Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
94 words
A self-contained solder delivery device comprising: (a) a tubular housing having tubular side walls, one end of which is closed and the other end of which contains an opening; (b) a quantity of solder and flux positioned within the housing toward the open end thereof; and (c) means within the housing between said solder and said closed end for pressuring the solder through said opening when the solder is molten, and wherein said solder, flux, and pressuring means substantially fill the housing so that a substantial length of a conductor cannot be inserted therein.
Claim 2
Dependent Claim
94 words
A self-contained solder delivery device comprising: (a) a tubular housing having tubular side walls, one end of which is closed and the other end of which contains an opening; (b) a quantity of solder and flux positioned within the housing toward the open end thereof; and (c) means within the housing between said solder and said closed end for pressuring the solder through said opening when the solder is molten, and wherein said solder, flux, and pressuring means substantially fill the housing so that a substantial length of a conductor cannot be inserted therein.
Claim 3
Dependent Claim
27 words
A device in accordance with claim 1, wherein the means for pressuring the solder through the opening when the solder is molten comprises a piston and driver.
Claim 4
Dependent Claim
27 words
A device in accordance with claim 2, wherein the piston is capable of expanding radially when heated to a temperature below the melting temperature of the solder.
Claim 5
Dependent Claim
15 words
A device in accordance with claim 2, wherein the driver comprises a gas generating substance.
Claim 6
Dependent Claim
133 words
A connector for an electrical conductor, comprising: (i) at least one metallic tubular sleeve having at least one open end sized to receive an electrical conductor, and (ii) a self-contained solder delivery device comprising: (a) a tubular housing having tubular side walls, one end of which is closed and the other end of which contains an opening extending at least partially thereacross; (b) a quantity of solder and flux positioned within the housing such that said quantity extends across said opening; and (c) means within the housing between said solder and said closed end for pressuring the solder through said opening when the solder is molten; said delivery device being joined to the sleeve so that the molten solder is pressured between the sleeve and the conductor to form a solder joint therebetween.
Claim 7
Dependent Claim
133 words
A connector for an electrical conductor, comprising: (i) at least one metallic tubular sleeve having at least one open end sized to receive an electrical conductor, and (ii) a self-contained solder delivery device comprising: (a) a tubular housing having tubular side walls, one end of which is closed and the other end of which contains an opening extending at least partially thereacross; (b) a quantity of solder and flux positioned within the housing such that said quantity extends across said opening; and (c) means within the housing between said solder and said closed end for pressuring the solder through said opening when the solder is molten; said delivery device being joined to the sleeve so that the molten solder is pressured between the sleeve and the conductor to form a solder joint therebetween.
Claim 8
Dependent Claim
27 words
A device in accordance with claim 5, wherein the means for pressuring the solder through the opening when the solder is molten comprises a piston and driver.
Claim 9
Dependent Claim
27 words
A device in accordance with claim 6, wherein the piston is capable of expanding radially when heated to a temperature below the melting temperature of the solder.
Claim 10
Dependent Claim
15 words
A device in accordance with claim 6, wherein the driver comprises a gas generating substance.
Claim 11
Dependent Claim
18 words
A connector in accordance with claim 5, wherein said solder delivery device is located within said metallic sleeve.
Claim 12
Dependent Claim
18 words
A connector in accordance with claim 5, wherein said solder delivery device is located outside said metallic sleeve.
Claim 13
Dependent Claim
31 words
A connector in accordance with claim 10, wherein said solder delivery device further comprises an outlet and said metallic sleeve is provided with a hole in which said outlet is positioned.
Claim 14
Independent Claim
184 words
A method for connecting an electrical conductor, comprising: (I) selecting a connector comprising: (i) at least one metallic tubular sleeve having at least one open end sized to receive said conductor to be connected, and (ii) a self contained solder delivery device comprising: (a) a tubular housing having tubular side walls, one end of which is closed and the other end of which contains an opening extending at least partially thereacross; (b) a quantity of solder and flux positioned within the housing such that said quantity extends across said opening; and (c) means within the housing between said solder and said closed end for pressuring the solder through said opening when the solder is molten; (II) placing said conductor in said sleeve; (III) joining the self-contained solder delivery device to said sleeve so that on heating the molten solder is delivered between the conductor and the metal sleeve; (IV) heating the self-contained delivery device so that solder is delivered between the conductor and the metal sleeve; and (V) cooling to solidify the solder and form a solder joint between the conductor and metal sleeve.
Claim 15
Independent Claim
184 words
A method for connecting an electrical conductor, comprising: (I) selecting a connector comprising: (i) at least one metallic tubular sleeve having at least one open end sized to receive said conductor to be connected, and (ii) a self contained solder delivery device comprising: (a) a tubular housing having tubular side walls, one end of which is closed and the other end of which contains an opening extending at least partially thereacross; (b) a quantity of solder and flux positioned within the housing such that said quantity extends across said opening; and (c) means within the housing between said solder and said closed end for pressuring the solder through said opening when the solder is molten; (II) placing said conductor in said sleeve; (III) joining the self-contained solder delivery device to said sleeve so that on heating the molten solder is delivered between the conductor and the metal sleeve; (IV) heating the self-contained delivery device so that solder is delivered between the conductor and the metal sleeve; and (V) cooling to solidify the solder and form a solder joint between the conductor and metal sleeve.
Claim 16
Dependent Claim
26 words
