21 has the opening 211, a user of the distribution board 1, such as a resident of the dwelling unit, can visually check the display members 4 exposed from the opening 211 and operate the operation units 32 of the branch breakers 3 without removing the cover 21 from the base.

[0027] (2.3) Breaker configuration Since the distribution board 1 of this embodiment is used in a single-phase, three-wire power distribution system, three single-phase, three-wire service lines of a system power supply (commercial power supply) are electrically connected to the primary terminal of the main breaker. Furthermore, a conductive bar of a first voltage pole (L1 phase), a conductive bar of a second voltage pole (L2 phase), and a conductive bar of a neutral pole (N phase) are electrically connected to the secondary terminal of the main breaker. In the following description, the conductive bar of the neutral pole may be referred to as an "N bar 8 (see FIG. 4)."

[0028] As shown in Fig. 2, the plurality of branch breakers 3 includes a first branch breaker group 3A and a second branch breaker group 3B. In the first branch breaker group 3A, a plurality of branch breakers 3 (10 in the example of Fig. 2) are lined up in a first direction D1. In the second branch breaker group 3B, a plurality of branch breakers 3 (13 in the example of Fig. 2) are lined up in the first direction D1. The first branch breaker group 3A and the second branch breaker group 3B are lined up in a second direction D2.

[0029] The branch breaker 3 includes a primary terminal and a secondary terminal. The branch breaker 3 has a contact portion electrically connected between the primary terminal and the secondary terminal. The branch breaker 3 also includes a housing that houses the contact portion. The front surface of the housing of the branch breaker 3 is provided with an operation portion 32 that is operated by the user to turn the contact portion on or off. A connection portion 33 is also provided on a surface that intersects with the front surface. The connection portion 33 is a portion that is connected to a conductive bar.

[0030] The branch breakers 3 are available for 100V and 200V. The primary terminals of the 100V branch breaker 3 are electrically connected to one of the conductive bars of the first voltage pole and the second voltage pole, and to the conductive bar of the neutral pole. The pair of primary terminals of the 200V branch breaker 3 are electrically connected to the conductive bar of the first voltage pole and the conductive bar of the second voltage pole, respectively. Corresponding electric wires are electrically connected to the secondary terminals of the branch breaker 3. One or more loads, such as electrical appliances such as lighting fixtures and hot water supply equipment, or wiring devices such as outlets or wall switches, are connected to the electric wires connected to the secondary terminals of the branch breaker 3. Therefore, the distribution board 1 can supply power to electrical appliances connected to the secondary terminals of the branch breaker 3 via electric wires, or to electrical appliances connected to the outlets (e.g., air conditioners, television sets, etc.).

[0031] The branch breaker 3 is equipped with a tripping circuit that turns off the contacts when an overcurrent such as a short-circuit current or an overload current flows through the contacts. The tripping circuit includes, for example, an electromagnet device that includes an exciting coil that forms part of the electrical circuit inside the branch breaker 3. The branch breaker 3 also has a leakage current interrupter mechanism that turns off the contacts when it detects a leakage current flowing through the contacts.

[0032] As shown in FIG. 7, the branch breaker 3 has a plurality of first protrusions 31 (two in the example of FIG. 7). The first protrusions 31 are formed on the surface of the housing on which the operation unit 32 is provided. When the branch breaker 3 is fixed to the fixing member 5, the first protrusions 31 protrude from the housing in the front-to-rear direction (i.e., the third direction D3). More specifically, when the branch breaker 3 is fixed to the fixing member 5, the first protrusions 31 protrude forward from the housing.

[0033] As will be described later in the section "(3) Method of installing the branch breaker," the first protrusion 31 of the branch breaker 3 hooks onto the second protrusion 56 of the fixing member 5, thereby fixing the branch breaker 3 to the fixing member 5.

[0034] (2.4) Structure of the light-transmitting cover The light-transmitting cover 7 (see FIG. 3) is light-transmitting. The light-transmitting cover 7 is a member made of a light-transmitting synthetic resin such as an acrylic resin or a polycarbonate resin. The light-transmitting cover 7 has a flat plate-like shape. For example, the light-transmitting cover 7 has the same shape as the display member 4.

[0035] The light-transmitting cover 7 is held by the holding portion 52 of the fixing member 5. More specifically, the light-transmitting cover 7 is held by the holding portion 52 in front of the display member 4 so that the display member 4 is sandwiched between the light-transmitting cover 7 and the fixing member 5. This makes it possible to prevent the display member 4 from falling off and from becoming soiled.

[0036] (2.5) Display component configuration The display member 4 (see FIG. 3) has a display surface 41. The display surface 41 is configured to be able to display information about the loads connected to each of the multiple branch breakers 3. The information about the loads includes information indicating the load names. The load names are the names of the electrical equipment or wiring devices that are the loads. The information about the loads may also include information indicating the location where the electrical equipment or wiring devices that are the loads are used (or installed), and information indicating the load number.

[0037] 2, area lines 411 are formed on the display surface 41. The area lines 411 are lines that divide the display surface 41 into a plurality of areas. The area lines 411 may be formed by the shape of the display surface 41, such as a convex portion or a concave portion, or may be formed by writing with ink or the like, for example.

[0038] The display surface 41 has a plurality of first areas A1 and a plurality of second areas A2 divided by area lines 411. The plurality of first areas A1 correspond one-to-one to the plurality of branch breakers 3. The plurality of second areas A2 correspond one-to-one to the plurality of branch breakers 3. For example, the first area A1 is an area that displays the load name of the corresponding branch breaker 3. For example, the second area A2 is an area that displays the number of the corresponding branch breaker 3.

[0039] It should be noted that the display surface 41 does not necessarily need to display information about the load when the distribution board 1 is shipped. The display surface 41 may be configured to display information about the load by writing on it with a writing implement or by attaching a sticker or the like after the distribution board is shipped.

[0040] The display member 4 of this embodiment is formed in a sheet shape. However, the display member 4 may be formed in a flat plate shape. Furthermore, the display member 4 of this embodiment is formed from paper. This makes it easy to write information about the load on the display surface 41 using a writing implement or the like.

[0041] (2.6) Configuration of fixing members The fixing member 5 fixes the plurality of branch breakers 3. The fixing member 5 is disposed in front of the plurality of branch breakers 3. The fixing member 5 is made of synthetic resin. As shown in FIGS. 4 and 5 , the fixing member 5 has an overall rectangular flat plate shape. The fixing member 5 has a base 51 and a holding portion 52.

[0042] The base 51 as a whole has a rectangular, flat plate-like shape. The base 51 has a front surface 510 and a rear surface 55 (see FIG. 6) opposite the front surface 510. The base 51 also has a plurality of (two in the example of FIG. 5) first through holes 53 and a plurality of (eight in the example of FIG. 5) second through holes 54. The first through holes 53 and the second through holes 54 are holes that penetrate the base 51 in the front-to-rear direction.

[0043] 4, the fixing member 5 in this embodiment is disposed in front of the N bar 8. The fixing member 5 is also fixed to a plurality of bar supports 61 via the N bar 8. The plurality of bar supports 61 protrude forward from the mounting plate 6.

[0044] More specifically, the fixing member 5 is fixed to the multiple bar supports 61 via the N bars 8 by fitting a screw that passes through the second through hole 54 of the fixing member 5 and the second through hole 82 of the N bar 8 into a screw hole in the bar support 61. The N bars 8 are fixed to the bar supports 61 by fitting a screw that passes through the first through hole 81 of the N bar 8 into a screw hole in the bar support 61. When the fixing member 5 is fixed to the bar support 61, the first through hole 53 of the fixing member 5 surrounds the periphery of the head of the screw that passes through the first through hole 81 of the N bar 8 and fits into the screw hole of the bar support 61.

[0045] As shown in FIG. 6, the fixing member 5 has a plurality of second protrusions 56 (two in the example of FIG. 6). The second protrusions 56 correspond one-to-one to the first protrusions 31 (see FIG. 7) of the branch breakers 3. The second protrusions 56 protrude in the front-to-rear direction. The second protrusions 56 are formed on the rear surface 55 of the base 51 and protrude rearward from the rear surface 55.

[0046] The fixing member 5 also has a plurality of guide portions 57 (two in the example of FIG. 6 ) that correspond one-to-one with the plurality of second protrusions 56. The guide portions 57 are formed on the rear surface 55 of the base 51. The guide portions 57 are grooves that extend along the second direction D2 (or the up-down direction). In the second direction D2, the guide portions 57 are aligned with the corresponding second protrusions 56. The guide portions 57 guide the first protrusions 31 of the branch breaker 3 toward the corresponding second protrusions 56 when the branch breaker 3 is attached to the fixing member 5.

[0047] As shown in Fig. 5, the fixing member 5 has a first wall 511 (upper wall) and a second wall 512 (lower wall). The first wall 511 is formed along the left-right direction over the entire area of ​​the upper end of the base 51. The first wall 511 protrudes forward from a front surface 510 of the base 51. The second wall 512 is formed along the left-right direction over the entire area of ​​the lower end of the base 51. The second wall 512 protrudes forward from the front surface 510 of the base 51.

[0048] The fixing member 5 also has a third wall 513 (upper wall). The third wall 513 is formed near the center between the first wall 511 and the second wall 512 in the up-down direction. The third wall 513 is formed along the left-right direction from the right end of the base 51. In the left-right direction, the right end of the first wall 511 and the left end of the third wall 513 are at approximately the same position. The third wall 513 protrudes forward from the front surface 510 of the base 51. In a front view of the distribution board 1, the first wall 511, the second wall 512, and the third wall 513 are parallel walls.

[0049] As shown in FIG. 2, the holding portion 52 holds the display member 4 in front of the base 51 (see FIG. 3) so that the display surface 41 of the display member 4 faces forward. The holding portion 52 also holds the light-transmitting cover 7 together with the display member 4. The holding portion 52 holds the light-transmitting cover 7 so that the light-transmitting cover 7 is located in front of the display member 4. In other words, the holding portion 52 holds the display member 4 and the light-transmitting cover 7 so that the display member 4 is sandwiched between the light-transmitting cover 7 and the front surface 510 of the base 51 (see FIG. 3) in the front-rear direction.

[0050] As shown in FIG. 5, the holding portion 52 of this embodiment has a plurality of claws 52A, 52B. More specifically, the holding portion 52 has a plurality of claws 52A (four in the example of FIG. 5) formed on the first wall 511, a claw 52A formed on the third wall 513, and a plurality of claws 52B (five in the example of FIG. 5) formed on the second wall 512. The four claws 52A formed on the first wall 511 correspond one-to-one to the four leftmost claws 52B of the five claws 52B formed on the second wall 512. Furthermore, the claw 52A formed on the third wall 513 corresponds to the rightmost claw 52B of the five claws 52B formed on the second wall 512. In other words, the plurality of claws 52A, 52B of this embodiment includes five pairs of claws 52A, 52B. The pair of claws 52A, 52B face each other in the second direction D2 (vertical direction) and protrude toward each other. More specifically, the claw 52A (upper claw) protrudes downward, and the claw 52B (lower claw) protrudes upward. The claws 52A, 52B are shaped like rectangular flat plates.

[0051] In the front-rear direction, there is a space between the claws 52A, 52B and the front surface 510 of the base 51 for sandwiching the display member 4 and the light-transmitting cover 7. That is, the multiple claws 52A, 52B hold the display member 4 by sandwiching it between the multiple claws 52A, 52B and the base 51 in the front-rear direction. In this embodiment, the multiple claws 52A, 52B hold the display member 4 and the light-transmitting cover 7 by sandwiching it between the multiple claws 52A, 52B and the base 51 in the front-rear direction. Holding the display member 4 and the light-transmitting cover 7 with the multiple claws 52A, 52B allows the display member 4 and the light-transmitting cover 7 to be held more firmly. Furthermore, holding the display member 4 and the light-transmitting cover 7 with a pair of claws 52A, 52B allows the display member 4 and the light-transmitting cover 7 to be held in a more balanced manner.

[0052] 2, the holding portion 52 holds the display member 4 so that the display member 4 is sandwiched between the operation unit 32 of the first branch breaker group 3A and the operation unit 32 of the second branch breaker group 3B in the second direction D2 (vertical direction). In other words, when viewed from the front of the distribution board 1, the display member 4 is located between the operation unit 32 of the first branch breaker group 3A and the operation unit 32 of the second branch breaker group 3B in the vertical direction. This allows the display member 4 to be positioned so that it is easily visible both when connecting electric wires to each of the first branch breaker group 3A and when connecting electric wires to each of the second branch breaker group 3B. In other words, the visibility of the display member 4 can be further improved.

[0053] (3) How to install a branch breaker A method for mounting (or fixing) the branch breaker 3 will be described with reference to FIGS.

[0054] In the distribution board 1 of this embodiment, a fixing member 5 is attached to the mounting plate 6 (or bar support 61), and then multiple branch breakers 3 are attached to the fixing member 5 and the mounting plate 6. The multiple branch breakers 3 are attached in the gap between the fixing member 5 and the mounting plate 6. The branch breakers 3 of the first branch breaker group 3A are attached to the fixing member 5 and the mounting plate 6 by sliding them downward into the gap between the fixing member 5 and the mounting plate 6 with the connection parts 33 facing downward and the operation parts 32 facing forward. The branch breakers 3 of the second branch breaker group 3B are attached to the fixing member 5 and the mounting plate 6 by sliding them upward into the gap between the fixing member 5 and the mounting plate 6 with the connection parts 33 facing upward and the operation parts 32 facing forward.

[0055] More specifically, when the branch breakers 3 of the second branch breaker group 3B are pushed upward with their first protrusions 31 fitted into the guide portions 57 of the fixing member 5 (see FIG. 7 ), the first protrusions 31 slide upward as they are guided by the guide portions 57. In other words, when attaching the branch breakers 3 to the fixing member 5, the guide portions 57 guide the first protrusions 31 toward the corresponding second protrusions 56. This improves the workability when attaching the branch breakers 3 to the fixing member 5 and the mounting plate 6.

[0056] Then, the first protrusion 31 pushes the second protrusion 56 of the fixing member 5 forward, and the first protrusion 31 is moved above the second protrusion 56 of the fixing member 5, causing the second protrusion 56, which has returned to its original position, to become engaged with the first protrusion 31 (see FIG. 8). As a result, the branch breakers 3 of the second branch breaker group 3B are fixed to the fixing member 5. In other words, the first protrusion 31 of the branch breaker 3 and the second protrusion 56 of the fixing member 5 are configured to become engaged with each other when the branch breakers 3 are fixed by the fixing member 5.

[0057] When the branch breakers 3 of the first branch breaker group 3A are pushed downward with the first protrusions 31 fitted into the guide portions 57 of the fixing member 5, the first protrusions 31 slide downward while being guided by the guide portions 57. The first protrusions 31 then push the second protrusions 56 of the fixing member 5 forward, and the first protrusions 31 move downward below the second protrusions 56 of the fixing member 5, causing the second protrusions 56, which has returned to its original position, to engage with the first protrusions 31. This fixes the branch breakers 3 of the first branch breaker group 3A to the fixing member 5.

[0058] (4) Variations Modifications of the above embodiment are listed below.

[0059] In the above embodiment, the pair of claws 52A, 52B face each other in the second direction D2. However, it is not essential that the claws 52A, 52B face each other in the second direction D2, and the claws 52A, 52B may be formed so as not to face each other in the second direction D2.

[0060] In the above embodiment, the holding portion 52 has a plurality of claws 52A, 52B. However, it is not essential that the holding portion 52 has a plurality of claws 52A, 52B. For example, the holding portion 52 may have one or more clip portions that hold the display member 4 by pressing it against the front surface 510 of the base 51. The holding portion 52 may also have a bridge portion that connects the first wall 511 and the second wall 512 along the second direction D2. However, it is preferable that the length (width) of the bridge portion in the first direction D1 be as short (narrow) as possible so as not to reduce the visibility of the display member 4.

[0061] In the above embodiment, the display member 4 is made of paper. However, the display member 4 may be made of other materials. The display member 4 may be made of synthetic resin, wood, metal, or the like.
