1. Field of the Invention
The present invention relates to a conducting terminal connector and a method of fabricating the same, and more particularly, to a conducting terminal connector that employs an insulating tube and a soldering sleeve as a joining device for joining a conducting terminal and a conducting wire.
2. Description of the Related Art
In a conventional method of joining two conducting wires, an insulating adhesive tape is used to wind around conducting cores of the conducting wires that are exposed outwardly of insulating claddings of the conducting wires, in order to cause the conducting cores to connect with each other, thereby achieving electrical conduction therebetween. However, due to the use of adhesive tape, the conducting wires may be easily affected by environmental factors, which cause electric leakage or problems related to dampness. In response to these problems, U.S. Pat. No. 4,883,925 proposed a conducting wire connecting device 100. Referring to

To address the problems in the prior art, the present invention provides a conducting terminal connector and a method for fabricating the same. The conducting terminal connector comprises a conducting terminal, an insulating tube and a soldering sleeve, for joining the conducting terminal and a conducing wire. The conducting wire includes a conducting core and an insulating cladding enclosing the conducting core. The insulating tube is shrunken and deformed when heated to a temperature higher than a first temperature, and has a melting point at a second temperature. The conducting terminal includes a first end accommodated in the insulating tube, and a second end opposite to the first end and exposed outwardly for connecting to an external conducting contact point. The first end is bent to form a longitudinal elongation with an opening facing upward. The soldering sleeve is made by a casting method so as to form a corrugated and seamless outer surface on an outer periphery of the soldering sleeve. The soldering sleeve has a melting point at a third temperature between the first temperature and the second temperature. The soldering sleeve is placed on the longitudinal elongation of the conducing terminal so as to allow insertion of the conducting core with the stripped-off insulating cladding. When heating an outer part of the insulating tube that corresponds to the soldering sleeve to heat the insulating tube to a predetermined temperature between the first temperature and the third temperature, an inner part of the insulating tube that corresponds to the soldering sleeve is shrunken to lodge in the outer corrugated surface of the soldering sleeve, thereby forming the conducting terminal connector.
Therefore, a principal object of the present invention is to provide a conducting terminal connector having a conducting terminal, a soldering sleeve and an insulating tube, wherein the soldering sleeve has a corrugated and seamless outer surface formed on its outer periphery by a casting method, thereby to obtain better connection between the soldering sleeve and the insulating tube because an inner part of the insulating tube is shrunken to lodge in the corrugated and seamless outer surface of the soldering sleeve when heating an outer part of the insulating tube.
Another object of the present invention is to provide a conducting terminal connector having a conducting terminal, a soldering sleeve and an insulating tube, wherein the soldering sleeve is formed to be seamless by a casting method so as to have better strength and stiffness. It is easier to place the soldering sleeve in the insulating tube. The manufacturing method of the conducting terminal connector is also easier.
