Abstract

L'invention concerne un dispositif de connexion de fils permettant de faciliter la fixation d'un ressort de serrage à une unique plaque à bornes, par fixation à l'aide d'une seule opération de ce ressort de serrage à l'unique plaque à bornes connectée à plusieurs fils, ce qui permet de diminuer le nombre de parties du dispositif, le nombre d'étapes de travail et le coût. Un unique ressort de serrage (7), des parties de fonctionnement (75), des parties de ressort (74), des parties de soutien (72a) et des parties de verrouillage (73) sont formées selon deux rangées en direction orthogonale par rapport à une direction d'insertion des fils. Les parties de verrouillage droite et gauche (73) sont connectées l'une à l'autre. Le ressort de serrage (7) prenant en sandwich deux fils est formé en tant que partie unique, il peut être fixé à l'unique plaque à bornes à l'aide d'une seule opération et ainsi le nombre de parties du dispositif ainsi que le nombre d'étapes de travail sont réduites. Même lorsqu'une partie de fonctionnement (75) est activée, il est possible de maintenir l'état fixe de l'autre partie de verrouillage (73) à l'autre extrémité de la plaque à bornes à l'aide d'une force élastique générée dans l'autre partie de ressort (74), et cela permet d'éviter un décalage de la position du ressort de serrage (7).
