Electric wire with crimp terminal
View Patent ↗An electric wire with a crimp terminal which can improve a connection stability between a crimp terminal and the electric wire without making a fixing work of the crimp terminal troublesome is provided. In an electric wire with a crimp terminal in which an outer peripheral surface of a conductor portion into which a plurality of metal element wires is bundled together is covered with an insulating sheath portion into an electric wire, and the conductor portion of a terminal portion of the electric wire is exposed, and a conductor crimping portion of the crimp terminal is crimped onto the exposed conductor portion, the terminal surfaces of the plurality of metal element wires are cut in alignments so that the metal element lines extend more as the metal element lines are farther from one side portion side of the exposed conductor portion in a radial direction.
1. An electric wire with a crimp terminal, comprising:
a conductor portion including a first plurality of metal element wires and a second plurality of metal element wires, the first plurality of element wires defining an outer peripheral surface of the conductor portion into which the first and second pluralities of metal element wires are bundled together and covered with an insulating sheath portion, the conductor portion of a terminal portion of the electric wire being exposed, and the conductor portion terminating at an end surface, and
a conductor crimping portion of the crimp terminal that is crimped onto the exposed conductor portion,
wherein each of the first plurality of metal element wires terminates at a terminal end,
wherein each of the second plurality of metal element wires terminates at a terminal end that defines the end surface of the conductor portion, and
wherein the exposed conductor portion has an outside element wire folded portion configured such that each of the first plurality of metal element wires is arranged in a circumferential direction, and outermost in a radial direction with respect to the second plurality of metal element wires, and each of the first plurality of metal element wires is folded back in a direction opposite to the end surface of the conductor portion along an extension direction such that the terminal ends of the first plurality of metal element wires are spaced inwardly from the end surface of the conductor portion in the extension direction.
2. An electric wire with a crimp terminal, comprising:
a conductor portion, an outer peripheral surface of the conductor portion into which a plurality of metal element wires is bundled together being covered with an insulating sheath portion into the electric wire, the conductor portion of a terminal portion of the electric wire being exposed, and the conductor portion terminating at an end surface, and
a conductor crimping portion of the crimp terminal that is crimped onto the exposed conductor portion,
wherein the exposed conductor portion has an outside element wire folded portion configured such that the plurality of metal element wires arranged in a circumferential direction, outside in a radial direction is folded back in a direction opposite to the end surface of the conductor portion along an extension direction, and the outside wire element folded portion contacts at least one of the plurality of metal element wires that is separate from the outside wire element folded portion, and
wherein the plurality of metal element wires arranged in the circumferential direction are divided into a plurality of steps in the radial direction, and folded back.
