Description

  The present invention relates to improvement of an outlet box having an outlet for distributing or extending a power cord to other cords such as a power cord for lighting equipment, etc., particularly outdoors, and particularly ease of handling. It is related with improving waterproofness while ensuring.

  When electrical equipment such as lighting equipment is installed outdoors, electricity may be supplied from a single power source to a plurality of electrical equipments using an outlet box having a plurality of plug insertion openings. Since such an outlet box is installed outdoors, it is necessary to take sufficient waterproof measures against the electrical connection portion.

  As such an outlet box, an outlet box is proposed that includes a pedestal that is installed on the ground and supports the outlet, and a cover that covers the pedestal while providing a gap between the pedestal (for example, Patent Document 1). reference).

  However, in this prior art, the plug outlet of the outlet is set on the upper side of the pedestal, and the cover part is supported by this pedestal and covers the pedestal. In order to insert the plug of the power cord of the electrical equipment, it was necessary to attach the cover part again after inserting it with the cover part removed. For this reason, there is a problem that it takes time and labor to connect the power cord.

  On the other hand, in order to solve this problem, it is conceivable that the outlet plug outlet is exposed to the outside such as the side or bottom surface of the outlet box, but this reduces the waterproofness. There is a fear. In particular, in this prior art, when the plug insertion port is arranged so as to face downward from the pedestal, a sufficient space for insertion cannot be secured, and the lower end of the cover portion for waterproofing is provided on the pedestal. Since it is located above the lower end of the water, if rainwater or the like accumulates, it may be submerged from the outlet and affect the electrical connection.

  Furthermore, in this prior art, since the cover part is supported by a pedestal arranged in contact with the ground, and the installation surface of the pedestal is located inside the cover part, when removing the outlet box from the installation surface, Once the cover part is removed from the pedestal, it is necessary to further remove the pedestal from the installation surface, and there is a problem that it takes time and effort to move the installation location and to remove it from the installation location.

As described above, conventionally, it has been a reality that an outdoor outlet box having both easy handling and sufficient waterproofness is not necessarily provided.

Therefore, there is an advantage that waterproofness can be improved while ensuring ease of handling.

  According to the present invention, since the leg portion is provided as described above, it can be easily fixed to the installation surface, and the board can be adjusted by adjusting the insertion depth of the leg portion to the grounding surface. The distance from the ground can be set higher to avoid the influence of rainwater, and at the same time, there is an advantage that operations such as drawing out the power cord and plugging are facilitated.

  The embodiment of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 3 show an outlet box 10 of the present invention. The outlet box 10 includes a power cord 12 and the power cord 12 shown in the figure. And an outlet (distribution unit) 14 connected to another power cord. As shown in FIGS. 2 and 3, the outlet box 10 further includes a substrate 16 that supports the outlet 14 and a cover portion 18 that covers the substrate 16.

  As shown in FIGS. 2 and 3, the outlet 14 is installed on the board 14, and only the plug insertion port 20 for inserting a power cord of another electric device (not shown) faces downward from the board 16. Are arranged as follows. Therefore, as can be seen from FIGS. 2 and 3, only the plug insertion port 20 faces the outside from the lower side of the outlet box 10, and the outlet 14 is located on the back side of the board 16 as viewed from the lower side of the board 16 (the upper side of the board 16. ). Therefore, the power cord of another electrical device to be connected can be easily inserted / removed into / from the plug insertion port 20 without removing the cover 18. In the illustrated embodiment, four insertion ports 20 are set as the insertion port 20, but the number of installed ports and the shape of the insertion port 20 are not particularly limited, and may be appropriately set as necessary. Can be set. Further, a cover for preventing entry of wind and rain when not in use can be attached to the insertion port 20.

  On the other hand, as shown in FIG. 2 in particular, the cover portion 18 includes an upper outlet storage portion 18A and a side skirt 18B formed so as to extend from below with a slight step from the outlet storage portion 18A. doing. As shown in FIG. 2, the substrate 16 is supported in the cover portion 18 by the cover portion 18.
