Abstract

L'invention concerne un adaptateur pour connecteur de carte mémoire comprenant un support de réception d'une carte mémoire standard de taille supérieure. L'adaptateur comprend une partie de logement diélectrique avant et une partie de logement diélectrique arrière montée sur la partie de logement avant. Les deux parties de logement combinées ont une forme sensiblement identique à celle de la carte de taille supérieure. Une enveloppe métallique est montée sur la partie de logement arrière et est combinée avec celle-ci pour définir une cavité de réception d'une carte mémoire standard de taille inférieure comprenant une pluralité d'éléments de contact. Une pluralité de bornes conductrices sont montées sur la partie de logement arrière et comprennent des éléments de contact s'étendant dans la cavité pour venir en contact avec la carte de taille inférieure lorsque celle-ci est insérée dans la cavité, et des pastilles s'étendant dans la partie de logement avant pour venir en contact avec des éléments de contact adaptés sur le connecteur de carte mémoire.
