Abstract
【解決手段】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系導電性物質を含有した熱可塑性樹脂からなることを特徴とする同軸ケーブル。
【選択図】 図1
Description
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。
