Abstract:
The present invention is directed to a crimp contact for an aluminum stranded wire having a serration provided in an inner face of a crimping portion of the crimp contact. A ratio d/e is 0.33 or more, in which d represents a depth of a groove constituting the serration and e represents a diameter of an aluminum wire constituting the aluminum stranded wire. The number of grooves in the crimp contact is 3 or more. The present invention is also directed to a cable end structure of an aluminum stranded wire. A ratio between a sectional area of the aluminum stranded wire after crimping and a sectional area thereof before crimping is from 0.7 to 0.95.
