Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
A method for making an electrical terminal connector including the steps of cutting a generally T-shaped blank from a conductive metal stock that exhibits work hardening properties, inwardly curling the extending portion of the top portion of the T-shaped blank to form a tubular barrel, brazing the seal formed by the curling inward of the extending portions such as to anneal the terminal, and compressing the lower portion of the T-shaped blank which forms the plane tongue opposite the barrel end beyond its elastic limit in a pressing operation so as to work harden the tongue portion to increase its hardness and to increase its resiliency.
Claim 2
Independent Claim
106 words
A method for making an electrical terminal connector including the steps of cutting a generally T-shaped blank from a conductive metal stock that exhibits work hardening properties, inwardly curling the extending portion of the top portion of the T-shaped blank to form a tubular barrel, brazing the seal formed by the curling inward of the extending portions such as to anneal the terminal, and compressing the lower portion of the T-shaped blank which forms the plane tongue opposite the barrel end beyond its elastic limit in a pressing operation so as to work harden the tongue portion to increase its hardness and to increase its resiliency.
Claim 3
Dependent Claim
20 words
The method of claim 1 further characterized in that the conductive metal that is used for the stock is copper.
Claim 4
Dependent Claim
33 words
The method of claim 1 further characterized by performing a die operation resuLting in the tongue portion of the terminal being cut to the desired shape for use in making an electrical connection.
Claim 5
Independent Claim
88 words
A method for making an electrical terminal connector including the steps of cutting a generally T-shaped blank from a conductive metal shock that exhibits work-hardening properties, inwardly curling the extending portions of the top portion of the T-shaped blank to form a tubular barrel, annealing the terminal, compressing the lower portion of the T-shaped blank which forms the plane tongue opposite the barrel end beyond its elastic limit in a pressing operation so as to work-harden the tongue portion to increase its hardness and to increase its resiliency.
Claim 6
Independent Claim
88 words
A method for making an electrical terminal connector including the steps of cutting a generally T-shaped blank from a conductive metal shock that exhibits work-hardening properties, inwardly curling the extending portions of the top portion of the T-shaped blank to form a tubular barrel, annealing the terminal, compressing the lower portion of the T-shaped blank which forms the plane tongue opposite the barrel end beyond its elastic limit in a pressing operation so as to work-harden the tongue portion to increase its hardness and to increase its resiliency.
Claim 7
Dependent Claim
15 words
The method of claim 4 further characterized by placing an annealed tube over said barrel.
Claim 8
Dependent Claim
33 words
The method of claim 5 further characterized by performing a die operation resulting in the tongue portion of the terminal being cut to the desired shape for use in making an electrical connection.
Claim 9
Dependent Claim
34 words
The method of claim 4 further characterized by and including the step of brazing the seam formed by the inward curling of the extended portion at the same time that the terminal is annealed.
