Abstract:
1. A structure for connecting an electric wire to a crimp terminal, the crimp terminal having a front portion having an electric connecting region that is to be connected with a counterpart terminal; and a rear portion having an electric wire connecting region that is formed so as to assume a substantially U-shaped form when viewed in cross section, and a bottom plate and a pair of electric wire crimping pieces extended upward from both side edges of the bottom plate and that are folded inward so as to wrap an end of an electric wire to be connected so as to bring the end of the electric wire into close contact with an upper surface of the bottom plate; the structure comprising: a metallic cover having a half pipe region having a circular-arc cross sectional shape at one longitudinal end thereof and an annular region having a substantially circular cross sectional shape with peripheral edges separated by a clearance gap at other longitudinal end thereof, wherein the metallic cover is fitted to a conductor exposed by removal of an insulating sheath from the end of the electric wire so that the half pipe region is situated at a leading end of the conductor so as to cover a space above the conductor; and the annular region is fitted around an outer periphery of the conductor; and wherein in a state in which the end of the electric wire equipped with the cover is set on the bottom plate of the electric wire connecting region while the conductor exposed outside an open area of the half pipe region is oriented toward the bottom plate, the pair of electric wire crimping pieces of the electric wire connecting region are folded inward and crimped so as to crimp the end of the electric wire to the electric wire connecting region along with the cover, wherein the metallic cover has at least one serration on an interior surface of the cover which extends continuously across the circular-arc cross sectional shape of the half pipe region.
