Description
[発明の効果]
[発明を実施するための最良の形態]
図1は、本発明による同軸ケーブルの好ましい実施の形態の概略部分斜視図である。
このカーボン系導電性物質入り外被4は、導電性が付与された導電性外被となり、その結果、シールド効果の向上を図ることができる。
また、導電性外被4の被覆厚さは、ケーブル径が太くならないように、しかもシールド効果が減少しないように、できるだけ薄肉に形成することが好ましい。
この同軸ケーブル10のシールド効果の測定をネットワークアナライザ(アンリツ社製)を用いて行った結果を図2に示す。
10:同軸ケーブル。
Claims (1)
- 中心導体の周囲に誘電体層を設け、この誘電体層の周囲に外部導体層を設け、この外部導体層の周囲に外被を設けてなる同軸ケーブルにおいて、前記外被がカーボンナノチューブを含有した熱可塑性樹脂からなり、
前記外被は、70重量%〜99重量%の前記熱可塑性樹脂に、30重量%〜1重量%の前記カーボンナノチューブを配合したものであることを特徴とする同軸ケーブル。
