Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in Patent Document 1, the attachment members are attached to the framework in a state where the framework is attached to the side wall, and the operator attaching the electrical devices has to attach the electrical devices or perform wiring work inside the narrow box body. Therefore, there is a problem that the efficiency of work such as attaching and wiring the electrical devices is poor.

[0006] In view of the above circumstances, an object of the present invention is to provide an equipment box capable of improving the workability of attaching electrical devices and wiring the electrical devices.

Means for Solving the Problems

[0007] To achieve the above objective, an equipment box according to one embodiment of the present invention comprises a housing, a plurality of electrical devices, a support member, a first wiring group, a second wiring group, and a relay connector. The above-mentioned electrical devices are connected to an external power supply by wiring. The support member described above supports the multiple electrical devices and is housed in the enclosure described above. The first set of wiring described above is connected to the external power supply. The second set of wiring described above is connected to the multiple electrical devices described above. The above-mentioned relay connector electrically connects the first wiring group and the second wiring group.

[0008] In the above-described equipment enclosure, multiple electrical devices are powered from a first group of wires connected to an external power source via a relay connector and a second group of wires. This eliminates the need to individually wire each electrical device while the support member, to which the multiple electrical devices are mounted, is placed inside the enclosure. In other words, the multiple electrical devices and the second group of wires can be connected before the support member is installed inside the enclosure, and when the support member is housed inside the enclosure, power is supplied to the multiple electrical devices by connecting the first group of wires to the relay connector. This improves the workability of electrical device installation and wiring, as it eliminates the need to work inside the enclosure when mounting electrical devices to the support member and eliminates the need to individually wire each electrical device from the external power source inside the enclosure.

[0009] The first wiring group described above comprises a plurality of first wires, each having a plurality of first terminals on the other end and one end connected to the external power supply, and a connector portion that commonly supports the plurality of first terminals. The second wiring group described above has a plurality of second wires, each having a plurality of second terminals on the other end, with one end connected to the plurality of electrical devices. The above-mentioned relay connector may have a first connection portion to which the connector portion is connected, and a second connection portion to which the plurality of second terminals are connected and which is electrically connected to the connector portion.

[0010] The first wiring group described above further comprises a cylindrical wiring protection material that bundles the plurality of first wirings, and the cylindrical wiring protection material may have overlapping portions in the radial direction where the wiring protection material overlaps.

[0011] The above wiring protection material may also be a self-wrapping tube.

[0012] The wiring protection material may further be provided with fixing members for securing it to the housing or the support member.

[0013] The above-mentioned enclosure may have a rectangular annular main frame body and a plurality of subframe members intersecting each side of the main frame body.

[0014] The above-mentioned support member comprises a plurality of column frames arranged parallel to each other with a predetermined gap between them, and a plurality of support frames connecting the plurality of column frames. The above-mentioned electrical equipment may be mounted on the above-mentioned support frames.

[0015] The support member comprises a plate-shaped support plate on which the plurality of electrical devices are supported, a plurality of curtain rail sections provided parallel to each other with a predetermined gap between them and attached to the housing, and a plurality of fasteners provided on the plurality of curtain rail sections and movable along the plurality of curtain rail sections. The support plate may have multiple connecting holes for connecting to the multiple curtain rail sections by the multiple fasteners.

[0016] The above equipment box may also be installed in a railway vehicle. [Effects of the Invention]

[0017] As described above, the present invention makes it possible to improve the workability of installing and wiring electrical equipment. [Brief explanation of the drawing]

Figure 8 is a perspective view of the main frame 11. Figure 9 is a perspective view of the first main frame 11A and the second main frame 11B. In the following figures, the X axis, Y axis and Z axis directions are three mutually orthogonal axes.

[0020] In this embodiment, the equipment box 1000 is installed under the floor (not shown) of a railway vehicle, and as shown in Figures 1 to 4, the equipment box 1000 comprises a housing device 1, a plurality of electrical devices 54A to 54C, a first wiring group (external wiring) 90, and a second wiring group (internal wiring) 53. The housing device 1 comprises a frame (casing) 10A, a plate portion 20, a door portion 30, a bottom portion 40, a mounting member 50, and a third connecting member 60. In this embodiment, the housing device 1 is a cube with a length of approximately 1m in the Y-axis direction, approximately 0.7m in the X-axis direction, and approximately 0.8m in the Z-axis direction, but is not limited to these dimensions. Furthermore, the undercarriage of a railway vehicle is the part of the vehicle's casing that is exposed to the outside and faces the ground, and the equipment box 1000 is suspended (hanging) so as to face the ground.

[0021] In this embodiment, the direction of travel of the railway vehicle is defined as the Y-axis direction, the width direction of the vehicle is defined as the X-axis direction, and the height direction of the vehicle is defined as the Z-axis direction.

[0022] The undercarriage (not shown) of the railway vehicle is located on the positive Z-axis side when viewed from the storage device 1, and the storage device 1 is mounted under that undercarriage. The storage device 1 is configured to accommodate various electrical equipment depending on the type and number of the railway vehicle. Furthermore, two storage devices 1 can be placed side by side in the X-axis direction on a single vehicle. In this embodiment, they are arranged in a way that the cylindrical portion 90, which will be described later, is not exposed, but of course, this is not the only option.

[0023] [Bottom part] In this embodiment, as shown in Figures 2-5, the bottom surface 40 has planes parallel to the X-axis and Y-axis directions. In this embodiment, the bottom surface 40 is rectangular with its shorter side in the X-axis direction and its longer side in the Y-axis direction, but it is not limited to this, and may be rectangular with its longer side in the X-axis direction and its shorter side in the Y-axis direction, or it may be square. In this embodiment, the bottom surface 40 is made of iron, but it is not limited to this, and may be made of stainless steel (SUS), for example, or not limited to metal, but may be made of resin.

[0024] [Itabe] In this embodiment, as shown in Figures 1 to 4, the plate portion 20 has an upper portion 21 that faces the bottom portion 40 and connects to the frame 10 (described later), and a plurality of side portions 22, 23 that are parallel to the XZ plane (second plane) perpendicular to the Y axis and face each other, and connect to the frame 10. In this embodiment, the plate portion 20 is made of iron, but of course it is not limited to this and may be made of stainless steel (SUS), for example, or not limited to metal, but may be made of resin.

[0025] (Top part) The upper surface portion 21 has an upper surface 210 that is parallel to the XY plane and faces the lower surface portion 40. In this embodiment, the upper surface 210 is rectangular in shape with its shorter side in the X-axis direction and its longer side in the Y-axis direction, but it is not limited to this, and may be rectangular in shape with its longer side in the X-axis direction and its shorter side in the Y-axis direction, or it may be square. In this embodiment, the thickness of the upper surface 210 in the Z-axis direction is approximately 1.6 mm, but it is not limited to this.

[0026] The upper portion 21 has suspension fittings 211 to 214 for mounting the housing device 1 under the floor of a railway vehicle located on the positive Z-axis side. In this embodiment, the suspension fittings 211 to 214 are provided at the four corners of the rectangular upper portion 21 (see Figures 1 to 3). The suspension fittings 211 to 214 are connected to the upper portion 21 by bolts B and nuts N (see Figure 7). The bolts B pass through and connect not only the suspension fittings 211 to 214 and the upper portion 21, but also the suspension fittings 211 to 214, the upper portion 21, and the frame 10.

[0027] Furthermore, the top surface portion 21 has top surface bends 215 that extend in the negative direction of the Z axis from the four sides of the top surface 210. When viewed from the Z axis direction, the top surface bends 215 have a "□" shape and are located outside the size of the outer frame before the top surface portion 21 is fitted in (the state in which the bottom surface portion 40, the frame 10, and the multiple side portions 22, 23 are combined, see Figure 3) (when viewed from the Z axis direction). In other words, when the top surface portion 21 is assembled, when viewed from the Z axis direction, the top surface bends 215 are located on the outermost side of the multiple side portions 22, 23, the front portion 13, and the rear portion 14 (see Figures 1 and 2).

[0028] Furthermore, as shown in Figures 2 and 3, the upper surface portion 21 has a plurality of upper surface connecting holes 21A through which bolts B pass. In this embodiment, the arrangement of the plurality of upper surface connecting holes 21A is such that the bolts B connect the upper surface portion 21 to the frame 10 (passing through in the Z-axis direction), and is provided at positions where a plurality of subframes 12A, 12B, 12D, 12E (described later) of the frame 10 are provided when viewed from the Z-axis direction.

[0029] In this embodiment, four upper connecting holes 21A are provided along the X-axis direction and arranged in four parallel rows, but this is by no means limited to this configuration.

[0030] (side part) The multiple side portions 22 and 23 are parallel to the XZ plane (second plane) perpendicular to the Y-axis direction, face each other, and connect to the frame 10. In this embodiment, the thickness of the first side portion 220 and the second side portion 230 (described later) in the Y-axis direction is approximately 1.6 mm, but is not limited to this.

[0031] (First side section) The first side portion 22 has a first side portion 220 which is a plane parallel to the XZ plane, and is connected to the right side of the frame 10 when viewed from the front portion 13 side, which will be described later (see Figures 1-4).

[0032] Furthermore, the first side portion 22 has a first side bend portion 221 that extends in the negative direction of the Y axis from three sides of the first side portion 220. These three sides consist of one side parallel to the X axis direction and on the bottom portion 40 side, and two sides parallel to the Z axis direction, forming a "U" shape when viewed from the Y axis direction (see Figures 2-4).

[0033] When viewed from the Y-axis direction, the first side folded portion 221 is located outside the size of the outer frame before the first side portion 22 is fitted (when the bottom portion 40 and the frame structure 10 are assembled, see Figure 4). In other words, when the first side portion 22 is assembled, when viewed from the Y-axis direction, the first side folded portion 221 is located on the outermost side of the front portion 13, rear portion 14, and frame structure 10 (see Figures 1-3).

[0034] As shown in Figures 2-4, the first side surface 220 has a plurality of first side connecting holes 22A through which the first connecting member T penetrates the first side surface 22. In this embodiment, the arrangement of the plurality of first side connecting holes 22A is such that the first connecting member T connects the first side surface 22 to the frame 10 (penetrating in the Y-axis direction), and is provided at positions where the plurality of subframes 12A, 12F, 12H of the frame 10 are connected to the second main frame 11C when viewed from the Y-axis direction, or at positions where the second main frame 11C is not located on the plurality of subframes 12A, 12F, 12H when viewed from the Y-axis direction (see Figures 6 and 7).

[0035] In this embodiment, the multiple first side connecting holes 22A are arranged in a row of five along the X-axis direction, and three sets of these five holes are arranged along the Z-axis direction. Of course, this is not the only option; for example, three holes may be arranged in a row along the X-axis direction.

[0036] Furthermore, as shown in Figures 1 to 5, the first side surface 220 is connected to the front folded portion 130A (described later) of the front portion 13 and the rear folded portion 140A of the rear portion 14 by the first connecting member T via the first side connecting hole 22A.

[0037] (Second side section) The second side portion 23 has a second side portion 230 which is a plane parallel to the XZ plane, and is connected to the left side of the frame 10 when viewed from the front portion 13 side, which will be described later (see Figures 3 and 4).

[0038] Furthermore, the second side portion 23 has a second side bend portion 231 that extends in the positive direction of the Y axis from three sides of the second side portion 230. These three sides consist of one side parallel to the X axis direction and on the bottom portion 40 side, and two sides parallel to the Z axis direction, forming a "U" shape when viewed from the Y axis direction.

[0039] When viewed from the Y-axis direction, the second side folded portion 231 is located outside the size of the outer frame before the second side portion 23 is fitted (when the bottom portion 40 and the frame structure 10 are assembled, see Figure 4). In other words, when the second side portion 23 is assembled, when viewed from the Y-axis direction, the second side folded portion 231 is located on the outermost side of the front portion 13, rear portion 14, and frame structure 10 (see Figures 3 and 4).

[0040] As shown in Figure 4, the second side surface 230 has a plurality of second connecting holes 23A through which the first connecting member T penetrates the second side surface 23. In this embodiment, the plurality of second side connecting holes 23A are arranged such that the first connecting member T connects the second side surface 23 to the frame 10 (penetrating in the Y-axis direction), and are located at positions where the plurality of subframes 12E, 12G, 12J of the frame 10 are connected to the second main frame 11E when viewed from the Y-axis direction, or at positions on the plurality of subframes 12E, 12G, 12I where the second main frame 11E is not located when viewed from the Y-axis direction (see Figures 6 and 7).

[0041] In this embodiment, the multiple first side connecting holes 22A are arranged in a row of five along the X-axis direction, and three sets of these five holes are arranged along the Z-axis direction. Of course, this is not the only option; for example, three holes may be arranged in a row along the X-axis direction.

[0042] Furthermore, similar to the first side portion 22, the second side portion 230 is connected to the front folded portion 130A (described later) of the front portion 13 and the rear folded portion 140A of the rear portion 14 by the first connecting member T via the second side connecting hole 23A.

[0043] In this embodiment, the first side surface 220 and the second side surface 230 were approximately square in shape, but are not limited to this, and may be rectangular in shape with the shorter side in the X-axis direction and the longer side in the Y-axis direction.

[0044] [Framework structure] The frame structure 10 includes a frame body (housing) 10A (described later), a front portion 13 and a rear portion 14 attached to the frame body (housing) 10A, and engagement mechanisms M1 to M4. The frame structure 10 is formed in a grid pattern.

[0045] The frame structure 10A has a rectangular annular main frame body 11 that is parallel to the YZ plane (first plane) perpendicular to the X-axis direction, and a plurality of subframes (a plurality of subframe materials) 12A to 12J that extend along the X-axis direction, are arranged parallel to each other, and connect (intersect) with the main frame body 11, and is provided on the bottom surface portion 40. The main frame body 11 is rectangular when viewed from the X-axis direction. The plurality of subframes (a plurality of subframe materials) 12A to 12J are "L" shaped (see Figures 3 to 9). In this embodiment, the frame structure 10 is formed from iron, but of course it is not limited to this, and may be made of stainless steel (SUS), for example, or not limited to metal, but may be made of resin.

[0046] The frame structure 10 further includes a front portion 13 which is parallel to the YZ plane and fixed (intersecting) to one end of a plurality of subframes 12A to 12J, and has first opening ends 131, 132 of first openings 131', 132' into which mounting members 50 can be inserted, and a rear portion 14 which is parallel to the YZ plane and fixed to the other end of a plurality of subframes 12A to 12J, and has second opening ends 141, 142 of second openings 141', 142' into which mounting members 50 can be inserted (see Figures 2 to 5).

[0047] Here, "intersection" is not limited to a state where things are perpendicular to each other (like a cross), but also refers to a state where things overlap in a T-shape.

[0048] (Mainframe) The main frame body 11 includes a plurality of first main frames (a plurality of first frame parts) 11A, 11B that extend along the Y-axis direction and are arranged parallel to each other, and a plurality of second main frames (a plurality of second frame parts) 11C to 11E that extend along the Z-axis direction and are arranged parallel to each other, and are connected to both ends of the plurality of first main frames 11A, 11B by a second connecting member 70, which will be described later.

[0049] (First mainframe) The first main frame 11A has a first main frame surface 111A provided on the upper surface 21 side and parallel to the XY plane, a plurality of first main bending portions 112A extending in the negative direction of the Z axis from both sides along the Y axis of the first main frame surface 111A, and a first engaging portion 115A that engages with the subframes 12B to 12D described later (see Figures 7 to 9).

[0050] The first main frame 11A has a plurality of first main connecting holes 113A on the first main frame surface 111A. The plurality of first main connecting holes 113A are provided at locations corresponding to the first sub-connecting holes 123A to 123E of the plurality of subframes 12A to 12E.

[0051] In other words, when viewed from the Z-axis direction, a portion of the first sub-connecting holes 123A to 123E is positioned at the locations where the multiple first main connecting holes 113A are provided. The third connecting member 60 then passes through the first sub-connecting holes 123A to 123E and through the multiple first main connecting holes 113A. In other words, the multiple first connecting holes 113A and a portion of the first sub-connecting holes 123A to 123E are each aligned in a straight line in the Z-axis direction.

[0052] Furthermore, the first main frame 11A has multiple first bending connection holes 114A in multiple first main bending sections 112A. The multiple first bending connection holes 114A are through holes for connecting to the second main frames 11C~11E, which will be described later, by the second connecting member 70. The multiple first bending connection holes 114A are formed to penetrate in the direction of the X axis, and in this embodiment, six of them are provided on the positive X-axis side of the multiple first main bending sections 112A.

[0053] In other words, two are provided at each of the three locations (one end on the positive Z-axis side) where the second main frame 11C~11E connects (see Figure 8). Of the multiple first main bending sections 112A, multiple first bending connection holes 114A are also provided on the negative X-axis side, similar to the positive X-axis side, and are provided so as to penetrate when viewed from the X-axis direction.

[0054] Furthermore, the first engaging portion 115A engages with (accompanies) a first recess 124B (described later) having a plurality of first opposing surfaces 1241B provided on the subframe 12B. In this embodiment, the first engaging portion 115A has a "U" shape with a first main frame surface 111A and a plurality of first main bent portions 112A, and is provided in the first intersection region W1 where the subframe 12B and the first main frame A intersect. However, it is not limited to this, and the first engaging portion 115A may have a notch in the Z-axis direction, into which a part of the first recess 124B (described later) may be inserted.

[0055] Furthermore, the first engaging portion 115A is not limited to the subframe 12B described above, and the subframes 12C and 12D also have the same configuration as the subframe 12B.

[0056] The first main frame 11B has a first main frame surface 111B provided on the bottom surface 40 side and parallel to the XY plane, a plurality of first main folding portions 112B extending in the positive direction of the Z axis from both sides along the Y axis of the first main frame surface 111B, and a first engaging portion 115B that engages with the subframe 12I described later (see Figure 8).

[0057] Furthermore, the first main frame 11B has multiple first bending connection holes 113B in multiple first main bending sections 112B. The multiple first bending connection holes 113B are through holes for connecting to the second main frames 11C to 11E, which will be described later, by the second connecting member 70. The multiple first bending connection holes 113B are formed to penetrate in the X-axis direction, and in this embodiment, two are provided on the positive X-axis side of the multiple first main bending sections 112B, and these are provided at three locations (one end on the negative Z-axis side) corresponding to the second main frames 11C to 11E (see Figure 8). In addition, multiple first bending connection holes 113B are provided on the negative X-axis side of the multiple first main bending sections 112B, similar to the positive X-axis side, and are provided to penetrate when viewed from the X-axis direction.

[0058] Furthermore, the first engaging portion 115B is similar to the first engaging portion 115A and engages with a first recess (not shown) having a plurality of first opposing surfaces (not shown) provided on the subframe 12I. In this embodiment, the first engaging portion 115B has a "U" shape with a first main frame surface 111B and a plurality of first main bent portions 112B. However, it is not limited to this, and the first engaging portion 115B may have a notch in the Z-axis direction, into which a part of the first recess described later may be inserted.

[0059] As shown in Figure 8, the first main frame 11A and the first main frame 11B are U-shaped with their openings facing each other.

[0060] In this embodiment, the first main frames 11A and 11B were U-shaped, but of course, they are not limited to this and may have other shapes.

[0061] (Second mainframe) The second main frame 11C is provided to connect one end of the first main frame 11A and the first main frame 11B on the positive Y-axis side. The second main frame 11C is provided on the first side portion 22 side and has a "U" shape with a second main frame surface 111C parallel to the XZ plane, a plurality of second main bend portions 112C extending in the negative Y-axis direction from both sides of the second main frame surface 111C along the Z-axis direction, and a first engagement portion 117C that engages with the subframe 12F, which will be described later.

[0062] The second mainframe 11C is located inside the U-shaped structure of the first mainframes 11A and 11B. In other words, the size (width) of the opening in the X-axis direction of the first mainframes 11A and 11B is larger than the size (width) of the second mainframe 11C in the X-axis direction (see Figures 7-9).

[0063] The second main frame 11C also has a plurality of second main connecting holes 113C and a plurality of second main corresponding holes 113C' on the second main frame surface 111C. The plurality of second main connecting holes 113C are provided at locations corresponding to the second sub-connecting holes 124A, 123F, and 121H of the plurality of sub-frames 12A, 12F, and 12H. The plurality of second main corresponding holes 113C' are provided at locations corresponding to some of the plurality of first side connecting holes 22A described above (see Figures 1, 2, and 8).

[0064] In other words, when viewed from the Y-axis direction, multiple second sub-connecting holes 124A, 123F, and 121H are arranged at the locations where multiple second main connecting holes 113C are provided. The third connecting member 60 passes through the second sub-connecting holes 124A, 123F, and 121H and then through the multiple second main connecting holes 113C. In other words, the second sub-connecting holes 124A, 123F, and 121H and the multiple second main connecting holes 113C are each arranged in a straight line in the Y-axis direction.

[0065] Furthermore, when viewed from the Y-axis direction, multiple first side connecting holes 22A are arranged at the positions where multiple second main corresponding holes 113C' are provided. The first connecting member T passes through the first side connecting holes 22A and through the multiple second main corresponding holes 113C'. In other words, the first side connecting holes 22A and the multiple second main corresponding holes 113C' are arranged in a straight line in the Y-axis direction.

[0066] In this embodiment, the multiple second main connecting holes 113C are provided in two locations along the X-axis direction on the positive Z-axis side of the second main frame 11C, and the second main corresponding hole 113C' is provided in one location below the two second main connecting holes 113C (negative Z-axis direction). These three holes are provided in three locations along the Z-axis direction.

[0067] The second main frame 11C also has multiple second bending connection holes 114C in multiple second main bending sections 112C. The multiple second bending connection holes 114C are through holes for connecting the first main frames 11A and 11B with the second connecting member 70. The multiple second bending connection holes 114C are formed to penetrate in the X-axis direction, and in this embodiment, two are provided on the positive X-axis side of the multiple second main bending sections 112C, corresponding to the two locations of the first main frames 11A and 11B (see Figure 8). The multiple second bending connection holes 114C are also provided on the negative X-axis side of the multiple second main bending sections 112C, similar to the positive X-axis side, and are provided to penetrate when viewed from the X-axis direction.

[0068] Furthermore, the first engaging portion 117C engages with a first recess 124F provided on the subframe 12F, which has a plurality of first opposing surfaces 1241F. In this embodiment, the first engaging portion 117C has a "U" shape with a second main frame surface 111C and a plurality of second main bent portions 112C. However, it is not limited to this, and the first engaging portion 117C may have a notch in the Y-axis direction, into which a part of the first recess 124F, described later, may be inserted.

[0069] The second main frame 11E is provided to connect one end of the first main frame 11A and the first main frame 11B on the negative side of the Y axis. The second main frame 11E is provided on the second side portion 23 side and has a "U" shape with a second main frame surface 111E parallel to the XZ plane, a plurality of second main bend portions 112E extending in the positive direction of the Y axis from both sides of the second main frame surface 111E along the Z axis direction, and a first engagement portion 117E that engages with the subframe 12G, which will be described later.

[0070] The second mainframe 11E is located inside the U-shaped structure of the first mainframes 11A and 11B. In other words, the size (width) of the opening in the X-axis direction of the first mainframes 11A and 11B is larger than the size (width) of the second mainframe 11E in the X-axis direction.

[0071] The second main frame 11E also has a plurality of second main connecting holes 113E and a plurality of second main corresponding holes (not shown) on the second main frame surface 111E. The plurality of second main connecting holes 113E are provided at locations corresponding to the second sub-connecting holes (not shown) of the plurality of sub-frames 12E, 12G, and 12J. The plurality of second main corresponding holes (not shown) are similar to the plurality of second main corresponding holes 113C' described above and are provided at locations corresponding to some of the plurality of second side connecting holes 23A described above.

[0072] In other words, when viewed from the Y-axis direction, multiple second sub-connecting holes (not shown) are arranged at the positions where multiple second main connecting holes 113E are provided. The third connecting member 60 passes through the second sub-connecting holes (not shown) and then through the multiple second main connecting holes 113E. The multiple second main connecting holes 113C and the multiple second main connecting holes 113E are arranged in a straight line in the Y-axis direction.

[0073] The second main frame 11E also has multiple second bending connection holes 114E in multiple second main bending sections 112E. The multiple second bending connection holes 114E are through holes for connecting the first main frames 11A and 11B described above with the second connecting member 70. The multiple second bending connection holes 114E are formed to penetrate in the X-axis direction, and in this embodiment, two are provided on the positive X-axis side of the multiple second main bending sections 112E, corresponding to the two locations on each of the first main frames 11A and 11B (see Figure 8). The multiple second bending connection holes 114E are also provided on the negative X-axis side of the multiple second main bending sections 112E, similar to the positive X-axis side, and are provided to penetrate when viewed from the X-axis direction.

[0074] Furthermore, the first engaging portion 117E engages with a first recess (not shown) having a plurality of opposing surfaces (not shown) provided on the subframe 12G, similar to the first engaging portion 117C. In this embodiment, the first engaging portion 117E has a "U" shape with a second main frame surface 111E and a plurality of second main bent portions 112E. However, it is not limited to this, and the first engaging portion 117E may have a notch in the Y-axis direction, into which a part of the first recess, described later, may be inserted.

[0075] The second main frame 11D is provided in the central portion of the first main frames 11A and 11B in the Y-axis direction. The second main frame 11D has a "U" shape, having a second main frame surface 111D parallel to the XZ plane, and a plurality of second main bent portions 112D extending in the negative direction of the Y-axis from both sides of the second main frame surface 111D along the Z-axis direction. In this embodiment, the opening of the second main frame 11D faces the negative direction of the Y-axis, but of course it is not limited to this, and may face the positive direction of the Y-axis.

[0076] The second mainframe 11D is located inside the U-shaped structure of the first mainframes 11A and 11B. In other words, the size (width) of the opening in the X-axis direction of the first mainframes 11A and 11B is larger than the size (width) of the second mainframe 11D in the X-axis direction.

[0077] The second main frame 11D also has multiple second bending connection holes 113D in multiple second main bending sections 112D. The multiple second bending connection holes 113D are through holes for connecting the first main frames 11A and 11B described above with the second connecting member 70. The multiple second bending connection holes 113D are formed to penetrate in the X-axis direction, and in this embodiment, two are provided on the positive X-axis side of the multiple second main bending sections 112D, corresponding to the two locations on each of the first main frames 11A and 11B (see Figure 8). The multiple second bending connection holes 113D are also provided on the negative X-axis side of the multiple second main bending sections 112D, similar to the positive X-axis side, and are provided to penetrate when viewed from the X-axis direction.

[0078] In this embodiment, the subframe extending in the X-axis direction does not intersect (connect) with the second main frame 11D, but the subframe may intersect (connect) with the second main frame 11D. In that case, a configuration similar to that of the first engaging portions 117C and 117E may be provided.

[0079] Furthermore, the second main frames 11C, 11D, and 11E have mounting member connecting holes 115C, 116C, 115D, 116D, 115E, and 116E for fixing the mounting support member 50D (described later) with a rear fastener 50C (described later) (see Figures 3 and 8).

[0080] The mounting member connecting holes 115C, 115D, and 115E are arranged in a straight line along the Y-axis when viewed from the X-axis direction. The mounting member connecting holes 116C, 116D, and 116E are arranged on the negative Z-axis side of the mounting member connecting holes 115C, 115D, and 115E, and are arranged in a straight line along the Y-axis when viewed from the X-axis direction.

[0081] The method of connecting the first main frames 11A, 11B and the second main frames 11C, 11D, 11E may involve not only the second connecting member 70, but also fillet welding at the points connected by the second connecting member 70. This can suppress rattling of the main frame 11.

[0082] In this embodiment, the second main frames 11C, 11D, and 11E were U-shaped, but of course, they are not limited to this and may have other shapes.

[0083] (Subframe) Multiple subframes 12A to 12J extend along the X-axis direction, are arranged parallel to each other, and intersect each side of the main frame body 11 with the front portion 13 and the rear portion 14 (see Figures 5 to 7). Specifically, the multiple subframes 12A to 12J engage with the main frame body 11 at their intermediate portions in the X-axis direction and are fixed by a third connecting member 60 and welding. The multiple subframes 12A to 12J also engage with the front portion 13 and the rear portion 14 and are fixed by welding. Furthermore, the multiple subframes 12A to 12J are arranged (connected) along the entire circumference (outer periphery) of the main frame body 11 when viewed from the X-axis direction. Here, the entire circumference of the main frame body 11 is formed by the first main frame surfaces 111A and 111B and the second main frame surfaces 111C and 111E. In other words, the multiple subframes 12A to 12J are arranged in a rectangular ring shape when viewed from the X-axis direction.

[0084] The subframe 12A has an "L" shape, comprising a first subframe surface 121A parallel to the XY plane, and a second subframe surface 122A extending in the negative direction of the Z axis from one side of the first subframe surface 121A along the X-axis direction (the positive Y-axis side). The subframe 12A is provided at one end of the first main frame 11A on the positive Y-axis side. In this embodiment, the subframe 12A is connected to the main frame 11 at approximately the central portion (intermediate portion) AO (in the X-axis direction).

[0085] The subframe 12A has a plurality of first sub-connecting holes 123A in the first subframe surface 121A for connecting to the upper surface 21 by bolts B. The plurality of first sub-connecting holes 123A also serve as through holes for connecting the first subframe surface 121A to the first main frame 11A by a third connecting member 60. Nuts N are provided on the negative Z-axis side of the first subframe surface 121A, and the aforementioned bolts B are fitted into them.

[0086] Multiple first sub-connecting holes 123A are provided along the X-axis direction. The multiple first sub-connecting holes 123A provided at the locations where the subframe 12A and the first main frame 11A are connected are provided so as to be penetrated by the third connecting member 60 in the Z-axis direction, as described above. In this embodiment, there are a total of six first sub-connecting holes 123A, two at each end in the X-axis direction and two at the locations where they connect to the first main frame 11A, but the number is not particularly limited and may be four or eight.

[0087] The subframe 12A has a plurality of second sub-connecting holes 124A for connecting to the second mainframe 11C on the second subframe surface 122A by a third connecting member 60, and a plurality of second sub-corresponding holes 125A provided in locations corresponding to some of the plurality of first side connecting holes 22A described above.

[0088] The multiple second sub-connecting holes 124A and multiple second main connecting holes 113C, located at the points where the subframe 12A and the second main frame 11C connect (the central portion of the subframe 12A in the X-axis direction and one end of the second main frame 11C on the positive Z-axis side), are provided so as described above that they are penetrated by the third connecting member 60 in the Y-axis direction. In this embodiment, two of the multiple second sub-connecting holes 124A are provided at positions that overlap with the second main frame surface 111C when viewed from the Y-axis direction. Of course, this is not the only option, and the number of holes may be just one.

[0089] Furthermore, when viewed from the Y-axis direction, multiple first side connecting holes 22A are arranged at the positions where multiple second sub-corresponding holes 125A are provided. The first connecting member T passes through the first side connecting holes 22A and through the multiple second sub-corresponding holes 125A. In other words, the first side connecting holes 22A and the second sub-corresponding holes 125A are arranged in a straight line in the Y-axis direction. In this embodiment, three second sub-corresponding holes 125A are provided along the X-axis direction. As shown in Figure 7, these three holes are located in the positive and negative directions of the X-axis, centered around a hole that overlaps with the second main corresponding hole 113C' when viewed from the Y-axis direction.

[0090] In this embodiment, the multiple second sub-connecting holes 124A are provided in pairs along the X-axis direction on the positive Z-axis side of the second subframe surface 122A, and the second corresponding second sub-hole 125A is provided below the two second sub-connecting holes 124A (in the negative Z-axis direction).

[0091] Furthermore, the multiple second sub-connecting holes 124A and the multiple second main connecting holes 113C described above are used as temporary fastening holes between the subframe 12A and the main frame 11. This is because the main frame 11 and the subframe 12 need to be fixed in advance in order to connect them to the plate portion 20, the front portion 13, and the rear portion 14, which will be described later. In this embodiment, for example, the two second sub-connecting holes 124A and the second main connecting holes 113C may be fixed in advance with bolts and nuts or rivets for temporary fastening.

[0092] Alternatively, the areas where the subframe 12A and the first main frame 11A and the second main frame 11C come into contact may be welded (fillet welded). This makes it possible to suppress rattling when the subframe 12A and the first main frame 11A and the second main frame 11C are fixed together.

[0093] The subframe 12A has a first engaging portion 126A that engages with the front folded portion 130A, which will be described later, and a second engaging portion 127A that engages with the rear folded portion 140A, which will be described later.

[0094] The first engaging portion 126A engages with the first recess 1300A, which is located on the positive X-axis side of the subframe 12A and is formed in the front bent portion 130A, which will be described later. The first engaging portion 126A is L-shaped when viewed from the X-axis direction, and the first recess 1300A formed in the front bent portion 130A is L-shaped, similar to the first engaging portion 126A, when viewed from the X-axis direction.

[0095] Furthermore, the second engaging portion 127A engages with a second recess 1400A formed in the rear bent portion 140A, which is located on the negative X-axis side of the subframe 12A and will be described later. The second engaging portion 127A is L-shaped when viewed from the X-axis direction, and the second recess 1400A formed in the rear bent portion 140A is L-shaped, similar to the second engaging portion 127A, when viewed from the X-axis direction.

[0096] The front folded portion 130A and the first engaging portion 126A are flush with the XY plane and the XZ plane. Similarly, the rear folded portion 140A and the second engaging portion 127A are flush with the XY plane and the XZ plane.

[0097] Subframe 12E has a configuration almost identical to subframe 12A described above, differing in that subframe 12E is located at one end of the first main frame 11A on the negative side of the Y-axis. Subframe 12H also has a configuration almost identical to subframe 12A described above, differing in that subframe 12H is located at one end of the first main frame 11B on the positive side of the Y-axis. Furthermore, subframe 12J has a configuration almost identical to subframe 12A described above, differing in that subframe 12J is located at one end of the first main frame 11B on the negative side of the Y-axis.

[0098] Subframe 12B has an "L" shape, comprising a first subframe surface 121B parallel to the XY plane, and a second subframe surface 122B extending in the negative direction of the Z axis from one side of the first subframe surface 121B along the X axis (the positive Y axis side). Subframe 12B is provided on the negative Y axis side of subframe 12A.

[0099] The subframe 12B has a plurality of first sub-connecting holes 123B for connecting to the upper surface portion 21 by bolts B on the first subframe surface 121B, or to the first main frame 11A by a third connecting member 60. Nuts N are provided on the negative Z-axis side of the first subframe surface 121B, and the bolts B described above are fitted into them.

[0100] Multiple first sub-connecting holes 123B are provided along the X-axis direction. The multiple first sub-connecting holes 123B provided at the locations where the subframe 12B and the first main frame 11A are connected are provided so as to be penetrated by the third connecting member 60 in the Z-axis direction, as described above. In this embodiment, there are a total of six first sub-connecting holes 123B, two at each end in the X-axis direction and two at the locations where they connect to the first main frame 11A, but the number is not particularly limited and may be four or eight.

[0101] The second subframe surface 122B has a U-shaped recess (first recess) 124B. The recess 124B is formed at the same position in the X-axis direction as the first sub-connecting hole 123B of the central portion (intermediate portion) BO, and has a plurality of first opposing surfaces 1241B facing each other in the X-axis direction. The subframe 12B also has first engaging portions 125B and second engaging portions 126B at both ends in the X-axis direction, which engage with the front portion 13 and rear portion 14, which will be described later.

[0102] The first engaging portion 125B engages with a first recess (second recess) 1300A formed in the front bent portion 130A, which will be described later, and is located on the positive X-axis side of the subframe 12B. The second engaging portion 126B engages with a second recess 1400A formed in the rear bent portion 140A, which will be described later, and is located on the negative X-axis side of the subframe 12B.

[0103] The first engaging portion 125B is formed to be shorter than the second subframe surface 122B when viewed from the Z-axis direction (in the X-axis direction). In other words, when viewed from the Y-axis direction, one end of the subframe 12B in the positive X-axis direction has a portion where only the second subframe surface 122B is formed. The second subframe surface 122B has a first extension portion 1221B which is provided on the positive X-axis side (front bent portion 130A side or front portion 13 side) of the first subframe surface 121B when viewed from the Y-axis direction. The first extension portion 1221B abuts (contacts) the front bent portion 130A and the front portion 130. The first extension portion 1221B also has a first notch portion 125B' cut toward the negative Z-axis direction. The role of the first notch portion 125B' is to provide relief for sheet metal bending. In other words, the notch is designed to prevent the sheet metal (frame) from being pulled and becoming convex outwards when bending the subframe 12B.

[0104] The second engaging portion 126B is formed to be shorter than the second subframe surface 122B when viewed from the Z-axis direction (in the X-axis direction). In other words, when viewed from the Y-axis direction, one end of the subframe 12B in the negative X-axis direction has a portion where only the second subframe surface 122B is formed. The second subframe surface 122B has a second extension portion 1222B which is provided on the negative X-axis side (towards the rear bent portion 140A or the rear portion 14) of the first subframe surface 121B when viewed from the Y-axis direction. The second extension portion 1222B abuts (contacts) the rear bent portion 140A and the front surface 140. The second extension portion 1222B also has a second notch portion (not shown) similar to the first notch portion 125B' which is cut toward the negative Z-axis direction.

[0105] The front folded portion 130A and the first engaging portion 125B are flush with the XY plane and the XZ plane. Similarly, the rear folded portion 140A and the second engaging portion 126B are flush with the XY plane and the XZ plane.

[0106] The areas where the first engaging portion 125B and the first extension portion 1221B come into contact with the front portion 13 (the front bent portion 130A and the front portion 130) may be welded (fillet welded). This makes it possible to suppress rattling when the subframe 12B and the front portion 13 are fixed together.

[0107] Alternatively, the areas where the second engaging portion 126B and the second extension portion 1222B come into contact with the rear portion 14 (rear bent portion 140A and rear portion 140) may be welded (fillet welded). This makes it possible to suppress rattling when the subframe 12B and the rear portion 14 are fixed together.

[0108] Furthermore, in this embodiment, the multiple opposing surfaces 1241B of the recess 124B face (contact) the multiple first main bent portions 112A.

[0109] Furthermore, the area where the recess 124B and the first main frame 11A come into contact may be welded (fillet welded). This allows for positioning when connecting the upper surface portion 21. It also helps to suppress rattling when the subframe 12B and the first main frame 11A are fixed together.

[0110] Subframe 12C has a configuration almost identical to subframe 12B described above, differing in that subframe 12C is located in the central part of the Y-axis of the first mainframe 11A. Subframe 12D has a configuration almost identical to subframe 12B described above, differing in that subframe 12D is located on the negative side of the Y-axis of the first mainframe 11A. Furthermore, subframe 12I has a configuration almost identical to subframe 12B described above, differing in that subframe 12I is located approximately in the central part of the Y-axis of the first mainframe 11B.

[0111] The subframe 12F has an "L" shape, comprising a first subframe surface 121F parallel to the XY plane, and a second subframe surface 122F extending in the negative direction of the Z axis from one side of the first subframe surface 121F along the X axis (the negative side of the Y axis). The subframe 12F is located in the approximately central part of the Z axis of the second mainframe 11C.

[0112] The subframe 12F is provided in the central part in the X-axis direction and has a plurality of first sub-connecting holes 123F for connecting to the second main frame 11C by a third connecting member 60 on the second subframe surface 122F, and a plurality of second sub-corresponding holes 127F provided in locations corresponding to some of the plurality of first side connecting holes 22A described above.

[0113] The multiple first sub-connecting holes 123F and the multiple second main connecting holes 113C, which are provided at the locations where the subframe 12F and the second main frame 11C are connected (the central portion in the X-axis direction of the subframe 12F and the central portion in the Z-axis direction of the second main frame 11C), are provided so as to be penetrated by the third connecting member 60 in the Y-axis direction, as described above. In this embodiment, two of the multiple first sub-connecting holes 123F are provided at the locations where they are connected to the first main frame 11A.

[0114] Furthermore, when viewed from the Y-axis direction, multiple first side connecting holes 22A are arranged at the positions where multiple second sub-corresponding holes 127F are provided. The first connecting member T passes through the first side connecting holes 22A and through the multiple second sub-corresponding holes 127F. In other words, the first side connecting holes 22A and the second sub-corresponding holes 127F are arranged in a straight line in the Y-axis direction. In this embodiment, three second sub-corresponding holes 127F are provided along the X-axis direction. As shown in Figure 7, these three holes are located in the positive and negative directions of the X-axis, centered around a hole that overlaps with the second main corresponding hole 113C' when viewed from the Y-axis direction.

[0115] In this embodiment, the multiple second sub-connecting holes 123F are provided in pairs along the X-axis direction on the positive Z-axis side of the second subframe surface 122F, and the second corresponding second sub-hole 127F is provided below the two second sub-connecting holes 123F (in the negative Z-axis direction).

[0116] Furthermore, the multiple second sub-connecting holes 123F and the multiple second main connecting holes 113C described above are used as temporary fastening holes between the subframe 12F and the main frame 11. This is because the main frame 11 and the subframe 12 need to be fixed in advance in order to connect them to the plate portion 20, the front portion 13, and the rear portion 14, which will be described later. In this embodiment, for example, the two second sub-connecting holes 123F and the second main connecting holes 113C may be fixed in advance with bolts and nuts or rivets for temporary fastening.

[0117] The first subframe surface 121F has a U-shaped recess 124F. The recess 124F is formed at the same position in the X-axis direction as the second subconnecting hole 123F of the central portion FO, and has multiple first opposing surfaces 1241F facing each other in the X-axis direction, and engages with the second main frame 11C. The subframe 12F also has first engaging portions 125F and second engaging portions 126F at both ends in the X-axis direction, and is connected to the front portion 13 and rear portion 14, which will be described later, by interlocking grooves.

[0118] The first engaging portion 125F engages with a first recess 1300A formed in the front bent portion 130A, which will be described later, and is located on the positive X-axis side of the subframe 12F. The second engaging portion 126F engages with a second recess 1400A formed in the rear bent portion 140, which will be described later, and is located on the negative X-axis side of the subframe 12A.

[0119] The first engaging portion 125F is formed to be shorter than the first subframe surface 121F when viewed from the Y-axis direction (in the X-axis direction). In other words, when viewed from the Z-axis direction, one end of the subframe 12F in the positive X-axis direction has a portion where only the first subframe surface 121F is formed. The first subframe surface 121F has a first extension portion 1211F which is provided on the positive X-axis side (front bent portion 130A side or front portion 13 side) of the second subframe surface 122F when viewed from the Z-axis direction. The first extension portion 1211F abuts (contacts) the front bent portion 130A and the front portion 130. The first extension portion 1211F also has a first notch portion 125F' cut toward the negative Y-axis direction. The role of the first notch portion 125F' is to provide relief for sheet metal bending. In other words, the notch is designed to prevent the sheet metal (frame) from being pulled and becoming convex outwards when bending subframe 12F.

[0120] The second engaging portion 126F is formed to be shorter than the first subframe surface 121F when viewed from the Z-axis direction (in the X-axis direction). When viewed from the Z-axis direction, one end of the subframe 12F in the negative direction of the X-axis has a portion where only the first subframe surface 121F is formed. The first subframe surface 121F has a second extension portion 1212F which is provided on the negative direction side of the X-axis (towards the rear bent portion 140A or the rear portion 14) than the second subframe surface 122F when viewed from the Z-axis direction. The second extension portion 1212F abuts (contacts) the rear bent portion 140A and the rear surface 140. The second extension portion 1212F also has a second notch portion 126F' similar to the first notch portion 125F' which is cut toward the negative direction side of the Y-axis.

[0121] The front folded portion 130A and the first engaging portion 125F (second subframe surface 122F) are flush with the XZ plane. Similarly, the rear folded portion 140A and the second engaging portion 126F (second subframe surface 122F) are flush with the XZ plane.

[0122] Furthermore, in this embodiment, the multiple opposing surfaces 1241F of the recess 124F face (contact) the multiple second main bent portions 112C.

[0123] The areas where the first engaging portion 125F and the first extension portion 1211F come into contact with the front portion 13 (the front bent portion 130A and the front portion 130) may be welded (fillet welded). This allows for positioning when connecting the upper portion 21. It also suppresses rattling when the subframe 12F and the front portion 13 are fixed together.

[0124] Alternatively, the areas where the second engaging portion 126F and the second extension portion 1212F come into contact with the rear portion 14 (rear bent portion 140A and rear portion 140) may be welded (fillet welded). This allows for positioning when connecting the upper portion 21. It also helps to suppress rattling when the subframe 12F and the rear portion 14 are fixed together.

[0125] Furthermore, the area where the recess 124F and the second main frame 11C come into contact may be welded (fillet welded). This allows for positioning when connecting the second side portion 22. It also helps to suppress rattling when the subframe 12F and the second main frame 11C are fixed together.

[0126] Subframe 12G has a configuration almost identical to subframe 12F described above, but differs in that it is located in the approximately central part of the Y-axis of the second mainframe 11E.

[0127] As described above, the frame structure 10 is formed by a main frame 11 parallel to the YZ plane and a plurality of subframes 12A to 12J extending in the X-axis direction, so the strength of the housing device 1 can be ensured by the frame structure 10.

[0128] In this embodiment, subframes 12A to 12J are L-shaped, but are not limited to this and may have other shapes. Also, the number of subframes is not limited to 10 as in this embodiment. Furthermore, the arrangement of subframes 12A to 12J is not limited to this embodiment.

[0129] (Front part) The front part 13 is parallel to the YZ plane and has a front surface 130 fixed to one end on the positive X-axis side of the plurality of sub-frames 12A to 12J, and first opening ends 131 and 132 provided on the front surface 130 (see FIGS. 1 to 5). In the present embodiment, the front part 13 has a rectangular shape that is short in the Z-axis direction and long in the Y-axis direction. Of course, it is not limited to this, and it may have a rectangular shape that is long in the Z-axis direction and short in the Y-axis direction, or a square shape.

[0130] The front surface 130 has a front bending part 130A extending in the negative X-axis direction from the four sides of the front surface 130. The front bending part 130A has a plurality of first front bending surfaces 130B extending along the Y-axis direction and a plurality of second front bending surfaces 130C extending along the Z-axis direction, and has a "mouth" shape when viewed from the X-axis direction.

In the present embodiment, three bending corresponding holes 130A' are provided along the Z-axis direction. Of course, it is not limited to this, and there may be four or more, or two or less. Also, the plurality of bending corresponding holes 130A' are not provided in a straight line with the sub-frames 12A, 12F, 12H in the X-axis direction. Of course, they may be provided on the same straight line. The same configuration applies to the plurality of sub-frames 12E, 12G, 12I side.

[0132] Furthermore, the multiple first front bent surfaces 130B of the front bent portion 130A have first recesses (second recesses) 1300A that engage with the subframes 12A to 12E and 12H to 12J described above. Furthermore, the multiple second front bent surfaces 130C of the front bent portion 130A have first recesses (second recesses) 1300B that engage with the subframes 12A, 12E, 12F, 12G, 12H, and 12J described above.

The first recess 1300A that engages with subframes 12B, 12C, 12D, and 12I has a plurality of second opposing surfaces 1301A that face each other in the Y-axis direction. Of course, although not shown, subframes 12C, 12D, 12E, 12H, 12I, and 12J also engage with the first recess 1300A in the same way.

[0134] The first recess 1300B engages with the first engaging portion 126A of subframe 12A and the first engaging portion 125F of subframe 12F. The first recess 1300B that engages with subframes 12F and 12G has a plurality of second opposing surfaces 1301B that face each other in the Z-axis direction. Of course, although not shown, subframes 12E, 12G, 12H, and 12J also engage with the first recess 1300B in the same way.

[0135] The first recesses 1300A and 1300B, which engage with the first engaging portion 126A of subframe 12A, are cut in an "L" shape when viewed from the X-axis direction. Similarly, the first recesses 1300A and 1300B, which engage with the first engaging portion (not shown) of subframes 12E, 12H, and 12J, are cut in an "L" shape when viewed from the X-axis direction.

Similarly, the first recess 1300A, which engages with the first engaging portion (not shown) of subframes 12C, 12D, and 12I, is cut in a "U" shape when viewed from the Z-axis direction.

[0137] The first recess 1300B, which engages with the first engaging portion 125F of the subframe 12F, is cut in a "U" shape when viewed from the Y-axis direction. Similarly, the first recess 1300B, which engages with the first engaging portion (not shown) of the subframe 12G, is cut in a "U" shape when viewed from the Y-axis direction.

[0138] The first recesses 1300A and 1300B are formed to engage with the multiple subframes 12A to 12J and be parallel (flush) to the XY and XZ planes. This eliminates the gap between the multiple subframes 12A to 12J and the plate portion 20 when the upper portion 21, the first side portion 22, and the second side portion 23 are connected.

[0139] The first open end 131 is provided on the positive Y-axis side and, when viewed from the X-axis direction, has a rectangular opening 131', with the shorter side in the Z-axis direction and the longer side in the Y-axis direction. Of course, it is not limited to this, and it may also be a rectangle with the longer side in the Z-axis direction and the shorter side in the Y-axis direction, or it may be a square.

[0140] The first open end 131 has a projection 131A that protrudes from the front surface 130 (opening 131') in the positive direction of the X axis, a flange portion 131B provided on the projection 131A and parallel to the YZ plane, and a contact portion 131C that extends from the negative direction side of the X axis to the negative direction side of the Z axis of the projection 131A and is formed along the Y axis direction (see Figures 1-5, 10, and 11).

[0141] The projection 131A is a rectangular annular shape provided along the opening 131', and the flange portion 131B is formed to extend outward from the projection 131A (outside the opening 131').

[0142] The second opening end 132 is similar to the first opening end 131, and is located on the negative side of the Y-axis. When viewed from the X-axis direction, it has a rectangular annular opening and is rectangular in shape with the shorter side in the Z-axis direction and the longer side in the Y-axis direction. Of course, it is not limited to this, and may be rectangular in shape with the longer side in the Z-axis direction and the shorter side in the Y-axis direction, or it may be square in shape.

[0143] The second open end 132 has a projection 132A that protrudes from the front surface 130 (opening 132') in the positive direction of the X axis, a flange portion 132B provided on the projection 132A and parallel to the YZ plane, and a contact portion (not shown) provided on the negative direction side of the projection 132A in the X axis direction and extending in the Y axis direction.

[0144] The projection 132A is a rectangular annular shape provided along the opening 132', and the flange portion 132B is formed to extend outward from the projection 132A (outside the opening 132').

[0145] In this embodiment, the front portion 13 has a first open end 131 and a second open end 132, but is not limited to this; it may have either one or three or more.

[0146] The front section 13 has a plurality of wiring holes 133 that penetrate in the X-axis direction (see Figures 2 to 5). The plurality of wiring holes 133 are holes for passing external wiring 90 when supplying power from an external source to the electrical equipment 54. The number and size of the plurality of wiring holes 133 can be changed as appropriate.

[0147] Furthermore, the front portion 13 has a plurality of hinge portions 134 between the first open end portion 131 and the plurality of wiring holes 133 in the Z-axis direction.

[0148] In this embodiment, two hinges 134 are provided along the Y-axis, and the door portion 30, described later, is configured to rotate around the Y-axis. In other words, the door portion 30 can be opened in the positive direction of the Z-axis. Of course, this is not the only configuration, and three or more hinges 134 may be provided.

[0149] The plurality of hinge portions 134 include a connection plate 134A connected to the door portion 30, and a rotation support portion 134B fixed to the front surface portion 13 and rotatably supporting the connection plate 134A.

[0150] (Rear surface portion) Regarding the rear surface portion 14, it has the same configuration as the front surface portion 13. The rear surface portion 14 is parallel to the YZ plane and has a rear surface 140 fixed to one end on the negative X-axis side of the plurality of sub-frames 12A to 12J, and a second opening end provided on the rear surface 14A (see FIGS. 1 to 5). In this embodiment, the rear surface 140 has a rectangular shape with a short side in the Z-axis direction and a long side in the Y-axis direction.

[0151] The rear surface 140 has a rear surface bending portion 140A extending in the negative X-axis direction from the four sides of the rear surface 140. The rear surface bending portion 140A has a plurality of first rear surface bending surfaces 140B extending along the Y-axis direction and a plurality of second rear surface bending surfaces 140C extending along the Z-axis direction, and has a "mouth" shape when viewed from the X-axis direction.

[0152] The rear surface bending portion 140A has a plurality of bending corresponding holes 140A' that are connected to a part of the plurality of first side surface connection holes 22A described above. The plurality of bending corresponding holes 140A' are provided on the plurality of second rear surface bending surfaces 140C of the rear surface bending portion 140A where the plurality of sub-frames 12A, 12F, 12H and the rear surface portion 14 are connected. In this embodiment, three bending corresponding holes 140A' are provided along the Z-axis direction. Of course, it is not limited to this, and there may be four or more, or two or less. Also, the plurality of bending corresponding holes 140A' are not provided in a straight line with the sub-frames 12A, 12F, 12H in the X-axis direction. Of course, they may be provided on the same straight line. The same configuration applies to the plurality of sub-frames 12E, 12G, 12I side.

[0153] Furthermore, the multiple first rear bent surfaces 140B of the rear bent portion 140A have second recesses (third recesses) 1400A that engage with the subframes 12A to 12E and 12H to 12J described above. Furthermore, the multiple second rear bent surfaces 140C of the rear bent portion 140A have second recesses (third recesses) 1400B that engage with the subframes 12A, 12E, 12F, 12G, 12H, and 12J described above.

[0154] As shown in Figures 5 and 7, the second recess 1400A engages with the second engaging portion 127A of subframe 12A, the second engaging portion 126B of subframe 12B, and the second engaging portion 125C of subframe 12C. The second recess 1400A that engages with subframes 12B, 12C, 12D, and 12I has a plurality of third opposing surfaces 1401A that face each other in the Y-axis direction. Of course, although not shown, subframes 12D, 12E, 12H, 12I, and 12J also engage with the second recess 1400A in the same way.

[0155] The second recess 1400B engages with the second engaging portion 127A of subframe 12A and the second engaging portion 126F of subframe 12F. The second recess 1400B that engages with subframes 12F and 12G has a plurality of third opposing surfaces 1401B that face each other in the Z-axis direction. Of course, although not shown, subframes 12E, 12G, 12H, and 12J also engage with the second recess 1400B in the same way.

[0156] The second recesses 1400A and 1400B, which engage with the second engaging portion 127A of subframe 12A, are cut in an "L" shape when viewed from the X-axis direction. Similarly, the second recesses 1400A and 1400B, which engage with the second engaging portion (not shown) of subframes 12E, 12H, and 12J, are cut in an "L" shape when viewed from the X-axis direction.

[0157] The second recess 1400A, which engages with the second engaging portion 126B of subframe 12B and the second engaging portion 125C of subframe 12C, is cut in a "U" shape when viewed from the Z-axis direction. Similarly, the second recess 1400A, which engages with the second engaging portion (not shown) of subframe 12D and subframe 12I, is cut in a "U" shape when viewed from the Z-axis direction.

[0158] The second recess 1400B, which engages with the second engaging portion 126F of the subframe 12F in a concave-concave pattern, is cut in a "U" shape when viewed from the Y-axis direction. Similarly, the second recess 1400A, which engages with the second engaging portion (not shown) of the subframe 12G in a concave-concave pattern, is cut in a "U" shape when viewed from the Y-axis direction.

[0159] The second recesses 1400A and 1400B are formed to engage with the multiple subframes 12A to 12J and be parallel (flush) to the XY and XZ planes. This eliminates the gap between the multiple subframes 12A to 12J and the plate portion 20 when the upper portion 21, the first side portion 22, and the second side portion 23 are connected.

[0160] The third open end 141 is provided on the positive Y-axis side and, when viewed from the X-axis direction, has a rectangular opening 141', with the shorter side in the Z-axis direction and the longer side in the Y-axis direction. Of course, it is not limited to this, and it may also be a rectangle with the longer side in the Z-axis direction and the shorter side in the Y-axis direction, or it may be a square.

[0161] The third open end 141, similar to the first open end 131 described above, has a protruding portion (not shown) that projects in the positive direction of the X axis from the rear surface 140 (opening 141'), a flange portion (not shown) provided on the protruding portion and parallel to the YZ plane, and a contact portion (not shown) that extends from the positive direction side of the X axis to the negative direction side of the Z axis of the protruding portion and is formed along the Y axis direction.

[0162] [Engagement mechanism] The engagement mechanism positions the main frame body 11, the front portion 13 and rear portion 14, and the multiple subframes 12A to 12J around the Z axis at any multiple intersection regions where the main frame body 11, the front portion 13 and rear portion 14, and the multiple subframes 12A to 12J intersect.

[0163] Here, "any multiple locations" refers to multiple points where the main frame body 11 intersects with the front section 13 and rear section 14, and the multiple subframes 12A to 12J, and may be any of these locations. Also, positioning around the Z-axis means that movement (rotation) around the Z-axis is restricted.

[0164] The multiple intersection regions include multiple first intersection regions W1 where multiple subframes 12B to 12D and 12I intersect with each of the first mainframes 11A and 11B (multiple first frame sections), and multiple second intersection regions W2 where multiple subframes 12F and 12G intersect with each of the second mainframes 11C and 11D (multiple second frame sections).

[0165] Furthermore, the multiple intersection regions include multiple third intersection regions W3 where the front portion 13 (third frame material) intersects with multiple subframes 12B to 12D and 12I, and multiple fourth intersection regions W4 where the rear portion 14 (fourth frame portion) intersects with multiple subframes 12B to 12D and 12I.

[0166] The engagement mechanism has a first engagement mechanism M1 that positions the first main frames 11A, 11B and subframes 12B~12D, 12I around the Z axis at any multiple locations among the multiple first intersection regions W1.

[0167] The first engagement mechanism M1 includes a recess 124B provided in the intermediate portion BO of the subframe 12B and having a plurality of first opposing surfaces 1241B facing each other in the X-axis direction, and a first engagement portion 115A provided in the first main frame 11A that engages with the recess 124B. Of course, this is not limited to the subframe 12B, but the same applies to the subframes 12C, 12D, and 12I.

[0168] In other words, even if the subframe 12B attempts to move (rotate) around the Z-axis due to the first engagement mechanism M1, the movement (rotation) is restricted by the multiple first main bends 112A of the first main frame 11A (the recesses 124B catch on the multiple first main bends 112A). As a result, the subframe 12B and the first main frame 11A are positioned around the Z-axis. Of course, this is not limited to the subframe 12B, but the same applies to the subframes 12C, 12D, and 12I.

[0169] The engagement mechanism has a second engagement mechanism M2 that positions the second main frames 11C, 11D and subframes 12F, 12G around the Z-axis at any multiple locations among the multiple second intersection regions M2.

[0170] The second engagement mechanism M2 includes a recess 124F provided in the intermediate portion FO of the subframe 12F and having a plurality of first opposing surfaces 1241F facing each other in the X-axis direction, and a second engagement portion 117C provided in the second main frame 11C that engages with the recess 124F. Of course, this is not limited to the subframe 12F, but the same applies to the subframe 12G.

[0171] In other words, even if the subframe 12F attempts to move (rotate) around the Z-axis due to the first engagement mechanism M2, the movement (rotation) is restricted by the multiple second main bending portions 112C of the second main frame 11C (the recess 124F catches on the multiple second main bending portions 112C). As a result, the subframe 12F and the second main frame 11C are positioned around the Z-axis. Of course, this is not limited to the subframe 12F, but the same applies to the subframe 12G.

[0172] The engagement mechanism has a third engagement mechanism M3 that positions the front portion 13 and the subframes 12B-12D and 12I around the Z axis at any multiple locations among a plurality of third intersection regions W3 where the front portion 13 and the subframes 12B-12D and 12I intersect.

[0173] The third engagement mechanism M3 includes a first recess 1300A having a plurality of second opposing surfaces 1301A facing each other in the Y-axis direction, provided on a plurality of first front bent surfaces 130B of the front portion 13, and a second engagement portion 125B provided on the subframe 12B that engages with the second recess 1300A. Of course, this is not limited to the subframe 12B, but the same applies to subframes 12C, 12D, and 12I.

[0174] In other words, even if the subframe 12B attempts to move (rotate) around the Z-axis due to the third engagement mechanism M3, the movement (rotation) is restricted by the first recess 1300A of the first front folded surface 130B (the second engagement portion 125B catches on the multiple second opposing surfaces 1301A of the first recess 1300A). As a result, the subframe 12B and the front portion 13 are positioned around the Z-axis. Of course, this is not limited to the subframe 12B, but the same applies to the subframes 12C, 12D, and 12I.

[0175] The engagement mechanism has a fourth engagement mechanism M4 that positions the rear surface portion 14 and the subframes 12B-12D and 12I around the Z axis at any multiple locations among a plurality of fourth intersection regions W4 where the rear surface portion 14 and the subframes 12B-12D and 12I intersect.

[0176] The fourth engagement mechanism M4 includes a second recess 1400B having a plurality of third opposing surfaces 1401B facing each other in the Y-axis direction, provided on a plurality of first rear folded surfaces 140B of the rear surface portion 14, and a second engagement portion 126B provided on the subframe 12B and engaging with the second recess 1400B. Of course, this is not limited to the subframe 12B, but the same applies to subframes 12C, 12D, and 12I.

[0177] In other words, even if the subframe 12B attempts to move (rotate) around the Z-axis due to the fourth engagement mechanism M4, the movement (rotation) is restricted by the second recess 1400A of the first rear folded surface 140B (the second engagement portion 126B catches on the multiple third opposing surfaces 1401A of the second recess 1400A). As a result, the subframe 12B and the rear portion 14 are positioned around the Z-axis. Of course, this is not limited to the subframe 12B, but the same applies to the subframes 12C, 12D, and 12I.

[0178] [Door section] Figure 10 is a perspective view of the door section 30, Figure 11 is a cross-sectional view of the door section 30, and Figure 12 is a cross-sectional view of the elastic member 80. As shown in Figure 1, the door section 30 has a first door section 30A and a second door section 30B on the front section 13 side. In this embodiment, the length of the door section 30 in the Y-axis direction is approximately 600 mm, but is not limited to this.

[0179] As shown in Figures 1, 10, and 11, the first door portion 30A has a door surface 31A parallel to the YZ plane, door folding portions 32A extending in the negative direction of the X axis from the four sides of the door surface 31A, and a handle portion 33A provided on the door surface 31A. In this embodiment, the first door portion 30A is made of iron, but of course it is not limited to this and may be made of stainless steel (SUS), for example, or not limited to metal but may be made of resin.

[0180] The door surface 31A is rectangular in shape, with its shorter side in the Z-axis direction and its longer side in the Y-axis direction. The fastening fitting 33A is rotatable around its center in the X-axis direction. The fastening fitting 33A has a hook portion 331A provided on the inside of the first door portion 30A (on the negative side of the X-axis relative to the door surface 31A). Furthermore, the shape of the door surface 31A is not limited to the above; it may be rectangular in shape, with its longer side in the Z-axis direction and its shorter side in the Y-axis direction, or it may be square in shape.

[0181] When closing the first door section 30A, the closed state can be maintained by rotating the fastening fitting 33A while the elastic member 80 (described later) is pressed against the flange 131B, causing the hook portion 331A to come into contact (pressure) with the contact portion 131C.

[0182] [Elastic material] The elastic member 80 is annular in shape and is attached to the first door portion 30A. It is a sealing material that abuts against the first opening end 131 when the door is closed. In this embodiment, the elastic member 80 is formed of a packing, but it is not limited to this.

[0183] The elastic member 80 is provided in a rectangular ring shape on the inside of the door surface 31A of the first door portion 30A (on the negative X-axis side with respect to the door surface 31A). Here, the elastic member 80 is formed in a continuous manner, meaning that multiple elastic members are bonded or combined to form a rectangular ring shape. Of course, it is not limited to this, and the elastic member 80 may be formed as a single, seamless, and integral piece.

[0184] As shown in Figure 12, the elastic member 80 has a bottom portion 81 and a bulge portion 82. The bottom portion 81 is provided in a rectangular annular shape along the flange portion 131B and is bonded to the door surface 31A. The bulge portion 82 is provided on the bottom portion 81 and bulges out on the negative side of the X axis.

[0185] As described above, when closing the first door portion 30A, the bulging portion 82 is compressed toward the positive direction of the X-axis, thereby creating a sealed state for the first door portion 30A. As shown in Figure 12, there is no hollow space in the cross-section of the elastic member 80, but a hollow space may be provided in the bulging portion 82, for example. And of course, it is not limited to this, and the cross-sectional shape of the elastic member 80 as viewed from the Y-axis direction may be rectangular or square (without a convex shape).

[0186] [Mounting components] Figure 13 is a perspective view of the mounting member 50, and Figure 14 is a perspective view of the support member 50A. Figure 15 is a perspective view of the fastener 50C, Figure 16 is a perspective view showing how to install the fastener 50C, and Figure 17 is an enlarged view of the fastener 50C and the support member 50A.

[0187] The mounting member 50 includes a support member 50A that supports multiple electrical devices 54A, 54B, and 54C connected to an external power supply by wiring, and a relay connector 50B provided on the support member 50A for supplying power output from the external power supply to each of the multiple electrical devices 54A, 54B, and 54C. The mounting member 50 is fixed to the frame 10 via a mounting support member 50D and fasteners 50C. In this embodiment, the mounting member 50 is formed of an aluminum frame.

[0188] (Support member) The support member 50A has a plurality of column frames 51 that are parallel to each other and have a predetermined gap between them, and a plurality of support frames 52 that are parallel to each other and have a predetermined gap between them, and a plurality of electrical devices 54A, 54B, and 54C are mounted on the YZ plane of the plurality of support frames 52, or mounted across the plurality of support frames 52, giving it a three-dimensional shape. In this embodiment, the support member 50A is an aluminum frame. The predetermined gap is not particularly limited, but for example, it could be a few centimeters, a dozen centimeters, or several tens of centimeters.

[0189] As shown in Figures 13 and 14, the multiple column frames 51 include a first column frame 51A that extends along the Z-axis direction and has a surface parallel to the XZ-plane, and a second column frame 51B that extends along the Z-axis direction and has a surface parallel to the XZ-plane, and is opposite in the Y-axis direction.

[0190] As shown in Figures 13 and 14, the multiple support frames 52 are provided to connect the first column frame 51A and the second column frame 51B, and are U-shaped frames with openings in the negative direction of the Y-axis. Starting from the positive direction of the Z-axis, they consist of the first support frame 52A, the second support frame 52B, the third support frame 52C, and the fourth support frame 52D. In this embodiment, the multiple support frames 52 consisted of four frames, but of course, they are not limited to this, and there may be three or five frames.

[0191] The first support frame 52A has a rectangular first hole 522A on the negative side of the Y-axis to which a fastener 50C described later is attached, and a circular second hole 521A on the positive side of the Y-axis of the first hole 522A. The first support frame 52A also has a rectangular first hole 523A on the positive side of the Y-axis to which a fastener 50C is attached, and a circular second hole 524A on the negative side of the Y-axis of the first hole 523A.

[0192] The fourth support frame 52D has a rectangular first hole 522D on the negative side of the Y-axis to which a fastener 50C is attached, and a circular second hole 521D on the positive side of the Y-axis of the first hole 522D. The fourth support frame 52D also has a rectangular first hole 523D on the positive side of the Y-axis to which a fastener 50C is attached, and a circular second hole 524D on the negative side of the Y-axis of the first hole 523D.

[0193] Furthermore, when the first support frame 52A and the first mounting support member 501D are fixed together by the fastener 50C described later, a portion of the fastener 50C is visible through the second hole 521A described above. Of course, this is not limited to the second hole 521A, but the same applies to the second holes 524A, 521D, and 524D.

[0194] The second support frame 52B includes a first frame 521B provided on the negative side of the first support frame 52A in the Z-axis direction and extending along the Y-axis direction, a second frame 522B provided on the negative side of the Y-axis of the first frame 521B and extending along the Z-axis direction, a third frame 523B provided on the positive side of the Z-axis of the second frame 522B, connected to the second column frame 51B and extending along the Y-axis direction, and a fourth frame 524B provided on the negative side of the Z-axis of the second frame 522B, connected to the second column frame 51B and extending along the Y-axis direction.

[0195] As shown in Figure 13, the second support frame 52B is used to mount the first electrical equipment 54A, which is attached to the first frame 521B, and the third electrical equipment 54C, which is attached to the third frame 523B and the fourth frame 524B. Mounting methods include, but are not limited to, a method using a DIN rail D, such as screw fastening.

[0196] In this embodiment, the DIN rail D is attached to the third support frame 52C, and the second electrical equipment 54B corresponding to the DIN rail D is attached to the DIN rail D. This reduces the need for screw fastening, thereby improving work efficiency.

[0197] As shown in Figure 13, the third support frame 52C is located on the negative side of the second support frame 52B in the Z-axis direction, extends along the Y-axis direction, and is located (connected) between the first column frame 51A and the second column frame 51B. The second electrical equipment 54B is mounted on the third support frame 52C.

[0198] The first electrical device 54A, the second electrical device 54B, and the third electrical device 54C are not particularly limited, but could be, for example, circuit breakers.

[0199] (Mounting support member) As shown in Figure 3, the mounting support member 50D is a frame having a first mounting support member 501D and a second mounting support member 502D.

[0200] As described above, the first mounting support member 501D is a frame connected to the mounting member connecting holes 115C, 115D, and 115E. Also as described above, the second mounting support member 502D is connected to the mounting member connecting holes 116C, 116D, and 116E. The mounting support member 50D is fixed to the second main frame 11C, 11D, and 11E, for example, by bolts and nuts.

[0201] The first mounting support member 501D has a corresponding hole 5012D that corresponds to the first hole 522A provided in the first support frame 52A. Although not shown, the first mounting support member 501D further has corresponding holes that correspond to the second hole 521A, the first hole 523A, and the second hole 524A.

[0202] Furthermore, the second mounting support member 502D has holes corresponding to the first hole 522D, the second hole 521D, the first hole 523D, and the second hole 524D provided in the fourth support frame 52D.

[0203] In this context, "corresponding" means that it is configured to penetrate the object when viewed from the X-axis direction.

[0204] (Intermediate connector) Figure 18 is an enlarged view of the relay connector 50B, Figure 19 shows a part of the first wiring group 90, and Figure 20 shows the wiring protection material 902. As shown in Figures 13, 18-19, the relay connector 50B is attached to the support member 50 (third support frame 52C). In this embodiment, the relay connector 50B is made of resin, for example.

[0205] The relay connector 50B is a connector for supplying power from an external power source via the first wiring group 90 (described later) to electrical equipment 54A, 54B, and 54C via the second wiring group 53 (described later). Here, the first wiring group 90 is inserted into the wiring hole 133 through the cylindrical portion 90A provided in it.

[0206] Furthermore, the relay connector 50B is configured to connect the first wiring group 90 and the second wiring group 53. Specifically, one end of the housing of the relay connector 50B has a first insertion opening (first connection part) 501B into which the first wiring group 90 (connector part 90B) is inserted, and the other end has a second insertion opening (second connection part) 502B into which the second wiring group 53 (multiple second terminals 532A) is inserted.

[0207] A relay terminal (not shown) is formed in the second insertion opening 502B, which is electrically connected to the connector 90 of the first wiring group 90. The relay terminal can be electrically connected to a plurality of second terminals 532A, which will be described later, via the second insertion opening 502B. The relay terminal can also be electrically connected to a plurality of first external terminals 902B of the connector 90B, which will be described later. This allows power supplied from an external power source to be supplied to a plurality of electrical devices 54A to 54C.

[0208] The first insertion port 501B and the second insertion port 502B of the relay connector 50B have a one-to-one relationship. That is, if the first wiring 901 is inserted into the third position from the top of the first insertion port 501B (see Figure 18), the power supplied from the first wiring 901 is supplied to the second wiring 53 which is inserted into, for example, the third position from the top of the second insertion port 502B.

[0209] (First wiring group) As shown in Figures 18-20, the first wiring group 90 includes a plurality of first wires 901, each having one end connected to an external power source and a plurality of first terminals 901A on the other end; a connector portion 90B that is electrically connected to the plurality of first terminals 901A and commonly supports the plurality of first terminals 901A; and a plurality of wiring protection materials 902 that bundle the plurality of first wires 901.

[0210] The connector section 90B includes a support base 901B that supports a plurality of first terminals 901A, and a plurality of external terminals 902B provided on the support base 901B and inserted into the first insertion opening 501B. The support base 901B is roughly rectangular and has insertion holes 9011B into which the plurality of first terminals 901A are inserted. The plurality of external terminals 901B are inserted into the first insertion opening 501B and are provided in the same number as the insertion holes 9011B. The number of wires in the plurality of wiring 901 corresponds to the number of electrical devices 54A, 54B, and 54C.

[0211] The wiring protection material 902 covers (bundles) multiple first wires 901, protecting the multiple wires 901 from external impacts, etc. The wiring protection material 902 is formed in a cylindrical shape and has an overlapping portion 9021 in the radial direction, and in this embodiment, it is a self-winding tube. A self-winding tube is a tube that has a self-winding characteristic in which it winds itself in the circumferential direction (contracts in the radial direction) when there is no external force, and has an overlapping portion in which both ends in the circumferential direction overlap by a certain angle.

[0212] Furthermore, the worker separates the overlapping portion of the wiring protection material 902 by hand or other means, and inserts multiple first wires 901 through the gap created. The wiring protection material 902 is, of course, not limited to, braided tubing or plastic tubing.

[0213] The first wiring group 90 has a fixing member 903 that holds the wiring protection material 902. The fixing member 903 is, for example, a cable tie, and holds the wiring protection material 902 to the support member 50A or the frame 10A. This prevents the first wiring group 90 from colliding with the housing device 1 due to vibration or the like. The fixing member 903 may also be used to tie the wiring protection material 902 together. This prevents the first wiring group 90 from being scattered haphazardly within the housing device 1.

[0214] The cylindrical portion 90 also has a packing (not shown) that fits into the wiring hole 133 and has an external wiring hole through which the first wiring group 90 is inserted. In this embodiment, the packing has one external wiring hole, and the external wiring hole is configured to allow the first wiring group 90, which has an outer diameter equal to or greater than the diameter of the external wiring hole, to pass through. This provides a waterproof structure to the hole through which the first wiring group 90 passes. In this embodiment, one external wiring hole is provided in one packing, but the structure is not limited to this, and two or more external wiring holes may be provided depending on the number of first wiring groups 90 to be inserted.

[0215] In this embodiment, power is supplied to electrical equipment 54A, 54B, and 54C from the first wiring group 90, which is made up of two wires, through the relay connector 50B and the second wiring group 53 (the first internal wiring 53A and the second internal wiring 53B). Of course, the number of wires in the first wiring group 90 is not limited to this, and there may be three or four wires.

[0216] (Second wiring group) As shown in Figures 13 and 18, the second wiring group 53 has a first internal wiring 53A and a second internal wiring 53B. In this embodiment, the first internal wiring 53A is connected to the first electrical equipment 54A and the third electrical equipment 54C, as shown in Figure 13. Also in this embodiment, the second internal wiring 53B is connected to the second electrical equipment 54B, as shown in Figure 13.

[0217] As shown in Figure 18, the first internal wiring 53A of the second wiring group 53 has multiple second wires 531A, each having multiple electrical devices 54A, 54C at one end and multiple second terminals 532A at the other end, and multiple wiring protection materials 530A that bundle the multiple second wires 531A. The multiple second terminals 532A are each inserted into the second insertion opening 502B.

[0218] The multiple wiring protection materials 530A have the same configuration as the multiple wiring protection materials 902, covering (bundling) the multiple second wirings 531A and protecting the multiple second wirings 531A from external impacts, etc. In this embodiment, the wiring protection material 531A is a self-wrapping tube.

[0219] Furthermore, the worker separates the self-wrapping tube of the wiring protection material 531A by hand or other means, and inserts multiple second wires 531A through the gap that is opened.

[0220] As shown in Figure 18, the second internal wiring 53B of the second wiring group 53 has the same configuration as the first internal wiring 53A, and comprises a plurality of second wires (not shown) having one end connected to a plurality of electrical devices 54B and a plurality of second terminals (not shown) on the other end, and a plurality of wiring protection materials 530B that bundle the plurality of second wires.

[0221] The second wiring group 53 has a fixing member 903 that holds the wiring protection materials 530A and 530B. The fixing member 903 is, for example, a cable tie, which holds the wiring protection materials 530A and 530B to the support member 50A or the like. This prevents the second wiring group 53 from colliding with the housing device 1 due to vibration or the like.

[0222] In this embodiment, power was supplied from the first internal wiring 53A to the first electrical equipment 54A and from the second internal wiring 53B to the second electrical equipment 54B. However, the system is not limited to this configuration, and it may be configured so that two second wiring groups 53 are connected to the first electrical equipment 54A and three second wiring groups 53 are connected to the second electrical equipment 54B. The arrangement of the relay connector 50B is not limited to the third support frame 52C, but may also be on the second support frame 52B.

[0223] [Fasteners] As shown in Figures 13-17, the fastener 50C is a panel fastener and comprises a mounting plate 501C, a bearing member 502C attached to the mounting plate 501C, and a pair of hooks 503C. The fastener 50C attached to the first hole 522A will be described below, but is not limited to this, and the same applies when attached to the first holes 524A, 522D, and 524D as to the first hole 522A.

[0224] The mounting plate 501C has a first mounting surface 5011C which is a plane larger than the first hole 522A. The first mounting surface 5011C is a plane parallel to the YZ side plane and parallel to the first support frame 52A. The mounting plate 501C also has a second mounting surface 5012C on the opposite side from the first mounting surface 5011C.

[0225] The bearing member 502C is attached to the first mounting surface 5011C and rotatably supports a pair of hooks 503C, which will be described later. The bearing member 502C is configured to be smaller than the first hole 522A and the first mounting hole 1121A when viewed from the X-axis direction.

[0226] The pair of hooks 503C are rotatably supported on the bearing member 502C described above, about the Z-axis. The pair of hooks 503C are configured to be larger than the first hole 522A and the first mounting hole 1121A when viewed from the X-axis direction. The pair of hooks 503C are also held by a coil in a position protruding from the bearing member 502C when viewed from the Z-axis direction.

[0227] When the fastener 50C is inserted through the first hole 522A and the first mounting hole 1121A, the pair of hooks 503C are pushed inward by the frames of the first hole 522A and the first mounting hole 1121A as it is inserted.

[0228] When the first mounting surface 5011C contacts the first support frame 52A, the pair of hooks 503C protrude outward due to the force of the spring. As a result, the pair of hooks 503C are locked to the first mounting support member 501D, thereby fixing the first support frame 52A to the main frame 11. Furthermore, when the first support frame 52A and the first mounting support member 501D are fixed together by the fastener 50C as described above, the pair of hooks 503C are made visible to the worker through the second hole 521A (see Figure 17).

[0229] The pair of hooks 503C may have a mark on a part visible from the second hole 521A. Here, the mark may be, for example, a red line or fluorescent paint. This makes it easier for the worker to see the pair of hooks 503C.

[0230] The fastener 50C has a release section 504C on the second mounting surface 5012C that houses a pair of hooks 503C within the bearing member 502C. The pair of hooks 503C are housed within the bearing member 502C by rotating the release section 504C around the X-axis direction. The release section 504C is rotated using a handle member or the like. This enables the attachment and detachment of the first mounting support member 501D and the mounting member 50.

[0231] [Third connecting member] As shown in Figures 1-4, the third connecting member 60 connects the main frame 11 and the subframe 12.

[0232] In this embodiment, the third connecting member 60 is a rivet, and more specifically, a flat-head rivet.

[0233] [Second connecting member] As shown in Figure 9, the second connecting member 70 connects the multiple first main frames 11A, 11B and the multiple second main frames 11C, 11D, 11E.

[0234] The connection points are a plurality of first bent connection holes 114A and second bent connection holes 114C, 113D, 114E, and a plurality of first bent connection holes 113B and second bent connection holes 114C, 113D, 114E. In this embodiment, the second connecting member 70 is a rivet, more specifically a round-head rivet.

[0235] [First connecting member] As shown in Figures 1-4, the first connecting member T connects the frame 10 to the first side portion 22 and the second side portion 23.

[0236] The first connecting member T is inserted through a plurality of first side connecting holes 22A to connect the subframes 12A, 12F, 12H and the second main frame 11C with the first side portion 22.

[0237] Furthermore, the first connecting member T is inserted through a plurality of second side connecting holes 23A to connect the subframes 12E, 12G, 12J and the second main frame 11E with the second side portion 23.

[0238] In this embodiment, the first connecting member T is a rivet, more specifically, a waterproof rivet. This improves the airtightness of the housing device 1.

[0239] (Manufacturing method for containment device) Next, a description will be given of the manufacturing method for the housing device 1 of this embodiment, which is configured as described above.

[0240] The manufacturing method for the storage device 1 in this embodiment includes the steps of assembling a frame structure 10, attaching mounting members 50 to the frame structure 10, and assembling a plate portion 20 and a door portion 30 to the frame structure 10 to which the mounting members 50 have been attached.

[0241] The process of assembling the frame structure 10 will now be explained (see Figures 5-9). First, the main frame body 11 is assembled (see Figures 8 and 9). As described above, the main frame body 11 is assembled by connecting and fixing the first main frames 11A and 11B and the second main frames 11C, 11D and 11E with the second connecting member 70. In this way, the main frame 11 is assembled as shown in Figure 8.

[0242] In this case, the method of connecting the first main frames 11A, 11B and the second main frames 11C, 11D, 11E may involve not only the second connecting member 70, but also fillet welding at the points connected by the second connecting member 70.

[0243] Next, the subframe 12 is connected to the main frame 11 (see Figures 6 and 7). The connection (assembly) of the main frame 11 and the subframe 12 is achieved by connecting and fixing them together using the third connecting member 60, as described above.

[0244] At this time, fillet welding may be performed on the contact points between the main frame 11 and the subframe 12.

[0245] Next, the bottom portion 40, front portion 13, and rear portion 14 are connected to the main frame body 11 and subframe 12 (frame body 10A) (see Figure 5). The main frame body 11 and subframe 12 are fixed (connected), welded, or bonded to the bottom portion 40 by bolts and nuts, or by welding or adhesive. The subframe 12 (for example, the first fitting portions 125B, 126B) is welded to the front portion 13 and rear portion 14. The bottom portion 40 and the front portion 13 and rear portion 14 are fixed (connected), welded, or bonded by bolts and nuts, or by welding or adhesive. This completes the assembly of the frame structure 10.

[0246] Next, the process of attaching the mounting member 50 to the frame structure 10 will be described (see Figures 3, 5, 13-17). First, the mounting support member 50D is attached to the inside of the frame structure 10 in the state shown in Figure 5 (see Figure 3, however, in this embodiment, the side portions 22 and 23 are not attached at this stage).

[0247] Next, the mounting member 50 is inserted into the frame structure 10 in the state shown in Figure 5. There are no particular limitations on which direction (X-axis direction, Y-axis direction, or Z-axis direction) the mounting member 50 is inserted into the frame structure 10, but in this embodiment, the mounting member 50 is inserted from the X-axis direction (front part 13 or rear part 14).

[0248] Next, the mounting member 50, which has electrical equipment 54, internal wiring 53, and relay connector 50B, is attached to the frame structure 10 via the mounting support member 50D (see Figure 3, 14-18). The mounting support member 50D and the mounting member 50 are fixed together, for example, in four places by fasteners 50C, as described above. In this way, the mounting member 50 is attached to the frame structure 10 via the mounting support member 50D that is attached to it.

[0249] Next, as shown in Figure 17, the user checks whether a part of the fastener 50C (a pair of hooks 503C) is visible from the second hole 521A. If a part of the fastener 50C (a pair of hooks 503C) is visible from the second hole 521A, as shown in Figure 17, it is determined that the mounting member 50 has been attached to the mounting support member 50D (frame structure 10).

[0250] Next, the cylindrical parts 90A are attached to multiple wiring holes 133, and the external wiring 90 is connected to the relay connector 50B via the cylindrical parts 90A.

[0251] Next, the process of assembling the plate portion 20 and the door portion 30 to the frame structure 10 to which the mounting member 50 is attached will be described (see Figures 1-4). First, the first side portion 22 and the second side portion 23 are connected to the frame structure 10 by the first connecting member T as described above.

[0252] Next, the top surface 21 is connected to the frame structure 10 to which the first side surface 22 and the second side surface 23 are attached, using bolts B and nuts N as described above.

[0253] Next, the door sections 30 are attached to the front section 13 and the rear section 14. This completes the assembly of the plate section 20 and the door section 30 onto the frame structure 10, and the storage device 1 is assembled (see Figure 1).

[0254] As described above, the mounting member 50 can be attached to the frame structure 10 before the plate portion 20 is connected to the frame structure 10. Therefore, when attaching the mounting member 50 to the frame structure 10, the worker (user) can reach in from the Y-axis direction to support the mounting member 50 or align it for connection. As a result, even if the mounting member 50 is heavy, it is possible to support it with the help of multiple people while installing it, thus improving the efficiency of the installation work for the mounting member 50.

[0255] Since the main frame 11 and the subframe 12 are connected by a third connecting member 60, the welding process can be reduced. This makes it easy to fix the main frame 11 and the subframe 12 in place.

[0256] Since the first main frames 11A, 11B and the second main frames 11C, 11D, 11E are connected by the second connecting member 70, the welding process can be reduced. This makes it easy to fix the first main frames 11A, 11B and the second main frames 11C, 11D, 11E in place.

[0257] Furthermore, the frame 10 and the plate section 20 are fixed together by rivets. This reduces welding work, making it easy to fix the frame 10 and the plate section 20 together. Similarly, the first main frames 11A, 11B and the second main frames 11C, 11D, 11E are also fixed together by rivets. This reduces fastening work using bolts and nuts or welding, making it easy to fix the frame 10 and the plate section 20 together.

[0258] When attaching the mounting member 50 to the mounting support member 50D (framework 10), it is possible to determine whether the mounting member 50 is securely attached to the mounting support member 50D (framework 10) by whether the pair of hooks 503C are visible through the second hole 521A, making it easy for the worker to confirm. Furthermore, since the mounting member 50 is attached to the mounting support member 50D (framework 10) by fasteners 50C (panel fasteners), the mounting member 50 can be easily attached to the mounting support member 50D (framework 10) without using bolts and nuts.

[0259] Since the frame 10 and the plate section 20 are connected by bolts B and the first connecting member T, the welding process can be reduced. This makes it easy to fix the frame 10 and the plate section 20 together. Alternatively, a sealant may be applied between the frame 10 and the plate section 20, for example, using a caulking gun. In this case, the sealant is applied to the areas where the frame 10 and the plate section 20 come into contact. This improves airtightness. Of course, it is not limited to a caulking gun; a tape-like sealant can also be used.

[0260] Furthermore, since the mounting member 50, which has electrical equipment 54A, 54B, and 54C on which the second wiring group 53 is arranged, is attached to the frame 10, there is no need to perform the work of installing the electrical equipment 54A, 54B, and 54C inside the frame 10. In other words, since the electrical equipment 54A, 54B, and 54C and the second wiring group 53 can be attached to the support member 50A in advance and then attached to the frame 10, workers can efficiently perform the installation work of the electrical equipment 54A, 54B, and 54C and the wiring work of the second wiring group 53.

[0261] Furthermore, the mounting member 50 has a relay connector 50B for supplying power output from an external power source to each of the multiple electrical devices 54A, 54B, and 54C. This eliminates the need to wire the first wiring group 90 to each of the electrical devices 54A, 54B, and 54C individually. In other words, it is only necessary to connect the first wiring group 90 to the relay connector 50B (the second wiring group 53 is already connected from the relay connector 50B to each of the electrical devices 54A, 54B, and 54C), thus improving the efficiency of the wiring work. Moreover, in this embodiment, since the housing supporting the mounting member 50 is a frame 10, when connecting the first wiring group 90 to the relay connector 50B, the worker can reach in from various directions to perform the work, thus enabling efficient wiring work.

[0262] In addition, when wiring was passed through each individual tube, it was labor-intensive. However, with the wiring protection materials 902, 530A, and 530B of the present embodiment, it can be easily attached. Furthermore, with the wiring protection materials 902, 530A, and 530B of the present embodiment, it can be attached even later to protect a plurality of first wirings and second wirings.

[0263] Also, as described above, since the attachment member 50 is composed of the column frame 51 and the support frame 52, the degree of freedom in arranging the electrical equipment 54 can be increased. For example, a plate parallel to the XZ plane can be attached between the third frame 523B and the fourth frame 524B, and a plurality of second electrical equipment 54C can be arranged side by side from both sides of the plate. That is, since the attachment member 50 has a three-dimensional structure, three-dimensional electrical equipment 54 can be arranged, and more electrical equipment 54 can be accommodated.

[0264] Also, as described above, since the attachment member 50 is composed of the column frame 51 and the support frame 52, a plurality of electrical equipment 54 with different sizes can be easily arranged (see FIG. 13).

[0265] Since the attachment member 50 is formed of an aluminum frame, weight reduction and cost reduction can be achieved compared to the case of processing and painting using sheet metal.

[0266] In addition, since the elastic member 80 is provided on the door portion 30 side and is a single piece, the attachment work of the elastic member 80 can be facilitated. Also, since the bulging portion 82 of the elastic member 80 is brought into contact with the flange portion 131B, the door portion 30 can be easily closed (for example, compared to the case where a gasket is provided on the front portion 13 side and the door folding portion 32A is pressed against the gasket).

[0267] Also, since the housing device 1 can maintain the strength of the box with the above-described framework structure 10, the thickness of the plate portion 20 can be reduced, so that the manufacturing cost can be suppressed.

[0268] Furthermore, as described above, since the main frame 11 and the multiple subframes 12A to 12J are fitted together, when assembled as a frame structure 10, wobbling around the Z axis can be suppressed (deformation into a parallelogram-like shape is suppressed).

[0269] Furthermore, as described above, since the front section 13 and the rear section 14 are fitted together with the multiple subframes 12A to 12J, when assembled as a frame structure 10, rattling around the Z axis can be further suppressed (it suppresses deformation into a parallelogram-like shape).

[0270] In this embodiment, the first wiring group 90 has a support base 901B, but of course, it is not limited to this, and may be configured such that, for example, a plurality of first terminals 901A are inserted into the first insertion opening 501B, as in the second wiring group 53. Also, in this embodiment, the second wiring group 53 does not have a connector part 90, but of course, it is not limited to this, and may be configured such that it is inserted into the second insertion opening 502B via a connector part, as in the first wiring group 90.

[0271] <Second Embodiment> Next, a second embodiment of the present invention will be described. Figure 21 is a perspective view of the storage device 1' in the second embodiment, in which the door portion 30 and the top portion 21 have been removed and the multiple side portions 22 and 23 have been removed. Figure 22 is a perspective view of the main frame 11' in the second embodiment. Figure 23 is a diagram of the first curtain rail portion 51R in the second embodiment, where (A) is a cross-sectional view of the first curtain rail portion 51R and (B) is a perspective view of the first curtain rail portion 51R. Figure 24 is a perspective view of the support member 50A' and the first curtain rail portion 51R in the second embodiment. Hereinafter, configurations different from the first embodiment will be mainly described, and the same reference numerals will be used for configurations similar to the first embodiment, and their descriptions will be omitted or simplified.

[0272] The housing device 1' of this embodiment differs from the first embodiment in that the curtain rail portion 50R is attached to the main frame body 11'. The mounting member 50 includes a curtain rail portion 50R that extends along the Y-axis direction and is provided parallel to each other and fixed to the main frame body 11' by a fastener B0, a first bolt B1 provided on the curtain rail portion 50R and movable in the Y-axis direction, and a first nut N1 that fits with the first bolt B1.

[0273] The main frame body 11' also has rail connecting holes 115C', 116C', 115D', 116D', 115E', and 116E' through which the fastener B0 passes (see Figure 22).

[0274] In this embodiment, the curtain rail section 50R is provided between the second main frames 11C' and 11D' of the main frame body 11' with a predetermined gap in between. In this embodiment, the curtain rail section 50R has two sections: a first curtain rail section 51R and a second curtain rail section 52R. The first curtain rail section 51R extends along the Y-axis direction, with one end in the Y-axis direction connected to the second main frame 11D' and the other end in the Y-axis direction connected to the second main frame 11C'. The second curtain rail section 52R extends along the Y-axis direction, with one end in the Y-axis direction connected to the second main frame 11D' and the other end in the Y-axis direction connected to the second main frame 11C', and faces the first curtain rail section 51R in the Z-axis direction. Here, the predetermined gap is approximately the same as the length of the support member 50A' in the Z-axis direction, for example, a few centimeters, a dozen centimeters, or several tens of centimeters.

[0275] Here, the method of fixing the curtain rail section 50R to the main frame 11 will be explained using the first curtain rail section 51R and the second main frame 11D'.

[0276] As shown in Figures 21 to 23(A), the first curtain rail section 51R is fixed to the second main frame 11D' via a fastener B0 at one end (negative Y-axis side). In this embodiment, the fastener 50C' is a bolt and nut (not shown), but is not limited to this and may be a rivet.

[0277] The second main frame 11D' has a rail connection hole 115D through which the fastener B0 passes. Similarly, as shown in Figures 21 to 23(A), the other end (positive Y-axis side) of the first curtain rail section 51R is also fixed to the second main frame 11C' via the fastener B0. The second main frame 11C' also has a rail connection hole 115C' through which the fastener B0 passes. The rail connection holes 115C' and 115D' are aligned in a straight line in the Y-axis direction.

[0278] In other words, the fastener B0 penetrates the first curtain rail section 51R and the rail connecting holes 115C' and 115D', thereby fixing the first curtain rail section 51R to the second main frames 11C' and 11D'.

[0279] The second curtain rail section 52R is fixed to the main frame 11 in the same way as the first curtain rail section 51R.

[0280] Next, the method for fixing the curtain rail section 50R to the support member 50A' will be described. The first curtain rail section 51R has a first groove 501R into which the first bolt B1 can move toward the positive direction of the X-axis (front section 13 or support member 50A'). The second curtain rail section 52R has a second groove 502R into which the first bolt B2 can move toward the positive direction of the X-axis (front section 13 or support member 50A').

[0281] The first groove 501R and the second groove 502R extend along the Y-axis direction and are positioned to overlap with the fastening holes 501A' and 502A', which will be described later, when viewed from the X-axis direction. The head of the first bolt B1 is provided in the first groove 501R so as to be slidable in the Y-axis direction. The head of the second bolt B2 is provided in the second groove 502R so as to be slidable in the Y-axis direction.

[0282] Furthermore, the support member 50A' has a surface parallel to the Y-axis direction and is a rectangular support plate (plate-like) that supports the electrical equipment 54, and has a plurality of fastening holes 501A' at the four corners of the rectangle. As shown in Figure 21, the plurality of fastening holes 501A' are provided in positions that overlap with the first groove 501R and the second groove 502R described above when viewed from the X-axis direction.

[0283] The first bolts B1 and B2 can be slid through the multiple fastening holes 501A', and the support member 50A' can be fixed using the first bolts B1 and B2 and the first nuts N1 and N2.

[0284] As described above, since the first bolts B1 and B2 are configured to be movable (slidable), there is no need to increase the precision of the spacing between the multiple fastening holes 501A' compared to when the bolt positions are fixed. Therefore, the work efficiency when fixing the support member 50A' (mounting member) to the main frame 11' can be improved.

[0285] Furthermore, in this embodiment, the first bolts B1 and B2 were fixed by passing through multiple fastening holes 501A', but this is not limited to this. For example, the multiple fastening holes 501A' may be notches cut in the Y-axis direction. This can further improve the work efficiency when fastening.

[0286] Furthermore, although this embodiment was described using a support plate, the explanation is of course not limited to this, and a support member 50A (see Figure 14) may also be used.

[0287] Furthermore, in the present embodiment, the curtain rail portion 50R is provided between the second main frames 11C' and 11D', but the present invention is not limited to this, and the curtain rail portion 50R may be provided between the second main frames 11D' and 11E'.

[0288] For example, the method of fixing the plate-like support member 50A' to the framework 10 may be the method using the panel fastener 50C described above in addition to the fixing by the curtain rail portion 50R. That is, the support member 50A' may be formed with a first hole portion to which the panel fastener 50C is attached and a second hole portion for confirming that the panel fastener 50C is sufficiently attached, similar to the support member 50A.

[0289] As described above, the embodiments of the present invention have been described. However, the present invention is not limited only to the above-described embodiments, and various modifications can be made, and it is of course possible to combine the configurations of each embodiment and modification example. For example, in the present embodiment, the housing device 1 installed under the floor of the railway vehicle has been described, but it may be provided, for example, on the railway vehicle floor device, indoor and outdoor switchboards, distribution boxes, equipment rooms, etc.
