Description
しかしながら、係止面積を大きく確保しても、端子金具とランスの係止部分では、金属からなる端子金具の係止穴に樹脂製のランスが係止するため、係止穴の穴縁係止端面におけるエッジが鋭いと、エッジがランスに食い込み、ランスの剪断破壊の開始強度が大幅に低下する問題があった。
(1)コネクタハウジングに形成される端子収容室に設けられた弾性変形可能なランスに係止されて前記端子収容室に装着される端子金具において、
前記ランスが係止する係止穴の穴縁係止端面に、前記ランスへの食い込み抵抗を増大させる食い込み抵抗増大部が形成され、かつ前記食い込み抵抗増大部が少なくとも前記穴縁係止端面の上縁に複数の凹凸が形成された波形状部であることを特徴とする端子金具。
また、食い込み抵抗増大部が、穴縁係止端面を部分的に潰したことにより形成される波形状部となり、食い込み抵抗や、剪断抵抗を増大させる食い込み抵抗増大部が容易に形成可能となる。
図1(a)は穴縁係止端面11の上部に波形状部13が形成された本発明に係る端子金具15の要部断面図、(b)は穴縁係止端面11の上部及び下部に波形状部13が形成された変形例に係る端子金具15の要部断面図、図2(a)はコネクタハウジング17における端子受入口19の正面図、(b)はそのA−A断面図である。
本実施の形態に係る端子金具15は、雄端子金具21(図3参照)、又は雌端子金具23(図3参照)のいずれであってもよい。但し、いずれの端子金具15であってもランス25が係止する係止穴27を有することが構成要件となる。
図3(a)に示す雄端子金具21は、先端に電気接触部47である雄タブ49を有し、その後方に端子本体部51と、導体圧着部53と、外被保持部55と、が順次連設されてなる。雄端子金具21は、金属板を板金加工することによって作られる。
なお、図1(a)(b)において、穴縁係止端面11の下部に形成された半円状の膨出部は接触バネ部59の雄タブ49との接圧を上げるように作用するインデントである。
端子金具15は、端子収容室31の所定位置に挿入されると、弾性復帰したランス25が、端子金具15の係止穴27に係止する。係止穴27に係止したランス25は、係止部43が係止穴27の穴縁係止端面11に当接する。係止された端子金具15に引き抜き方向の外力が作用すると、穴縁係止端面11がランス25の係止部43を押圧する。
図6は比較例に係る端子金具15の要部断面図、図7(a)は穴縁係止端面11にR付け部65が形成された他の実施の形態に係る端子金具15の要部断面図、(b)はそのD−D断面図である。
この実施の形態に係る端子金具15Aは、ランス25に食い込む際の抵抗力を上げるため、尖った端面(すなわち、角部63)をなくすことで、抵抗力をあげている。すなわち、この例による食い込み抵抗増大部61は、穴縁係止端面11の係止側の角部63を除去して形成したR付け部65としている。
