Abstract
Description
上記接続部は、オス型端子のオスタブ、メス型端子のボックス部等とすることができる。
前記トランジション被覆部は、トランジション被覆部だけ、あるいは、その他の部位を被覆する被覆部とで一体化された樹脂被覆部で構成することができる。
上記構成により、導体部分とトランジションの内側表面との接触部分にトランジション被覆部を構成しているため、効果的に電食を防止することができる。
上記バレル長は、前記接続部と前記インシュレーションバレル部とを結ぶ長手方向におけるワイヤーバレル部の長さとすることができる。
この構成により、導体部分と圧着端子との導電性能を確保しながら、電食防止効果を向上することができる。詳しくは、樹脂被覆部の被覆厚が5μm未満では、樹脂被覆部の絶縁層としての被覆が不完全となり、水分を透過するおそれがあり、金属基材の貴な金属のカソードとしての働きを十分に防止することができない。逆に、樹脂被覆部の被覆厚が30μmを超えると、圧着部のワイヤーバレル内部において、樹脂被覆部が形成されていない金属露出部と導体部分との電気的な導通を阻害して接触抵抗が増大する。これに対し、樹脂被覆部の被覆厚を5μm以上30μm以下とすることにより、端子表面を十分に絶縁してカソードとしての働きを防止して導体部分の電食を防止するとともに、十分な導電性能を確保することができる。
金属基材の切断や打ち抜き等による形状加工により、加工端面では金属が露出し、導体部分と接触することにより金属基材の金属部分はカソードとして機能し、導体部分に電食が生じるが、加工端面から露出した金属を樹脂で被覆する端面被覆部により、加工端面がカソードとして機能して導体部分が電食することを防止することができる。
この構成により、前記トランジションにおける前記導体部分の露出部分が外界と環境遮断され、より確実に導体部分の電食を防止することができる。
なお、前記金属基材の全表面積に対する前記樹脂被覆部で被覆する被覆面積の比率である被覆面積率を10%以上とし、被覆面積率の上限は端子サイズやアルミ導体サイズによって変化するが、50%~90%とするのが望ましい。
この構成により、導電性能を確保しながらの電食防止効果を得ることができる圧着端子を確実に作製することができる。
また、樹脂被覆部20は、ポリアミドイミドをストライプ状に塗布して構成している。
上述したように、圧着端子1は、図3(a)に示すように、銅合金条を圧着端子1の形状に応じて打ち抜いてリールを作製し、折り曲げ加工及びリールからの分離加工を施して作製する。なお、樹脂被覆部20(21,22)は、リールを作製する前の銅合金条において形成される。
まず、銅合金条に樹脂被覆部20を形成し、続いて、電気めっき浴を用いて錫めっきを電気めっきし、700℃にて5秒間リフロー処理し、光沢のあるリフロー錫めっき101を金属基板100に形成する。例えば、図3(a),(c)に示すように、端子形状にプレス打ち抜き、曲げ加工し、2.3II型メス端子(0.64II型メス端子)である圧着端子1を成形し、成形した圧着端子1に対して、打ち抜き加工性および曲げ加工性の評価を行った。なお、どちらの評価とも、各水準から抜き取った3個の圧着端子1に対して行った。
初期抵抗測定、および腐食試験は、各水準ともサンプル数20個について実施し、その全てについて、抵抗上昇値と腐食状況とを測定、観察した。
さらにまた、錫めっきはリフロー錫めっきに限定されず、錫の電気めっきの後リフロー処理をしない、いわゆる無光沢錫めっきであっても良い。
これにより、接続構造体1bにおける導電性能を確保しながらの電食防止効果を向上することができる。
第5効果確認試験は、上記第2効果確認試験における、No.301、No.312、No.401、No.412の圧着端子1に芯線202を圧着した接続構造体1bにおいて、芯線202が露出する露出部202aに、樹脂被覆部20の形成に使用した樹脂と同じ樹脂(アクリレート系樹脂、スリーボンド製3052C)を、露出部202aが無くなるように塗布し、紫外線を照射して硬化させて構成した(No.501、512、601、612)。なお、被覆電線200の逆端側は、第1効果確認試験と同様の処置とした。
第5効果確認試験の結果について表5に示す。
まず、所定寸法の錫めっき銅合金条をプレス打抜き加工して、図14(a)に示すように、接続構造体1aの形状となるとした端子リール120を作製する。通常、端子リールは曲げ加工を施して端子リールとすることが多いが、本実施例では曲げ加工をしていない状態で端子リール120とする。
