  • the flat contact reduces tolerances and forces due to the torsion and bending of the spring arms within the contact chamber.

Abstract

L'invention concerne un ensemble connecteur plat comportant un contact plat qui présente une partie de contact à lame, un connecteur homologue qui présente une paire de lames de contact destinée à recevoir la partie de contact à lame, et des bras élastiques pour amortir les mouvements relatifs entre la partie de contact à lame et la paire de lames de contact, les bras élastiques étant formés d'un seul tenant sur les côtés étroits longs du contact plat, et des parties d'extrémité formées des bras élastiques étant montées coulissantes, comme crochets d'encliquetage, dans une chambre de contact. L'invention concerne en outre un contact plat réalisé avantageusement pour cet ensemble connecteur plat.
