  • Patent number: 10008784
    Abstract: A spacer has a first cylindrical portion where a primary crimped state of a braided member is formed between the spacer and a cable. After the primary crimped state is formed, in a state in which a second flange of the terminal fitting fitted around the cable and the braided member is in contact with a first flange, a sleeve fitted around a second cylindrical portion forms a crimped state of the braided member between the sleeve and the terminal fitting at the second cylindrical portion, so that the terminal fitting is fixed to the braided member.

  • Publication number: 20180083433
    Abstract: A terminal fitting includes a cylindrical portion having a first crimping region and a second crimping region. A crimped state of a braided body extending through the terminal fitting is formed between the terminal fitting and a cable at the first crimping region such that relative movements of the terminal fitting and the braided body are prevented, and an end of the braided body is then folded back and positioned to face an outer surface of the cylindrical portion in a radial direction. The crimped state of the braided body is then formed between a sleeve and the terminal fitting at the second crimping region, so that the terminal fitting is fixed to the braided body.
