Installation of electrical equipment may be subject to various restrictions. For example, when the weight of an electric device exceeds the weight limit stipulated by laws and regulations, the number of workers who carry or support the electric device increases. That is, the weight of the electrical equipment can be a constraint on the installation of the electrical equipment. For example, when the wiring connected to the electric device is pulled out from the wall of the installation destination, there are restrictions on the wiring routing in the installation work. Further, in addition to the worker who supports the electric equipment, a worker who arranges the wiring is required. That is, the wiring of the electrical equipment can be a constraint on the installation of the electrical equipment. It is required to facilitate the installation of electrical equipment by reducing the restrictions on the installation of electrical equipment.

As shown in FIGS. 1 and 2, the electric device case 100 according to the embodiment includes a housing 10 and a support 20. The housing 10 houses the electrical device 30 inside. It can be said that the housing 10 has an internal space for accommodating the electric device 30. The support 20 is attached to the wall 50 (see FIG. 7A and the like) to support the housing 10. As a result, the electrical device 30 is installed on the wall 50. In this embodiment, gravity acts in the negative direction of the Y-axis. That is, the negative direction of the Y-axis corresponds to the vertical direction (vertically downward).

The electric device 30 may include, for example, a power conversion device such as a power conditioner. The electric device 30 may include a power supply device such as a storage battery or a fuel cell. The electric device 30 is not limited to these examples, and may include various devices.

The housing 10 may be configured to contain a metal such as aluminum. The housing 10 has a box shape that opens on the positive side of the Z axis. The surface of the housing 10 on the positive side of the Z axis is also referred to as the front surface. The surface of the housing 10 on the negative side of the Z axis, which is located on the opposite side of the front surface, is also referred to as a back surface. The housing 10 has a back surface portion 12 located on the back surface side.

The negative side of the Y-axis of the housing 10, that is, the vertically downward side is also referred to as a bottom surface. The housing 10 further has a bottom surface portion 13 located on the bottom surface side. The side of the housing 10 in the positive direction of the Y-axis, that is, the surface opposite to the bottom surface is also referred to as an upper surface. The housing 10 further has an upper surface portion 14 located on the upper surface side.

The surfaces of the housing 10 on the positive and negative directions of the X-axis are also referred to as side surfaces. The housing 10 further has a side surface portion 11 located on the side surface side. The side surface portion 11 includes a first side surface portion 11a located on the positive side of the X-axis and a second side surface portion 11b located on the negative side of the X-axis.

It can be said that the internal space of the housing 10 is partitioned by the side surface portion 11, the back surface portion 12, the bottom surface portion 13, and the top surface portion 14 that form a box shape.

The housing 10 may further include a bottom cover 15 that covers the bottom surface portion 13 from the bottom surface side. The upper surface portion 14 may have fins that project outward. The fins can act as a heat sink. The side surface portion 11 may have ribs that project outward. The ribs can increase the strength of the side surface portion 11. The housing 10 is not limited to the shape illustrated in FIG. 1, and may have various other shapes.

The housing 10 further includes a first protruding portion 16a that protrudes outward from the first side surface portion 11a on the side in the positive direction of the X-axis. The housing 10 further includes a second protruding portion 16b that projects outward from the second side surface portion 11b on the side in the negative direction of the X-axis, that is, outward. The housing 10 further includes a regulating portion 17 projecting outward from the side surface portion 11. The housing 10 is further provided with a support fastening portion 18 for fastening the housing 10 to the support 20 by a fastening member such as a screw on the side surface portion 11.

The support 20 may be configured to include a metal such as stainless steel. The support 20 includes a back plate 22 located along the wall 50 when attached to the wall 50. The back plate 22 has a plurality of wall mounting holes 26 for mounting the support 20 to the wall 50. The wall mounting hole 26 may be located near the center of the back plate 22, near the sides of the back plate 22, or near the corners of the back plate 22. The back plate 22 has an opening 27 for passing the wiring 60 (see FIG. 6 and the like) drawn from the wall 50. The opening 27 is partitioned by an opening end 27a.

The support 20 further includes a side plate 21 projecting to the front side from each of the two sides located on the side surface side of the four sides of the back plate 22. The side plate 21 includes a first side plate 21a located on the positive side of the X-axis and a second side plate 21b located on the negative side of the X-axis. The first side plate 21a and the second side plate 21b are provided with a first support portion 23a and a second support portion 23b at the end portions on the upper surface side, respectively. The first support portion 23a and the second support portion 23b are also collectively referred to as the support portion 23.

The support portion 23 may be formed by cutting out an end portion of the side plate 21. As shown in FIG. 3, the support portion 23 may have a bent portion 231 formed by bending a notched end portion outward. The bent portion 231 forms a curved surface along a shape in which the end portion of the side plate 21 is cut out. The side plate 21 further includes a side plate notch 24 formed by notching from the front side. The side plate 21 further includes a housing fastening hole 25 through which a fastening member for fastening the housing 10 to the support 20 is passed.

As shown in FIG. 3, when the housing 10 is attached to the support 20, the protruding portion 16 of the housing 10 is fitted into the support 23 of the support 20. In this case, a force against gravity acts from the support portion 23 to the protruding portion 16. As a result, the housing 10 is supported by the support 20 against gravity.

Since the support portion 23 has the bent portion 231 so that the protruding portion 16 is supported by the curved surface formed by the bent portion 231. That is, the area of the portion that supports the protruding portion 16 increases. By increasing the area supporting the protrusion 16, the drag force per unit area applied to the protrusion 16, that is, the pressure applied to the protrusion 16 is reduced. As a result, the protrusion 16 is less likely to be damaged.

In the present embodiment, the first protruding portion 16a and the second protruding portion 16b are located on an axis parallel to the X axis. In this case, the housing 10 is configured to be tiltable in the YZ plane with the axis connecting the first protrusion 16a and the second protrusion 16b as a fulcrum. The axis connecting the first protrusion 16a and the second protrusion 16b is also referred to as a tilt axis. In other words, the housing 10 is configured to be tiltable with the tilt axis as a fulcrum.

The outer shape of the protruding portion 16 may be cylindrical or may have a cylindrical shape having a missing portion. The protrusion 16 illustrated in FIG. 3 has a shape in which the protrusion cutout 161 is formed by cutting out a part of the cylindrical shape. In other words, the protrusion 16 is configured such that the outer shape seen from the direction along the tilt axis includes at least a part of an arc centered on the tilt axis. It can be said that the outer shape of the protrusion 16 in the cross section orthogonal to the tilt axis includes at least a part of an arc centered on the tilt axis. The outer shape of the support portion 23 when the support portion 23 is viewed from the direction along the tilt axis includes at least a part of an arc. In the present embodiment, it is assumed that the outer shape of the support portion 23 when viewed from the direction along the tilt axis is U-shaped. By doing so, the frictional force acting between the protrusion 16 and the support 23 when the housing 10 is tilted with the protrusion 16 as a fulcrum can be reduced. As a result, the protruding portion 16 and the supporting portion 23 are less likely to be damaged.

The housing 10 has a center of gravity. The Z coordinate of the center of gravity of the housing 10 is larger than the Z coordinate of the position where the protrusion 16 is provided. That is, the center of gravity of the housing 10 is located on the opposite side of the back plate 22 of the support 20 when viewed from the protruding portion 16. In this case, the gravity acting on the center of gravity of the housing 10 has a component in the negative direction of the Z axis, that is, in the direction approaching the back plate 22. As a result, in a state where the housing 10 is suspended by the protrusion 16 by gravity, the housing 10 can be supported by a drag acting in the positive direction of the Z-axis from the back plate 22.

The support 20 supports the housing 10 with two support portions 23 into which the protruding portions 16 of the housing 10 are fitted. Further, the housing 10 is supported by the back plate 22 of the support 20 in a state where the housing 10 is suspended by the protrusion 16 by gravity. That is, the support 20 supports the housing 10 at at least three points of the two support portions 23 and the back plate 22. As a result, the posture of the housing 10 is stabilized by gravity.

In the configuration illustrated in FIG. 2, the housing 10 is moved to a position stable by gravity. That is, the housing 10 is suspended from the support 20 by gravity. In this case, the restricting portion 17 of the housing 10 is located inside the recess formed in the side plate 21 by the side plate notch 24 of the support 20, as shown in FIG. In other words, the housing 10 and the support 20 are configured so that the distance from the protrusion 16 to the regulation portion 17 on the side surface portion 11 and the distance from the support portion 23 to the side plate notch 24 on the side plate 21 are equal. To.

The regulating unit 17 regulates the movement of the housing 10 in each of the vertically upward direction and the vertically downward direction in the state of being inserted into the recess. By restricting the movement of the housing 10 in the vertical direction, it becomes difficult for the housing 10 to move in the vertical direction when an external force is applied to the housing 10 or the housing 10 vibrates. Since the housing 10 is difficult to move in the vertical direction, the protruding portion 16 is difficult to come off from the support portion 23. As a result, even if vibration or an external force is applied to the housing 10, the support 20 can stably support the housing 10. In other words, the housing 10 is not fixed to the support 20 by the support fastening portion 18 or the like, and even if it is simply suspended from the support 20, it is difficult for the housing 10 to fall off from the support 20 due to the application of an external force.

As shown in FIG. 5, the housing 10 can be tilted to the front side with the tilting axis represented by C as a fulcrum by applying an external force. When the housing 10 is tilted, friction is generated between the protruding portion 16 and the supporting portion 23. When the bent portion 231 provided on the support portion 23 supports the protruding portion 16 with a curved surface, the drag force per unit area acting from the supporting portion 23 to the protruding portion 16 is reduced. By reducing the drag force per unit area, the frictional force acting between the projecting portion 16 and the bending portion 231 is reduced. As a result, the protruding portion 16 and the supporting portion 23 are less likely to be worn.

As shown in FIG. 6, the housing 10 further includes a wiring duct 19 on the back side. The wiring duct 19 is also simply referred to as a duct. The wiring duct 19 defines an opening that communicates the inside and the outside of the housing 10 on the back surface portion 12. The wiring 60 connected to the electric device 30 is routed from the outside on the back surface 12 side of the housing 10 to the electric device 30 located inside the housing 10 through an opening partitioned by the wiring duct 19. Ru. The wiring duct 19 has a sealing surface 194 on the back surface side, that is, on the side facing the wall 50 or the support 20. The sealing surface 194 is configured to come into contact with the wall 50 or the support 20 when the housing 10 is fixed to the support 20. The sealing surface 194 may come into contact with the wall 50 or the support 20 via a sealing member such as packing. By doing so, it becomes difficult for water, dust, or the like to enter the inside of the housing 10.

As shown in FIGS. 7A, 7B and 7C, it is assumed that the wiring 60 is drawn out of the wall 50 through a wall hole 52 partitioned by an inner wall 52a of the wall 50. The support 20 is attached to the wall 50 so that the position of the opening 27 matches the position of the wall hole 52. The wiring 60 hangs vertically downward (in the negative direction of the Y axis) along the wall 50 by gravity as shown in FIG. 7A when it is not connected to the electric device 30. When the housing 10 is attached to the support 20 in this state, the wiring 60 may be sandwiched between the housing 10 and the support 20 or the wall 50 and damaged.

It is necessary to carry out the installation work of the housing 10 so that the wiring 60 is not sandwiched between the housing 10 and the support 20 or the wall 50. As shown in FIG. 7A, the lower portion of the housing 10 is supported by the worker away from the support 20 or the wall 50. The white arrows indicate the direction of the external force acting on the housing 10 to separate the lower portion of the housing 10 from the support 20 or the wall 50. In this case, the upper portion of the housing 10 is supported by the worker so that the protruding portion 16 is fitted into the support portion 23 and is brought close to the support 20. That is, the housing 10 is supported so as to be inclined with respect to the support 20 in the side view. In this state, the protruding portion 16 is fitted into the support portion 23. It can be said that the housing 10 is tilted so that the lower portion of the housing 10 is separated from the support 20 with the tilting axis as a fulcrum.

As shown in FIG. 7B, the wiring 60 is inserted into the wiring duct 19 in a state where the housing 10 is tilted so that the lower portion of the housing 10 is separated from the support 20. The white arrows indicate the direction of the external force acting on the housing 10 to keep the lower part of the housing 10 away from the support 20 or the wall 50. The work of connecting the wiring 60 to the electric device 30 housed in the housing 10 may be performed while the housing 10 is tilted with respect to the support 20.

As shown in FIG. 7C, after the wiring 60 is inserted into the wiring duct 19 or the housing 10, the housing 10 is tilted to a stable position by gravity. That is, the housing 10 is suspended from the support 20 by gravity. In this case, the housing 10 is tilted so that the lower portion of the housing 10 approaches the wall 50 and the wiring duct 19 abuts on the support 20 or the wall 50. The white arrows represent the gravity acting in the tilting direction of the housing 10 that tilts with the tilting axis as a fulcrum. Further, the housing 10 is fixed to the support 20 at the support fastening portion 18 and the like. The work of connecting the wiring 60 to the electric device 30 housed in the housing 10 may be performed while the housing 10 is stable to gravity or fixed to the support 20.

The installation work of the housing 10 carried out in the embodiment illustrated in FIGS. 7A, 7B and 7C can be carried out by two workers because the housing 10 can be tilted with respect to the support 20. It can be said that there is. The work procedure in this case is exemplified below as a method of installing the electric device case 100 according to the embodiment.
(A1) Two workers fit the protruding portion 16 of the housing 10 into the support portion 23 of the support body 20 and hang the housing 10 on the support body 20. At this time, the worker hangs on the support 20 with the housing 10 tilted so that the wiring duct 19 does not hit the wiring 60.
(A2) The housing 10 is moved from the support 20 so that one of the two workers can create a space for wiring work between the side of the back surface 12 of the housing 10 and the wall 50. Maintain the tilted state so that it separates.
(A3) Another worker carries out the wiring work.
(A4) After the wiring work, the worker who supported the housing 10 tilts the housing 10 to a stable position by gravity. That is, the worker puts the housing 10 in a state of being suspended from the support 20.
(A5) A worker fixes the housing 10 to the support 20.

As a comparative example, a case where the housing 10 cannot be tilted with respect to the support 20 can be considered. The case installation work according to the comparative example can be carried out by three workers as follows.
(B1) The housing 10 is moved from the support 20 so that two of the three workers can create a space for wiring work between the side of the back surface 12 of the housing 10 and the wall 50. Support at predetermined intervals.
(B2) The remaining one of the three workers carries out the wiring work.
(B3) After the wiring work, the worker fixes the housing 10 to the support 20.

As described above, according to the present embodiment, the wiring work can be carried out by a small number of personnel as compared with the comparative example. As a result, the installation work of the electric device case 100 can be facilitated.

As shown in FIG. 8A, the wiring duct 19 may have a duct notch 192 on the negative side of the Y-axis, i.e., on the vertically downward side. The wiring 60 is represented by a solid line and a chain double-dashed line. The wiring 60 represented by the alternate long and short dash line corresponds to a portion located in the wall 50. The wiring 60 represented by the solid line corresponds to the portion drawn out from the wall 50.

The wiring 60 drawn out from the wall 50 hangs vertically downward (in the negative direction of the Y axis) along the wall 50 due to gravity in a state where it is not inserted into the housing 10. Since the wiring duct 19 has the duct notch 192, the wiring duct 19 does not hit the hanging wiring 60 even when the housing 10 is suspended from the support 20 by gravity. By doing so, the housing 10 is less likely to damage the wiring 60. That is, even before the wiring 60 is inserted into the housing 10, the worker does not need to support the housing 10 so as to be separated from the support 20, and the housing 10 is suspended from the support 20. Can be left in the lowered state. As a result, the degree of freedom of the installation work can be increased, and the installation work can be facilitated.

As shown in FIG. 8B, the wiring duct 19 may further have a duct cover 191 that closes the duct notch 192. The duct cover 191 is also simply referred to as a cover. The duct cover 191 is configured to be removable from the wiring duct 19. When the duct cover 191 is removed from the wiring duct 19, the wiring duct 19 is unlikely to hit the wiring 60, as shown in FIG. 8A. When the duct cover 191 is attached to the wiring duct 19 and closes the duct notch 192, the sealing surface 194 abuts on the wall 50 or the support 20, and the duct cover 191 closes the duct notch 192, whereby the wiring duct 19 Can be sealed to the outside. By doing so, it becomes difficult for water, dust, or the like to enter the inside of the housing 10 from the wiring duct 19. As a result, the electric device 30 housed inside the housing 10 can be protected from water, dust, and the like.

As shown in FIGS. 9A, 9B and 9C, it is assumed that the wiring 60 is drawn out of the wall 50 through a wall hole 52 partitioned by an inner wall 52a of the wall 50. The support 20 is installed on the wall 50 in the same configuration as illustrated in FIGS. 7A-7C.

As shown in FIG. 9A, the wiring 60 hangs vertically downward (in the negative direction of the Y axis) along the wall 50 due to gravity when it is not connected to the electric device 30. Since the wiring duct 19 has the duct notch 192, the wiring duct 19 hangs down even when the housing 10 is not supported by the worker but is simply suspended from the support 20 by gravity. It does not hit the wiring 60. In this case, the worker can hang the housing 10 on the support 20 without worrying about the collision between the wiring duct 19 and the wiring 60, and suspend the housing 10 on the support 20 before the wiring work. Can be left in a state of being. As a result, the degree of freedom of the installation work can be increased, and the installation work can be facilitated.

As shown in FIG. 9B, the housing 10 is tilted so that the lower portion of the housing 10 is separated from the support 20. In this state, the wiring 60 is inserted into the wiring duct 19. The white arrows indicate the direction of the external force acting on the housing 10 to separate the lower portion of the housing 10 from the support 20 or the wall 50. The work of connecting the wiring 60 to the electric device 30 housed in the housing 10 may be performed while the housing 10 is tilted with respect to the support 20.

As shown in FIG. 9C, after the wiring 60 is inserted into the wiring duct 19 or the housing 10, the housing 10 is moved to a stable position by gravity. In this case, the housing 10 is tilted so that the lower portion of the housing 10 approaches the wall 50 and the wiring duct 19 abuts on the support 20 or the wall 50. The white arrows represent the gravity acting in the tilting direction of the housing 10 that tilts with the tilting axis as a fulcrum. Further, the housing 10 is fixed to the support 20 at the support fastening portion 18 and the like. The work of connecting the wiring 60 to the electric device 30 housed in the housing 10 may be performed while the housing 10 is stable to gravity or fixed to the support 20.

The installation work of the housing 10 carried out in the embodiment illustrated in FIGS. 9A, 9B and 9C can be carried out by two workers because the housing 10 can be tilted with respect to the support 20. It can be said that there is. The work procedure in this case is exemplified below as a method of installing the electric device case 100 according to the embodiment.
(C1) Two workers fit the protruding portion 16 of the housing 10 into the support portion 23 of the support body 20 and hang the housing 10 on the support body 20. At this time, the worker can hang the housing 10 on the support 20 without worrying about whether the wiring duct 19 hits the wiring 60.
(C2) The housing 10 is moved from the support 20 so that one of the two workers can create a space for wiring work between the side of the back surface 12 of the housing 10 and the wall 50. Tilt to separate and maintain that state.
(C3) Another worker carries out the wiring work.
(C4) After the wiring work, the worker who supported the housing 10 tilts the housing 10 to a stable position by gravity. That is, the worker puts the housing 10 in a state of being suspended from the support 20.
(C5) The worker fixes the housing 10 to the support 20.
(C6) The worker attaches the duct cover 191 to the wiring duct 19.

Also in the embodiments exemplified in FIGS. 9A to 9C, the wiring work can be carried out with a smaller number of personnel as compared with the comparative example.

When the wiring duct 19 has a duct notch 192, the wiring duct 19 is unlikely to hit the wiring 60 regardless of whether the housing 10 is tiltable with respect to the support 20. Therefore, even when the housing 10 is not tiltable with respect to the support 20, the wiring duct 19 can be facilitated by having the duct notch 192.

As shown in FIG. 10, the housing 10 attached to the support 20 is covered with the front cover 40. The front cover 40 has a housing fastening hole 44 on the side surface. The housing 10 has a cover fastening portion 46 on the side surface portion 11. The housing fastening hole 44 is fastened to the cover fastening portion 46 by a fastening member such as a screw.
