Abstract
Description
そのため、このようなコネクタ11においては、コンタクト21がハウジングから抜けて徐々に緩んでくるおそれを払拭することができない。
図3は、本発明の一実施形態によるコンタクト31の斜視図であって、上下を反転させた状態で表している。このコンタクト31は、電鋳法によって作製される微小な接続端子である。図4(A)及び図4(B)は、コンタクト31の一部を拡大した図である。また、図5(A)は当該コンタクト31を組み込んだコネクタ51の断面図、図5(B)はフレキシブルプリント基板46を接続されたコネクタ51の断面図である。
図5(A)及び図5(B)に示すコネクタ51は、コンタクト31を組み込んだものである。このコネクタには、2種類のコンタクトがそれぞれ複数本組み込まれている。一方のコンタクトは、上記コンタクト31である。他方のコンタクトは、図1に示したコンタクト21において、図3のコンタクト31と同様に、その可動接点部25の接点接触面に凹凸形状41を設け、またその嵌合部27の圧接面に凹凸形状42を設けたものである。
つぎに、コンタクト31に凹凸形状41、42を設けることによる効果を説明する。このコンタクト31では、可動接点部35の接触面に凹凸形状41を形成しているので、可動接点部35の接触圧が凸条41aの先端に集中し、可動接点部35の接触圧が大きくなり、可動接点部35の接触信頼性が向上する。また、可動接点部35に凹凸形状41を設けていると、フレキシブルプリント基板46の電極パッド表面に生じている汚れや酸化膜が凸条41aによって破壊され、露出させた電極パッドの金属面に可動接点部35を接触させることができ、可動接点部35の接触信頼性が向上する。特に、図7(A)に示すように、凹凸形状41が可動接点部35の押圧方向P及びワイピング方向Wに垂直な方向に延びている場合には、凸条41aが電極パッド61に線状に当接して線状に当接している方向と直交する方向へワイピングされる。よって、線状に当接した凸条41aがそれと直交する方向へ移動して電極パッドの表面を面状にワイピングするので、電極パッドの表面の汚れや酸化膜を効率よく破壊することができ、可動接点部35の接触信頼性をより一層向上させることができる。
この効果を得るためには、図7(B)に示すように嵌合部37の全面に凹凸形状42を設ける必要はなく、図7(C)に示すように、嵌合部37の一部の面だけに凹凸形状42を設けていてもよい。
つぎに、好ましい凹凸形状について説明する。コンタクトは、一般に、金属板を打ち抜くことによって作製されることが多い。プレスにより金属板から打ち抜いたときの断面の顕微鏡写真を図8に示す。金属板をプレスで打ち抜いたときの断面には、筋状の剪断面と組織が潰れたような破断面とが表れていて、剪断面の筋が破断面で途切れている。ここで、金属板の厚みをD1、剪断面の長さ(厚み)をD2とすると、一般的には、D2/D1の値が1/2以上1/3以下である。このようなプレスによる断面をコンタクトの接触面として使用した場合には、相手部材に接触したときにコンタクトが片当たりして傾く。また、相手部材との接触も不安定になる。そのため、プレスによる断面はコンタクトの接触面としては好ましくない。
図9(A)のような円弧状の凹凸形状を有するモデルM1では、線接触のために接触圧が大きくなるので、ヘルツ(Hertz)理論(たとえば、NACHI-BUISINESS news, Vol.10D1, June 2006; 株式会社不二越 開発本部 開発企画部 2006年6月20日発行)を用いて接触圧を計算した。
円弧状の凸条が1本であれば、凸条(円筒)と平面の接触時の面圧は次の数式1で表される。
F:荷重(加圧力)
E:縦弾性係数
t:板厚
R:凸条の表面の曲率半径
である。
F:荷重
E:縦弾性係数
t:板厚
R:凸条の表面の曲率半径
f:凸条1本当たりにかかる力
n:凸条の本数
L:接触幅
s:凹凸の平均ピッチ
であって、f=F/n、L=n×s である。
F:荷重
t:板厚
L:接触幅
である。
F:荷重
t:板厚
L:接触幅
である。
凹凸の平均ピッチ s: 0.1mm
荷重(加圧力) F: 100gf
接触幅 L: 0.05mm
板厚 t: 0.1mm
曲率半径 R: 0.002mm
ヤング率とポアソン比については、コネクタ材料として最も多く用いられる「りん青銅」の値を使用した。
ヤング率E=1.2×105[N/mm2]
ポアソン比=0.3
この条件1は、大きな接触力を想定した条件である。この結果は次の表1の通りであった。
凹凸の平均ピッチ s: 0.004mm
荷重(加圧力) F: 10gf
接触幅 L: 10mm
板厚 t: 0.25mm
曲率半径 R: 0.025mm
ここでもヤング率とポアソン比については、コネクタ材料として最も多く用いられる「りん青銅」の上記値を使用した。
この結果は次の表2の通りであった。
以上述べたように、コンタクトの凹凸形状は25μm以下の幅の金属板に対して端から端まで連続的に形成された断面半円弧状の凸条を有するものが好ましい。このような凹凸形状を有するコンタクト、一般的にいえば金属板は、以下のようにして電鋳法で作製することができる。
図10(C)は図10(B)の平面図である。図11(A)は図11(B)に示すフォトマスクの下面図である。図12(A)は図12(B)の平面図である。図12(D)は金属部品の斜視図である。
電鋳法による金属部品の第2の製造方法を図16(A)-図16(C)、図17(A)、図17(B)及び図18(A)-図18(C)に示す。ここで、図16(A)、図17(A)、図17(B)及び図18(B)は断面図である。図16(B)は図16(A)の平面図である。図16(C)は図17(A)に示すフォトマスクの下面図である。図18(A)は図18(B)の平面図である。図18(C)は金属部品の斜視図である。
電鋳法による金属部品の第3の製造方法を図21(A)-図21(C)及び図22(A)-図22(D)に示す。ここで、図21(A)、図21(C)、図22(A)及び図22(C)は断面図である。図21(B)は図21(C)に示すフォトマスクの下面図である。図22(B)は図22(C)の平面図である。図22(D)は金属部品の斜視図である。
このマスクパターン105には、外周の一部又は全体に微細な凹凸115がデザインされている。なお、図21(B)では凹凸115は誇張して描いているが、マスクパターン105の大きさと比較しても凹凸115は微細なパターンである。図21(C)のようにフォトマスク104を通してレジスト膜102に露光すると、マスクパターン105の設けられていない領域ではフォトマスク104を光が透過してレジスト膜102が露光される。
つぎに、本発明に係る別な形態のコンタクトとコネクタを説明する。このコネクタ121は、たとえば携帯用電子機器に使用されるバッテリーの電極パッドに接触させて充電を行わせるためのコネクタである。図23は、当該コネクタ121を示す斜視図であって、図24は当該コネクタの断面図である。
また、コンタクト123は、コンタクトテール124aによってコネクタハウジング122に固定されている。
なお、コンタクト部126の接触部23a付近は他の部分に比べて幅狭となっている。
