Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
74 words
A flat metal terminal which is connected to a flat-type conductor of a flat cable by a spot weld, said terminal comprising: a contact part having a nickel plating; and a spot welding part having no nickel plating, wherein the spot welding part of said flat metal terminal which has no nickel plating is connected to said flat-type conductor by said spot weld such that the strength of said spot weld is substantially uniform.
Claim 2
Dependent Claim
74 words
A flat metal terminal which is connected to a flat-type conductor of a flat cable by a spot weld, said terminal comprising: a contact part having a nickel plating; and a spot welding part having no nickel plating, wherein the spot welding part of said flat metal terminal which has no nickel plating is connected to said flat-type conductor by said spot weld such that the strength of said spot weld is substantially uniform.
Claim 3
Dependent Claim
31 words
The flat metal terminal as claimed in claim 1, wherein said contact part has gold, tin or silver plating over said nickel plating, and said spot welding part has no plating.
Claim 4
Dependent Claim
36 words
The flat metal terminal as claimed in claim 1, wherein said contact part has gold, tin or silver plating over said nickel plating and said spot welding part is also plated with gold, tin or silver.
Claim 5
Dependent Claim
85 words
In a method of forming a flat metal terminal which is connected to a flat-type conductor of a flat cable by a spot weld, said method comprising the steps of: designating a contact part and a spot welding part of said flat metal terminal; plating the contact part with nickel; not plating the spot welding part with nickel; and spot welding said spot welding part of said flat metal terminal to said flat-type conductor such that the strength of said spot weld is substantially uniform.
Claim 6
Dependent Claim
85 words
In a method of forming a flat metal terminal which is connected to a flat-type conductor of a flat cable by a spot weld, said method comprising the steps of: designating a contact part and a spot welding part of said flat metal terminal; plating the contact part with nickel; not plating the spot welding part with nickel; and spot welding said spot welding part of said flat metal terminal to said flat-type conductor such that the strength of said spot weld is substantially uniform.
Claim 7
Dependent Claim
26 words
The method as claimed in claim 4, further including the step of further plating the contact part with gold, tin or silver over the nickel plating.
Claim 8
Dependent Claim
43 words
The method as claimed in claim 4, further including the step of plating both the contact part and the spot welding part with gold, tin or silver, said gold, tin or silver plating of said contact part taking place over said nickel plating.
Claim 9
Dependent Claim
17 words
The flat metal terminal as claimed in claim 1, wherein said terminal is formed of phosphor bronze.
Claim 10
Dependent Claim
15 words
The method as claimed in claim 4, wherein said terminal is formed of phosphor bronze.
