Abstract

L'invention concerne un raccordement d'élément de blindage entre une carte de circuits, recevant des composants électriques et/ou électroniques, disposée dans un boîtier, et au moins une douille de raccordement, disposée dans une paroi du boîtier, comportant une gaine cylindrique métallique qui est introduite à travers la paroi de boîtier et qui présente, sur le côté extérieur de la paroi, une unité servant à recevoir une fiche mâle comportant un élément d'accouplement métallique correspondant, raccordé de manière électroconductrice à l'élément de blindage d'un câble prolongeant la fiche mâle. L'objectif de l'invention est de créer un raccordement d'élément de blindage, permettant que le raccordement électrique de la gaine de la douille de raccordement, raccordée électriquement au potentiel de l'élément de blindage du câble à raccorder, à la carte de circuits, par l'intermédiaire de laquelle le potentiel de blindage est distribué, s'effectue automatiquement lors de l'assemblage du boîtier. A cet effet, on fait appel, selon l'invention, à un élément de blindage métallique en forme de bague, qui présente des broches de contact faisant saillie à partir du plan de la bague, sur un côté de cette dernière, destinées à être raccordées mécaniquement et électriquement à la carte de circuits, ainsi que des branches élastiques, faisant saillie sur l'autre côté de bague, destinées à être mises en contact avec la gaine de la douille.
