Abstract
Abstract A tab is die cut from an internal portion of an electrical terminal strip and is offset outwardly therefrom to accommodate one end of an enameled electrical conductor which is inserted thereunder, the tab being then pressed down to clamp the conductor to the terminal, any projecting end of the conductor being simultaneously cut off. One side of an electric power source is then coupled to the main portion of the terminal and the other side of the power source is momentarily coupled to the tab. The current flow through the tab heats it above soldering temperature with the heat burning the enamel off of the conductor end adjacent the tab and melting solder which is applied to the conductor end and to adjacent surfaces to solder the conductor to the terminal.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
125 words
A method of soldering electrical conductor ends to electrical terminals comprising the following steps: A. cutting a tab from the metal of the terminal and offsetting the tab from the plane of the terminal; B. inserting a conductor end beneath the tab to temporarily hold said conductor end; C. making an electrical connection between the main portion of the terminal and one side of an electric power source; D. making an electrical connection between the tab and the other side of said power source to cause electrical current to flow through said tab and said terminal to heat said tab and said conductor end to soldering temperature; and E. applying solder to the conductor end to solder it to the adjacent surfaces of said terminal.
Claim 2
Independent Claim
125 words
A method of soldering electrical conductor ends to electrical terminals comprising the following steps: A. cutting a tab from the metal of the terminal and offsetting the tab from the plane of the terminal; B. inserting a conductor end beneath the tab to temporarily hold said conductor end; C. making an electrical connection between the main portion of the terminal and one side of an electric power source; D. making an electrical connection between the tab and the other side of said power source to cause electrical current to flow through said tab and said terminal to heat said tab and said conductor end to soldering temperature; and E. applying solder to the conductor end to solder it to the adjacent surfaces of said terminal.
Claim 3
Dependent Claim
27 words
The method of claim 1 which includes the step of pressing the tab toward the terminal to clamp the conductor end to the terminal prior to soldering.
Claim 4
Dependent Claim
38 words
The method of claim 2 wherein a portion of said conductor end overhangs an edge of said terminal, and including the step of cutting off said overhanging end simultaneously with the pressing of the tab toward the terminal.
Claim 5
Dependent Claim
39 words
The method of claim 1 wherein said conductor is enameled and wherein sufficient current is passed through said tab to heat the tab and conductor end to a high enough temperature to remove the enamel from the conductor end.
Claim 6
Dependent Claim
31 words
The method of claim 1 and further comprising the step of forming grooves in the portion of said terminal adjacent to said offset tab to aid in accommodating said conductor end.
Claim 7
Dependent Claim
22 words
The method of claim 4 wherein the steps of cutting said tab, offsetting said tab, and forming said grooves are performed concurrently.
Claim 8
Dependent Claim
29 words
The method of claim 1 wherein a portion of said conductor end overhangs an edge of said terminal, and further comprising the step of cutting off said overhanging portion.
Claim 9
Dependent Claim
38 words
The method of claim 1 wherein said conductor end is an end of an electric coil, and wherein said step of inserting said conductor end beneath said tab also prevents the corresponding end of said coil from unwinding.
Claim 10
Dependent Claim
50 words
The method of claim 1 in which the electrical resistance of said tab is significantly higher than the resistance of the main portion of said terminal, whereby said current flow through said tab and terminal heats said tab to a significantly higher temperature than the main portion of said terminal.
Claim 11
Dependent Claim
33 words
A method as defined in claim 1 in which the power source is applied to the tab through the use of an electrode formed of material having a higher resistance than the tab.
Claim 12
Dependent Claim
48 words
A method as defined in claim 1 in which the terminal is clamped in a location remOved from the heating zone to make the electrical connection between the main portion of the terminal and one side of the power source and to simultaneously support the terminal during soldering.
