[0009] (Embodiment) Below, a cabinet U1 and a distribution board U10 according to an embodiment will be described with reference to 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 rear, and the positive direction of the Z-axis direction as the up. 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, a cabinet U1 of this embodiment is a cabinet of a distribution board U10 and includes a base 1, a cover 2, and a slide member 3. The base 1 has a pair of first side walls 14 facing each other in a first direction D1, a connecting portion (a pair of side walls 15 and a bottom wall 13) connecting the pair of first side walls 14 to each other, and an opening 12 provided between the pair of first side walls 14. 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 bottom wall 23 has a through-hole 230 in an area adjacent to the second side walls 24. The slide member 3 has an attachment portion 6 disposed in a space SP1 (see FIG. 8 ) surrounded by the base 1 and the cover 2, and an operation portion 4 exposed to the outside of the space SP1 through a through-hole 230. The attachment portion 6 moves between a locked position (the position of the attachment portion 6 in FIG. 9 ) and an unlocked position (the position of the attachment portion 6 in FIGS. 10 and 11 ) in response to an operation of moving the operation portion 4 inside the through-hole 230 along a third direction D3. The third direction D3 is perpendicular to both the first direction D1 and the second direction D2. In the locked position, the attachment portion 6 attaches the second side wall 24 of the cover 2 to the first side wall 14 of the base 1. In the unlocked position, the attachment portion 6 allows the cover 2 to be removed from the base 1.

[0013] According to the above configuration, compared to when the operation unit 4 of the slide member 3 is provided on the side (right or left side) of the cabinet U1, it is possible to easily operate the operation unit 4 even if the cabinet U1 is installed in a narrow space. For example, it is possible to operate the operation unit 4 even if there is no working space on the right or left side of the cabinet U1. Therefore, it is possible to improve the workability of removing the cover 2 from the base 1 via the operation unit 4.

[0014] Furthermore, according to the above configuration, it is sufficient that at least the operating portion 4 of the sliding member 3 is exposed from the surface of the cover 2. Therefore, the area of ​​the sliding member 3 exposed from the surface of the cover 2 can be made relatively small. This allows the appearance of the cabinet U1 to be neat and tidy.

[0015] Specifically, the attachment of the base 1 and the cover 2 is performed as follows. With the attachment portion 6 held by the cover 2, as shown in FIG. 9, the attachment portion 6 is attached to the base 1 by a recessed / protruding engagement (the engagement of the recessed portion 65 with the protruding portion 16). As a result, the cover 2 is attached to the base 1 via the attachment portion 6. Furthermore, as shown in FIGS. 10 and 11, the recessed / protruding engagement is released, and the attachment portion 6 is removed from the base 1. As a result, the attachment of the cover 2 to the base 1 via the attachment portion 6 is released.

[0016] The cabinet U1 may include at least one slide member 3. In the illustrated example, the cabinet U1 includes two slide members 3.

[0017] The slide member 3 may have at least one attachment portion 6. In the illustrated example, the slide member 3 has two attachment portions 6. The two attachment portions 6 are connected to each other.

[0018] The distribution board U10 of this embodiment also includes a cabinet U1 and a wiring fixture 7. The wiring fixture 7 is disposed in a space SP1 surrounded by the base 1 and the cover 2. The wiring fixture 7 is, for example, a breaker.

[0019] The distribution board U10 may include at least one wiring fixture 7. In the example shown in FIG.

[0020] (detail) (1) Overall structure The overall configuration of the cabinet U1 will be described with reference to FIGS.

[0021] As described above, the cabinet U1 includes the base 1, the cover 2, and a pair (two) of slide members 3. The base 1 has a pair of first side walls 14. The cover 2 has a pair of second side walls 24.

[0022] Hereinafter, the pair of slide members 3 may be referred to as slide members 3A and 3B, respectively. Also, below, the pair of first side walls 14 may be referred to as first side walls 14A and 14B, respectively. Also, below, the pair of second side walls 24 may be referred to as second side walls 24A and 24B, respectively.

[0023] The first side wall 14A is provided on the right side of the base 1. The first side wall 14B is provided on the left side of the base 1.

[0024] The second side wall 24A is provided on the right side of the cover 2. The second side wall 24B is provided on the left side of the cover 2.

[0025] The slide member 3A is provided adjacent to the second side wall 24A. The second side wall 24A is attached to the first side wall 14A via the slide member 3A.

[0026] The slide member 3B is provided adjacent to the second side wall 24B. The second side wall 24B is attached to the first side wall 14B via the slide member 3B.

[0027] That is, the pair of slide members 3 respectively attach the pair of second side walls 24 of the cover 2 to the pair of first side walls 14 of the base 1. In other words, the slide member 3A attaches the second side wall 24A to the first side wall 14A, and the slide member 3B attaches the second side wall 24B to the first side wall 14B.

[0028] (2) Base The base 1 is a member made of, for example, resin or metal.

[0029] 2, the base 1 has openings 11 and 12, a bottom wall 13, a pair of first side walls 14, and a pair of side walls 15. Overall, the base 1 has a rectangular parallelepiped shape with opening 11 on the rear surface and opening 12 on the front surface. The base 1 is attached to a wall, for example, with the bottom wall 13 facing the wall of a building or the like.

[0030] The thickness direction of each of the pair of first side walls 14 is along the X-axis direction. The longitudinal direction of each of the pair of first side walls 14 is along the Z-axis direction. The pair of first side walls 14 face each other in the X-axis direction.

[0031] The thickness direction of each of the pair of side walls 15 is along the Z-axis direction. The longitudinal direction of each of the pair of side walls 15 is along the X-axis direction. The pair of side walls 15 face each other in the Z-axis direction.

[0032] One of the pair of side walls 15 connects the upper end portions of the pair of first side walls 14. The other of the pair of side walls 15 connects the lower end portions of the pair of first side walls 14.

[0033] The bottom wall 13 is shaped like a rectangular (rectangular or square) plate. The thickness direction of the bottom wall 13 is along the Y-axis direction. The bottom wall 13 covers the space surrounded by the pair of first side walls 14 and the pair of side walls 15 from the positive side (rear side) of the Y-axis. The pair of first side walls 14 and the pair of side walls 15 protrude from the outer edge of the bottom wall 13 toward the negative side of the Y-axis.

[0034] The opening 11 penetrates the bottom wall 13 in the Y-axis direction.

[0035] The opening 12 opens the space surrounded by the pair of first side walls 14 and the pair of side walls 15 to the negative side (front side) of the Y axis. In other words, the space is connected to the space in front of and outside the base 1 through the opening 12. The front ends of the pair of first side walls 14 and the pair of side walls 15 form the inner edge of the opening 12.

[0036] As shown in FIGS. 2, 8, 9, and 12, the base 1 further has a plurality of (four in this embodiment) protrusions 16. Two protrusions 16 protrude from the first side wall 14A. Two protrusions 16 protrude from the first side wall 14B. In each first side wall 14, the two protrusions 16 are arranged side by side with a gap in the Z-axis direction. Each protrusion 16 protrudes from the inner surface of the corresponding first side wall 14 in the thickness direction (X-axis direction) of the first side wall 14. Therefore, each protrusion 16 is disposed in the space between a pair of first side walls 14.

[0037] When viewed from the X-axis direction, the shape of the protrusion 16 is a trapezoid having an inclined surface 160 (see FIG. 12) on the positive side of the Z-axis. The protrusion 16 is inserted into the recess 65 provided in the corresponding mounting part 6, thereby mounting the cover 2 to the base 1.

[0038] (3) Cover The cover 2 is a member made of, for example, resin or metal.

[0039] 2, 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 an opening 22 on the rear surface.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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. The pair of second side walls 24 and the pair of side walls 25 protrude from the outer edge of the bottom wall 23 toward the positive side of the Y-axis.

[0044] The bottom wall 23 has two through holes 230. One of the two through holes 230 is provided in an area adjacent to the second side wall 24A. The other of the two through holes 230 is provided in an area adjacent to the second side wall 24B. The two through holes 230 are aligned in the X-axis direction. Each of the two through holes 230 is provided near the center of the bottom wall 23 in the Z-axis direction.

[0045] The opening 21 penetrates the bottom wall 23 in the Y-axis direction. The opening 21 is covered by a panel 26.

[0046] The panel 26 has openings 260, 261, and 262. The wiring device 7, meters, and the like fixed to the base 1 are arranged in the space SP1 inside the cabinet U1, and an operator can operate the wiring device 7 and view the meters through the openings 260, 261, and 262.

[0047] The panel 26 further has a door 263. The door 263 is made of a light-transmitting member that transmits light. The door 263 is movable between an open position (the position of the door 263 in FIGS. 1 and 2) where the opening 260 is open, and a closed position where the opening 260 is covered. More specifically, the door 263 is movable between the open position and the closed position by rotating about a hinge provided on the panel 26.

[0048] The opening 22 (see FIGS. 2 and 6) 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.

[0049] 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. Recesses 231 recessed toward the rear are provided on the left and right areas of the front surface of the bottom wall 23 on each side of the two handles 27, 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 two slide members 3, an operator can separate the cover 2 from the base 1 by grasping the two handles 27 and pulling the cover 2 forward.

[0050] As shown in Figures 6 to 9, the cover 2 further has a plurality of (four in this embodiment) first guide portions 28, a plurality of (four in this embodiment) second guide portions 29, and a plurality of (two in this embodiment) regulating portions 2a.

[0051] Two first guide portions 28, two second guide portions 29, and one restricting portion 2a protrude from the second side wall 24A. Two first guide portions 28, two second guide portions 29, and one restricting portion 2a protrude from the second side wall 24B.

[0052] The first guide part 28 is shaped like a rectangular parallelepiped, and has openings on its surface (rear surface) on the positive side of the Y axis and its surface (bottom surface) on the negative side of the Z axis. A part of the attachment part 6 of the sliding member 3 is inserted into the first guide part 28 through the opening of the first guide part 28, and the attachment part 6 slides along the first guide part 28 in the Z axis direction.

[0053] The second guide part 29 is box-shaped and has openings on its surface on the positive side of the Y axis (rear surface) and its surface on the positive side of the Z axis (top surface). A part of the attachment part 6 of the sliding member 3 is inserted into the second guide part 29 through the opening of the second guide part 29, and the attachment part 6 slides along the second guide part 29 in the Z axis direction.

[0054] The attachment portion 6 slides in the Z-axis direction along the first guide portion 28 and the second guide portion 29, thereby moving between the locked position and the unlocked position.

[0055] The first guide portion 28 and the second guide portion 29 function as a holder. The holder is a member that holds the mounting portion 6 when the mounting portion 6 is in the locked position and when the mounting portion 6 is in the unlocked position. Therefore, the holder prevents the slide member 3 from falling off the cover 2.

[0056] The holder holds the mounting portion 6 by restricting movement of the mounting portion 6 in the Y-axis direction (second direction D2). As shown in FIGS. 6 and 7, the holder (first guide portion 28 and second guide portion 29) is disposed in the gap in the Y-axis direction between the connection portion 5 of the sliding member 3 and the mounting portion 6. When the sliding member 3 attempts to move in the Y-axis direction, the sliding member 3 comes into contact with the holder, thereby preventing the sliding member 3 (and the mounting portion 6 of the sliding member 3, etc.) from moving in the Y-axis direction.

[0057] The restricting portion 2a is L-shaped. The restricting portion 2a is provided at a position where it fits into the sliding member 3 when the mounting portion 6 is in the unlocked position and the sliding member 3 moves in the Y-axis direction (second direction D2) relative to the cover 2. In other words, as the sliding member 3 moves, the restricting portion 2a is inserted into a recess 50 provided in the sliding member 3. This restricts the movement of the sliding member 3 toward the positive side of the Y-axis and along the Z-axis direction (third direction D3).

[0058] When the mounting portion 6 is in the unlocked position, the operator can press the operating portion 4 to insert the operating portion 4 through the through-hole 230 into the space SP1 surrounded by the base 1 and the cover 2. This causes the operating portion 4 to move together with the entire slide member 3 to the positive side of the Y axis, and the restricting portion 2a is inserted into the recess 50. The restricting portion 2a inserted into the recess 50 holds the slide member 3 and restricts movement of the slide member 3 (and the mounting portion 6 of the slide member 3, etc.) in the Z-axis direction (third direction D3).

[0059] (4) Slide member Each of the two slide members 3 is made of, for example, resin or metal.

[0060] The two slide members 3 are plane symmetrical with respect to a plane perpendicular to the X-axis. Therefore, the configuration of slide member 3A is the same as that of slide member 3B. The configuration of slide member 3A will be described below.

[0061] As shown in FIG. 3, the slide member 3 (3A) has an operating portion 4, a connecting portion 5, and two mounting portions 6.

[0062] The connecting portion 5 has a rectangular parallelepiped shape, and the longitudinal direction of the connecting portion 5 is along the Z-axis direction.

[0063] The connection part 5 has a recess 50. The recess 50 is provided on the surface (rear surface) of the connection part 5 on the positive side in the Y-axis direction. The connection part 5 is recessed forward at the recess 50. The recess 50 is provided near the center of the connection part 5 in the Z-axis direction.

[0064] The operating unit 4 protrudes from the connecting unit 5 on the negative side of the Y axis. The operating unit 4 is provided near the center of the connecting unit 5 in the Z axis direction. The operating unit 4 and the recess 50 are aligned in the Y axis direction. The operating unit 4 is fixed so as not to be able to move relative to the connecting unit 5. The surface of the operating unit 4 is provided with multiple grooves to prevent slipping (see Figure 13).

[0065] The two mounting portions 6 protrude from the connection portion 5 on the positive side of the Y axis. The two mounting portions 6 are arranged side by side with a gap in the Z axis direction. One of the two mounting portions 6 is provided above the operation portion 4, and the other of the two mounting portions 6 is provided below the operation portion 4. The two mounting portions 6 are fixed to the connection portion 5 so as not to be able to move relative to it.

[0066] The slide member 3 (3A) further has two first ribs 31 and two second ribs 32.

[0067] The two first ribs 31 correspond one-to-one to the two mounting portions 6. The two second ribs 32 correspond one-to-one to the two mounting portions 6. Each of the two first ribs 31 and the two second ribs 32 is provided near the corresponding mounting portion 6.

[0068] Two first ribs 31 and two second ribs 32 protrude from the connecting portion 5 toward the positive side of the Y axis. One first rib 31 and one second rib 32 corresponding to one mounting portion 6 are arranged side by side at intervals in the Z axis direction. The first ribs 31 are provided on the positive side of the Z axis relative to the corresponding mounting portion 6. The second ribs 32 face the corresponding mounting portion 6 in the Y axis direction.

[0069] As shown in FIGS. 4 and 5, the mounting portion 6 has a rail portion 61, a first protrusion 62, a second protrusion 63, and a third protrusion 64.

[0070] The rail portion 61 protrudes from the connection point between the mounting portion 6 and the connection portion 5 toward the positive side of the Z axis. When viewed in the Z axis direction, the rail portion 61 has a C-shape. The rail portion 61 has an opening 610 on the negative side of the Y axis. The first guide portion 28 of the cover 2 is inserted into the rail portion 61 through the opening 610 (see FIG. 6). An elastic member 8 is disposed in an internal space 611 of the rail portion 61.

[0071] The first protrusion 62 protrudes toward the negative side of the Z axis from the connection point between the attachment portion 6 and the connection portion 5. The first protrusion 62 is inserted into the second guide portion 29 of the cover 2 (see FIG. 6).

[0072] The second protrusion 63 is provided on the positive side of the Y axis relative to the first protrusion 62. The second protrusion 63 protrudes on the negative side of the Z axis. The second protrusion 63 has an inclined surface 630 on the negative side of the Z axis.

[0073] The first protrusion 62 and the second protrusion 63 form a recess 65. The recess 65 is a space surrounded by the first protrusion 62 and the second protrusion 63. When the mounting portion 6 is in the locked position, the protrusion 16 of the base 1 is inserted into the recess 65 (see FIG. 8). The shape of the recess 65 follows the shape of the protrusion 16.

[0074] A part of the inner surface of the recess 65 is an inclined surface 650. Therefore, when the protrusion 16 is inserted into the recess 65 and hits the inclined surface 650, the protrusion 16 moves along the inclined surface 650 toward the back of the recess 65. In this way, the inclined surface 650 functions as a guide that guides the protrusion 16 toward the back of the recess 65.

[0075] The third protrusion 64 protrudes from the second protrusion 63 toward the positive side of the Y axis. The third protrusion 64 has a notched cutout 640. The first side wall 14 of the base 1 is hooked onto the cutout 640 (see FIG. 8).

[0076] As shown in FIG. 7, the cabinet U1 further includes a plurality of (four; only one is shown in FIG. 7) elastic members 8. The elastic members 8 correspond one-to-one to the mounting portions 6. Each elastic member 8 applies an elastic force to the corresponding mounting portion 6.

[0077] The elastic member 8 is, for example, a compression spring. More specifically, the elastic member 8 is, for example, a compression coil spring. The elastic member 8 is disposed in the internal space 611 of the rail portion 61. A first end of the elastic member 8 contacts the first guide portion 28. A second end of the elastic member 8 contacts the bottom surface of the rail portion 61 in the internal space 611. When the mounting portion 6 moves from the locked position to the unlocked position, the elastic member 8 is sandwiched and compressed between the first guide portion 28 and the bottom surface of the rail portion 61 in the internal space 611.

[0078] The elastic member 8 applies a force to the mounting portion 6 that moves the mounting portion 6 from the unlocked position to the locked position. That is, when the mounting portion 6 moves from the locked position as shown in FIG. 6 to the unlocked position as shown in FIG. 7, the elastic member 8 is compressed and elastic energy is stored in the elastic member 8. When the mounting portion 6 is in the unlocked position, the elastic member 8 pushes the mounting portion 6 toward the locked position (i.e., toward the negative side of the Z axis). However, when the restricting portion 2a is inserted into the recess 50 of the sliding member 3 as shown in FIG. 15, the movement of the sliding member 3 in the Z axis direction is restricted, and the mounting portion 6 is held in the unlocked position.

[0079] (5) 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.

[0080] (5.1) How to attach two slide members to the cover First, the two slide members 3 are held by the cover 2. Specifically, as shown in FIG. 6 , the first guide portion 28 of the cover 2 is inserted into each of the rail portions 61 of the two mounting portions 6 of each slide member 3. Furthermore, the first protrusions 62 of each of the two mounting portions 6 of each slide member 3 are inserted into the second guide portion 29 of the cover 2. As a result, the mounting portions 6 are disposed between the first guide portion 28 and the second guide portion 29.

[0081] A pair of a first guide portion 28 and a second guide portion 29 is provided on each of the upper and lower sides of the second side wall 24A, and the two mounting portions 6 of the slide member 3A corresponding to the second side wall 24A are positioned between the corresponding first guide portion 28 and second guide portion 29, respectively.

[0082] Similarly, a pair of a first guide portion 28 and a second guide portion 29 is provided on each of the upper and lower sides of the second side wall 24B, and the two mounting portions 6 of the slide member 3B corresponding to the second side wall 24B are positioned between the corresponding first guide portion 28 and second guide portion 29, respectively.

[0083] The cover 2 may be provided with the two slide members 3 already held thereon.

[0084] The slide member 3 is guided by the first guide portion 28 and the second guide portion 29 at each of the two mounting portions 6, and is therefore capable of sliding in the Z-axis direction.

[0085] Furthermore, first guide portion 28 of cover 2 is disposed in the gap in the Y-axis direction between connection portion 5 and rail portion 61. Furthermore, second guide portion 29 is disposed in the gap in the Y-axis direction between connection portion 5 and first protrusion portion 62. Therefore, when slide member 3 attempts to move toward the positive side of the Y-axis, connection portion 5 abuts first guide portion 28 and second guide portion 29, thereby restricting movement of slide member 3 toward the positive side of the Y-axis. Furthermore, when slide member 3 attempts to move toward the negative side of the Y-axis, rail portion 61 abuts first guide portion 28 and first protrusion portion 62 abuts second guide portion 29, thereby restricting movement of slide member 3 toward the negative side of the Y-axis.

[0086] Note that there is a certain amount of gap in the Y-axis direction between the rail portion 61 and the first guide portion 28, and between the first protrusion 62 and the second guide portion 29. Therefore, the slide member 3 is able to move to a certain extent in the Y-axis direction relative to the cover 2. Specifically, the slide member 3 is able to move in the Y-axis direction between a position where the operation portion 4 is exposed on the surface of the cover 2 as shown in FIG. 14 and a position where the restriction portion 2a is inserted into the recess 50 as shown in FIG. 15.

[0087] (5.2) Attaching each mounting part to the base With the two slide members 3 held by the cover 2 as described above, the two mounting portions 6 provided on each of the two slide members 3 are attached to the base 1. In this way, the cover 2 is attached to the base 1 via the two slide members 3.

[0088] Specifically, first, when the operating portion 4 of the slide member 3 is not operated, as shown in FIG. 6, each mounting portion 6 is at the lower end (lock position) of the movable range.

[0089] The worker inserts the front end of the base 1 into the opening 22 (see FIG. 6) at the rear end of the cover 2. This brings the inclined surface 630 of the second protrusion 63 of each mounting portion 6 into contact with the inclined surface 160 of the protrusion 16 of the base 1, as shown in FIG.

[0090] The worker slides the operating unit 4 of each of the two slide members 3 toward the positive side of the Z axis, thereby sliding each slide member 3 toward the positive side of the Z axis, as shown in FIGS. 7 and 14. This moves each mounting unit 6 to the upper end of its movable range (unlocked position). The worker pushes the cover 2 toward the positive side of the Y axis while sliding the operating unit 4 toward the positive side of the Z axis. This causes the cover 2 and the two slide members 3 held by the cover 2 to move along the inclined surface 160. Therefore, as shown in FIG. 10, the cover 2 and the two slide members 3 held by the cover 2 move to a position where the recessed portion 65 of each mounting portion 6 faces the protruding portion 16 of the base 1.

[0091] Next, the worker releases the operating unit 4. Then, due to the elastic force of the elastic members 8, each mounting portion 6 moves to the lower end of its movable range (locked position), as shown in FIGS. 8 and 9. At this time, the protrusions 16 of the base 1 are inserted into the recesses 65 of each mounting portion 6. As a result, the cover 2 is attached to the base 1 via the two slide members 3. At this time, the engagement between the recesses 65 and the protrusions 16 restricts movement of the cover 2 in the Y-axis direction relative to the base 1.

[0092] Therefore, when the mounting portion 6 is in the locked position, the mounting portion 6 is attached to the first side wall 14 of the base 1. More specifically, the mounting portion 6 is attached to the first side wall 14 via the protrusion 16 protruding from the first side wall 14. Furthermore, as will be described later, when the mounting portion 6 moves from the locked position to the unlocked position, the mounting portion 6 is detached from the first side wall 14 of the base 1.

[0093] (5.3) Removing each mounting part from the base By removing the protrusions 16 of the base 1 from the recesses 65 of each mounting portion 6, the restriction on movement of the cover 2 in the Y-axis direction relative to the base 1 is released. With the restriction released, the worker moves the cover 2 toward the front (towards the negative side of the Y-axis), and the cover 2 is removed from the base 1.

[0094] Specifically, first, the worker slides the operating part 4 of one of the two slide members 3 toward the positive side of the Z axis, thereby sliding the slide member 3 toward the positive side of the Z axis, as shown in FIG. 10. This moves each mounting part 6 to the upper end of its movable range (unlocked position). This removes the protrusion 16 from the recess 65. In other words, the mounting part 6 is now in a state of being detached from the first side wall 14.

[0095] The worker further pushes the operating unit 4 toward the positive side of the Y axis (i.e., toward the back). This causes the slide member 3 to move toward the positive side of the Y axis. Then, as shown in FIG. 11, the restricting portion 2a of the cover 2 is inserted into the recess 50 of the slide member 3. This restricts the movement of the slide member 3 in the Z axis direction, and each mounting portion 6 is fixed in the unlocked position shown in FIG. 11. Even if the worker releases his or her hand from the operating unit 4, each mounting portion 6 remains in the unlocked position.

[0096] 11 and 15, the first rib 31 of the slide member 3 gets caught on the first guide portion 28 of the cover 2, and the second rib 32 of the slide member 3 gets caught on the second guide portion 29 of the cover 2. This restricts the slide member 3 from moving toward the negative side of the Z axis. The movement of the slide member 3 in the Z axis direction is restricted not only by the restricting portion 2a but also by the first rib 31 and the second rib 32, so that the slide member 3 is stably fixed.

[0097] As described above, after fixing the two mounting portions 6 of one of the two slide members 3 to the unlocked position, the worker also fixes the two mounting portions 6 of the other slide member 3 to the unlocked position using the same procedure.

[0098] Even if the worker releases his / her hands from the operating unit 4, the attachment parts 6 remain in the unlocked position, allowing the worker to perform other tasks using his / her hands. With the attachment parts 6 fixed in the unlocked position as shown in FIG. 11, the worker grasps the two handles 27 (see FIG. 1) of the cover 2 and tilts the cover 2 toward himself / herself. This causes the cover 2 to be removed from the base 1.

[0099] (5.4) Releasing the restriction on the movement of the slide member When the cover 2 is removed from the base 1, the attachment portions 6 of the two slide members 3 held by the cover 2 are fixed in the unlocked position. That is, as shown in FIG. 15, the restricting portions 2a of the cover 2 are inserted into the recesses 50 of the slide members 3. In other words, the attachment portions 6 (together with the entire slide member 3) are held by the restricting portions 2a. At this time, as shown in FIG. 15, the third protrusion 64 of the slide members 3 protrudes from the end of the cover 2 opposite the bottom wall 23 (the end on the positive side of the Y axis). That is, the third protrusion 64 protrudes outside the opening 22.

[0100] In this state, the worker presses the cover 2 against the plane F1, such as a floor, so that the end of the cover 2 on the positive side of the Y axis faces the plane F1. For example, the worker places the cover 2 on a horizontal plane F1, such as a floor, with the operating unit 4 facing up, and applies a downward load to the cover 2. Then, a reaction force is applied from the plane F1 to the slide member 3 via the third protrusion 64, and the slide member 3 moves toward the negative side of the Y axis relative to the cover 2. Therefore, as shown in FIG. 14 , the restricting portion 2a comes out of the recess 50. This releases the restricting portion 2a from holding the mounting portion 6. In other words, the restriction on the slide member 3's movement in the Z axis direction is released.

[0101] Then, due to the elastic force of the elastic member 8, each mounting portion 6 moves to the lock position as shown in FIG.

[0102] The worker may also apply a force directly to the third protrusion 64 to remove the restricting portion 2a from the recess 50.

[0103] (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 embodiment described above will be referred to as a basic example.

[0104] The slide member 3 may have one attachment portion 6. Alternatively, the slide member 3 may have three or more attachment portions 6 connected to each other.

[0105] The cabinet U1 may include one slide member 3. Alternatively, the cabinet U1 may include three or more slide members 3.

[0106] As the elastic member 8 for applying a force to the mounting portion 6 to move the mounting portion 6 to the locked position, a tension spring may be used instead of a compression spring.

[0107] The slide member 3 may not have the connection portion 5 , and the operation portion 4 may protrude from the surface of the attachment portion 6 .

[0108] In the basic example, the recess 50 is provided in the connecting portion 5 of the slide member 3. However, the position where the recess 50 is provided is not particularly limited, and the recess 50 may be provided in the attachment portion 6, for example.

[0109] The restricting portion 2a in the basic example is a protrusion that is inserted into the recess 50 of the slide member 3. Alternatively, the restricting portion 2a may be a recess into which the protrusion of the slide member 3 is inserted. Similarly, in the basic example, the recess and the protrusion of the coupling structure that is connected by fitting the recess and the protrusion may be interchanged. Furthermore, instead of the recess and the 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.

[0110] In the basic example, two guide portions (first guide portion 28 and second guide portion 29) for guiding movement of the mounting portion 6 in the Z-axis direction are provided on the cover 2. However, the number of guide portions may be one or three or more.

[0111] In the basic example, the guide portions (first guide portion 28 and second guide portion 29) for guiding the movement of the mounting portion 6 in the Z-axis direction also serve as the holder. The holder holds the mounting portion 6 when the mounting portion 6 is in the locked position and when the mounting portion 6 is in the unlocked position. However, the holder may be provided separately from the guide portions.

[0112] (summary) The above-described embodiments and the like disclose the following aspects.

[0113] The cabinet (U1) according to the first aspect is a cabinet for a distribution board (U10) and includes a base (1), a cover (2), and a slide member (3). The base (1) has a pair of first side walls (14) facing each other in a first direction (D1), a connecting portion (a pair of side walls (15) and a bottom wall (13)) connecting the pair of first side walls (14), and an opening (12) provided between the pair of first side walls (14). 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). The bottom wall (23) covers the opening (12) of the base (1) in a second direction (D2) perpendicular to the first direction (D1). The bottom wall (23) has a through-hole (230) in an area adjacent to the second side wall (24). The slide member (3) has an attachment portion (6) disposed in a space (SP1) surrounded by the base (1) and the cover (2), and an operating portion (4) exposed to the outside of the space (SP1) through the through-hole (230). The attachment portion (6) moves between a locked position and an unlocked position in response to an operation of moving the operating portion (4) inside the through-hole (230) along a third direction (D3). The third direction (D3) is perpendicular to both the first direction (D1) and the second direction (D2). In the locked position, the attachment portion (6) attaches the second side wall (24) of the cover (2) to the first side wall (14) of the base (1). In the unlocked position, the attachment portion (6) allows the cover (2) to be removed from the base (1).

[0114] According to the above configuration, compared to when the operating unit (4) of the sliding member (3) is provided on the side of the cabinet (U1), the operating unit (4) can be easily operated even when the cabinet (U1) is installed in a narrow space. Therefore, the workability of removing the cover (2) from the base (1) via the operating unit (4) can be improved. Furthermore, according to the above configuration, the area of ​​the sliding member (3) exposed from the surface of the cover (2) can be relatively small. This allows the cabinet (U1) to have a neater appearance.

[0115] In the cabinet (U1) according to the second aspect, the cover (2) in the first aspect further includes a holder (first guide portion (28) and second guide portion (29)). The holder holds the mounting portion (6) when the mounting portion (6) is in the locked position and when the mounting portion (6) is in the unlocked position.

[0116] According to the above configuration, the slide member 3 can be maintained attached to the cover 2. Therefore, an operator can easily attach the cover 2 to the base 1 via the attachment portion 6 of the slide member 3 without having to perform complicated tasks such as holding the slide member 3.

[0117] In the cabinet (U1) according to the third aspect, in the second aspect, the holder restricts movement of the attachment portion (6) in the second direction (D2).

[0118] The above configuration can prevent the slide member 3 from shifting position, allowing the worker to easily attach the cover 2 to the base 1 via the attachment portion 6 of the slide member 3.

[0119] In addition, in the cabinet (U1) according to a fourth aspect, in any one of the first to third aspects, when the mounting portion (6) is in the locked position, the mounting portion (6) is attached to the first side wall (14) of the base (1). When the mounting portion (6) moves from the locked position to the unlocked position, the mounting portion (6) is detached from the first side wall (14) of the base (1).

[0120] According to the above configuration, the length of the mounting portion (6) in the second direction (D2) can be made shorter than when the mounting portion (6) is attached to the bottom wall (13) of the base (1).

[0121] In addition, in the cabinet (U1) according to a fifth aspect, in any one of the first to fourth aspects, the cover (2) further has guide portions (a first guide portion (28) and a second guide portion (29)). The attachment portion (6) moves along the guide portions between a locked position and an unlocked position.

[0122] According to the above configuration, the mounting portion (6) can be easily moved between the locked position and the unlocked position.

[0123] In addition, in the cabinet (U1) according to a sixth aspect, in any one of the first to fifth aspects, the cover (2) further includes a restricting portion (2a). The restricting portion (2a) holds the sliding member (3) when the operating portion (4) is inserted into the space (SP1) surrounded by the base (1) and the cover (2) through the through-hole (230), and restricts movement of the mounting portion (6) in the third direction (D3).

[0124] According to the above configuration, the restricting portion 2a can be used to hold the mounting portion 6 in the unlocked position. Therefore, even if the operator does not press the operating portion 4 to hold the mounting portion 6 in the unlocked position, the operator can remove the cover 2 from the base 1. In other words, the workability of removing the cover 2 from the base 1 can be further improved.

[0125] In addition, in the cabinet (U1) according to the seventh aspect, in the sixth aspect, the regulating portion (2a) is provided in a position where it engages with the slide member (3) when the slide member (3) moves in the second direction (D2) relative to the cover (2) when the mounting portion (6) is in the unlocked position.

[0126] According to the above configuration, the worker can easily perform the operation of holding the slide member (3) on the restricting portion (2a).

[0127] In addition, in the cabinet (U1) according to the eighth aspect, when the mounting portion (6) is held by the restricting portion (2a) in the seventh aspect, the slide member (3) protrudes from the end of the cover (2) opposite the bottom wall (23).

[0128] According to the above configuration, by pressing the end of the cover (2) against a flat surface (for example, a floor), the restricting portion (2a) can be released from holding the mounting portion (6). In this way, with a simple operation, the restricting portion (2a) can be released from holding the mounting portion (6).

[0129] In addition, in the cabinet (U1) according to a ninth aspect, in any one of the first to eighth aspects, the cover (2) has a handle (27) that is provided on the bottom wall (23) and can be gripped by an operator from the outside.

[0130] According to the above configuration, even if the space on the side of the cabinet (U1) is narrow, the worker can remove the cover (2) from the base (1) by gripping the handle (27).

[0131] Furthermore, the cabinet (U1) according to a tenth aspect is any one of the first to ninth aspects, and further includes an elastic member (8). The elastic member (8) applies a force to the mounting portion (6) that moves the mounting portion (6) from the unlocked position to the locked position.

[0132] According to the above configuration, the mounting portion (6) can be stably maintained in the locked position.

[0133] In addition, in a cabinet (U1) according to an eleventh aspect, in any one of the first to tenth aspects, the base (1) has a protrusion (16) protruding from the first side wall (14). The mounting portion (6) has a recess (65) into which the protrusion (16) is inserted when the mounting portion (6) is in the locked position.

[0134] According to the above configuration, the cover (2) can be attached to the base (1) with a simple structure.

[0135] In addition, in the cabinet (U1) according to a twelfth aspect, in any one of the first to eleventh aspects, the slide member (3) has a plurality of mounting portions (6) including the above-mentioned mounting portion (6). The plurality of mounting portions (6) are connected to each other.

[0136] According to the above configuration, the cover (2) can be attached to the base (1) more stably than when the slide member (3) has only one attachment portion (6).

[0137] Furthermore, the cabinet (U1) according to a thirteenth aspect is any one of the first to twelfth aspects and includes a pair of slide members (3) including the slide member (3). The pair of slide members (3) respectively attach a pair of second side walls (24) of the cover (2) to a pair of first side walls (14) of the base (1).

[0138] According to the above configuration, the cover (2) can be attached to the base (1) more stably than when the cabinet (U1) has only one slide member (3).

[0139] The configurations other than the first aspect are not essential for the cabinet (U1) and can be omitted as appropriate.

[0140] A distribution board (U10) according to a fourteenth aspect includes the cabinet (U1) according to any one of the first to thirteenth aspects and a wiring device (7). The wiring device (7) is disposed in a space (SP1) surrounded by the base (1) and the cover (2).

[0141] According to the above configuration, it is possible to provide a distribution board (U10) that improves the workability of removing the cover (2) from the base (1) of the cabinet (U1). [Explanation of symbols]
