Patent ID: 8870611

Claim:
A crimping terminal having an electric connection portion for connecting to a mating terminal in a front portion thereof and a wire connection portion that is caulked and connected to a terminal portion of electric wire in a rear portion thereof, wherein the wire connection portion is provided with a conductor crimping portion positioned in a front side thereof and a sheath caulking portion positioned in a rear side thereof, wherein the conductor crimping portion is formed so as to have a substantially U-shaped cross section with a bottom plate and a pair of conductor caulking pieces which are extended upwardly from both side edges of the bottom plate and bent inwardly to enclose a conductor having been exposed by removing an insulation sheath of a terminal of an electric wire to be connected thereto thereby caulking the conductor so that the conductor is in close contact with an upper surface of the bottom plate, wherein the sheath caulking portion is formed so as to have a substantially U-shaped cross section with a bottom plate and a pair of sheath caulking pieces which are extended upwardly from the both side edges of the bottom plate and bent inwardly to enclose an insulation sheath portion of a terminal of an electric wire to be connected thereto thereby caulking the insulation sheath portion so that the insulation sheath portion is in close contact with an upper surface of the bottom plate, wherein the bottom plate of the conductor crimping portion and the bottom plate of the sheath caulking portion are formed as a common bottom plate, and the conductor caulking pieces and the sheath caulking pieces are formed therebetween with a pair of continuous covering walls, the pair of continuous covering walls configured to enclose the electric wire between the conductor caulking pieces and the sheath caulking pieces, and wherein the wire connection portion is provided on an entire inner surface of the wire connection portion with concave portions or convex portions in a direction of intersecting with a longitudinal direction of the electric wire.
