  • Patent number: 10355373
    Abstract: A crimp terminal included in a wire harness includes an electrical connecting portion, a conductor caulking portion, and a coat caulking portion. The conductor caulking portion includes a first base to which the electrical connecting portion is joined at one side in an axial direction and to which the coat caulking portion is joined at the other side, and a pair of first barrel pieces that extend from the first base and wrap the conductor of the wire between the first base and the pair of first barrel pieces and caulked. The pair of first barrel pieces include bell-mouth portions at end portions close to the coat caulking portion. The first base has a first protrusion at a position facing base ends of the bell-mouth portions across the conductor, having a recessed portion on the conductor side and protruding away from the conductor, and extending in a crossing direction.

  • Patent number: 10103455
    Abstract: A crimp terminal includes a wire connection portion including a bottom wall portion, and a pair of side wall portions. The wire connection portion includes a core wire crimping portion provided on one end side, and to be crimped onto a core wire of a wire, and a covering crimping portion provided on another end side, and to be crimped onto a covering of the wire, and integrally covers the core wire and the covering. In the core wire crimping portion before crimping, an interval between outer wall surfaces of the pair of side wall portions is widest at an end portion on the covering crimping portion side, and in the covering crimping portion before crimping, the interval is widest at an end portion on the core wire crimping portion side.

  • Patent number: 9112297
    Abstract: A female connector housing is provided with a plurality of terminal accommodating chambers. Each of the terminal accommodating chambers is provided, on its front face, with a terminal insertion opening through which a male terminal is to be inserted. Each of the terminal accommodating chambers is provided, on its rear face, with a wire withdrawal opening. In the terminal accommodating chamber which is intended to accommodate no terminal, there are provided a first shielding wall which surrounds an erroneous-insertion allowable space allowing the male terminal to be inserted erroneously and shields the interior of the erroneous-insertion allowable space and a second shielding wall for shielding the wire withdrawal opening.
