Description

この発明は、各種の電気機器のプラグを接続し、電気機器に電源を供給する電源コンセントに関するものである。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power outlet for connecting plugs of various electric devices and supplying power to the electric devices.

従来、各種の電気機器を接続する電源コンセントは、対向した２枚の接触板で電極を形成し、絶縁材料で形成したコンセント本体内に一対の電極を収納して構成されている。そして、プラグの電極である一対の刃をコンセント本体の差し込み穴に挿入し、各刃を接触板の板バネ作用で弾性的に挟持してプラグを接続し、電気機器を導通可能とする構造である。また、電源コンセントは、その信頼性、耐久性、バネ保持力の差で、一般用、工業用、医療用の等級がある。   2. Description of the Related Art Conventionally, a power outlet for connecting various electric devices is configured such that electrodes are formed by two opposed contact plates, and a pair of electrodes is housed in an outlet body formed of an insulating material. Then, a pair of blades, which are the electrodes of the plug, are inserted into the insertion holes of the outlet main body, and the respective blades are elastically sandwiched by the leaf spring action of the contact plate to connect the plugs, thereby enabling electrical equipment to conduct. is there. In addition, power outlets are classified into general, industrial, and medical grades based on differences in reliability, durability, and spring holding force.

かかる電源コンセントにおいて、一般家庭で用いられるものでも、プラグが容易に離脱することがないように所定のバネ保持力が設定され、刃の差し込みにはこの摩擦抵抗力に抗する力を要する。電源コンセント及びプラグの製品ごとのバラツキや寸法誤差によっては、プラグの抜き差しが極めて堅いものがあり、こうしたものは、非力な子供や主婦、特に老人にとってはプラグの着脱が容易ではなかった。   In such a power outlet, a predetermined spring holding force is set so that the plug is not easily detached even in a general household, and a force that resists this frictional resistance is required for insertion of the blade. Depending on variations and dimensional errors between power outlets and plugs in some products, plugs are very hard to plug in and out, and these plugs are not easy for weak children and housewives, especially elderly people.

一方、接触板と刃の面接触で導通状態となるため、刃を完全にコンセント内に挿入することなく不完全な状態でも電気が流れ、露出した刃に触れて感電するなど、安全性にも課題があった。こうしたことを防止するため、刃をコンセント内に挿入した後、ネジ締めして堅固に固定するロック方式のものも信頼性を要する分野では用いられるが、頻繁にプラグを抜き差しする一般家庭用としては使い勝手が悪く、不向きである。   On the other hand, since the conductive state is established by the surface contact between the contact plate and the blade, electricity flows even in an incomplete state without completely inserting the blade into the outlet, and safety such as electric shock by touching the exposed blade. There were challenges. To prevent this, a lock type that inserts the blade into the outlet and tightens it with a screw to firmly fix it is also used in fields requiring reliability, but for general household use where plugs are frequently removed and inserted. It is inconvenient and unsuitable.

この発明は、これらの課題を解決することを目的とするもので、接触板が開閉する構造とし、力を要せずにプラグを抜き差しすることができる電源コンセントを提供するものである。また、安全で極めて使い勝手の良い電源コンセントを提供することを目的とするものである。   SUMMARY OF THE INVENTION An object of the present invention is to provide a power outlet which has a structure in which a contact plate is opened and closed and which can be plugged in and out without requiring force.

Then, the sphere 24 pushes and spreads the contact plate 20 at the upper position to make it open. Then, the sphere 24 at the lower position is moved to the upper position by the pressing operation of the push button 30, and the sphere 24 at the upper position is moved to the lower position by the lower end abutting when the blade 13 is inserted. is there.

第２の発明は、電極である接触板４０とこれと対向した押圧体５０とをコンセント本体１０内に一対収納し、プラグ１２の刃１３を押圧体５０が接触板２０に弾性的に押圧してプラグ１２を接続する電源コンセントであって、押圧体５０が開いた状態で刃１３を差し込み、刃１３の挿入で自動的に押圧体５０を閉じ、押圧体５０が開いた状態で刃１３を引き抜くようにした押圧体５０の開閉機構を設け、コンセント本体１０に設けた押しボタン３０の押圧操作で押圧体５０を開いた状態とすることを特徴とするものである。   In the second invention, the contact plate 40 as an electrode and the pressing body 50 facing the electrode are housed in a pair in the outlet main body 10, and the pressing body 50 elastically presses the blade 13 of the plug 12 against the contact plate 20. A power outlet for connecting the plug 12 by inserting the blade 13 with the pressing body 50 opened, automatically closing the pressing body 50 by inserting the blade 13, and closing the blade 13 with the pressing body 50 open. A mechanism for opening and closing the pressing body 50 so as to be pulled out is provided, and the pressing body 50 is opened by a pressing operation of the push button 30 provided on the outlet main body 10.

また、この電源コンセントの具体的な構成としては、接触板４０と押圧体５０の間隔内に球体２４を設け、球体２４を移動可能な上下２つの位置で保持するとともに、下方位置で押圧体５０が閉じた状態で、上方位置で球体２４が押圧体５０を駆動して開いた状態とし、下方位置にある球体２４を押しボタン３０の押圧操作で上方位置へ移動させ、上方位置にある球体２４を刃１３の挿入で下端が当接して下方位置に移動させるように構成するものである。   Further, as a specific configuration of the power outlet, a sphere 24 is provided in the space between the contact plate 40 and the pressing body 50, the sphere 24 is held at two movable upper and lower positions, and the pressing body 50 is Is closed, the sphere 24 drives the pressing body 50 at the upper position to open the sphere 24, and moves the sphere 24 at the lower position to the upper position by pressing the push button 30, and moves the sphere 24 at the upper position. The lower end is brought into contact with the blade 13 when the blade 13 is inserted, and is moved to a lower position.

また、この発明の電源コンセントにおいて、上記押しボタン３０がコンセント口の一つ分のスペースを占めるように配置するものである。   In the power outlet according to the present invention, the push button 30 is disposed so as to occupy one space of the outlet.

第１の発明によれば、接触板２０が開いた状態でプラグ１２を抜き差しするので、何らの力を要せずに極めて容易にプラグ１２を着脱することができるとともに、コンセント本体１０に設けた押しボタン３０の押圧操作で接触板２０を開いた状態とするので、接触板２０の開閉操作も簡単でその使い勝手に優れるものである。同様に、第２の発明によれば、押圧体５０が開いた状態でプラグ１２を抜き差しするので、極めて容易にプラグ１２を着脱することができる。   According to the first invention, since the plug 12 is inserted and removed with the contact plate 20 opened, the plug 12 can be attached and detached extremely easily without any force, and is provided on the outlet main body 10.

以下にこの発明の実施の形態を、図面を用いて具体的に説明する。
図１から図１１は第１の発明に基づく実施例である。図に示すように、電源コンセントは、絶縁材料で形成したコンセント本体１０内に、対向した接触板２０で形成した一対の電極が収納され、それぞれの電極には導通金具２１を介して電源コードの各端子２２が接続されている。接触板２０は、導電性金属板をＵ字状に折り曲げて弾性力を有した板バネ部材で、上半部に間隔を狭めた接触面２０ａを形成している。各接触面２０ａの上端は外方向へ開き、接触板２０の間隔で上端に溝状の開口面を形成し、この開口面がコンセント本体１０の各差し込み穴１１に対向し、プラグ１２の刃１３を差し込み穴１１から挿入して接触板２０の間隔内に差し込まれる。 Embodiments of the present invention will be specifically described below with reference to the drawings.
1 to 11 show an embodiment based on the first invention. As shown in the figure, the power outlet has a pair of electrodes formed by opposed contact plates 20 housed in an outlet main body 10 formed of an insulating material. Each terminal 22 is connected. The contact plate 20 is a leaf spring member having a resilient force by bending a conductive metal plate into a U-shape, and forms a contact surface 20a with a narrow interval in an upper half portion. The upper end of each contact surface 20a is opened outward, and a groove-shaped opening surface is formed at the upper end at intervals of the contact plate 20, and this opening surface faces each insertion hole 11 of the outlet main body 10, and the Is inserted from the insertion hole 11 and inserted into the space between the contact plates 20.

接触板２０の下半面２０ｂにはダルマ形状の開孔２３が形成され、下半面２０ｂの間隔内に球体２４が設けられ、この球体２４の左右両側部が対向した開孔２３から覗く（突出する）ことで、球体２４が保持されている。   A dharma-shaped opening 23 is formed in the lower half surface 20b of the contact plate 20, and a sphere 24 is provided within the space between the lower half surfaces 20b. ), The sphere 24 is held.

この電源コンセントは、一対の差し込み穴１１で形成する一つのコンセント口が設けられ、このコンセント口から離れた位置に、押しボタン３０が設けられている。押しボタン３０の軸３１は、押しボタン３０に連動して上下動可能にコンセント本体１０内に挿入され、軸３１の上端部に設けたコイルバネ３２で、押しボタン３０及び軸３１は上方へ付勢されている。   This power outlet is provided with one outlet formed by a pair of insertion holes 11, and a push button 30 is provided at a position away from the outlet. The shaft 31 of the push button 30 is inserted into the outlet main body 10 so as to be able to move up and down in conjunction with the push button 30, and a coil spring 32 provided at the upper end of the shaft 31 urges the push button 30 and the shaft 31 upward. Have been.

軸３１の下端にはコの字状の二股に分かれたテコ棒３４（図３参照）が連結され、各テコ棒３４の先端が、各電極の接触板２０の間隔内底部（下半面２０ｂ間の底部）に挿入され、球体２４の下側に位置している。テコ棒３４の中途位置に支点１５が設けられ、テコ棒３４は支点１５を中心にしてテコの原理で回動可能とされ、軸３１の上下動に連動してテコ棒３４の先端が逆方向へ上下動し、球体２４の底面に当接して球体２４を駆動するように構成されている。   A U-shaped bifurcated leverage rod 34 (see FIG. 3) is connected to the lower end of the shaft 31. The tip of each leverage rod 34 is connected to the inner bottom of the contact plate 20 of each electrode (between the lower half surface 20b). At the bottom of the sphere 24. The fulcrum 15 is provided at an intermediate position of the lever rod 34, and the lever rod 34 is rotatable around the fulcrum 15 according to the principle of leverage. , And is configured to drive the sphere 24 by contacting the bottom surface of the sphere 24.

図４に、このようにして駆動される球体２４と開孔２３との関係を示す。上記のように開孔２３の形状は、直径が大きい下側大円部２３ａと、これより直径が小さい上側小円部２３ｂが縦に連続したダルマ形状とされている。球体２４は左右両側部が開孔２３から覗くことで保持され、下側大円部２３ａで保持される下方位置（２４ａの状態）と、上側小円部２３ｂで保持される上方位置（２４ｂの状態）との上下２つの位置で保持される。球体２４が下方位置にあり、テコ棒３４の先端が上昇すると球体２４の底面に当接して球体２４を上方へ駆動し、球体２４は開孔２３に案内されて上昇して上方位置に至る。このように、球体２４は上下２つの位置を移動可能とされている。   FIG. 4 shows the relationship between the sphere 24 and the opening 23 driven in this manner. As described above, the shape of the opening 23 is a Dharma shape in which the lower large circle portion 23a having a large diameter and the upper small circle portion 23b having a smaller diameter are vertically continuous. The spherical body 24 is held by looking through the opening 23 on both left and right sides, and the lower position (state of 24a) held by the lower large circle portion 23a and the upper position (24b) held by the upper small circle portion 23b. (State) and two upper and lower positions. When the spherical body 24 is at the lower position and the tip of the lever stick 34 rises, the spherical body 24 contacts the bottom surface of the spherical body 24 and drives the spherical body 24 upward. The spherical body 24 is guided by the opening 23 and rises to reach the upper position. In this manner, the sphere 24 can be moved up and down two positions.

次にこの電源コンセントの動作を説明する。
プラグ１２を接続していない状態を図１及び２に示す。図に示すように、軸３１はコイルバネ３２の弾発力で上端に位置し、各テコ棒３４の先端は各電極の接触板２０間で下端に位置している。球体２４は、開孔２３の上側小円部２３ｂで保持される上方位置に保持されている。そのため、球体２４の側部の覗き量（突出量）が小さく、その分接触板２０を板バネ作用に抗して外方向へ押し広げ、接触面２０ａが離れた状態（開いた状態）となっている。 Next, the operation of the power outlet will be described.
FIGS. 1 and 2 show a state in which the plug 12 is not connected. As shown in the figure, the shaft 31 is located at the upper end by the resilient force of the coil spring 32, and the tip of each lever bar 34 is located at the lower end between the contact plates 20 of the electrodes. The sphere 24 is held at an upper position held by the upper small circle portion 23 b of the opening 23. Therefore, the peeping amount (projection amount) of the side portion of the sphere 24 is small, and the contact plate 20 is pushed outward by the corresponding amount against the leaf spring action, and the contact surface 20a is separated (opened state). ing.

この状態でプラグ１２の刃１３を差し込み穴１１から挿入する。接触面２０ａが開いているから、何らの摩擦抵抗が無く無負荷のまま刃１３を差し込むことができ、刃１３の下端が球体２４に当接して手応えを得て、さらにプラグ１２を一押しする。その結果、球体２４が下方へ駆動され、開孔２３の下側大円部２３ａで保持される下方位置に移動する。   In this state, the blade 13 of the plug 12 is inserted through the insertion hole 11. Since the contact surface 20a is open, the blade 13 can be inserted without any load without any frictional resistance, and the lower end of the blade 13 comes into contact with the sphere 24 to obtain a response, and further pushes the plug 12 once. . As a result, the sphere 24 is driven downward and moves to a lower position held by the lower great circle portion 23a of the opening 23.

この球体２４の下方位置では、球体２４の側部の覗き量が大きくなり、接触板２０の板バネ作用で対向した接触面２０ａが近接した閉じた状態となり、刃１３と接触面２０ａが完全に接触した状態となる。このようにして、刃１３の挿入で自動的に接触板２０を閉じ、電源コンセントにプラグ１２が接続される。このプラグの接続操作においては、何らの摩擦抵抗の無い状態から、球体２４に当接した手応え、さらに接触面２０ａが閉じる感触が得られ、操作感が極めて良い。図５及び６に、こうして電源コンセントにプラグ１２を接続した状態を示す。   In the position below the spherical body 24, the amount of peeping on the side of the spherical body 24 becomes large, and the contact surface 20a opposed by the leaf spring action of the contact plate 20 is brought into a close state in which the blade 13 and the contact surface 20a are completely closed. It comes into contact. In this way, the insertion of the blade 13 automatically closes the contact plate 20, and the plug 12 is connected to the power outlet. In the operation of connecting the plug, a feeling of contact with the sphere 24 and a feeling of closing the contact surface 20a are obtained from a state where there is no frictional resistance, and the operation feeling is extremely good. FIGS. 5 and 6 show a state in which the plug 12 is connected to the power outlet.

次に、電源コンセントからプラグ１２を引き抜くには押しボタン３０を押圧する。押しボタン３０の押圧で軸３１が下降し、テコ棒３４の先端が上昇して球体２４を駆動し、球体２４は開孔２３の上側小円部２３ｂで保持される上方位置へ移動する。その結果、球体２４が接触板２０を押し広げて接触面２０ａが開いた状態となり、何らの摩擦抵抗が無く電源コンセントからプラグ１２を引き抜くことができる。この状態を図７及び８に示す。   Next, the push button 30 is pressed to pull out the plug 12 from the power outlet. When the push button 30 is pressed, the shaft 31 moves down, the tip of the lever stick 34 rises and drives the sphere 24, and the sphere 24 moves to an upper position held by the upper small circular portion 23 b of the opening 23. As a result, the spherical body 24 spreads the contact plate 20 to open the contact surface 20a, and the plug 12 can be pulled out from the power outlet without any frictional resistance. This state is shown in FIGS.

押しボタン３０から指を離せば、コイルバネ３２の弾発力で軸３１が上端位置に復帰し、テコ棒３４の先端が下降する。球体２４は上方位置のまま保持され、電源コンセントは図１及び２に示した状態となる。   When the finger is released from the push button 30, the shaft 31 returns to the upper end position by the elastic force of the coil spring 32, and the tip of the lever stick 34 descends. The sphere 24 is held in the upper position, and the power outlet is in the state shown in FIGS.

図９は、球体２４を上下二つの位置で保持する他の方法を示すものである。
本例では、接触板２０に開孔２３を設ける代わりに、外方向へ膨出した凹面２５を接触板２０の下半面２０ｂに形成している。凹面２５は、膨出量が大きい下側大円弧面部２５ａと、これより膨出量が小さい上側小円弧面部２５ｂが連続した形状とされている。球体２４は左右両側部が対向した凹面２５に嵌まることで保持され、下側大円弧面部２５ａに嵌まって保持される下方位置（２４ａの状態）と、上側小円弧面部２５ｂに嵌まって保持される上方位置（２４ｂの状態）との上下２つの位置で保持される。 FIG. 9 shows another method of holding the sphere 24 at two upper and lower positions.
In this example, instead of providing the opening 23 in the contact plate 20, a concave surface 25 bulging outward is formed on the lower half surface 20 b of the contact plate 20. The concave surface 25 has a shape in which a lower large arc surface portion 25a having a large bulging amount and an upper small arc surface portion 25b having a smaller bulging amount are continuous. The spherical body 24 is held by being fitted to the concave surface 25 whose left and right sides are opposed to each other, and is fitted to and held by the lower large arc surface 25a and the upper small arc surface 25b. It is held at two positions above and below the held upper position (state 24b).

本例において、球体２４が下方位置では、接触板２０の板バネ作用で閉じた状態である（イの状態）。テコ棒３４の先端の上昇で球体２４を上方へ駆動し、球体２４は凹面２５に案内されて上昇して上方位置に至る。この膨出量が小さい上側小円弧面部２５ｂで保持される上方位置では、その分接触板２０を板バネ作用に抗して外方向へ押し広げ、接触板２０が開いた状態となる（ロの状態）。電源コンセントの動作は、前例と同様である。   In the present example, when the sphere 24 is at the lower position, the contact plate 20 is closed by the leaf spring action of the contact plate 20 (state A). The spherical body 24 is driven upward by the upward movement of the tip of the lever stick 34, and the spherical body 24 is guided by the concave surface 25 and rises to reach the upper position. At the upper position where the bulging amount is small and held by the upper small circular arc surface portion 25b, the contact plate 20 is pushed outward and spreads against the leaf spring action, and the contact plate 20 is opened (b). Status). The operation of the power outlet is the same as in the previous example.

図１０及び１１にこのようにして形成される電源コンセントの適用例を示す。図１０は露出型コンセントで、一対の差し込み穴１１で形成した一つのコンセント口と、このコンセント口に対応した押しボタン３０を設けている。図１１は壁埋め込み型コンセントで、同様に一つのコンセント口と、これに対応した押しボタン３０を設けていて、押しボタン３０がコンセント口の一つ分のスペースを占るように配置し、２口コンセント用の化粧カバー１７が取り付けられている。その他、壁埋め込み型コンセントに接続するタップ型のコンセントにも適用可能である。   10 and 11 show application examples of the power outlet formed in this manner. FIG. 10 shows an exposed type outlet provided with one outlet formed by a pair of insertion holes 11 and a push button 30 corresponding to the outlet. FIG. 11 shows a wall-embedded outlet, which is also provided with one outlet and a corresponding push button 30, and the push button 30 is arranged so as to occupy one space of the outlet. A decorative cover 17 for a mouth outlet is attached. In addition, the present invention can be applied to a tap-type outlet connected to a wall-mounted outlet.

図１２から図１６は第２の発明に基づく実施例であり、図中前例と同一の符号は同一の部材・構成であるので説明を省略する。図に示すように、この電源コンセントは、導通金具２１を介して電源コードの各端子２２が接続された電極である一対の接触板４０が、コンセント本体１０内に収納され、プラグ１２の刃１３を接触板２０に押圧する押圧体５０が各接触板４０と対向して設けられている。押圧体５０は、上端に近接した位置に支点５１を設けて回動可能とされ、下方背面に設けたコイルバネ５３で閉じる方向へ付勢されている。   FIGS. 12 to 16 show an embodiment based on the second invention. In the drawings, the same reference numerals as those in the previous example denote the same members and configurations, and a description thereof will be omitted. As shown in FIG. 1, the power outlet includes a pair of contact plates 40, which are electrodes to which respective terminals 22 of a power cord are connected via conductive metal fittings 21, housed in the outlet main body 10, and a blade 13 of a plug 12. The pressing body 50 that presses the contact plate 20 against the contact plate 20 is provided to face each contact plate 40. The pressing body 50 is rotatable by providing a fulcrum 51 at a position close to the upper end, and is urged in a closing direction by a coil spring 53 provided on the lower back surface.

接触板４０と押圧体５０の間隔内には前例と同様な働きをする球体２４が設けられ、球体２４が当接する接触板４０の表面（押圧体５０に対向した面）に、上方位置に凹部４１、下方位置に通孔４２が設けられ、凹部４１と通孔４２を連通する溝路４３（図１２、ロ参照）が設けられている。その結果、溝路４３に案内されて上下移動する球体２４は、凹部４１に嵌まって保持される上方位置と、通孔４２から側部が覗いて保持される下方位置との上下２つの位置で保持される。   Within the space between the contact plate 40 and the pressing body 50, a sphere 24 having the same function as in the previous example is provided, and the surface of the contact plate 40 with which the sphere 24 contacts (the surface facing the pressing body 50) is recessed at an upper position. 41, a through hole 42 is provided at a lower position, and a groove 43 (see FIG. 12, b) communicating the concave portion 41 and the through hole 42 is provided. As a result, the spherical body 24 that moves up and down while being guided by the groove 43 has two upper and lower positions, an upper position where the sphere 24 is fitted and held in the concave portion 41 and a lower position where the side is held through the through hole 42. Is held.

球体２４の下方に球体２４の底面に当接する他の球体４４が設けられ、この球体４４の下方に、テコ棒３４の先端が底面に当接して上下動移動可能なスライド体４６が設けられている。スライド体４６は図１３に示すように形成され、その上面は、手前側平坦部４６ａと背面に向かって上昇する傾斜部４６ｂで形成され、中央には球体４４を受けるための溝４６ｃが形成されている。   Another sphere 44 is provided below the sphere 24 and abuts against the bottom surface of the sphere 24. Below the sphere 44, a slide 46 is provided which can move up and down with the tip of the lever stick 34 abutting against the bottom surface. I have. The slide body 46 is formed as shown in FIG. 13, and the upper surface thereof is formed by a flat portion 46a on the front side and an inclined portion 46b rising toward the rear surface, and a groove 46c for receiving the sphere 44 is formed in the center. ing.

次にこの電源コンセントの動作を説明する。
プラグ１２を接続していない図１２の状態では、球体２４は凹部４１に嵌まって上方位置で保持され、コイルバネ５３に抗して押圧体５０を押し広げ、押圧体５０が開いた状態である。スライド体４６は下端に位置し、球体４４はフリーの状態でスライド体４６上に載置している。 Next, the operation of the power outlet will be described.
In the state of FIG. 12 in which the plug 12 is not connected, the sphere 24 is fitted in the concave portion 41 and held at the upper position, the pressing body 50 is spread out against the coil spring 53, and the pressing body 50 is open. . The slide 46 is located at the lower end, and the sphere 44 is placed on the slide 46 in a free state.

この状態でプラグ１２の刃１３を差し込み穴１１から挿入すると、何らの摩擦抵抗が無く無負荷のまま刃１３を差し込むことができ、刃１３の下端が球体２４に当接して手応えを得て、さらにプラグ１２を一押しする。その結果、球体２４が下方へ駆動され、通孔４２から側部が覗いて保持される下方位置に移動する。この球体２４の移動に伴い、押圧体５０が支点５１を中心にして閉じる方向へ回動して刃１３に当接し、コイルバネ３２の弾発力で接触板２０に刃１３を押圧してプラグ１２が接続され、球体４４は溝４６ｃに案内されて傾斜部４６ｂへ移動する。図１４に、こうして電源コンセントにプラグ１２を接続した状態を示す。   When the blade 13 of the plug 12 is inserted from the insertion hole 11 in this state, the blade 13 can be inserted without any frictional resistance and without load, and the lower end of the blade 13 contacts the sphere 24 to obtain a response, Further, the plug 12 is pressed once. As a result, the sphere 24 is driven downward, and moves to a lower position where the side portion is viewed and held through the through hole 42. Along with the movement of the sphere 24, the pressing body 50 rotates in the closing direction about the fulcrum 51 to abut on the blade 13, and presses the blade 13 against the contact plate 20 by the elastic force of the coil spring 32, and Is connected, and the sphere 44 is guided by the groove 46c and moves to the inclined portion 46b. FIG. 14 shows a state in which the plug 12 is connected to the power outlet in this manner.

次に、電源コンセントからプラグ１２を引き抜くには押しボタン３０を押圧する。押しボタン３０の押圧で軸３１が下降し、テコ棒３４の先端が上昇してスライド体４６を駆動し、スライド体４６の上昇で球体４４及び球体２４を駆動する。傾斜部４６ｂに位置した球体４４は、押圧体５０を若干押し広げて刃１３への押圧を解除し、同時に球体２４を駆動し、球体２４は通孔４２から外れ（図１５の状態）、さらに、スライド体４６の上昇で、球体２４は凹部４１に保持される上方位置へ移動する。その結果、押圧体５０が開いた状態となり（図１６の状態）、何らの摩擦抵抗が無く電源コンセントからプラグ１２を引き抜くことができる。押しボタン３０を押圧を解除すれば、プラグ１２を接続していない図１２の状態に復帰する。この電源コンセントにおいては、球体２４を他の球体４４で駆動するようにしたので、両球体の当接面が自在に変動して円滑な駆動が図られている。なお、球体２４を保持する手段としては、前例のように接触板４０に開孔を設けるようにしてもよい。   Next, the push button 30 is pressed to pull out the plug 12 from the power outlet. When the push button 30 is pressed, the shaft 31 is lowered, the tip of the lever stick 34 is raised, and the slide body 46 is driven. The sphere 44 located on the inclined portion 46b slightly expands the pressing body 50 to release the pressing against the blade 13, and simultaneously drives the sphere 24, and the sphere 24 comes off from the through hole 42 (the state of FIG. 15). When the slide body 46 rises, the sphere 24 moves to the upper position held by the recess 41. As a result, the pressing body 50 is opened (the state of FIG. 16), and the plug 12 can be pulled out of the power outlet without any frictional resistance. When the pressing of the push button 30 is released, the state returns to the state of FIG. 12 in which the plug 12 is not connected. In this power outlet, the sphere 24 is driven by the other sphere 44, so that the contact surfaces of the two spheres are freely changed and smooth driving is achieved. As means for holding the sphere 24, an opening may be provided in the contact plate 40 as in the previous example.
