Abstract

　La présente invention concerne une section de connexion de fil d'une borne de sertissage (10) pourvue d'une section de sertissage (30) à sertir sur un conducteur (52) d'un câble. La section de sertissage (30) comporte une plaque inférieure (33) qui permet de placer le conducteur (52) sur la surface supérieure, et deux éléments de sertissage (31, 32) qui s'étendent vers le haut à partir des deux bords latéraux de la plaque inférieure (33) dans la direction de la largeur. Les deux éléments de sertissage (32, 33) sont courbés vers l'intérieur de façon à s'enrouler autour du conducteur (52), qui a été placé sur la plaque inférieure (33), par sertissage, sertissant et connectant ainsi le conducteur (52). De plus, lorsque les deux éléments de sertissage (31, 32) ont été sertis sur le conducteur (52) et connectés à ce dernier, cela donne une forme de sertissage avec laquelle les deux éléments de sertissage (31, 32) ne s'enfoncent pas dans le conducteur (52).
