Abstract
A press-connecting terminal (1) includes a press-connecting portion (4) having press-connecting blades (9). The press-connecting blade (9) has a pair of opposed inner surfaces (9c) extending downwardly respectively from a pair of bladed, tapering guide surfaces (9a) which are slanting downwardly toward the axis of the electric wire (7), and a gap (G), formed between the pair of inner surfaces (9c), is smaller than the diameter (d) of a conductor (7b) of the electric wire (7). On the basis of at least one of the width (W) of each of the downwardly-extending inner surfaces (9c), the size of the gap (G), and the number (n) of the press-connecting blades (9), the total area (ST) of contact of the downwardly-extending inner surfaces (9c) with the conductor (7b) is set to a value greater than or equal to the cross-sectional area (&pgr;d2/4) of the conductor (7b). Therefore, an electrical resistance, developing between the conductor (7b) and each inner surface (9c), can be reduced. Accordingly, the deterioration, improper contact and so on of those members around the press-connecting portion due to heat, produced by the electrical resistance between the conductor (7b) and each press-conne…
