Can be reduced.

Further, by providing the blade receiving portions 514 and 524 in rotational symmetry when viewed from the plug insertion surface 21 side, the plug insertion surface 21 can be made into a square, polygon, circle, or the like instead of an elongated shape. , The entire outlet 1 can be made compact. Further, when the plugs are inserted into the slits 22 and 23 at the same time, other plugs do not get in the way.

In the present embodiment, two blade receiving portions 514 and 524 are provided on each side of the square shape drawn by the loci of the slits 22 and 23, but the present invention is not limited to this, and each side of the square shape is not limited to this. It may be provided one by one, or three or more may be provided. Further, the loci of the slits 22 and 23 may be circular, and the blade receiving portions 514 and 524 may be provided on the circumference at equal intervals. Further, when the loci of the slits 22 and 23 are rectangular, two blade receiving portions 514 and 524 may be provided on the long side and one on the short side, or they may be arranged in another rotationally symmetric manner. By providing the plurality of blade receiving portions 514 and 524 rotationally symmetrically in this way, the entire outlet 1 can be made more compact than when they are provided in parallel, and even if the plugs are inserted into the slits 22 and 23 at the same time, other parts can be used. The plug does not get in the way.

As described above, the outlet 1 has a simple structure in which the blade receiving members 51 and 52 of 2 are provided in the main body case 10, but a plurality of plugs are simultaneously inserted into different positions of the slits 22 and 23. It is possible to supply electric power to a plurality of electric devices connected to a plurality of plugs. Since the circuit can be simplified, the number of parts and the number of soldering points can be reduced, the manufacturing cost can be reduced, and the safety can be improved.

It should be noted that the above-described embodiment is only an example, and various modifications can be made without changing the gist of the invention described in the claims.
For example, the shape of the main body case 10 is only an example. The upper cover 20, the lower cover 30, and the pedestal 40 shown in FIG. 1 may be housed in a slightly larger box as the main body case, and the main body case may be placed on the floor and used as a power strip.
Further, of the slits 22 and 23, the portions where the blade receiving portions 514 and 524 are not provided at the opposite positions may be narrowed in width or made into recesses so that the plug blade of the plug cannot be inserted, and can be distinguished. You may change the color as follows.

Further, a pilot lamp for notifying a continuity state or a warning may be provided at the center of the plug insertion surface 21.
