Abstract
An electric wire with a terminal includes: an electric wire; and a crimp terminal including a terminal connection part on a front side and an electric wire connection part on a rear side, the terminal connection part configured to be electrically connected to a counterpart terminal, the electric wire connection part being wound around and crimped onto the electric wire, in which a bent part is formed on a bottom face of the electric wire connection part, the bent part being bent toward a side for causing a rear end of the bottom face to be closer to a center axis of the electric wire connection part.
Claims9
An electric wire with a terminal comprising:
- an electric wire;
- and
- a crimp terminal including a terminal connection part on a front side and an electric wire connection part on a rear side, the terminal connection part being configured to be electrically connected to a counterpart terminal, the electric wire connection part being wound around and crimped onto the electric wire, wherein
- the electric wire connection part includes a bottom part, a first barrel piece part, and a second barrel piece part, the first barrel piece part and the second barrel piece part projecting from ends in a width direction of the bottom part, and
- a bent part is formed on a bottom face of the bottom part, the bent part being bent toward a side for causing a rear end of the bottom face to be closer to a center axis of the electric wire connection part.
A terminal crimping apparatus comprising:
- a terminal supply device configured to supply a terminal chain body including a plurality of crimp terminals arranged in parallel, a coupling piece extending along an arrangement direction of the crimp terminals, and a connecting part connecting one end of the crimp terminal with the coupling piece;
- a first die including a supporting surface configured to support the crimp terminal supplied by the terminal supply device, and a first edge part arranged at one end of the supporting surface;
- a second die arranged to be opposed to the supporting surface, and configured to sandwich the crimp terminal and the electric wire between the second die and the supporting surface to crimp the crimp terminal onto the electric wire while moving relatively to the supporting surface;
- and
- a terminal cut body arranged to be adjacent to the first die and including a second edge part corresponding to the first edge part, wherein
- the terminal cut body moves relatively to the first die in the same direction as a moving direction of the second die, and cuts off a boundary between the connecting part and the crimp terminal with the second edge part in cooperation with the first edge part, and
- an end of the supporting surface on the first edge part is inclined toward the second die as coming closer to the first edge part.
