Description

接続端子
　本発明は、接続端子に関する。
　従来例の接続端子として、タブ状の相手接続部が挿入される箱状の電気接続部を有し、電気接続部が内部に複数の接触部を有したものが知られている（特許文献１参照）。
　この従来例の接続端子では、箱状に形成されたケースに配置された接続片に対して、主接触片と補助接触片とが別体で形成され、接続片と主接触片と補助接触片とが固定部材を介して一体に固定されている。
実開昭５５－５１７３１号公報(JP S55-051731 U)
　特許文献１のような従来の接続端子では、相手接続部と接触部との接触点を４点とすることによって、相手接続部と接触部との接触点が２点である場合に比較して、相手接続部と接触部との接触における回路抵抗を低減することができる。
　しかしながら、特許文献１のような従来の接続端子では、電気接続部において、接続片と主接触片と補助接触片とが別体で形成されているので、部品点数が増加していた。加えて、別体で形成された接続片と主接触片と補助接触片とを一体に固定することにより、電気接続部における回路抵抗が増加してしまっていた。
　そこで、この発明は、部品点数を削減でき、回路抵抗を低減することができる接続端子の提供を目的としている。
　本発明の第１の特徴に係る接続端子は、タブ状の相手接続部が挿入される箱状の電気接続部を備える。電気接続部は、内部に連続する一部材で形成され、相手接続部と接触される複数の接触部を備える。複数の接触部は、相手接続部の挿入方向上流側に設けられ相手接続部を狭持して接触する一対の第１接触部と、相手接続部の挿入方向下流側に設けられ相手接続部を狭持して接触する一対の第２接触部とを備える。
　本発明の第１の特徴に係る接続端子では、電気接続部が内部に連続する一部材で形成され相手接続部と接触される複数の接触部を備えるため、複数の接触部を別体で形成させる必要がなく、部品点数を削減することができる。加えて、電気接続部における回路抵抗を低減することができる。
　従って、本発明の第１の特徴に係る接続端子では、複数の接触部が電気接続部で連続する一部材で形成されているので、部品点数を削減でき、回路抵抗を低減することができる。
　また、複数の接触部は、相手接続部の挿入方向上流側に設けられた一対の第１接触部と、相手接続部の挿入方向下流側に設けられた一対の第２接触部とを備えるため、相手接続部と接続端子との材料の種類によって電流が流れるメイン流路として第１接触部と第２接触部とのうちのいずれか一方を選択することができる。
　このため、相手接続部及び接続端子の形状を変更することなく、相手接続部と接続端子との間を流れる電流の回路長を変更することができる。
　複数の接触部は、一対の第１接触部と一対の第２接触部との間に設けられ、相手接続部に接触する第３接触部を備えていることが好ましい。
　このような構成により、複数の接触部は、相手接続部に対し、５点の接触点を有することとなり、さらに回路抵抗を低減することができる。
　本発明の第１の特徴に係る接続端子は相手接続部の挿入により弾性変形可能な弾性板部を更に備え、一対の第１接触部のうちの一方と、一対の第２接触部のうちの一方とが弾性板部に設けられていることが好ましい。
　このような構成により、相手接続部と複数の接触部との接触信頼性を確保しつつ、相手接続部の挿入力を低減することができる。
　本発明の第１の特徴に係る接続端子によれば、部品点数を削減でき、回路抵抗を低減することができる接続端子を提供することができるという効果を奏する。
図１は、実施の形態に係る接続端子の断面図である。 図２は、実施の形態に係る接続端子の斜視図である。 図３は、実施の形態に係る接続端子において、相手接続部が挿入されていないときの断面図である。
　実施形態に係る接続端子１について、図１－３を用いて説明する。
　実施形態に係る接続端子１は、タブ状の相手接続部３が挿入される箱状の電気接続部５を備える。
　電気接続部５は、内部に連続する一部材で形成され、相手接続部３と接触される複数の接触部７を備える。
　複数の接触部７は、相手接続部３の挿入方向上流側に設けられ相手接続部３を狭持して接触する一対の第１接触部９ａ，９ｂと、相手接続部３の挿入方向下流側に設けられ相手接続部３を狭持して接触する一対の第２接触部１１ａ，１１ｂとを備える。
　さらに、複数の接触部７は、一対の第１接触部９ａ，９ｂと一対の第２接触部１１ａ，１１ｂとの間に設けられ、相手接続部３に接触する第３接触部１３を備える。
　接続端子１は相手接続部３の挿入により弾性変形可能な弾性板部１５を備える。一方の第１接触部９ｂと一方の第２接触部１１ｂとが弾性板部１５に設けられる。
　接続端子１は、導電性材料の１枚の板材からなり、板材に折り曲げ加工などを施すことによって形成された電線圧着部１７と電気接続部５とを備える。電線圧着部１７は、被覆圧着部１９と、芯線圧着部２１とを備える。
　被覆圧着部１９は、一対の圧着片からなり、機器などに接続された被覆電線（不図示）の端末部において、被覆電線の被覆部を圧着して被覆電線と接続端子１とが一体に固定される。芯線圧着部２１は、電気接続部５と被覆圧着部１９との間に設けられた一対の圧着片からなり、被覆電線の端末部において、被覆電線の被覆部から露出された芯線部を圧着して被覆電線と接続端子１とが電気的に接続される。
　電気接続部５は、底板が電線圧着部１７と連続する一部材で形成され、折り曲げ加工によって箱状に形成された雌型の接続部を備える。電気接続部５には、相手端子（不図示）のタブ状に形成された雄型の相手接続部３が挿入される。電気接続部５の内部には、相手接続部３と接触する複数の接触部７が設けられ、相手端子と接続端子１とが電気的に接続される。
　実施形態では、複数の接触部７は、一対の第１接触部９ａ，９ｂと、一対の第２接触部１１ａ，１１ｂと、第３接触部１３との５点の接触部を備える。一対の第１接触部９ａ，９ｂは、電気接続部５において、相手接続部３の挿入方向上流側に設けられている。上側に位置する第１接触部９ａは、上板２３と連続する一部材で形成され、電気接続部５の内部に向けて突接されている。
　弾性板部１５は、底板を電気接続部５の内部に向けて折り曲げ加工されることにより形成される。下側に位置する第１接触部９ｂは、弾性板部１５と連続する一部材で形成され、電気接続部５の内部に向けて突接されている。弾性板部１５は、電気接続部５に相手接続部３が挿入されることにより、底板側に向けて弾性変形可能に設けられている。
　第１接触部９ａ，９ｂは、電気接続部５に相手接続部３が挿入されると、相手接続部３の基部側の上下面に接触され、相手端子と接続端子１とを電気的に接続させる。
　第２接触部１１ａ，１１ｂは、電気接続部５において、相手接続部３の挿入方向下流側に設けられている。上側に位置する第２接触部１１ａは、上板２３と連続する一部材で形成され、電気接続部５の内部に向けて突接されている。
　下側に位置する第２接触部１１ｂは、弾性板部１５と連続する一部材で形成され、電気接続部５の内部に向けて突接されている。
　第２接触部１１ａ，１１ｂは、電気接続部５に相手接続部３が挿入されると、相手接続部３の先端側の上下面に接触され、相手端子と接続端子１とを電気的に接続させる。
　第３接触部１３は、電気接続部５において、第１接触部９ａと第２接触部１１ａとの間で、上板２３と連続する一部材で形成され、電気接続部５の内部に向けて突接されている。第３接触部１３は、電気接続部５に相手接続部３が挿入されると、相手接続部３の中央の上面に接触され、相手端子と接続端子１とを電気的に接続させる。
　複数の接触部７は、相手接続部３と接続端子１との材料の種類によって、電流が流れるメイン流路として第１接触部９と第２接触部１１とのうちいずれか一方を選択することができる。
　詳細には、例えば、相手接続部３と接続端子１とが銅合金で形成された同種の金属である場合には、相手接続部３と接続端子１との間の回路長が短くなる第１接触部９ａ，９ｂが大電流が流れるメイン流路となる。
　これに対して、例えば、相手接続部３が銅合金で形成され、接続端子１が銅合金よりも固有抵抗が高いステンレス鋼で形成された異種の金属である場合には、大電流が回路抵抗の低い相手接続部３を長く流れるので、第２接触部１１ａ，１１ｂがメイン流路となる。
　このように、実施形態では、メイン流路を選択可能とすることができるので、相手接続部３及び接続端子１の形状を変更することなく、相手接続部３と接続端子１との間を流れる電流の回路長を変更することができる。なお、メイン流路に選択されていない接触部は、低電流が流れるサブ流路となっている。
　接続端子１では、電気接続部５が内部に連続する一部材で形成され相手接続部３と接触される複数の接触部７を備える。そのため、複数の接触部７を電気接続部５と別体で形成させる必要がなく、部品点数を削減することができ、加えて、電気接続部５における回路抵抗を低減することができる。
　接続端子１では、複数の接触部７が電気接続部５で連続する一部材で形成されている。そのため、部品点数を削減でき、回路抵抗を低減することができる。
　複数の接触部７は、相手接続部３の挿入方向上流側に設けられた一対の第１接触部９ａ，９ｂと、相手接続部３の挿入方向下流側に設けられた一対の第２接触部１１ａ，１１ｂとを備える。そのため、相手接続部３と接続端子１との材料の種類によって電流が流れるメイン流路として第１接触部９ａ，９ｂと第２接触部１１ａ，１１ｂとのうちのいずれか一方を選択することができる。
　そのため、相手接続部３及び接続端子１の形状を変更することなく、相手接続部３と接続端子１との間を流れる電流の回路長を変更することができる。
　複数の接触部７は、一対の第１接触部９ａ，９ｂと一対の第２接触部１１ａ，１１ｂとの間に設けられ、相手接続部３に接触する第３接触部１３を備える。そのため、複数の接触部７は相手接続部３に対し５点の接触点を有することとなり、さらに回路抵抗を低減することができる。
　一方の第１接触部９ｂ及び一方の第２接触部１１ｂは、相手接続部３の挿入により弾性変形可能な弾性板部１５に設けられている。そのため、相手接続部３と複数の接触部７との接触信頼性を確保しつつ、相手接続部３の挿入力を低減することができる。
　実施形態に係る接続端子１では、接続端子１が被覆電線に圧着されて電気的に接続されている。しかし、これに限らず、例えば、接続端子１を回路基板の導体に電気的に接続するなど、接続端子１が接続される導通部材はどのようなものであってもよい。
　また、実施形態では、複数の接触部７は、相手接続部３に対して５点の接触点を有する。しかし、これに限らず、５点以上の接触点、または４点の接触点であってもよい。
　本発明によれば、部品点数を削減でき、回路抵抗を低減することができる接続端子を提供できる。
