摘要： A crimp terminal includes an F-type crimp portion and a C-type crimp portion. The F-type crimp portion has first and second barrel tabs, preferably with an identical length, for crimping a tip end of a complex stranded wire. The F-type crimp portion is adapted to have distal ends of the first and second barrel tabs put together and pushed into the tip end of the complex stranded wire to be crimped. The C-type crimp portion has a third barrel tab for crimping the complex stranded wire. The third barrel tab is wound in a C-form on an outer periphery of the complex stranded wire to be crimped. The arrangement provides a crimp terminal and an electric wire with crimp terminal, that prevents or reduces increases in retained resistance at a crimp portion, and can also prevent an electric wire from slipping out of a crimp terminal.

摘要： A composite twisted wire (1) which is obtained by twisting a plurality of strands. This composite twisted wire (1) includes: an aluminum-covered strand (2) that is obtained by forming a coating film (2b), which is formed of aluminum or an aluminum alloy, on the surface of a steel wire (2a); and an aluminum wire (3) that is formed of aluminum or an aluminum alloy. This composite twisted wire is reduced in weight, while exhibiting excellent tensile strength and excellent long-term stability with respect to electrical resistance. Consequently, this composite twisted wire is suitable, for example, for use as a wire harness of automobiles.
