Abstract

L'invention concerne une borne de raccordement électrique dans laquelle la pression de contact d'une section de contact n'est ni augmentée ni réduite par la pression de contact d'un élément de restriction du déplacement sur un objet devant être raccordé; et un connecteur qui utilise ladite borne de raccordement. La borne de raccordement électrique est pourvue d'un élément de restriction du déplacement (24) qui restreint le déplacement dans le sens de retrait d'une borne d'appariement (3). Ainsi, après avoir été raccordée avec la borne d'appariement (3), même si la borne d'appariement (3) se décale dans le sens de retrait, une section de contact (21) peut être intégralement déplacée avec la borne d'appariement (3), sans que la section de contact (21) ne glisse contre la borne d'appariement (3). Dans ce cas, l'élément de restriction du déplacement (24) s'appuie contre la borne d'appariement (3) depuis le sens dans lequel une contre-force n'est pas générée dans le sens de contact de la section de contact (21) parmi les sens orthogonaux au sens d'insertion/retrait de la borne d'appariement (3). Ainsi, la pression de contact de l'élément de restriction du déplacement (24) n'est pas appliquée dans le sens de contact de la section de contact (21), et la pression de contact de la section de contact (21) augmente pas et ne se réduit pas non plus sous l'effet de la pression de contact de l'élément de restriction du déplacement (24).
