DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] An embodiment of the invention will be described below. As can be understood from Fig. 1 to Fig. 4, a cabinet 1 for storing electric and electronic equipment according to this embodiment includes a back plate portion 11, a side plate portion 12 rising from the back plate portion 11, and a front opening portion 13. This cabinet 1 for storing electric and electronic equipment includes a back rail 50 having a mounting surface 52 having a plurality of mounting holes 51 in the longitudinal direction to which a wiring restraint for restraining wiring can be attached, and the back rail 50 is disposed along the back plate portion 11 such that the mounting surface 52 is inclined toward the front opening portion 13. This makes it possible to provide a cabinet 1 for storing electric and electronic equipment that is easy to perform wiring work.

[0015] Here, the cabinet 1 for storing electric and electronic equipment according to the embodiment will be described. The cabinet 1 for storing electric and electronic equipment according to the embodiment includes a housing body 10 having a front opening 13, and a door 21 connected to the housing body 10 by a door hinge part 20. The housing body 10 and the door 21 form the outer shape of the cabinet 1 for storing electric and electronic equipment. The housing body 10 also includes a back plate part 11 located on the rear side, a side plate part 12 rising from the back plate part 11, and a front opening 13. The front opening 13 is located on the front side of the housing body 10 and spreads over almost the entire surface. In the example shown in FIG. 1, a rotatable protective plate 22 is provided inside the housing body 10. The protective plate 22 ensures the safety of the operator even when the door 21 is opened.

[0016] Incidentally, the electrical / electronic equipment storage cabinet 1 of the embodiment has a rear rail 50 disposed along the rear plate portion 11. This rear rail 50 has a plurality of mounting holes 51 for mounting wiring restraints that restrain wiring, and more specifically, has a mounting surface 52 on which a plurality of mounting holes 51 are arranged along the longitudinal direction of the rear rail 50. This rear rail 50 is fixed to the housing body 10 such that the mounting surface 52 is inclined toward the front opening 13.

[0017] In the embodiment, the rear rail 50 is disposed so as to extend in the vertical direction near the right corner and the left corner of the rear side of the housing body 10, but this is not necessary to be limited to such a form. For example, the rear rail 50 may be disposed only on the right side or the left side. Also, multiple rear rails 50 may be disposed so as to be aligned in the vertical direction.

[0018] In the embodiment, a rail mounting member 31 is used to fix the rear rail 50 to the housing body 10. In the example shown in Fig. 5 to Fig. 8, the rail mounting member 31 is attached to the rear plate 11 and the side plate 12 of the housing body 10. If the rail mounting member 31 is attached so as to straddle the rear plate 11 and the side plate 12, the force supporting the rear rail 50 can be increased. Note that when attaching the rail mounting member 31, various means such as welding or screwing can be used.

[0019] As can be seen from Fig. 8, the rail mounting member 31 of the embodiment is configured so that the support surface 32 that supports the rear rail 50 is inclined toward the front opening 13. The rear rail 50 can be attached to the support surface 32 of this rail mounting member 31 so that it faces the support surface 32. Note that the support surface 32 of the embodiment is provided with a fastening hole into which a male screw can be inserted. The fastening hole of the embodiment is provided with a female thread portion, so that it can be screwed into a male screw.

[0020] In this way, by attaching the rear rail 50 to the housing body 10 via the rail mounting member 31, it is not necessary to give the rear rail 50 a complex shape, and it can be arranged at an angle toward the front opening 13. As can be seen from Fig. 4, the rear rail 50 in the embodiment has a substantially U-shaped cross section.

[0021] In the form of the rail mounting member 31 shown in Figures 5 to 8, the support surface 32, the surface 33 attached to the back plate portion 11, and the surface 34 attached to the side plate portion 12 extend relative to the approximately pentagonal connecting portion 35 so as to form an angle of approximately 90 degrees with the connecting portion 35, but this configuration is not necessary and various forms are possible.

[0022] As can be seen from this example, in order to avoid making the rear rail 50 into a complicated shape, it is preferable to configure the rear plate 11 or the side plate 12 to include a rail mounting member 31, and to configure the support surface 32 of the rail mounting member 31 that supports the rear rail 50 to be inclined toward the front opening 13. However, the rear rail 50 may be directly fixed to the housing body 10 without using the rail mounting member 31. In this case, the rear rail 50 may also be configured in various forms. For example, the rear rail 50 of the example shown in FIG. 9 is configured by bending a plate-shaped member so that the cross section is approximately triangular. In addition, in another example of the rear rail 50 shown in FIG. 10, the surface attached to the rear plate 11 and the surface attached to the side plate 12 are configured to be located outside the mounting surface 52.

[0023] In these examples, the rail mounting member 31 and the rear rail 50 are fixed to both the rear plate 11 and the side plate 12, but they may be fixed to either one. Also, the rear rail 50 may be arranged in a row in the vertical direction.

[0024] Incidentally, the mounting holes 51 of the rear rail 50 in the embodiment are square and circular holes that are arranged in a row with a gap between them. By arranging holes of a plurality of shapes in a row in this way, it is possible to expand the range of options for items that can be attached to the rear rail 50. Of course, the shape of the holes does not need to be limited to those described above.

[0025] In the embodiment, the front side of the housing body 10 is provided with a front side rail 60. The front side rail 60 has a plurality of mounting holes 61 to which a wiring restraint tool for restraining wiring can be attached. In the embodiment, the front side rail 60 is also configured such that, like the rear side rail 50, rectangular holes and circular holes are arranged in a row with a gap between them.

[0026] The front rail 60 in the example shown in FIG. 11 has a substantially U-shaped cross section, and has a plurality of mounting holes 61 on one side for mounting a wiring restraining tool that restrains wiring. In the embodiment, the front rail 60 is fixed to the periphery of the front opening 13. More specifically, the front rail 60 is fixed so as to be located behind (inside the housing body 10) the bent portion 14 formed by bending the tip of the side plate portion 12 rising from the rear plate portion 11 (see FIG. 8). Note that any method for fixing the front rail 60 may be used. For example, the front rail 60 and the bent portion 14 or the side plate portion 12 may be fixed using a welding machine or screws.

[0027] When fixing the front rail 60, it is better to fix the surface closer to the surface having the mounting holes 61 in order to maintain strength, and deformation of the front rail 60 can be suppressed even if force is applied to a wiring restraint device attached to the mounting holes 61.

[0028] The front rail 60 does not necessarily have to have a substantially U-shaped cross section. For example, it may have a substantially L-shaped cross section. In this case, one side may have a mounting hole 61, and the other side may be fixed to the housing body 10 using a welding machine or screws.

[0029] Incidentally, a wiring restraining portion is attached to the mounting hole 51 provided in the rear rail 50. For example, the wiring can be restrained by passing a cable tie (not shown) serving as the wiring restraining portion through the mounting hole 51. In the present invention, the mounting surface 52 of the rear rail 50 is inclined toward the front opening 13, which makes such an attachment operation easier.

[0030] The wiring restraining portion attached to the rear rail 50 does not need to be a cable tie. In the example shown in Fig. 1 etc., a wiring guide member 70 is used as the wiring restraining portion. The wiring guide member 70 of the embodiment has a locking portion 71 on one side used for locking into the mounting hole 61, and a fixing portion 72 on the other side used for fixing into the mounting hole 51. Using these, the wiring guide member 70 is attached so as to span the front rail 60 and the rear rail 50.

[0031] 12 to 14 has a hook-shaped locking portion 71 at one end and a hole-shaped fixing portion 72 at the other end. The locking portion 71 is locked to the end of the square mounting hole 61 of the front rail 60, and a screw is inserted into the circular mounting hole 51 of the rear rail 50 and the fixing portion 72 to fasten and fix the wiring guide member 70 in a state of being hung across the front rail 60 and the rear rail 50. By providing the locking portion 71 that locks into the mounting hole 61 at one end of the wiring restraint portion and the fixing portion 72 for fixing at the other end in this way, the efficiency of the work can be improved.

[0032] In the embodiment, after one end of the wiring guide member 70 is hooked to restrict the position, the other end is screwed to fix the wiring guide member 70. Therefore, the time required for the work is the time required for screwing one place, and the work can be done efficiently.

[0033] In the embodiment, the end of the wiring guide member 70 on the side where the fixing portion 72 is provided is inclined to match the rear rail 50. In other words, the rear rail 50 and the fixing portion 72 are inclined toward the front opening 13, making it easy to use tools such as a screwdriver.

[0034] The wiring guide member 70 may be fixed in a state of being stretched across the front rail 60 and the rear rail 50 by engaging the locking portion 71 with the end of the square mounting hole 51 of the rear rail 50 and inserting a screw into the circular mounting hole 61 and the fixing portion 72 of the front rail 60 and fastening the screw. In this case, it is not necessary to make the end of the wiring guide member 70 on the side where the fixing portion 72 is provided inclined. In this way, the front rail 60 connected to the side where the fixing portion 72 is provided is fixed to the periphery of the front opening 13, so that the wiring guide member 70 can be easily fixed to the front rail 60.

[0035] As described above, in the embodiment, the front rail 60 having a plurality of mounting holes 61 is provided on the periphery of the front opening 13, and the wiring guide member 70 is provided across the front rail 60 and the rear rail 50. Therefore, it is possible to select the one to be used for fixing the wiring guide member 70 from the plurality of mounting holes provided in the length direction of the front rail 60 and the rear rail 50. In other words, it is possible to increase the degree of freedom in selecting the fixing position of the wiring guide member 70. Note that, in the embodiment, the position of the wiring guide member 70 can be easily changed since the amount of work required to change the position of the wiring guide member 70 is substantially the same as loosening and tightening one screw.

[0036] Meanwhile, the wiring guide member 70 of the embodiment includes a main body portion 73 extending between the locking portion 71 and the fixing portion 72. As can be seen from FIG. 14 , the main body portion 73 is configured to be positioned closer to the side plate portion 12 than the locking portion 71 and the fixing portion 72 when the wiring guide member 70 is attached to the rear rail 50. This makes it possible to ensure a space in which the wiring can be positioned up to a position close to the side plate portion 12. This makes it possible to increase the space for storing the wiring restrained by the wiring guide member 70.

[0037] Incidentally, the wiring guide member 70 does not necessarily need to abut against the front rail 60. For this reason, a structure in which a member having a generally L-shaped cross section is attached to the rear rail 50 may be used, as in the example shown in Figures 15 to 18. In the example shown in Figures 15 to 18, the wiring guide member 70 has a duct shape with multiple arms 75 arranged in a comb shape, but with a duct shape, even if there are a lot of wires, they can be brought close to the side surface of the cabinet and restrained.

[0038] 1, the cabinet 1 for storing electric and electronic equipment may include a protective plate 22. This protective plate 22 is mainly attached to cover conductive parts when the cabinet 1 for storing electric and electronic equipment is used as a switchboard or a distribution board.

[0039] 19 to 22, in the embodiment, protective plate hinge portion 24 that receives a hinge provided on protective plate 22 and protective plate receiving portion 26 that receives latch lock 25 provided on protective plate 22 are attached to front rail 60. In the embodiment, they are fixed to front rail 60 with screws 27 and are detachable. In this way, it is preferable that protective plate hinge portion 24 and the like are configured to be attachable and detachable as needed.

[0040] In the embodiment, the protective plate hinge portion 24 and the protective plate receiving portion 26 are both formed with an insertion piece 28 by bending a portion provided on one side of the member. The insertion piece 28 is made to be insertable into the mounting hole 61 provided in the front rail 60, and after insertion, it is moved along the front rail 60 to restrict movement in a direction perpendicular to the direction of movement. To make this possible, a gap of about the thickness of one side of the front rail 60 is provided between the tip side of the insertion piece 28 and one side of the member. The insertion piece 28 in the embodiment is formed by bending a tongue provided near the center of one side of the member, and the base end of the tongue is located at the end of an opening provided on one side of the member.

[0041] The insert piece 28 in the embodiment is provided with a fastening hole 29 into which the screw 27 can be inserted. In the embodiment, when the insert piece 28 is inserted into the square mounting hole 61 of the front rail 60 and moved downward, the fastening hole 29 provided in the insert piece 28 and the round mounting hole 61 of the front rail 60 are aligned in position, and the screw 27 can be inserted and attached. If the base end of the insert piece 28 is configured to be located higher than the tip in this way, when the insert piece 28 is inserted into the mounting hole 61, it moves downward by its own weight, so that it can be prevented from falling even before the screw 27 is inserted and attached, making the work easier.

[0042] 1 is configured so that the area covering the equipment is approximately the same as the area of ​​the front opening 13 as viewed from the front side, but the protective plate 22 does not necessarily have to have such a corresponding area. For this reason, multiple protective plates 22 may be arranged at a distance from each other in accordance with the positions of the conductive parts. Thus, the protective plate 22 does not necessarily have to have only one form, but if the protective plate hinge portion 24 and the protective plate receiving portion 26 are configured so that they can be appropriately attached to the front rail 60, various forms of the protective plate 22 can be accommodated.

[0043] Generally, the cabinet 1 for storing electric / electronic equipment is structured so that the door 21 cannot be opened if the user operates the handle 81 to move the locking piece 82 and the locking piece 82 fits into a notch or the like. In order to form a portion for fitting the locking piece 82, in the embodiment, the front rail 60 is provided with a locking engagement portion 63 into which the locking piece 82 can fit (see Figs. 23 and 24). In this way, processing such as providing a notch in the housing body 10 for fitting the locking piece 82 is not required, so waterproofing can be maintained.

[0044] Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be implemented in various forms. For example, the present invention can be applied to a double-door cabinet for storing electric and electronic equipment instead of a single-door cabinet. [Explanation of symbols]
