Description

[Technical field]

[0001] The present invention relates to a distribution board and a covering member. [Background technology]

[0002] As described in Patent Document 1, a distribution board having a wiring port for pulling in wiring on the rear side is known. Such a distribution board is used by connecting cables pulled out from the rear of the wall through holes provided on the installation surface such as a wall to the power distribution device inside the distribution board. For this reason, these distribution boards are provided with a wiring port that extends over substantially the entire rear surface of the body member that is fixed to the installation surface such as a wall.

[0003] In recent years, the spread of electrical equipment has led to more opportunities to use electricity than ever before. This has resulted in demands for changes to trunk capacity, an increase in the number of branch circuits, and the addition of functions for solar power generation and EVs and PHEVs. In addition, distribution boards and other panels deteriorate due to the effects of the external environment over many years of use, so it is recommended that panels used for a certain period of time be replaced.

[0005] On the other hand, new distribution boards are often smaller than conventional ones with the same performance. This is because the devices installed inside are often smaller. However, the wall where the existing distribution board was installed has holes for pulling out the cables from behind the wall, and if a new, smaller distribution board is installed in the same position, there is a risk that these holes and the mounting holes of the existing distribution board will be exposed.

[0006] To solve this problem, it is conceivable to select a replacement distribution board of the same size as the existing distribution board or a larger size and install it. In this way, the hole in the wall surface is covered by the replacement distribution board. However, the distribution board is provided with a wiring port that extends over almost the entire back surface of the body member. Since there are few obstacles in front of this wiring port, there is a risk that foreign objects such as dust and pests may enter the distribution board through the hole in the installation surface such as the wall. In addition, it is not very aesthetically pleasing. Summary of the Invention [Problem to be solved by the invention]

[0007] The inventors of the present invention have made extensive research into this issue and have attempted to solve the problem. The problem that the present invention aims to solve is to make it possible to partially block the wiring port of a distribution board. [Means for solving the problem]

[0008] In order to solve the above problems, a distribution board is provided that has a wiring port for pulling in wiring on the rear side, the distribution board has a plurality of mounting holes on the periphery of the wiring port, and is equipped with a covering member having a plate-shaped covering portion that covers the portion of the wiring port that is located to the right or left of the distribution equipment attached to the distribution board, from the top of the wiring port to the bottom of the wiring port.

[0009] It is also preferable that the left-right width of the covering member is an integral multiple of the left-right width of the branch breaker.

[0010] In addition, the covering member is preferably configured to have a dividing portion that can be used to separate the branch breaker at an integer multiple of the left and right width of the branch breaker.

[0011] It is also preferable that the covering member has flexible mounting protrusions on both ends, and that the covering member is fixed by pushing the mounting protrusions into the mounting holes.

[0012] The covering member is attached to a distribution board having a wiring port on the back side for pulling in wiring, and includes a plate-shaped covering portion capable of covering the wiring port from the top to the bottom, and an attachment portion used to attach the covering member. Effect of the Invention

[0013] In the present invention, the wiring port of the distribution board can be partially blocked. [Brief description of the drawings]

[0015] An embodiment of the invention will be described below. As can be seen from Figs. 1 to 4, the distribution board 1 of this embodiment is provided with a wiring port 12 for drawing in wiring on the rear side. This distribution board 1 is provided with a plurality of mounting holes 13 on the periphery of the wiring port 12, and is provided with a covering member 70 having a plate-shaped covering portion 71 that covers the portion of the wiring port 12 located to the right or left of the power distribution device 21 attached to the distribution board 1 from the upper part of the wiring port 12 to the lower part of the wiring port 12. This allows the wiring port 12 of the distribution board 1 to be partially blocked.

[0016] Here, an overview of the distribution board 1 will be described. The distribution board 1 has a body member 11 that is fixed to an installation surface such as a wall. As can be seen from Fig. 3, this body member 11 is provided with a wiring port 12 for drawing in wiring from the rear side of the distribution board 1. In addition, a plurality of mounting holes 13 are provided on the periphery of this wiring port 12.

[0017] Distribution equipment 21 such as a main breaker 21a and branch breakers 21b are mounted on the distribution board 1. In the embodiment, as can be seen from Fig. 4, a mounting base 22 on which the distribution equipment 21 is attached is fixed to the body member 11, and the distribution equipment 21 is mounted on the distribution board 1. Note that the distribution equipment 21 may be fixed to the mounting base 22 fixed to the body member 11.

[0018] There are various methods for fixing the mounting base 22 to the body member 11, but in the example shown in Figures 1 and 2, the mounting rail 23 is fixed to the body member 11 using some of the multiple mounting holes 13 provided around the periphery of the wiring port 12, and the mounting base 22 is fixed to this mounting rail 23. In this example, the mounting base 22 is fixed so as to span two mounting rails 23, but this is not necessary as a limitation. For example, the mounting base 22 may be fixed to the body member 11 using the mounting holes 13 provided on the left and right ends of the wiring port 12 and the mounting holes 13 provided in the mounting rail 23.

[0019] When using a distribution board 1 that is relatively large in the left-right direction, if the members required for fixing the power distribution equipment 21, such as the mounting base 22, are simply fixed to the body member 11, a part of the wiring port 12 located to the right or left of the mounting base 22 may appear large from the front side. In the present invention, a covering member 70 is used to cover such a part, that is, a part of the wiring port 12. In the example shown in Fig. 2, the covering member 70 is attached to the right side of the power distribution equipment 21, and in the example shown in Fig. 5, the covering member 70 is attached to the left side of the power distribution equipment 21.

[0020] 6 and 7 includes a plate-shaped covering portion 71 capable of covering the wiring port 12 from the top to the bottom. The covering member 70 also includes mounting portions 72 used to attach the covering member 70 to the body member 11 or the like. More specifically, the mounting portions 72 are provided on both end sides of a plate-shaped member including the plate-shaped covering portion 71. The mounting portion 72 is provided with a mounting surface 72a capable of facing the mounting hole 13. The mounting surface 72a also includes a mounting protrusion 72b capable of being inserted into the mounting hole 13.

[0021] 6 and 7, since mounting portion 72 and covering portion 71 can be arranged so as to be shifted toward the rear, a portion formed by mounting portion 72, covering portion 71, and connecting portion 73 connecting them is configured to have a hat shape in a side view. If covering portion 71 is configured to be located toward the rear side of mounting portion 72, a large space can be secured inside distribution board 1.

[0022] In the example shown in Figures 6 and 7, in order to enable the covering portion 71 to be positioned on the rear side, the covering portion 71 is configured to be shifted relative to the mounting portion 72 toward the side where the mounting protrusion 72b extends from the mounting surface 72a.

[0023] In the embodiment, the covering member 70 is disposed adjacent to the mounting rail 23 having the cutout 23a on the rear side, but since the covering portion 71 is disposed on the rear side of the mounting portion 72, a cable can be passed through the cutout 23a when wiring between the power distribution devices 21 attached to the distribution board 1 (see Figs. 1 and 8). Therefore, a structure can be achieved that makes it easy to wire inside the distribution board 1 while covering unused parts of the wiring port 12.

[0024] Incidentally, the covering member 70 of the embodiment is made of a resin material. When the covering member 70 is made of a resin material, the mounting protrusions 72b can be made flexible, and it becomes possible to fix the covering member 70 simply by inserting the mounting protrusions 72b into the mounting holes 13. It should be noted that the covering member 70 does not necessarily have to be made of a resin material and may be made of, for example, a metal.

[0025] The covering member 70 of the embodiment can be easily attached by pushing the mounting protrusions 72b of the covering member 70 into the mounting holes 13 provided around the periphery of the wiring port 12 of the body member 11, whereby the mounting protrusions 72b are deformed and fitted into the mounting holes 13. The covering member 70 can also be easily removed. Note that such mounting protrusions 72b are not essential. The covering member 70 may be fixed to the body member 11, etc., using screws, bushings, etc.

[0026] In addition, it is preferable that the width of the covering member 70 is an integer multiple of the width of the branch breaker 21b. The interval between the multiple mounting holes 13 located on the periphery of the wiring port 12 is the length of the width of the branch breaker 21b. Therefore, when mounting the mounting rail 23, etc., the mounting rail 23 can be selected to be mounted offset by an integer multiple of the width of the branch breaker 21b. This offset corresponds to the offset in the left-right direction (or in the up-down direction in some cases) of the opening to be blocked. Therefore, if the width of the covering member 70 is formed to be an integer multiple of the width of the branch breaker 21b, it is possible to cover most of the desired area by using one or more covering members 70.

[0027] In addition, the example covering member 70 shown in Figures 6 and 7 is made by arranging two covering members each having a width equivalent to two circuits of branch breaker 21b, that is, covering member 70 having a width four times the width of branch breaker 21b.

[0028] The covering member 70 of the embodiment has a structure including a dividing portion 75 that can be used to separate the branch breaker 21b at an integral multiple of its left-right width. In the example shown in Fig. 6 and Fig. 7, one covering member 70 is formed with a width corresponding to four circuits of the branch breaker 21b, and the covering member 70 can be easily separated in half (i.e., the width corresponding to two circuits of the branch breaker 21b).

[0029] 6 and 7, a slit is provided at the location where it can be separated to become a separation section 75. If a guide such as a slit is provided in the covering member 70, it can be separated without using scissors or other tools, and the required width can be appropriately adjusted.

[0030] As can be seen from the example shown in Figure 9, the covering member 70 can be used not only to cover the wiring ports 12 located to the right or left of the distribution equipment 21 attached to the distribution board 1, but also to cover the wiring ports 12 on the rear side of the installation position of the distribution equipment 21.

[0031] Some distribution boards 1 are provided with mounting holes 13 with different mounting positions in the front-to-rear direction, in which case the mounting holes 13 located at the front can be used to fasten the mounting base 22 to which the power distribution device 21 is fixed, and the mounting holes 13 located at the rear can be used to attach the covering member 70. In this way, the wiring port 12 on the back side of the mounting base 22 can be covered by the covering member 70.

[0032] It is preferable that the covering member 70 can be partially machined to have cut portions 74 such as slits or holes. For example, if the cut portions 74 can be provided in the covering member 70 using scissors or a tool, when the amount of wiring to be pulled into the power distribution device 21 is small, the wiring can be passed through the cut portions 74 provided in a part of the covering member 70, making it easier to perform wiring work while increasing the covered area. In addition, the airtightness of the distribution board 1 can be improved.

[0033] Incidentally, the covering member 70 can have various configurations other than those shown in Figures 6 and 7, and examples of these are described below. The example shown in Figures 10 and 11 is a configuration in which the covering portion 71 of the covering member 70 can be positioned forward of the mounting portion 72. With such a configuration, it becomes possible to position the covering portion 71 forward of the cutout portion 23a of the mounting rail 23, and it is possible to further improve airtightness (see Figure 12).

[0034] In the example shown in Figures 10 and 11, in order to enable the covering portion 71 of the covering member 70 to be positioned forward of the mounting portion 72, the covering portion 71 is configured to be shifted relative to the mounting portion 72 on the side opposite to the side where the mounting protrusion 72b extends from the mounting surface 72a.

[0035] Also, as shown in Figures 13 and 14, the covering portion 71 and the attachment portion 72 may be configured to be located on the same plane. In the example shown in Figures 13 and 14, both ends of the flat portion are the attachment portion 72, and the center of the flat portion is the covering portion 71. With such a simple configuration, it is not bulky and is convenient for carrying multiple covering members 70. When the covering member 70 of this example is attached, it becomes as shown in Figure 15.

[0036] In addition, in the examples described so far, the mounting portion 72 is provided at the longitudinal end of the covering member 70, but the mounting portion 72 may be formed at the lateral end of the covering member 70 (see Figs. 16 and 17). In this case, the mounting protrusions 72b formed on the mounting portion 72 may be attached to the left and right sides of the wiring port 12 or to mounting holes 13 provided in the mounting rail 23 (see Figs. 18 and 19). Also, a configuration in which the mounting portion 72 is provided at both the longitudinal end and the lateral end may be adopted.

[0037] Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be in various forms. For example, the covering portion 71 of the covering member 70 does not necessarily have to be rectangular in front view, and it is sufficient that it covers the upper part of the wiring port 12 and the lower part of the wiring port 12, and it can be in a different shape.
