Abstract

Filtre électromagnétique, dispositif électrique haute tension , véhicule et procédé associés Ce filtre électromagnétique (16) est adapté pour être disposé autour d’un connecteur haute tension (14) et comprend une pluralité d’éléments de filtrage (24), chaque élément de filtrage (24) délimitant un conduit d’accueil (30) adapté pour accueillir le connecteur haute tension (14), et une première et une deuxième enveloppe partielle (34, 36). Dans une configuration désinstallée, les première et deuxième enveloppes partielles sont disposées à l’écart de la pluralité d’éléments de filtrage (24), et dans une configuration installée, les première et deuxième enveloppes partielles sont disposées autour de la pluralité d’éléments de filtrage (24). Les enveloppes partielles enferment un volume d’accueil (37) des éléments de filtrage (24). Les enveloppes partielles (34, 36) comprennent chacun un orifice de passage (38, 39). Les orifices de passage sont disposés en regard l’un de l’autre et traversés par le connecteur haute tension (14) lorsque l’enveloppe (26) est en configuration installée. Figure pour l'abrégé : Figure 2Electromagnetic filter, high voltage electrical device, associated vehicle and method This electromagnetic filter (16) is adapted to be arranged around a high voltage connector (14) and comprises a plurality of filter elements (24), each filter element (24) defining a receiving conduit (30) adapted to receive the high voltage connector (14), and a first and a second partial envelope (34, 36). In an uninstalled configuration, the first and second partial envelopes are arranged away from the plurality of filter elements (24), and in an installed configuration, the first and second partial envelopes are arranged around the plurality of filter elements (24). The partial envelopes enclose a receiving volume (37) of the filter elements (24). The partial envelopes (34, 36) each comprise a passage orifice (38, 39). The through holes are arranged opposite each other and crossed by the high voltage connector (14) when the casing (26) is in the installed configuration. Figure for the abstract: Figure 2
