By inserting the ground wire GL from the insertion openings 45 and 45 between the fixed plate holding piece 75b and the movable plate holding piece 76b of the ground fixed plate 75 as shown in FIG. The ground movable plate 76 is screwed so as to approach the ground fixed plate 75 again, and the ground line GL is sandwiched between the ground fixed plate 75 and the ground movable plate 76.

  Further, for example, when the Y-type terminal YT is connected to the tip of the grounding wire GL, when the screw 19 is further loosened from the state shown in FIG. 1B, the grounding movable plate 76 comes into contact with the base portion 74. By restricting the operation of the grounding movable plate 76, the screw head 92 side of the screw 19 protrudes relatively forward as shown in FIG. Since a gap is formed between the plate 75 and the fixed plate continuous portion 75a, the Y-type terminal YT is connected between the screw head 92 and the fixed plate continuous portion 75a from the mounting opening 44 as shown in FIG. The Y-type terminal YT is fastened and fixed between the screw head 92 and the fixed plate continuous portion 75a by tightening the screw 19 again.

  Similarly, for example, when the O-type terminal OT is connected to the tip of the ground wire GL, when the screw 19 is further loosened from the state shown in FIG. 3A, the imaginary line in FIG. When the screw 19 is removed, the O-type terminal OT is inserted from the mounting opening 44 and aligned with the fixing plate screw hole 75c of the grounding fixing plate 75. Then, the screw 19 is inserted into the O-type terminal OT and each screw hole 75c, 76c. Then, by inserting and screwing into the screw insertion hole 74e and the screw receiving hole 83a, and tightening the screw 19 again, as shown in FIG. 4 (b), an O-type is formed between the screw head 92 and the fixed plate continuous portion 75a. Tighten and fix terminal OT.

  As described above, by positioning the ground movable plate 76 between the ground fixing plate 75 of the ground terminal 18 and the base portion 74 on the main body 22 side, the ground movable plate can be operated by operating the screw head 92 of the screw 19. 76 can be easily screwed between the ground fixing plate 75 and the base 74, and the grounding between the ground fixing plate 75 and the ground movable plate 76 can be achieved without complicating the structure of the connection terminal 18. Wiring work of the line GL becomes easy.

  That is, in the case of a conventional ground movable plate on the opposite side to the main body side with respect to the ground fixed plate, the ground movable plate is not easily separated from the ground fixed plate even when the screw is loosened. In order to hold the ground wire between the grounding fixed plate and the grounding fixed plate, the operator must move the grounding movable plate away from the grounding fixed plate, or the spring must be sandwiched between the grounding fixed plate and the grounding movable plate. On the other hand, in the present embodiment, the grounding movable plate 76 is reliably operated by operating the screw 19 without directly operating the grounding movable plate 76 or by providing a spring or the like. The space for holding the grounding wire GL between the grounding fixed plate 75 and the grounding movable plate 76 can be surely formed only by operating the screw 19. Therefore, the wiring work of the ground wire GL becomes easy.

  Further, by making the total length of the screw shaft portion 91 of the screw 19 larger than the distance between the grounding fixing plate 75 and the base portion 74, the grounding movable plate 76 moves to the base portion 74 side, that is, the rear side to the maximum, When the screw 19 is further loosened, the screw head 92 side of the screw 19 protrudes away from the ground fixing plate 75. Therefore, the ground wire GL is also provided between the ground fixing plate 75 and the screw head 92. Y-type terminal YT can be connected.

  Further, since it is not necessary to arrange a spring or the like for separating the grounding movable plate 76 from the grounding fixing plate 75 when the screw 19 is loosened, the screw 19 can be easily attached to and detached from the grounding terminal 18, and the O-type terminal. OT can be connected easily.

  The grounding fixed plate 75 is formed by bending the fixed plate holding piece portions 75b and 75b with respect to the fixed plate continuous portion 75a, and the grounding movable plate 76 is movable plate holding piece with respect to the movable plate main body portion 76a. By forming the portions 76b, 76b by bending, for example, the grounding fixing plate 75 and the grounding movable plate 75 and the grounding movable plate 75 and the grounding movable plate 75 and the grounding movable plate 75 and the grounding movable plate 75 and the grounding movable plate 75, respectively. The bending strength of the ground movable plate 76 can be improved. For this reason, when the screw 19 is tightened, the grounding fixed plate 75 and the grounding movable plate 76 are not easily deformed by the pressure sandwiching the grounding wire GL, and the grounding wire GL is interposed between the grounding fixed plate 75 and the grounding movable plate 76. Can be held securely.

  In particular, since the size of the main body 15 and the plug mounting portion 25 is determined by JIS, the space for placing the grounding fixed plate 75 and the grounding movable plate 76 is limited. This limited space can be used effectively by eliminating the need to increase the thickness of the movable plate 76.

  In addition, since the upper and lower edges of the movable ground plate 76 are in contact with the upper edge 35 and the lower edge 37 of the cover 21 of the main body 15, even when an external force is applied to the ground wire GL, the upper edge 35 and the lower edge The external force can be received by the portion 37, and the grounding movable plate 76 is not deformed or falls within the ground terminal hole 26.

  Next, FIG. 9 and FIG. 10 show a second embodiment, FIG. 9 is a front view of the outlet, FIG. 10 is a cross-sectional view taken along the line AA of FIG. FIG. 4B is a cross-sectional view showing a state in which the ground wire is inserted into each insertion hole of the outlet, and FIG. 5C is a cross-sectional view showing a state in which the ground wire of the outlet is fixed. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In the second embodiment, in the first embodiment, a fixed plate insertion hole 95 into which the ground wire GL is inserted is formed in the ground fixed plate 75, and the ground movable plate 76 is grounded. A movable plate insertion hole 96 into which the line GL is inserted is formed.

  The fixing plate insertion holes 95 are formed in the fixing plate holding piece portions 75b of the grounding fixing plate 75 in the shape of round holes that are long in the vertical direction.

  The movable plate insertion holes 96 are formed in the movable plate holding piece portion 76b of the ground movable plate 76 in the shape of a round hole that is long in the vertical direction.

  The insertion holes 95 and 96 have substantially the same size, and are formed at positions where their axes are deviated with the screw holes 75c and 76c being coaxial. In other words, the insertion holes 95 and 96 are arranged in a direction intersecting with the axis of the screw holes 75c and 76c, in this embodiment, on an axis inclined downward from the front side to the rear side. That is, the fixed plate insertion hole 95 is positioned above the movable plate insertion hole 96 in a state where the axes of the screw holes 75c and 76c are aligned. For this reason, the insertion holes 95 and 96 are arranged on substantially the same axis line with the outlet 11 looking down from the upper front.

  Then, when inserting the ground wire GL, as shown in FIG. 10 (a), the screw 19 is loosened and the ground movable plate 76 is moved rearward as shown in FIG. 10 (b). Then, the front end side of the grounding line GL is linearly inserted from the upper front side into the fixed plate insertion hole 95 and the movable plate insertion hole 96. In this state, the screw 19 is tightened as shown in FIG. By moving the plate 76 to the front side, the relative position between the grounding fixed plate 75 and the grounding movable plate 76, that is, the relative positions of the insertion holes 95 and 96, changes to the insertion holes 95 and 96 of the grounding wire GL. The inserted part is sandwiched so that it is bent at the step between the grounding fixed plate 75 and the grounding movable plate 76, and the tip of the grounding wire GL is caught by the edge part of the movable plate insertion hole 96 to prevent it from coming off Is done.

  Thus, by forming the insertion holes 95, 96 at positions where the axes are shifted from each other with the screw holes 75c, 76c being coaxial, the ground wire GL is inserted in the insertion direction of the plug blade over the insertion holes 95, 96. When the screw 19 is tightened in this inserted state, the ground wire GL can be brought into close contact with the step portion generated between the ground fixed plate 75 and the ground movable plate 76, and the insertion hole 95 The grounding line GL can be hooked on the edges of 96 and 96, so that the wiring workability of the grounding line GL can be improved.

  That is, the outlet 11 is generally formed at a position closer to the lower side of the wall surface, and when wiring the ground line GL, the worker looks down on the outlet 11 from the upper side. For this reason, the main body 22 is attached to the construction surface with the grounding fixed plate 75 and the grounding movable plate 76 side as the lower side, and the fixed plate insertion hole 95 is set on the upper side with respect to the movable plate insertion hole 96. Since the insertion holes 95 and 96 are arranged in a straight line while looking at the outlet 11, not only the operator can easily grasp the insertion position of the ground wire GL, but also the ground wire GL is actually wired. Even in this case, since the ground wire GL can be easily inserted from the upper side through the insertion holes 95 and 96, the wiring workability of the ground wire GL can be further improved.

  Furthermore, since the ground wire GL does not protrude below the outlet 11, the outlet 11 can be installed even in a relatively small space.

  In addition, since the ground line GL is wired in the direction opposite to the downward direction, which is the direction of gravity, the ground line GL can be hardly dropped from the insertion holes 95 and 96.

  Compared to the case where the ground wire is fixed between the ground fixed plate and the ground movable plate, the ground movable plate 76 can be reliably reduced without downsizing the ground movable plate 76 or making the ground wire GL easier to hook. Can connect.

  In the second embodiment, if the insertion holes 95 and 96 are positions where the axes are shifted from each other with the screw holes 75c and 76c coaxially arranged, the fixed plate insertion hole 95 is replaced with the movable plate insertion hole. It is not necessary to set the upper side of 96.

  In each of the above embodiments, the pin receiving portions 72 and 73, the base portion 74, the ground fixing plate 75, and the like are integrally formed with respect to the terminal body 71 of the ground terminal 18, but these are electrically connected. If it is, each may be a separate body.

  Furthermore, the number of plug mounting portions 25 may be one, or three or more. In this case, pin receiving portions and the like are provided corresponding to the number of plug mounting portions 25.
