Description

[Technical Field]

[0001] The present invention relates to a support unit, a mounting plate unit, and a box for accommodating electrical and electronic equipment. [Background Art]

[0002] A device mounting plate for mounting electrical and electronic equipment to be stored in the box body of a box for accommodating electrical and electronic equipment is normally mounted on the back side of the box body. However, the fact that the device mounting plate can only be arranged at such a position may not be suitable for efficient utilization of the internal space of the box body. On the other hand, as described in Patent Document 1 and Patent Document 2, structures are known that allow the device mounting plate to be arranged at a position other than the back surface of the box body. The structure disclosed in Patent Document 1 is a structure in which comb-shaped holders are attached to slots formed in the box body, and the structure disclosed in Patent Document 2 is a structure in which corner members are attached to guide rails formed in the box body.

[0004] Incidentally, both the structure disclosed in Patent Document 1 and the structure disclosed in Patent Document 2 require processing on the box body. However, it is preferable that the amount of processing on the box body be kept as small as possible. [Summary of the Invention] [Problem to be Solved by the Invention]

Mode for Carrying Out the Invention

[0015] The following describes embodiments for carrying out the invention. The support unit 30 of the embodiment is used to support an equipment mounting plate 51 on which electrical and electronic equipment housed in the box body 11 of the electrical and electronic equipment storage box 10 can be attached. This support unit 30 is equipped with a movable member that can be moved in the direction of the inner surface of the box body 11, and by moving the movable member, the contact portion can be brought into contact with the inner surface of the box body 11. For this reason, the equipment mounting plate 51 for attaching electrical and electronic equipment can be supported without any special processing of the box body 11 of the electrical and electronic equipment storage box 10.

[0016] Furthermore, in the embodiment, the mounting plate unit 50 has a support unit 30 attached to the equipment mounting plate 51 that supports the equipment mounting plate 51 to which electrical and electronic equipment housed in the box body 11 of the electrical and electronic equipment storage box 10 can be mounted. In addition, the support unit 30 provided in this mounting plate unit 50 is equipped with a movable member that can be moved toward the inner surface of the box body 11, and by moving the movable member, the contact portion can be brought into contact with the inner surface of the box body 11. For this reason, the equipment mounting plate 51 for mounting electrical and electronic equipment can be supported without any special processing of the box body 11 of the electrical and electronic equipment storage box 10.

[0017] Furthermore, the electrical and electronic equipment storage box 10 of the embodiment includes a box body 11 capable of housing electrical and electronic equipment mounted on an equipment mounting plate 51, and a door 12 capable of covering an opening 13 provided in the box body 11. This electrical and electronic equipment storage box 10 is equipped with a support unit 30 capable of supporting the equipment mounting plate 51 on the box body 11, and the support unit 30 is equipped with a movable member that can be moved in the direction of the inner surface of the box body 11, and by moving the movable member, it is possible to switch between a state in which the contact portion is in contact with the inner surface of the box body 11 and a state in which it is not in contact. For this reason, the equipment mounting plate 51 for mounting electrical and electronic equipment can be supported without any special processing of the box body 11 of the electrical and electronic equipment storage box 10.

[0018] As can be seen from Figure 1, the support unit 30 of the embodiment is arranged inside the electrical and electronic equipment storage box 10. The electrical and electronic equipment storage box 10 comprises a box body 11 for housing electrical and electronic equipment and a door 12 capable of covering an opening 13 provided in the box body 11. The electrical and electronic equipment storage box 10 may be made of metal or resin.

[0019] In this embodiment, the door 12 that covers the box body 11 is connected to the box body 11 using a hinge 14 so that it can rotate relative to the box body 11 (see Figures 1 and 2), but the box body 11 and the door 12 do not necessarily have to be connected by a hinge 14. The electrical and electronic equipment storage box 10 is also equipped with a handle 15 used for opening and closing the door 12 and for locking the door 12 to the box body 11. Furthermore, a gasket 16 is provided on the back of the door 12 to prevent water, dust, etc. from entering the box body 11 when the door 12 is closed (see Figure 1).

[0020] The box body 11 houses an equipment mounting plate 51 used for mounting electrical and electronic equipment (not shown), such as circuit breakers (see Figures 3 to 6). While electrical and electronic equipment can include circuit breakers, switches, terminal blocks, relays, communication equipment, sensors, thermal equipment, and lighting equipment, it is not limited to these; any equipment that applies electrical or electronic engineering principles may be used.

[0021] The support unit 30, which is positioned inside the electrical and electronic equipment storage box 10, is used to support the equipment mounting plate 51 and can be brought into contact with the inner surface of the box body 11. The support unit 30 comprises a mounting member 32 that can be used to place the equipment mounting plate 51 on, and a support member 33 that can come into contact with the inner surface of the box body 11. The support member 33 functions as a movable member that moves within the box body 11 to bring its contact portion into contact with the inner surface of the box body 11 (see Figures 5 to 8).

[0022] The mounting member 32 in the example shown in Figures 9 to 11 is provided with an elongated hole 321 into which a bolt 34 can be inserted. The mounting member 32 is movable while being constrained by the bolt 34 inserted into the elongated hole 321 and the elongated hole 321. Furthermore, the bolt 34 and nut 35 can be fastened so that the mounting member 32 and the equipment mounting plate 51 are sandwiched between the head of the bolt 34 and the nut 35. In order for the contact portion of the support unit 30 to properly contact the inner surface of the box body 11, it is preferable to configure the mounting member 32 so that the elongated hole 321 extends from the corner side of the equipment mounting plate 51 toward the corner side of the box body 11.

[0023] The support unit 30 and the equipment mounting plate 51 can be fixed together, for example, by placing the equipment mounting plate 51 on the mounting member 32 and then fastening the bolt 34 to the nut 35. Of course, in this case, they are fixed together so that they cannot move by firmly fastening the bolt 34 to the nut 35.

[0024] Furthermore, in the examples shown in Figures 9 to 11, the end of the mounting member 32 opposite to the side fixed to the equipment mounting plate 51 is connected to a support member 33 by fasteners 37, with a connecting member 36 attached to it. The connecting member 36 may be fixed to the support member 33 by welding or fasteners 37 so that the equipment mounting plate 51 is supported at a predetermined position on the support member 33, or a structure in which the connecting member 36 and the support member 33 engage may be adopted so that the position in which the support member 33 supports the equipment mounting plate 51 can be changed.

[0025] Furthermore, by fixing multiple connecting members 36 along the longitudinal direction (front-to-back direction) of the support member 33, the support member 33 may be configured to support multiple equipment mounting plates 51. In this way, it is possible to attach multiple equipment mounting plates 51 to the support unit 30 (see Figure 12). In the example shown in Figure 12, two equipment mounting plates 51 are attached to the support unit 30, but three or more equipment mounting plates 51 may be attached. Also, if there are multiple connecting members 36 to which the equipment mounting plates 51 are attached, it is not necessary to attach equipment mounting plates 51 to all of them. Equipment mounting plates 51 may be attached only to selected connecting members 36.

[0026] In the examples shown in Figures 9 to 11, by loosening the bolts 34 and nuts 35 connecting the equipment mounting plate 51 and the mounting member 32 while maintaining the fixed state of the support member 33 and the connecting member 36, and the connecting member 36 and the mounting member 32, it is possible to change the positional relationship between the support unit 30 and the equipment mounting plate 51 while maintaining the state in which the support unit 30 is connected to the equipment mounting plate 51. Of course, by tightening the bolts 34 and nuts 35 securely after changing their positional relationship, it is possible to fix that positional relationship.

[0027] As can be understood from this description, in the examples shown in Figures 5 to 11, the support unit 30 can be switched between a movable state and an immovable state relative to the equipment mounting plate 51. Therefore, by moving the support unit 30 inside the box body 11, the support unit 30 can be firmly brought into contact with the inner surface of the box body 11, and then the support unit 30 can be made immovable. In this way, the mounting plate unit 50 can increase the contact surface with the box body 11, and the position of the mounting plate unit 50 inside the box body 11 can be determined.

[0028] In the examples shown in Figures 5 to 11, the mounting plate unit 50 is provided with support units 30 at all four corners of the equipment mounting plate 51, so that it can be firmly in contact with the inner surface of the box body 11 located in the vertical, horizontal, and vertical directions.

[0029] As can be understood from these descriptions, it is preferable that the support unit 30 attached to the equipment mounting plate 51 be configured to be in contact with the corner portion inside the box body 11. Furthermore, it is preferable that a separate support unit 30 be configured to be in contact with each of the four corner portions inside the box body 11.

[0030] The equipment mounting plate unit 50 can provide a certain level of support whether it is positioned to span the top and bottom surfaces of the box body 11 or to span both sides, but it is preferable to position it to span the top and bottom surfaces of the box body 11 and also span both sides.

[0031] This can be done by positioning support units 30 at each of the four corners of the box body 11, or by connecting separate support units 30 to each of the four sides of the equipment mounting plate 51, so that the support unit 30 connected to the top side and the support unit 30 connected to the bottom side of the equipment mounting plate 51 contact the box body 11 at locations other than the four corners, or by connecting the support unit 30 connected to the right side and the support unit 30 connected to the left side of the equipment mounting plate 51 contact the box body 11 at locations other than the four corners (see Figure 13).

[0032] Furthermore, it is preferable that at least one of the contact portions of the support unit 30 contacts two or more inner surfaces that form the corner portion of the box body 11, but it is preferable that any two to four or more support units 30 contact two or more inner surfaces that form the corner portion of the box body 11.

[0033] Here, we will explain an example of the installation procedure in the example shown in Figures 1 to 6. First, the support unit 30 is attached to the equipment mounting plate 51 to form a mounting plate unit 50, and this mounting plate unit 50 is then placed inside the electrical and electronic equipment storage box 10 (see Figures 3 to 5). In this example, the rear surface of the support member 33 is in contact with the inner surface on the rear side of the box body 11, but the other surfaces of the support member 33 are not in contact with the inner surface of the box body 11.

[0034] Next, the movable member of the support member 33 is moved in a direction perpendicular to the front-rear direction (up, down, right, left, etc.) toward the corner of the box body 11 (see Figures 5 to 8). At this time, one of the top, bottom, left, or right surfaces of the support member 33 is brought into contact with the inner surface of the box body 11 (one of the top, bottom, left, or right surfaces). After that, the bolt 34 and nut 35 fitted into the elongated hole 321 of the mounting member 32 are firmly fastened to suppress the movement of the support member 33 (see Figures 9 to 11). By following these steps, one of the top, bottom, left, or right surfaces of each of the four support units 30 is kept in contact with the inner surface of the box body 11 (one of the top, bottom, left, or right surfaces), thereby suppressing the movement of the mounting plate unit 50 in the up, down, left, and right directions within the box body 11.

[0035] Furthermore, for convenience in attaching and detaching the support unit 30, the electrical and electronic equipment storage box 10 is designed such that the door 12 can cover the opening 13 provided on the front side of the box body 11, and the support unit 30, which can abut against the corner portion inside the box body 11, can move its movable member in a direction perpendicular to the front-rear direction, and it is preferable that at least one support unit 30 is configured to abut against two or more inner surfaces that form the corner portion of the box body 11. The movable member may move linearly in a direction perpendicular to the front-rear direction, or it may rotate.

[0036] If it is desired to suppress the movement of the mounting plate unit 50 in the front-to-back direction, an elastic material such as rubber, sponge, or spring may be attached to the front of the support unit 30, and these materials may be brought into contact with the inner front surface of the box body 11 when the support unit 30 moves. Alternatively, after the support unit 30 is in contact with the inner surfaces (top, bottom, left, and right) of the box body 11, an elastic material may be inserted between the front of the support unit 30 and the inner surface of the box body 11 on the door 12 side to suppress the movement of the mounting plate unit 50 in the front-to-back direction.

[0037] Next, we will describe the example shown in Figures 14 to 22. In this example, the support member 33 has a shape in which the short end of a plate material is bent at an acute angle, and has a horizontally elongated opening 41 for attaching the mounting member 32 and a substantially L-shaped opening 42 for attaching the movable member (see Figures 15 and 16). The mounting member 32 inserted into the horizontally elongated opening 41 abuts against the support member 33 on both the front and back surfaces and is held by the support member 33. As can be seen from Figure 17, the connecting member 43 inserted into the substantially L-shaped opening 42 can be moved by operating the operating part 431 that protrudes from the support member 33. The connecting member 43 has a contact portion that can abut against the inner surface of the door 12 side of the box body 11. In other words, this connecting member 43 functions as both a movable member and a contact portion.

[0038] Here, we will explain the procedure for attaching the support unit 30 and the equipment mounting plate 51 to the box body 11 in the example shown in Figure 14. First, the support member 33, which holds the mounting member 32 and the connecting member 43, is installed at the corner of the box body 11 (see Figures 18 and 19). At this time, the rear surface of the support member 33 is in contact with the inner surface (rear surface) of the box body 11, and the bent surface of the support member 33 is in contact with the inner surfaces (any two of the top, bottom, left, or right) of the box body 11.

[0039] Next, by operating the operating part 431 of the connecting member 43 of the support member 33 in the forward direction, the connecting member 43 is moved in the forward direction, and the contact portion comes into contact with the inner surface of the box body 11 on the door 12 side. Note that the connecting member 43 in this embodiment has an elastic part (not shown), and when the movement in the forward direction is stopped, it returns to its original position. For this reason, by rotating the operating part 431 in a direction perpendicular to the forward direction (any direction up, down, left, or right) while the contact portion is in contact with the inner surface of the box body 11 on the door 12 side, the operating part 431 is locked into the L-shaped opening 42 of the support member 33, thereby preventing the connecting member 43 from returning to its original position. In this way, by preventing the positional relationship between the support member 33 and the connecting member 43 from shifting, the state in which the contact portion comes into contact with the inner surface of the box body 11 on the door 12 side can be maintained.

[0040] In this way, the support units 30 are placed in the necessary locations on the box body 11 (usually the four corners), the equipment mounting plate 51 is placed on the mounting member 32, and the equipment mounting plate 51 is fastened to the mounting member 32 using bolts 34 or the like (see Figures 20 and 21).

[0041] For convenience in attaching and detaching the support unit 30, the door 12 of the electrical and electronic equipment storage box 10 can cover the opening 13 provided on the front side of the box body 11, and the support unit 30 that can abut against the corner portion inside the box body 11 can move its movable member in the front-rear direction, and it is preferable that at least one support unit 30 abuts against the inner surface of the box body 11 on the door 12 side.

[0042] Furthermore, even if the support unit 30 is configured such that the movable member can move in the front-rear direction, and at least one of the contact parts of the support unit 30 contacts the inner surface of the box body 11 on the door 12 side, the support unit 30 does not need to be connected to the corner of the equipment mounting plate 51. For example, as can be seen from Figure 22, it may be configured to be connected to the central part of the right end (and / or left end) of the equipment mounting plate 51 or to the central part of the upper end (and / or lower end) of the equipment mounting plate 51.

[0043] Furthermore, the support member 33 may be provided with multiple openings used to hold the mounting member 32. With this configuration, it is possible to support multiple equipment mounting plates 51 with respect to the support member 33, or to change the installation position of the equipment mounting plates 51.

[0044] Furthermore, the support unit 30 may be configured to combine the examples shown in Figures 9 to 11 and the example shown in Figure 17. For example, a connecting member 43, as shown in the example in Figure 17, may be provided to the support member 33 in the example shown in Figures 9 to 11. In this case, after fixing the support unit 30 and the equipment mounting plate 51 to the box body 11 as described in the procedure for the example shown in Figures 9 to 11, the connecting member 43 can be moved as described in the procedure for the example in Figure 17 and brought into contact with the inner surface of the door 12 side of the box body 11.

[0045] Incidentally, considering the convenience of installation and removal work in the electrical and electronic equipment storage box 10, it is preferable that the mounting plate unit 50 can be inserted into and removed from the box body 11 of the electrical and electronic equipment storage box 10 while still attached to the equipment mounting plate 51. For this reason, it is preferable that the electrical and electronic equipment storage box 10 is equipped with a mounting plate unit 50 in which a support unit 30 is attached to an equipment mounting plate 51, and that the mounting plate unit 50 can be shortened in length in the vertical and / or horizontal directions by moving the support unit 30, so that the support unit 30 can be removed from the opening 13 provided on the front side of the electrical and electronic equipment storage box 10 while still attached to the equipment mounting plate 51.

[0046] Such a configuration is particularly preferable when the height of the opening 13 is shorter than the height of the box body 11 for housing electrical and electronic equipment, or when the height of the opening 13 is shorter than the width of the box body 11 for housing electrical and electronic equipment. However, even if these conditions are not met, it is still possible to improve convenience during operation.

[0047] In the examples shown in Figures 3 to 6, the electrical and electronic equipment storage box 10 is such that the vertical length of the opening 13 is shorter than the vertical length of the box body 11, and the horizontal length of the opening 13 is shorter than the horizontal length of the box body 11. The mounting plate unit 50 is stored in the box body 11 with the support unit 30 and the equipment mounting plate 51 connected, and then the support unit 30 is moved so that it expands within the box body 11. To remove it, the reverse is done, with the support unit 30 being moved to contract the mounting plate unit 50, and then the mounting plate unit 50 is removed with the support unit 30 and the equipment mounting plate 51 connected.

[0048] Furthermore, the electrical and electronic equipment storage box 10 shown in Figure 3 and other figures is equipped with an equipment mounting plate 51 to which the support unit 30 is attached, as well as an equipment mounting plate 19 fixed to the rear surface of the box body. The equipment mounting plate 19 is fixed to the rear surface of the box body 11, as is conventional, and the equipment mounting plate 51 is an equipment mounting plate 51 supported by the support unit 30 described above.

[0049] In this way, by providing an equipment mounting plate 19 fixed to the rear surface of the box body 11 with screws or the like, and by using a support unit 30 to further arrange equipment mounting plates 51 inside the box body 11, it becomes possible to increase the number of places where electrical and electronic equipment can be fixed inside the box body 11, thereby increasing the variations in how electrical and electronic equipment can be stored inside the box body 11. Furthermore, an increase in the amount of electrical and electronic equipment that can be stored in the box body 11 can be expected. Of course, it is also possible to have an electrical and electronic equipment storage box 10 in which all of the equipment mounting plates stored inside the box body 11 are equipment mounting plates 51 supported by the support unit 30.

[0050] Furthermore, if the support unit 30 is configured to be detachable from the equipment mounting plate 51, it becomes easier to install the equipment mounting plate 51 even if wired electrical and electronic equipment is fixed inside the box body 11.

[0051] For example, when using a support unit 30 with the configuration shown in Figures 14 to 22, the support unit 30 can be placed on the necessary locations on the box body 11, with the wiring already connected to each electrical and electronic device fixed to the equipment mounting plate 19, and then the equipment mounting plate 51 can be placed on the mounting member 32. By adopting this configuration in which the equipment mounting plate 51 is fixed to the mounting member 32 with the wiring visible, the equipment mounting plate 51 can be attached while suppressing problems such as pinching the wiring, even if wiring already exists inside the box body 1.
