Abstract
Abstract Complementary male and female connectors are provided for shielded cables such as audio cables. Each connector comprises inner and outer sheet metal conductors with a sheet of insulation laminated to the outer conductor and located between the two conductors to insulate the two conductors. Each connector has portions for crimping respectively the center conductor and shield of a shielded cable. A method of making the connector is provided whereby a sheet of metal, a part of which has the insulating sheet laminated thereto, may be blanked and folded to bring together an outer laminated conductor part and an inner non-laminated conductor part so that the insulation is sandwiched between the two conductor parts, following which the inner and outer parts are shaped into a configuration which includes a tubular body having a longitudinal seam.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
167 words
In a method of making an electric connector for a cable that has an inner wire conductor and an outer conductive shield for the inner wire conductor, the steps comprising: providing a sheet of electrical conductor material having a layer of insulation laminated over a portion thereof, blanking in said sheet in a form that includes in a first part an outer body blank portion and a shield-gripping blank portion, and in a second part a wiregripping blank portion and an inner body blank portion, said first part including the laminate and the second part excluding the laminate, folding said form to bring said inner body blank portion and said outer body blank portion together and with said layer of insulation between said inner and outer body blank portions, and thereafter shaping said folded form into a connector having a generally tubular body in which the inner and outer body blank portions form generally tubular conductive members that are separated by a generally tubular shaped insulating layer.
Claim 2
Dependent Claim
167 words

Claim 3
Dependent Claim
51 words
A method according to claim 1 in which said one part further includes a backing portion joining the shield-gripping blank portion and the outer body blank portion, said backing portion containing said insulating layer, and said folding operation brings said wire-gripping blank portion onto the insulating layer of said backing portion.
Claim 4
Dependent Claim
26 words
A method according to claim 1 in which said first part also has a region that excludes said laminate, said region including the shield-gripping blank portion.
Claim 5
Dependent Claim
39 words
A method according to claim 3 in which said second part is joined to said first part in said form at said region, and the juncture between the first and second part is severed subsequent to the folding operation.
Claim 6
Dependent Claim
27 words
A method according to claim 1 including the step of striking out at least one lance from a portion of said first part that includes said laminate.
Claim 7
Dependent Claim
106 words
In a method of making an electric connector, the steps of providing a blank having a sheet of electrical conductor material with a layer of insulation laminated over only a portion thereof, folding the blank so that a part of the sheet that is free of said insulation is brought face-to-face against a part of the sheet that contains the insulation layer and with the insulating layer being sandwiched between two conductive portions of the sheet, and forming the two portions and insulating layer into a connector having a tube-like portion with a longitudinal seam and with the two portions being electrically insulated from each other.
Claim 8
Dependent Claim
106 words
