Abstract
Abstract A method of making an annular biased frequency interference shielding member having securement tabs for mounting between plug and receptacle shells of an electrical connector, and having folded resilient fingers having base and distal portions respectively engageable with said plug and receptacle shells under resilient pressure engagement. The folded resilient fingers are precisely dimensioned and formed about an axis such that minimal space intervals are provided between adjacent edges of adjacent resilient fingers whereby virtually 360° shielding integrity is afforded.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
102 words
In a method of forming a frequency interference shield means for use in an electrical connector, the steps of: providing a rectangular blank of conductive metal stock material; inscribing a selected pattern of securement tabs and fingers on one surface of the metal blank; chemically etching the material between said tabs and said fingers to provide fingers of precise dimensioned tapered shape; forming said securement tabs and said fingers into selected cross sectional configurations; turning said etched and formed blank about an axis to provide an annulus; and securing ends of said etched blank together with said fingers in close adjacent relation.
Claim 2
Dependent Claim
102 words
In a method of forming a frequency interference shield means for use in an electrical connector, the steps of: providing a rectangular blank of conductive metal stock material; inscribing a selected pattern of securement tabs and fingers on one surface of the metal blank; chemically etching the material between said tabs and said fingers to provide fingers of precise dimensioned tapered shape; forming said securement tabs and said fingers into selected cross sectional configurations; turning said etched and formed blank about an axis to provide an annulus; and securing ends of said etched blank together with said fingers in close adjacent relation.
Claim 3
Dependent Claim
44 words
In a method as stated in claim 1 wherein the step of forming said fingers includes bending proximate and distal portions of said fingers out of the plane of said blank; folding distal portions of said fingers over said proximate portions of said fingers.
Claim 4
Dependent Claim
123 words
In a method of forming a frequency interference shield means for use in an electrical connector, the steps of: providing a rectangular blank of conductive metal stock material; providing a selected pattern on said blank of a band extending the length of said blank and spaced fingers extending laterally from one side of the band; forming each of said fingers into a selected cross-sectional shape; turning said band and fingers about an axis to provide an annulus wherein said band lies in a cylindrical surface generated by moving a line parallel to and spaced from said axis and said fingers lie in surfaces generated by moving lines inclined to said axis and in opposite directions; and securing together end portions of said band.
Claim 5
Dependent Claim
123 words
In a method of forming a frequency interference shield means for use in an electrical connector, the steps of: providing a rectangular blank of conductive metal stock material; providing a selected pattern on said blank of a band extending the length of said blank and spaced fingers extending laterally from one side of the band; forming each of said fingers into a selected cross-sectional shape; turning said band and fingers about an axis to provide an annulus wherein said band lies in a cylindrical surface generated by moving a line parallel to and spaced from said axis and said fingers lie in surfaces generated by moving lines inclined to said axis and in opposite directions; and securing together end portions of said band.
Claim 6
Dependent Claim
18 words
In a method as claimed in claim 3 including the step of providing securing elements for said band.
Claim 7
Dependent Claim
23 words
A method as claimed in claim 3 wherein the step of turning said band occurs relative to a cylindrical surface on a connector.
Claim 8
Dependent Claim
47 words
A method as claimed in claim 3 wherein the step of providing a selected pattern of fingers on said blank includes. shaping said spaced fingers whereby when said band and fingers are turned at a selected radius about an axis, the spaces between said fingers become minimal.
Claim 9
Dependent Claim
38 words
A method as claimed in claim 3 wherein the step of providing a selected pattern on said blank includes inscribing said pattern on said blank, and chemically etching material from the blank in accordance with said inscribed pattern.
Claim 10
Dependent Claim
30 words
A method as claimed in claim 3 wherein the step of providing a selected pattern on said band includes shaping said fingers with a narrow portion adjacent to said band.
Claim 11
Dependent Claim
116 words
In a method of forming a frequency interference shield means for use in an electrical connector, the steps of: providing a rectangular blank of conductive metal stock material; removing portions of said stock material to define a band and spaced fingers of selected shape; forming said fingers into a selected cross-sectional configuration in which proximate and distal portions of said fingers relative to said band are bent out of the plane of said blank; folding distal portions of said fingers over the proximate portions of said fingers; turning said formed blank about an axis at a selected radius to provide an annulus; and securing ends of said band with said fingers in minimal spaced adjacent relation.
Claim 12
Dependent Claim
116 words
