前記端子接触用ばね部材は、前記接触用平板部の挿入側となる前記端子嵌合部の前端部に内接する略四角形の第1枠部と、前記端子嵌合部の後端部に内接する略四角形の第2枠部と、前記端子嵌合部に挿入された前記接触用平板部の一方の表面と対向する前記第1枠部及び前記第2枠部の第1対向壁間に架設されて前記接触用平板部の一方の表面に弾性接触する第1板ばね部と、前記端子嵌合部に挿入された前記接触用平板部の他方の表面と対向する前記第1枠部及び前記第2枠部の第2対向壁間に架設されて前記接触用平板部の他方の表面に弾性接触する第2板ばね部と、を有し、
前記第1枠部と前記第2枠部は、装着前における側壁部の前記接触用平板部の板厚方向に沿う高さ寸法が、前記端子嵌合部の対応する内方の高さ寸法よりも大きく設定されるとともに、前記側壁部には、当該側壁部の高さ寸法を高さ方向に伸縮可能にする湾曲形状部が設けられている雌端子金具。
電線接続部12は、電線を圧着接続する部位である。
さらに、第2枠部22の第1対向壁22aから延出する側壁片22fにおける接触用平板部210の挿入方向の手前側に位置する側縁S4と、第2枠部22の第2対向壁22bから延出する側壁片22gにおける接触用平板部210の挿入方向の奥側に位置する側縁S3と、が当接して、側壁片22fが図3の矢印X2方向に移動することが規制される。
また、本出願は、2013年10月7日出願の日本特許出願(特願2013-210434)に基づくものであり、その内容はここに参照として取り込まれる。
前記端子接触用ばね部材(20)は、前記接触用平板部(210)の挿入側となる前記端子嵌合部(11)の前端部(11a)に内接する略四角形の第1枠部(21)と、前記端子嵌合部(11)の後端部(11b)に内接する略四角形の第2枠部(22)と、前記端子嵌合部(11)に挿入された前記接触用平板部(210)の一方の表面(211)と対向する前記第1枠部(21)及び前記第2枠部(22)の第1対向壁(21a,22a)間に架設されて前記接触用平板部(210)の一方の表面(211)に弾性接触する第1板ばね部(23)と、前記端子嵌合部(11)に挿入された前記接触用平板部(210)の他方の表面(212)と対向する前記第1枠部(21)及び前記第2枠部(22)の第2対向壁(21b,22b)間に架設されて前記接触用平板部(210)の他方の表面(212)に弾性接触する第2板ばね部(24)と、を有し
前記第1枠部(21)と前記第2枠部(22)は、装着前における側壁部(21c,22c)の前記接触用平板部(210)の板厚方向に沿う高さ寸法(H3)が、前記端子嵌合部(11)の対応する内方の高さ寸法(H4)よりも大きく設定されるとともに、前記側壁部(21c,22c)には、当該側壁部(21c,22c)の高さ寸法(H3)を高さ方向に伸縮可能にする湾曲形状部(R)が設けられている雌端子金具(1)。
