Crimp terminal and structure for connecting crimp terminal and wire
View Patent ↗A crimp terminal includes a wire connector that crimps a conductor crimping portion and a coating crimping portion in such a manner as to enclose a range continuous from the front end of the conductor crimping portion to the rear end of the coating crimping portion; and a wire holding portion that is formed integrally with the coating crimping portion on the side opposite to the conductor crimping portion via a junction portion and holds the electric wire from the outer circumference of the coating. The junction portion is integrally formed in a manner continuous with a bottom plate of the coating crimping portion. On the inner surface of the junction portion, a convex portion is provided in a protruding manner for crimping the wire connector to the electric wire and bending the electric wire.
1. A crimp terminal comprising:
a wire connector that crimps a conductor crimping portion and a coating crimping portion in such a manner as to enclose a range continuous from a front end of the conductor crimping portion to a rear end of the coating crimping portion, the conductor crimping portion crimping a conductor exposed portion in which a conductor is exposed by removing a coating at a terminal end of an electric wire, the coating crimping portion crimping a part of the coating left at the terminal end of the electric wire; and
a wire holding portion that is formed integrally with the coating crimping portion on a side opposite to the conductor crimping portion via a junction portion and holds the electric wire from an outer circumference of the coating, wherein
the junction portion is integrally formed in a manner continuous with a bottom plate of the coating crimping portion, and
on an inner surface of the junction portion, a convex portion is provided in a protruding manner for crimping the wire connector to the electric wire and bending the conductor and the coating of the electrical wire.
2. The crimp terminal according to claim 1 , further comprising:
a water-proofing material disposed between the wire connector and the electric wire, wherein
the water-proofing material has an opening for bringing the conductor exposed portion into contact with the conductor crimping portion and has such a size as to surround the part of the coating and the conductor exposed portion that are crimped by the wire connector.
3. A structure for connecting a crimp terminal and an electric wire, the structure comprising:
an electric wire including a conductor, a coating that covers the conductor, and a conductor exposed portion in which the conductor is exposed by removing the coating at a terminal end; and
a crimp terminal in which a wire connector is formed, the wire connector including a conductor crimping portion to which the conductor exposed portion at the terminal end of the electric wire is crimped and a coating crimping portion to which a part of the coating left at the terminal end of the electric wire is crimped, wherein
in the wire connector, the conductor crimping portion and the coating crimping portion are crimped to the terminal end of the electric wire in such a manner as to enclose a range continuous from a front end of the conductor crimping portion to a rear end of the coating crimping portion,
the crimp terminal further includes a wire holding portion that is formed integrally with the coating crimping portion on a side opposite to the conductor crimping portion via a junction portion and holds the electric wire from an outer circumference of the coating,
the junction portion is integrally formed in a manner continuous with a bottom plate of the coating crimping portion, and
on an inner surface of the junction portion, a convex portion is provided in a protruding manner for crimping the electric wire to the wire connector and bending the conductor and the coating of the electrical wire.
4. The structure for connecting a crimp terminal and an electric wire according to claim 3 , further comprising:
a water-proofing material disposed between the wire connector and the electric wire, wherein
the water-proofing material has an opening for bringing the conductor exposed portion into contact with the conductor crimping portion and has such a size as to surround the part of the coating and the conductor exposed portion that are crimped by the wire connector.
