【発明の属する技術分野】
本発明は、雄雌嵌合式接続器において、差し込みと引き抜きを容易にする技術に関する。
【０００２】
【従来の技術】
差込プラグは、ハウジングの前側に１対の雄型接触片を突出し、ハウジング内に、１対の雄型接触片に接続する１対のビスを設け、１対のビスにコードの１対の電線を接続し、コードをハウジングの後側に引き出している。
【０００３】
接触片可動式の差込プラグは、ハウジングの前部に雄型接触片の基端を回転可能に取り付けて、可動式の雄型接触片を、ハウジングの前方に突出する真直ぐ位置から、ハウジングの側方に突出する折り曲げ位置に変更可能にしている。この差込プラグは、雄型接触片が真直ぐ位置でも、真直ぐ位置から９０度回転した折り曲げ位置でも、雌型接触片を内蔵したコンセントに差し込むことができる。コンセントの周囲の空間状況に応じて、雄型接触片の真直ぐ位置と折り曲げ位置とを使い分けることができる。コンセントへの差し込みが容易である。
【０００４】
特許文献１に開示の差込プラグは、コンセントから引き抜き易くするため、ハウジングの前部に雄型接触片の基端を回転可能に取り付け、ハウジング前部の両側の表面にそれぞれ突起部を設けている。この差込プラグは、雄型接触片を、ハウジングの前方に突出する真直ぐ位置にして、コンセントに差し込む。コンセントから引き抜くときには、ハウジングの後部をいずれか一方の側方に押してハウジングを倒す。すると、ハウジングの倒れた側の突起部がコンセントの表面に当って梃子の支点になり、雄型接触片がコンセントから簡単に抜ける、とのことである。
【０００５】
特許文献２に開示の差込プラグは、コンセントから引き抜き易くするため、ハウジングの前部に雄型接触片の基端を回転可能に取り付け、ハウジングの前部に押し出し部を前方に突出して設けている。この差込プラグは、雄型接触片を、ハウジングの側方に突出する折り曲げ位置にして、コンセントに差し込む。コンセントから引き抜くときには、ハウジングの後部を持ち上げてハウジングを起こす。すると、ハウジングの押し出し部がコンセントの表面に当って梃子の支点になり、雄型接触片がコンセントから簡単に抜ける、とのことである。

【発明が解決しようとする課題】
ところが、接触片可動式の差込プラグは、コンセントの周囲の空間状況に応じて雄型接触片の真直ぐ位置と折り曲げ位置とを使い分けることができ、コンセントへの差し込みが容易であるが、引き抜きが容易であるとは言い難い。
【０００８】
特許文献１に開示の差込プラグは、引き抜き時に梃子の支点になる突起部をハウジングの両側に設けているので、雄型接触片を、ハウジングの一方又は他方の側方に突出する折り曲げ位置にして、コンセントに差し込もうとすると、雄型接触片が突出した側の突起部がコンセントの表面に当って邪魔になり、雄型接触片は、コンセントに内蔵された雌型接触片に差し込まれない。雄型接触片が折り曲げ位置にあると、コンセントに差し込むことができない。この差込プラグは、雄型接触片がハウジングの前方に突出する真直ぐ位置にあるときしか、コンセントに差し込むことができない。差し込みが容易であるとは言い難い。
【０００９】
特許文献２に開示の差込プラグは、引き抜き時に梃子の支点になる押し出し部をハウジングの前方に突出しているので、雄型接触片を、ハウジングの前方に突出する真直ぐ位置にして、コンセントに差し込もうとすると、押し出し部がコンセントの表面に当って邪魔になり、雄型接触片は、コンセントに内蔵された雌型接触片に差し込まれない。雄型接触片が真直ぐ位置にあると、コンセントに差し込むことができない。この差込プラグは、雄型接触片がハウジングの一方又は他方の側方に突出する折り曲げ位置にあるときしか、コンセントに差し込むことができない。差し込みが容易であるとは言い難い。
【００１０】
従って、これらの差込プラグは、差し込みと引き抜きの両方が容易であるとは言い難い。
【００１１】
また、これらの差込プラグは、ハウジング内のビスにコードの電線を接続する構成にしているので、既存の電気器具に使用するときには、その電気器具のコードに接続した既存の差込プラグを取り外し、そのコードに新しい差込プラグを接続することになる。電気器具の差込プラグを取り換える手間が掛る。
【００１２】
【課題を解決するための手段】
１）ハウジングに雄型接触片の基端を回転可能に取り付けて、雄型接触片を、ハウジングの前方に突出する真直ぐ位置から、ハウジングの一方の側方に突出する折り曲げ位置と、他方の側方に突出する折り曲げ位置とに変更可能にし、ハウジングのいずれか一方の側方の外面に、引き抜き時に梃子の支点になる支点凸部を設け、
可動式の雄型接触片を、真直ぐ位置にしても、真直ぐ位置から支点凸部と反対側に回転した支点凸部と反対側の折り曲げ位置にしても、雌型接触片を内蔵したコンセントに差し込み可能にし、
雄型接触片を、真直ぐ位置にしてコンセントに差し込んでも、支点凸部と反対側の折り曲げ位置にしてコンセントに差し込んでも、ハウジングを支点凸部側に回転すると、支点凸部がコンセントに当って、雄型接触片がコンセントの雌型接触片に挟まれる面積が減少して又は雄型接触片がコンセントの雌型接触片から抜け出て、雄型接触片が引き抜き易くなる構成にしたことを特徴とする雄雌嵌合式接続器。
【００１３】
２）上記の雄雌嵌合式接続器において、
ハウジングに、差込プラグを差し込む差込孔を貫通し、ハウジングの内側に、差込プラグの雄型接触片を挟む雌型接触片を設け、この雌型接触片を可動式の雄型接触片とハウジング内で電気的に接続したことを特徴とする。
【００１４】
３）上記１）の雄雌嵌合式接続器において、
上記のハウジングとは別に第２ハウジングを設け、第２ハウジングに、差込プラグを差し込む差込孔を貫通し、第２ハウジングの内側に、差込プラグの雄型接触片を挟む雌型接触片を設け、この雌型接触片を可動式の雄型接触片とコードで電気的に接続したことを特徴とする。
【００１５】
【発明の効果】
本発明の雄雌嵌合式接続器は、可動式の雄型接触片を、真直ぐ位置にしても、真直ぐ位置から支点凸部と反対側に回転した折り曲げ位置にしても、雌型接触片を内蔵したコンセントに差し込むことができる。コンセントの周囲の空間状況に応じて、雄型接触片の真直ぐ位置と折り曲げ位置とを使い分けることができる。コンセントへの差し込みが容易である。
【００１６】
その上、可動式の雄型接触片を、真直ぐ位置にしてコンセントに差し込んでも、支点凸部と反対側の折り曲げ位置にしてコンセントに差し込んでも、ハウジングを支点凸部側に回転すると、支点凸部がコンセントに当って、雄型接触片がコンセントの雌型接触片に挟まれる面積が減少して又は雄型接触片がコンセントの雌型接触片から抜け出て、雄型接触片が引き抜き易くなる。引き抜きが容易である。
【００１７】
従って、差し込みと引き抜きの両方が容易である。
【００１８】
また、本発明の雄雌嵌合式接続器は、差込プラグを差し込む差込孔と、差込プラグの雄型接触片を挟む雌型接触片を設けた場合、既存の電気器具に使用するときには、電気器具側の差込プラグを差込孔に差し込み、電源側のコンセントに可動式の雄型接触片を差し込む。電気器具側の差込プラグを取り換える手間が掛らない。実用的である。
【００１９】
【発明の実施の形態】
［第１例（図１〜図７参照）］
本例の雄雌嵌合式接続器は、図１に示すように、１対の可動式の雄型接触片７と１対の雌型接触片１１を備えている。家庭用の単相低圧電源、交流１００Ｖの電源側のコンセントと家庭用の電気器具、例えばテレビ受像機側の差込プラグとの間に使用する。
【００２０】
この接続器は、図１〜図３に示すように、殻構造の下側ハウジング１と上側ハウジング２とをネジ３で結合して、前側中央部を凹部にした箱を構成し、その凹部に可動体４を嵌め込んで、ほぼ直方体形状にしている。下側ハウジング１と上側ハウジング２及び可動体４は、電気絶縁性合成樹脂の成形品である。
【００２１】
下側ハウジング１は、下側壁の中央部上に１対の取付溝５を設け、左右の両取付溝５に、それぞれ、金属板の導電部材６の中央部を嵌合して固定し、左右の両導電部材６を前後方向に沿って設けている。
【００２２】
可動体４は、左右の側面の嵌め込み溝に、それぞれ、帯状金属板の雄型接触片７の取付用基端を嵌め込み、左右の両雄型接触片７の接触用刃部分を前方に突出している。左右の各雄型接触片７の取付用基端と左右の各導電部材６の前端は、それぞれ、重ねて電気的に接続し、枢軸８を左右方向に貫通して回転可能に連結している。可動体４とその左右の両雄型接触片７は、枢軸８の回りに上側に９０度、下側に９０度の範囲で回転可能である。
【００２３】
可動体４は、前面が前後方向と直交する平面であり、後面が枢軸８を中心軸とする半円筒面である。可動体４の左右に位置するハウジング１、２前部の右側部と左側部の前面は、枢軸８を中心軸とする半円筒面である。可動体４の前面には、１対の雄型接触片７の刃部分が左右に並列して前方に突出している。
【００２４】
１対の可動式の雄型接触片７は、取付用基端がハウジング１、２の前部に回転可能に取り付けられ、ハウジング１、２の前方に突出する真直ぐ位置から、ハウジング１、２の下側に突出する折り曲げ位置と、ハウジング１、２の上側に突出する折り曲げ位置とに変更可能である。
【００２５】
上側ハウジング２は、上側壁の前部の上面、外面に、引き抜き時に梃子の支点になる１対の支点凸部９を、可動体４の左側と右側位置に設けている。なお、支点凸部９は、上側ハウジング２の上側壁の上面にのみ設け、上側ハウジング２の前面や下側ハウジング１には設けていない。
【００２６】
導電部材６の後端は、左右からそれぞれ接触片１１を立ち上げている。左右の両接触片１１は、近接して並列し、かつ、左右方向と直交して配置し、雌型接触片の刃受け部分にしている。この雌型接触片１１の刃受け部分は、差込プラグの雄型接触片が挟み込まれる部分であり、ハウジング１、２の後側壁と対面する側が入口になり、入口側に２枚の案内片１２を外開き状に突出している。左右の両案内片１２、左右の両接触片１１と導電部材６は、一連に連結した金属板である。雌型接触片１１と可動式の雄型接触片７は、電気的に接続している。ハウジング１、２の後部内には、１対の雌型接触片１１が左右に並列して設けられている。
【００２７】
ハウジング１、２の後側壁には、１対の縦長長方形断面の差込孔１３を、１対の雌型接触片１１と対面する左右位置に、それぞれ、前後方向に沿って貫通している。１対の差込孔１３にハウジング１、２の後方位置から差込プラグの一対の雄型接触片を差し込むと、差込プラグの各雄型接触片の先端側が各雌型接触片１１に挟み込まれる。
【００２８】
本例の接続器を使用する場合、先ず、ハウジング１、２の後側面に開口する１対の差込孔１３に、図示しない家庭用電気器具のコード先端に接続した差込プラグの１対の雄型接触片を差し込む。すると、雌型接触片１１に差込プラグの雄型接触片が挟み込まれて電気的に接続される。
【００２９】
次に、ハウジング１、２の前側に突出する１対の可動式の雄型接触片７は、図４に示すように、ハウジング１、２の前方に突出する真直ぐ位置にし、家屋の壁に埋設した単相低圧電源の壁コンセントに開口する１対の差込孔２１に差し込む。すると、可動体４の前面は、壁コンセントの表面に当って重なり、１対の可動式の雄型接触片７は、それぞれ、壁コンセントに内蔵された１対の雌型接触片２２に挟み込まれ、雌型接触片２２と所定の面積ないし力で接触する。接続器は、雄型接触片７と雌型接触片１１が単相低圧電源に接続される。家庭用電気器具の差込プラグは、本例の接続器を介して単相低圧電源に接続される。
【００３０】
又は、可動式の雄型接触片７は、前方に突出する真直ぐ位置にせずに、真直ぐ位置から下側に９０度回転して、ハウジング１、２の下側、支点凸部９と反対側に突出する折り曲げ位置にし、図５に示すように、壁コンセントに開口する差込孔２１に差し込む。すると、真直ぐ位置のときと同様に、可動体４の前面は、壁コンセントの表面に当って重なり、可動式の雄型接触片７は、壁コンセントの雌型接触片２２と所定の面積ないし力で接触する。家庭用電気器具の差込プラグは、本例の接続器を介して単相低圧電源に接続される。
【００３１】
本例の接続器は、可動式の雄型接触片７を、真直ぐ位置にしても、真直ぐ位置から支点凸部９と反対側に回転した下側の折り曲げ位置にしても、壁コンセント２１、２２に差し込むことができる。
【００３２】
本例の接続器を壁コンセントから引き抜くときは、ハウジング１、２と雄型接触片７が図４に示す真直ぐ位置であっても、図５に示す折り曲げ位置であっても、ハウジング１、２の後端を片手の指で持ち上げ、ハウジング１、２を枢軸８の回りに支点凸部９側の上側に回転する。
【００３３】
すると、図６に示すように、支点凸部９が壁コンセント２１、２２の表面に当る。その後、支点凸部９が梃子の支点になり、図７に示すように、雄型接触片７が壁コンセント２１、２２から引き出され、雄型接触片７が壁コンセントの雌型接触片２２に挟まれる面積が減少して又は雄型接触片７が雌型接触片２２から抜け出て、雄型接触片７が引き抜き易くなる。本例の接続器は、片手で摘んで簡単に引き抜かれる。
【００３４】
本例の接続器は、可動式の雄型接触片７を、真直ぐ位置にして壁コンセント２１、２２に差し込んでも、真直ぐ位置から支点凸部９と反対側に回転した下側の折り曲げ位置にして壁コンセント２１、２２に差し込んでも、壁コンセント２１、２２から簡単に引き抜くことができる。
【００３５】
本例の接続器を、家屋の壁に固定した壁コンセントに差し込む場合について説明したが、タップとか、延長コードとか呼ばれる持ち運び可能な接続器具のコンセント部に差し込む場合についても、同様である。
【００３６】
［第２例（図８参照）］
本例の雄雌嵌合式接続器は、図８に示すように、差込プラグ部３１とコンセント部３２をコード３３で接続している。いわゆる延長コードである。家庭用の単相電源側のコンセントと家庭用の電気器具、例えば電熱器側の差込プラグとの間に使用する。
【００３７】
差込プラグ部３１は、第１例の接続器の前半部におけるのと同様に、第１ハウジング３４の前部に可動体４と１対の雄型接触片７を設けている。また、第１例の接続器の前半部におけるのと同様に、第１ハウジング３４の片側の外面に、引き抜き時に梃子の支点になる１対の支点凸部９を設けている。１対の可動式の雄型接触片７は、それぞれ、コード３３の１対の電線に接続している。
【００３８】
コンセント部３２は、第１例の接続器の後半部におけるのと同様に、第２ハウジング３５の後側壁に１対の差込孔１３を貫通し、第２ハウジング３５の後部に１対の雌型接触片１１を内蔵している。１対の雌型接触片１１は、それぞれ、コード３３の１対の電線に接続している。
【００３９】
本例の接続器は、第１例の接続器の前半部と後半部を差込プラグ部３１とコンセント部３２として分離し、それらをコード３３で接続したものに相当する。本例の接続器を使用する場合は、第１例の接続器におけるのと同様である。差込プラグ部３１は、第１例の接続器におけるのと同様に、壁コンセントやその他の接続器具のコンセント部に差し込み易く、また、引き抜き易い。
【００４０】
［第３例］
本例の雄雌嵌合式接続器は、第２例における差込プラグ部３１とコード３３からなる。コード３３は、一端を差込プラグ部３１に接続している。コード３３の他端には、第２例におけるコンセント部３２を接続せずに、家庭用電気器具を接続する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a technique for facilitating insertion and extraction in a male-female fitting type connector.
[0002]
[Prior art]
The insertion plug protrudes a pair of male contact pieces on the front side of the housing, and has a pair of screws connected to the pair of male contact pieces in the housing, and the pair of screws has one pair of cords. The wires are connected and the cord is pulled out to the rear of the housing.
[0003]
The movable contact plug is attached to the front part of the housing so that the proximal end of the male contact piece can be rotatably attached to the movable male contact piece. It can be changed to a bending position that protrudes to the side. This insertion plug can be inserted into an outlet containing a female contact piece regardless of whether the male contact piece is in a straight position or a bent position rotated by 90 degrees from the straight position. The straight position and the bent position of the male contact piece can be properly used depending on the space situation around the outlet. Easy to plug into outlet.
[0004]
The plug disclosed in Patent Literature 1 has a base end of a male contact piece rotatably attached to a front portion of a housing and a projection provided on both surfaces of the front portion of the housing to facilitate pulling out from an outlet. I have. This plug is inserted into an outlet with the male contact piece in a straight position protruding forward of the housing. When pulling out of the outlet, push the rear part of the housing to either side to lower the housing. Then, the projection on the side of the housing that has fallen against the surface of the outlet serves as a fulcrum of the lever, and the male contact piece easily comes off from the outlet.
[0005]
The plug disclosed in Patent Literature 2 is configured such that a base end of a male contact piece is rotatably attached to a front portion of a housing and a push-out portion is provided at a front portion of the housing so as to protrude forward so as to be easily pulled out from an outlet. I have. This plug is inserted into an outlet with the male contact piece in a bent position protruding to the side of the housing. When unplugging from the outlet, lift the back of the housing and raise the housing. Then, the push-out portion of the housing comes into contact with the surface of the outlet to serve as a fulcrum of the lever, and the male contact piece easily comes out of the outlet.
[0006]
[Patent Document 1]
Registered Utility Model No. 3010141 [Patent Document 2]
JP-A-2002-124342
[Problems to be solved by the invention]
However, a movable contact plug can be used in a straight position or a bent position depending on the space around the outlet, and it is easy to insert it into the outlet. It is hard to say that it is easy.
[0008]
The plug disclosed in Patent Literature 1 has projections on both sides of the housing that serve as fulcrum levers when the plug is pulled out, so that the male contact piece is placed at a bending position that projects to one or the other side of the housing. Then, when trying to insert it into the outlet, the protrusion on the side where the male contact piece protrudes hits the surface of the outlet and gets in the way, and the male contact piece is inserted into the female contact piece built into the outlet. Absent. If the male contact piece is in the bent position, it cannot be plugged into an outlet. This plug can only be plugged into the outlet when the male contact piece is in a straight position protruding forward of the housing. It is hard to say that it is easy to insert.
[0009]
In the insertion plug disclosed in Patent Document 2, the push-out portion, which serves as a fulcrum of a lever when being pulled out, protrudes forward of the housing. If the user tries to insert the plug into the outlet, the pusher contacts the surface of the outlet and gets in the way, so that the male contact piece is not inserted into the female contact piece built into the outlet. If the male contact piece is in a straight position, it cannot be plugged into an outlet. This plug can only be inserted into the outlet when the male contact piece is in a bent position protruding on one or the other side of the housing. It is hard to say that it is easy to insert.
[0010]
Therefore, it is hard to say that these plugs are easy to insert and pull out.
[0011]
In addition, since these plugs are configured to connect the electric wire of the cord to the screw in the housing, when using it for an existing electric appliance, remove the existing plug connected to the cord of the electric appliance. , You will connect a new plug to that cord. It takes time and effort to replace the plugs of electrical appliances.
[0012]
[Means for Solving the Problems]

To a bending position that protrudes toward the other side, and a fulcrum convex part that becomes a fulcrum of a lever when pulled out is provided on one of the lateral outer surfaces of the housing,
Whether the movable male contact piece is in a straight position or in a bent position on the opposite side of the fulcrum that has been rotated from the straight position to the opposite side of the fulcrum, insert the female contact piece into an outlet with a built-in female contact. Make it possible
Even if the male contact piece is inserted straight into the outlet, or inserted into the outlet at the bending position opposite to the fulcrum, when the housing is rotated to the fulcrum, the fulcrum hits the outlet, The contact area between the male contact piece and the female contact piece of the outlet is reduced, or the male contact piece comes off from the female contact piece of the outlet so that the male contact piece can be easily pulled out. Male-female connector.
[0013]
2) In the above male-female fitting type connector,
A female contact piece is provided in the housing through the insertion hole for inserting the insertion plug, and a female contact piece sandwiching the male contact piece of the insertion plug is provided inside the housing. The female contact piece is a movable male contact piece. And electrically connected within the housing.
[0014]
3) In the male-female fitting type connector of the above 1),
A second housing is provided separately from the above-mentioned housing, and a female contact piece which penetrates the insertion hole for inserting the insertion plug in the second housing and which holds the male contact piece of the insertion plug inside the second housing. And the female contact piece is electrically connected to the movable male contact piece by a cord.
[0015]
【The invention's effect】
The male-female fitting connector according to the present invention incorporates the female contact piece even when the movable male contact piece is in a straight position or in a bent position rotated from the straight position to the opposite side of the fulcrum convex portion. Can be plugged into an outlet. The straight position and the bent position of the male contact piece can be properly used depending on the space situation around the outlet. Easy to plug into outlet.
[0016]
In addition, even if the movable male contact piece is inserted straight into the outlet, or inserted into the outlet at the bending position opposite to the fulcrum projection, when the housing is rotated toward the fulcrum projection, the fulcrum projection is formed. Hits the outlet, and the area where the male contact piece is sandwiched between the female contact pieces of the outlet is reduced, or the male contact piece comes off from the female contact piece of the outlet, and the male contact piece is easily pulled out. Easy to pull out.
[0017]
Therefore, both insertion and extraction are easy.
[0018]
Further, when the male-female fitting type connector of the present invention is provided with an insertion hole into which an insertion plug is inserted and a female contact piece sandwiching the male contact piece of the insertion plug, when used for existing electric equipment, Then, insert the insertion plug on the side of the electric appliance into the insertion hole, and insert the movable male contact piece into the outlet on the power supply side.
