Abstract

Une partie d'emboutissage (20) de couvercle présentant une section transversale en U est disposée au niveau de la partie d'extrémité arrière d'une borne (1), et, dans un état dans lequel une partie couvercle (WB) d'isolation à partir d'une extrémité d'un fil (W) recouvert est disposée sur la face supérieure d'une partie plaque (21) inférieure, des segments (22) d'emboutissage de couvercle sont emboutis de sorte à s'enrouler autour de la partie couvercle (WB) d'isolation. Une face (23) plate est formée sur la face supérieure de chaque segment (22) d'emboutissage de couvercle en vue de rendre la partie couvercle (WB) d'isolation sensiblement rectangulaire en section transversale suite à un sertissage par rétreint. Deux extrémités (T2) dans le sens de la largeur gauche et droit de la face (23) plate s'étendent vers l'extérieur dans le sens de la largeur au-delà des positions des extrémités (T1) gauche et droite de la partie couvercle (WB) d'isolation suite à un sertissage par rétreint.
