Description
スリーブは、編組とともにバレルで圧着される。特許文献1には、各突起によって絶縁部とスリーブとの間に空気層が形成され、バレルの圧着作業に起因するインピーダンスの低下を補うことができる旨記載されている。
これに対し、全長が同一径の円筒状をなす汎用のスリーブでは曲げ剛性を十分に確保することができないことがあり、バレルの圧着時にスリーブ自身が大きく潰れて、絶縁部を過度に圧縮させてしまうことがある。
本発明の第2によれば、凸部がバレル部で潰れて伸ばされるため、絶縁部が凸部で過度に圧縮されるのを良好に防止することができる。
(1)前記スリーブにおいて、前記凸部における径方向外側の端部には、前記バレル部で押圧され得る部位に、前記軸方向に沿った受け台部が設けられているとよい。これによれば、バレル部の押圧前に、受け台部の内面と絶縁部側との間に、軸方向に沿った隙間を形成することができ、絶縁部が過度に圧縮されるのをより確実に防止することができる。
本発明の実施例1を図1~図6によって説明する。本実施例1のスリーブ11は、シールド機能を有するシールド端子10に備わり、シールド電線60の端末部に接続される。
シールド電線60は、同軸ケーブルであって、図3および図4に示すように、高周波信号を伝達する導体からなる芯線部61と、芯線部61の周りを包囲するシールド部62とを備える。具体的には、シールド電線60は、芯線部61と、芯線部61の外周を覆う絶縁樹脂性の絶縁部63と、絶縁部63の外周を覆う編組からなるシールド部62と、シールド部62の外周を覆う絶縁樹脂性のシース64とを備えている。本実施例1の場合、絶縁部63とシールド部62との間に銅箔などの金属箔65の層が設けられている。銅箔などの金属箔65の層は、伝送路のインピーダンスを規定値に調整する役割をはたす。
シールド端子10は、図6に示すように、スリーブ11に加え、内導体端子12と、内導体端子12の周囲を取り囲む外導体端子13と、外導体端子13と内導体端子12との間に介在する誘電体14とを備えている。スリーブ11、内導体端子12および外導体端子13はいずれも金属製であり、誘電体14は合成樹脂製である。
スリーブ11は金属製であって、全体として円筒状をなし、図3および図4に示すように、金属箔65(絶縁部63側)とシールド部62との間に介挿される。スリーブ11は、少なくともバレル部(ワイヤバレル18およびインシュレーションバレル19)の前後長さを超える前後長さを有している。図6に示すように、スリーブ11は、前部に、ワイヤバレル18で押圧される前側被押圧領域33を有し、後部に、インシュレーションバレル19で押圧される後側被押圧領域34を有している。
スリーブ11は、シールド電線60におけるシールド部62と金属箔65(絶縁部63側)との間に前方から差し込まれる。図3に示すように、スリーブ11のうち、前側被押圧領域33を含む前部は、シース64よりも前方に配置され、後側被押圧領域34を含む後部は、シース64の内側に挿入された状態で配置される。図4に示すように、凸部36の受け台部37と金属箔65との間および端側凸部38の外周部39と金属箔65との間には、前後方向に一定間隔の隙間20が形成されている。
本発明は上記記述及び図面によって説明した実施例に限定されるものではなく、例えば次のような態様も本発明の技術的範囲に含まれる。
(1)凸部、端側凸部および凹部は、スリーブの曲げ加工後にスエージング加工などで形成されるものであってもよい。
(2)スリーブの合わせ縁は、溶接や接着材などの接合手段によって一体に接合されていてもよい。また、スリーブは、そもそも無端円筒状に加工されるものであってもよい。
(3)凸部は、スリーブの前後方向途中に複数設けられていてもよい。
(4)スリーブは、インシュレーションバレルで押圧され得る部位に、全周にわたって径方向外側に膨出する形状の凸部が設けられていてもよい。
(5)スリーブは、インシュレーションバレルで押圧されない構造であってもよい。また、バレル部からインシュレーションバレルを省略することも可能である。
(6)スリーブから端側凸部を省略することも可能である。
