Description

【０００１】
【発明の属する技術分野】
本発明は、音響機器等の電子機器に使用して好適なコネクタ付き回転型電気部品に関する。
【０００２】
【従来の技術】
従来のコネクタ付き回転型電気部品を図１２に基づいて説明すると、回転型の可変抵抗器で構成される回転型電気部品Ｄ２は、可変抵抗器を形成する本体部Ｈ２と、この本体部Ｈ２から電気的に外部に導出するためのコネクタＫ２とで構成されている。
そして、可変抵抗器を形成する本体部Ｈ２は、箱形の絶縁材からなるケース３１に設けられたケース部３１ａと、このケース部３１ａ内に回転可能に取り付けられ、摺動子（図示せず）を設けた回転体３２と、ケース部３１ａの開放部に取り付けられ、摺動子が摺動する抵抗体（図示せず）を設けた絶縁基板（図示せず）とで構成されている。
【０００３】
また、外部に導出するための雌型のコネクタＫ２は、ケース部３１ａと一体に設けられて後方に突出する外壁部３１ｂと、抵抗体に電気的に導通した状態で絶縁基板に取り付けられて、外壁部３１ｂ内に配置された金属材からなる端子（図示せず）とで構成されている。
【０００４】
そして、このような回転型電気部品Ｄ２は、電子機器のシャーシ３３等に直立した状態で、適宜手段により取り付けられると共に、雄型のコネクタＫ３が雌型のコネクタＫ２に差し込まれて、本体部Ｈ２が電子機器内の電子回路に接続されている。
また、電子機器のパネル３４の孔３４ａには、外部から回転軸３５が挿通され、回転軸３５の端部に設けられたスナップ止め部３５ａが回転体３２の孔に挿入されて、回転体３５にスナップ結合された構成となっている。
【０００５】
そして、回転軸３５を回転すると、回転体３２が回転して回転型電気部品Ｄ２の操作が行われると共に、ケース部３１ａと回転体３２との間に形成されたストッパー手段により、回転軸３５，及び回転体３２の回転が停止するようになっている。
【０００６】
【発明が解決しようとする課題】
しかし、従来のコネクタ付き回転型電気部品Ｄ２は、シャーシ３３等に直立した状態で取り付けられるため、その取付強度が弱いという問題がある。
このため、回転体３２に結合された回転軸３５の操作時、回転軸３５がパネル３４の孔３４ａとの間の遊びの範囲でフラツキ、操作性が悪くなるという問題がある。
【０００７】
そして、この回転軸３５のフラツキを少なくするために、パネル３４の孔３４ａを小さくすると、この孔３４ａと回転体３２の孔とを一直線状に配置することが難しく、高精度のものが要求されるものである。
また、ケース部３１ａと回転体３２との間にストッパー手段が構成されるため、小型化の要求によって回転型電気部品Ｄ２が小型化されると、ストッパー手段もそれに伴い小さくなって、ストッパー強度が弱くなるという問題がある。
【０００８】
そこで、本発明は、取付強度が高く、回転軸の操作性の良好なコネクタ付き回転型電気部品を提供することを目的とする。
【０００９】
【課題を解決するための手段】

【００１０】
また、第２の解決手段として、前記軸受け部の外周部にネジ部が設けられた構成とした。

【００１１】
また、第４の解決手段として、前記回転軸と前記筺体とで、ストッパー手段を構成した。
また、第５の解決手段として、前記凹部の後方部には開放部が設けられ、この開放部を塞ぐように蓋体が前記筺体に取り付けられると共に、この蓋体によって、前記凹部内に収納された前記回転型電気部品の本体部の外側を覆うようにした構成とした。
【００１２】
また、第６の解決手段として、前記回転体を貫通した前記回転軸の前記一端側が前記蓋体の孔に挿入されて、前記蓋体によって支承された構成とした。
また、第７の解決手段として、前記回転軸は、外周部に位置する筒状部と、この筒状部の中央部に位置し、軸方向で後方に延びる軸部とを有し、前記筒状部が前記軸受け部に支承されると共に、前記軸部の一端側が前記回転体に挿通された状態で、前記蓋体によって支承された構成とした。

【００１５】
次に、本発明のコネクタ付き回転型電気部品の構成を図１〜図１１に基づいて説明すると、回転型の可変抵抗器で構成される回転型電気部品Ｄ１は、可変抵抗器を形成する本体部Ｈ１と、この本体部Ｈ１から電気的に外部に導出するためのコネクタＫ１とで構成されて、単体の部品として形成されている。
【００１６】
そして、可変抵抗器を形成する本体部Ｈ１は、絶縁材である合成樹脂の成型品からなる箱形のケース１に設けられたケース部１ａと、このケース部１ａの開放部に取り付けられ、抵抗体（図示せず）を設けた絶縁基板２と、このケース部１ａ内に収納された状態で回転可能に取り付けられた回転体３と、この回転体３に取り付けられ、抵抗体上を摺動する摺動子４とで構成されている。
【００１７】
また、外部に導出するための雌型のコネクタＫ１は、ケース部１ａと一体に形成されて、後方に突出する外壁部１ｂと、抵抗体に電気的に導通した状態で絶縁基板２に取り付けられて、外壁部１ｂ内に配置された金属材からなる端子５とで構成されている。
【００１８】
亜鉛ダイキャスト等の成型品からなる筺体６は、特に図５〜図８に示すように、板状の基部６ａを境にして前方部に軸受け部６ｂが設けられると共に、後方部に保持部６ｃが設けられている。
そして、軸受け部６ｂは、基部６ａを貫通した状態で、中心部に設けられた軸挿通用の孔６ｄと、外周部に設けられたネジ部６ｅを有すると共に、基部６ａには、前方に突出する突起からなる係合部６ｆが設けられている。
【００１９】
また、後方部に設けられた保持部６ｃは、切り欠き部６ｇを有するＵ字状の側壁６ｈと、外周がこの側壁６ｈによって囲まれて形成されて凹部６ｊとで形成されている。
そして、凹部６ｊは、その底面６ｋと反対側の後方部に開放部６ｍが設けられると共に、側壁６ｈには、切り欠き部６ｇの位置に凸部６ｎが設けられている。更に、筺体６の基部６ａには、底面６ｋから窪んだ窪み部６ｐが設けられると共に、この窪み部６ｐにストッパーを構成する係止部６ｑが設けられている。
【００２０】
合成樹脂等からなる回転軸７は、特に図９〜図１１に示すように、前方部に設けられた操作部７ａと、外周部に位置し、軸方向で後方に延びる筒状部７ｂと、この筒状部７ｂの中央部に位置し、軸方向で後方に延びる軸部７ｃとを有する。
また、筒状部７ｂの一端側には、鍔部７ｄと、この鍔部７ｄから径方向に突出し、ストッパーを構成する係止部７ｅが設けられると共に、筒状部７ｂの後端から後方側に突出する軸部７ｃの一端側には、非円形部７ｆと、この非円形部７ｆから更に後方に延びる円形の凸部７ｇが設けられている。
【００２１】
そして、この回転軸７は、図１，図２に示すように、筺体６の後方から孔６ｄに挿通され、鍔部７ｄを窪み部６ｐ内に収納、係止した状態で、筺体６の取り付ける。
この時、操作部７ａは軸受け部６ｂから前方に突出し、筒状部７ｂが軸受け部６ｂの孔６ｄに位置して、筒状部７ｂが軸受け部６ｂによって回転可能に支承されると共に、係止部７ｅと係止部６ｑとが係脱可能となって、ストッパー手段が形成される。
【００２２】
また、前記回転型電気部品Ｄ１は、回転体３の非円形の孔３ａに、回転軸７の一端側である凸部７ｇと非円形部７ｆを挿入した状態で、ケース１が保持部６ｃの凹部６ｊに収納され、側壁６ｈの内面に強嵌合した状態で保持される。
この時、非円形の孔３ａには、非円形部７ｆが強嵌合すると共に、凸部７ｇは、孔３ａから後方に突出した状態となる。
【００２３】
また、ケース１が保持部６ｃに収納された際、ケース１の前面が凹部６ｊの底面６ｋに載置された状態で、外形が略Ｄ型をなしたケース１が略Ｄ型をなした凹部６ｊに収納されて、ケース１の外側面が側壁６ｈに当接、支持されると共に、凸部６ｎがコネクタＫ１の外壁部１ｂに当接して、凸部６ｎと当接した反対側の外壁部１ｂがもう一方の側壁６ｈの切り欠き壁に押し付けられるようになっている。
そして、回転型電気部品Ｄ１のケース１が凹部６ｊに取り付けられた際、本体部Ｈ１のケース部１ａが凹部６ｊ内に位置すると共に、コネクタＫ１の外壁部１ｂが凹部６ｊから外方に突出している。
【００２４】
金属板等からなる蓋体８は、中央部から後方に突出し、孔８ａを設けた筒状の受け部８ｂを有し、この蓋体８は、凹部６ｊの後方部の開放部６ｍを塞ぐと共に、本体部Ｈ１の後方の外側を覆うように配置され、筺体６に設けられた取付片６ｒ（図３参照）を折り曲げることによって、筺体６に取り付けられている。
そして、蓋体８が取り付けられた際、本体部Ｈ１が蓋体８によって底面６ｋに押し付けられると共に、回転軸７の凸部７ｇが受け部８ｂの孔８ａに挿入され、凸部７ｇが受け部８ｂによって支承された状態となっている。
【００２５】
このように蓋体８を設けることによって、本体部Ｈ１の取付強度を一層高めることができると共に、蓋体８と軸受け部６ｂとで回転軸７を支承できて、回転軸７の回転操作を一層円滑にできる。
また、回転軸７が筒状部７ｂと軸部７ｃを有することにより、軸受け部６ｂによって支承される筒状部７ｂから軸部７ｃを分離でき、このため、筺体６への回転型電気部品Ｄ１の取付位置に若干の誤差があっても、軸部７ｃが容易に撓んで、回転体３の孔３ａへの軸部７ｃの係合が容易となる。
【００２６】
そして、上記のような構成を有するコネクタ付き回転型電気部品は、図２に示すように、電子機器のシャーシ９等に孔９ａ、９ｂを設け、孔９ａに軸受け部６ｂを挿通すると共に、孔９ｂに係合部６ｆを挿入、係合した状態で、軸受け部６ｂのネジ部６ｅにナット１０をねじ込みして、コネクタ付き回転型電気部品がシャーシ９等に取り付けられる。
このように、ナット１０で筺体６が取り付けられると、基部６ａの前面にシャーシ９等が圧接し、筺体６が強固に取り付けられると共に、回転型電気部品Ｄ１も筺体６に保持された状態で、強固に取り付けられた状態となる。
そして、この後、雄型のコネクタ１１が雌型のコネクタＫ１に差し込まれて、本体部Ｈ１が電子機器内の電子回路に接続されると共に、回転軸７の操作部７ａがパネル（図示せず）から突出した状態となる。
【００２７】
このように電子機器に組み込まれたコネクタ付き回転型電気部品の回転軸７の操作部７ａを回転すると、回転軸７は、軸受け部６ｂと受け部８ｂによって支承された状態で回転する。
そして、この回転により、非円形部７ｆに係合した回転体３が回転して、回転型電気部品Ｄ１の操作が行われると共に、筺体６と回転軸７とに設けられた係止部６ｑ、７ｅで形成されたストッパー手段により、回転軸７，及び回転体３の回転が停止するようになっている。
【００２８】
また、この回転軸７の回転時、回転軸７が筺体６によって支持されているため、回転軸７のブレ等は、筺体６によって抑えられ、回転型電気部品Ｄ１への影響が無くなる。
更に、回転軸７と筺体６との間でストッパー手段が形成されているため、ストッパー強度を大きくできると共に、軸部７ｃと分離した筒状部７ｂに設けた係止部７ｅによってストッパーを形成したため、ストッパー時において回転軸７に傾き等が生じても、軸部７ｃへの影響が少なく、回転体３が破壊されることがない。
【００２９】
なお、上記実施例では、回転型電気部品が可変抵抗器に適用したもので説明したが、回転型のエンコーダ等に適用しても良い。
【００３０】
【発明の効果】
本発明のコネクタ付き回転型電気部品において、回転軸７を回転可能に支承する軸受け部６ｂと、回転型電気部品Ｄ１を保持する保持部６ｃを設けた筺体６を有し、後方部に位置する保持部６ｃは、外周が側壁６ｈで囲まれた凹部６ｊで形成され、コネクタＫ１の外壁部１ｂが凹部６ｊから外方に突出した状態で、ケース１が凹部６ｊ内に収納、保持されたため、従来に比して、回転型電気部品Ｄ１が筺体６によって強固に取り付けできて、回転型電気部品Ｄ１の破損の無いものを提供できる。
また、回転軸７が軸受け部６ｂで支承された状態で回転するため、従来に比して、操作性の良好なものが提供できる。
【００３１】
また、軸受け部６ｂの外周部にネジ部６ｅが設けられたため、筺体６の取付が簡単であると共に、筺体６の強固な取付ができる。
【００３２】
また、側壁６ｈには、コネクタＫ１の外壁部１ｂを位置させる切り欠き部６ｇと、この切り欠き部６ｇに位置した凸部６ｎとが設けられ、この凸部６ｎによって、外壁部１ｂを押圧するようにしたため、外壁部１ｂの支持が強くなり、ケース１の取付が強固で、確実なものが得られる。
【００３３】
また、回転軸７と筺体６とで、ストッパー手段を構成したため、ストッパー強度を大きくでき、特に、回転型電位部品Ｄ１の小型化に伴って、有効なストッパーを提供できる。
【００３４】
また、凹部６ｊの後方部には開放部６ｍが設けられ、この開放部６ｍを塞ぐように蓋体８が筺体６に取り付けられると共に、この蓋体６によって、凹部６ｊ内に収納された回転型電気部品Ｄ１の本体部Ｈ１の外側を覆うようにしたため、この蓋体８で本体部Ｈ１を押し付けできて、回転型電気部品Ｄ１の筺体６への取付強度を一層高めることができる。
【００３５】
また、回転体３を貫通した回転軸７の一端側が蓋体８の孔８ａに挿入されて、蓋体８によって支承されたため、蓋体８と軸受け部６ｂとで回転軸７を支承できて、回転軸７の回転操作を一層円滑にできる。
【００３６】
また、回転軸７は、外周部に位置する筒状部７ｂと、この筒状部７ｂの中央部に位置し、軸方向で後方に延びる軸部７ｃとを有し、筒状部７ｂが軸受け部６ｂに支承されると共に、軸部７ｃの一端側が回転体３に挿通された状態で、蓋体８によって支承されたため、軸受け部６ｂによって支承される筒状部７ｂから軸部７ｃを分離でき、このため、筺体６への回転型電気部品Ｄ１の取付位置に若干の誤差があっても、軸部７ｃが容易に撓んで、回転体３の孔３ａへの軸部７ｃの係合の容易なものが得られる。
【００３７】
また、筒状部７ｂと筺体６とで、ストッパー手段を構成したため、ストッパー時において回転軸７に傾きが生じても、軸部７ｃへの影響が少なく、回転体３が破壊されることが無いものを提供できる。
