Abstract
(EN)
An electrical connector assembly (20) for a card reader including a housing (24) having opposed major and minor sides (26, 30) defining a card receiving mouth (32), a plurality of conductive electrical terminals (36) disposed in the housing (24) and having portions (38) thereof extending into the mouth (32), and a conductive shroud (50) encircling the housing (24), the shroud (24) having inwardly spaced contact portions extending into the mouth (32) along at least one of the major sides (26) of the housing (24), the shroud contact portions being spaced from the electrical terminal portions (38) when the shroud (50) is assembled to the housing (24). The inwardly spaced contact portions can be spring fingers (54) extending into the mouth (32) from an edge (53) of the shroud (50) or dimples (254) expressed into the mouth from an outer surface of the shroud (250). At least one of the major sides (26) of the housing (24) includes a plurality of shroud contact receiving recesses (28) adapted to receive the shroud contact portions such that the shroud contact portions are closely adjacent a card receiving space (34) thereby being positioned to be either electrically engaged by corresponding raised conductive surfaces (84) on an outwardly facing conductive surface (82) of a shielded card (70) upon insertion of the shielded card into the mouth (32), or to remain spaced from surfaces of an unshielded card (170) upon inserting the unshielded card into the mouth (32).
(FR)
L'invention concerne un ensemble de connecteurs électriques (20) pour un lecteur de cartes. Celui-ci comprend un boîtier (24) ayant des côtés opposés plus grands et plus petits (26, 30) définissant une ouverture de réception de cartes (32), une pluralité de bornes électriques conductrices (36) placées dans le boîtier (24) et présentant des parties (38) s'étendant dans l'ouverture (32), et une enveloppe de protection conductrice (50) enveloppant le boîtier (24). L'enveloppe comporte des parties de contact espacées vers l'intérieur, s'étendant dans l'ouverture (32) sur au moins un des côtés plus grands (26) du boîtier (24), les parties de contact de l'enveloppe étant espacées des parties de bornes électriques (38) lorsque l'enveloppe (50) est assemblée au boîtier (24). Les parties de contact espacées vers l'intérieur peuvent être des doigts à ressort (54) s'étendant dans l'ouverture (32) à partir d'un bord (53) de l'enveloppe (50) ou des bosses (254) débordant dans l'ouverture à partir d'une surface extérieure de cette enveloppe. Au moins un des côtés plus grands (26) du boîtier (24) comprend une pluralité d'évidements (28) prévus pour recevoir des contacts d'enveloppes et adaptés pour recevoir les parties de contact de l'enveloppe. Ainsi, ces dernières sont adjacentes à un espace de réception de carte (34), et sont positionnées pour être mises en prise électriquement avec des surfaces conductrices surélevées correspondantes (84) sur une surface conductrice orientée vers l'extérieur (82) d'une carte blindée (70) lors de l'insertion de la carte blindée dans l'ouverture (32), ou pour rester espacées des surfaces d'une carte non blindée (170) lors de l'insertion de cette dernière dans l'ouverture (32).
