Description

Technical Field

[0001] The present invention relates to a fixture for mounting equipment in a switchboard body and a switchboard body having the fixture.

Background Art

[0002] Conventionally, a box body for housing electrical equipment is known (see Patent Document 1). This box body for housing electrical equipment is formed by assembling a plurality of plate members so that five sides other than the front side are closed, and a box body formed by attaching a panel on which electrical equipment is mounted to a back plate, and a door member that is assembled to the box body and opens and closes the front side. The box body for housing electrical equipment includes a panel mounting member attached to the back plate, and the panel can be attached via the panel mounting member. On the panel mounting member, an insertion hole through which a fixing member for fixing the box body to an installation surface behind the back plate can be inserted is provided. By passing the fixing member through the back plate from the insertion hole and fixing it to the installation surface, the back plate can be fixed to the installation surface together with the panel mounting member.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, as described in paragraph 0016 etc. of Patent Document 1, the electrical equipment mounted on the panel 8 is represented by three rectangular parallelepipeds in FIGS. 8 and 9. The length of these three electrical equipment in the front-rear direction (depth direction) is short, and there is a large dead space where no electrical equipment is arranged in the front-rear direction inside the box body. Therefore, the space efficiency inside the box body is poor, and there is a problem that the box body (especially when viewed from the front) becomes large.

[0005] In view of such points, the present invention aims to provide a fixture or a panel box body that realizes "effective use of the space inside the panel" by making the oblique arrangement angle formed by the box mounting surface portion and the device mounting surface portion greater than 0° and less than 90°.

Means for Solving the Problems

[0006] The fixture 1 according to the present invention is a fixture for mounting a device inside a panel box. The fixture has a planar box mounting surface portion 2 mounted inside the panel box and a planar device mounting surface portion 3 for mounting the device. The device mounting surface portion 3 is mounted in an obliquely arranged state on the box mounting surface portion 2, and the first feature is that the oblique arrangement angle α formed by the device mounting surface portion 3 and the box mounting surface portion 2 is greater than 0° and less than 90°.

[0007] The panel box body 10 according to the present invention is a panel box body having the above-described fixture 1 and a device 20. The panel box body is provided with a door 10a that can be opened and closed on the front side, and the box mounting surface portion 2 of the fixture 1 is mounted on the rear surface. The first feature is that when the device 20 is obliquely arranged inside the panel box via the fixture 1, the distance from the front end of the device 20 to the rear end of the box mounting surface portion 2 is shorter than the front-rear length inside the panel box.

[0008] The second feature of the panel box body 10 according to the present invention is that, in addition to the above first feature, in the obliquely arranged state, behind the device mounting surface portion 3, a device 20' different from the obliquely arranged device 20 is mounted on the box mounting surface portion 2 and / or the rear surface inside the panel box.

[0009] Due to these features, by setting the inclined arrangement angle α formed by the equipment mounting surface portion 3 and the box mounting surface portion 2 to be greater than 0° and less than 90°, in Patent Document 1 (the conventional example shown in FIG. 1(a)), since each equipment is arranged substantially parallel to the rear side surface of the panel box body 10, there is a large space where nothing is arranged in front of the equipment with a short front-rear length, which is different from the case where the space inside the panel box could not be effectively utilized. Even if the front-rear length of the equipment 20 is short, as shown in FIG. 1(b), the equipment 20 can be arranged in the front-rear direction within the panel box body 10, improving the space efficiency inside the panel box body 10 ( "effective utilization of the space inside the panel"), and enabling the panel box body 10 (especially when viewed from the front) to be made more compact. In addition, since the present invention obliquely arranges the equipment 20 within the panel box body 10 via the fixture 1, it can also be said to be a structure of "oblique arrangement of equipment within the panel box".

[0010] Also, in the state where the equipment 20 is obliquely arranged within the panel box body 10 via the fixture 1 with the box mounting surface portion 2 attached to the rear surface inside the panel box body 10, by making the distance from the front end of the equipment 20 to the rear end of the box mounting surface portion 2 shorter than the front-rear length within the panel box body 10, while maximizing the "effective utilization of the space inside the panel", the equipment 20 can be housed within the panel box body 10.

[0011] Furthermore, by attaching another equipment 20' to the rear side of the equipment mounting surface portion 3, further "effective utilization of the space inside the panel" can be achieved.

Effects of the Invention

[0012] According to the fixture and the panel box body according to the present invention, by setting the inclined arrangement angle formed by the box mounting surface portion and the equipment mounting surface portion to be greater than 0° and less than 90°, "effective utilization of the space inside the panel" and the like can be realized.

Embodiments for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. <Fixture 1> In FIGS. 1 to 3, a fixture 1 according to the present invention is shown. This fixture 1 is a tool for mounting a device 20, which will be described later, inside a panel box body 10, which will be described later. Through this fixture 1, the device 20 is disposed obliquely inside the panel box body 10. The fixture 1 has a box mounting surface portion 2 and a device mounting surface portion 3, which will be described later. The angle formed by these two surface portions 2 and 3 (the angle between the two surface portions 2 and 3) is an oblique arrangement angle α, which will be described later. In addition, the fixture 1 may have fixing tools (such as screws, bolts, nuts, etc.) used when mounting the fixture 1 on the panel box body 10 or mounting the device 20.

[0015] The material of the fixture 1 is not particularly limited. For example, it can be a metal such as stainless steel (SUS304, etc.), steel, cast iron, aluminum, etc., or it can also be FRP (Fiber Reinforced Plastics), plastic (synthetic resin), rubber (synthetic rubber), wood, stone, etc. In addition, these can be combined (the box mounting surface portion 2 and the device mounting surface portion 3 can be made of the same material or different materials). In the fixture 1, where the device mounting surface portion 3 is mounted in an obliquely arranged state on the box mounting surface portion 2, it is possible to originally bend one surface member to form the box mounting surface portion 2 and the device mounting surface portion 3, or each of the surface portions 2 and 3 can be one surface member, and they can be attached together (by welding, adhesion, or through a fixing tool (not shown) in a substantially ∠ shape in side view or an angle adjustment portion (not shown)) to form the box mounting surface portion 2 and the device mounting surface portion 3.

[0016] <Box mounting surface portion 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 switchboard body 10 described later. In addition, since the equipment mounting surface portion 3 described later is mounted in an obliquely arranged state 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 equipment mounting surface portion 3) of the equipment mounting surface portion 3. For mounting the box mounting surface portion 2 to the switchboard body 10, holes (through holes) for fixtures, recesses, etc. may be formed. 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.

[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 may have 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 equipment mounting surface portion 3.

[0018] <Equipment mounting surface portion 3> As shown in FIGS. 1 to 3, the device mounting surface portion 3 is a part of the above-described fixture 1 and is a planar portion for mounting a device 20 described later. Further, since the device mounting surface portion 3 is mounted in an obliquely arranged state with respect to the above-described box mounting surface portion 2, it can be said that the device mounting surface portion 3 is supported by the box mounting surface portion 2. The device mounting surface portion 3 may also be formed with holes (through holes) for fixtures, recesses, etc. for mounting the device 20. For directly mounting another device 20' described later on the rear surface inside the cabinet body 10, etc., a substantially concave notch corresponding to the size and shape of the other device 20' may be formed. The specific configuration of the device mounting surface portion 3 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 device mounting surface portion 3 will be mainly described as being substantially rectangular with a substantially concave notch.

[0019] The size of the device mounting surface portion 3 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 50 mm or more, preferably 70 mm or more, more preferably 90 mm or more, and an upper limit value of 250 mm or less, preferably 200 mm or less, more preferably 150 mm or less (such as 110 mm). The thickness of the device mounting surface portion 3 is 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 device mounting surface portion 3 may be smaller than, substantially the same as, or larger than the box mounting surface portion 2.

[0020] <Oblique arrangement angle α> As shown in FIG. 1, the inclined arrangement angle α is the angle formed by the above-described equipment mounting surface portion 3 and the box mounting surface portion 2, and in the side view of the fixture 1, it can also be said to be the angle between the equipment mounting surface portion 3 and the box mounting surface portion 2. The inclined arrangement angle α is greater than 0° and less than 90°. The lower limit value can 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 value can be, for example, 85° or less, preferably 80° or less, more preferably 70° or less, and even more preferably 60° or less (such as 30°, 45°, 60°, etc.).

[0021] <Panel box body 10> As shown in FIGS. 1 to 3, the panel box body 10 has, inside thereof (inside the panel box body 10), the equipment 20 described below mounted in an obliquely arranged state via the above-described fixture 1, and the box mounting surface portion 2 of the fixture 1 is to be mounted inside the panel box body 10. For one panel box body 10, the number of fixtures 1 used and the number of equipment 20 arranged obliquely can be one, but a plurality is also acceptable. Inside the panel box body 10 (inside the panel box body 10), in addition to the equipment 20 arranged obliquely, another equipment 20' may be mounted. For one panel box body 10, the number of another equipment 20' to be mounted can also be one or a plurality. The panel box body 10 is not limited to the use as a panel, such as, for example, a panel box of a remote control panel, a changeover panel, a connection panel (connection box), a control panel (control box), etc., depending on the equipment 20 to be mounted inside. Inside such a panel box body 10, in addition to the fixture 1 and the equipment 20, 20', wirings, wiring ducts, wiring fasteners, etc. may be provided, and insertion holes for inserting the wirings inside and outside the panel box body 10 may be provided on the lower surface.

[0022] The panel box body 10 may be provided with a door 10a that can be opened and closed on the front side. That is, in the panel box body 10, the side with the door 10a is the front side, and the opposite side (the back side of the main body 10b of the panel box body 10) is the back side. In the switchboard cabinet 10, the box mounting surface 2 of the fixture 1 is mounted from the inside on the rear side surface (so to speak, the rear surface), and may also be mounted from the inside on the left side surface (left surface), the right side surface (right surface), the upper side surface (upper surface), the lower side surface (lower surface), the rear side surface of the door 10a, etc. of the switchboard cabinet 10. When the fixture 1, the device 20, etc. are mounted from the inside of the switchboard cabinet 10, they may be directly mounted on the exterior of the switchboard cabinet 10 (the members constituting the exterior), but may also be mounted on the substrate (panel, wooden, etc.) 10c mounted from the inside on the exterior (especially the rear side surface, etc.). Also, the door 10a of the switchboard cabinet 10 may be detachable from the main body 10b of the switchboard cabinet 10. As shown in FIG. 3 etc., the door 10a may be a side-opening door, but may also be a double-leaf door (where there are multiple doors 10a for one switchboard cabinet 10 and those multiple doors 10a open left and right), or a vertical-opening door (where the door 10a opens upward). In addition, the switchboard cabinet 10 may have an eaves portion 10d with its upper surface protruding forward.

[0023] The shape of the switchboard cabinet 10 may be a substantially rectangular parallelepiped shape, a substantially cubic shape, etc. Its size is not particularly limited, but the left-right length (width) is, for example, the lower limit value is 200 mm or more, preferably 300 mm or more, more preferably 400 mm or more, and the upper limit value is 1100 mm or less, preferably 900 mm or less, more preferably 700 mm or less (such as 452 mm or 500 mm). Also, the up-down length (height) is, for example, the lower limit value is 200 mm or more, preferably 300 mm or more, more preferably 500 mm or more, and the upper limit value is 1300 mm or less, preferably 1100 mm or less, more preferably 900 mm or less (such as 660 mm or 715 mm). The front-rear length (depth, depth) is, for example, the lower limit value is 110 mm or more, preferably 140 mm or more, more preferably 170 mm or more, and the upper limit value is 400 mm or less, preferably 350 mm or less, more preferably 300 mm or less (such as 209 mm or 250 mm).

[0024] <Device 20, another device 20’> As shown in FIGS. 1 to 3, the device 20 is mounted in the above-described panel box body 10 in an obliquely arranged state via the above-described fixture 1, and the device 20 is to be mounted on the device mounting surface portion 3 of the fixture 1. The configuration of the device 20 is not particularly limited. For example, it may be a monitoring device (also referred to as a monitoring apparatus, 20A in FIGS. 1 to 3), an adapter for the monitoring device (so to speak, an AC power supply, 20A' in FIGS. 1 to 3), an uninterruptible power supply device (also referred to as an uninterruptible power supply (UPS), 20B' in FIGS. 2 and 3, and there may be a plurality), an overvoltage ground relay (OVGR, 20C' in FIGS. 2 and 3), a power outlet (such as a grounded type, 20D' in FIGS. 2 and 3), a terminal block (such as a screw tap type, 20E' in FIGS. 2 and 3), a wiring duct (20F' in FIGS. 2 and 3, and there may be a plurality), or the like. In addition, the device 20 may be any electrical device or electronic device such as a circuit breaker, an instrument current transformer, an instrument voltage transformer, a switch, a relay other than an overvoltage ground relay, a resistor, a charger, a control device (control apparatus), a lightning arrester, a fuse, or other communication devices and power distribution devices. Among these devices 20, taking the device 20 mounted in an obliquely arranged state via the fixture 1 as the monitoring device 20A, it will be detailed below.

[0025] The monitoring device 20A is a device that monitors the amount of power from the system (such as the amount of purchased power and the amount of sold power) in a solar power generation device or the like, or other information related to the solar power generation device (such as the amount of power generation, solar radiation intensity, temperature, and the state of the solar power generation device). The specific configuration of the monitoring device 20A is not particularly limited. For example, it may be a smart logger, a sequencer, a computer, or the like. In addition, the monitoring device 20A may control a conversion unit or the like in a solar power generation device or the like. Note that this conversion unit is a part that converts the DC current from a power generation unit such as a solar panel (solar cell) into an AC current and also controls the flow of current between the power generation unit and the power storage unit and between the power distribution board and the incoming and outgoing power distribution board. It can also be said to be a power conditioner. The shape of the monitoring device 20A may be substantially rectangular parallelepiped or substantially cubic (for example, thick plate-like), etc., and its size is not particularly limited. However, the left-right length (width) has a lower limit value of, for example, 160 mm or more, preferably 180 mm or more, more preferably 200 mm or more, and an upper limit value of 350 mm or less, preferably 300 mm or less, more preferably 250 mm or less (such as 225 mm). In addition, the up-down length (height) has a lower limit value of, for example, 100 mm or more, preferably 120 mm or more, more preferably 140 mm or more, and an upper limit value of 300 mm or less, preferably 250 mm or less, more preferably 200 mm or less (such as 160 mm). The front-back length (depth, depth) has a lower limit value of, for example, 20 mm or more, preferably 30 mm or more, more preferably 40 mm or more, and an upper limit value of 110 mm or less, preferably 90 mm or less, more preferably 70 mm or less (such as 44 mm).

[0026] By arranging the device 20 such as the monitoring device 20A obliquely in the switchboard box body 10 via the fixture 1, the front-side in-board space in the front-back direction (depth direction) within the switchboard box body 10 can be effectively utilized, the wiring of the device 20 is facilitated, and it becomes easier to read the QR code (registered trademark, especially the code attached to the narrow end face on the side) etc. attached to the housing of the device 20. In this way, in the state where the device 20 is arranged obliquely, another device 20' different from the device 20 may be attached to the box attachment surface portion 2 or the rear surface within the switchboard box body 10 on the rear side of the device attachment surface portion 3 of the device 20. In this case, the other device 20' may be any device as long as it is other than the device 20 actually arranged obliquely by the fixture 1. For example, it may be the adapter 20A' etc. of the monitoring device 20A. Another device 20' such as this adapter 20A' may be attached to the box attachment surface portion 2 or the rear surface within the switchboard box body 10 by a fixture different from the fixture 1, but a fixture may be provided on the front surface of the box attachment surface portion 2 of the fixture 1 for attaching this other device 20'. Furthermore, another device 20' in this case may be other than the adapter 20A' of the monitoring device 20A described above, and for example, it may be an outlet, a terminal block, a resistor, a fuse, or the like. Also, in a state where the device 20 is disposed obliquely by one fixture 1, the number of another devices 20' attached to the rear side of the device attachment surface portion 3 may be one or plural.

[0027] <Distance D from the front end of the device 20 to the rear end of the box attachment surface portion 2, front-rear length L in the cabinet body 10> As shown in FIG. 1, the distance D from the front end of the device 20 to the rear end of the box attachment surface portion 2 means that, via the fixture 1 to which the box attachment surface portion 2 is attached to the rear surface in the cabinet body 10, in a state where the device 20 is disposed obliquely in the cabinet body 10, from the point P1 at the front end of the device 20 to the point P2 at the foot of the perpendicular dropped to the rear surface of the box attachment surface portion 2 (this becomes the point at the rear end of the box attachment surface portion 2). Also, as shown in FIG. 1, the front-rear length L in the cabinet body 10 means <1> from the rear surface inside the cabinet body 10 (if the substrate 10c is provided, it is the front surface of the substrate 10c, and if the substrate 10c is not provided, it is the front surface of the exterior on the rear side. The same applies to <2>) to the front opening edge of the main body 10b of the cabinet body 10, or <2> when the cabinet body 10 has a door 10a and the rear surface of the door 10a is recessed forward, it means the distance from the rear surface inside the cabinet body 10 to the rear surface of the door 10a. In other words, it is the "effective depth" in the cabinet body 10. The above-described distance D may be shorter than the above-described front-rear length L, or may be substantially the same.

[0028] <Others> The present invention is not limited to the above-described embodiments. Each configuration or the overall structure, shape, dimensions, etc. of the fixture 1, the cabinet body 10, etc. can be appropriately changed in accordance with the gist of the present invention. The inclined arrangement angle α in the fixture 1 may be adjustable according to the size, shape, configuration, etc. of the panel box body 10 and the device 20 to be 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 between the device mounting surface part 3 and the box mounting surface part 2, or a structure that fixes each blade part of this hinge-like member at a predetermined angle with a screw or the like. In addition, as the angle adjustment part, the fixture 1 originally formed by bending one face member into the box mounting surface part 2 and the device mounting surface part 3, or a fixing tool that is substantially ∠-shaped in side view, may be adjusted by pressing the device mounting surface part 3 with a hand or pulling it forward after actual use. The panel box body 10 may not be provided with the door 10a. In this case, the front side of the panel box body 10 is either open or always in a closed state. In addition, when the front side of the panel box body 10 is open, the above-mentioned distance D may be longer than the above-mentioned front-back length L. When the device 20 is disposed obliquely in the panel box body 10, another device 20' may not be mounted on the rear side of the device mounting surface part 3.

Industrial Applicability

[0029] The fixture and the panel box body of the present invention can be used for the panel box body of a remote control panel, or for any panel box body such as a changeover panel, a connection panel (connection box), a control panel (control box), etc. In addition, in addition to the panel box body, it can be used for a panel housing such as a larger distribution board or a power receiving and distribution board, or for a panel box body or panel housing in a building such as a general house, an office, a factory, a store, a building, a condominium, etc., or for a vehicle such as an automobile, a railway vehicle, a ship, an airplane, etc. It may also be used for a solar power generation device regardless of its power generation amount and scale. In addition to the solar power generation device, it can also be used for a panel box body or panel housing in a device that generates electricity by a generator (such as an AC motor) rotated by wind power, hydraulic power, wave power, geothermal heat, etc., and can be used indoors or outdoors.
