ケーブル10の接続端側には、ケーブル10内の芯線と電気的に接続される金属製のオスコンタクト26が接続され、ケーブル12の接続端側には、ケーブル12内の芯線と電気的に接続される金属製のメスコンタクト28が接続される。オスコンタクト26の外周面には、複数の切り起こし片26aが形成されており、同様に、メスコンタクト28の外周面にも、複数の切り起こし片28aが形成されている。
次に、ケーブル10のオスコンタクト26とケーブル12のメスコンタクト28とを電気的に接続し、その接続を機械的にロックするためのロック機構について説明する。
図9A~Cは本発明の第2実施形態によるコネクタの図である。本実施形態において、第1実施形態と同一または同様の部分は、同一の符合を付し、その詳細説明を省略する。
ケーブル10のオスコンタクト26とケーブル12のメスコンタクト28とを電気的に接続し、その接続を機械的にロックするためのロック機構について説明する。
