Abstract

L'invention décrit un système de connexion de signaux électriques, particulièrement des signaux haute fréquence, qui doivent être véhiculés par un câble d'alimentation possédant au moins un conducteur, vers un circuit électronique situé sur une carte de circuits imprimés. Le contact entre au moins un conducteur et la carte de circuits imprimés, normalement une de ses lignes, s'effectue par l'intermédiaire de moyens élastiques à résistance faible, qui présentent un contact approprié avec la carte de circuits imprimés et le conducteur lui-même, qui est guidé vers lesdits moyens élastiques. Si le câble d'alimentation possède un conducteur extérieur, le contact entre celui-ci et la carte de circuits imprimés, normalement sa configuration de base, s'effectue directement ou au moyen d'une vis en contact avec le conducteur extérieur et une pièce opposée, par exemple, une bague, qui peut présenter un contact approprié avec la carte de circuits imprimés. Il est possible, au moyen de cette invention, de connecter très facilement un câble d'alimentation possédant au moins un conducteur et il en résulte une économie de temps et d'argent lors de la première installation ou du remplacement de l'une des pièces concernées. L'invention se rapporte particulièrement à un connecteur de câble haute fréquence qui achemine des signaux reçus vers un convertisseur pour satellite de télédiffusion directe (DBS).
