Description

アース用端子金具
　本発明は、アース用端子金具に関する。
　従来、電線の端末部に接続されるとともに所定のアース部位にボルト締めにより接続されるアース用端子金具が知られている。このアース用端子金具は、アース部位にボルト締めされるボルト締結部と、電線の端末部に接続される電線接続部とを有している。
　そして、アース用端子金具においては、接続された電線の端末部から電線内部に水が浸入することを防ぐべく、例えば下記特許文献１に記載のように、電線とアース用端子金具との接続部位を熱収縮チューブ等の止水部材で覆うことが知られている。この際、電線接続部をアース部位から浮かせて止水部材が入るスペースを確保するために、ボルト締結部と電線接続部とを繋ぐ繋ぎ部を屈曲した形状にすることが必要である。
特開２０００－２８５９８３公報
　しかしながら、ボルト締結部と電線接続部とを繋ぐ繋ぎ部は、他の部位に比して幅寸法が小さいため、振動等による力が集中して作用しやすく、そのような繋ぎ部を上記のような理由で屈曲した形状にすることは、応力集中を著しいものにしてしまう。そのような応力集中が長期にわたって継続することは、次第に強度を低下させ、ひいては破断を招く虞があるため対策が望まれていた。
　本発明は上記のような事情に基づいて完成されたものであって、繋ぎ部への応力集中を緩和することが可能なアース用端子金具を提供することを目的とする。
　本発明のアース用端子金具は、アース部位にボルト締めされるボルト締結部と、電線の端末部に接続される電線接続部とを有し、前記ボルト締結部と前記電線接続部の底板部とが面一に配され、前記ボルト締結部のうち前記ボルトが挿通されるボルト挿通孔の周囲には、前記アース部位側に突出する突部が設けられている。
　本発明によれば、ボルト挿通孔の周囲に設けられた突部がアース部位に当接することで電線接続部がアース部位から浮き、電線接続部の下側に止水部材用のスペースがあくから、ボルト締結部と電線接続部とを繋ぐ繋ぎ部を屈曲した形状にしなくてもよく、もって繋ぎ部への応力集中を緩和することができる。

　本発明の好ましい形態を以下に示す。
　本発明のアース用端子金具は、前記突部が、前記ボルト挿通孔の全周に連続して設けられた環状をなしているものとしてもよい。このような構成によれば、突部の強度が高いから、良好にアースをとることができる。
　＜実施例＞
　以下、本発明を具体化した一実施例について、図１～図６を参照しつつ詳細に説明する。
　本実施例におけるアース用端子金具１０は、電線３０の端末部に接続されるとともに例えば自動車のボディにおける所定のアース部位４０にボルト締めにより接続されてアースが取られるものである。以下、各構成部材において、図１の左手前側を前側、右奥側を後側、上側を上方、下側を下方として説明する。
　アース用端子金具１０は、金属板材をプレス加工することで形成され、アース部位４０にボルト締めされるボルト締結部１１と、電線３０の端末部に接続される電線接続部１２とを有し、ボルト締結部１１と電線接続部１２とが繋ぎ部１３によって一体に繋がった形態をなしている。
　ボルト締結部１１は、全体として略円形の平板状をなし、その中心部には、ボルト４１が挿通される略円形状のボルト挿通孔１４が貫通形成されている。ボルト締結部１１には、連れ回りを防止する手段として、回り止め部１５が一体に形成されている。回り止め部１５は、ボルト締結部１１の外周縁から径方向外向きに水平（ボルト締結部１１の板面に略平行）に延びた後、下側および前側に屈曲された形状をなしている。この回り止め部１５の先端が、図５に示すように、アース部位４０に設けられた溝部４２に挿入されて、ボルト締結部１１の回り止めがなされる。
　電線接続部１２は、電線３０の芯線３１に圧着される芯線圧着部１６と、絶縁被覆３２に圧着される被覆圧着部１７とを有している。芯線圧着部１６および被覆圧着部１７は、それぞれ底板部１８の両側縁から上方に突出する一対の芯線圧着片１６Ａおよび被覆圧着片１７Ａを備えている。電線接続部１２における底板部１８は、幅方向における略中心が最も下がり、両側縁が上がるように湾曲している。芯線圧着片１６Ａおよび被覆圧着片１７Ａは、底板部１８に載置された電線３０の芯線３１および絶縁被覆３２をそれぞれ包み込むようにしてかしめ付けられる。
　ボルト締結部１１と電線接続部１２の底板部１８とは、面一に配されている（図４参照）。繋ぎ部１３の幅方向における略中心は、前端から後端に至るまで略水平（ボルト締結部１１の板面に対して略平行）をなし、上下方向の段差はないものとされている。繋ぎ部１３の前端部はボルト締結部１１に段差なく連なり、繋ぎ部１３の後端部は芯線圧着部１６に段差なく連なっている。
　繋ぎ部１３の両側縁部には、上方に立ち上がるように屈曲されて形成された補強部１９が設けられている。補強部１９は、図３に示すように、前端から後端にかけて次第に上方への突出寸法が増しており、その上端面は後上がりの傾斜をなしている。補強部１９の後端は、芯線圧着部１６における底板部１８の湾曲部分に連なっている。なお、繋ぎ部１３の幅寸法は、図２に示すように、平面視において、前後方向に略一定とされている。
　そして、ボルト締結部１１の中心部には、下側（アース部位４０側）に突出する突部２１が設けられている。突部２１は、ボルト挿通孔１４の周囲に形成され、ボルト挿通孔１４の全周に連続して設けられた環状をなしている。突部２１は、ボルト挿通孔１４の周縁部を下側に凹ませることで形成され、突部２１の上側には凹部２２が形成されている。凹部２２は、図５に示すように、ワッシャ４３の外径寸法と同等の幅寸法、およびワッシャ４３の厚さ寸法と同等の凹み寸法を有し、ワッシャ４３の全体が収容される。
　突部２１は、図２に示すように、全周にわたり一定の幅寸法（径方向の寸法）を有し、平面視において円環状をなしている。突部２１の突出寸法は、図５に示すように、止水部材３３の厚さ寸法と同等もしくは若干大きい寸法とされている。突部２１の突出寸法は、全周にわたり略一定とされている。突部２１の突出面（下面）は、全体にわたり凹凸のない平坦な面とされ、その全体がアース部位４０に当接した状態になる。
　止水部材３３は、アース用端子金具１０を電線３０に圧着させた後に、アース用端子金具１０と電線３０との接続部位の全体を包囲するように施される。止水部材３３は、電線３０の絶縁被覆３２の端部から電線接続部１２（被覆圧着部１７および芯線圧着部１６）の全体、露出した芯線３１の全体、繋ぎ部１３の略全体にわたる部分を覆って、電線３０の端部を防水する。
　止水部材３３として、図５に示すように、内周面に接着剤（図示せず）が塗布された熱収縮チューブを被せてもよい。熱収縮チューブは、アース用端子金具１０と電線３０との接続部位に被せられた後に、所定の温度で加熱されて収縮し、アース用端子金具１０および電線３０に接着剤を介して密着する。
　また、止水部材３３として、図６に示すように、モールド樹脂によって包囲するものとしてもよい。モールド樹脂は、アース用端子金具１０と電線３０との接続部位をモールド成形用の金型（図示せず）にセットし、その金型内に溶融した樹脂を注入することにより成形される。モールド樹脂は、アース用端子金具１０と電線３０との接続部位の全体に隙間なく密着する。
　次に、上記のように構成された実施例の作用および効果について説明する。
　本実施例のアース用端子金具１０は、アース部位４０にボルト４１締めされるボルト締結部１１と、電線３０の端末部に接続される電線接続部１２とを有し、ボルト締結部１１と電線接続部１２の底板部１８とが面一に配され、ボルト締結部１１のうちボルト４１が挿通されるボルト挿通孔１４の周囲には、アース部位４０側に突出する突部２１が設けられている。
　この構成によれば、ボルト挿通孔１４の周囲に設けられた突部２１がアース部位４０に当接することで電線接続部１２がアース部位４０から浮き、電線接続部１２の下側に止水部材３３用のスペースがあくから、ボルト締結部１１と電線接続部１２とを繋ぐ繋ぎ部１３を屈曲した形状にしなくてもよく、もって繋ぎ部１３への応力集中を緩和することができる。
　また、突部２１が、ボルト挿通孔１４の全周に連続して設けられた環状をなしている。この構成によれば、突部２１の強度が高いから、良好にアースをとることができる。
　＜他の実施例＞
　本発明は上記記述及び図面によって説明した実施例に限定されるものではなく、例えば次のような実施例も本発明の技術的範囲に含まれる。
　（１）上記実施例では、突部２１が、ボルト挿通孔１４の全周に連続して設けられた環状をなしているが、これに限らず、突部は、例えばボルト挿通孔の周囲に、周方向に所定の間隔をあけて複数を設けるものとしてもよい。
　（２）上記実施例では、突部２１が、平面視円環状をなしているが、これに限らず、突部は、例えば平面視方形状をなすものとしてもよい。
