Hereinafter, preferred embodiments of the present invention will be described.
FIG. 1 is an external perspective view of an electric device housing box according to a first embodiment of the present invention. In the electric device storage box of this embodiment, a cuboid frame is formed by the columns 1, the beams 2 and the beams 3, and the top plate 4 is attached to the upper surface thereof. As shown, exterior panels such as the door 5, the side plate 6, and the back plate 7 are attached. As described above, in the electric device storage box of the present embodiment, the housing is formed by the support 1 and the beams 2 and 3, and the opening of the housing formed by them is the door 5 which is the exterior panel 6 and the back plate 7 or the like. The door 5 is attached to the support 1 by a hinge 5a, as shown in FIG.

  As shown in FIG. 3 and FIG. 4, the drainage section 14 which is a first drainage section is formed outside the opening section of the support 1, and the waterproof which is a second drainage section inside the opening section of the support 1. Piece 8 is attached. The waterproof piece 8 has an L-shaped horizontal cross section, and includes a mounting piece 8a and a vertical piece 8b. The waterproofing piece 8 is a member covering the entire height of the support 1, and the mounting piece 8 a is attached to the equipment mounting hole 9 formed in the support 1 by a screw 10. Thus, since the waterproof piece 8 is screwed to the support 1, the screw 10 is not exposed to the outside, and the waterproof property and the appearance are excellent. The equipment mounting holes 9 of the support 1 are often formed in two rows, and if the waterproof piece 8 is screwed using the equipment mounting holes 9 of the outer row, the equipment mounting holes 9 of the inner row are It can be used to install equipment.

  The vertical piece 8b of the waterproof piece 8 is attached to protrude inside the opening of the housing. 5 and 6 show the mounting state of the lower part, and FIG. 7 shows the mounting state of the upper part. In addition, how to attach the waterproofing piece 8 is not limited to the screw 10, and may be attached by using a rivet or a latch. In addition, 11 shown by these figures is a frame member for apparatus attachment fixed to the inner surface of the door 5. As shown in FIG. Moreover, 12 shown by FIG. 3, FIG. 4 is packing provided between the support | pillar 1 and an exterior panel. However, in the present invention, the packing 12 can be omitted.

  As shown in FIG. 3, the waterproofing piece 8 is located between the gap between the support 1 and the door 5 and the internal device mounted on the inside of the housing than the support 1. In this embodiment, the vertical piece 8b of the waterproofing piece 8 extends in parallel with the exterior panel, and forms a waterproofing space portion 13 with the frame member 11 provided in the door 5 which is the exterior panel. . For this reason, even when the packing 12 is deteriorated with time and the waterproofness is reduced and water infiltrates from the gap between the support 1 and the door 5, the vertical piece 8b prevents the internal equipment from being splashed with water. it can. That is, the water that has entered the inside from the gap between the support 1 and the door 5 strikes the waterproof piece 8 and flows down. For this reason, it is desirable to provide a drainage structure to the outside at the bottom. Furthermore, even when there is a large amount of water that infiltrates, the space portion 13 can cause a large amount of water to flow down in the space portion 13.

  The attachment position of the waterproofing piece 8 is not necessarily limited to the door 5 side of the support 1 and may be attached to the support 1 on the side of the exterior panel such as the side plate 6 and the back plate 7.

  Also, as shown in FIG. 8, the vertical piece 8b of the waterproof piece 8 can be mounted so as to be closer to the exterior panel. For this reason, it is possible to more reliably prevent the water that has entered the inside from the gap between the support 1 and the door 5 from being applied to the internal device by causing the entering water to flow down near the exterior panel, which is on the front side. .

  Furthermore, as shown in FIG. 9, the vertical piece 8b of the waterproof piece 8 may be bent into a crank shape. Therefore, even when the frame member 11 is not used, the waterproof space 13 can be formed. As described above, the shape of the waterproofing piece 8 is not particularly limited as long as it can prevent the water which has entered the inside from the gap between the support 1 and the door 5 from being applied to the internal device.

  In the first embodiment described above, the case has a frame structure, but in the second embodiment shown in FIG. 10, the case has a monocoque structure without a support. In the second embodiment, the housing is integrally formed with the water draining portion 14 around the opening, and the door 5 which is an exterior panel covering the opening is provided. The draining portion 14 is formed by bending the end portion of the side plate 6 in a U-shaped cross section, and the waterproof piece 8 is attached along the vertical direction inside the opening of the draining portion 14. 12 is packing.

  The structure and mounting method of the waterproofing piece 8 are the same as those of the first embodiment, and even if water intrudes from the gap between the draining portion 14 and the exterior panel, the waterproofing piece 8 prevents the water from being caught on the internal equipment. be able to.

  Also, as in the first embodiment and the second embodiment, by providing the draining portion 14 and the waterproofing piece 8, even if water intrudes from the draining portion 14, the waterproofing piece is that the water is applied to the internal device By preventing by 8, it becomes possible to take double waterproofing measures to internal equipment.

  In addition, the packing 12 may not be used for a box for storing electric devices such as cubicles that does not allow water to be splashed to the internal devices even if water is allowed to enter the case. Even in such an electrical equipment storage box, water is obtained from the gap between the support 1 or the drain 14 and the exterior panel by providing the waterproofing piece 8 as in the first and second embodiments. Even if it enters, the waterproof piece 8 can prevent water from being applied to the internal device.
