Description

基板用コネクタ
　本発明は、基板用コネクタに関するものである。
　特許文献１には、回路基板に取り付けられるハウジングと、ハウジングに取り付けた複数の端子金具とを備えた基板用コネクタが開示されている。ハウジングは、端子保持部の外周から前方へフード部を突出させた形態である。端子金具は、回路基板の実装面と平行に端子保持部を貫通した端子接続部と、端子保持部の後方で回路基板の実装面に固着される基板接続部と、端子保持部の後端と基板接続部の前端とを繋ぐ連結部とを備えている。
特開２０１０－０２０９８４号公報
　上記基板用コネクタでは、回路基板からの端子接続部の高さが異なる２種類の端子金具が用意されている。端子接続部の高さが異なる２種類の端子金具は、その全長の長さも異なるため、製造コストが高くつくという問題がある。
　本発明は上記のような事情に基づいて完成されたものであって、コスト低減を図ることを目的とする。
　本発明は、
　端子保持部の外周から前方へフード部を突出させた形態であり、回路基板の実装面に取り付けられるハウジングと、
　前記端子保持部の後方において前記実装面に固着される前後方向の基板接続部と、前記端子保持部を前後方向に貫通する端子接続部とを有し、前記実装面からの前記端子接続部の高さが異なる複数種類の細長い端子金具とを備え、
　前記複数種類の端子金具のうち少なくともいずれか１つの前記端子金具は、前記実装面からの前記端子接続部の高さ寸法より長く、前記基板接続部の前端と前記端子接続部の後端とを繋ぐ余長繋ぎ部を備えているところに特徴を有する。
　余長繋ぎ部を有する端子金具は、余長繋ぎ部の形状に応じて、実装面からの端子接続部の高さを任意に設定することができるので、端子接続部の高さの異なる複数種類の端子金具の全長を、共通の寸法に揃えることができる。したがって、全長の異なる複数種類の端子金具を用意する場合に比べると、コストを低減できる。

　本発明は、前記端子接続部の後端が、前記基板接続部の前端より後方に配されていてもよい。この構成によれば、余長繋ぎ部の長さを十分に長く確保することができる。

　ハウジング１０は、実装面Ｓとほぼ直角をなす壁状の端子保持部１１と、端子保持部１１の外周縁から前方へ角筒状に突出した形態のフード部１２とを有する。ハウジング１０は、全体として上下方向に比べて左右寸法の小さい横長の扁平な形状をなしている。
　＜第１端子金具１３＞
　第１端子金具１３は、１本の細長い金属線材に曲げ加工を施すことにより、所定形状に成形されている。第１端子金具１３は、前後方向に細長い第１基板接続部１４（請求項に記載の基板接続部）と、前後方向に細長い第１端子接続部１５（請求項に記載の端子接続部）と、側面視形状が屈曲した細長い形状の第１余長繋ぎ部１６（請求項に記載の余長繋ぎ部）とを有する単一部品である。
　全ての第１端子金具１３は、ハウジング１０の幅方向（左右方向）の中央部を除いた領域に配されている。全ての第１基板接続部１４は、幅方向に所定の間隔を空けて実装面Ｓに固着されている。全ての第１基板接続部１４の前端1４Ｆは前後方向において同じ位置に揃うように配され、全ての第１基板接続部１４の後端１４Ｒは前後方向において同じ位置に揃うように配されている。全ての第１端子接続部１５は、実装面Ｓより高い位置において同じ高さに揃うように配されている。全ての第１端子接続部１５の前端１５Ｆは前後方向において同じ位置に揃うように配され、全ての第１端子接続部１５の後端１５Ｒは前後方向において同じ位置に揃うように配されている。

　図２に示すように、第１余長繋ぎ部１６は、実装面Ｓからの第１端子接続部１５の高さ寸法よりも全長が長く、側面視形状は概ねＳ字形をなしている。即ち、第１余長繋ぎ部１６は、第１基板接続部１４の前端１４Ｆから上後方へ折り返すように立ち上がる弧状の下部曲線部１７と、下部曲線部１７の上端（後端）から斜め上後方へ延出する直線部１８と、直線部１８の上端（後端）から上前方へ折り返すように延出する弧状の上部曲線部１９とによって構成されている。下部曲線部１７の下端（後端）と第１基板接続部１４の前端１４Ｆは滑らかに連なっている。上部曲線部１９の上端（前端）と第１端子接続部１５の後端１５Ｒは滑らかに連なっている。
　＜第２端子金具２０＞

　全ての第２端子金具２０は、ハウジング１０の幅方向（左右方向）の中央部を除いた領域に配されている。全ての第２基板接続部２１は、幅方向に所定の間隔を空けて実装面Ｓに固着されている。第１基板接続部１４と第２基板接続部２１は、幅方向において交互に並ぶように配されている。全ての第２基板接続部２１の後端２１Ｒは、前後方向において互いに同じ位置に揃うように配され、且つ前後方向において第１基板接続部１４の後端１４Ｒと同じ位置に揃うように配されている。全ての第２基板接続部２１の前端２１Ｆは、前後方向において互いに同じ位置に揃うように配され、且つ前後方向において第１基板接続部１４の前端１４Ｆより後方の位置に配されている。
　図１，３に示すように、全ての第２端子接続部２２は、第１端子接続部１５より高い位置（実装面Ｓより高い位置）において同じ高さに揃うように配されている。全ての第２端子接続部２２の前端２２Ｆは、前後方向において互いに同じ位置に揃うように配され、且つ前後方向において第１端子接続部１５の前端１５Ｆと同じ位置に揃うように配されている（図２を参照）。図４に示すように、全ての第２端子接続部２２の後端２２Ｒは、前後方向において互いに同じ位置に揃うように配され、且つ前後方向において第１端子接続部１５の後端１５Ｒより僅かに前方の位置に配されている。
　図３に示すように、各第２端子金具２０においては、第２基板接続部２１と第２端子接続部２２が、幅方向において同じ位置に揃うように配されている。同じく各第２端子金具２０においては、第２基板接続部２１の前端２１Ｆが第２端子接続部２２の後端２２Ｒよりも僅かに後方に配されている。第２基板接続部２１の前端２１Ｆと第２端子接続部２２の後端２２Ｒは、第２余長繋ぎ部２３を介して繋がっている。
　図２に示すように、第２余長繋ぎ部２３の側面視形状は概ね直線状であるが、第２余長繋ぎ部２３の全長は、第２基板接続部２１（実装面Ｓ）からの第２端子接続部２２の高さ寸法よりも長い。即ち、第２余長繋ぎ部２３は、側面視において、第２端子接続部２２及び第２端子接続部２２と直角な方向に対して少し前傾するように傾いている。また、第２余長繋ぎ部２３の下端部は、曲率半径の小さい下部曲げ部２４を介して第２基板接続部２１の前端２１Ｆと滑らかに連なっている。第２余長繋ぎ部２３の上端部は、曲率半径の小さい上部曲げ部２５を介して第２端子接続部２２の後端２２Ｒと滑らかに連なっている。
　＜第３端子金具２６＞
　第３端子金具２６は、１本の細長い金属線材に曲げ加工を施すことにより、所定形状に成形されている。第３端子金具２６の全長は、第１端子金具１３及び第２端子金具２０よりも短い寸法である。第３端子金具２６は、前後方向に細長い第３基板接続部２７（請求項に記載の基板接続部）と、前後方向に細長い第３端子接続部２８（請求項に記載の端子接続部）と、側面視形状及び背面視形状がほぼ直線状をなす第３余長繋ぎ部２９（請求項に記載の余長繋ぎ部）とを有する単一部品である。
　図１，３に示すように、一対の第３端子金具２６は、ハウジング１０の幅方向（左右方向）の中央部に配されている。一対の第３基板接続部２７は、幅方向に所定の間隔を空けて実装面Ｓに固着されている。一対の第３基板接続部２７の前端２７Ｆは、前後方向において互いに同じ位置に揃うように配され、且つ前後方向において第２基板接続部２１の前端２１Ｆと同じ位置に揃うように配されている。一対の第３基板接続部２７の後端２７Ｒは、前後方向において互いに同じ位置に揃うように配され、且つ前後方向において第１基板接続部１４の後端１４Ｒ及び第２基板接続部２１の後端２１Ｒと同じ位置に揃うように配されている。
　一対の第３端子接続部２８の前端２８Ｆは、前後方向において互いに同じ位置に揃うように配され、且つ前後方向において第１端子接続部１５の前端１５Ｆ及び第２端子接続部２２の前端２２Ｆと同じ位置に揃うように配されている（図２を参照）。一対の第３端子接続部２８の後端２８Ｒは、前後方向において互いに同じ位置に揃うように配され、且つ前後方向において第１端子接続部１５の後端１５Ｒより僅かに前方で第２端子接続部２２の後端２２Ｒより僅かに後方の位置に配されている。
　各第３端子金具２６においては、第３基板接続部２７と第３端子接続部２８が、幅方向において互いに異なる位置に配されている。そして、一対の第３端子金具２６は左右対称な形状である。即ち、図３に示すように、一対の第３基板接続部２７の幅方向の間隔は、一対の第３端子接続部２８の幅方向の間隔よりも広い。また、各第３端子金具２６においては、第３基板接続部２７の前端２７Ｆが第３端子接続部２８の後端２８Ｒよりも僅かに後方に配されている。第３基板接続部２７の前端２７Ｆと第３端子接続部２８の後端２８Ｒは、第３余長繋ぎ部２９を介して繋がっている。
　第３余長繋ぎ部２９の側面視形状は概ね直線状であるが、第３余長繋ぎ部２９の全長は、実装面Ｓからの第３端子接続部２８の高さ寸法よりも長い。即ち、第３余長繋ぎ部２９は、側面視において、第３端子接続部２８及び第３端子接続部２８と直角な方向に対して少し前傾するように傾いている。この前傾角度は、第２余長繋ぎ部２３と同じ角度である。また、第３余長繋ぎ部２９は、側面視においても、第３端子接続部２８及び第３端子接続部２８と直角な方向に対して左右に傾いている。第３余長繋ぎ部２９の下端部は、曲率半径の小さい下部屈曲部（図示省略）を介して第３基板接続部２７の前端２７Ｆと滑らかに連なっている。第３余長繋ぎ部２９の上端部は、曲率半径の小さい上部屈曲部（図示省略）を介して第３端子接続部２８の後端２８Ｒと滑らかに連なっている。
　＜実施例の効果＞
　本実施例１の基板用コネクタＡは、ハウジング１０と、複数の第１端子金具１３と、複数の第２端子金具２０と、一対の第３端子金具２６とを備えている。ハウジング１０は、端子保持部１１の外周から前方へフード部１２を突出させた形態であり、回路基板Ｐの実装面Ｓに取り付けられる。
　第１端子金具１３は、端子保持部１１の後方において実装面Ｓに固着される前後方向の第１基板接続部１４と、端子保持部１１を前後方向に貫通する第１端子接続部１５とを有する。実装面Ｓからの第１端子接続部１５の高さは、第２端子金具２０の第２端子接続部２２及び第３端子金具２６の第３端子接続部２８よりも低い。第２端子金具２０は、端子保持部１１の後方において実装面Ｓに固着される前後方向の第２基板接続部２１と、端子保持部１１を前後方向に貫通する第２端子接続部２２とを有する。実装面Ｓからの第２端子接続部２２の高さは、第１端子接続部１５及び第３端子接続部２８よりも高い。
　第３端子金具２６は、端子保持部１１の後方において実装面Ｓに固着される前後方向の第３基板接続部２７と、端子保持部１１を前後方向に貫通する第３端子接続部２８とを有する。実装面Ｓからの第３端子接続部２８の高さは、第１端子接続部１５より高く、第２端子接続部２２より低い。このように、第１端子金具１３、第２端子金具２０及び第３端子金具２６は、実装面Ｓからの第１接続端子金具、第２端子接続部２２及び第３端子接続部２８の高さが互いに異なっている。
　そして、第１端子金具１３は、実装面Ｓからの第１端子接続部１５の高さ寸法より長く、第１基板接続部１４の前端１４Ｆと第１端子接続部１５の後端１５Ｒとを繋ぐ第１余長繋ぎ部１６を備えている。第２端子金具２０は、実装面Ｓからの第２端子接続部２２の高さ寸法より長く、第２基板接続部２１の前端２１Ｆと第２端子接続部２２の後端２２Ｒとを繋ぐ第２余長繋ぎ部２３を備えている。第３端子金具２６は、実装面Ｓからの第３端子接続部２８の高さ寸法より長く、第３基板接続部２７の前端２７Ｆと第３端子接続部２８の後端２８Ｒとを繋ぐ第３余長繋ぎ部２９を備えている。
　第１端子金具１３の第１余長繋ぎ部１６は略Ｓ字形に屈曲しており、実装面Ｓからの第１端子接続部１５の高さは、第１余長繋ぎ部１６の形状に応じた設定となっている。第１端子接続部１５の後端１５Ｒは第１基板接続部１４の前端１４Ｆより後方に配されているので、第１余長繋ぎ部１６の長さが十分に長く確保されている。また、第２端子金具２０の第２余長繋ぎ部２３は実装面Ｓと直角な方向に対して傾斜しているとともに、第２余長繋ぎ部２３の上下両端部が弧状の曲げ部２４，２５となっているので、実装面Ｓからの第２端子接続部２２の高さは、第２余長繋ぎ部２３の形状に応じた設定となっている。
　このように、第１端子金具１３と第２端子金具２０には、夫々、第１余長繋ぎ部１６と第２余長繋ぎ部２３が設けられており、これにより、実装面Ｓからの第１端子接続部１５と第２端子接続部２２の高さを互いに異なる任意の高さに設定することが実現できた。そして、この第１端子接続部１５と第２端子接続部２２の高さの異なる２種類の端子金具（第１端子金具１３と第２端子金具２０）の全長を、共通の寸法に揃えることができた。したがって、本実施例１の基板用コネクタＡは、全長の異なる複数種類の端子金具を用意する場合に比べると、コストを低減できる。
　＜実施例２＞
　次に、本発明を具体化した実施例２を図５を参照して説明する。本実施例２の端子金具３０は、端子接続部３２の後端３２Ｒが基板接続部３１の前端３１Ｆよりも後方に位置している。基板接続部３１の前端３１Ｆと端子接続部３２の後端３２Ｒは余長繋ぎ部３３を介して繋がっている。余長繋ぎ部３３は、基板接続部３１（実装面Ｓ）からの端子接続部３２の高さ寸法よりも全長が長く、側面視形状は概ねＳ字形をなしている。余長繋ぎ部３３は、基板接続部３１の前端３１Ｆから上方へ略直角に延出した第１直線部３４と、第１直線部３４の上端から後方へ略直角に延出した第２直線部３５と、第２直線部３５の後端から上方へ略直角に延出した第３直線部３６とを備える。第３直線部３６の上端は端子接続部３２の後端３２Ｒと略直角に連なっている。
　＜実施例３＞
　次に、本発明を具体化した実施例３を図６を参照して説明する。本実施例３の端子金具４０は、端子接続部４２の後端４２Ｒが基板接続部４１の前端４１Ｆよりも後方に位置している。基板接続部４１の前端４１Ｆと端子接続部４２の後端４２Ｒは余長繋ぎ部４３を介して繋がっている。余長繋ぎ部４３は、基板接続部４１（実装面Ｓ）からの端子接続部４２の高さ寸法よりも全長が長く、側面視形状は直線状をなしている。即ち、余長繋ぎ部４３は、基板接続部４１及び端子接続部４２の長さ方向と直角な上下方向に対して後傾するように傾斜している。余長繋ぎ部４３の下端は基板接続部４１の前端４１Ｆと鋭角状に連なり、余長繋ぎ部４３の上端は端子接続部４２の後端４２Ｒと鋭角状に連なっている。
　＜実施例４＞
　次に、本発明を具体化した実施例４を図７を参照して説明する。本実施例４の端子金具５０は、端子接続部５２の後端５２Ｒが基板接続部５１の前端５１Ｆよりも前方に位置している。基板接続部５１の前端５１Ｆと端子接続部５２の後端５２Ｒは余長繋ぎ部５３を介して繋がっている。余長繋ぎ部５３は、基板接続部４１（実装面Ｓ）からの端子接続部５２の高さ寸法よりも全長が長く、側面視形状は全体として直線状をなしている。余長繋ぎ部５３は、基板接続部４１及び端子接続部５２の長さ方向と直角な上下方向に対して前傾するように傾斜している。余長繋ぎ部５３の下端部は、基板接続部４１の前端４１Ｆに対し下部曲線部５４を介して滑らかに連なり、余長繋ぎ部５３の上端部は、端子接続部５２の後端５２Ｒに対し上部曲線部５５を介して滑らかに連なっている。
　＜実施例５＞
　次に、本発明を具体化した実施例５を図８を参照して説明する。本実施例５の端子金具６０は、端子接続部６２の後端６２Ｒが基板接続部６１の前端６１Ｆよりも前方に位置している。基板接続部６１の前端６１Ｆと端子接続部６２の後端６２Ｒは余長繋ぎ部６３を介して繋がっている。余長繋ぎ部６３は、基板接続部６１（実装面Ｓ）からの端子接続部６２の高さ寸法よりも全長が長く、側面視形状は全体として直線状をなしている。余長繋ぎ部６３は、基板接続部６１及び端子接続部６２の長さ方向と直角な上下方向に対して僅かに前傾するように傾斜している。
　余長繋ぎ部６３の下端部は、基板接続部６１の前端６１Ｆに対し下部曲線部６４を介して滑らかに連なり、余長繋ぎ部６３の上端部は、端子接続部６２の後端６２Ｒに対し上部曲線部６５を介して滑らかに連なっている。実施例５の余長繋ぎ部６３は、前方への傾き方が実施例４の余長繋ぎ部５３の傾きより小さく、直角に近い角度である。また、実施例５の余長繋ぎ部６３の下部曲線部６４と上部曲線部６５の曲率半径は、実施例４の余長繋ぎ部５３の下部曲線部５４と上部曲線部５５の曲率半径より大きい。
