Abstract
Abstract A connector is disclosed which is made from a plurality of electrical contacts, each of which is a resilient spring, spaced along a continuous web of insulative material which serves to locate the contacts in desired positions and provides an insulation back or cover for the contacts. The method and apparatus for making the subject laminated connector is also disclosed. The plurality of contacts are first formed from a continuous strip of metal, an insulative web is laminated to the metal contacts, and the laminated connector is bent by a continuous roller or die forming operation to desired curvilinear arcuate shapes. Discrete lengths of contacts formed together with the carrier strip are broken away or otherwise separated from the carrier strip either prior to or after the bending operation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
167 words
A method for making a free standing and self-supporting multi-terminal electrical connector, comprising the steps of: cutting a plurality of elongated contacts from a continuous sheet of electrically conductive resilient spring material; laminating at least one continuous web of flexible insulative support material to intermediate portions of each of said contacts to hold them in fixed parallel spaced relationship, each said contact having at least one end projecting beyond a marginal edge of said web, said web being sufficiently rigid to prevent relative flexure between adjacent contacts while allowing individual outward flexing of the free ends of the contacts; and bending portions of said metal contacts into permanent curvilinear shapes to define at least one substantially U-shaped end portion adapted to grippingly receive a mating member therein, said contacts being separated from one another lengthwise along said insulative support material, said contacts being of sufficient metal thickness to be free standing and self-supporting and to provide resilient spring action for applying pressure at said contact end portions.
Claim 2
Independent Claim
167 words
A method for making a free standing and self-supporting multi-terminal electrical connector, comprising the steps of: cutting a plurality of elongated contacts from a continuous sheet of electrically conductive resilient spring material; laminating at least one continuous web of flexible insulative support material to intermediate portions of each of said contacts to hold them in fixed parallel spaced relationship, each said contact having at least one end projecting beyond a marginal edge of said web, said web being sufficiently rigid to prevent relative flexure between adjacent contacts while allowing individual outward flexing of the free ends of the contacts; and bending portions of said metal contacts into permanent curvilinear shapes to define at least one substantially U-shaped end portion adapted to grippingly receive a mating member therein, said contacts being separated from one another lengthwise along said insulative support material, said contacts being of sufficient metal thickness to be free standing and self-supporting and to provide resilient spring action for applying pressure at said contact end portions.
Claim 3
Dependent Claim
58 words
A method according to claim 1 wherein said contacts are cut from a continuous sheet of material and are initially connected to at least one continuous, common carrier strip; and removing said carrier strip from said contacts after said laminating and bending steps leaving said contacts independent of one another and fixedly spaced along the insulative support material.
Claim 4
Dependent Claim
58 words
The method as recited in claim 1, wherein said step of bending further includes the steps of: passing said contacts and said web of insulative material between successive pairs of forming rollers which bend said contacts into curvilinear leaf springs; and maintaining the ends of said leaf springs in mutual alignment to provide a row of electrical terminals.
Claim 5
Dependent Claim
28 words
The method as recited in claim 3, further including the step of: providing recessed clearances between said pairs of rollers for receipt of the web of insulative material.
Claim 6
Dependent Claim
43 words
The method as recited in claim 3, further including the steps of: passing said contacts between said pairs of rollers in a direction lengthwise of said carrier strip; and aligning said contacts by said carrier strip during passage between said series of rollers.
Claim 7
Dependent Claim
62 words
A method according to claim 1, wherein said contacts are cut from a continuous sheet of material and are initially connected to at least one continuous, common carrier strip; and removing said carrier strip from said contacts after said laminating step and prior to said bending step leaving said contacts independent of one another and fixedly spaced along the insulative support material.
