When crimping 7 wires with an area of 0.014 mm 2 ), the inner surface of the crimping part 1 has a side surface 5 with an area of 0.043 mm 2 ~
A copper plating layer of 0.086 mm 2 (20-40 μm thick) is applied. The plating layer 4 is further plated with 1 to 2 μm of tin to prevent rust, if necessary.

続電線の断線を生じない。 The conductive material layer 4 of the crimping portion 1 is softer and less hard than the base material of the crimping portion. Therefore, by applying a comparatively small force and butting the tips of the two side plate portions 2, 2 together to cause deformation, the space between the U-shaped electric wire conductor crimping portion 1 and the electric wire conductor 3 is filled, so that the electric wire conductor 3 is tightly held by the crimping portion 1 and also acts as a buffer material, preventing breakage of the connected electric wire.

じみ耐腐蝕性が向上する等の効果を有する。 As described above, according to the present invention, a conductive material layer having a hardness smaller than that of the base material of the crimp part is attached to the inner surface of the U-shaped electric wire conductor crimp part, and the area of the side surface of the conductive material layer is equal to that of the crimp terminal. Conductor cross-sectional area S of applicable electric wire
Since the difference between the cross-sectional area S1 and the cross-sectional area S1 of the wire conductor made of ultra-fine wire to be crimped is more than 2 and less than twice the area S2 , it is necessary to change the terminal mold and crimping tool or to create a new one. Existing crimp terminals can be used for ultra-fine wires that are even thinner than the minimum applicable wire, and the cost is low, and the hardness of the conductive material layer in contact with the wire is small, so the wire will not be damaged during crimping. It does not cause any cutting, and also has the effect of blending well with electric wires and improving corrosion resistance.
