Terminal-equipped electric wire
A terminal-equipped electric wire includes an electric wire in which a core wire including a plurality of strands is covered with a covering, and a terminal fitting attached to the electric wire. The terminal fitting includes a core wire connection body physically and electrically connected to the core wire. The core wire connection body has a bottom, a pair of cantilever side walls erected from the bottom and arranged facing each other with a space therebetween, and at least one set of paired pressure contact bodies arranged facing each other with a space therebetween between the pair of side walls so as to come into pressure contact with the strands in an outermost layer of the core wire.
1. A terminal-equipped electric wire comprising:
an electric wire in which a core wire including a plurality of strands is covered with a covering; and
a terminal fitting attached to the electric wire, wherein
the terminal fitting includes a core wire connection body physically and electrically connected to the core wire,
the core wire connection body has a bottom, a pair of cantilever side walls erected from the bottom and arranged facing each other with a space therebetween, and at least one set of paired pressure contact bodies arranged facing each other with a space therebetween between the pair of side walls so as to come into pressure contact with the strands in an outermost layer of the core wire by cutting the covering of the electric wire inserted from an opening between respective free ends of the pair of side walls, and
the electric wire is provided with a welded portion in which all the strands of the core wire are directly connected to each other.
2. The terminal-equipped electric wire according to claim 1 , wherein
the welded portion is provided in an exposed portion of the core wire at an end of the electric wire.
3. The terminal-equipped electric wire according to claim 2 , wherein
the core wire has an exposed surface exposed along an end surface at the end of the electric wire, and
the welded portion is a laser welded portion in which all the strands are welded together by laser irradiation of the exposed surface of the core wire.
4. The terminal equipped electric wire according to claim 1 , wherein
the welded portion is provided at an end region of the electric wire prior of inserting it into the terminal fitting.
