DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention discloses a structure of a wire connector and the method of fabricating the same. Since some methods of fabrication and combination used within the structure have been disclosed in detail in the prior art, therefore the fabricating process of the wires or the conducting cores and the way of tying a couple of wires are not described in detail in the following description. Moreover, the diagrams included in the following are not completely drawn according to the real size and are only used to demonstrate features related to the present invention.

Referring now to FIG. 1 and FIG. 2, they are the diagrams of the wire connector provided by the present invention. The wire connector (1) assembled by an insulating tube (2) and a soldering sleeve (3) is for connecting a plurality of conducting wires (41) which are made of conducting cores (42) and insulating claddings (43) surrounding the conducting cores. Wherein, the insulating tube (2) is shrinking to deform when heated to the first temperature, and its melting point is at the second temperature. The soldering sleeve (3) with corrugated surface (32) of its external part (31) (as shown in FIG. 3) is placed in the insulating tube (2) and its melting point is the third temperature which is between the first temperature and the second temperature.

The method to fabricate the wire connector is to heat the external part (21) of the insulating tube (2) where corresponding to the soldering sleeve (2) by the temperature between the first temperature and the third temperature, and the insulating tube (2) will shrink due to its substantial properties, therefore the internal part (22) of the insulating tube (2) will lodge into the corrugated surface (32) of the soldering sleeve (3).

Referring to FIG. 3, the soldering sleeve (3) placed in the insulating tube (2) is for fabricating a wire connector (1). The melting point of it is the third temperature which is between the first temperature and the second temperature. It would be made to be corrugated on its external surface (31) (as shown in FIG. 3A), or to be corrugated both on outer surface (32) and inner surface (33) (as shown in FIG. 3B). Moreover, the soldering sleeve (3) could also be wound by a soldering wire (5), placed in the insulating tube (2), and corrugated on its external surface (52), or to be corrugated both on outer surface (52) and inner surface (53)(as shown in FIG. 3C). Every above-mentioned embodiment of the soldering sleeve (3) would have the interference with the insulating tube (2) and be more immovable.

Consequently, the wire connector made by this kind of method is better than the prior art by combination strength.

The corrugated surface (32,33,52,53) of the soldering sleeve (3) is wavy. The waveform could be of the same height or of different heights, and could be of the same pitch or of different pitches. Also, the corrugated surface (32,33,52,53) of the soldering sleeve (3) is serrate, The serration could be of the same height or of different heights, and could be of the same pitch or of different pitches. No matter what kind of the soldering sleeve (3) is, the material of it is selected from the group consisting of the tin, lead, nickel, gold, silver, copper, bismuth, and the combinations.

As shown in FIG. 4, in the use and operation of the invention, the procedure of connecting two wires comprises the following steps:

1) providing the conducting cores (42) stuck out of the wires (41);2) inserting the wires (41) into the ends of the wire connector (1);3) providing the tops of the conducting cores (42) contacting with each other in the soldering sleeve (3); and4) heating the insulating tube (2) until the temperature reaches to the third temperature.

Then, the soldering sleeve (3) will be melted to combine with the conducting core (42), and the insulating tube (2) will shrink and stick the insulating claddings (43) of the wires (41). So that, the wire connector connects the wires tightly and strictly.

It should be noted that the above-described and illustrated embodiments of the invention are not an exhaustive listing of the forms such a wire connector in accordance with the invention might take; rather, they serve as exemplary and illustrative of embodiments of the invention as presently understood. By way of example, and without limitation, many other forms of the invention are believed to exist.
