Abstract

Cette invention concerne un câble à contact intégré (1) comprenant un contact arrondi (5) qui présente un orifice traversant (5a) ménagé au centre de celui-ci et qui formé d'une seule pièce avec la pointe d'un fil central (3) par soudage par résistance effectué par circulation du courant entre des électrodes entre lesquelles est sertie une section de pointe du fil central (3), ladite section de pointe ayant été coudée en forme d'anneau. Au cours de la formation dudit contact arrondi (5), des bossages (5b) sont formés sur ses surfaces supérieure et inférieure, lesdits bossages (5a) étant concentriques avec ledit orifice traversant (5a). Pour le montage et la fixation du contact arrondi (5) à un objet (9), une section filetée mâle (11a) d'un axe (11) inséré à travers l'orifice traversant (5a) est vissée sur des filetages femelles ménagés dans un orifice de fixation (9a) dans ledit objet (9) de façon à fixer le contact arrondi (5) à l'objet (9). De cette manière, le bossage (5b) sur la surface inférieure de le contact arrondi (5) bute contre la surface de fixation (9b) de l'objet (9), de façon à empêcher la zone de contact entre le contact arrondi (5) et ladite surface de fixation (9b) de varier.
