  The outlet A shown in FIGS. 8 and 9 has a configuration other than that shown in FIGS. 1 to 7 except that the shape of the protector 20 is different from the shape of the protector 20 of the outlet A shown in FIGS. 7 has the same or substantially the same configuration as that of the outlet A shown in FIG. 7. In the same manner, the plug B can be inserted and the power source can be taken out and used, and has the same operations and effects.

  Therefore, the same reference numerals are given to the same or substantially the same components as the outlet A in FIGS. 1 to 7, and the description thereof is omitted.

  In the outlet A shown in FIGS. 8 and 9, the elongated plate-like portion along which the protector 20 extends along the outer side of one set of the blade receiving hole ports 11 a arranged in the vertical direction. 22a, an elongated plate-like portion 22b along the outer side of the other blade receiving hole 11a, and the elongated plate-like portions 22a, 22b, and one end side of each of the elongated plate-like portions 22a, 22b. Are formed as a block-like protective body 20 ″ provided with a wide plate-like plate-like portion 22c which is provided so as to be continuous in series and closes a part between the blade receiving hole openings 11a.

  The block-shaped protector 20 ″ according to this illustrated example is configured such that the wide plate-like plate portion 22c has an inverted trapezoidal shape with its lower side positioned flush with the lower end surfaces of the elongated plate-like portions 22a and 22b. In addition, the elongated plate-like portion 22a and the elongated plate are formed by plate-like continuous portions 22d along the upper edge of the blade receiving hole 11a provided on both sides of the upper end of the wide plate-like plate-like portion 22c. It is comprised so that it may be continued in series by the shape part 22b.

  Then, a rod 23 provided with means for urging the protective body 20 to protrude forward and a base plate 32 provided with a movable contact 31b constituting the opening / closing device 30 on the back side of the wide plate-like portion 22c. Is provided in a protruding state.

  In the outlet A having such a configuration, in combination with the features of the outlet A shown in FIGS. 1 to 7, the elongated plate-like portions 22a and 22b in the wide plate-like plate portion 22c face each other. The surface 22c ′ and the surface 22d ′ on the inner side of the plate-like connecting portion 22d, that is, the surface 22d ′ on the blade receiving hole port 11a side guide the plug blade 41 ′ of the plug B to the blade receiving hole 11. It functions as part w.

  Further, the block-shaped protective body 20 ″ constituting the outlet A protects the blade receiving hole 11 from both sides, and more reliably prevents the insertion of a conductive piece or the like into the blade receiving hole 11. Further, it is possible to more reliably prevent problems such as cotton dust entering between the plug B inserted into the outlet A and the outlet A.

  In addition, the block-shaped protector 20 ″ constituting the outlet A can be conveniently provided with the rod 23 on the wide plate-like plate-like portion 22c having the inverted trapezoidal shape, so that the protector 20 can be in a smoother operating state. it can.
