  • Method and apparatus for crimping an electrical terminal to an electrical wire
    Patent number: 9520668
    Abstract: A method is provided for crimping an electrical terminal to an electrical wire having electrical conductors. The method includes positioning the electrical wire and the electrical terminal between opposing crimp tooling members of a crimp tool. The method also includes pressing a crimp barrel of the electrical terminal against the electrical conductors of the electrical wire using the crimp tooling members such that the electrical conductors are mechanically and electrically connected to the crimp barrel. The crimp barrel is pressed against the electrical conductors such that at least some contact portions of metallic surfaces of at least some of the electrical conductors melt and form hot weld bonds with one or more contact portions of the metallic surface of one or more adjacent electrical conductors.
    Type: Grant
