  • Patent number: 6782608
    Abstract: In a mold for pressing an electric-wire clamping portion of a terminal, a lower side-wall mold part and an upper side-wall mold part are provided for pressing side walls connected to the electric-wire clamping portion. A pressure face substantially continuously connected to a pressure face of an upper conductor mold part is provided on one end side of the upper side-wall mold part. A taper face is provided on the other end side of the upper side-wall mold part so as to be enlarged toward the other end. Accordingly, side walls pressed between the lower side-wall mold part and the upper side-wall mold part are deformed so that the quantity of deformation at one end is near the quantity of compressive deformation of the electric-wire clamping portion and so that the quantity of deformation is reduced gradually toward the other end side. Thus, local stress concentration is not caused in the side walls so that cracks are prevented from occurring in the side walls.

  • Patent number: 6375503
    Abstract: The connector includes a connector housing having a resilient locking arm for locking a terminal and a holder having an extended piece inserted into an insertion space of the connector housing. In an incomplete insertion state of the terminal, the locking arm deflects so that a free end surface of the locking arm protrudes from an inner wall of the insertion space to cause the extended piece to abut against the free end surface of the locking arm. Meanwhile, in a complete insertion state of the terminal, the extended piece is inserted into the insertion space to lie over the locking arm. The extended piece is longitudinally inclined toward the locking arm so that the extended piece can slidingly contact the inner wall of the insertion space.
