Abstract: A terminal connector with easy entry and manufacturing method thereof are disclosed. The terminal connector includes an insulating tube, a conductive terminal, and a soldering sleeve. The insulating tube shrinks to deform when being heated to a first temperature. The conductive terminal has a first end accommodated in the insulating tube and comprises an elongation bended to form a longitudinal opening. The soldering sleeve with a melting point at a third temperature is arranged in the elongation of the conductive terminal, while the end of the soldering sleeve extends out the elongation has a gradually enlarged portion. When the insulating tube is appropriately heated at where corresponds to the soldering sleeve by the temperature between the first temperature and the third temperature, an interior of the insulating tube shrinks to lodge the gradually enlarged portion of the soldering sleeve to form the conductive terminal with easy entry for allowing a conducting core to insert.
