Abstract

L'invention porte sur un système de connecteur prévu pour connecter une paire de cartes de circuit imprimées espacées parallèles. Un système de borne coaxiale est utilisé pour interconnecter des signaux entre les cartes. Le système de borne coaxiale peut comprendre un conducteur externe estampé et mis en forme. Le conducteur externe peut présenter une section droite rectangulaire. Un filtre passe-bande peut être incorporé dans un ou plusieurs des ensembles borne coaxiale, par exemple par insertion d'un élément adaptateur quart d'onde dans chaque ensemble borne. L'élément adaptateur est disposé à l'intérieur d'un isolateur et crée un chemin électrique entre le contact central et le blindage externe. Des éléments d'antenne peuvent être montés sur une carte de circuit imprimé ou, la carte de circuit imprimé étant éliminée, être montés directement sur les bornes.
