  • Terminal fitting
    Patent number: 6520811
    Abstract: A terminal fitting has a bottom wall (15). A curved portion (21) is folded back at a front end (15F) of the bottom wall (15). A touching portion (22) extends back from the curved portion (21) and is in contact with the bottom wall (15). A contact portion (23) extends back from the touching portion (22). The contact portion (23) is displaced resiliently about the rear end (22R) of the touching portion (22) in response to contact by a male tab (T), and a resilient restoring force of the contact portion (23) ensures high contact pressure. The curved portion (21) is not resiliently deformed when the contact portion (23) is displaced. Thus, there is no possibility of concentrating a stress on the curved portion (21) and the height of a terminal fitting can be reduced by reducing a radius of curvature of the curved portion (21).
    Type: Grant
    Filed: December 21, 2001
    Date of Patent: February 18, 2003
    Assignee: Sumitomo Wiring Systems, Ltd.

  • Joint connector
    Patent number: 6443782
    Abstract: There is provided a joint connector that allows the number of assembling process to be decreased. The connector includes a conductive metal plate (50) secured on a retainer (40). When the retainer (40) is assembled onto the housing (11), the retainer (40) engages terminals 30 in the housing (11), thereby conductively connecting the terminals 30.
