Abstract

L'invention vise à produire une force normale renforcée d'une lamelle de contact, par rapport à une lame de contact insérée, pour établir une connexion par fiches entre une partie de douille et une partie de connecteur. A cet effet, il est prévu, selon l'invention, qu'une autre force normale N4 s'exerce, en plus de la force normale N3 exercée par la lamelle de contact (3), approximativement dans la même direction. Cette force normale N4 est induite par une lamelle de ressort (4) supplémentaire selon l'invention, qui est disposée de préférence sur la face de la lamelle de contact (3) opposée à la lame de contact (2). Dans l'exemple de mode de réalisation représenté, la force normale N4 s'exerce sur le même point de contact (5) de la lamelle de contact (4).
