  • Patent number: 5137478
    Abstract: This invention relates to a sealed solder wire connector assembly and method of use operable to connect to an electrical wire member. The sealed solder wire connector assembly includes 1) an electrical terminal member having a solder connector end section on one end of a main terminal body; and 2) a protective sleeve asesmbly mounted about the electrical terminal member and constructed of a heat shrink material with an adhesive coating on an inner surface thereof. The solder connector end section is of a semi-circular shape with a low temperature melt solder coating to receive the wire member thereagainst. Application of heat to the sealed solder connector assembly results in 1) melting of the solder coating into the wire member; 2) melting of the adhesive coating; 3) shrinking of the protective sleeve assembly about the wire member and the electrical terminal member; and 4) removing the heat to achieve an air tight fluid sealed solder wire connector assembly.

  • Patent number: 4883925
    Abstract: This invention relates to a sealed solder connector assembly and method of use operable to interconnect adjacent conduit wire members having exposed wire sections extended from insulated cover sections. The sealed solder connector assembly includes (1) a main support member constructed of a flexible plastic tubing; (2) a wire anchor member constructed of a low temperature melting point solder material placed interiorly and centrally of the main support member; and (3) an interior anchor coat of a temperature controlled adhesive film anchored to an interior surface of the main support member. Application of heat to the main support member results in (1) initial securing of the wire anchor assembly centrally of the main support member; (2) anchoring and sealing the main support member about the conduit wire members; and (3) melting and fusing the wire anchor member to the wire sections of the wire members.
