Connecting structure of crimp terminal and electric wire
A structure for connecting a crimp terminal and an electric wire includes: a crimp terminal that includes a conductor crimping portion and a coating crimping portion serially and includes an electric wire connector that is to be crimped to the electric wire; and a water stop sheet having an opening for bringing a conductor into contact with the conductor crimping portion, and laid between the electric wire connector and the electric wire. When a joint is swaged and crimped, the swaged and crimped joint has a second included angle θ 2 between the bottom plate and a second line that is larger than a first included angle θ 1 between the bottom plate and a first line in a cross section that is perpendicular to a bottom plate of the electric wire connector and that includes an electric wire axial line.
1. A connecting structure of a crimp terminal and an electric wire, the connecting structure comprising:
a crimp terminal that includes a conductor crimping portion and a coating crimping portion serially, the conductor crimping portion being configured to crimp a conductor of the electric wire, the coating crimping portion being configured to crimp the electric wire from an outer circumference of a coating, the crimp terminal including an electric wire connector configured to be crimped to the electric wire; and
a water-proofing material having a size capable of surrounding the conductor that is to be crimped and the coating, and laid between the electric wire connector and the electric wire, wherein
the water-proofing material protrudes to the outer circumference of the coating from a rear end of the coating crimping portion that has been swaged and crimped, and
the water-proofing material has an opening for bringing the conductor into contact with the conductor crimping portion.
2. The connecting structure of the crimp terminal and the electric wire according to claim 1 , wherein
the water-proofing material protrudes from a front end of the conductor crimping portion that has been swaged and crimped.
3. The connecting structure of the crimp terminal and the electric wire according to claim 1 , wherein
a size of the water-proofing material is equal to or larger than a size of the electric wire connector.
