Abstract
A terminal fitting 10 includes a main body 20 to be coupled to a mating conductor, and a crimp contact section 30 rearward from the main body 20. The crimp contact section 30 is crimped on an end of a core wire 42 in a covered electrical cable 40 so as to surround the end. The core wire 42 includes a plurality of metallic strands 41 and is covered with a sheath 43 to form the covered electrical cable 40. Serrations 34 are provided on a contact surface of the crimp contact section 30 for surrounding the core wire 42. Each serration 34 is a polygonal shaped recess with which the core wire 42 engages upon crimping. Both diagonal corner portions 34C of each serration 34 are rounded. Thus, the whole periphery of an opening edge around the recess penetrates an oxide layer on a core wire.
