Abstract

L'invention concerne un dispositif (50; 60) comportant des barres de connexion fixes (51; 61) pour la connexion conductrice de premières barres conductrices (30; 130; 230) avec de deuxièmes barres conductrices (133; 233; 334) dont les côtés de contact (70; 170; 270, 173; 273; 374) sont parallèles, les barres conductrices pouvant être maintenues les unes contre les autres sous pression au moyen d'un premier et d'un deuxième dispositif de connexion (80, 80) présentant respectivement un boulon de connexion (81) perpendiculaire aux côtés de contact. Chaque barre de connexion (51; 61) comporte une première surface de contact (56; 66) pour la mise en contact conductrice du côté de contact (70; 170; 270) d'une des premières barres conductrices (30; 130; 230), et une deuxième surface de contact (57; 67) pour la mise en contact conductrice du côté de contact (173; 273; 374) d'une des deuxièmes barres conductrices (133; 233; 334). Pour simplifier davantage la connexion des premières et deuxièmes barres conductrices, notamment lorsque celles-ci sont prémontées en segments, par exemple dans des segments de modules de puissance d'une éolienne, les barres de connexion (51; 61) présentent un premier évidement (53; 63) et un deuxième évidement (54; 64) ouverts unilatéralement, respectivement sur le côté orienté vers les boulons de connexion (81), pour recouvrir les boulons de connexion (81).
