上述した電源プラグ装置においては、正しく端子７の凸部９、プラグ片１０の穴１１にセット（差し込まれた）された電源プラグは引き抜くときに強い力で引かなければ抜けない欠点があり、しっかり固定されたコンセントでは強い力で引き抜いたときに周辺の物に手をぶつけてしまう危険性がある。
また、テーブルタップにおいては簡易的にテープやマグネットで固定して使われる場合が多く、容易に引き抜けない欠点があった。さらに、電源プラグを容易に抜くためにテーブルタップやコンセント内部に装置や部品を配置するためコスト高となる欠点があった。
そこで、本発明の目的は、上述した実情を考慮して、テーブルタップやコンセントの狭い場所での配電による怪我防止、簡易固定されたテーブルタップやコンセントからの引き抜きを容易に行い、低コストで実現する電源プラグ装置を提供することにある。 In the power plug device described above, the power plug that is correctly set (inserted) in the convex portion 9 of the terminal 7 and the hole 11 of the plug piece 10 has a drawback that it cannot be pulled out unless it is pulled with a strong force. With a fixed outlet, there is a risk of hitting nearby objects when it is pulled out with a strong force.
In addition, the table tap is often used simply by being fixed with a tape or a magnet, and has a drawback that it cannot be pulled out easily. Furthermore, there is a disadvantage that the cost is increased because devices and parts are arranged inside the table tap and the outlet so that the power plug can be easily pulled out.
Therefore, the object of the present invention is realized at low cost by taking into consideration the above-mentioned situation, preventing injury due to power distribution in a narrow place of a table tap or outlet, and easily pulling out from a fixed table tap or outlet. An object of the present invention is to provide a power plug device.

図１は本発明による電源プラグ装置の全体構成を示す概略図である。図１において、電源プラグ装置Ａは、テーブルタップやコンセント等のプラグ受容体Ｂの下ケース１２の上カバー５の表面側３に電源プラグ１がコンセントやテーブルタップＢに接続された状態において電源プラグ１を一方向（矢印２方向）に傾けた状態で示されている。
図２は上カバー表面側のプラグ差し込み口の稜線に設けた面取り部分を示す概略断面図である。図２において、上カバー５の表面側３には一対のプラグ差し込み口５ａが所定の間隔をおいて平行に配置されており、各プラグ差し込み口５ａの一方の稜線（内壁）には斜めに傾斜した第１の面取り部分４を設けている。
この第１の面取り部分４と対角の上カバー５の内部側５’のプラグ差し込み口５ａの他方の稜線（内壁）には傾斜面状の第２の面取り部分６を設けている。つまり、差し込み口５ａは、対向する両内壁に面取り部分４、６を夫々備え、各面取り部分４、６は対称形状になっている。
また、下ケース１２の端子７の端部周辺８には電源プラグ１が一方に傾いたとき、プラグ片１０に他部品等が当たらないスペースを確保している。
図３は第２の面取り部分を覆う面取り部分被覆部材を説明するプラグ受容体をコンセントとして示す概略図である。図３において、上カバー５には、第２の面取り部分６を覆う第２の面取り部分被覆部材１３が内面側に配置され、この第２の面取り部分被覆部材１３には上カバー５の表面側に突出するレバー１４が摺動可能に配置されている。面取り部分被覆部材１３はコ字状の部材であり、プラグ１が傾倒した際にプラグ片１０の先端が変位する方向に配置されることにより、上カバー５の内側から第２の面取り部分６を覆うことができるように構成されている。また、面取り部分被覆部材１３は、上カバー５の下面に沿って一対の差し込み口５間を進退自在に構成されている。 FIG. 1 is a schematic diagram showing the overall configuration of a power plug device according to the present invention. In FIG. 1, the power plug device A is a power plug in a state where the power plug 1 is connected to the outlet or the table tap B on the surface side 3 of the upper cover 5 of the lower case 12 of the plug receiver B such as a table tap or an outlet. 1 is shown tilted in one direction (in the direction of arrow 2).
FIG. 2 is a schematic cross-sectional view showing a chamfered portion provided on the ridgeline of the plug insertion opening on the upper cover surface side. In FIG. 2, a pair of plug insertion holes 5a are arranged in parallel on the surface side 3 of the upper cover 5 at a predetermined interval, and one ridge line (inner wall) of each plug insertion hole 5a is inclined obliquely. The first chamfered portion 4 is provided.
An inclined second chamfered portion 6 is provided on the other ridge line (inner wall) of the plug insertion port 5 a on the inner side 5 ′ of the upper cover 5 diagonally opposite the first chamfered portion 4. That is, the insertion port 5a includes chamfered portions 4 and 6 on both inner walls facing each other, and the chamfered portions 4 and 6 are symmetrical.
Further, a space is secured around the end portion 8 of the terminal 7 of the lower case 12 so that when the power plug 1 is tilted to one side, the plug piece 10 does not hit other parts.
FIG. 3 is a schematic view showing a plug receiver as an outlet for explaining the chamfered portion covering member covering the second chamfered portion. In FIG. 3, a second chamfered portion covering member 13 that covers the second chamfered portion 6 is disposed on the inner surface side of the upper cover 5, and the second chamfered portion covering member 13 is on the surface side of the upper cover 5. A lever 14 protruding in the direction is slidably arranged. The chamfered portion covering member 13 is a U-shaped member, and is arranged in a direction in which the tip of the plug piece 10 is displaced when the plug 1 is tilted, so that the second chamfered portion 6 is formed from the inside of the upper cover 5. It is configured so that it can be covered. Further, the chamfered portion covering member 13 is configured to be movable back and forth between the pair of insertion openings 5 along the lower surface of the upper cover 5.

図４は第２の面取り部分を覆う部材が第２の面取り部分を開放している状態を示す概略図である。図３のプラグ片１０が傾いている状態では第２の面取り部分６は部材１３によって覆われていない。コ字状の面取り部分被覆部材１３は屈曲した両端部により各差し込み口５ａの面取り部分６を一括して開放したり覆うように構成されている。図４のように被覆部材１３が２つの差し込み口５ａの両面取り部分６を開放している状態では、プラグの抜き差しが自由となる。
図５は第２の面取り部分を覆う部材を説明するプラグ受容体をコンセントとして示す概略図である。図５において、プラグ片１０が傾いていない状態では第２の面取り部分被覆部材１３が第２の面取り部分６を覆っている。
図６は第２の面取り部分が面取り部分被覆部材によって覆われている状態を示す概略図である。図６において、第２の面取り部分６はレバー１４を操作して摺動させることによって第２の面取り部分被覆部材１３で覆われている。この場合は、プラグは不用意に脱落することが防止できる。
電源プラグ１を傾けることのできる空間へプラグ１を傾ける動作により端子７とプラグ片１０の圧着を解き、プラグ片１０が端子７に挟まれている摩擦力だけの抵抗で電源プラグ１を引き、この電源プラグ１を動かしながら抜く。この場合、電源プラグ１を傾ける方向は第１の面取り部分４の方向であって、且つテーブルタップやコンセントの中央方向とする。この時、プラグ片１０は被覆部材１３側へ傾く。
本発明によれば、プラグ片１０と端子７との係合を解くまでプラグ片１０を一方に傾けるために、上下ケース５、１２、端子７周辺において空間を得る。また、電源プラグ１を傾ける方向を示す表示をケースの表面に記載することで簡易固定などのテーブルタップにおいてテーブルタップのズレ、移動も防止できる。
面取り部分被覆部分１３のレバー１４の摺動によって第２の面取り部分６を覆うことでプラグ片１０が面取り部分被覆部材１３に当たり電源プラグ１は所定以上は傾かないために危険性なく、不慮の電源プラグ外れを防止できる。 FIG. 4 is a schematic view showing a state in which a member covering the second chamfered part opens the second chamfered part. When the plug piece 10 of FIG. 3 is inclined, the second chamfered portion 6 is not covered with the member 13. The U-shaped chamfered portion covering member 13 is configured to open or cover the chamfered portions 6 of the respective insertion openings 5a all together by bent both ends. In the state where the covering member 13 opens the double-sided portion 6 of the two insertion openings 5a as shown in FIG. 4, the plug can be inserted and removed freely.
FIG. 5 is a schematic view showing, as an outlet, a plug receiver for explaining a member covering the second chamfered portion. In FIG. 5, the second chamfered portion covering member 13 covers the second chamfered portion 6 when the plug piece 10 is not inclined.
FIG. 6 is a schematic view showing a state in which the second chamfered portion is covered with the chamfered portion covering member. In FIG. 6, the second chamfered portion 6 is covered with the second chamfered portion covering member 13 by operating the lever 14 to slide. In this case, the plug can be prevented from accidentally falling off.
The operation of tilting the plug 1 into the space where the power plug 1 can be tilted releases the crimping of the terminal 7 and the plug piece 10 and pulls the power plug 1 with a resistance of only the frictional force between which the plug piece 10 is sandwiched between the terminals 7, Remove the power plug 1 while moving it. In this case, the direction in which the power plug 1 is inclined is the direction of the first chamfered portion 4 and the center direction of the table tap or outlet. At this time, the plug piece 10 is inclined toward the covering member 13 side.
According to the present invention, a space is obtained around the upper and lower cases 5 and 12 and the terminal 7 in order to tilt the plug piece 10 to one side until the engagement between the plug piece 10 and the terminal 7 is released. In addition, the display indicating the direction in which the power plug 1 is tilted is described on the surface of the case, so that the table tap can be prevented from being displaced or moved in the table tap such as simple fixing.
By covering the second chamfered portion 6 by sliding the lever 14 of the chamfered portion covering portion 13, the plug piece 10 hits the chamfered portion covering member 13 and the power plug 1 does not tilt more than a predetermined amount. The plug can be prevented from coming off.
