前記電線の外周を包囲するように配置された基板部と、
前記基板部の後縁から前記電線の軸線方向の後向きに片持ち状に延出した形態で、前記電線の周方向に複数並んで配置された延出部と、
各前記延出部の後端部を前記電線の径方向内向きに屈曲して形成され、前記電線の外面に食い込む複数の爪部と、
を有し、
前記周方向に隣合う前記爪部の相互間においては、前記径方向に沿って延び、且つ互いに対向する前記爪部の側縁同士が、前記軸線方向にずれている。
最初に本開示の実施形態を列記して説明する。
本開示の電線と外導体との圧着構造は、
(1)電線の端部に接続される外導体に設けられ、電線の外周に圧着されるオープンバレル状の圧着部を備えている。圧着部は、基板部と、複数の延出部と、複数の爪部と、を有している。基板部は、電線の外周を包囲するように配置される。複数の延出部は、基板部の後縁から電線の軸線方向の後向きに片持ち状に延出した形態で、電線の周方向に並んで配置される。複数の爪部は、各延出部の後端部を電線の径方向内向きに屈曲して形成され、電線の外面に食い込む。周方向に隣合う爪部の相互間においては、径方向に沿って延び、且つ互いに対向する爪部の側縁同士が、軸線方向にずれている。この構成によれば、周方向に隣合う爪部の相互間においては、周方向に対向する爪部の側縁が軸線方向にずれているので、爪部の突出端部を細らせなくても、隣合う爪部同士が干渉することを避けることができる。これによって、幅広の爪部の先端を電線の外面に食い込ませることができるので、外導体と電線とを強固に固着することができる。
[実施形態1]
本開示を具体化した実施形態1を、図1から図4を参照して説明する。図中、「前側」、「後側」は、それぞれ「F」、及び「B」で表される。
本開示を具体化した実施形態2を、図5から図7を参照して説明する。実施形態2の電線と外導体との圧着構造を有するシールド導電路200は、折り目F2が延びる向きが、実施形態1と異なる。その他の構成については実施形態1と同じであるため、同じ構成については、同一符号を付し、構造、作用及び効果の説明は省略する。図中、「前側」、「後側」は、それぞれ「F」、及び「B」で表される。
本開示は、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、請求の範囲によって示される。本発明には、請求の範囲と均等の意味及び請求の範囲内でのすべての変更が含まれ、下記のような実施形態も含まれることが意図される。
(1)実施形態1、2とは異なり、図8に示すように、軸線方向の寸法を3種類に異ならせた延出部228を設けてもよい。この場合、軸線方向の寸法が大きい延出部228の周方向の幅寸法を、軸線方向の寸法が小さい延出部228よりも大きくすることが好ましい。これによって、軸線方向の寸法が大きい延出部228を径方向に撓み難くすることができ、爪部230がシースに食い込んだ状態を保持し易くできる。
(2)爪部の先端における周方向の幅寸法を大きくする(すなわち、シースの外面に接触する爪部先端の接触寸法を大きくする)ことによって、外導体とシールド電線との固着をより強固にすることができる。このため、実施形態1、2とは異なり、図8に示すように、基板部226の後縁の全体にわたり延出部228を設けると、シースの外面に接触する爪部先端の接触寸法をより大きくすることができ、外導体とシールド電線との固着をより強固にすることができる。
(3)実施形態1、2とは異なり、シールド層を金属箔としてもよい。
