【００１７】
【発明の実施の形態】
以下、本発明に係る接続端子であるリード線どうしを接続する第１の実施の形態を図１〜図３と共に説明する。
１は燐青銅等の導電性材料をプレス加工によって作製した雄端子にして、一端にリード線３の銅線部を挟持圧着する圧着部１１、該圧着部１１から延長された首部１２および該首部１２から延長され先端に向かって幅が広く形成された雄接続部１３から構成されている。なお、雄接続部１３の略中央には長孔１３ａが形成されている。
【００１８】
２は前記雄端子と同様な材料をプレス加工によって作製した雌端子にして、一端にリード線３の銅線部を挟持圧着する圧着部２１、該圧着部２１から延長された首部２２および該首部２２から延長され先端に向かって幅が狭く形成された平坦部２３ａと、該平坦部２３ａの両側縁から上縁側が狭くなるように起立された一対の起立片２３ｂとが一体的に形成された雌接続部２３から形成されている。
【００１９】
なお、前記平坦部２３ａの略中央には前記雄端子１の長孔１３ａに係合される爪片２３ｃが形成されている。また、一対の起立片２３ｂにおける幅の狭い先端側の幅は、前記雄端子１の首部１２の幅より若干広く形成されている。
【００２０】
次に、前記した構成の接続端子を利用してリード線３どうしを接続する方法について説明する。
先ず、雄端子１の首部１２を雌端子２の起立片２３ｂの開放側から差し込み（図２参照）、同図において互いに離れる方向に引っ張ることで、雄接続部１３が雌接続部２３の起立片２３ｂの間に位置する。この時、起立片２３ｂの開放側の幅が狭くなっているので、雄接続部１３が起立片２３ｂに嵌まり込むにしたがって平坦部２３ａ側に押し付けられる。
【００２１】
そして、雄接続部１３が起立片２３ｂの間に移動した状態において爪片２３ｃが長孔１３ａ内に入り込みロックされた状態となるので、振動や衝撃に対して雄端子１と雌端子２とは離れることがなくなる（図３参照）。なお、雄端子１と雌端子２とを分離させるには、爪片２３ｃをドライバー等によって下方に押し下げた状態で、雄端子１を雌端子２側に移動させることにより行える。
【００２２】
前記した実施の形態にあっては、長孔１３ａと爪片２３ｃとの係合によって雄端子１と雌端子２とを一体化した場合について説明したが、長孔１３ａと爪片２３ｃとのロック手段は必ずしも必要ではなく、雄接続部１３と起立片２３ｂとの摩擦のみによって接続してもよい。また、雄接続部１３の起立片２３ｂと接触する側面に摩擦係数を高めるための鋸歯を形成し、一方、起立片２３ｂの内面側にも鋸歯を形成し、両鋸歯どうしを噛み合わせることによりズレを防止するようにしてもよい。
【００２３】
次に、第２の実施の形態を図４〜図７と共に説明する。なお、前記した実施の形態と同一符号は同一部分を示し説明は省略する。
この実施の形態にあっては、前記ロックするための雄端子１に形成した長孔１３ａに変えて雄接続部１３の先端に起立片１３ｂを形成したこと、また、雌端子２の爪片２３ｃに変えて前記首部２２の位置に前記起立片２３ｂと若干の間隔（雄端子１の材厚分の間隔）を介して一対の折曲片２２ａを形成したことである。なお、一対の折曲片２２ａの間隔は雄接続部１３の最大幅よりも広く形成されている。
【００２４】
このように構成した本実施の形態においても、前記した第１の実施の形態と同様に、雄接続部１３を雌接続部２２の起立片２３ｂに係合させた状態で（図６参照）、図７に示すように、折曲片２２ａを内側に折曲することで雄接続部１３の起立片１３ｂが起立片２３ｂと折曲片２２ａとの間に挟持されてロック状態となり、従って、一対の折曲片２２ａの間隔を広げない限り雄端子１と雌端子２とは外れることがなくなる。
【００２５】
次に、第３の実施の形態を図８、図９と共に説明する。なお、前記した第２の実施の形態と同一符号は同一部分を示し説明は省略する。
この実施の形態においては、雄端子１は前記第２の実施の形態と同じものであるが、雌端子２は折曲部２２ａを無くした構造である。
【００２６】
そして、この実施の形態は前記第２の実施の形態と同様に雄端子１の雄接続部１３を雌端子２の起立片２３に係合すると、該係合時において爪片２２ｂを乗り越えて係合が行われ、その結果、起立片１３ｂの表面側に爪片２２ｂが位置するようになる。従って、雄端子１は雌端子２に対してロック状態となり、振動や衝撃によって外れることがなくなる。
【００２７】
前記した実施の形態はリード線どうしの接続の場合であるが、プリント基板に半田付け固定された端子ブロックの場合について図１０と共に説明する。なお、前記した実施の形態と同一符号は同一部分を示し説明は省略する。
この実施の形態にあっては、前記した第１の実施の形態における雌端子２の圧着部２１を形成せずに、首部２２の延長部分を折曲して埋設部２４を形成すると共に埋設部２４の両側面に鋸歯部２４ａを形成し、また、埋設部２４の先端をプリント基板の導電パターンに接続するための差し込み部２４ｂを一体に形成したものである。
【００２８】
そして、前記埋設部２４を合成樹脂で形成されたブロック４の孔（図示セズ）に差し込んで固定することにより、端子ブロックが形成される。なお、前記埋設部２４をブロックに差し込んだ状態において、鋸歯部２４ａがブロック４の孔に引っ掛かるために、雌端子２がブロック４から抜け出ることなく固定される。
【００２９】
このように構成された端子ブロックは、前記差し込み部２４ｂをプリント基板の導電パターンの部分に形成されている孔に挿入し半田付けして固定される。そして、ブロック４に固定されている雌端子２に対して前記した第１の実施の形態と同様に雄端子１を係合することにより、雄端子１に取付けられているリード線３は雌端子２を介してプリント基板の導電パターンに電気的に接続される。
【００３０】
なお、前記した実施の形態にあっては、雌端子２をブロック４に固定したものを示したが、雄端子１の圧着部１１を無くして首部１２を延長して前記したと同様な埋設部を形成して雄端子１をブロック４に固定し、一方、雌端子を前記第１の実施の形態におけるリード線３が接続された雌端子をそのまま利用することで、雄端子と雌端子を逆の状態とすることもできる。
【００３１】
次に、電子機器に固定され、リード線どうしを接続するための中継端子ブロックの一実施の形態を図１１と共に説明する。なお、前記した実施の形態と同一符号は同一部分を示し説明は省略する。
１枚の導電性基板５１の両端に前記した実施の形態における起立片２３ｂと同じ役目をする起立片５２を切り起こして形成すると共に前記爪片２３ｃも同様にして前記起立片５２の間に爪片５２も切り起こして雌端子５としたものである。そして、前記導電性基板５１の側面から鋸歯５４ａを有する埋設部５４を一体的に形成し、この埋設部５４を利用してブロック４に固定して中継端子ブロックとしたものである。
【００３２】
このように構成した中継端子ブロックにあっては、雌端子５の両端に形成された起立片５２に前記した第１の実施の形態と同様に雄端子１を係合すると共に雄端子１に形成されている長孔１３ａに爪片５２を嵌め込むことにより、一対のリード線３はブロック４上に固定された雌端子５を介して接続することができる。
【００３３】
前記した図１１の実施の形態のものは、雌端子５をブロック４に固定した場合の説明であるが、雄端子６をブロック４に固定しても前記したと同様にリード線３どうしを、雄端子６を利用して電気的に接続することができる。以下、この実施の形態を図１２と共に説明する。
【００３４】
雄端子６は導電性基板６１の側面から下方に延長された埋設部６２を利用してブロック４に固定し、前記導電性基板６１の両端から前記した第１の実施の形態と同様な首部６３を介して雄接続部６４を形成すると共に雄接続部６４の部分に長孔６４ａを形成することで中継端子ブロックとしたものである。
【００３５】
一方、雌端子としては、前記した第１の実施の形態における雌端子２を一対用意し、この雌端子２を両端に雄接続部６４を有する雄端子６に前記した第１の実施の形態と同じ作業を行うことで係合固定することで、一対のリード線３は雄端子６によって電気的に接続することができる。
【００３６】
なお、前記した第２および第３の実施の形態を除いて、雌端子２に爪片２３ｃを形成し、あるいは雌端子５に爪片５３を形成し、この爪片２３ｃ，５３に雄端子１あるいは６の長孔１３ａ，６４ａを係合する場合を示したが、雄端子１，６側に爪片を形成し、雌端子２，５側に長孔を形成したものであってもよい。
【００３７】
【発明の効果】
本発明は前記したように、リード線が接続される圧着部の先端に、先端に向かって幅が狭くなる平坦部を形成すると共に、該平坦部の両側から開放面側の幅が狭くなるように起立片が形成された雌端子と、リード線が接続された圧着部の先端に、前記平坦部と同形状に形成された雄接続部を形成した雄端子とから構成し、前記雄端子の雄接続部を雌端子の起立片の間に差し込んで互いに引っ張ることで両者が摩擦によって係合固定されるので、簡単な構造でリード線どうしを確実に接続することができる。
【００３８】
また、前記雌端子に爪片あるいは長孔の何れかを形成し、また、前記雌端子の雌接続部に前記雄端子の雄接続部を係合した状態において、前記雌端子の爪片あるいは長孔に係合される長孔あるいは爪片を形成したので、爪片と長孔との係合により雄端子と雌端子との係合状態がより確実に行われ、また、両者を分離するには爪片を押し下げながら端子を引っ張ることで簡単に行えるものである。
【００３９】
さらに、前記した構造の雄端子あるいは雌端子をブロックに固定することで端子ブロックとしての利用が行え、また、前記雄端子あるいは雌端子の何れかをブロックの両端に固定形成することで中継端子ブロックとしての利用も行える等の効果を有するものである。

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a first embodiment for connecting lead wires as connection terminals according to the present invention will be described with reference to FIGS.
Reference numeral 1 denotes a male terminal made of a conductive material such as phosphor bronze by press working, a crimping portion 11 for holding and crimping a copper wire portion of the lead wire 3 at one end, a neck portion 12 extended from the crimping portion 11, and the neck portion. The male connecting portion 13 is extended from the second connecting portion 12 and has a width increasing toward the distal end. It should be noted that a long hole 13a is formed substantially at the center of the male connection portion 13.
[0018]
Reference numeral 2 denotes a female terminal made of the same material as the male terminal by press working, and a crimping portion 21 for holding and crimping the copper wire portion of the lead wire 3 at one end, a neck portion 22 extended from the crimping portion 21, and the neck portion. A flat portion 23a which extends from 22 and is formed narrower toward the front end, and a pair of upright pieces 23b which are erected from both side edges of the flat portion 23a so that the upper edge side becomes narrower are integrally formed. The female connecting portion 23 is formed.

It should be noted that a claw piece 23c to be engaged with the elongated hole 13a of the male terminal 1 is formed substantially at the center of the flat portion 23a. Further, the width of the pair of upright pieces 23b on the narrower end side is formed to be slightly wider than the width of the neck 12 of the male terminal 1.
[0020]
Next, a method of connecting the lead wires 3 using the connection terminals having the above-described configuration will be described.
First, the neck portion 12 of the male terminal 1 is inserted from the open side of the standing piece 23b of the female terminal 2 (see FIG. 2), and is pulled away from each other in FIG. 23b. At this time, since the width of the upright piece 23b on the open side is narrow, the male connection portion 13 is pressed against the flat portion 23a as it fits into the upright piece 23b.
[0021]
Then, when the male connecting portion 13 is moved between the upstanding pieces 23b, the claw pieces 23c enter the elongated holes 13a and become locked, so that the male terminal 1 and the female terminal 2 are not affected by vibration or impact. No separation (see FIG. 3). The male terminal 1 and the female terminal 2 can be separated by moving the male terminal 1 toward the female terminal 2 with the claw pieces 23c pressed down by a driver or the like.
