Description
本発明の実施形態1を、図1ないし図7を参照しつつ説明する。本実施形態に係る端子付き電線10は、銅よりもイオン化傾向の大きな金属を含む芯線11を備えた電線12と、銅又は銅合金を含む端子13と、を備える。なお、以下の説明においては、図1における左方を前方とし、右方を後方として説明する。
電線12は、芯線11の外周を合成樹脂製の絶縁被覆14で包囲してなる。芯線11を構成する金属としては、銅よりもイオン化傾向の大きな金属を用いることが可能であって、例えば、マグネシウム、アルミニウム、マンガン、亜鉛、クロム、鉄、カドミウム、コバルト、ニッケル、スズ、鉛等、又はこれらの合金を例示することができる。本実施形態においては、芯線11はアルミニウム又はアルミニウム合金を含む。本実施形態に係る芯線11は複数の金属細線を撚り合わせてなる撚り線である。芯線11としては、金属棒材からなる、いわゆる単芯線を用いてもよい。アルミニウム又はアルミニウム合金は比較的に比重が小さいので、端子付き電線10を全体として軽量化することができる。
図1に示すように、端子13は、電線12の端部から露出された芯線11に圧着されて芯線11と電気的に接続されるワイヤーバレル部15と、ワイヤーバレル部15の後方に形成されて絶縁被覆14を保持するインシュレーションバレル部16と、ワイヤーバレル部15の前方に形成されて相手側端子17の雄タブ18が挿入される接続筒部19と、を備える。
図1に示すように、端子付き電線10のうち、端子13、芯線11、及び端子13のやや後方に位置する絶縁被覆14には、表面処理層24が形成されている。詳細には、絶縁被覆14の前端部寄りの部分、絶縁被覆14に圧着されたインシュレーションバレル部16、絶縁被覆14の前端部から露出された芯線11、芯線11に圧着されたワイヤーバレル部15、接続筒部19の外面及び内面、接続筒部19の内部に位置する弾性接触片22には、表面処理層24が形成されている。表面処理層24は、液体状又はペースト状をなす表面処理剤26を上記の領域に塗工してなる。表面処理層24は、図中、網掛けで示されている。
続いて、本実施形態に係る端子付き電線10の製造工程に一例を説明する。なお、端子付き電線10の製造工程は以下の記載に限定されない。
従来技術においては、図9に示すように、芯線1と端子3とに跨って水2が付着した場合に、芯線1、端子3、及び水2の間にいわゆる腐食電流が流れることにより、芯線1が電食により浸食されるおそれがある。
電食を抑制する仮想的な技術として、例えば、図6に示すように、芯線31と端子33とが接続された場合において、電食により浸食される芯線31の表面を絶縁性の被膜34で包囲する構成が考えられる。被膜34としては、合成樹脂、酸化被膜等が考えられる。
上記の点に鑑み、本実施形態に係る端子付き電線10は、銅又は銅合金を含む端子13の表面に、液体状又はペースト状をなすと共に端子13に親和性を有する親和性基と疎水性を有する疎水基とを分子構造中に有する表面処理剤26を含む表面処理層24が形成される構成とした。
次に、本発明の実施形態2を、図8を参照しつつ説明する。本実施形態に係る端子付き電線40は、銅よりもイオン化傾向の大きなアルミニウム又はアルミニウム合金を含む金属部材からなる芯線41を備えた複数(本実施形態では2本)の電線42と、複数の電線42の端部から露出された複数の芯線41に接続された銅又は銅合金を含む1つのスプライス端子43(端子13の一例)と、を備える。なお、実施形態1と重複する説明については省略する。
本発明は上記記述及び図面によって説明した実施形態に限定されるものではなく、例えば次のような実施形態も本発明の技術的範囲に含まれる。

12,42:電線
13:端子
