Abstract

La présente invention concerne un connecteur de transmission de signal haute fréquence à grande vitesse et fournit une technologie de connecteur pour ajuster l'impédance caractéristique d'une broche la plus à l'extérieur parmi une pluralité de broches agencées par un élément de réglage d'impédance s'étendant à partir d'un élément de blindage pour un blindage contre des ondes électromagnétiques afin de transmettre de manière stable des signaux haute fréquence à grande vitesse. En particulier, la présente invention résout le problème selon lequel il est difficile de sécuriser l'espace pour un élément de blindage entre des broches du connecteur dans un état dans lequel le pas entre les broches est davantage réduit et la taille du connecteur est également réduite davantage. De plus, la présente invention est destinée à résoudre le problème de l'augmentation de la taille globale du connecteur en raison de l'augmentation du nombre de broches de réseau afin d'utiliser la broche la plus à l'extérieur finale en tant que broche de masse.
