Abstract
Description
ところで、近年、自動車業界では環境への配慮から、車両を軽量化することによって燃費を向上させることが重要な課題となっている。このため、銅に比して軽量なアルミニウム、あるいはアルミニウム合金からなる導体部を用いた導体部と該導体部の外周を包囲する絶縁被覆部とを含む電線と、該電線の端末部に接続される電線接続部を含む端子金具と、を有してなる端子金具付き電線が注目されている。
しかしながら、アルミニウムは水および銅イオンの存在下では腐食し易いため、アルミニウム、あるいはアルミニウム合金からなる導体部と銅からなる端子金具との接続部分に水が侵入すると腐食し易いという問題があった。
そこで、導体部への水の付着を防ぐことによって導体部の腐蝕を防止するため、例えば特許文献1には、露出された導体部が配置される面に導体部の腐蝕を防止する防食剤が塗布されている端子金具付が記載さている。
図1は、本発明の実施例に係る端子金具付き電線1の分解斜視図である。図2は、図1に示した端子金具付き電線1の電線接続部40周辺の拡大斜視図である。図3は、図2に示した端子金具付き電線1のA-A線断面図である。図4は、図2に示した端子金具付き電線1のB-B線断面図である。
なお、本発明の実施例では説明の便宜上、図中矢印に示すように前後方向を定義する。
本発明の実施例に係る端子金具付き電線1は、導体部11と導体部11の外周を包囲する絶縁被覆部12とを含む電線10と、電線10の端末部10aに接続される電線接続部40を含む端子金具20と、を有してなる。
導体部11は、アルミニウム、あるいはアルミニウム合金からなる複数の素線11aが束ねられてなる。
絶縁被覆部12は、絶縁性の合成樹脂からなり、導体部11の外周を包囲するように形成されることによって、導体部11を外部から絶縁可能に保護するものである。
なお、導体部11は、複数の素線11aが束ねられてなるものを例示したが、これに限らず単芯線であっても構わない。
端子金具20は、銅、あるいは銅合金等の金属からなる板状部材が金型プレス加工等によって成形された端子金具である。この端子金具20は、不図示の接続相手端子との接続部分となる相手端子接続部30と、電線10の端末部10aに接続される電線接続部40と、相手端子接続部30と電線接続部40とを連結する中間部50とを有してなる。
この露出導体圧着部41は、露出された導体部11が載置される導体圧着底壁部41aと、導体圧着底壁部41aの両側縁から起立され、導体部11の両側部から上部にわたって導体部11の外周を包囲するように圧着される一対の導体圧着起立壁部41bとを有してなる。
また、露出導体圧着部41は、内側の面41cが凹凸形状に形成されてなる凹凸表面部44を有してなる。より具体的には、凹凸表面部44は、内側の面41cの複数箇所にひし形形状の凸部が連続して形成されてなる部分である。この凹凸表面部44は、露出導体圧着部41と導体部11との接触面積が増大されることによって密着強度を高める機能を有してなる。
なお、この実施例の端子金具付き電線1は、凹凸表面部44が内側の面41cの複数箇所にひし形形状の凸部が連続して形成されてなるものを例示したが、これに限らず、露出導体圧着部41の内側の面41cが凹凸形状に形成されるようになっていればその他の形状であっても構わない。
この絶縁被覆圧着部42は、絶縁被覆部12が載置される絶縁被覆圧着底壁部42aと、絶縁被覆圧着底壁部42aの両側縁から起立され、絶縁被覆部12の両側部から上部にわたって絶縁被覆部12の外周を包囲するように圧着される一対の絶縁被覆圧着起立壁部42bとを有してなる。
この中間一体連接部43は、絶縁被覆部12が載置される中間底壁部43aと、中間底壁部43aの両側縁から起立され、絶縁被覆部12の両側部から上部にわたって絶縁被覆部12の外周を包囲するように圧着される一対の中間起立壁部43bとを有してなる。
より具体的には、中間一体連接部43は、絶縁被覆部12に覆われた部分の電線10の外径と、露出された導体部11の部分の電線10の外径との差が小さくなるように、絶縁被覆圧着部42から露出導体圧着部41に向けて電線10の外径が漸次縮径されるように電線10に圧着されるようになっている。
このため、端子金具20を電線10に接続させた後に、端子金具20を絶縁樹脂Rが溶融される温度で加熱することによって、図3に示すように、露出導体圧着部41の絶縁樹脂の層60の未形成部分で露出導体圧着部41が導体部11に電気的に接続されつつ、電線接続部40の前端開口40bおよび後端開口40cが絶縁樹脂Rによって封止されるので、端子金具20の外部から、露出された導体部11に水が侵入されることを防ぐことができる。
まず、作業者は、不図示の加工機を用いて端子金具20の内側の面のうち、露出導体圧着部41の内側の面41cに未形成部分を残すようにして絶縁樹脂の層60を形成する(図5参照)。
この樹脂層形成工程では、複数の端子金具20が型抜き処理される前の板状部材21に対して、絶縁樹脂の層60が形成される。ここで、板状部材21に対して絶縁樹脂の層60を部分的に形成する場合、例えば、絶縁樹脂の層60の未形成部分に対応する部分にマスキングを施し、その後に絶縁樹脂Rを塗布するようにする。
このため、絶縁樹脂の層60が形成される部分、および絶縁樹脂の層60の未形成部分を板状部材21の図中横方向に連続する直線状に形成することができるようになっている。
このように、複数の端子金具20が型抜きされる前の板状部材21に絶縁樹脂の層60を形成することによって、複数の端子金具20に対して一括で絶縁樹脂の層60が形成されるようになっている。
なお、絶縁樹脂の層60は、板状部材21に対して型抜き加工を行なった後に形成するようにしても構わない。
次に、図8および図9を用いて本発明の実施例に係る端子金具付き電線1の変形例1について説明する。図8は、本発明の実施例の変形例1の端子金具付き電線2の電線接続部72周辺の拡大斜視図である。図9は、図8に示した端子金具70の材料となる板状部材71が型抜きされた状態を示した図である。
この変形例1の端子金具付き電線2は、端子金具70の絶縁被覆圧着部73に一対の圧着片部73a,73aが形成されてなる点で実施例の端子金具付き電線1と異なる。
なお、その他の構成は実施例と同様であり、実施例と同一構成部分には同一符号を付している。
次に、図10および図11を用いて本発明の実施例に係る端子金具付き電線1の変形例2について説明する。図10は、本発明の実施例の変形例2の端子金具付き電線3の電線接続部82周辺の拡大斜視図である。図11は、図10に示した端子金具の材料となる板状部材81が型抜きされた状態を示した図である。
この変形例2の端子金具付き電線3は、端子金具80の絶縁被覆圧着部83に貫通孔が形成されてなる点で実施例の端子金具付き電線1と異なる。

このような端子金具80は、絶縁被覆圧着部83が絶縁被覆部12に圧着された場合、絶縁被覆部12が貫通孔83a内にくい込まれるため、電線10の絶縁被覆部12により確実に圧着される。
なお、この変形例2の端子金具付き電線3は、絶縁被覆圧着部83の二箇所に貫通孔83aが形成されてなるものを例示したが、これに限らず、絶縁被覆圧着部83の少なくとも一箇所に貫通孔83aが形成されていればよい。
次に、図12を用いて本発明の実施例に係る端子金具付き電線1の変形例3について説明する。図12は、(a)が本発明の実施例の変形例3の端子金具付き電線4の端子金具90の材料となる板状部材91が型抜きされた状態を示した図であり、(b)が(a)のA-A線断面図である。
この変形例3の端子金具付き電線4は、端子金具90の電線接続部92の絶縁被覆圧着部93に凹凸表面部94が形成されてなる点で実施例の端子金具付き電線1と異なる。
なお、その他の構成は実施例と同様であり、実施例と同一構成部分には同一符号を付している。
この凹凸表面部94は、断面矩形状に内側の面93aから突出された凸部が並んで設けられてなる。このような端子金具90は、絶縁被覆圧着部93が絶縁被覆部12に圧着された場合、凹凸表面部94によって絶縁被覆圧着部93と絶縁被覆部12との接触面積が増大されることによって密着強度を高める機能を有してなる。
なお、この変形例3の端子金具付き電線4は、凹凸表面部94が断面矩形状に内側の面93aから突出された凸部が並んで設けられてなるものを例示したが、これに限らず、絶縁被覆圧着部93の内側の面93aが凹凸形状に形成されるようになっていればその他の形状であっても構わない。
次に、図13を用いて本発明の実施例に係る端子金具付き電線1の変形例4について説明する。図13は、(a)が本発明の実施例の変形例4の端子金具付き電線5の電線接続部110周辺の拡大斜視図であり、(b)が(a)のA-A線断面図である。
この変形例4の端子金具付き電線5は、端子金具100の電線接続部110が板状部分の両側端部110a,110bが重なり合う筒状に形成されてなる点で実施例の端子金具付き電線1と異なる。電線接続部110は、露出導体圧着部111と、絶縁被覆圧着部112と、中間一体連接部113と、を有してなる。
なお、その他の構成は実施例と同様であり、実施例と同一構成部分には同一符号を付している。
次に、図14を用いて本発明の実施例に係る端子金具付き電線1の変形例5について説明する。図14は、(a)が本発明の実施例の変形例5の端子金具付き電線6の電線接続部110周辺の拡大斜視図であり、(b)が(a)のA-A線断面図である。
この変形例5の端子金具付き電線6は、端子金具100の電線接続部110が板状部分の両側端部110a,110bが重なり合う筒状に形成されてなり、かつ露出導体圧着部111が重なり合う両側端部110a,110bのうち外側の側端部110bの内側の面に絶縁樹脂の層60が形成されてなる点で実施例の端子金具付き電線1と異なる。
なお、その他の構成は実施例と同様であり、実施例と同一構成部分には同一符号を付している。
