Description

当発明は、電源をつなぐ配線用差込接続器のうち、導体となる平条状栓刃を２本持つプラグの差込を受ける２極コンセント（Ａタイプコンセントとも言う、以下Ａタイプコンセントという）に関するものであり、同じ２極プラグの挿入を受けるコネクタボディ、マルチダプ、テーブルタップなども含む。 The present invention is a two-pole outlet (also referred to as an A-type outlet, hereinafter referred to as an A-type outlet) that receives a plug having two flat strip-shaped blades that serve as conductors, among the plug-in connectors for wiring that connect the power supply. This includes connector bodies, multi-dups, table taps, etc. that receive the same two-pole plug.

従来の上記記載のＡタイプコンセントは主に次のような四つの欠点があった。
１、プラグをコンセントに差し込むときは、プラグ栓刃を挟持するコンセント端子の弾性圧力に抗して力を加えて押し込まなければならなかった。また、プラグをコンセントから引き抜くときも、プラグ栓刃がコンセント端子に挟持された状態から強引に引っ張り出すしかなかった。そのため握力の弱い人や、片手での扱いがしにくく、特に狭い場所での操作が不便で、プラグ首の電線が切れやすくなる誘因でもあった。
２、コンセント端子の挟持力が弱くなったりすることが原因で、プラグ栓刃とコンセント端子との接触不良状態や、プラグがコンセントに中途半端に差しこまれた状態になりやく、それがコンセントとプラグ栓刃の接触部位が発熱して火事や事故を引起こす原因の一つであった。
３、プラグを差し込むと同時に電源が接通されるため、電源を切断したいときはプラグをコンセントから引き抜くか、あるいはコンセントに別途切換スイチを設けなければならなかった。
４、コンセントを使用中に、プラグが何かに引っかかってコンセントから抜かれてしう、ドラブルを引き起こしやすい大きな欠点があった。
これらの問題点を解決するために、今までＡタイプコンセントの構造に関する技術思想が多く発表された。なかでコンセントの抜け止め機能を目的としたものは主に特開平１０−９２５１２、特開平２０００−７７１３７、特開平９−３２０６７１などが知られている。The conventional A-type outlet described above mainly has the following four drawbacks.
1. When inserting the plug into the outlet, it was necessary to push in against the elastic pressure of the outlet terminal holding the plug plug blade. Also, when pulling out the plug from the outlet, the plug plug blade must be pulled out of the outlet terminal. For this reason, it was difficult to handle with one hand or a person with weak grip strength, and it was inconvenient to operate in a particularly small space, and it was also an incentive to easily break the plug neck wire.
2. Due to the weakness of the outlet terminal clamping force, it is easy for the plug plug blade and the outlet terminal to be in poor contact, or the plug is halfway inserted into the outlet. This was one of the causes of fires and accidents due to heat generated at the plug plug blade contact area.
3. Since the power supply is connected as soon as the plug is inserted, when the power supply is to be cut off, the plug must be pulled out of the outlet or a separate switching switch must be provided in the outlet.
4. While using the outlet, there was a major drawback that caused the plug to get caught in something and unplugged from the outlet.
In order to solve these problems, many technical ideas related to the structure of the A-type outlet have been announced so far. Of these, Japanese Patent Laid-Open No. 10-92512, Japanese Patent Laid-Open No. 2000-77137, Japanese Patent Laid-Open No. 9-320671, etc. are mainly known for the purpose of preventing the outlet from coming off.

上記記載の先行技術の中で、特開平１０−９２５１２はコンセントの中にプラグ栓刃を両側から挟持する楕円形固定ローラを設け、楕円形ローラが９０度以上回転しないよう防止手段を設け、楕円形ローラが回転する際軸長による生じる圧力の変動を利用して抜け止め作用を図ったものであるが、ある程度抜けにくい効果はあるものの、抜けと止めにはならず、抜けにくくされた分挿入や脱出の際に力を加えなければならない。特開平２０００−７７１３７においては、コンセントの中にプラグ栓刃孔に挿入可能な抜け止めピンを設け、その抜け止めピンをプラグ栓刃孔に貫通させ、抜け止め作用を図ったもので、抜け止め状態の解除はコンセントの外部に別途スイチのような操作機関を設け、テコやクサビなどの部材でコンセントの中のピンを操作して解除するようにしたものであるが、コンセントの外部に別途抜け止め解除手段を設ける自体がよい発想とは思わないし、抜け止めピンをプラグ栓刃孔に貫通させる手段が、抜け止めピンの先端部分の僅かな太さの傾斜度により挿入されたプラグ栓刃の先端部を案内して行われるので、僅かな角度のずれや弾力の変化でも不具合が発生し易く、実用性が欠ける欠点がある。また、特開平９−３２０６７１においては、プラグ栓刃をコンセントに挿入して、横に回転させる際に、平面を呈するプラグ栓刃を弧状体に沿って回転させる際に生じる軌道角度差を利用して、半弧状の抜け止め部材をプラグ栓刃孔に差通して、抜け止め作用を図ったものであり、当技術は既に商品化され市販中であるが、プラグ栓刃孔に差通する抜け止め部材が半弧状の物であるため、完全に抜け止めにはならず、ある程度抜けにくくしたものに過ぎない。しかもプラグを差脱する回数が増すにつれ、阻止体部材の弾力が段々緩くなって役に立たなくなる場合が多い。何れにしても、今まで知られた技術の中では、上記で指摘した従来のコンセントの問題点をすべて解決したものはなかった。当発明の課題は、上記指摘した問題点を解決し、挿し抜きがし易く、プラグが中途半端な差込状態にならず、プラグをコンセントに差し入れた状態で電源の切換ができ、かつ作業中の不用意な脱落現象を犯さない真の抜き止めコンセントを提供することである。 Of the prior art described above, Japanese Patent Laid-Open No. 10-92512 provides an elliptical fixing roller that clamps the plug stopper blade from both sides in an outlet, and provides a means for preventing the elliptical roller from rotating more than 90 degrees. It is designed to prevent slipping by utilizing the pressure fluctuation caused by the shaft length when the roller is rotating. You must apply force when you escape. In Japanese Patent Application Laid-Open No. 2000-77137, a retaining pin that can be inserted into a plug plug blade hole is provided in an outlet, and the retaining pin is passed through the plug plug blade hole to achieve a retaining function. To release the state, an operation engine such as a switch is provided outside the outlet, and the pin inside the outlet is operated with a lever or wedge to release it. It seems that it is not a good idea to provide the stopper release means itself, and the means for penetrating the retaining pin through the plug stopper blade hole is a plug stopper blade inserted by the slight inclination of the tip of the retaining pin. Since it is performed by guiding the tip portion, there is a drawback that a defect is likely to occur even if a slight angle shift or elasticity change, and practicality is lacking. Further, in Japanese Patent Laid-Open No. 9-320671, when the plug plug blade is inserted into the outlet and rotated sideways, the trajectory angle difference generated when the plug plug blade having a flat surface is rotated along the arcuate body is used. The semi-arc-shaped retaining member is inserted into the plug stopper blade hole to prevent the stopper, and this technology has already been commercialized and is commercially available. Since the stopper member is a semi-arc-shaped object, it is not completely prevented from coming off, but is merely a member that is difficult to come off to some extent. In addition, as the number of times the plug is inserted and removed increases, the resilience of the blocking member becomes loose gradually and often becomes useless. In any case, none of the known techniques has solved all the problems of the conventional outlets pointed out above. The problem of the present invention is to solve the above-mentioned problems, easy to insert and remove, the plug is not halfway inserted, the power can be switched with the plug inserted into the outlet, and the work is in progress It is to provide a true outlet that does not cause the inadvertent dropout phenomenon.

Ａタイププラグは導体となる２本の平行した平条状栓刃を持ち、栓刃の先端には丸い孔が設けられてある。当発明はＡタイププラグのこの形状上の特徴を利用して、２本のプラグ栓刃の差込を受けるコンセントに、従来のコンセントと同じく、銅などの弾性を持つ導体でプラグ栓刃を挟持、又は接触させ、電源の接通役割を果たせると同時に、プラグ栓刃の先端部分に設けられた丸い栓刃孔に円柱形突出物から形成された阻止体を挿通させ、完全な抜きとめ役を果させる。さらにこれらの機能を合理的な構造により、ワンタッチ操作を実現するために、次の技術を利用した。 The A-type plug has two parallel flat-shaped plug blades serving as conductors, and a round hole is provided at the tip of the plug blade. The present invention uses this shape feature of the A-type plug to hold the plug plug blade with an elastic conductor such as copper in the outlet receiving the insertion of the two plug plug blades as in the conventional outlet. In addition, it is possible to play a role of connecting the power supply, and at the same time, a blocking member formed from a cylindrical protrusion is inserted into the round plug blade hole provided at the tip of the plug plug blade, so that it can be completely removed. Let it finish. Furthermore, the following technology was used to realize one-touch operation with a rational structure for these functions.

円心の位置が変動されれば、その円心を中心として回転する物体の回転軌道も相応に変動されると言う自然原理を応用して、プラグ栓刃をコンセントに挿入して右又は左に所定の円心と軌道で約９０度回動可能にし、それと同時にプラグ栓刃孔に挿通可能な阻止体をプラグと異なる円心と軌道で回転させ、プラグと阻止体の回転軌道が重合されたり分離されたりする軌道差を利用して、プラグをコンセントに差入する時と引き抜く時は円柱形突出物がプラグ栓刃差入孔から離れ、プラグ栓刃が解放された状態におかれ挿し抜きがし易く、プラグ栓刃を横に回転させるにつれ、上記阻止体も回転されながらプラグ栓刃と阻止体の両軌道の距離が段々接近され、プラグ栓刃と阻止体が略９０度回転された時は、プラグ栓刃がコンセント端子と接触され、電源が接通されると同時に、上記両軌道が重合され阻止体がプラグ栓刃孔に挿通され、プラグが抜け止め状態となり、プラグをコンセントの挿入位置にまわし戻すと、プラグ栓刃がコンセント端子から脱離され、電源が切断されると同時に、阻止体も回転しながらプラグ栓刃孔から抜かれ、プラグが解放状態に戻るようにする。そしてこれらの動きがすべてプラグをコンセントに差し入れて横に回すだけのワンタッチ操作で同時に行うようにする。
当発明は以上の技術思想により実現し、それにより次のような効果を現す。Applying the natural principle that if the position of the circle center is changed, the rotation trajectory of the object rotating around the circle center is also changed accordingly, the plug plug blade is inserted into the outlet and turned right or left. It is possible to rotate about 90 degrees with a predetermined circle center and track, and at the same time, the blocking body that can be inserted into the plug plug blade hole is rotated with a circle center and track different from the plug, and the rotation track of the plug and blocking body is superposed. When the plug is inserted into the outlet or pulled out by using the difference in the orbit, which is separated, the cylindrical protrusion is separated from the plug plug blade insertion hole, and the plug plug blade is released and inserted. As the plug stopper blade is rotated sideways, the distance between both the plug stopper blade and the blocking member is gradually approached while the blocking member is rotated, and the plug stopper blade and the blocking member are rotated approximately 90 degrees. When the plug plug blade contacts the outlet terminal At the same time as the power supply is connected, both the above tracks are superposed, the blocking body is inserted into the plug plug blade hole, the plug is prevented from coming off, and when the plug is turned back to the insertion position of the outlet, the plug plug blade is At the same time as the power supply is cut off from the outlet terminal, the blocking body is pulled out from the plug plug blade hole while rotating so that the plug returns to the released state. All of these movements are performed simultaneously with a one-touch operation by simply inserting the plug into the outlet and turning it sideways.
The present invention is realized by the above technical idea, and thereby exhibits the following effects.

（イ）２本のプラグ栓刃をコンセントのプラグ栓刃差入孔に差入すると、プラグ栓刃の先端がコンセント基板に接するまで、通過する場所はすべて空間になってあるので、圧力を加える必要がなく、簡単に差し入れることができる。また、プラグを抜くときは、電源がつながった状態からプラグを挿入するときの位置までまわし戻すと、プラグがコンセントに差入されたときと同じ開放された状態に戻るので、力を入れずに引き抜くことができる。プラグを横に回す動きは、プラグを押し入れたり、引っ張ったりする時の腕全体の動きとは違い、手首だけを動いてプラグを回せれば良いので、ドアの鍵を閉める動きと同様にとっても簡単でやさしい動きになる。
（ロ）プラグをコンセントに差し入れて横に略９０度まわすと、２本のプラグ栓刃がコンセント端子と接触され電源がつながると同時に、阻止体がプラグ栓刃孔に挿通される。すると阻止体が球状ではなく円柱形であることと、円柱形物体がプラグ栓刃孔に完全に挿通されるため、プラグが完全にロックされるので、抜けにくくした抜けとめコンセントとは違い、コンセントが破壊されない限り電源がつながった状態でプラグが中途半端な状態になることも、作業中に何かに引かれて抜けてしまう可能性もなくなる。
（ハ）プラグをコンセントに差込むと同時に電源がつながり、電源を切断したいときはプラグをコンセントから引き抜くしかなかったため、メンドなときは電源を使わないときも電源を繋いたまま放置した場合がおおかった今までのコンセントに比べ、当発明はプラグをコンセントに差入れたままの状態で、電源を接通した工作状態と、切断した休止状態と二つの状態を切換しながら使うことができるので、電源を使わない時は休止状態にすることで安全かつ節電になる。そしてコンセントのカバーの表面にプラグの挿入位置と回転後の位置に合わせて文字や矢印で、簡単にコンセントの電源接通状態を表示することが可能である。
（ニ）当発明は上記記載のような新しい機能を備えたコンセントであるが、当発明と同一発明者が出願した壁内設置型コンセントボックス（特開２００５−２４５１８７）と結合することで、より優れた機能を発揮することが出来る。特開２００５−２４５１８７は壁内に設置して使用するコンセントボックスに関するもので、コンセントを壁内の上、下、左、右の面に設置可能なことと、一つのコンセントを壁の両側から使えることを特徴としたものであるが、コンセントボックスの中に当発明品のコンセントを取り付けることで、今まで下向きと横向きにしか設置できながったコンセントを天井などに上向きに設置するなど、如何なる方向や角度で設置することが可能となるし、コンセントボックスをよりコンパックトにすることができるなどの利点がある。(B) When two plug plug blades are inserted into the plug plug blade insertion hole of the outlet, the place where the plug passes through is a space until the tip of the plug plug blade comes into contact with the outlet board, so apply pressure. It is not necessary and can be easily inserted. Also, when unplugging the plug, turn it back to the position where the plug was inserted from the power-on state, and the plug will return to the same open state as when it was inserted into the outlet. Can be pulled out. The movement of turning the plug sideways is different from the movement of the whole arm when pushing in or pulling the plug, it is only necessary to move the wrist by turning the plug, so it is as easy as the movement of closing the door lock It becomes a gentle movement.
(B) When the plug is inserted into the outlet and turned sideways by approximately 90 degrees, the two plug plug blades are brought into contact with the outlet terminal to connect the power source, and at the same time, the blocking body is inserted into the plug plug blade hole. Then, since the blocking body is not spherical but cylindrical, and the cylindrical object is completely inserted into the plug plug blade hole, the plug is completely locked, so unlike the unplugged outlet that is difficult to remove, the outlet As long as the plug is not destroyed, there is no possibility that the plug will be in a halfway state when the power is connected, or that it will be pulled out by something during the work.
(C) When the plug is plugged into the outlet, the power is turned on at the same time. When you want to turn off the power, the plug must be pulled out of the outlet. Compared to conventional outlets, the present invention can be used while switching between two working states, a working state with the power supply connected and a disconnected state, with the plug inserted into the outlet. When not in use, it is safe and saves energy by putting it in hibernation. Then, it is possible to easily display the power connection state of the outlet with letters and arrows according to the plug insertion position and the rotated position on the surface of the outlet cover.
(D) Although the present invention is an outlet having the above-mentioned new functions, it can be further combined with a wall-mounted outlet box (JP 2005-245187) filed by the same inventor as the present invention. Excellent function can be demonstrated. Japanese Patent Laid-Open No. 2005-245187 relates to an outlet box that is installed in a wall and used. The outlet can be installed on the upper, lower, left, and right surfaces of the wall, and one outlet can be used from both sides of the wall. However, by installing the outlet of the product of the present invention in the outlet box, the outlet that could only be installed downward and sideways until now is installed upwards on the ceiling etc. There are advantages in that it can be installed in any direction and angle, and the outlet box can be made more compact.

以下、上記技術思想の実施形態に置いて実施例を通して、図面を参照しながら詳細に説明する。まず、図７の分解斜視図に基ついてコンセントの下から上の順に実施例１の構造及び機能を説明する。 Hereinafter, the embodiment of the above technical idea will be described in detail with reference to the drawings through examples. First, the structure and function of the first embodiment will be described in the order from the bottom to the top of the outlet based on the exploded perspective view of FIG.

コンセントの最底層は基板１３から形成し、基板１３の中心に中心軸２１を垂直に設け、中心軸２１を後述の中心幹３１と連動させることで、プラグ１を中心軸２１を円心として回転するようにし、中心軸２１とは異なる円心で、基板１３の周壁を上方に突出させて形成した円形の回動枠軌道穴９を設け、それによって基板１３の断面は凹形を呈し、基板１３の両辺縁にはカバーを嵌入させるための溝３２が設けてある。（図７参照） The bottom layer of the outlet is formed of the substrate 13, the central axis 21 is provided vertically at the center of the substrate 13, and the central axis 21 is interlocked with a central trunk 31 to be described later, so that the plug 1 is rotated around the central axis 21. The circular rotation frame track hole 9 formed by projecting the peripheral wall of the substrate 13 upward with a circular center different from the central axis 21 is provided, whereby the cross section of the substrate 13 has a concave shape. Grooves 32 for fitting the cover are provided on both sides of 13. (See Figure 7)

そして、回動枠軌道穴９の中に回動枠４を嵌入させるが、回動枠４は略長方形枠の両端に、プラグ栓刃２ａ、２ｂを挿入可能な幅と、少なくともプラグ栓刃の厚さの二倍の四角形貫通空間５ａ、５ｂを設けるが、貫通空間５ａ、５ｂは中の半分はプラグ栓刃２ａ、２ｂを差通できるように貫通された空間であって、その空間と隣接した残った半分の空間は中心部に円柱形突出部６ａ、６ｂが両方同じ方向を向いて突設されてあり、突出部の長さは、少なくともプラグ栓刃２ａ、２ｂの厚さと同じく、完全にプラグ栓刃を貫通可能に突出されてある。（図７、図８参照） Then, the rotation frame 4 is inserted into the rotation frame track hole 9, and the rotation frame 4 has a width at which the plug stopper blades 2a and 2b can be inserted at both ends of the substantially rectangular frame, and at least the plug stopper blade. Square through spaces 5a and 5b having twice the thickness are provided. The through spaces 5a and 5b are spaces that are penetrated so that the plug plug blades 2a and 2b can be inserted, and adjacent to the spaces. In the remaining half space, the cylindrical protrusions 6a and 6b are provided in the center so as to protrude in the same direction, and the length of the protrusion is the same as at least the thickness of the plug stopper blades 2a and 2b. Is projected so as to be able to penetrate the plug plug blade. (See Figs. 7 and 8)

そして、回動枠４の中心部には略長方形を呈する移動中心孔７を貫設するが、移動中心孔７には後述の中心幹３１に設けられた突出部２３が、中で所望の位置まで自在に前後スライド可能な幅と長さに設け、回動枠４の両端の外側表面は回動枠軌道穴９のなかで潤滑に回転させるため弧形を形成し、回動枠４の高さは、回動枠４を回動枠軌道穴９の中に嵌入した状態で、プラグ栓刃２ａ、２ｂを差し入れたとき、円柱形突出部６ａ、６ｂとプラグ栓刃孔３ａ、３ｂの高さとが一致するようになってある。（図７、図８参照） The central portion of the rotation frame 4 is provided with a movement center hole 7 having a substantially rectangular shape. The movement center hole 7 has a protrusion 23 provided on a center trunk 31 (described later) at a desired position. The outer surface of the both ends of the rotating frame 4 is formed in an arc shape so as to lubricately rotate in the rotating frame track hole 9, and the height of the rotating frame 4 is increased. When the plug stopper blades 2a and 2b are inserted in a state where the rotation frame 4 is fitted into the rotation frame track hole 9, the heights of the cylindrical protrusions 6a and 6b and the plug stopper blade holes 3a and 3b are increased. And come to match. (See Figs. 7 and 8)

回動枠軌道穴９の中に回動枠４を嵌入させた基板１３の上に、隔離板１５を載設する。隔離板１５には中心部に上記記載の突出部２３を通過させるための長方形中心孔１８と、長方形中心孔１８の中心点を円心として約９０度回転させた半円形を呈するプラグ栓刃軌道孔１７ａ、１７ｂを対向して貫設されており、隔離板１５の上のプラグ栓刃２ａ、２ｂが約９０度回転された時のプラグ栓刃軌道孔１７ａ、１７ｂの両側に電線と連接されたコンセント端子１６ａ、１６ｂを架設し、コンセント端子１６ａ、１６ｂはそれぞれがプラグ栓刃２ａ、２ｂを両側から挟持するよう弾性挟持片から形成する。（図７参照） The separator 15 is placed on the substrate 13 in which the rotation frame 4 is fitted in the rotation frame track hole 9. The separator plate 15 has a rectangular center hole 18 through which the projection 23 described above is passed at the center, and a plug stopper blade track having a semicircular shape rotated about 90 degrees around the center point of the rectangular center hole 18 as a center. The holes 17a and 17b are formed so as to face each other, and are connected to electric wires on both sides of the plug plug blade raceways 17a and 17b when the plug plug blades 2a and 2b on the separator plate 15 are rotated about 90 degrees. The outlet terminals 16a and 16b are constructed, and the outlet terminals 16a and 16b are formed of elastic clamping pieces so that the plug plug blades 2a and 2b are clamped from both sides. (See Figure 7)

そして、コンセント端子１６ａ、１６ｂの上方に回動天井板１９を設けるが、回動天井板１９は円形板から形成し、円形板の上にプラグ栓刃２ａ、２ｂを垂直に挿入可能なプラグ栓刃差入孔２０ａ、２０ｂと円形板の周辺に辺縁３０を突設させる。そして円形板の裏面の中心部から下方に向けて垂直に伸びて形成された中心幹３１が設けられてあり、中心幹３１の下端部には略立方体の突出部２３を設け、中心幹３１と突出部２３は中空状にし、中心軸２１を突出部２３と中心幹３１に嵌入させることで、回動天井板１９の裏面はコンセント端子１６ａ、１６ｂに当たらない高さで、中心軸２１を円心として回転自在になる。また、略立方体の突出部２３は上記隔離板１５に設けられた長方形中心孔１８を通過して、上記回動枠４に貫設された移動中心孔７の中で前後スライド可能に嵌入される。（図７参照） A rotary ceiling plate 19 is provided above the outlet terminals 16a and 16b. The rotary ceiling plate 19 is formed of a circular plate, and plug plug blades 2a and 2b can be vertically inserted on the circular plate. Edges 30 are projected from the blade insertion holes 20a, 20b and the periphery of the circular plate. A central trunk 31 is formed to extend vertically downward from the center of the back surface of the circular plate. A substantially cubic protrusion 23 is provided at the lower end of the central trunk 31. The projecting portion 23 is hollow, and the center shaft 21 is fitted into the projecting portion 23 and the center trunk 31, so that the back surface of the rotating ceiling plate 19 is at a height that does not hit the outlet terminals 16a and 16b, and the center shaft 21 is circular. It becomes free to rotate as a heart. Further, the substantially cubic protrusion 23 passes through a rectangular center hole 18 provided in the separator 15 and is slidably inserted in the moving center hole 7 penetrating the rotating frame 4. . (See Figure 7)

そして最上層は回動天井板１９の上に、カバー２９を被せるのだが、カバー２９には回動天井板嵌合口２２が設けられてあり、カバーの表面には回動天井板１９に設けられたプラグ栓刃差入孔２０ａ、２０ｂのプラグ挿入位置と回転後の電源接通位置と一致する場所に、異色で矢印や文字などで電源の接通状態や回転方向などを示す。（図７参照） The uppermost layer covers the revolving ceiling plate 19 with a cover 29. The cover 29 is provided with a revolving ceiling plate fitting port 22, and the surface of the cover is provided on the revolving ceiling plate 19. In the plug plug blade insertion holes 20a and 20b, the power supply connection state, the rotation direction, etc. are indicated by arrows and characters in different colors at positions where the plug insertion positions of the plug plug blade insertion holes 20a and 20b coincide with the rotated power supply connection positions. (See Figure 7)

当実施例は以上の構造で形成されており、これを使用する際は、プラグ１を片手で持って、プラグ栓刃２ａ、２ｂを回動天井板１９に設けられたプラグ栓刃差入孔２０ａ、２０ｂに差入する。するとプラグ栓刃２ａ、２ｂはプラグ栓刃差入孔２０ａ、２０ｂと隔離板１５に設けられたプラグ栓刃軌道孔１７ａ、１７ｂを通過して、回動枠４に設けられた貫通空間５ａ、５ｂに入り、先端部分はコンセント基板１３に接触する。それまでプラグ栓刃が通る場所はすべて空間になってあるため、圧力を加える必要がなく、簡単に差込することができる。（図４参照） The present embodiment is formed with the above structure, and when this is used, the plug 1 is held with one hand, and the plug plug blades 2a and 2b are provided on the rotary ceiling plate 19 with plug plug blade insertion holes.

Then, the plug plug blades 2a and 2b pass through the plug plug blade insertion holes 20a and 20b and the plug plug blade raceway holes 17a and 17b provided in the separating plate 15, and pass through the space 5a provided in the rotary frame 4. 5b, and the tip portion contacts the outlet board 13. Until then, the place where the plug plug blade passes is all space, so it is not necessary to apply pressure and can be easily inserted. (See Figure 4)

プラグ１をコンセントに差入したら、そのままプラグ１を時計方向に約９０度回転させる。するとプラグ１は中心幹３１を中心点として回動天井板１９と一緒に回転されるのだが、プラグ栓刃２ａ、２ｂは、中心軸２１に嵌合された中心幹３１の固定作用と、カバー２９に設けられた回動天井板嵌合口２２の回動天井板１９に対しての軌道安定作用と、そして隔離板１５に設けたプラグ栓刃軌道孔１７ａ、１７ｂのプラグ栓刃に対しての控制作用などで、プラグ栓刃２ａ、２ｂは所定の軌道から離れることなく、精確な軌道で回転することになる。（図１参照） When the plug 1 is inserted into the outlet, the plug 1 is rotated about 90 degrees clockwise. Then, the plug 1 is rotated together with the rotating ceiling plate 19 with the central trunk 31 as the central point, but the plug plug blades 2a and 2b are fixed to the central trunk 31 fitted to the central shaft 21 and covered. 29, the track stabilizing action of the rotary ceiling plate fitting port 22 provided on the rotary plate 19 on the rotary ceiling plate 19 and the plug plug blades of the plug plug blade track holes 17a and 17b provided on the separator plate 15. The plug plug blades 2a and 2b are rotated in an accurate path without leaving a predetermined path for making a copy. (See Figure 1)

そしてプラグ栓刃２ａ、２ｂが約９０度回転されると、隔離板１５の上の部分のプラグ栓刃２ａ、２ｂはプラグ栓刃軌道孔１７ａ、１７ｂの両側に架設されたコンセント端子１６ａ、１６ｂの間にそれぞれ挟持され電源が接通される。（図６参照） When the plug plug blades 2a and 2b are rotated by about 90 degrees, the plug plug blades 2a and 2b on the upper part of the separator plate 15 are connected to outlet terminals 16a and 16b installed on both sides of the plug plug blade track holes 17a and 17b. And the power source is connected. (See Figure 6)

一方、隔離板１５の下の部分に配置された回動枠４は、貫通空間５ａ、５ｂに挿入されたプラグ栓刃２ａ、２ｂの回動枠４の側壁に対しての推動作用と、中心幹３１の下端に設けた突出部２３の中心孔７に対しての連動作用で、回動枠４はプラグ栓刃２ａ、２ｂと同時に同歩回転を始める。（図１参照） On the other hand, the rotating frame 4 arranged in the lower part of the separator 15 is used for thrusting the plug stopper blades 2a and 2b inserted into the through spaces 5a and 5b with respect to the side wall of the rotating frame 4, and the center. Due to the interlocking action of the projecting portion 23 provided at the lower end of the trunk 31 with respect to the center hole 7, the rotating frame 4 starts rotating at the same time as the plug blades 2 a and 2 b. (See Figure 1)

しかし、回動枠４はプラグ栓刃２ａ、２ｂと同時に回転しながらも、基板１３に設けられた回動枠軌道穴９に制限された軌道を沿って回転されるのだが、回動枠軌道穴９の回転軌道とプラグ栓刃２ａ、２ｂの軌道がつれてある為、回動枠４は中心孔７の中で中心幹３１の下端に設けられた突出部２３との滑動で、回転しながら中心点が移動され、当初は貫通空間５ａ、５ｂの中の貫通された半分の空間で収納されていたプラグ栓刃２ａ、２ｂが、プラグ１が略９０度回転された時点では、上記両軌道が重合され、貫通空間５ａ、５ｂの中の隣の半分の空間に移動され、その空間の中に突設された円柱形突出部６ａ、６ｂがそれぞれプラグ栓刃孔３ａ、３ｂに挿通されるようになる。（図１参照） However, while the rotating frame 4 rotates simultaneously with the plug plug blades 2a and 2b, the rotating frame 4 is rotated along a track limited by the rotating frame track hole 9 provided in the substrate 13, but the rotating frame track. Since the rotation track of the hole 9 and the track of the plug plug blades 2a and 2b are connected, the rotation frame 4 rotates by sliding with the protrusion 23 provided at the lower end of the center trunk 31 in the center hole 7. However, when the plug plug blades 2a and 2b initially housed in the half-penetrated spaces in the penetrating spaces 5a and 5b are rotated by approximately 90 degrees, the center point is moved. The track is overlapped and moved to the adjacent half space in the through spaces 5a and 5b, and the cylindrical protrusions 6a and 6b projecting into the spaces are inserted into the plug plug blade holes 3a and 3b, respectively. Become so. (See Figure 1)

円柱形突出部６ａ、６ｂがプラグ栓刃孔３ａ、３ｂに挿通されると、突出部の形状が球状ではなく円柱形であるため、プラグ栓刃との接触面積が一点ではなく弧状の一面になるため、プラグ栓刃２ａ、２ｂを完全にロックされてしまう。そして、回動枠４の上には隔離板１５が載設固定されたため、そのままではプラグを引きぬくことができなくなる。（図１、図６参照） When the cylindrical protrusions 6a and 6b are inserted into the plug plug blade holes 3a and 3b, the shape of the protrusion is not spherical but cylindrical, so that the contact area with the plug plug blade is not a single point but an arc-shaped surface. Therefore, the plug plug blades 2a and 2b are completely locked. Since the separator 15 is placed and fixed on the rotating frame 4, the plug cannot be pulled out as it is. (See Figs. 1 and 6)

プラグ１をコンセントから抜くときは、まずプラグ１を電源が接通された状態から差入するときと反対方向に、つまり反時計方向に略９０度回し戻す。すると隔離板１５の上の部分のプラグ栓刃２ａ、２ｂはコンセント端子１６ａ、１６ｂに挟持された状態から脱離されると同時に電源が切断される。そして隔離板１５の下のプラグ栓刃２ａ、２ｂは差入するときと相反の作用で、回動枠４と同時に回転を始め、プラグ栓刃２ａ、２ｂが元の挿入位置に巻き戻されたときは、プラグ栓刃２ａ、２ｂと回動枠４との軌道差で、円柱形突出部６ａ、６ｂもプラグ栓刃孔３ａ、３ｂから完全に脱離され、プラグ１は解放された状態に戻るので軽く引き出せるようになる。 When unplugging the plug 1 from the outlet, first, the plug 1 is turned back approximately 90 degrees in the opposite direction to that when the power supply is connected, that is, counterclockwise. Then, the plug plug blades 2a and 2b above the separator 15 are detached from the state of being sandwiched between the outlet terminals 16a and 16b, and at the same time, the power is turned off. Then, the plug plug blades 2a and 2b below the separator plate 15 are rotated at the same time as the rotation frame 4 due to the opposite action of insertion, and the plug plug blades 2a and 2b are rewound to the original insertion positions. When the plug plug blades 2a, 2b and the rotary frame 4 are trajectory difference, the cylindrical protrusions 6a, 6b are also completely detached from the plug plug blade holes 3a, 3b, and the plug 1 is released. Because it returns, it can be pulled out lightly.

プラグ１を挿脱可能な位置に戻してからは、必要によってプラグをコンセントから抜き出すこともできるし、次回使用するとき電源を簡単に接通させるため、抜かずに、コンセントに挿入されたまま状態にしておいても、電源が切断されているため、安全かつ節電にもなる。 After returning the plug 1 to the position where it can be inserted / removed, the plug can be removed from the outlet if necessary, and it can be easily connected to the power supply the next time it is used. However, since the power supply is cut off, it is safe and power saving.

そして、コンセントにプラグが挿入されていない時は、回動枠４の外側面と回動枠軌道穴９の内壁との適度の摩擦力と、中心幹３１の下端部に設けられた突出部２３の移動中心孔７に対しての係止作用で、回動枠４が勝手に回転され、プラグ挿入位置が移動されるようなことは起きない。 When the plug is not inserted into the outlet, an appropriate frictional force between the outer surface of the rotating frame 4 and the inner wall of the rotating frame track hole 9 and the protrusion 23 provided at the lower end of the center trunk 31 are provided. Due to the locking action with respect to the movement center hole 7, the rotating frame 4 is not rotated freely and the plug insertion position is not moved.

当実施例では、抜け止め部分の円柱形突出部６ａ、６ｂを一つの回動枠４の両端に設け、それを一つの丸い回動枠軌道穴９の中で回動させた前記実施例１の構造とは違い、抜け止め部分の円柱形突出部６ａ、６ｂを二つの単体回動枠８ａ、８ｂに別々に設け、回動軌道を制限する回動軌道穴もそれに相応した二つの半円形単体回動枠軌道穴３６ａ、３６ｂを対向して別々に設け、その中に単体回動枠８ａ、８ｂをそれぞれ嵌入させたもので、単体回動枠軌道穴３６ａ、３６ｂの回動軌道は上記回動枠軌道穴９と同じ軌道にしたものである。（図９参照） In the present embodiment, the cylindrical protrusions 6a and 6b of the retaining portion are provided at both ends of one rotating frame 4 and rotated in one round rotating frame track hole 9 in the first embodiment. Unlike the above structure, the cylindrical protrusions 6a and 6b of the retaining portion are separately provided on the two single rotating frames 8a and 8b, and the rotating track holes for limiting the rotating track are also two semicircular shapes corresponding thereto. The single rotation frame track holes 36a and 36b are provided separately and opposed to each other, and the single rotation frame track holes 8a and 8b are respectively inserted therein. The rotation tracks of the single rotation frame track holes 36a and 36b are as described above. This is the same track as the rotation frame track hole 9. (See Figure 9)

それに従って、中心幹３１の下端に設けた突出部２３をなくし、隔離板１５の上の四角形中心孔１８は変りに円形中心孔２７を設ける。 Accordingly, the protrusion 23 provided at the lower end of the center trunk 31 is eliminated, and the square center hole 18 on the separator plate 15 is provided with a circular center hole 27 instead.

そして、コンセントにプラグが挿入されていない時、単体回動枠８ａ、８ｂが勝手に回転され、プラグ差入口が移動されることのないようにするために、単体回動枠軌道穴３６ａ、３６ｂの中に常時単体回動枠８ａ、８ｂを電源切断位置に付勢させるよう弾性体１１ａ、１１ｂを設ける。それ以外の構造は前記実施例１と同様である。（図９参照） When the plug is not inserted into the outlet, the single rotation frames 8a and 8b are rotated freely, and the single rotation frame track holes 36a and 36b are prevented from being moved. The elastic bodies 11a and 11b are provided so as to constantly urge the single rotating frames 8a and 8b to the power cut position. Other structures are the same as those in the first embodiment. (See Figure 9)

この実施例を使用するときは、プラグ栓刃２ａ、２ｂをコンセントに差入すると、プラグ栓刃２ａ、２ｂは上記実施例１と同じ解放された位置に置かれる。そして、プラグ１を時計方向に横に回転させると、プラグ栓刃２ａ、２ｂの側面が単体回動枠８ａ、８ｂの側壁に対しての推圧作用で、単体回動枠８ａ、８ｂがプラグと一緒に回転し、単体回動枠８ａ、８ｂは単体回動枠軌道穴３６ａ、３６ｂの軌道に沿って回転するため、プラグが約９０度回転された時は、最初５ａ、５ｂの中の貫通空間に収容されていたプラグ栓刃２ａ、２ｂは、その隣の空間に移され、その空間に突設された円柱形突出部６ａ、６ｂがそれぞれプラグ栓刃孔３ａ、３ｂに挿通されるようになる。そして電源の切断操作や、プラグの抜く操作などは、実施例１と同じ操作をすることで、同じ原理により同じ効果を得られる。（図１、図９参照） When this embodiment is used, when the plug plug blades 2a and 2b are inserted into the outlets, the plug plug blades 2a and 2b are placed in the same released position as in the first embodiment. When the plug 1 is rotated sideways in the clockwise direction, the side surfaces of the plug plug blades 2a and 2b are thrusted against the side walls of the single rotation frames 8a and 8b, and the single rotation frames 8a and 8b are plugged. Since the single rotation frames 8a and 8b rotate along the tracks of the single rotation frame track holes 36a and 36b, when the plug is rotated about 90 degrees, the first rotation frames 8a and 8b The plug plug blades 2a and 2b accommodated in the through space are moved to the adjacent space, and the columnar protrusions 6a and 6b projecting from the space are inserted into the plug plug blade holes 3a and 3b, respectively. It becomes like this. Further, the same effect can be obtained from the same principle by performing the same operations as those in the first embodiment, such as the power-off operation and the plug removal operation. (See Fig. 1 and Fig. 9)

当実施例では、抜け止め部分の円柱形突出部を回動枠の中に設け、回動枠を回転させて抜け止め役の円柱形突出部をプラグ栓刃孔に挿通させた上記実施例１と実施例２の方法とは違い、円柱形突出部代わりに長い棒状から形成された円柱形回動棒１４ａ、１４ｂを、基板１３の中心から離れた左右両側を支点として各自回略９０度回動自在に設け、プラグ栓刃２ａ、２ｂと異なる円心と軌道で回動させたものである。それによりプラグ栓刃２ａ、２ｂが差し抜き位置に置かれたときは、プラグ栓刃２ａ、２ｂが円柱形回動棒１４ａ、１４ｂと離れ、解放された状態に置かれるが、プラグ１を略９０度回転させた時は、円柱形回動棒１４ａ、１４ｂも同歩回転された先端部分がそれぞれプラグ栓刃孔３ａ、３ｂに挿通され、プラグを完全にロックさせるようになる。（図１０、図１１、図１２、図１３参照） In this embodiment, the columnar protruding portion of the retaining portion is provided in the rotating frame, and the rotating frame is rotated so that the columnar protruding portion serving as a retaining portion is inserted into the plug plug blade hole. Unlike the method of the second embodiment, the cylindrical rotating rods 14a and 14b formed in the shape of long rods instead of the cylindrical protrusions are rotated approximately 90 degrees each around the left and right sides away from the center of the substrate 13 as fulcrums. It is provided so as to be movable, and is rotated around a circular center and orbit different from the plug plug blades 2a and 2b. As a result, when the plug plug blades 2a and 2b are placed in the insertion / removal position, the plug plug blades 2a and 2b are separated from the cylindrical rotary rods 14a and 14b and placed in a released state. When rotated 90 degrees, the cylindrical rotating rods 14a and 14b are also inserted into the plug plug blade holes 3a and 3b, respectively, so that the plugs are completely locked. (See FIGS. 10, 11, 12, and 13)

そして、円柱形回動棒１４ａ、１４ｂをプラグ栓刃２ａ、２ｂの回転に同歩回転させるため、基板１３に中心軸２１を円心とした回動枠軌道穴３３を基板１３の周壁を突出させて設け、その回動枠軌道穴３３の中に回転可能な円形回動枠３５を設け、円形回動枠３５の中にプラグ栓刃２ａ、２ｂを収容するためのプラグ栓刃差入口１０ａ、１０ｂを貫通させ、周囲の壁には円柱形回動棒１４ａ、１４ｂの動きをコントロルするための突出壁２８ａ、２８ｂと突出壁３８ａ、３８ｂを設ける。（図１０参照） Then, in order to rotate the column-shaped rotating rods 14a and 14b in the same step as the rotation of the plug plug blades 2a and 2b, a rotating frame track hole 33 having the central axis 21 as a center is formed on the substrate 13 and protrudes from the peripheral wall of the substrate 13. A circular rotary frame 35 that can be rotated is provided in the rotary frame track hole 33, and the plug stopper blade inlet 10 a for accommodating the plug stopper blades 2 a and 2 b in the circular rotation frame 35. 10b, and projecting walls 28a, 28b and projecting walls 38a, 38b for controlling the movement of the cylindrical rotating rods 14a, 14b are provided on the surrounding walls. (See Figure 10)

そして基板１３の上に設けた中心軸２１の両羽に円形回動枠３５と同じ高さまでの間壁２６を設け、円柱形回動棒１４ａと１４ｂを完全に隔離させる。そして基板１３の上には隔離板１５をなくし、プラグ栓刃２ａ、２ｂが略９０度回転された位置に電源となるコンセント端子３７ａ、３７ｂを基板１３の上に直接設ける。（図１１、図１２参照） Then, a wall 26 is provided on both wings of the central shaft 21 provided on the substrate 13 up to the same height as the circular rotary frame 35 to completely separate the cylindrical rotary bars 14a and 14b. Then, the separator plate 15 is eliminated on the substrate 13, and outlet terminals 37a and 37b serving as power sources are directly provided on the substrate 13 at positions where the plug plug blades 2a and 2b are rotated by approximately 90 degrees. (See FIGS. 11 and 12)

さらにコンセント端子３７ａ、３７ｂはプラグ栓刃２ａ、２ｂを両側から挟持する上記実施例１と実施例２の構造と違い、コンセント端子を形成する素材の弾性圧力を利用して一側からプラグ栓刃２ａ、２ｂと接触して電源を接通するようにしたものにする。それ以外のところは実施例１と同様にする。（図１３参照） Further, the outlet terminals 37a and 37b are different from the structures of the first embodiment and the second embodiment in which the plug plug blades 2a and 2b are sandwiched from both sides, and the plug plug blade from one side using the elastic pressure of the material forming the outlet terminal. 2a and 2b are brought into contact with the power source. The rest is the same as in Example 1. (See Figure 13)

この実施例は上記構造により形成し、これを使用する際は、プラグ１をコンセントに差入すると、プラグ栓刃２ａ、２ｂはプラグ栓刃差入孔２０ａ、２０ｂを通って直接円形回動枠３５に貫通されたプラグ栓刃差入口１０ａ、１０ｂの中に入って、先端部はコンセント基板１３の底面に接触する。それまでのプラグ栓刃が通る場所はすべて空間になってあるので、プラグ１は抵抗なく差し抜き可能になる。 This embodiment is formed by the above structure, and when this is used, when the plug 1 is inserted into the outlet, the plug plug blades 2a and 2b pass directly through the plug plug blade insertion holes 20a and 20b. The tip end part contacts the bottom surface of the outlet board 13 by entering the plug plug blade inlets 10 a and 10 b penetrating through 35. Since all the places through which the plug plug blades pass are spaces, the plug 1 can be inserted and removed without resistance.

そして、プラグ１を時計方向に回転させると、プラグ栓刃２ａ、２ｂの側面が突出壁２８ａ、２８ｂを推動して円形回動枠３５が回転し始め、プラグ栓刃２ａ、２ｂに設けられたプラグ栓刃孔３ａ、３ｂが円柱形回動棒１４ａ、１４ｂとそれぞれ一直線になった時、突出壁３８ｂ、３８ａがそれぞれ円柱形回動棒１４ａ、１４ｂの先端部に当接され、突出壁３８ａ、３８ｂの推動作用で、プラグ栓刃２ａ、２ｂと円柱形回動棒１４ａ、１４ｂが同じ高さでの同歩回転を始める。そしてプラグが略９０度回転された時は、プラグ栓刃２ａ、２ｂの下の部分は、円柱形回動棒１４ａ、１４ｂの先端部分がプラグ栓刃孔３ａ、３ｂの中に挿通され、プラグ１が完全にロックされる。一方プラグ栓刃２ａ、２ｂの上の部分はコンセント端子３７ａ、３７ｂと接触され、電源が接通される。そしてプラグ１を抜き出す際は、挿入のときと逆の方向へ操作すれば、相反の作用により元の状態に戻る。（図１０、図１１、図１２、図１３参照） When the plug 1 is rotated in the clockwise direction, the side surfaces of the plug plug blades 2a and 2b thrust the projecting walls 28a and 28b so that the circular rotary frame 35 starts to rotate, and the plug plug blades 2a and 2b are provided. When the plug plug blade holes 3a and 3b are aligned with the cylindrical rotary bars 14a and 14b, the protruding walls 38b and 38a are brought into contact with the distal ends of the cylindrical rotary bars 14a and 14b, respectively, and the protruding wall 38a. 38b, the plug blades 2a and 2b and the cylindrical rotary rods 14a and 14b start the same step rotation at the same height. When the plug is rotated approximately 90 degrees, the tip portions of the cylindrical rotary rods 14a and 14b are inserted into the plug plug blade holes 3a and 3b at the lower portions of the plug plug blades 2a and 2b, 1 is completely locked. On the other hand, the upper portions of the plug blades 2a and 2b are brought into contact with the outlet terminals 37a and 37b, and the power supply is connected. When the plug 1 is extracted, if the plug 1 is operated in the opposite direction to that of the insertion, the original state is restored due to the reciprocal action. (See FIGS. 10, 11, 12, and 13)

当実施例での電源が接通された時の抜け止め機制は、コンセントを組み合わせる段階で先に円形回動枠３５を基板１３に設けた回動枠軌道穴３３の中に嵌め込み、その上にコンセント端子３７ａ、３７ｂをネジで固定することで円形回動枠３５を回動枠軌道穴９から抜けられないようにし、さらに円形回動枠３５の内側の上方辺縁を内側に僅かに突出させる。それによって、電源が接通された状態でプラグ１が引っ張られた場合、プラグ栓刃孔３ａ、３ｂには円柱形回動棒１４ａ、１４ｂがそれぞれ差通されてあるため安定されるし、円柱形回動棒１４ａ、１４ｂの回動支点となる一端は基板１３に軸着されてあり、もう一端は円形回動枠３５の内側壁の突出された辺縁に係止され抜けられなくなり、また円形回動枠３５は上述の回動枠軌道穴３３の中に嵌合されてあるので、コンセント全体が一体化され抜け止め状態となる。 The retaining mechanism when the power source is connected in the present embodiment is such that the circular rotating frame 35 is first fitted into the rotating frame track hole 33 provided in the substrate 13 at the stage of combining the outlets, and the upper part thereof. By fixing the outlet terminals 37a and 37b with screws, the circular rotating frame 35 is prevented from being removed from the rotating frame track hole 9, and the upper edge inside the circular rotating frame 35 is slightly protruded inward. . Thereby, when the plug 1 is pulled in a state where the power supply is connected, the cylindrical rotary rods 14a and 14b are inserted into the plug plug blade holes 3a and 3b, respectively. One end, which is a rotation fulcrum of the shape rotation rods 14a, 14b, is pivotally attached to the substrate 13, and the other end is locked to the protruding edge of the inner wall of the circular rotation frame 35 and cannot be removed. Since the circular rotation frame 35 is fitted in the rotation frame track hole 33 described above, the entire outlet is integrated and is prevented from coming off.

そしてコンセントにプラグが挿入されていない時、円形回動枠３５が勝手に回転され、プラグ差入口が移動されることのないようにするためには、円形回動枠３５と基板１３に設けた回動枠軌道穴３３との間に適度の摩擦力か、あるいは一定の弾性を持たせる。他のところは上記実施例１と同様にする。 When the plug is not inserted into the outlet, the circular rotary frame 35 is rotated on its own, and the plug inlet is provided on the circular rotary frame 35 and the substrate 13 so as not to move. Appropriate frictional force or a certain degree of elasticity is given to the rotation frame track hole 33. The rest is the same as in the first embodiment.

当発明は、電源となるコンセント端子の設け手段として、上記実施例１と実施例２においては基板１３の上に隔離板１５を設け、隔離板１５の上にコンセント端子１６ａ、１６ｂを設けた構造に代わり、実施例３においては隔離板１５をなくし、コンセント端子３７ａ、３７ｂを直接基板１３の上に設けたのだが、これらの手段はお互いに置き換え、又は部分的に組み替えることができるので、それについて下記説明する。 The present invention has a structure in which a separator 15 is provided on a substrate 13 and outlet terminals 16a and 16b are provided on the separator 15 in the first and second embodiments as means for providing a receptacle terminal serving as a power source. Instead, in the third embodiment, the separator 15 is eliminated and the outlet terminals 37a and 37b are provided directly on the substrate 13. However, these means can be replaced with each other or partially rearranged. Is described below.

まず、実施例１の場合、隔離板１５をなくして、コンセント端子を直接基板１３の上に設置することができる。その場合、プラグ栓刃２ａ、２ｂを両側から挟持して電源を接通するコンセント端子１６ａ、１６ｂ代わりに、素材の弾性を利用して、プラグ栓刃を片側から接触して電源を接通させることができるコンセント端子３７ａ、３７ｂを直接基板１３の上のプラグ栓刃２ａ、２ｂが略９０度回転された位置に対向して設ける。（図１４参照） First, in the case of Example 1, the separator 15 can be eliminated and the outlet terminal can be installed directly on the substrate 13. In that case, instead of the outlet terminals 16a and 16b for holding the plug plug blades 2a and 2b from both sides and connecting the power source, the plug plug blade is contacted from one side to connect the power source using the elasticity of the material. Outlet terminals 37a and 37b which can be provided are directly opposed to the positions where the plug plug blades 2a and 2b on the substrate 13 are rotated by approximately 90 degrees. (See Figure 14)

従って、回動枠軌道穴９の中に回動枠４を嵌入させた後、電源の接通状態で回動枠４を押さえて固定する役目を果たせるため、回動枠軌道穴９代わりに回動枠軌道穴９と同じ軌道でありながら、回動枠４が抜けないようにした回動枠軌道穴４０を基板１３の周壁を突出させて設けるが、回動枠軌道穴４０は、コンセント端子３７ａ、３７ｂを設ける位置を、回動枠４を嵌入させるときの嵌め込み口として残して、ほかの回動枠軌道穴の上部辺縁を内側に向けて僅かに突出させてなる辺縁４１を設ける。そしてコンセントを組み立てる際に、まず回動枠軌道穴４０の辺縁４１を設けていない嵌め込む口から回動枠４を嵌めこみ、その上にコンセント端子３７ａ、３７ｂを固着する。すると嵌め込まれた回動枠４は辺縁４１々コンセント端子３７ａ、３７ｂの作用で、どの方位に回されても抜けることができなくなる。（図１５参照） Therefore, after the rotating frame 4 is inserted into the rotating frame track hole 9, the rotating frame 4 can be pressed and fixed in the connected state of the power source. Although the same orbit as the moving frame track hole 9 is provided, the rotating frame track hole 40 that prevents the rotating frame 4 from being pulled out is provided by protruding the peripheral wall of the substrate 13. The positions where 37a and 37b are provided are left as fitting holes when the rotating frame 4 is inserted, and an edge 41 is formed by slightly projecting the upper edge of another rotating frame track hole inward. . Then, when assembling the outlet, first, the rotating frame 4 is fitted from the opening into which the edge 41 of the rotating frame track hole 40 is not provided, and the outlet terminals 37a and 37b are fixed thereon. Then, the fitted rotation frame 4 cannot be removed regardless of which direction it is rotated by the action of the edge 41 and the outlet terminals 37a and 37b. (See Figure 15)

次に、実施例２の場合は、隔離板１５をなくし、プラグ栓刃２ａ、２ｂを両側から挟持して電源を接通するコンセント端子１６ａ、１６ｂをそのまま直接基板１３の上の単体軌道枠軌道穴３６ａ、３６ｂの両側から架設してもよいし、コンセント端子１６ａ、１６ｂ代わりに、素材の弾性を利用して、プラグ栓刃を片側から接触して電源を接通させることができるコンセント端子３７ａ、３７ｂを直接基板１３の上単体軌道枠軌道穴３６ａ、３６ｂに側面から対向して設けることも可能である。そして単体回動枠８ａ、８ｂをはめ込んだ後、抜けないようにするために、コンセント端子を設ける口以外の辺縁を上記実施例１同様、単体軌道枠軌道穴３６ａ、３６ｂを内側に向け僅かに突出させてなる辺縁４１を設ける。そして、これを組み立てる際は、まず単体回動枠８ａ、８ｂをそれぞれ単体軌道枠軌道穴３６ａ、３６ｂにはめ込んだ後、回動枠４を辺縁４１を設けてない嵌め込む口から回動枠４を嵌めこみ、その上にコンセント端子３７ａ、３７ｂもしくはコンセント端子１６ａ、１６ｂを固着すればよい。（図１６参照） Next, in the case of the second embodiment, the separator plate 15 is eliminated, and the plug terminals 2a and 2b are sandwiched from both sides and the outlet terminals 16a and 16b for connecting the power supply are directly connected to the single track frame track on the substrate 13 as they are. It may be installed from both sides of the holes 36a and 36b, or instead of the outlet terminals 16a and 16b, using the elasticity of the material, the outlet terminal 37a can be connected to the power source by contacting the plug plug blade from one side. , 37b can also be provided directly on the upper single track frame track holes 36a, 36b of the substrate 13 so as to face each other. Then, in order to prevent the single turn frames 8a and 8b from being pulled out, the edges other than the port where the outlet terminal is provided are slightly facing the single track frame track holes 36a and 36b inward as in the first embodiment. An edge 41 is provided so as to project. When this is assembled, first, the single turn frames 8a and 8b are first fitted into the single track frame race holes 36a and 36b, respectively, and then the turn frame 4 is opened from the opening into which the edge 41 is not provided. 4 may be fitted, and the outlet terminals 37a and 37b or the outlet terminals 16a and 16b may be fixed thereon. (See Figure 16)

そして実施例３の場合は、回動枠軌道穴３３の中に回動可能な円形回動枠３５を嵌めこんでから、基板１３の上に設けたコンセント端子３７ａ、３７ｂをなくし、実施例２のプラグ栓刃軌道孔１７ａ、１７ｂとコンセント端子１６ａ、１６ｂと円形中心孔２７などが設けられた隔離板１５を、丸こと基板１３の上に載設すればよい。（図１８参照） In the case of the third embodiment, after inserting the rotatable circular rotating frame 35 into the rotating frame track hole 33, the outlet terminals 37a and 37b provided on the substrate 13 are eliminated, and the second embodiment is applied. The separator plate 15 provided with the plug plug blade raceway holes 17a and 17b, the outlet terminals 16a and 16b, the circular center hole 27 and the like may be mounted on the substrate 13 in a round shape. (See Figure 18)

上記三つの実施例の部分的置き換えは、当発明の成り立つ原理においても、機能性においても問題がないので、生産設計の段階で構造の簡素化、コストの削減、部品を構成する素材の性質など様々の要因を考慮した上で、選択することが可能である。 The partial replacement of the above three embodiments has no problem in terms of the principle and functionality of the present invention, so the structure is simplified at the production design stage, the cost is reduced, the properties of the materials constituting the parts, etc. It is possible to select after considering various factors.

また、当発明に置いて、プラグをコンセントに挿入して所定の円心と軌道で略９０度回転させる手段として、回動天井板１９を設けず、プラグ挿入口２０ａ、２０ｂ代わりにプラグを挿入して略９０度回動可能にしたプラグ栓刃軌道孔４２ａ、４２ｂを直接コンセントカバー２９に設けることも可能である。（図１７参照） Further, in the present invention, as a means for inserting the plug into the outlet and rotating it approximately 90 degrees with a predetermined circular center and track, the rotating ceiling plate 19 is not provided and the plug is inserted instead of the plug insertion ports 20a and 20b. It is also possible to directly provide the plug cover blade raceway holes 42a and 42b in the outlet cover 29 so as to be rotatable about 90 degrees. (See Figure 17)

しかし、そうした場合は、コンセントの内部が、いつも大きな開き口によって外側に解放されたことになり、その開放口から埃と虫が侵入しやすく、プラグ栓刃の回転軌道の精確度と安定性が弱くなる、コンセントの外観形状が醜いなどの問題があるので、実用性に欠ける。 However, in such a case, the inside of the outlet is always released to the outside by a large opening, dust and insects can easily enter from the opening, and the accuracy and stability of the rotation path of the plug stopper blade is improved. Since there are problems such as weakening and the appearance of the outlet being ugly, it is not practical.

また、当発明において、コンセントにプラグが挿入されていない時、阻止体が勝手に回転されないようにする方法や、電源となるコンセント端子の形状、コンセント端子とプラグとの接続方法などについては、前記した三つの実施例の方法に限らない。 Further, in the present invention, when the plug is not inserted into the outlet, the method of preventing the blocking body from rotating freely, the shape of the outlet terminal serving as a power source, the method of connecting the outlet terminal and the plug, etc. The method is not limited to the methods of the three embodiments.

そして、上記記載の実施例１、実施例２、実施例３を製品化する際の素材は、コンせント端子の電源接続部分は、銅などの弾性と適度の強度を有する金属導体を使用し、他の部品はなるべく合成樹脂や合成金属等の十分な耐熱性と、強度、耐久性などを備えた材料の絶縁体であって、電源の短絡や燃焼現象などを完全に防止可能な素材を採用する。 The material used for commercializing the above-described Example 1, Example 2, and Example 3 uses a metal conductor having elasticity and appropriate strength, such as copper, for the power supply connection portion of the constant terminal. Other parts are insulators of materials with sufficient heat resistance, strength, durability, etc., such as synthetic resin and synthetic metal as much as possible, and materials that can completely prevent power supply short circuit and combustion phenomenon etc. adopt.

また、当発明は、コンセントのカバーや外筐の形状を変えるだけで、壁や床に設けられるアウトレットやコネクタボディなどの同じ種類のコンセントにも適用する。そして、日本ではプラグの左側の接地栓刃が右側の栓刃より僅かに長い（左側９ｍｍ、右側７ｍｍ）場合があるのだが、長いほうの左側のサイズに合わせれば影響を及ばないので、適用する。（図２参照） The present invention is also applicable to the same type of outlets such as outlets and connector bodies provided on walls and floors by simply changing the shape of the outlet cover and outer casing. In Japan, the ground plug blade on the left side of the plug may be slightly longer than the right one (9 mm on the left side and 7 mm on the right side). . (See Figure 2)
