Abstract

L'invention porte sur une boîte de jonction électrique dans laquelle des connecteurs connectés électriquement aux extrémités de fils sont fixés à un cadre, et à l'aide de laquelle la longueur en surplus des fils peut être rendue minimale. Cette boîte de jonction électrique (1) comprend : un cadre (2) auquel des connecteurs (7) connectés électriquement aux extrémités de fils (W1) sont fixés; et un dispositif de support de connecteur (5) qui contient les connecteurs (7) et des connecteurs de compagnon (8) auxquels les connecteurs (7) sont accouplés. Les fils (W1) sont routés depuis l'autre surface latérale (2d) du cadre (2) vers la surface latérale (2c) (le côté de connecteur (7)). Les connecteurs (7) sont introduits dans le dispositif de support de connecteur (5) sensiblement dans la même direction que la direction de routage des fils (W1). Les connecteurs de compagnon (8) sont appariés aux connecteurs (7) par introduction des connecteurs de compagnon dans le dispositif de support de connecteur (5) dans la direction opposée à la direction de routage. Le dispositif de support de connecteur (5) est fixé au cadre (2) dans une direction intersectant la direction de routage.
