Crimped terminal
View Patent ↗A conductor crimp portion ( 11 ) before being crimped to a conductor (Wa) of an electric wire includes, in an inner surface ( 11 R) of the conductor crimp portion ( 11 ), circular recesses ( 20 ) as serrations of the conductor crimp portion ( 11 ) scattered to be spaced from each other. At an inner periphery corner portion where an inner bottom surface ( 20 A) and an inner periphery side surface ( 20 B) of each of the recesses ( 20 ) intersect with each other, a roundness portion ( 20 C) for connecting the inner bottom surface ( 20 A) with the inner periphery side surface ( 20 B) by a smooth continuous curved surface are provided.
1. A crimp terminal comprising:
an electrical connection portion provided in a front portion in a longitudinal direction of the terminal; and
a conductor crimp portion provided behind the electrical connection portion and crimped and connected to a conductor of an end of an electric wire, the conductor crimp portion having a cross section formed into a U-shape by a bottom plate and a pair of conductor crimping pieces provided to extend upwardly from both right and left side edges of the bottom plate and crimped to wrap the conductor disposed on an inner surface of the bottom plate,
wherein the conductor crimp portion before being crimped to the conductor of the end of the electric wire includes, in an inner surface of the conductor crimp portion, circular recesses as serrations scattered to be spaced from each other, and
wherein at an inner periphery corner portion where an inner bottom surface and an inner periphery side surface of each of the recesses intersect with each other, each of the recesses has a roundness portion for connecting the inner bottom surface with the inner periphery side surface by a smooth continuous curved surface.
