Abstract
A solder sleeve for connecting a wire to another wire or to a terminal device is formed from an alloy comprised of 42 percent tin and 58 percent bismuth that has a eutectic melt point of approximately 138° C. The wire receiving portion, at least one side of the solder sleeve is in the form of a hollow tubular member that is extruded so as to lack a longitudinal seam, the opposing side may be in one of many forms. A thermochromic dye is mixed in with a flux layer located on a portion of the outer surface of the solder sleeve, the dye designed to change from a first color to a second color at the same temperature as the melting point of the alloy. The solder sleeve may be held within a heat shrink tube.

A solder sleeve connector comprising:
- a solder sleeve having a first end in the form of a first hollow tubular member and a second end, the solder sleeve comprised of an alloy that is 42 percent tin and 58 percent bismuth and that has a eutectic melt point at a set temperature, the first hollow tubular member adapted to receive a first stripped end of a first wire therein;
- and
- a flux layer encompassing a portion of the surface of the solder sleeve, the flux layer having a thermochromic dye mixed therein, the thermochromic dye set to change from an initial color to a different final color when an adequate reflow temperature is reached or exceeded at the solder sleeve.
The solder sleeve connector wherein the first hollow tubular member is extruded thereby lacking a longitudinal seam.
A solder sleeve connector comprising:
- a solder sleeve having a first end in the form of a hollow tubular member and a second end, the solder sleeve comprised of an alloy that is 42 percent tin and 58 percent bismuth and that has a eutectic melt point at a set temperature of 138° C., the hollow tubular member adapted to receive a first stripped end of a first wire therein and wherein the first hollow tubular member s extruded thereby lacking a longitudinal seam;
- and
- a flux layer encompassing a portion of the outer surface of the solder sleeve, the flux layer having a thermochromic dye mixed therein, the thermochromic dye set to change from an initial color to a different final color whenever an adequate reflow temperature is reached or exceeded at the solder sleeve.
