[Modes for carrying out the invention]

[0013] Embodiments for carrying out the invention are shown below. As can be seen from Figures 1 to 6, the electrical and electronic equipment storage box 1 of this embodiment has a housing body 10 having an upper surface 11, a lower surface 12, a left surface 13, a right surface 14, and a rear surface 15, and a door 20 attached to the housing body 10, and inside the box, there is an electrical and electronic equipment 50 powered by electric wires 81 wired from outside the box, and a circuit board 60 for fixing the electrical and electronic equipment 50. Furthermore, the circuit board 60 of this electrical and electronic equipment storage box 1 is attached to any of the above surfaces (upper surface 11, lower surface 12, left surface 13, right surface 14, rear surface 15) of the housing body 10, and a wire storage space Rw is formed between the circuit board 60 and the surface to which the circuit board 60 is attached, for storing the electric wires 81 that supply power to the electrical and electronic equipment 50 fixed to the circuit board 60. For this reason, it is possible to reduce the risk of electric shock when connecting portable equipment 91 etc. to the electrical and electronic equipment 50 provided inside the electrical and electronic equipment storage box 1.

[0014] The following describes the electrical and electronic equipment storage box 1 of this embodiment in order. The electrical and electronic equipment storage box 1 of this embodiment is formed by a housing body 10 in which the storage space is partitioned by five surfaces: the top surface 11, the bottom surface 12, the left surface 13, the right surface 14, and the rear surface 15, and a door 20 that is attached so as to cover an opening provided on the front side of the housing body 10. At least electrical and electronic equipment 50 and a circuit board 60 are stored in the storage space provided in the housing body 10. The box of this embodiment can be locked by operating a locking device provided on the door 20.

[0015] As can be seen from Figures 1 to 4, the electrical and electronic equipment housing box 1 of this embodiment is equipped with a circuit board mounting bracket 31 for mounting a circuit board 60. In this example, the circuit board mounting bracket 31 is provided on the rear surface 15, but it can be provided on an appropriate surface according to the mounting location of the circuit board 60. Providing the circuit board mounting bracket 31 on at least one surface makes it easy to attach and detach the circuit board 60.

[0016] In addition, in the embodiment, a water drainage member 32 capable of discharging water inside the box body to the outside of the box body is attached to the box body so as to cope with condensation occurring inside the box body and intrusion of water from the outside of the box body into the box body. The water drainage member 32 is usually attached to the lower surface 12 of the housing main body 10, but it may be attached to other surfaces.

[0017] Further, the box body of the embodiment is made of metal, but since a paint is applied, it is difficult to conduct electricity. Therefore, an earth terminal 33 is provided inside the box body so that the electrical and electronic equipment 50 arranged inside the box body can be grounded.

[0018] Moreover, the electric and electronic equipment storage box 1 of the embodiment includes a mounting member 34 for mounting a portable device 91 to be stored inside the box body. In the example shown in FIGS. 1 to 6, the mounting member 34 is attached to the substrate 60, but it may be attached to other locations. Note that what is provided in the electric and electronic equipment storage box 1 is not limited to these.

[0019] By connecting an electric wire 81 wired inside the box body to the electrical and electronic equipment 50, power can be supplied to the electrical and electronic equipment 50. Further, by connecting a portable device 91 to the electrical and electronic equipment 50 used for supplying electricity, power can be supplied to the portable device 91.

[0020] The electrical and electronic equipment 50 is, for example, a power outlet, and by connecting the power plug of the portable device 91, power can be supplied to the portable device 91. Also, the electrical and electronic equipment 50 may be a charging device or the like capable of supplying power to the portable device 91. Furthermore, it may be power distribution equipment such as a breaker, a terminal block, or a relay. In this case, from the viewpoint of preventing electric shock, it is preferable to provide terminals (such as quick-connect terminals) that do not require tools so that the terminals of the portable device 91 can be easily connected.

[0021] The term "portable device 91" primarily refers to portable devices such as batteries or devices equipped with batteries, but it may also refer to devices without batteries. However, it is preferable that the device be housed inside the enclosure and powered by the electrical and electronic equipment 50.

[0022] A circuit board 60 on which electrical and electronic equipment 50 is fixed is attached to the housing body 10, but the circuit board 60 can be attached to any of the surfaces that make up the housing body 10. In the examples shown in Figures 1 to 4, the circuit board 60 is attached to the rear surface 15 of the housing body 10, but it may be attached to any of the top, bottom, left, or right surfaces.

[0023] The circuit board 60 is mounted such that a space is formed between the circuit board 60 and the surface on which it is attached. This space between the circuit board 60 and the surface on which it is attached is intended to serve as a wire storage space Rw for housing the electric wires 81 that are routed from outside the enclosure to the electrical and electronic equipment 50. In the examples shown in Figures 1 to 6, the wire storage space Rw is formed between the circuit board 60 and the rear surface 15, making the electric wires 81 less visible from the opening side and providing a superior aesthetic appearance, which is preferable.

[0024] Preferably, the wire storage space Rw houses a wire connection part 52 used to connect the electrical and electronic equipment 50 with wires 81 wired from outside the enclosure. This is because, when wires 81 brought from outside the main enclosure 10 are connected to the electrical and electronic equipment 50, the connection point increases the risk of electric shock. By housing this point in the wire storage space Rw, the risk of electric shock during normal use can be reduced. In the example shown in Figure 5, a hole 64 through which wires can be inserted is provided in the circuit board 60, allowing wires to be routed from the rear of the electrical and electronic equipment 50 to the wire storage space Rw.

[0025] The wire connection section 52 may be a terminal block or a relay or other power distribution equipment, but it is preferable that it be a connector that connects the wire 81 wired from outside the enclosure to the wire with equipment attached to the electrical and electronic equipment 50. Connecting the wire 81 wired from outside the enclosure to the wire with equipment attached to the electrical and electronic equipment 50 using a connector makes the connection work easier.

[0026] Incidentally, in order to route the electric wire 81 from outside the enclosure to the electric wire storage space Rw, an insertion hole 16 is usually provided on one of the surfaces constituting the enclosure body 10 for inserting the electric wire 81. In contrast, it is preferable to provide a notch 62 on the circuit board 60 at a location opposite to the surface with the insertion hole 16. This makes it easier to route the electric wire 81 to the electric wire storage space Rw.

[0027] In the examples shown in Figures 1 to 6, a through-hole 16 for passing the electric wire 81 is provided on the lower surface 12 of the housing body 10, and a notch 62 is provided on the lower surface of the circuit board 60, which is opposite the lower surface 12. This makes it easy to route the electric wire 81 from the outside of the housing body 10 to the electric wire storage space Rw. Note that the through-hole 16 is not necessarily provided on the lower surface 12, but the notch 62 can be provided at a location opposite the surface where the through-hole 16 is provided. For example, if the through-hole 16 is provided on the upper surface 11 of the housing body 10, it is preferable to provide the notch 62 on the upper surface of the circuit board 60. Note that if the through-hole 16 is provided at a position corresponding to the electric wire storage space Rw on the surface to which the circuit board 60 is attached, it is not necessary to provide the notch 62 on the circuit board 60.

[0028] Incidentally, the electrical and electronic equipment storage box 1 of this embodiment has an equipment storage space Rd for storing portable equipment 91. More specifically, an equipment storage space Rd for storing portable equipment 91 connected to and powered by electrical and electronic equipment 50 is formed between the circuit board 60 and the surface facing the surface to which the circuit board 60 is attached or the door 20.

[0029] In the examples shown in Figures 1 to 6, the circuit board 60 is mounted on the rear surface 15, so the surface opposite to the surface on which the circuit board 60 is mounted, or the door 20, refers to the door 20. In other words, an equipment storage space Rd is formed between the circuit board 60 and the door 20. Furthermore, if the circuit board 60 is mounted on the left surface 13, the opposite surface is the right surface 14, and if the circuit board 60 is mounted on the top surface 11, the opposite surface is the bottom surface 12.

[0030] The storage space inside the enclosure is divided into a wire storage space Rw and an equipment storage space Rd, with the circuit board 60 as the boundary. For example, in the examples shown in Figures 1 to 6, the wire storage space Rw is formed on the rear side of the circuit board 60, and the equipment storage space Rd is formed on the front side of the circuit board 60.

[0031] Preferably, a mounting member 34 for placing the portable equipment 91 is provided in the equipment storage space Rd. This mounting member 34 may be fixed to the circuit board 60, as can be seen from Figure 4. In this way, the mounting member 34 can be attached to the circuit board 60 outside the housing body 10, and then the circuit board 60 can be attached to the housing body 10, thereby reducing the amount of work that needs to be done inside the housing body 10.

[0032] The screws 71 used to fix the mounting member 34 to the substrate 60 penetrate the substrate 60, and their threaded portion or tip is located in the wire storage space Rw. As a result, there is a risk that the wires 81 may be damaged by the threaded portion or tip, so it is preferable to attach protective caps 72 to the threaded portion or tip. This prevents damage to the wires 81 that are routed into the wire storage space Rw.

[0033] Furthermore, it is preferable to attach protective caps not only to the screws 71 used to fix the mounting member 34, but also to any other components or parts that may damage the electric wire 81. In particular, since the circuit board 60 is a component that may be moved, it is preferable to attach protective caps to any components attached to the circuit board 60.

[0034] Here, we will describe an example of a method for wiring electric wires 81 between a circuit board 60 and the surface to which the circuit board 60 is attached. More specifically, we will describe an example of a wiring method for electric wires 81 for supplying power to electrical and electronic equipment 50 fixed to a circuit board 60, which is located inside a box having a housing body 10 with a top surface 11, a bottom surface 12, a left surface 13, a right surface 14, and a rear surface 15, and a door 20 attached to the housing body 10.

[0035] First, the electrical and electronic equipment storage box 1 is installed in the designated location. When installing on a wall or support column, the rear panel 15, etc., can be fixed to the wall or support column. For freestanding installation, anchor fixing via a base is preferable.

[0036] After installing the electrical and electronic equipment enclosure 1 in the designated location, the circuit board 60 mounted on the enclosure body 10 of the electrical and electronic equipment enclosure 1 is moved to expose its surface. If the circuit board 60 and the surface are fixed entirely with screws, the circuit board 60 may be removed from the enclosure body 10, exposing the entire surface (see Figure 7). If the circuit board 60 and the surface are connected by a hinge 74, the circuit board 60 may be tilted to expose only a portion of the surface (see Figure 8).

[0037] After moving the circuit board 60 to expose at least a portion of its surface, the wires 81 that were routed from outside the enclosure to inside the enclosure are connected to the electrical and electronic equipment 50 fixed to the circuit board 60. The wires 81 that were routed from outside the enclosure to inside the enclosure may be connected directly to the electrical and electronic equipment 50, or they may be connected via the wire connection part 52.

[0038] Afterward, the circuit board 60 is returned to its original position and secured. At this time, it is preferable that the electric wire 81 is routed so that it passes through the insertion hole 16 provided in the housing body 10 and the notch 62 provided in the circuit board 60 and is located in the electric wire storage space Rw.

[0039] The wiring method is not limited to the method described above. However, it is preferable to include the steps of: removing the circuit board 60 from the surface to which it is attached and exposing the surface; inserting the electric wire 81 from outside the box into the box; connecting the electrical and electronic equipment 50 and the electric wire 81; and attaching the circuit board 60 to the surface and positioning a portion of the electric wire 81 connected to the electrical and electronic equipment 50 between the circuit board 60 and the surface to which the circuit board 60 is attached.

[0040] The present invention has been described above with reference to the embodiments, but the present invention is not limited to the above embodiments and can be made into various forms. For example, multiple through holes may be provided. Also, through holes may be provided so as to span multiple surfaces, or independent through holes may be provided on each of the multiple surfaces.

[0041] Furthermore, by placing the ground terminal in the space between the circuit board and the surface to which the circuit board is mounted, the wiring from the electrical and electronic equipment 50 to the ground terminal can also be hidden by the circuit board. [Explanation of symbols]
