And a connecting portion 33 that is rotatably supported when viewed from the left-right direction. Hereinafter, the shape of the door body 3 will be described in detail with reference to the direction at the closed position.

  The main body 31 is provided with a rectangular cutout 31b whose upper and lower dimensions of the central portion in the left-right direction are smaller than the left and right ends, and the connecting portion 33 is located on the left and right of the cutout 31b. It is connected to. That is, the main body 31 is connected to the connecting portion 33 at the end near the voltage side plug blade insertion port 10a and the ground side plug blade insertion port 10b, and the main body portion 31 is shown in FIG. From the closed position shown, by rotating about 90 degrees clockwise as viewed from the right with respect to the housing 1 around the upper end connected to the connecting portion 33, the ground terminal housing recess 12 is opened and the ground terminal 2 is Displace to open position to expose. The inner surface (upper surface) of the notch 31 b forms a through hole communicating with the ground plug blade insertion hole 10 c between the ground plug blade insertion recess 10 d of the housing 1. The notch 31b exposes the left and right portions of the ground plug blade insertion recess 10d in the housing 1 to the front. The shape of the ground terminal storage recess 12 is adapted to the shape of the door body 3. When the main body 31 of the door 3 is in the closed position, the main body 31 of the door 3 is stored in the ground terminal storage recess 12. Thus, the front surface of the main body 31 of the door body 3 and the front surface of the housing 1 are substantially flush.

Displacement is prohibited, and it is difficult for stress to be applied to the locked convex portion 34, and damage to the locked convex portion 34 is suppressed. Further, since the restricted convex portion 35 is L-shaped when viewed from the rear, the mechanical strength of the restricted convex portion 35 is increased as compared with the case where the restricted convex portion 35 is a rectangular parallelepiped shape as shown in FIG. While maintaining, sink marks are less likely to occur on the surface of the restricted convex portion 35 when the door body 3 is molded.

  Further, a guide projection 36 projects rearward at the center in the left-right direction at the upper end of the main body 31. The guide protrusion 36 is formed in a U-shape in which both left and right end portions protrude downward from the center portion. Since the guide protrusion 36 is provided, the plug blade Pc of the ground electrode is guided by the guide protrusion 36 when the plug P is connected, as shown in FIG. 8A. Therefore, as shown in FIG. Compared with the case where the guide projection 36 is not provided, the plug blade Pc of the ground electrode is less likely to be caught on the inner surface of the ground terminal storage recess 12 or the ground terminal 2. Further, the guide protrusion 36 improves the mechanical strength of the door body 3 and suppresses breakage.

  According to the above configuration, the distance between the grounding terminal 2 and the grounding plug blade insertion port 10c is smaller than when the lower grounding blade insertion port 10c is provided outside the grounding terminal receiving recess 12 as in the conventional example. The size can be reduced. Further, since there is no wall partitioning the ground terminal storage recess 12 and the lower ground plug blade insertion slot 10c, the housing 1 is hardly damaged by the plug blade Pc of the ground electrode when the plug P is inserted and removed. Further, since the guide protrusion 36 is provided on the door body 3, the plug blade Pc of the ground electrode is not easily caught on the inner surface of the ground terminal storage recess 12 or the ground terminal 2 when the plug P is inserted and removed. In addition, the door body 3 is made of a thermoplastic resin rich in elasticity compared to the thermosetting resin to suppress the damage of the door body 3, while the elasticity is poor compared to the thermoplastic resin, but the thermosetting has high tracking resistance. The housing 1 is made of a functional resin to suppress tracking.

  The shape of the door body 3 is not limited to that of the present embodiment. For example, as shown in FIG. 9, the left and right dimensions of the notch 31b of the main body 31 of the door body 3 are the same as the left and right dimensions of the ground plug blade insertion port 10c. It may be the same level. In this case, not only the lower part of the opening edge of the plug blade insertion port 10c but also the left and right are constituted by the door body 3. If this structure is employ | adopted, the width dimension of the connection part 33 can be taken large compared with the structure of FIGS. 1-5, and the mechanical strength of the door body 3 can be improved.

  Alternatively, as shown in FIGS. 10 to 12, instead of providing the notch 31 b, the main body 31 of the door body 3 has a substantially rectangular shape, and a plug blade connected to the lower ground terminal insertion port 10 c is inserted. A grounding plug blade insertion hole 31 c may be provided through the main body 31 of the door body 3. In the above example, the guide protrusion 36 is provided below the ground plug blade insertion hole 31c. In this case, in addition to the guide protrusion 36, the inner surface of the ground plug blade insertion hole 31c also serves as a guide portion in the claims. If this configuration is adopted, the mechanical strength can be further improved by making the width of the connecting portion 33 larger than in the case of FIG. Further, as compared with the case where the cover 1b is shaped as shown in FIG. 11 and the door 3 is shaped as shown in FIG. 3, the peripheral portion of the ground terminal insertion port 10c on the lower side as much as the door 3 is overlapped. The mechanical strength of is improved.

  Further, if the coupling convex portion is detachably coupled to the housing 1 and has an action of holding the door body 3 in the closed position, the locked portion held by the housing 1 by locking as in the above embodiment. It is not restricted to the convex part 34, For example, you may couple | bond with the housing 1 by other well-known means like a fitting.
