La ou les broches à emmancher (300) possèdent le long de leur axe longitudinal (350) un premier segment d'emmanchement (310) ayant un premier diamètre extérieur (D2) et un deuxième segment d'emmanchement (320) ayant un deuxième diamètre extérieur (D2). Le circuit imprimé (200) est relié électriquement à l'autre circuit imprimé (220) par la ou les broches à emmancher (300) de telle façon que la broche (300) est emmanchée par son premier segment d'emmanchement (310) dans le premier orifice de connexion (210) du circuit imprimé (200) et connectée électriquement au circuit imprimé (200) et emmanchée par son deuxième segment d'emmanchement (320) dans le deuxième orifice de connexion (230) de l'autre circuit imprimé (220) et connectée électriquement à l'autre circuit imprimé (220). Selon l'invention, pour réaliser une connexion emmanchée la plus simple, la plus sûre et la plus économique possible, le premier diamètre intérieur (ID1) est plus grand que le deuxième diamètre intérieur (ID2) et le premier diamètre extérieur (D1) du premier segment d'emmanchement (310) est plus grand que le deuxième diamètre extérieur (D2) du deuxième segment d'emmanchement (320). L'invention concerne en outre un procédé de réalisation d'un système de connexion électrique (100) selon l'invention, ainsi qu'une broche à emmancher (300) destinée à un système de connexion électrique (100) selon l'invention.
