Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
130 words
A method of fabricating a socket type electrical contact for use in an electrical connector comprising the steps of: plating a strip of beryllium copper with nickel; plating only one end portion of one side of said strip with a first layer of gold to a thickness of at least 0.625 micrometers; stamping, from said sheet a rectangularly shaped piece having a plurality of fingers extending longitudinally from one end of said piece; forming said rectangular piece into a tubular form; heating said tubular form in a vacuum furnace at a pressure below 50 microns for at least 2 hours and 15 mintues at a temperature of about 489 degrees centigrade; and plating the entire tubular form with a second layer of gold to a thickness less than 0.250 micrometers.
Claim 2
Independent Claim
130 words
A method of fabricating a socket type electrical contact for use in an electrical connector comprising the steps of: plating a strip of beryllium copper with nickel; plating only one end portion of one side of said strip with a first layer of gold to a thickness of at least 0.625 micrometers; stamping, from said sheet a rectangularly shaped piece having a plurality of fingers extending longitudinally from one end of said piece; forming said rectangular piece into a tubular form; heating said tubular form in a vacuum furnace at a pressure below 50 microns for at least 2 hours and 15 mintues at a temperature of about 489 degrees centigrade; and plating the entire tubular form with a second layer of gold to a thickness less than 0.250 micrometers.
Claim 3
Dependent Claim
37 words
The method as recited in claim 1 including the steps of: placing an intermediate sleeve over said tubular form; and placing an outer sleeve over a portion of the intermediate sleeve that surrounds the plurality of fingers.
Claim 4
Independent Claim
25 words
The method as recited in claims 1 or 2 wherein the first layer of gold comprises a band along each end portion of said strip.
Claim 5
Dependent Claim
37 words
The method as recited in claim 1 including the steps of: placing a sleeve over the portion of the tubular form having the fingers; and placing another sleeve over the opposite end portion of said tubular form.
