Abstract

L’invention concerne un harnais plat destiné à transmettre des signaux électriques, comportant un blindage tressé (3) délimité par des faces quasi aplaties (31, 33) comportant deux faces plates (31) de largeur prédéterminée et deux tranches (33) d’épaisseur prédéterminée, chacune desdites faces (31, 33) comportant un motif de tressage (35, 37) différent de ceux des deux faces adjacentes, le motif de tressage (35) sur chaque face plate (31) étant défini par un premier angle de tressage et un premier coefficient de remplissage, le motif de tressage (37) sur chaque tranche (33) étant défini par un deuxième angle de tressage et un deuxième coefficient de remplissage, et en ce que les premier et deuxième angles de tressage ainsi que les premier et deuxième coefficients de remplissage sont configurés pour que les impédances de transfert partielles relatives aux faces plates (31) du blindage tressé (3) soient au moins partiellement en opposition de phase par rapport aux impédances de transfert partielles relatives aux tranches (33) du blindage tressé (3). Figure pour l'abrégé: Fig. 1AThe invention relates to a flat harness intended for transmitting electrical signals, comprising a braided shield (3) delimited by quasi-flattened faces (31, 33) comprising two flat faces (31) of predetermined width and two slices (33) of predetermined thickness, each of said faces (31, 33) comprising a braiding pattern (35, 37) different from those of the two adjacent faces, the braiding pattern (35) on each flat face (31) being defined by a first angle of braiding and a first fill coefficient, the braiding pattern (37) on each slice (33) being defined by a second braiding angle and a second filling coefficient, and in that the first and second braiding angles as well as the first and second fill coefficients are configured so that the partial transfer impedances relative to the flat faces (31) of the braided shield (3) are at least partially in phase opposition with respect to the transfer impedances t partial relating to the edges (33) of the braided shield (3). Figure for the abstract: Fig. 1A
