Une première rangée (21) de contacts (20) placés dans la première région de contact (5) se raccorde au conducteur électrique (2) et est produite avec un premier composant métallique (40). Une seconde rangée (31) de contacts (30) placés dans la seconde région de contact (6) raccorde le système de raccordement (3) du module solaire (100) et est produite avec un second composant métallique (50). La première et la seconde rangée (21, 31) de contacts (20, 30) sont placées dans un logement commun (80) qui entoure la première et la seconde ligne de contacts, au moins en partie, et qui est monté dans le logement de raccordement (10).
