Description

[Technical field]

[0001] The present invention relates to a mounting structure for mounting an electrical device, such as an audio device, on a storage rack, such as a rack case, and to the electrical device. [Background technology]

[0002] Audio equipment and electronic information equipment (hereinafter referred to as "electrical devices") may be used individually or in combination with multiple units. For example, audio equipment may be connected to devices such as amplifiers, tuners, equalizers, and selectors, and each device may be operated according to the situation during use. Electronic information equipment may also be connected to multiple servers and storage devices, allowing them to back up each other. When multiple units are used in combination in this way, it is customary to mount and store each piece of electrical equipment in a rack case, server rack, etc. (hereinafter referred to as a "storage rack") for ease of operation and storage, as well as to protect the electrical equipment.

[0003] The storage rack has storage compartments with a predetermined width for storing electrical devices, and the electrical devices can be mounted in a number of levels. The housing of the electrical device is designed to fit the width of the storage section. When multiple electrical devices are to be installed, the electrical devices are installed in the storage section with a small gap between each other in the height direction. However, for electrical equipment with compact electrical components housed inside, it would be redundant and uneconomical to match the width of the housing to the width of the storage rack, so the width is sometimes designed to be about half the width of the storage rack. In this case, two electrical equipment can be mounted side-by-side on one level.

[0004] For example, Patent Document 1 discloses an example of a connecting structure for electronic devices that enables two electronic devices to be attached side-by-side on one level by inserting a connecting device of a predetermined shape into the electronic device (corresponding to the electrical device). In more detail, the electronic device connecting structure 900 of Patent Document 1, as shown in FIG. 11, arranges electronic devices 91 / 91, each having engagement grooves 93 / 93' on the left and right sides, side by side, and inserts a connecting device 92 having a shape that corresponds to the opposing engagement grooves 93 / 93', thereby enabling two electronic devices 91 / 91 to be attached in one row. Further, the electronic devices 91·91 are attached to each other by using other connecting devices 92·92 in the engaging grooves 93'·93 on the outside thereof and placing them on rails 94 of a rack (corresponding to a storage rack).

[0005] [Patent Document 1] JP 2001-352180 A Summary of the Invention [Problem to be solved by the invention]

[0006] In the example disclosed in Patent Document 1, the width of the electronic device is half the width of the storage section of the rack. Therefore, when mounting the electronic device on the rack by itself, the electronic device is largely separated from one of the rails, and it is necessary to mount the electronic device on the rail using a mounting tool for mounting a single device, which has a long and large shape different from the above-mentioned connecting tool.

[0007] However, some buyers of electronic devices use the electronic device alone, while others use two devices connected together. Therefore, the connecting device and the mounting device may or may not be necessary depending on the demand. Therefore, the connecting device and the mounting device must be sold as optional parts separate from the electronic device, which is uneconomical in terms of manufacturing and management, and also causes problems for buyers, who must order them separately from the electronic device, which is troublesome. On the other hand, if both the connecting device and the connecting device are attached to the electronic device, unnecessary parts must be discarded, which is not only uneconomical for the purchaser but also leads to an increase in waste, which is unsuitable from the environmental point of view.

[0008] The present invention has been made in consideration of the above-mentioned problems, and has as its object to provide an electrical device mounting structure and electrical device therefor which is economical and has no losses in manufacturing and management, and which is also environmentally friendly, whether the electrical device is mounted on a storage rack as a single unit or when two units are firmly connected together. [Means for solving the problem]

[0009] The means adopted by the present inventors to solve the above problems will be described below. The mounting structure for electrical equipment of the present invention is configured so that it can be mounted to a storage rack either in a state where a single electrical equipment is fixed thereto, or in a state where two electrical equipment are connected together. Its basic configuration is such that the electrical device can be fixed to the storage rack in a single state using a shared fixing means and a rack fixing means, while two such electrical devices can be connected together using the shared fixing means. The two connected electrical devices are configured to be mountable to the storage rack by using a plurality of the rack fixing means.

[0010] In the above basic configuration, when a single electrical device is fixed to the storage rack, the common fixing means and the rack fixing means are used. When two electrical devices are connected and fixed to the storage rack, the common fixing means is used to connect the electrical devices, and the rack fixing means is used to fix the connected electrical devices to the storage rack. In other words, whether the electrical device is mounted in a single state or in a state where two electrical devices are connected to each other, the common fixing means and the rack fixing means are always used.

[0011] Therefore, for example, when an electrical device is sold, if one common fixing means and one rack fixing means are attached to each unit of electrical device, a person who wants to use it as a standalone device can purchase one unit, and a person who wants to use two units in a linked configuration can purchase two units, allowing either person to use the attached parts without excess or deficiency. It is not essential that one common fixing means and one rack fixing means are used, but two common fixing means and two rack fixing means may be used.

[0012] In addition to the above means, the means adopted by the present invention to solve the above-mentioned problems include making the width of the housing part of the electrical device less than half the width between the rack rails provided at both ends of the storage section in the storage rack, and making it possible to attach the electrical device to the rack rails while it is stored in the storage section with the electrical device lined up in the width direction. In this configuration, when the electrical equipment is attached to the rack rail in a standalone state, the opening of the space adjacent to the electrical equipment stored in the storage section is covered by the shared fixing means.

[0013] In the above-mentioned means, the electrical device is configured to be attached to rack rails provided at both ends of the storage section. When the electrical device is attached to the rack rails, if the width of the housing of the electrical device is less than half the width between the rack rails, when the electrical device is attached to the rack rails as a standalone unit, a space is created in the storage section other than the electrical device, and an opening is created in front of the space. In a storage rack that is attached to the rack rails, each level of the storage section generally does not have a bottom plate, so the space is visible from the front of the storage rack through the opening, and the top and bottom surfaces, wiring, etc. of the electrical device on the other levels are visible.

[0014] Therefore, by configuring the shared fixing means that fixes the electrical equipment to the rack rail to cover the opening of the space adjacent to the electrical equipment, it is possible to prevent the top, bottom, wiring, etc. of electrical equipment on other levels from being visible through the opening adjacent to the electrical equipment when the storage rack is viewed from the front.

[0015] As another means adopted by the present invention to solve the above-mentioned problems, in the above configuration in which the shared fixing means is attached to the rack rail, it is also possible to configure the shared fixing means to include a shared fixing portion and an apparatus-side fixing portion. In the case of this configuration, when the electric device is fixed in a stand-alone state, the shared fixing part is fixed to the storage rack, and the device-side fixing part is fixed to one of the sides of the electric device. The side to which the shared fixing part is not fixed is fixed to the electric device by using a rack fixing means. In addition, when two of the electric devices are fixed in a connected state, the device-side fixing part is fixed to a surface of one of the electric devices other than the side facing the other electric device, and the shared fixing part is fixed to a surface other than the surface to which the device-side fixing part is fixed. Each electric device and the storage rack are fixed using a rack fixing means. However, in any of the above cases, the electrical device is not limited to being a rectangular parallelepiped, and may be in another three-dimensional shape.

[0016] With the above-mentioned configuration, the device-side fixing portion of the shared fixing means is fixed to a predetermined surface of one of the electric devices, and the shared fixing portion connected thereto is fixed to a common surface of each of the electric devices. As a result, a common structure, that is, the common fixing portion of the common fixing means, is fixed to a predetermined common surface of each of the electric devices, so that each of the electric devices can be securely connected.

[0017] In the above configuration for fixing two electric devices in a connected state, two of the shared fixing means may be used, and the device-side fixing portion of one shared fixing means may be fixed to the outer side surface of one electric device, and the shared fixing portion of one shared fixing means may be fixed to the bottom surface of each electric device. In this case, the device-side fixing portion of the other shared fixing means is fixed to the outer side surface of the other electric device, and the shared fixing portion of the other shared fixing means is fixed to the bottom surface of each electric device.

[0018] With the above-mentioned configuration, both side surfaces of the two electric devices arranged side by side and the bottom surface of each electric device can be fixed by the two common fixing means. This allows the two electrical devices to be securely connected without interfering with the display unit and operation unit on the front side or the connection unit on the back side. Furthermore, by fixing the shared fixing portion of each shared fixing means to the bottom surface of each electrical device, the shared fixing means becomes difficult to see when visually inspecting the electrical devices stored in the storage rack, allowing the electrical devices to be stored neatly.

[0019] On the other hand, in order to solve the above problems, the electric device of the present invention can also be configured as follows. The electrical device of the present invention is configured so that it can be mounted on the storage rack either as a single unit or in a state in which two units are connected together. Its basic configuration is such that it can be fixed to the storage rack in a single state using a shared fixing means and a rack fixing means, while two electrical devices can be connected together using the shared fixing means, and the two connected electrical devices can be attached to the storage rack using multiple rack fixing means.

[0020] The common fixing means and the rack fixing means are means for fixing the electrical device to the storage rack in a standalone state. In the above basic configuration, the common fixing means and the rack fixing means can be used, so that the electrical device can be attached to the storage rack in a standalone state. The common fixing means can also be used to fix two electric devices in a connected state to the storage rack. In the electric device having the above configuration, the common fixing means is configured to enable connection of the electric devices, so that two electric devices can be connected and fixed to the storage rack. In other words, by using the common fixing means and the rack fixing means, it is possible to mount the electrical device in a single state, and it is also possible to mount two units in a linked state.

[0021] In the above configuration, it is also possible to configure the device to have at least left and right side surfaces and a bottom surface, to which the device side fixing portion of the shared fixing means can be fixed, and to which the shared fixing portion of the shared fixing means, which can also be fixed to rack rails provided at both ends of the storage section in the storage rack, can be fixed, to which the bottom surface can be fixed. In this configuration, the left and right side surfaces are each provided with a screw hole capable of fixing the device-side fixing part, and the bottom surface is provided with a screw hole capable of fixing the common fixing part regardless of which side the device-side fixing part is fixed to.

[0022] With the above configuration, when two electrical devices are connected and attached to a storage rack, the shared fixing means do not interfere with each other regardless of whether the electrical devices are placed on the left or right side, and the electrical devices can be connected and fixed using the two shared fixing means and fixed to the rack rail of the storage rack using the rack fixing means. Effect of the Invention

[0023] As described above, the mounting structure for electrical equipment of the present invention always uses the common fixing means and the rack fixing means whether the electrical equipment is mounted in a single state or in a connected state of two electrical equipment. In other words, when the same number of common fixing means and rack fixing means are attached to one electrical equipment to form one set, when the electrical equipment is mounted in a single state, all the contents of one set are used, and when two electrical equipment are mounted in a connected state, all the contents of two sets are used. Therefore, no unnecessary parts are produced, and the manufactured parts are always used. From a sales point of view, by providing both the common fixing means and the rack fixing means in advance, the purchaser can select either mounting state.

[0024] Therefore, the present invention has the advantage that there is no loss in manufacturing or management and is economical, whether the electrical device is mounted on the storage rack in a single state or in a state where two devices are firmly connected together. Moreover, regardless of which of the above mounting states is selected, there is an advantage that no unnecessary parts that need to be discarded are generated, and the impact on the environment is reduced.

[Figure 11]FIG. 1 is an explanatory diagram illustrating a conventional example. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. It should be noted that each drawing is drawn diagrammatically for the purpose of explanation, and some dimensions and shapes are shown exaggerated or simplified.

[0027] The mounting structure 100 for electrical equipment of the present invention is configured so that it can be mounted to a storage rack C in either a single state where the electrical equipment 1 is fixed thereto, or in a state where two electrical equipment units 1 and 1' are connected together. The storage rack C shown in Fig. 1 is, for example, a rack case for storing audio equipment, and the electrical device 1 shown in the mounting structure of Fig. 2 is, for example, a wireless receiver. Note that the storage rack C is not limited to a rack case, but may be a server rack or a storage box, and the electrical device 1 is not limited to audio equipment such as a wireless receiver, but may be a network device or a control device, etc.

[0028] The storage rack C shown in Figure 1 has a large space in the center, which is a storage section S. Front rack rails F and F' are provided at both front ends of the storage section S, and rear rack rails R and R' are provided at both rear ends. The front rack rails F.F' and the rear rack rails R.R' have a plurality of screw holes H.H... formed at predetermined intervals. The spacing between the screw holes H.H... on the left and right rails and the height spacing between the screw holes H.H... on each rail can be dimensions that comply with, for example, EIA standards.

[0029] The storage rack C shown in Fig. 1 is a 12U size (1U is 1.75 inches) storage rack C that conforms to the EIA standard and can store twelve 1U-high devices, one on each shelf. The storage section S can store devices with a width of 19 inches, and the electrical equipment 1 is 9.5 inches wide, half of 19 inches.

[0030] Fig. 2 shows the case where the electric device 1 is fixed in a standalone state. As described above, the width of the housing part of the electric device 1 is about half (9.5 inches) of the width (19 inches) of the front rack rails F·F', and two units of the electric device 1·1 can be stored side-by-side in the storage section S. In Fig. 2(a), the electric device 1 is attached as a single unit close to the front rack rail F on the left side as viewed from the front of the storage section S. Note that, as shown in Fig. 2(b), the electric device 1 may be attached close to the front rack rail F' on the right side as viewed from the front.

[0031] The electric device 1 and the front rack rail F' on the right side as viewed from the front are fixed with screws via common fixing means 2. Moreover, the electric device 1 and the front rack rail F on the left side as viewed from the front are fixed with screws via rack fixing means 3.

[0032] In Fig. 2(a), the right side of the electrical device 1 in the storage section S is an empty space, but the shared fastening means 2 is arranged to cover the opening on the front side and is screwed to the front rack rail F' on the right side. Therefore, the shared fastening means 2 conceals the space to the right of the electrical device 1, and it is possible to prevent other electrical devices and wiring attached to the upper and lower levels from being visible through the opening when viewed from the front. This allows the overall appearance of the storage case C to be improved. The same applies to the case of Fig. 2(b).

[0033] Fig. 3(a) shows the case where two electric devices 1 and 1' are connected and fixed without any gaps. The electric device 1 on the left side as viewed from the front is fixed to the left front rack rail F via rack fixing means 3 with screws. Also, the electric device 1' on the right side as viewed from the front is fixed to the right front rack rail F' via rack fixing means 3 with screws. In other words, two rack fixing means 3·3 are used.

[0034] As shown in Fig. 3(b), which is a bottom view, each of the electrical devices 1·1' is connected by being screwed to the common fixing means 2. The common fixing means 2·2 are installed parallel to each other with no gaps between them, with their positions shifted. In other words, two common fixing means 2·2 are used. The number of shared fixing means 2 used may be two or more.

[0035] Next, the common fixing means 2 and the rack fixing means 3 will be described with reference to FIG. The common fixing means 2 can be, for example, a metal fitting formed by bending a plate material such as a cold-rolled steel plate into an L-shape as shown in Fig. 4(a), but is not limited to this form and can be in other forms as long as it can be fixed to the electric device 1 and the storage rack C. The common fixing means 2 has a long piece that is the common fixing part 21 and a short piece that is the device-side fixing part 22 that is perpendicular to the common fixing part 21. The common fixing means 2 may have other surfaces in addition to the common fixing part 21 and the device-side fixing part 22. The material may be metal such as cold-rolled steel plate, or other materials such as resin.

[0036] The common fixing means 2 in Fig. 4(a) is made by punching a cold-rolled steel plate, removing burrs, bending, and then painting the surface and end faces. By painting, oxidation of the surface and end faces can be prevented, and the appearance can be made to match the appearance of the electric device 1.

[0037] The shared fixing portion 21 of the shared fixing means 2 is provided with a plurality of circular holes 23... and a plurality of oval holes 24.... In the embodiment shown in Fig. 4(a), there are four circular holes 23 and two oval holes. The circular holes 23... are holes for screwing to the electric device 1 when attaching two electric devices 1 (described later) in a connected state, and the size, number and positions are appropriately set according to the electric device 1.

[0038] The oblong holes 24 are holes for screwing into the screw holes HH... of the front rack rails F.F' when mounting the electric device 1 alone. The size, number and position of the oblong holes 24 are appropriately set in accordance with the EIA standard to match the screw holes HH... of the front rack rails F.F'. The common fixing part 21 and the device-side fixing part 22 may have holes other than those described above. For example, they may have screw holes for mounting to a storage rack other than that of the EIA standard. The fixing means may be other fastening means such as rivets other than screws.

[0039] Moreover, the device-side fixing portion 22 of the shared fixing means 2 is also provided with a plurality of round holes 23.... In the embodiment shown in Fig. 3(a), two round holes 23 are provided. The round holes 23... are holes for screwing to the electric device 1, and the size, number and positions are appropriately set according to the electric device 1 side.

[0040] On the other hand, the rack fixing means 3 can be, for example, a metal fitting formed by bending a plate material such as a cold-rolled steel plate into an L-shape as shown in Fig. 4(b), but is not limited to this form and can be of other forms as long as it can be fixed to the electric device 1 and the storage rack C. The rack fixing means 3 has a rack-side fixing part 31 and an apparatus-side fixing part 32 that is perpendicular to the rack-side fixing part 31. The apparatus-side fixing part 32 has the same length as the apparatus-side fixing part 22 of the shared fixing means 2, but the rack-side fixing part 31 is different from the shared fixing part 21 of the shared fixing means 2 and has a length that is only slightly shorter than the apparatus-side fixing part 32. The presence or absence of other surfaces, the materials, manufacturing methods, and surface treatments are the same as those of the common fixing means 2.

[0041] The rack side fixing portion 31 of the rack fixing means 3 is also provided with a plurality of round holes 33·33... and a plurality of oval holes 34·34.... The rack fixing means 3 in Fig. 4(b) has two round holes 33 and two oval holes 34. The sizes, number and positions of the round holes 33·33... and the oval holes 34·34... are similar to those of the common fixing means 2, but the rack fixing means 3 differs from the common fixing means 2 in that it is not used to connect two electrical devices 1.

[0042] Further, the device-side fixing portion 32 of the rack fixing means 3 is also provided with a plurality of round holes 33. In the embodiment shown in Fig. 4(b), two round holes 33 are provided. The round holes 33 are holes for screwing to the electric device 1, and the size, number and positions are appropriately set according to the electric device 1 side.

[0043] Next, the electric device 1 of the present invention will be described with reference to FIGS. The housing of the electric device 1 is a flat rectangular parallelepiped, and electrical components such as a printed wiring board and a transformer are attached to a chassis member, which is then covered with a cover member (not shown). The chassis member is formed by punching and then bending a metal plate such as an electro-galvanized steel plate. The cover member is also formed from the same material and by the same manufacturing method, but since it is an exterior part, it is painted after bending.

[0044] The housing of the electrical device 1 is configured to have a width of 9.5 inches (half of 19 inches) or less and a height of 1U (1.75 inches) or less, and is sized and shaped so that two units can be stored side-by-side in the space of one shelf of the storage section S of the storage rack C. In addition, the height may be doubled to 2U, in which case six units can be stored in the storage section S. Similarly, the height may be tripled to 3U.

[0045] The electrical device 1 shown in Fig. 5 has six sides, a right side 11, a left side 12, a bottom side 13, a top side 14, a front side 15, and a rear side 16, when viewed from the front. As shown in Fig. 5(a), the front side 15 has an operation unit 151 such as a switch or an encoder, and a display unit 152 such as a liquid crystal or an indicator. Also, as shown in Fig. 5(b), the rear side 16 has a connection unit 161 such as an inlet, an outlet, a connector, etc.

[0046] As shown in Fig. 6(a), a number of screw holes are provided on the right side surface 11 of the electric device 1. Among these screw holes, front screw holes 111-111 are provided at positions closer to the front surface 15 for screwing the electric device 1 to the common fixing means 2 or the rack fixing means 3. In addition, at a position closer to the back surface 16 than the front screw holes 111·111, a rear screw hole 112 is provided for screwing to the device side fixing portion 22 of the common fixing means 2 when installing two electrical devices 1·1' in a connected state.

[0047] 6(b), a plurality of screw holes are also provided on the left side surface 12. Among these screw holes, front screw holes 121·121 are provided nearer the front surface 15 for screwing the electric device 1 to the common fixing means 2 or the rack fixing means 3. In addition, rear screw holes 122 are provided nearer the rear surface 16 than the front screw holes 121·121 for screwing the electric device 1 to the device-side fixing part 22 of the common fixing means 2 when two electric devices 1·1 are attached in a connected state. However, the rear screw hole 122 on the left side surface 12 is provided closer to the front surface 15 than the rear screw hole 112 on the right side surface 11 .

[0048] As shown in FIG. 7(a), the top surface 14 has no screw holes. However, as shown in Figure 7 (b), a plurality of connecting screw holes 131·131' for connecting two electric devices 1·1 are provided on the bottom surface 13 of the electric device 1. When the two electric devices 1·1' are connected to each other, the shared fixing parts 21 of the shared fixing means 2 are screwed into these connecting screw holes 131·131'. The connecting screw holes 131 and 131' include a connecting screw hole 131 closer to the front surface 15 and a connecting screw hole 131' closer to the rear surface 16, with one on each side of the right side surface 11 and the left side surface 12.

[0049] When the electrical device 1 is installed alone, depending on the arrangement of the electrical device 1, the front screw holes 111·111 on the right side 11 and the front screw holes 121·121 on the left side 12 may be used to screw in the common fixing means 2 or the rack fixing means 3. For example, as shown in FIG. 2(a), when the electrical device 1 is mounted on the left side of the storage section S when viewed from the front, the device side fixing portion 22 of the common fixing means 2 is screwed into the front screw holes 111·111 on the right side surface 11, and the device side fixing portion 32 of the rack fixing means 3 is screwed into the front screw holes 121·121 on the left side surface 12.

[0050] On the other hand, as shown in Figure 2(b), when the electrical device 1 is attached to the right side of the storage section S when viewed from the front, the device side fixing portion 32 of the rack fixing means 3 is screwed into the front screw holes 111-111 on the right side surface 11, and the device side fixing portion 22 of the common fixing means 2 is screwed into the front screw holes 121-121 on the left side surface 12. In either case, the shared fixing portion 21 of the shared fixing means 2 and the rack side fixing portion 31 of the rack fixing means 3 are fixed so as to face outward.

[0051] 3(a), when two electric devices 1·1 are mounted in a connected state, the device side fixing parts 31 of the rack fixing means 3 are screwed into the front screw holes 111·111 on the right side surface 11 and the front screw holes 121·121 on the left side surface 12. In other words, two rack fixing means 3 are used. In this case, the shared fixing portions 21 of the shared fixing means 2 are screwed into the rear screw holes 112·112 on the right side surface 11 and the rear screw holes 122·122 on the left side surface 12. That is, two shared fixing means 2 are used.

[0052] 3(b), the device side fixing part 22 of the common fixing means 2 is screwed into the rear screw holes 122·122 on the left side surface 12 of the left electric device 1. In addition, the common fixing part 21 of the common fixing means 2 is screwed into the connecting screw hole 131 near the front surface 15 on the bottom surface 13 of the left electric device 1, and is screwed into the connecting screw hole 131 near the front surface 15 on the bottom surface 13 of the right electric device 1'.

[0053] Also, the device side fixing portion 22 of the shared fixing means 2 is screwed into the rear screw holes 112·112 on the right side surface 11 of the right-side electric device 1'. In addition, the shared fixing portion 21 of the shared fixing means 2 is screwed into the connecting screw hole 131' near the back surface 16 on the bottom surface 13 of the right-side electric device 1', and is screwed into the connecting screw hole 131' near the back surface 16 on the bottom surface 13 of the left-side electric device 1.

[0054] As described above, the two electric devices 1·1' are fixed with screws by two common fixing means 2·2 arranged in parallel with no gaps. As a result, when looking at only one of the electric devices 1, it is fixed by two screws spaced a certain distance apart in the front-to-rear direction, while when looking at both electric devices 1·1', it is fixed by four screws arranged in a rectangular shape. Therefore, the electric devices 1·1' are difficult to move not only in the direction in which they are pulled apart, but also in the rotational direction in which only the front sides 15·15 are pulled apart. In addition, since the two common fixing means 2·2 are arranged in parallel with no gap therebetween, the electric devices 1·1' are also less likely to move in the direction in which they are sheared relative to one another.

[0055] As a result, the two electrical devices 1·1' can be firmly connected together by means of the two common fixing means 2·2. Furthermore, when two common fixing means 2·2 are arranged with a gap between them, it is preferable to use two or more screws to fix the common fixing means 2 to the bottom surface 13 of each electrical device 1·1', from the standpoint of preventing movement in the shear direction.

[0056] As described above, with the mounting structure for the electrical device 1 of the present invention, when one electrical device 1, one common fixing means 2, and one rack fixing means 3 are made into one set, when the electrical device 1 is mounted in a standalone state, all of the contents of one set can be used, and when two electrical devices 1·1' are mounted in a connected state, all of the contents of both sets can be used.

[0057] 『Variation 1』 The present invention is not limited to the above embodiment, and other embodiments may be adopted. Note that the same reference numerals are used to designate parts common to the embodiments shown in Figures 1 to 7, and descriptions thereof will be omitted. For example, the mounting structure 101 for an electric device shown in Figures 8(a) and (b) is configured such that the depth direction of the electric device 1 is longer than that of the electric device 1 shown in Figure 5. Also, the right side surface 11 and the left side surface 12 are provided with heat dissipation holes 17, 17..., so that heat generated from the internal electric components can be dissipated to the outside.

[0058] In this modified example, when two electric devices 1·1' are connected, the two shared fixing means 2·2' are configured to be screwed to the rear surface 16 and bottom surface 13, and the rear surface 16 and top surface 14 of each electric device 1·1'. Also, on the rear surface 16, the device side fixing parts 21·21 of the two shared fixing means 2·2 are overlapped and screwed to each other with a common screw. Furthermore, the positions of the inlet, outlet, connecting connectors, etc. are adjusted so that the shared fixing part 21 of the shared fixing means 2 does not interfere with the connecting part 161 on the rear surface 16.

[0059] With this modified example, even if heat dissipation holes 17·17... are provided on the right side surface 11 and the left side surface 12 of the electric device 1, the shared fixing means 2 does not block the heat dissipation holes 17·17.... Furthermore, even with this embodiment, the two electric devices 1·1' can be firmly connected together using the two shared fixing means 2·2.

[0060] 『Variation 2』 In the present invention, other configurations may also be adopted. Note that the same reference numerals are used to designate the same parts as those in the configurations shown in Figures 1 to 7, and the description thereof will be omitted. 9(a), the electric device 1 of this modified example has heat dissipation holes 17·17... on the right side 11 and left side 12 of the electric device 1, and air intake holes 18·18... on the bottom surface 16. By providing the air intake holes 18·18..., heat generated from internal electric components can be discharged to the outside by being carried by air convection as it enters the inside through the air intake holes 18·18... and is discharged through the heat dissipation holes 17·17....

[0061] In the electrical device mounting structure 102 of this modified example, when connecting two electrical devices 1, 1', as in Figures 1 to 7, the device side fixing portion 22 of the shared fixing means 2 is screwed into the rear screw holes 122, 122 on the left side surface 12 of the left electrical device 1, and the device side fixing portion 22 of the shared fixing means 2 is screwed into the rear screw holes 112, 112 on the right side surface 11 of the right electrical device 1'.

[0062] However, as shown in FIG. 9(b), this embodiment differs from the embodiments shown in FIGS. 1 to 7 in that the common fixing portion 21 of the common fixing means 2 is fixed to the rear surface 16 of each of the electric devices 1·1′ with a screw. In this configuration, the positions of the inlets, outlets, connecting connectors, etc. are adjusted so that the shared fixing portion 21 of the shared fixing means 2 does not interfere with the connection portion 161 on the back surface 16, and an avoidance hole 19 is provided in the shared fixing portion 21 to avoid interference with the connection portion 161.

[0063] In this modified example, even if the right side surface 11 and the left side surface 12 of the electric device 1 have heat dissipation holes 17·17... and the air intake holes 18·18... are provided on the bottom surface 16, the shared fixing means 2 does not block the heat dissipation holes 17·17... and the air intake holes 18·18.... Even in this embodiment, the two electric devices 1·1' can be firmly connected together by using the two shared fixing means 2·2.

[0064] 『Variation 3』 Other configurations may also be adopted for preventing blockage of the heat dissipation holes 17·17... and the air intake holes 18·18.... The same reference numerals are used to designate parts common to the configurations shown in Figures 1 to 7, and descriptions thereof will be omitted. For example, in the electrical device mounting structure 103 shown in Figure 10, when two electrical devices 1 and 1' are connected, as in Figures 1 to 7, the device side fixing portion 22 of the shared fixing means 2 is screwed into the rear screw holes 122 / 122 on the left side surface 12 of the left electrical device 1, and the device side fixing portion 22 of the shared fixing means 2 is screwed into the rear screw holes 112 / 112 on the right side surface 11 of the right electrical device 1'.

[0065] 1 to 7 in that the shared fixing portion 21 of the shared fixing means 2 is fixed to the top surface 14 of each of the electric devices 1·1′ with a screw. In this modified example, even if the right side surface 11 and the left side surface 12 of the electric device 1 have heat dissipation holes 17·17... and the air intake holes 18·18..., the shared fixing means 2 does not block the heat dissipation holes 17·17... and the air intake holes 18·18.... In addition, since there is no need to provide the avoidance hole 19 in the shared fixing portion 21 of the shared fixing means 2 as in the embodiment of Fig. 9, it is possible to prevent a decrease in the strength of the shared fixing means 2. Even in this embodiment, the two electric devices 1·1' can be firmly connected together using the two shared fixing means 2·2.

[0066] In the present invention, in addition to the above-mentioned configuration, for example, the device-side fixing part 22 of the shared fixing means 2 can be screwed to the right side surface 11 or the left side surface 12, and the shared fixing part 21 can be screwed to the front surface 15 of the electric device 1 (not shown). In this case, the shared fixing part 21 can be provided with an avoidance hole 19 for avoiding interference with the operation part 151 and the display part 152.

[0067] As described above, with the mounting structure for electrical equipment and the electrical equipment of the present invention, no unnecessary parts are generated, whether the electrical equipment is mounted in a single state or in a state where two electrical equipment are connected together, and one electrical equipment, one common fixing means, and one rack fixing means are always used. Therefore, it is possible to manufacture and sell in units of one set, which is economical as there is no loss in manufacturing and management. Furthermore, no unnecessary parts that need to be discarded are generated, which reduces the impact on the environment, regardless of which of the above mounting states is selected.

[0068] The present invention is generally configured as described above, but the present invention is by no means limited to the illustrated embodiment, and various modifications are possible within the scope of the claims. For example, the common fixing means 2 and the rack fixing means 3 may be made of resin such as fiber reinforced resin, other than metal. The common fixing means 2 may be provided with a reinforcing rib that protrudes forward from the surface of the common fixing portion 21. The effects of the present invention can be achieved in any of the above embodiments. [Explanation of symbols]
