There is disclosed a conducting terminal connector which comprises an insulating tube, a conducting terminal and a soldering sleeve. The conducting terminal has a first end received in the insulating tube and a second end opposite to said first end, and the second end is exposed outwardly for connecting an external conducting contact point so that the first end is bent to form a longitudinal elongation with an opening facing upward. The soldering sleeve is formed by a casting method so as to form a corrugated surface on the outer periphery thereof, and has a melting point in which a heat source is applied to an outer part of the insulating tube so that an inner part of the insulating tube is shrunken to lodge in the outer corrugated surface of the soldering sleeve thereby forming the conducting terminal connect.
