Abstract:
1. A method of connecting a terminal to a wire, comprising the steps of: forming straight inwardly-directed projecting portions respectively at first ends of a pair of clamping piece portions which are continuous with each other at a base at second ends located away from the first ends and form a wire connection portion of a terminal; locating a conductor portion of a wire on inner sides having first and second proximal portions located between the first and second ends of the pair of clamping piece portions so that the conductor portion contacts the inner sides; and pressing the pair of clamping piece portions over an entire periphery thereof into a circular shape so as to extend in a peripheral direction, wherein said steps are performed in the stated order; wherein said forming step includes the steps of: forming a first one of the projecting portions of the pair of clamping piece portion to be shorter than a second one of the projecting portion; bending the first one of the projecting portion inwardly at a deep angle with respect to one of the first ends of the pair of the clamping piece portions; and bending the second one of the projecting portion inwardly at a shallower angle than the deep angle with respect to another one the first ends of the clamping piece portions, wherein when the pressing step is effected, the first one of the projecting portions is caused to bite into the conductor portion of the wire while the second one of the projecting portions is held in intimate contact with an outer peripheral surface of the conductor portion.
