  • Patent number: 6814596
    Abstract: A card connector (1, 1′) includes an insulative housing (2, 2′) defining a card receiving space (23, 23′), a number of contacts (3, 3′) retained in the housing, a metal shell (4, 4′) shielding the contacts, and an elastic locking piece (8, 8′). The elastic locking piece includes a locking portion (83, 83′) and a protruding portion (82, 82′). The metal shell defines a guide hole (41, 41′) for guiding the displacement of the protruding portion. When the elastic locking piece is biased by an inserted card (10) having a notch (18) before the locking portion engages with the notch during an earlier card insertion operation, the protruding portion is displaced in a first direction. When the locking portion engages with the notch during a later card insertion operation, the protruding portion moves in a second direction opposite to the first direction.

  • Patent number: 6764327
    Abstract: An electrical card connector (700) has a housing (2) and an end position switch (3). The end position switch includes a first spring contact (31) and a second spring contact (32). The first and second spring contacts respectively have body portions (313, 323), and contact arms (314, 324) extending from the body portions. The first spring contact has a resilient contact portion (312) slantways extending from the body portion. The second spring contact has a guide portion (318) extending downwardly from the contact arm. When an electrical card is inserted into the connector, the contact arm of the first spring contact moves onto and contacts with the contact arm of the second spring contact along the guide portion of the second spring contact.
