Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
172 words
An electrical contact terminal which is formed from sheet stock metal of a given thickness, said terminal comprising: a generally U-shaped ferrule-forming portion which is adapted to be crimped onto a conductor, said ferrule-forming portion having a web and sidewalls, a blade portion extending from said ferrule-forming portion, said blade portion comprising a first flat strip section which is integral with, and which extends from, said web, said first strip being reversely folded at the end of said blade to define a second flat strip section which extends towards said Ferrule-forming portion, said second flat strip section extending substantially parallel to, and being spaced from, said first flat strip section, the marginal edge portions of said first and second flat strip sections on each side of said sections being reversely bent and tucked between said first and second flat strip sections whereby said blade has an effective solid metal thickness which is equal to four times said given thickness and said ferruleforming portion has the same thickness as said sheet metal stock.
Claim 2
Dependent Claim
172 words
An electrical contact terminal which is formed from sheet stock metal of a given thickness, said terminal comprising: a generally U-shaped ferrule-forming portion which is adapted to be crimped onto a conductor, said ferrule-forming portion having a web and sidewalls, a blade portion extending from said ferrule-forming portion, said blade portion comprising a first flat strip section which is integral with, and which extends from, said web, said first strip being reversely folded at the end of said blade to define a second flat strip section which extends towards said Ferrule-forming portion, said second flat strip section extending substantially parallel to, and being spaced from, said first flat strip section, the marginal edge portions of said first and second flat strip sections on each side of said sections being reversely bent and tucked between said first and second flat strip sections whereby said blade has an effective solid metal thickness which is equal to four times said given thickness and said ferruleforming portion has the same thickness as said sheet metal stock.
Claim 3
Dependent Claim
196 words
A strip of electrical contact terminals, said terminals being in side-by-side spaced-apart relationship, each of said terminals comprising: a generally U-shaped ferrule-forming portion which is adapted to be crimped onto a conductor, said ferrule-forming portion having a web and side-walls, a blade portion extending from said ferrule-forming portion, said blade portion comprising a first flat strip section which is integral with, and which extends from, said web, said first strip being reversely folded at the end of said blade to define a second flat strip section which extends towards said ferrule-forming portion, said second flat strip section extending substantially parallel to, and being spaced from, said first flat strip section, the marginal edge portions of said first and second flat strip sections one each side of said sections being reversely bent and tucked between said first and second flat strip sections, said ferrule-forming portion of each terminal having a developed width which is sbustantially equal to the pitch of said strip and which is greater than the width of said blade portion, and adjacent terminals of said strip being connected by connecting neck sections whereby, said terminals are spaced apart along the length of said strip.
Claim 4
Dependent Claim
196 words
A strip of electrical contact terminals, said terminals being in side-by-side spaced-apart relationship, each of said terminals comprising: a generally U-shaped ferrule-forming portion which is adapted to be crimped onto a conductor, said ferrule-forming portion having a web and side-walls, a blade portion extending from said ferrule-forming portion, said blade portion comprising a first flat strip section which is integral with, and which extends from, said web, said first strip being reversely folded at the end of said blade to define a second flat strip section which extends towards said ferrule-forming portion, said second flat strip section extending substantially parallel to, and being spaced from, said first flat strip section, the marginal edge portions of said first and second flat strip sections one each side of said sections being reversely bent and tucked between said first and second flat strip sections, said ferrule-forming portion of each terminal having a developed width which is sbustantially equal to the pitch of said strip and which is greater than the width of said blade portion, and adjacent terminals of said strip being connected by connecting neck sections whereby, said terminals are spaced apart along the length of said strip.
Claim 5
Independent Claim
183 words
A method of manufacturing blade type contact terminals from metal strip stock of a given thickness, said terminals having blade portions of predetermined width w and having U-shaped ferrule-forming portions of developed width w'' where w'' is greater than w , said method comprising the steps of: feeding strip metal strip stock having a width which is substantially equal to, and slightly greater than, twice the length of one of said terminals through a stamping and forming die, forming side-by-side terminal blanks having a width which is substantially equal to w'' from said strip stock by shearing partially across said stock , forming said ferrule-forming portions of each blank on one side of said strip stock, bending remaining marginal edge portions of each blank inwardly towards the center of the blank to reduce the effective width of each said remaining portions to w, and folding a portion of each blank at a location intermediate the ends of said blank towards said ferrule-forming portion to provide a terminal blade portion of quadruple metal stock thickness in combination with a ferrule-forming portion of stock thickness.
