Crimped terminal
View Patent ↗In a crimp terminal ( 1 ) with a conductor crimp portion ( 11 ) having recessed serrations in the inner surface ( 11 R), circular recesses ( 20 ) as serrations are provided in an inner surface ( 11 R) of the conductor crimp portion ( 11 ) to be scattered so as to be spaced from each other before the conductor crimp portion ( 11 ) is crimped to a conductor (Wa) of an electric wire (W). A strip-shaped serration non-forming region ( 22 ) is provided in an intermediate portion in a front-back direction of the conductor crimp portion ( 11 ) and formed without the recesses ( 20 ).
1. A crimp terminal comprising:
an electrical connection portion provided in a front portion in a longitudinal direction of the crimp 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 crimp 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 comprises, in a flush inner surface of the conductor crimp portion,
circular recesses as serrations recessed from the flush inner surface of the conductor crimp portion and scattered to be spaced from each other, and
a strip-shaped serration non-forming region provided in an intermediate portion in a front-back direction of the conductor crimp portion and formed without the recesses.
2. The crimp terminal of claim 1 wherein the strip-shaped serration non-forming region has a width greater than a spacing between adjacent circular recesses.
3. A crimp terminal comprising:
an electrical connection portion provided in a front portion in a longitudinal direction of the crimp 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 crimp 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 comprises, in a flush inner surface of the conductor crimp portion,
circular recesses as serrations, recessed from the flush inner surface of the conductor crimp portion, spaced from each other in a zigzag pattern, and
a strip-shaped serration non-forming region provided in an intermediate portion in a front-back direction of the conductor crimp portion and formed without the recesses.
4. The crimp terminal of claim 3 wherein the strip-shaped serration non-forming region has a width greater than a spacing between adjacent circular recesses.
