The ground terminal plate 21 is mechanically and electrically connected to the ground conductive block 5c on the lower side of the lower blade receiver 53, for example, by caulking.

また、扉体３は熱可塑性樹脂からなり、図３に示すように、端子収納凹部１２を覆う本体部３１と、左右に並べて２個設けられそれぞれハウジング１に結合する固定部３２と、各固定部３２と本体部３１との間にそれぞれ介在して他の部位よりも薄肉に形成されて接地端子２を覆う閉位置と接地端子２を露出させる開位置との間で本体部３１を固定部３２に対して左右方向から見て回動可能に支持する連結部３３とを備える。以下、扉体３の形状について、閉位置での方向を基準として詳しく説明する。 Further, the door body 3 is made of a thermoplastic resin, and as shown in FIG. 3, as shown in FIG. 3, a main body portion 31 that covers the terminal housing recess 12, two fixing portions 32 arranged side by side and coupled to the housing 1, respectively, The main body 31 is fixed between a closed position that is interposed between the portion 32 and the main body 31 and is thinner than other portions and covers the ground terminal 2 and an open position that exposes the ground terminal 2. 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.

本体部３１には、左右方向の中央部の上下の寸法を左右両端部よりも小さくする矩形状の切り欠き３１ｂが上端に設けられており、連結部３３は切り欠き３１ｂの左右において本体部３１に連結されている。すなわち、本体部３１は電圧側栓刃挿入口１０ａ及び接地側栓刃挿入口１０ｂに近い側の端部において連結部３３に連結されているのであり、本体部３１は、図１（ａ）に示す閉位置から、連結部３３に連結された上端を中心としてハウジング１に対し右方から見て時計回りに９０度程度回動することにより、接地端子収納凹部１２を開放して接地端子２を露出させる開位置に変位する。切り欠き３１ｂの内面（上面）は、接地栓刃挿通穴１０ｃに連通した貫通穴を、ハウジング１の接地栓刃挿通凹部１０ｄとの間に構成する。また、切り欠き３１ｂは、ハウジング１において接地栓刃挿通凹部１０ｄの左右の部位を前方に露出させる。接地端子収納凹部１２の形状は扉体３の形状に合わせた形状となっており、扉体３の本体部３１が閉位置にあるときには扉体３の本体部３１は接地端子収納凹部１２に収納されて扉体３の本体部３１の前面とハウジング１の前面とが略面一となる。 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.

各固定部３２の先部には、それぞれ左右方向であって他方の固定部３２に近付く方向に係合爪３２ａが突設されている。カバー１ｂにおいて接地端子穴１２ｂの上側には結合穴１４が左右に並べて２個、前後に貫設されており、扉体３は結合穴１４に固定部３２が挿通されて各係合爪３２ａがそれぞれカバー１ｂの後面に係合することにより、扉体３はハウジング１に結合している。また、本体部３１の下端には、接地端子２に接続された接地線が挿通される穴を端子収納凹部１２の下端との間に形成する挿通切り欠き３１ａが、左右に並べて２個設けられている。 Engagement claws 32a project from the front portions of the fixing portions 32 in the left-right direction and in the direction approaching the other fixing portion 32, respectively. In the cover 1b, two coupling holes 14 are arranged on the upper side of the ground terminal hole 12b side by side in the front and rear, and the door 3 has a fixing portion 32 inserted through the coupling hole 14 so that each engagement claw 32a is connected to the cover 1b. The door body 3 is coupled to the housing 1 by engaging with the rear surface of the cover 1b. In addition, two insertion notches 31a are formed at the lower end of the main body 31. The insertion notches 31a are formed on the left and right sides to form a hole through which the ground wire connected to the ground terminal 2 is inserted between the lower end of the terminal storage recess 12. ing.

さらに、本体部３１の左右両端部には、下端部から後方へそれぞれ結合凸部としての被係止凸部３４が突設され、各被係止突部３４の後端には、被係止爪３４ａが下方へ突設されている。また、図４及び図５に示すように、接地端子穴１２ｂの内面において、左右両端部には、それぞれ係止凸部１２ｃが上方へ突設されている。扉体３の本体部３１が閉位置にある状態（扉体３を閉じた状態）では、図６に示すように被係止爪３４ａが係止凸部１２ｃに係脱自在に係止される（すなわち、被係止爪３４ａが係止凸部１２ｃの後側に位置する）ことにより、扉体３を開く方向への本体部３１の回動が禁止される。係止凸部１２ｃに対する被係止爪３４ａの係脱は、本体部３１に力を加えて被係止凸部３４を弾性変形させることにより行う。 Further, at both left and right end portions of the main body portion 31, locking projections 34 as projecting projections are projected from the lower end portion to the rear, and at the rear ends of the locking projection portions 34, The claw 34a protrudes downward. Further, as shown in FIGS. 4 and 5, on the inner surface of the grounding terminal hole 12 b, locking projections 12 c are projected upward at the left and right ends, respectively. In a state where the main body 31 of the door body 3 is in the closed position (a state where the door body 3 is closed), as shown in FIG. 6, the to-be-latched claw 34 a is removably locked to the locking convex portion 12 c. (That is, the to-be-latched nail | claw 34a is located in the back side of the latching convex part 12c), and rotation of the main-body part 31 to the direction which opens the door body 3 is prohibited. Engagement / disengagement of the latching claw 34a with respect to the latching convex portion 12c is performed by applying a force to the main body portion 31 and elastically deforming the latched convex portion 34.

また、本体部３１の左右両端部において被係止凸部３４の上側には、それぞれ後方から見てＬ字形状の被制限凸部３５が突設されている。図４及び図５に示すように、接地端子穴１２ｂの内面には、扉体３を閉じた状態で被係止凸部３４が係入する制限凹部１２ｄが設けられている。扉体３の本体部３１が閉位置において下向きの力を受けた場合、制限凹部１２ｄの下側の内面に被係止凸部３４が当接することにより、ハウジング１に対する本体部３１の下方への変位は禁止され、被係止凸部３４に応力がかかりにくくなって被係止凸部３４の破損が抑制されている。また、被制限凸部３５を後方から見てＬ字形状としたことにより、図７に示すように被制限凸部３５を直方体形状とする場合に比べ、被制限凸部３５の機械的強度を維持しながらも、扉体３の成型時に被制限凸部３５の表面にヒケが生じにくくなっている。 Further, at the left and right end portions of the main body 31, L-shaped restricted convex portions 35 project from the locked convex portions 34 as viewed from the rear. As shown in FIGS. 4 and 5, the inner surface of the ground terminal hole 12 b is provided with a restriction recess 12 d into which the locked protrusion 34 is engaged with the door 3 closed. When the main body portion 31 of the door body 3 receives a downward force in the closed position, the locked convex portion 34 abuts on the inner surface of the lower side of the restricting concave portion 12d, so that the lower side of the main body portion 31 with respect to the housing 1 is achieved. 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.

さらに、本体部３１の上端部において左右方向の中央部には、ガイド突起３６が後方へ突設されている。ガイド突起３６は、左右両端部が中央部よりも下方に突出したコ字形状に形成されている。ガイド突起３６が設けられていることにより、図８（ａ）に示すようにプラグＰの接続時には接地極の栓刃Ｐｃがガイド突起３６によってガイドされるから、図８（ｂ）に示すようにガイド突起３６を設けない場合に比べて接地極の栓刃Ｐｃが接地端子収納凹部１２の内面や接地端子２に引っかかりにくくなっている。また、ガイド突起３６により、扉体３の機械的強度が向上して破損が抑制されている。 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.

上記構成によれば、従来例のように下側の接地栓刃挿入口１０ｃを接地端子収納凹部１２の外側に設ける場合に比べ、接地端子２と接地栓刃挿入口１０ｃとの距離が小さくなるから小型化が可能となる。また、接地端子収納凹部１２と下側の接地栓刃挿入口１０ｃとを仕切る壁が存在しないことにより、プラグＰの挿抜の際に接地極の栓刃Ｐｃによるハウジング１の破損が発生しにくい。さらに、扉体３にガイド突起３６を設けたことにより、プラグＰの挿抜の際に接地極の栓刃Ｐｃが接地端子収納凹部１２の内面や接地端子２に引っかかりにくい。また、熱硬化性樹脂に比べて弾性に富む熱可塑性樹脂で扉体３を構成して扉体３の破損を抑制する一方、熱可塑性樹脂に比べて弾性が乏しいものの耐トラッキング性の高い熱硬化性樹脂でハウジング１を構成してトラッキングを抑制している。 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.

なお、扉体３の形状は本実施形態のものに限られず、例えば図９のように扉体３の本体部３１の切り欠き３１ｂの左右の寸法を接地栓刃挿入口１０ｃの左右の寸法と同程度としてもよい。この場合、栓刃挿入口１０ｃの開口縁の下部だけでなく左右も扉体３によって構成される。この構成を採用すれば、図１〜５の構成に比べて連結部３３の幅寸法を大きくとって扉体３の機械的強度を向上することができる。 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.

または、図１０〜図１２に示すように、切り欠き３１ｂを設ける代わりに、扉体３の本体部３１を略長方形状とし、下側の接地端子挿入口１０ｃに接続される栓刃が挿通される接地栓刃挿通穴３１ｃを扉体３の本体部３１に貫設してもよい。上記の例では、ガイド突起３６を接地栓刃挿通穴３１ｃの下側に設けている。この場合、ガイド突起３６に加えて接地栓刃挿通穴３１ｃの内面も請求項におけるガイド部となる。この構成を採用すれば、図９の場合よりもさらに連結部３３の幅寸法を大きくとって、さらに機械的強度を向上することができる。また、カバー１ｂの形状を図１１のようにして扉体３の形状を図３のようにする場合に比べ、扉体３が重ねられている分だけ下側の接地端子挿入口１０ｃの周縁部の機械的強度が向上している。 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.

また、結合凸部は、ハウジング１に対して着脱自在に結合して扉体３を閉位置に保持する作用があれば、上記実施形態のように係止によってハウジング１に保持される被係止凸部３４に限られず、例えば嵌合のような他の周知の手段によってハウジング１に結合するものであってもよい。 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.
