Abstract

L'invention porte sur un appareil de connexion de deux cartes, comprenant un plateau et un siège de cartes qui s'assemblent par couplage, chacun des deux côtés du plateau dans le sens de l'épaisseur étant doté d'une rainure de réception. Le plateau comporte un module de signaux, et ce module de signaux possède des bornes de contact et des bornes de connexion, qui sont connectées électriquement et de manière à correspondre les unes aux autres. Les bornes de contact sont divisées en deux groupes s'étendant respectivement dans les deux rainures de réception. Toutes les bornes de connexion sont placées sur une partie de couplage du plateau. L'intérieur d'une rainure de couplage du siège de cartes est muni d'une pluralité de bornes de signaux qui sont destinées au contact et destinées à être connectées électriquement aux bornes de connexion. Deux cartes de données peuvent être agencées avec le plateau de façon à former un empilement, de sorte que la structure est compacte. Ces deux cartes de données peuvent être connectées au module de signaux sur le plateau, et, après que le plateau a été couplé au siège de cartes, elles sont simultanément connectées électriquement aux bornes de signaux au moyen du module de signaux, ce qui permet de réaliser la connexion des deux cartes de données par rapprochement à l'aide d'un siège de cartes et d'un plateau. Seule la partie de couplage s'assemble par couplage avec le siège de cartes, ce qui simplifie la structure dudit siège de cartes. La structure globale est compacte et relativement petite. L'invention concerne également un terminal mobile comprenant cet appareil de connexion de deux cartes.
