<p>Disclosed is an electric wire connection method wherein, regarding cables (13, 14) which have a core having a diameter larger than that of a core that can be crimped by a wire barrel (18), the diameter of a core (16) is reduced to a diameter suitable for crimping the wire barrel (18) around the core, by an ultrasonic treatment in which ultrasonic energy is applied to the core (16) while the core (16) is pressurized, and thereafter, the core (16) of each cable (13, 14) having a core size reduced by the ultrasonic treatment is swaged by a pair of crimping pieces (18B) of a terminal fitting (15), to crimp or pressure-bond the terminal fitting around the core. Regarding cables (11, 12) which have a core that can be crimped by the wire barrel (18), the core (16) of each cable (11, 12) is swaged by a pair of crimping pieces (18B) of the terminal fitting (15), to crimp the terminal fitting around the core.</p> |
