Abstract

L'invention concerne un connecteur rapide de câbles électriques isolés par perforation de l'isolant qui comprend au moins deux éléments (1, 2) diélectriques, susceptibles d'être serrés et fermés l'un contre l'autre. Une partie d'un câble électrique isolé est saisie entre les deux éléments dont l'un contient une pièce (3) de matériau électroconducteur présentant au moins une protubérance pénétrante, formée d'un élément mince se terminant en pointe aiguisée qui peut perforer la couche de l'isolant (A) du câble sans l'endommager à peine et atteindre l'âme (B) d'un câble de manière à établir un contact électrique. Cette pièce (3) comprend une partie allongée, insérée dans un desdits éléments (1, 2) et s'étendant vers l'extérieur à partir d'au moins une de ses extrémités dans le prolongement de la protubérance pénétrante (3a). On prévoit des moyens de connexion de l'autre extrémité de la partie allongée de la pièce (3) à une câble électrique par soudure ou par perforation au moyen d'une pointe aiguisée.
