Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
171 words
A sealed solder connector assembly operable to receive an electrical wire member for connection thereto, comprising: a) an electrical terminal member including a main terminal body, a connector end section integral with one end of said main terminal body operable for electrical connection to an external member, and a solder connector end section integral with another opposed end of said main terminal body; b) said solder connector end section includes a semi-circular shaped solder receptacle portion having a solder layer to receive the wire member thereon for connection thereto; and c) a protective sleeve assembly of a heat-shrinkable material mounted about said main terminal body and said solder connector end section; whereby the application of heat about an exterior surface of said protective sleeve assembly causes same to shrink into an air tight fit over said main terminal body, said solder connector end section, and the wire member enclosed thereby and said solder layer first melts, fuses with the wire member, and then cools to form a solid, soldered electrical connection.
Claim 2
Dependent Claim
171 words
A sealed solder connector assembly operable to receive an electrical wire member for connection thereto, comprising: a) an electrical terminal member including a main terminal body, a connector end section integral with one end of said main terminal body operable for electrical connection to an external member, and a solder connector end section integral with another opposed end of said main terminal body; b) said solder connector end section includes a semi-circular shaped solder receptacle portion having a solder layer to receive the wire member thereon for connection thereto; and c) a protective sleeve assembly of a heat-shrinkable material mounted about said main terminal body and said solder connector end section; whereby the application of heat about an exterior surface of said protective sleeve assembly causes same to shrink into an air tight fit over said main terminal body, said solder connector end section, and the wire member enclosed thereby and said solder layer first melts, fuses with the wire member, and then cools to form a solid, soldered electrical connection.
Claim 3
Dependent Claim
132 words
A sealed solder wire connector assembly connectable to an exposed electrical conductor wire found in an electrical wire member, comprising: a) a protective sleeve assembly constructed of heat-shrinkable tubing material of a size to receive the wire member; b) an electrical terminal member including a main terminal body having a solder connector end section; c) said solder connector end section of semi-circular shape in transverse cross section having a solder layer on an inner concave surface to receive, support, and contact an outer surface of the conductor wire; and d) said protective sleeve assembly mounted about said solder connector end section; whereby the application of heat about an exterior of said protective sleeve assembly shrinks same about said electrical terminal member and the wire member to achieve an air tight electrical connection.
