Abstract
To manufacture a terminal fitting connected with an electric wire in which a core wire is covered with an insulating sheath, a cylindrical conductive member formed with a through hole is first provided. At least a part of the core wire of the electric wire is inserted into the through hole from a first end of the cylindrical member. Rotary swaging is performed onto at least the first end of the cylindrical member so as to caulk the inserted portion of the electric wire uniformly over a whole periphery thereof. Rotary swaging is performed onto at least a second end of the cylindrical member so as to compress radially to form a male type contact portion thereat.

A connecting structure, comprising:
- an electric wire in which a core wire is covered with an insulation sheath;
- and
- a cylindrical terminal fitting, integrally formed with a male type contact portion at a front end portion thereof by rotary swaging, the terminal fitting including a connecting portion which is electrically connected to the electric wire such that at least a part of the core wire is caulked uniformly over a whole periphery thereof by rotary swaging, wherein said rotary swaging compresses said cylindrical fitting radially inwardly to form said male type contact portion and to form said connection of the connecting portion with the electric wire.
A method of manufacturing a terminal fitting electrically connected with an electric wire in which a core wire is covered with an insulating sheath, comprising the steps of:
- providing a cylindrical conductive member formed with a through hole;
- inserting at least a part of the core wire of the electric wire into the through hole from a first end of the cylindrical member;
- performing rotary swaging onto at least the first end of the cylindrical member so as to caulk the inserted portion of the electric wire uniformly over a whole periphery thereof;
- and
- performing rotary swaging onto at least a second end of the cylindrical member so as to compress radially to form a male type contact portion thereat.
