La pluralité de bornes sont positionnées dans la pluralité de fentes de borne, et chacune des bornes est formée d'un seul tenant avec une portion de fixation et une portion de transition dans un mode de déchargement d'une tôle métallique. La portion de fixation se présente sous la forme d'un corps de plaque, et la portion de fixation est fixée à la fente de borne. La portion de transition est pourvue d'une plaque courbée, d'une portion élastique supérieure qui se courbe et s'étend vers le haut, et d'une portion élastique inférieure qui se courbe et s'étend vers le bas. La plaque courbée est reliée à un côté de la portion de fixation et elle est pliée à 90 degrés ou 180 degrés, de sorte qu'une surface de plaque de la portion de transition est perpendiculaire ou parallèle à une face de plaque de la portion de fixation. Une extrémité de la portion élastique supérieure est reliée à la plaque courbée et l'autre extrémité de celle-ci est reliée à une portion de contact supérieure, et la portion de contact supérieure s'étend à travers une extrémité supérieure de la fente de borne. Une extrémité de la portion élastique inférieure est reliée à la plaque courbée et l'autre extrémité de celle-ci est reliée à une portion de contact inférieure, et la portion de contact inférieure s'étend à travers une extrémité inférieure de la fente de borne.
