Description

【０００１】
【発明の属する技術分野】
本発明は、二つの導体を重ねて接続する接続端子に関するものである。
【０００２】
【従来の技術】
従来のこの種の接続端子Ａ′としては、図１６に示すように１枚のバネ性のある板材を屈曲して一体に形成したものがある。つまり、縦片ａと横片ｂと斜片ｃを有するように略直角三角形状に曲げてあり、縦片ａに設けた角孔ｄに横片ｂの先端の突片ｅを摺動自在に挿通してある。角孔ｄの下縁は鎖錠部ｆとなっており、突片ｅと鎖錠部ｆとの間に導体を挟持するようになっている。つまり、図１７に示す矢印のように押圧して変形させると、突片ｅと鎖錠部ｆとが離れて入線スペースＳが確保され、突片ｅと鎖錠部ｆとの間に一対の導体を差し込んで離すと、バネ性にて一対の導体が挟持されて接続されるようになっている。
【０００３】
【発明が解決しようとする課題】
ところが、上記構造の接続端子Ａ′では図１８（ａ）のように向けた状態で矢印のようにドライバーで押したときには横片ｂを支えなければ突片ｅと鎖錠部ｆとの間に隙間ができるように変形させることができないが、図１８（ａ）の符号ｇに示す部分には導体が入るためにこの部分で横片ｂを支えることができない。このため横片ｂを支えるためには特別なハウジングが必要になり、接続端子Ａ′単体では接続することができず、接続装置が大型になるという問題がある。また接続端子Ａ′の向きを変えて図１８（ｂ）に示すように斜片ｃを机や台等の基台ｈに載せ、突片ｅをドライバー等で矢印の方向に押して突片ｅと鎖錠部ｆとの間に間隔をあけて入線スペースＳを確保した場合、導体の差し込まれる箇所とドライバーで押す箇所が重なるために結線の邪魔になって結線作業がしにくいという問題がある。また上記の接続端子Ａ′では図１８（ｃ）のように導体１を挟持して保持する箇所が１箇所しかなく、可撓性を有する導体１を接続する場合は導体接触部が一直線上のみになることがあって接続の信頼性が低いという問題がある。
【０００４】
本発明は上記問題点に鑑みてなされたものであって、本発明は簡単な操作で入線スペースを確保し、導体の入線も容易にし、接続作業を容易にすることを課題とする。
【０００５】
【課題を解決するための手段】
上記課題を解決するために本発明接続端子Ａは、１枚のバネ性のある板材を屈曲して一体に形成される接続端子であって、対向する固定片２と可動片３の一端を自由端とすると共に固定片２と可動片３の他端間を円弧状の連結バネ部４で一体に繋ぎ、固定片２の自由端の幅方向の両側から可動片３を跨ぐように一対の連出片５を連出し、連出片５の先端同士を連結部６で一体に連結し、連結部６に可動片３と対向する鎖錠部７を設けると共に可動片３と鎖錠部７との間を導体挟持部とし、固定片２及び可動片３の自由端側の連出片５より自由端方向に突出する部分をラジオペンチの掴み代とし、可動片３の両側から固定片２と反対側に突出する押圧片１７を連出して成ることを特徴とする。このように構成された接続端子Ａは、固定片２や可動片３の自由端側の掴み代をラジオペンチ８で掴んで可動片３を固定片２側に撓み変形させることで可動片３と鎖錠部７との間に間隔をあけて入線スペースＳを確保し、可動片３と鎖錠部７との間に導体１を挿入してラジオペンチ８を離すことにより、可動片３と鎖錠部７との間に導体１を挟持して導体１を接続できる。また机や台等の基台３３の上に固定片２を載せるように接続端子Ａを配置し、専用工具３０の両側片を押圧片１７に当接し、専用工具３０にて押圧片１７を押して可動片３を撓ませて鎖錠部７と可動片２との間に隙間をあけて入線スペースＳを確保し、可動片３と鎖錠部７との間に導体１を挿入して専用工具３０を離すことにより可動片３と鎖錠部７との間に導体１を挟持して導体１を接続できる。これにより接続端子Ａ単体で導体１の接続ができて接続装置が大型になったりしなく、また入線スペースＳをあけて接続するときラジオペンチ８や専用工具３０のような工具が導体１の入線の邪魔になることがなく、接続作業が容易にできる。
【０００６】
また連結部６に接触面積を増やすための曲げ部９を一体に設けて成ることを特徴とすることも好ましい。この場合、鎖錠部７と曲げ部９を導体１に接触させることができ、可撓性のある導体１でも接続の信頼性を向上できる。
また可動片３の鎖錠部７側の面にローレット面１０を設けて成ることを特徴とすることも好ましい。この場合、ローレット面１０で摩擦を持たせて導体１のずれを防止できる。
【０００７】
さらに可動片３に導体１の端子を位置決めする位置決め穴１１を設けて成ることを特徴とすることも好ましい。この場合、導体１の端子に突起を設けておけば、突起を位置決め穴１１に嵌合して導体１の位置決めができる。
また本発明の他の接続端子Ａは１枚のバネ性のある板材を屈曲して一体に形成される接続端子であって、対向する固定片２と可動片３の一端を自由端とすると共に固定片２と可動片３の他端間を円弧状の連結バネ部４で一体に繋ぎ、固定片２の自由端側及び連結バネ部４側から夫々可動片３を跨ぐように夫々連出片５を連出し、可動片３の両側で夫々自由端側の連出片５と連結バネ部４側の連出片５とを連結部６で連結し、連結部６に可動片３と対向する鎖錠部７を設けると共に可動片３と鎖錠部７との間を導体挟持部とし、可動片３の両側に突出部３１を側方に突出するように突設し、可動片３の自由端側の端部から固定片２と反対側に略垂直に突出するように突片１２を突設して成ることを特徴とする。このように構成された接続端子Ａは、机や台等の基台３３に固定片２を載せるように接続端子Ａを配置し、突片１２にてマイナスドライバー３２の先端をガイドしてマイナスドライバー３２の先端を可動片３の自由端に当接し、マイナスドライバー３２で可動片３を押して可動片３が固定片２に近接するように撓み変形させて可動片３と鎖錠部７との間に間隔をあけて入線スペースＳを確保し、可動片３と鎖錠部７との間に導体１を挿入してマイナスドライバー３２を離すことにより可動片３と鎖錠部７との間に導体１を挟持して導体１を接続できる。また固定片２の自由端側と可動片３の突片１２との間をラジオペンチ８で挟持して可動片３を撓ませて鎖錠部７と可動片３との間に間隔をあけて入線スペースＳを確保し、鎖錠部７と可動片３との間に導体１を挿入してラジオペンチ８を離すことにより可動片３と鎖錠部７との間に導体１を挟持して導体１を接続できる。これにより接続端子Ａ単体で導体１の接続ができて接続装置が大型になったりしなく、また入線スペースＳをあけて接続するときマイナスドライバー３２やラジオペンチ８のような工具が導体１の入線の邪魔になることがなく、接続作業が容易にできる。しかも、鎖錠部７が可動片３の両側にあるため導体１を２箇所で挟持して接続の信頼性を向上できる。
【０００８】
上記の構造の接続端子でも、可動片３の鎖錠部７側の面にローレット面１０を設けて成ることを特徴とすることも好ましく、また可動片３に導体１の端子を位置決めする位置決め穴１１を設けて成ることを特徴とすることも好ましい。
また可動片３の先端から固定片２と反対側に向けて突片１２を突設し、突片１２の先端から可動片３と略平行になるように補助保持片１３を連出して成ることを特徴とすることも好ましい。この場合、導体１を可動片３と鎖錠部７との間に挟持した状態で導体１を補助保持片１３でも保持できて導体１を安定よく保持することができる。
【０００９】
【発明の実施の形態】
まず図１に示す接続端子Ａの例から述べる。接続端子Ａはバネ性のある１枚の金属板を一体に折曲して形成してある。固定片２と可動片３とは対向するように配置してあり、固定片２と可動片３の一端は自由端となり、固定片２と可動片３の他端間は円弧状の連結バネ部４にて一体に繋いである。固定片２の自由端側の両側から可動片３を跨ぐように夫々連出片５を連出してあり、連出片５の先端同士を連結部６で一体に連結してある。連結部６から断面略し字状の突片部１４を突設してあり、突片部１４の先端に鎖錠部７を設けてある。また突片部１４の基部側には導体１に接触する曲げ部９を設けてある。固定片２や可動片３の連出片５より突出する部分はラジオペンチ８の掴み代となっている、可動片３の掴み代の先端には固定片２側に向けて傾斜せる傾斜部１５を設けてあり、傾斜部１５の先端には滑り止め屈曲部１６を設けてある。また可動片３の両側から夫々固定片２と反対側に突出する押圧片１７を突設してある。また可動片３が連結バネ部４のバネ性で鎖錠部７に当接している状態で、可動片３の長手方向と平行な線に対して固定片２が広がるようにαの角度傾斜している。
【００１０】
次に上記のように構成せる接続端子Ａを用いて１対の導体１を接続する仕方を説明する。工具としてラジオペンチ８を用いて操作する例から述べる。図２（ａ）に示すように固定片２や可動片３の自由端側の掴み代をラジオペンチ８で掴んで、可動片３が固定片２に近接するように撓み変形させ、可動片３と鎖錠部７との間に間隔をあけて入線スペースＳを確保する。そして一対の導体１を可動片３と鎖錠部７との間に差し込んでラジオペンチ８を離す。すると、可動片３と鎖錠部７との間に図２（ｂ）に示すようにバネ性にて一対の導体１が挟持されて一対の導体１が接続される。このとき鎖錠部７と可動片３との間に導体１が挟持されるだけでなく、曲げ部９が導体１に当接されて、曲げ部９と可動片３との間でも導体１が挟持されて接続の信頼性が向上する。またラジオペンチ８で掴むとき、可動片３の先端に傾斜部１５を設けてあるために、ラジオペンチ８が導体１の入線の邪魔にならない。また傾斜部１５が設けてあっても、傾斜部１５の先端に滑り止め屈曲部１６を設けてあるためにラジオペンチ８が滑って外れるという弊害を生じない。また固定片２がαの角度傾斜しているためにラジオペンチ８で撓ませるとき変位をかせぐことでき、導体１の板厚が薄くても強い挟み力を得ることができる。また工具としてコ字状の専用工具３０を用いる場合について説明する。この場合、机や台等の基台３３の上に固定片２を載せるように接続端子Ａを配置し、専用工具３０の両側片を図３（ａ）のように押圧片１７に当接し、専用工具３０にて押圧片１７を押して可動片２を撓ませて鎖錠部７と可動片３との間に隙間をあけて入線スペースＳをあけ、鎖錠部７と可動片３との間に一対の導体１を挿入して専用工具３０による押圧を解除し、可動片３と鎖錠部７や曲げ部９との間に導体１を挟持する。
【００１１】
図４や図５は上記接続端子Ａを用いて導体１を接続するリレーユニットの構造を示すものである。リレー１８から一方の導体１としての端子１ａを突設してあり、他方の導体１としての編組銅線１ｂの一端と端子１ａとを重ねて接続端子Ａにて上記のように接続してある。また編組銅線１ｂの他端を端子板１９とも接続端子Ａで接続してある。さらに図中、２０，２１はリレーを収納するケース、２２は端子板１９の端子ねじ、２３は端子板１９の座金、２４は隔壁、２５はプリント板、２６は端子板、２７は座金、２８は端子ねじ、２９は隔壁である。
【００１２】
図６、図７は図１の接続端子Ａにさらに改良を加えた例を示す。図６に示すものは可動片３の鎖錠部７側の面の全面にローレット面１０を施してある。このようにしてあると、導体１を接続したとき導体１が滑るのを防止できる。また図７に示すものは可動片３に位置決め穴１１を設けてある。この場合、導体１の端子等に突起を設けておけば、突起を位置決め穴１１に嵌合することで導体１を位置決めできる。
【００１３】
次に図８に示す他の接続端子Ａについて述べる。この接続端子Ａもバネ性のある１枚の金属板を一体に折曲して形成してある。固定片２と可動片３とは対向するように配置してあり、固定片２と可動片３の一端は自由端となり、固定片２と可動片３の他端間は円弧状の連結バネ部４にて一体に繋いである。固定片２の両側の自由端側及び連結バネ部４側の両側から可動片３を跨ぐように連出片５を連出してあり、夫々の両側で自由端側の連出片５と連結バネ部４側の連出片５とを連結部６で一体に連結してあり、連結部６の可動片３に対向する部分を鎖錠部７としてある。また可動片３の両側には突出部３１を側方に突出するように突設してある。可動片３の自由端側の端部から固定片２と反対側に略垂直に突出するように突片１２を突設してある。また可動片３の突出部３１が連結バネ部４のバネ性で鎖錠部７に当接している状態で、可動片３の長手方向と平行な線に対して固定片２が広がるようにαの角度傾斜している。
【００１４】
次に上記のように構成せる接続端子Ａを用いて１対の導体１を接続する仕方を説明する。工具としてマイナスドライバー３２を用いて操作する例から述べる。図９（ａ）に示すように机や台等の基台３３に固定片２を載せるように接続端子Ａを配置し、マイナスドライバー３２の先端を可動片３の自由端に当接し、マイナスドライバー３２で可動片３を押して可動片３が固定片２に近接するように撓み変形させ、可動片３と鎖錠部７との間に間隔をあけて図９（ｂ）に示すように入線スペースＳを確保する。マイナスドライバー３２で可動片３を押すとき突片１２があるために突片１２にてマイナスドライバー３２の先端をガイドでき、マイナスドライバー３２による操作が安定して作業しやすい。入線スペースＳを確保した後、一対の導体１を可動片３と鎖錠部７との間に差し込んでマイナスドライバー３２による押圧を解除する。すると、可動片３と鎖錠部７との間に図９（ｃ）に示すようにバネ性にて一対の導体１が挟持されて一対の導体１が接続される。このとき両側の鎖錠部７と可動片３との間に導体１が挟持されるので、２箇所で導体１が挟持されて接続の信頼性が向上する。また固定片２がαの角度傾斜しているためにマイナスドライバー３２で撓ませるとき変位をかせぐことでき、導体１の板厚が薄くても強い挟み力を得ることができる。また工具としてラジオペンチ８を用いる場合について説明する。固定片２の自由端側と可動片３の突片１２との間をラジオペンチ８で挟持し、可動片３を撓ませて鎖錠部７と可動片３との間に隙間をあけて図１０に示すように入線スペースＳをあけ、鎖錠部７と可動片３との間に一対の導体１を挿入してラジオペンチ８による挟持を解除し、可動片３と鎖錠部７との間に導体１を挟持する。
【００１５】
図１１や図１２は上記接続端子Ａを用いて導体１を接続するリレーユニットの構造を示すものである。これは接続端子Ａの構造が異なるだけで他の部分は図４、図５に示すものと同じであるために、図面に同様の符号を付して説明は省略する。
図１３、図１４、図１５は図８の接続端子Ａにさらに改良を加えた例を示す。図１３に示すものは可動片３の鎖錠部７側の面の全面にローレット面１０を施してあり、導体１を接続したとき導体１が滑るのを防止するようにしてある。図１４に示すものは可動片３に位置決め穴１１を設けてあり、導体１の端子の突起を位置決め穴１１に嵌合することで導体１の位置決めができるようになっている。図１５に示すものは可動片３の突片１２の先端から可動片３と平行になるように補助保持片１３を連出してある。この場合、鎖錠部７と可動片３との間に導体１を挟持した状態で補助保持片１３にて導体１を保持できるようになっており、導体１を安定よく保持できるようになっている。

As a conventional connection terminal A 'of this type, there is a connection terminal formed by bending a single spring-like plate material and integrally forming the same as shown in FIG. That is, it is bent into a substantially right triangle so as to have the vertical piece a, the horizontal piece b, and the oblique piece c, and the protruding piece e at the tip of the horizontal piece b is slidably inserted into the square hole d provided in the vertical piece a. It is inserted. The lower edge of the square hole d is a lock portion f, and a conductor is sandwiched between the protruding piece e and the lock portion f. That is, when pressed and deformed as shown by the arrow shown in FIG. 17, the projecting piece e and the locking portion f are separated from each other to secure the entry space S, and a pair of When a conductor is inserted and separated, a pair of conductors is sandwiched and connected by spring properties.
[0003]
[Problems to be solved by the invention]
However, in the connection terminal A 'having the above structure, when the horizontal piece b is not supported when pushed by a screwdriver as shown by an arrow in a state as shown in FIG. Although it cannot be deformed so as to form a gap, the horizontal piece b cannot be supported at the portion indicated by reference numeral g in FIG. Therefore, a special housing is required to support the horizontal piece b, and the connection terminal A 'cannot be connected by itself, and there is a problem that the connection device becomes large. Also, as shown in FIG. 18 (b), the direction of the connection terminal A 'is changed, the oblique piece c is placed on a base h such as a desk or a table, and the protruding piece e is pushed in the direction of the arrow with a screwdriver or the like to thereby form In the case where the insertion space S is secured with an interval between the locking portion f and the location where the conductor is inserted and the location where the conductor is pressed by the driver overlap, there is a problem that the connection is obstructed and the connection work is difficult. Also, in the connection terminal A ', there is only one place where the conductor 1 is sandwiched and held as shown in FIG. 18 (c), and when the flexible conductor 1 is connected, the conductor contact portion is only on a straight line. And the reliability of the connection is low.
[0004]
The present invention has been made in view of the above problems, and it is an object of the present invention to secure an input space with a simple operation, facilitate the insertion of a conductor, and facilitate a connection operation.
[0005]
[Means for Solving the Problems]
In order to solve the above problem, the connection terminal A of the present invention is a connection terminal formed by bending a single springy plate material and integrally forming one end of the fixed piece 2 and the movable piece 3 facing each other. The fixed piece 2 and the other end of the movable piece 3 are integrally connected with each other by an arc-shaped connecting spring portion 4, and a pair of connecting members are arranged so as to straddle the movable piece 3 from both sides in the width direction of the free end of the fixed piece 2. The projecting piece 5 is extended, the leading ends of the extending pieces 5 are integrally connected with each other by a connecting portion 6, and the connecting portion 6 is provided with a locking portion 7 facing the movable piece 3, and the movable piece 3 and the locking portion 7 are connected to each other. Between the fixed piece 2 and the movable piece 3 at the free end side of the movable piece 3 and projecting in the free end direction is used as a grip for radio pliers. It is characterized in that the pressing piece 17 protruding to the opposite side is continuously extended . The connection terminal A configured as described above is configured such that the gripping margin on the free end side of the fixed piece 2 or the movable piece 3 is gripped by the radio pliers 8 and the movable piece 3 is flexed and deformed toward the fixed piece 2 to form the movable terminal 3 with the movable piece 3. A space is secured between the movable piece 3 and the lock part 7 to secure the input space S, the conductor 1 is inserted between the movable piece 3 and the lock part 7, and the pliers 8 are released. The conductor 1 can be connected to the lock 7 by sandwiching the conductor 1. In addition, the connection terminal A is arranged so that the fixed piece 2 is placed on a base 33 such as a desk or a table, and both side pieces of the special tool 30 are brought into contact with the pressing piece 17, and the pressing piece 17 is pressed by the special tool 30. The movable piece 3 is deflected to secure a space S between the lock 7 and the movable piece 2 to secure a wire entry space, and the conductor 1 is inserted between the movable piece 3 and the lock 7 to use a special tool. By separating the conductor 30, the conductor 1 can be sandwiched between the movable piece 3 and the lock portion 7, and the conductor 1 can be connected. As a result, the conductor 1 can be connected by the connection terminal A alone, so that the connection device does not become large, and when the connection is made with the insertion space S open, a tool such as the pliers 8 or the special tool 30 is used to insert the conductor 1 into the conductor 1. Connection work can be easily performed without disturbing the connection.
