Patent Document 1

[0006] The present invention relates to a control panel enclosure 10, which is a mounting device for mounting equipment inside the control panel enclosure, the mounting device having a planar box mounting surface 2 that is attached to the control panel enclosure and a planar equipment mounting surface 3 for mounting equipment, the equipment mounting surface 3 being attached to the box mounting surface 2 in an oblique position, and the oblique position angle α formed by the equipment mounting surface 3 and the box mounting surface 2 being 5° or more and 85° or less, the control panel enclosure having a door 10a that can be opened and closed on the front side, and the box mounting surface 2 of the mounting device 1 being attached to the rear side surface, and when the equipment 20 is positioned obliquely inside the control panel enclosure via the mounting device 1, the distance from the front end of the equipment 20 to the rear end of the box mounting surface 2 is shorter than the front-to-back length inside the control panel enclosure, the equipment mounting surface 3 is directly attached to the box mounting surface 2, and the box mounting surface 2 is directly attached to the rear side surface of the control panel enclosure. In the aforementioned diagonally positioned state, a separate device 20' is attached to the box mounting surface 2 on the rear side of the device mounting surface 3, and the separate device 20' is an adapter 20A' for the device 20. Its first characteristic is this.

[0008] A second feature of the board box 10 according to the present invention is, in addition to the first feature described above, ,before The oblique angle α is between 30° and 60°.

[0009] These features allow the angle α formed by the equipment mounting surface 3 and the box mounting surface 2 to be greater than 0° and less than 90°. Unlike in Patent Document 1 (the conventional example shown in Figure 1(a)), where each piece of equipment is arranged approximately parallel to the rear surface of the enclosure body 10, resulting in a large empty space in front of equipment with a short front-to-back length and ineffective use of space within the enclosure body, even if the equipment 20 has a short front-to-back length, as shown in Figure 1(b), the equipment 20 can be arranged across the front-to-back direction within the enclosure body 10, improving the space efficiency within the enclosure body 10 ("effective use of space inside the enclosure") and enabling a more compact enclosure body 10 (especially in front view). Furthermore, since the present invention arranges the equipment 20 diagonally within the enclosure 10 via the mounting bracket 1, it can also be said to be a "diagonal arrangement of equipment within the enclosure."

[0010] Furthermore, by using a mounting fixture 1 to which a box mounting surface 2 is attached to the rear surface inside the enclosure 10, the distance from the front end of the equipment 20 to the rear end of the box mounting surface 2 is made shorter than the front-to-back length inside the enclosure 10, even when the equipment 20 is positioned diagonally inside the enclosure 10. This maximizes the effective use of space inside the enclosure while allowing the equipment 20 to be housed inside the enclosure 10.

[0011] Furthermore, by attaching another piece of equipment 20' to the rear side of the equipment mounting surface 3, even greater "effective use of space inside the panel" can be achieved. [Effects of the Invention]

[0012] According to the mounting fixture and enclosure body of the present invention, by making the angle between the enclosure mounting surface and the equipment mounting surface greater than 0° and less than 90°, it is possible to achieve "effective use of space inside the enclosure". [Brief explanation of the drawing]

[0013] [Figure 1] This is a schematic plan view showing the difference between the mounting fixture according to the present invention and a conventional example, where (a) shows a conventional example and (b) shows the mounting fixture according to the present invention. [Figure 2]This is a front view showing the mounting fixture and enclosure body according to the present invention. [Figure 3] This is a photograph used as a substitute for a drawing, illustrating a front view of the mounting bracket and the enclosure body. [Modes for carrying out the invention]

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. <Mounting bracket 1> Figures 1 to 3 show the mounting fixture 1 according to the present invention. This mounting device 1 is a device for mounting the equipment 20, which will be described later, inside the enclosure body 10, which will be described later. The equipment 20 is positioned diagonally inside the enclosure body 10 via this mounting device 1. The mounting fixture 1 has a box mounting surface 2 (described later) and an equipment mounting surface 3, and the angle formed by these two surfaces 2 and 3 (the angle between the two surfaces 2 and 3) is the oblique arrangement angle α (described later). In addition, the mounting fixture 1 may have fasteners (such as screws, bolts, and nuts) used when attaching it to the enclosure body 10 or when attaching the equipment 20.

[0015] The material of the mounting bracket 1 is not particularly limited, but it may be metals such as stainless steel (SUS304, etc.), steel, cast iron, or aluminum, or it may be FRP (Fiber Reinforced Plastics), plastic (synthetic resin), rubber (synthetic rubber), wood, or stone, or a combination of these (the box mounting surface 2 and the equipment mounting surface 3 may be made of the same material or different materials). In the mounting fixture 1, the equipment mounting surface 3 is attached to the box mounting surface 2 in an oblique position. Alternatively, one surface member may be bent to form both the box mounting surface 2 and the equipment mounting surface 3, or each surface portion 2 and 3 may be a single surface member, which may be attached together (by welding, adhesive, or via a fixing device (not shown) with a roughly ∠-shape in side view, or an angle adjustment part (not shown)) to form both the box mounting surface 2 and the equipment mounting surface 3.

[0016] <Box mounting surface 2> As shown in FIGS. 1 to 3, the box mounting surface portion 2 is a part of the above-described fixture 1 and is a planar portion to be mounted in the panel box body 10 described later. In addition, since the device mounting surface portion 3 described later is mounted in a state of being obliquely arranged with respect to the box mounting surface portion 2, it can be said that the box mounting surface portion 2 is a base (supporting the device mounting surface portion 3) of the device mounting surface portion 3. For the box mounting surface portion 2 to be mounted on the panel box body 10, holes for fixtures (through holes), recesses, etc. may be formed. Furthermore, a roughly concave notch may be formed in accordance with the size and shape of the other device 20', for example, to directly attach the other device 20', which will be described later, to the rear surface inside the enclosure 10. OK. The specific configuration of the box mounting surface portion 2 is not particularly limited. For example, its shape may be substantially rectangular, substantially square, substantially triangular, substantially elliptical, or substantially circular, and its corners may be rounded. Hereinafter, the shape of the box mounting surface portion 2 will be mainly described as being substantially rectangular. A roughly concave notch OK.

[0017] The size of the box mounting surface portion 2 is not particularly limited. For example, in the case of a substantially rectangular shape, the length of the long side has a lower limit value of 160 mm or more, preferably 180 mm or more, more preferably 200 mm or more, and an upper limit value of 400 mm or less, preferably 360 mm or less, more preferably 320 mm or less (such as 225 mm or 305 mm). Also, the length of the short side, for example, has a lower limit value of 100 mm or more, preferably 120 mm or more, more preferably 140 mm or more, and an upper limit value of 320 mm or less, preferably 270 mm or less, more preferably 220 mm or less (such as 160 mm or 180 mm). The thickness of the box mounting surface portion 2 is also not particularly limited. For example, the lower limit value is 0.1 mm or more, preferably 0.3 mm or more, more preferably 0.5 mm or more, and the upper limit value is 10.0 mm or less, preferably 5.0 mm or less, more preferably 3.0 mm or less (such as 1.0 mm or 2.0 mm). The box mounting surface portion 2 may be larger than, substantially the same as, or smaller than the device mounting surface portion 3.

[0018] <Device mounting surface portion 3> As shown in Figures 1 to 3, the equipment mounting surface 3 is a part of the mounting fixture 1 described above, and is the planar portion to which the equipment 20, which will be described later, is mounted. Furthermore, since the equipment mounting surface 3 is mounted at an angle to the box mounting surface 2 described above, it can also be said that the equipment mounting surface 3 is supported by the box mounting surface 2. Even if the equipment mounting surface 3 has holes (through holes) or recesses for fasteners for mounting the equipment 20, good . The specific configuration of the equipment mounting surface 3 is not particularly limited, but for example, its shape may be roughly rectangular, roughly square, roughly triangular, roughly elliptical, or roughly circular, and its corners may be rounded. The shape of the equipment mounting surface 3 is as follows: , omitted Let's assume it's rectangular.

[0019] The size of the equipment mounting surface 3 is not particularly limited, but for example, the length of the longer side in a roughly rectangular shape may have a lower limit of 160 mm or more, preferably 180 mm or more, more preferably 200 mm or more, or an upper limit of 400 mm or less, preferably 360 mm or less, more preferably 320 mm or less (such as 225 mm or 305 mm), and the length of the shorter side may have a lower limit of 50 mm or more, preferably 70 mm or more, more preferably 90 mm or more, or an upper limit of 250 mm or less, preferably 200 mm or less, more preferably 150 mm or less (such as 110 mm). The thickness of the equipment mounting surface 3 is not particularly limited, but for example, the lower limit may be 0.1 mm or more, preferably 0.3 mm or more, and more preferably 0.5 mm or more, or the upper limit may be 10.0 mm or less, preferably 5.0 mm or less, and more preferably 3.0 mm or less (such as 1.0 mm or 2.0 mm). The equipment mounting surface 3 may be smaller than, approximately the same size as, or larger than the box mounting surface 2.

[0020] <Oblique angle α> As shown in Figure 1, the oblique angle α is the angle formed by the equipment mounting surface 3 and the box mounting surface 2, and can also be described as the angle between the equipment mounting surface 3 and the box mounting surface 2 in a side view of the mounting fixture 1. The oblique angle α is greater than 0° and less than 90°. The lower limit may be, for example, 5° or more, preferably 10° or more, more preferably 20° or more, and even more preferably 30° or more. The upper limit may be, for example, 85° or less, preferably 80° or less, even more preferably 70° or less, and even more preferably 60° or less (such as 30°, 45°, or 60°).

[0021] <Disc box body 10> As shown in Figures 1 to 3, the control panel 10 is mounted inside (inside the control panel 10) with the equipment 20, which will be described later, positioned diagonally via the mounting bracket 1 described above, and the box mounting surface 2 of the mounting bracket 1 is mounted inside the control panel 10. For a single control panel 10, the number of mounting fixtures 1 and diagonally positioned devices 20 may be one or multiple. Inside the enclosure 10 (inside the enclosure 10), in addition to the diagonally positioned equipment 20, other equipment 20' may be installed, and the number of other equipment 20' installed in one enclosure 10 may be one or multiple. The enclosure 10 is not limited to any specific use as a panel, depending on the equipment 20 installed inside it. For example, it can be used as an enclosure for a remote control panel, a switchboard, a connection panel (connection box), a control panel (control box), etc. Inside such a panel enclosure 10, in addition to the mounting fixtures 1 and the equipment 20 and 20', wiring, wiring ducts, wiring fasteners, etc. may be provided, and through holes for inserting wiring into and out of the panel enclosure 10 may be provided on the lower surface.

[0022] The control panel body 10 may have a door 10a that can be opened and closed on the front side. In other words, the side of the control panel body 10 with the door 10a is the front side, and the opposite side (the back side of the main body 10b of the control panel body 10) is the rear side. In the enclosure body 10, the mounting surface portion 2 of the mounting fixture 1 can be attached from the inside to the rear surface (so to speak, the back surface), as well as to the left surface (left side), the right surface (right side), the upper surface (top surface), the lower surface (bottom surface), and the back surface (rear side) of the door 10a. When mounting fixtures 1 and equipment 20 are attached from the inside of the enclosure body 10, they may be attached directly to the exterior of the enclosure body 10 (the components that make up the exterior), or they may be attached to a circuit board (panel, wood, etc.) 10c that is attached to the exterior from the inside (especially on the rear surface). Furthermore, the door 10a of the panel box 10 may be detachable from the main body 10b of the panel box 10, and the door 10a may open horizontally as shown in Figure 3, but it may also open like double doors (multiple doors 10a for one panel box 10, with these multiple doors 10a opening to the left and right), or vertically (the door 10a opening upward). In addition, the panel box 10 may have a canopy portion 10d that protrudes forward from its top surface.

[0023] The shape of the panel box 10 may be a roughly rectangular parallelepiped or a roughly cubic shape, and there are no particular limitations on its size, but the width may be, for example, a minimum of 200 mm, preferably 300 mm or more, and more preferably 400 mm or more, or an upper limit of 1100 mm or less, preferably 900 mm or less, and more preferably 700 mm or less (such as 452 mm or 500 mm), and the height may be, for example, a minimum of 200 mm or more, and more preferably 300 mm or more. More preferably, the length may be 500 mm or more, or the upper limit may be 1300 mm or less, preferably 1100 mm or less, and even more preferably 900 mm or less (such as 660 mm or 715 mm). The front-to-back length (depth) may, for example, have a lower limit of 110 mm or more, preferably 140 mm or more, and even more preferably 170 mm or more, or an upper limit of 400 mm or less, preferably 350 mm or less, and even more preferably 300 mm or less (such as 209 mm or 250 mm).

[0024] <Device 20, another device 20'> As shown in Figures 1 to 3, the device 20 is installed in the aforementioned enclosure 10 in an oblique position via the aforementioned mounting bracket 1, with the device 20 being attached to the device mounting surface 3 of the mounting bracket 1. The configuration of device 20 is not particularly limited, but it may include, for example, monitoring equipment (also called monitoring devices, 20A in Figures 1-3), an adapter for that monitoring equipment (so to speak, an AC power supply, 20A' in Figures 1-3), an uninterruptible power supply (also called an uninterruptible power supply (UPS), 20B' in Figures 2 and 3, there may be multiple), an over voltage ground relay (OVGR, 20C' in Figures 2 and 3), an outlet (grounded type, 20D' in Figures 2 and 3), a terminal block (screw tap type, 20E' in Figures 2 and 3), or a wiring duct (20F' in Figures 2 and 3, there may be multiple). Other devices 20 may include any electrical or electronic equipment, such as circuit breakers, instrument current transformers, instrument voltage transformers, switches, relays other than ground fault voltage relays, resistors, chargers, control equipment (control devices), lightning arresters, fuses, communication equipment, and power distribution equipment. Of these devices 20, the device 20 that is mounted diagonally via the mounting bracket 1 is designated as the monitoring device 20A, and will be explained in detail below.

[0025] The monitoring device 20A is a device used in solar power generation equipment to monitor the amount of electricity from the grid (such as the amount of electricity purchased and sold), as well as other information related to the solar power generation equipment (such as the amount of electricity generated, solar radiation intensity, temperature, and the status of the solar power generation equipment). The specific configuration of the monitoring device 20A is not particularly limited, but it may be a smart logger, a programmable logic controller, a computer, etc. In addition, monitoring device 20A may also control the conversion unit in solar power generation equipment, etc. This conversion unit is a part that converts the direct current from the power generation unit, such as a solar panel (solar cell), into alternating current, and also controls the flow of current between the power generation unit / storage unit and the distribution board / power receiving board, and is also called a power conditioner. The shape of the monitoring device 20A may be a roughly rectangular parallelepiped or a roughly cubic shape (for example, a thick plate), and there are no particular limitations on its size, but the width may be, for example, a lower limit of 160 mm or more, preferably 180 mm or more, more preferably 200 mm or more, or an upper limit of 350 mm or less, preferably 300 mm or less, more preferably 250 mm or less (225 mm, etc.), and the height may be, for example, a lower limit of 100 mm or more, preferably 120 mm or more, more preferably 140 mm or more, or an upper limit of 300 mm or less, preferably 250 mm or less, more preferably 200 mm or less (160 mm, etc.), and the depth may be, for example, a lower limit of 20 mm or more, preferably 30 mm or more, more preferably 40 mm or more, or an upper limit of 110 mm or less, preferably 90 mm or less, more preferably 70 mm or less (44 mm, etc.).

[0026] By arranging such monitoring equipment 20A and other equipment 20 diagonally within the enclosure 10 via the mounting bracket 1, the front-facing space within the enclosure 10 can be effectively utilized, wiring of the equipment 20 is made easier, and QR codes (registered trademarks, especially codes attached to the narrow side end faces) attached to the housing of the equipment 20 can be easily read. In this manner, when the equipment 20 is positioned at an angle, another piece of equipment 20' may be attached to the rear side of the equipment mounting surface 3, either to the box mounting surface 2 or to the rear surface inside the enclosure 10. In this case, the other piece of equipment 20' can be any piece of equipment other than the equipment 20 that is actually positioned at an angle by the mounting fixture 1, for example, it could be an adapter 20A' for the monitoring equipment 20A. Other devices 20', such as this adapter 20A', may be attached to the box mounting surface 2 or the rear surface inside the panel enclosure 10 by a fixing device separate from the mounting fixture 1, or a fixing device may be provided on the front surface of the box mounting surface 2 of the mounting fixture 1 for the attachment of this other device 20'. In this case, the other device 20' may be something other than the adapter 20A' of the monitoring device 20A mentioned above, and may be, for example, an outlet, terminal block, resistor, fuse, etc. Also, when the device 20 is positioned diagonally on a single mounting fixture 1, the number of other devices 20' attached to the rear side of the device mounting surface 3 may be one or multiple.

[0027] <Distance D from the front end of the equipment 20 to the rear end of the box mounting surface 2, front-to-back length L within the panel box body 10> As shown in Figure 1, the distance D from the front end of the equipment 20 to the rear end of the box mounting surface 2 is the distance from point P1 at the front end of the equipment 20 to point P2 at the foot of the perpendicular drawn from point P1 at the front end of the equipment 20 to the rear surface of the box mounting surface 2 (this point is the rear end of the box mounting surface 2), when the equipment 20 is positioned diagonally inside the enclosure 10 via a mounting fixture 1 to which the box mounting surface 2 is attached to the rear surface inside the enclosure 10. Furthermore, as shown in Figure 1, the front-to-back length L within the cabinet body 10 is, <1> The rear side of the interior of the enclosure body 10 (if a circuit board 10c is provided, this will be the front surface of the circuit board 10c; if a circuit board 10c is not provided, this will be the front surface of the rear outer casing). <2> (Similarly,) it means the distance from the front opening edge of the main body 10b of the cabinet body 10, <2> If the enclosure body 10 has a door 10a and the rear surface of the door 10a is recessed forward, then this refers to the distance from the rear surface inside the enclosure body 10 to the rear surface of the door 10a, in other words, it is the "effective depth" of the enclosure body 10. The distance D mentioned above may be shorter than the length L mentioned above, but it may also be approximately the same.

[0028] <Other> The present invention is not limited to the embodiments described above. The individual components of the mounting bracket 1, the enclosure body 10, etc., or the overall structure, shape, dimensions, etc., can be modified as appropriate in accordance with the spirit of the present invention. The angle α of the mounting fixture 1 may be adjustable depending on the size, shape, and configuration of the enclosure 10 and equipment 20 used. The configuration of this angle adjustment part (not shown) may be, for example, a hinge-like member that rotatably joins the long sides that abut the equipment mounting surface 3 and the enclosure mounting surface 2, or a structure in which each wing of this hinge-like member is fixed at a predetermined angle with screws or the like. In addition, for angle adjustment, a mounting fixture 1, which is originally made by bending a single surface member to form a box mounting surface 2 and an equipment mounting surface 3, or a fixing device that is roughly ∠-shaped in side view, can be adjusted after actually using it by pushing or pulling the equipment mounting surface 3 forward with your hand or the like. The enclosure body 10 does not necessarily have a door 10a. In this case, the enclosure body 10 is either open at the front or always closed. If the front of the enclosure body 10 is open, the aforementioned distance D may be longer than the aforementioned front-to-back length L. When the equipment 20 is positioned diagonally within the enclosure 10, it is not necessary for another piece of equipment 20' to be mounted on the rear side of the equipment mounting surface 3. [Industrial applicability]

[0029] The mounting fixtures and enclosures of the present invention can be used for remote control panels, switchboards, connection panels (connection boxes), control panels (control boxes), and other types of enclosures. In addition to enclosures, they can be used for larger distribution boards and power distribution panels, as well as for enclosures and enclosures in buildings such as general residences, offices, factories, shops, office buildings, and condominiums. They can also be used in vehicles such as automobiles, railway vehicles, ships, and airplanes. Furthermore, they can be used for solar power generation equipment regardless of the amount or scale of power generation. In addition to solar power generation equipment, they can be used for enclosures and enclosures in equipment that generates electricity using generators (AC motors, etc.) rotated by wind, hydro, wave, or geothermal power, and can be used both indoors and outdoors.
