  • Patent number: 7462062
    Abstract: The present invention is to provide a terminal for a flat circuitry. The terminal assuredly crimps a conductor of the flat circuitry and provides an improved electric connection. An electric connection portion of a crimping terminal includes a bottom wall for placing a flat conductor of a FFC and a pair of conductor crimping pieces. The conductor crimping pieces are upstanding at both ends of the bottom wall for crimping the conductor. A plurality of serrations are disposed outside ends of the conductor placed on the bottom wall of the electric connection portion and arranged in series with a distance between the serrations. The conductor crimping pieces start to deform at the serrations, or the best deforming position, for crimping the conductor.

  • Publication number: 20080280510
    Abstract: An electrical contact includes a mating portion and a crimp portion connected by a transition region. The mating portion is configured to receive a mating external contact pin. The mating portion has a top wall and a bottom wall joined by opposing side walls. The top, bottom and side walls form a contact box open at one end. The contact box includes a contact beam that extends through the contact box, a front flap portion and a front aperture for insertion of the mating contact, and a back aperture adjacent to the transition region. The front flap portion protrudes partially into the front aperture forward of the contact beam to prevent a free end of the contact beam from receiving a direct impingement force when mating the electrical contact with the second electrical contact.
