[0009] (Embodiment) Below, a cabinet U1 and a distribution board U10 according to an embodiment will be described using the drawings. However, the following embodiment is merely one of various embodiments of the present disclosure. The following embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. Furthermore, each figure described in the following embodiment is a schematic diagram, and the ratios of the sizes and thicknesses of the components in the figures do not necessarily reflect the actual dimensional ratios.

[0010] In addition, in each drawing, the X-axis direction is defined as the left-right direction, the Y-axis direction as the front-rear direction (depth direction), and the Z-axis direction as the up-down direction. Furthermore, the positive direction of the X-axis direction is defined as the right, the positive direction of the Y-axis direction as the back, and the positive direction of the Z-axis direction as the up. The X, Y, and Z axes are perpendicular to each other. However, these directions are merely examples and are not intended to limit the directions in which the cabinet U1 and the distribution board U10 are used. Furthermore, the arrows indicating each direction in the drawings are merely shown for explanatory purposes and have no substance.

[0011] The X-axis direction is also referred to as the first direction D1, the Y-axis direction as the second direction D2, and the Z-axis direction as the third direction D3.

[0012] (overview) As shown in FIGS. 1 to 3, the cabinet U1 of this embodiment includes a base 1, a cover 2, and a handle 3. The base 1 has a pair of first side walls 14 facing each other in a first direction D1, a connecting portion (a bottom wall 13 and a pair of side walls 15) connecting the pair of first side walls 14 to each other, an opening 12 provided between the pair of first side walls 14, and a first hook portion 1a. The cover 2 has a pair of second side walls 24 facing each other in the first direction D1 and a bottom wall 23 connecting the pair of second side walls 24 to each other. The bottom wall 23 covers the opening 12 of the base 1 in a second direction D2 perpendicular to the first direction D1. The handle 3 has a second hook portion 32. The handle 3 is disposed in a space SP1 (see FIG. 5) surrounded by the base 1 and the cover 2. The handle 3 is held by the cover 2 so as to be rotatable about an axis along the first direction D1. The bottom wall 23 has a through-hole 230 exposing the handle 3 in an area adjacent to the second side wall 24. The rotation positions of the handle 3 include a first rotation position (the rotation position of the handle 3 in FIG. 9) where the second hook portion 32 of the handle 3 is hooked onto the first hook portion 1a of the base 1, and a second rotation position (the rotation position of the handle 3 in FIG. 10) where the first hook portion 1a and the second hook portion 32 are released from each other.

[0013] According to the above configuration, the base 1 and the cover 2 can be released from the connection by rotating the handle 3 from the first rotation position to the second rotation position. The handle 3 functions as an operating unit that accepts an operation to release the connection between the base 1 and the cover 2. Compared to when the operating unit is provided on the side of the cabinet U1, the operating unit can be easily operated even if the cabinet U1 is installed in a narrow space. Therefore, the workability of removing the cover 2 from the base 1 can be improved.

[0014] Furthermore, according to the above configuration, the handle 3 is housed in the space SP1 surrounded by the base 1 and the cover 2, so the appearance of the cabinet U1 can be made neater compared to when the handle 3 is provided outside the space SP1.

[0015] Specifically, the attachment of the base 1 and the cover 2 is performed as follows. With the handle 3 held by the cover 2, the handle 3 is attached to the base 1 by a recessed / protruding engagement (the engagement of the recessed portion 1b with the protruding portion 32b) as shown in FIG. 9. This attaches the cover 2 to the base 1 via the handle 3. Furthermore, as shown in FIG. 10, the recessed / protruding engagement is released, and the handle 3 is removed from the base 1. This releases the attachment of the cover 2 to the base 1 via the handle 3.

[0016] The cabinet U1 may be provided with at least one handle 3. In the illustrated example, the cabinet U1 is provided with a pair of handles 3.

[0017] 1, the distribution board U10 of this embodiment includes a cabinet U1 and a wiring fixture 4. The wiring fixture 4 is disposed in a space SP1 surrounded by the base 1 and the cover 2. The wiring fixture 4 is, for example, a breaker.

[0018] The distribution board U10 may include at least one wiring fixture 4. In the example shown in FIG.

[0038] The base portion 16 is connected to the first side wall 14. The base portion 16 faces the end of the extension portion 18 on the negative side of the Z axis. The base portion 16 is spaced apart from the extension portion 18 in the Y axis direction. The base portion 16 has an inclined surface 160 (see FIG. 7). When viewed from the X axis direction, the inclined surface 160 is a surface that is higher (towards the positive side of the Z axis) as it moves towards the positive side of the Y axis.

[0039] The wall portion 17 has a plate-like shape. The thickness direction of the wall portion 17 is along the X-axis direction. The wall portion 17 protrudes from the extension portion 18. More specifically, the wall portion 17 protrudes toward the negative side of the Y-axis from the end of the extension portion 18 opposite the end connected to the first side wall 14. The wall portion 17 is connected to the first side wall 14 via the extension portion 18. The wall portion 17 protrudes toward the negative side of the Y-axis with respect to the first side wall 14.

[0040] Furthermore, the wall portion 17 covers the base portion 16 from the X-axis direction. When viewed from the Y-axis direction, the base portion 16 is provided between the wall portion 17 and the first side wall .

[0041] Each of the multiple ribs 19 has a plate-like shape. The thickness direction of each of the multiple ribs 19 is along the Z-axis direction. Each of the multiple ribs 19 protrudes from the extension portion 18 to the negative side of the Y-axis. The multiple ribs 19 are arranged at intervals from one another in the Z-axis direction.

[0042] The space surrounded by the base 16, the wall 17, the extension 18, and the rib 19 is a recess 1b (see FIGS. 2 and 7) into which the second hook 32 (protrusion 32b) of the handle 3 is inserted when the handle 3 is in the first rotation position. The first hook 1a includes the recess 1b.

[0043] The first hook portion 1a is provided on the first side wall 14. More specifically, the first hook portion 1a is provided on the front end portion of the first side wall 14.

[0044] (3) Cover The cover 2 is a member made of, for example, resin or metal.

[0045] 2 and 3, the cover 2 has openings 21 and 22, a bottom wall 23, a pair of second side walls 24, a pair of side walls 25, a panel 26, and two handles 27. Overall, the cover 2 has a rectangular parallelepiped shape with the opening 22 on the rear surface.

[0046] The thickness direction of each of the pair of second side walls 24 is along the X-axis direction. The longitudinal direction of each of the pair of second side walls 24 is along the Z-axis direction. The pair of second side walls 24 face each other in the X-axis direction.

[0047] The thickness direction of each of the pair of side walls 25 is along the Z-axis direction. The longitudinal direction of each of the pair of side walls 25 is along the X-axis direction. The pair of side walls 25 face each other in the Z-axis direction.

[0048] One of the pair of side walls 25 connects the upper end portions of the pair of second side walls 24. The other of the pair of side walls 25 connects the lower end portions of the pair of second side walls 24.

[0049] The bottom wall 23 is shaped like a rectangular (rectangular or square) plate. The thickness direction of the bottom wall 23 is along the Y-axis direction. The bottom wall 23 covers the space surrounded by the pair of second side walls 24 and the pair of side walls 25 from the negative side (front side) of the Y-axis.

[0053] The opening 22 (see FIG. 3) opens the space surrounded by the pair of second side walls 24 and the pair of side walls 25 to the positive side (rear side) of the Y axis. In other words, the space is connected to the space behind and outside the cover 2 through the opening 22. The rear ends of the pair of second side walls 24 and the pair of side walls 25 form the inner edge of the opening 22.

[0054] The two handles 27 are provided on the negative side of the Y-axis of the bottom wall 23 of the cover 2. That is, the two handles 27 are provided on the front surface of the bottom wall 23. Each of the two handles 27 is shaped like a plate. Rearward-facing recesses 231 are provided on the left and right regions of each of the two handles 27 on the front surface of the bottom wall 23, and the handles 27 are partition plates provided between these two recesses 231. The thickness direction of each of the two handles 27 is along the left-right direction. An operator can grasp the handles 27 from the outside (the front of the cover 2). When the base 1 and the cover 2 are released from their attachment via the pair of handles 3, an operator can separate the cover 2 from the base 1 by grasping the two handles 27 and pulling the cover 2 forward.

[0055] 3 and 4, the cover 2 further has a pair of mounting portions T1. Each of the pair of mounting portions T1 includes a shaft portion 28, a first protective portion 29, and a second protective portion 2a.

The thickness direction of the second protective portion 2a is along the Z-axis direction. The second protective portion 2a is provided on the negative side of the Z-axis with respect to the shaft portion 28. The shaft portion 28 is provided between the first protective portion 29 and the second protective portion 2a.

[0060] (4) Handle The handles 3 are members made of, for example, resin or metal, and the pair of handles 3 are symmetrical with respect to a plane perpendicular to the X-axis.

[0061] The handle 3 is shaped like a plate with its thickness along the X-axis direction. When viewed from the Y-axis direction (second direction D2), the longitudinal direction of the handle 3 is along the Z-axis direction (third direction D3). When viewed from the Z-axis direction, the longitudinal direction of the handle 3 is along the Y-axis direction.

[0062] As shown in FIG. 4, the handle 3 has a handle body 31, a second hook portion 32, a connecting portion 33, and a protrusion .

[0063] When viewed from the X-axis direction, the handle body 31 has a trapezoidal shape.

[0064] The handle 3 has a hole (through-hole) 310. The hole 310 is provided in the handle body 31 of the handle 3.

[0065] The handle 3 has a groove 311. The groove 311 is provided at a position that becomes the upper surface of the handle main body 31 when the handle 3 is in the first rotation position (see FIG. 7).

[0066] The second hook portion 32 includes a protrusion 32b protruding from the handle body 31. The protrusion 32b protrudes from the end of the handle body 31 on the positive side of the Y axis toward the negative side of the Z axis when the rotation position of the handle 3 is at the first rotation position (see FIG. 7). The protrusion 32b has an inclined surface 320. When the rotation position of the handle 3 is at the first rotation position, the inclined surface 320 is a surface that is positioned higher on the positive side of the Y axis (toward the positive side of the Z axis) when viewed from the X axis direction.

[0067] The shape of the coupling part 33 is cylindrical. The axial direction of the coupling part 33 is along the X-axis direction. The coupling part 33 is provided at the end of the handle body 31 on the negative side of the Z-axis when the rotation position of the handle 3 is the first rotation position (see FIG. 7).

[0068] The protrusion 34 protrudes from the handle body 31. The protrusion 34 is provided at the end of the handle body 31 on the negative side of the Z axis when the rotation position of the handle 3 is the first rotation position (see FIG. 7). The protrusion 34 is adjacent to the connecting portion 33. The protrusion 34 protrudes further on the negative side of the Z axis than the connecting portion 33.

[0069] When the rotation position of the handle 3 is the first rotation position, the hole 310 and the groove portion 311 are provided on the positive side of the Z axis relative to the connecting portion 33.

[0070] (5) Fastener As shown in FIG. 4, the cabinet U1 further includes a pair of stoppers 5 (only one of which is shown in FIG. 4). The pair of stoppers 5 correspond one-to-one with the pair of handles 3. Each stopper 5 rotatably holds the corresponding handle 3. Furthermore, the pair of stoppers 5 correspond one-to-one with the pair of second side walls 24.

[0071] The fastener 5 has a cylindrical portion 51 and a cap 52 .

[0072] The tubular portion 51 has a cylindrical shape. The tubular portion 51 is inserted into the connecting portion 33 of the corresponding handle 3. Furthermore, the tubular portion 51 is fixed to the shaft portion 28 protruding from the corresponding second side wall 24 (see FIG. 7). As a result, the shaft portion 28 and the tubular portion 51 are connected to the connecting portion 33, and rotatably hold the handle 3. The handle 3 rotates around the connecting portion 33, the shaft portion 28, and the tubular portion 51.

[0073] The cap 52 is connected to the tip of the cylindrical portion 51. The cap 52 is disk-shaped and has a diameter larger than that of the cylindrical portion 51. The handle 3 is disposed between the cap 52 and the second side wall 24. The cap 52 prevents the handle 3 from falling off the cylindrical portion 51.

[0074] (6) Handle placement The handle 3 is held by the cover 2 by passing the shaft 28 through the inside of the connecting portion 33. In other words, the shaft 28 is a part that rotatably holds the handle 3 and serves as the center of rotation of the handle 3. The shaft 28 is provided on the second side wall 24. Therefore, the handle 3 is disposed adjacent to the second side wall 24.

[0075] When the rotation position of the handle 3 is the first rotation position, the handle 3 is disposed between the first protection part 29 and the second protection part 2a. The first protection part 29 and the second protection part 2a cover the handle 3 from the direction (Z-axis direction) intersecting the X-axis direction (first direction D1). In this way, the first protection part 29 and the second protection part 2a protect the handle 3.

[0076] 5, when the handle 3 is in the first rotation position, the second hook portion 32 of the handle 3 is located between the second side wall 24 corresponding to the handle 3 and the wall portion 17 of the holder H1 corresponding to the handle 3. That is, in the example shown in Fig. 5, the second side wall 24 is located on the positive side of the X-axis relative to the second hook portion 32, and the wall portion 17 is located on the negative side of the X-axis relative to the second hook portion 32.

[0077] As shown in FIG. 5, when the handle 3 is in the first rotation position, a part of the handle 3 (operation surface 312) is exposed to the outside through the through-hole 230 of the cover 2.

[0078] When the handle 3 is in the first rotation position, there is a gap 2301 in the Z-axis direction (third direction D3) between the inner edge of the through-hole 230 and the handle 3. The handle 3 has a groove 311 in an area facing the gap 2301. Therefore, an operator can insert a finger through the gap 2301 and rotate the handle 3 by placing the finger against the groove 311.

[0079] Preferably, the length of gap 2301 in the Z-axis direction is ½ or more (more preferably ⅔ or more) of the length of operation surface 312 in the X-axis direction.

[0080] (7) Installation and removal work Next, an example of the work of attaching the cover 2 to the base 1 and the work of removing the cover 2 from the base 1 will be described.

[0081] (7.1) Installation It is assumed that a pair of handles 3 are attached to the pair of second side walls 24 of the cover 2, respectively, in advance.

[0082] With each handle 3 in the first rotation position, the worker brings the end of the cover 2 on the positive side of the Y axis closer to the end of the base 1 on the negative side of the Y axis, and also brings the second hook portion 32 of each handle 3 closer to the first hook portion 1a of the base 1, as shown in Figure 7.

[0083] Next, the operator rotates the handle 3 from the first rotation position. For example, the operator may rotate the handle 3 to a position between the first rotation position and the second rotation position, as shown in Fig. 8. Alternatively, the operator may rotate the handle 3 to the second rotation position.

[0084] The worker pushes the handle 3 toward the positive side of the Y axis to rotate the handle 3 toward the first rotation position, while moving the cover 2 toward the positive side of the Y axis. As a result, the worker inserts the convex portion 32b of the second hook portion 32 into the concave portion 1b of the first hook portion 1a, as shown in Figure 9. When the convex portion 32b is inserted into the concave portion 1b, the rotation position of the handle 3 becomes the first rotation position.

[0085] The attachment of the cover 2 to the base 1 is completed by inserting the respective convex portions 32b of the pair of handles 3 into the corresponding concave portions 1b. That is, the cover 2 is attached to the base 1 via the pair of handles 3.

[0086] When the cover 2 is attached to the base 1 via the pair of handles 3, the protrusions 34 of the handles 3 contact the base 1, as shown in Figure 9. More specifically, the protrusions 34 contact the base portion 16 of the base 1.

[0087] At this time, the inner edge of the opening 12 on the front surface of the base 1 is inserted into the inner edge of the opening 22 on the rear surface of the cover 2 .

[0088] At this time, the plurality of ribs 19 of the holder H1 are in contact with the handle 3. The plurality of ribs 19 position the handle 3 in the first rotation position.

[0089] (7.2) Removal When removing the cover 2 from the base 1, the worker inserts his or her finger through the gap 2301 provided in the cover 2, places the finger in the groove 311, and rotates the handle 3 from the first rotation position shown in Fig. 9 to the second rotation position shown in Fig. 10. This removes the protrusion 32b from the recess 1b. In other words, the engagement between the first hook portion 1a and the second hook portion 32 is released.

[0090] When the handle 3 is rotated to a certain extent from the first rotation position and the hole 310 of the handle 3 is exposed to the outside of the cover 2, the operator can insert his / her hand or fingers into the hole 310 and rotate the handle 3.

[0091] When the handle 3 rotates from the first rotation position to the second rotation position, the protrusion 34 of the handle 3 pushes the base 1. Specifically, at this time, the protrusion 34 pushes the platform portion 16 of the base 1 in the positive direction of the Y axis.

[0092] When the handle 3 rotates from the first rotation position to the second rotation position, the protrusion 34 comes into contact with the base 1 before the convex portion 32b of the second hook portion 32 is removed from the concave portion 1b of the first hook portion 1a. Specifically, the protrusion 34 is in contact with the base 1 from the time the handle 3 is in the first rotation position.

[0093] When the handle 3 rotates from the first rotation position to the second rotation position, the protrusion 34 presses the base 1, and as a result, the protrusion 34 receives a reaction force from the base 1. The reaction force separates the cover 2 from the base 1. Therefore, the cover 2 can be easily removed from the base 1.

[0094] Even when the protrusions 34 push the base 1 and the cover 2 separates from the base 1, the inner edge of the opening 12 on the front of the base 1 remains inserted into the inner edge of the opening 22 on the rear of the cover 2, as shown in Figure 10. The worker then grasps the two handles 27 (see Figure 1) of the cover 2 and tilts the cover 2 toward himself. This removes the inner edge of the opening 12 on the front of the base 1 from the inner edge of the opening 22 on the rear of the cover 2.

[0095] As shown in FIG. 7, in the handle 3, the distance L1 between the tip of the protrusion 34 and the center of the coupling portion 33 is shorter than the maximum distance L2 between the center of the coupling portion 33 and the operation surface 312. Furthermore, the maximum distance L2 is approximately equal to the distance between the center of the coupling portion 33 and the groove portion 311. The distance L1 is shorter than the distance between the center of the coupling portion 33 and the groove portion 311. Therefore, when an operator rotates the handle 3 via the operation surface 312 or the groove portion 311, a large force can be applied from the protrusion 34 to the base 1 due to the principle of leverage.

[0096] (Modification of the embodiment) Modifications of the embodiment are listed below. The following modifications may be implemented in appropriate combination. Hereinafter, the configuration of the above-described embodiment will be referred to as a basic example.

[0097] The first hook portion 1a in the basic example includes a recess 1b into which the protrusion 32b of the second hook portion 32 is inserted. Alternatively, the first hook portion 1a may include a protrusion into which the recess of the second hook portion 32 is inserted. Similarly, in the basic example, the recess and protrusion of the coupling structure connected by fitting the recess and protrusion may be interchanged. Furthermore, instead of the recess and protrusion, the coupling structure may have another configuration, for example, it may be composed of a claw and a member on which the claw is hooked.

[0098] In the basic example, the front end of the base 1 is inserted inside the cover 2. Alternatively, the rear end of the cover 2 may be inserted inside the base 1.

[0099] In the basic example, when the rotation position of the handle 3 is the first rotation position (see FIG. 7), the coupling part 33 is provided on the negative side of the Z axis from the center of the handle 3. However, the position of the coupling part 33 is not particularly limited, and for example, the coupling part 33 may be provided on the positive side of the Z axis from the center of the handle 3.

[0100] The positions of the second hook portion 32 and the protrusion 34 of the handle 3 are not limited to those shown in the basic example and can be changed as appropriate. For example, the protrusion 34 may be separated from the base 1 when the rotation position of the handle 3 is the first rotation position.

[0101] The cabinet U1 may include a biasing member that applies a force to the handle 3 to hold the handle 3 in the first rotation position. The biasing member is, for example, a spring such as a torsion spring.
