Abstract
Description
本発明の実施の形態に係る高周波電線は、図1に示すように、アルミニウム(Al)又はアルミニウム合金からなる中心導体1と、中心導体1を被覆する銅(Cu)からなる被覆層2と、中心導体1と被覆層2と間に、中心導体1から被覆層2にかけて傾斜的に組成が変化するように形成され、被覆層2よりも体積抵抗率が大きい金属間化合物層(合金層)3とを備える。
次に、本発明の実施の形態に係る高周波電線の製造方法を説明する。なお、以下に示す製造方法は一例であり特に限定されるものではない。本発明の実施の形態に係る高周波電線は種々の製造方法により製造することが可能である。
本発明の実施例1として、減面率がそれぞれ20%以上の複数の伸線ダイスを用いて、図1に示すように中心導体1と被覆層2の間に金属間化合物層3が形成され、被覆層2の断面積が高周波電線全体の断面積の5%である高周波電線(以下、「5%CCA線」という。)を作製した。まず、直径9.5mmのアルミニウムからなる中心導体1の上に0.15mm厚の銅テープを縦添え方式で添わせながらTIG溶接し、スキンパスで直径9.25mmに成形し、母材を作製した。この母材を、複数段(26パス)の伸線ダイスを通し、直径9.25mmから直径0.4mmに引き落とした。伸線ダイスのリダクション角度αは一律8°(全角2α=16°)とし、第1パス〜第3パスの減面率を29%〜24%、第4パス〜第10パスの減面率を23%〜21%、第11パス〜第26パスの減面率を21%〜20%とした。
本発明の実施例2として、図17(a)〜図17(c)に示すように、0.4mmに線引きした5%CCA線にポリウレタンを被覆した巻線(以下、「5%CCA巻線」という。)を作製し、磁心32と、磁心32の周りに配置された5%CCA巻線31を備えるリアクトルを作製した。5%CCA巻線31は14本用い、その巻数を80ターンとした。また、比較例としてアルミニウム巻線及び銅巻線を用いてリアクトルをそれぞれ作製した。作製した各リアクトルを用いて直流抵抗及び交流抵抗を測定した。
本発明の実施例3として、本発明の第2の実施例と同様の5%CCA巻線を用いたリアクトルの他に、図1に示した被覆層2の断面積が電線全体の断面積の15%である高周波電線の巻線(以下、「15%CCA巻線」という。)、被覆層2の断面積が電線全体の断面積の10%である高周波電線の巻線(以下、「10%CCA巻線」という。)、中心導体1としてアルミニウム合金(JIS6063合金)を使用し、被覆層2の断面積が電線全体の断面積の5%である高周波電線の巻線(以下、「合金アルミ5%CCA巻線」という。)を用いたリアクトルを、5%CCA巻線を用いたリアクトルと同じ条件でそれぞれ作製した。
本発明は上記の実施の形態によって記載したが、この開示の一部をなす論述及び図面はこの発明を限定するものであると理解すべきではない。この開示から当業者には様々な代替実施の形態、実施例及び運用技術が明らかとなろう。
