Abstract
Abstract An electrical terminal having a portion of a contact section overhanging the plane of the stock is made by a method that does not weaken the terminal by the use of a slot or similar structure. A blank is stamped from sheet metal stock. Portions of the blank including the portion to overhang are formed up from the plane of the stock. At least part of the terminal base is formed up from the plane of the stock. The formed base portion is returned to the plane of the stock to rotate the contact section and move the overhanging portion to its final position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
226 words
A method of stamping and forming planar sheet metal stock to make an electrical terminal including the following structure: a terminal base portion lying generally in the plane of the stock; and a generally U-shaped contact section connected to the terminal base portion and including a bight portion and a pair of opposed and spaced apart leg portions extending from the bight portion, the bight portion lying generally perpendicular to the plane of the stock, a first of the leg portions lying generally in the plane of the stock and a second of the leg portions lying generally parallel to and spaced from the plane of the stock; said method comprising the following steps: stamping the stock to define a terminal blank including the terminal base portion, bight portion and leg portions all lying generally in the plane of the stock; forming the blank to make the contact section by leaving the bight portion generally in the plane of the stock, moving the first leg portion and at least part of the base portion to a position generally perpendicular to the plane of the stock and moving the second leg portion to a position generally perpendicular to the plane of the stock and spaced from the first leg portion; and rotating the contact section by returning the base portion generally to the plane of the stock.
Claim 2
Independent Claim

A method of stamping and forming planar sheet metal stock to make an electrical terminal including the following structure: a terminal base portion lying generally in the plane of the stock; and a generally U-shaped contact section connected to the terminal base portion and including a bight portion and a pair of opposed and spaced apart leg portions extending from the bight portion, the bight portion lying generally perpendicular to the plane of the stock, a first of the leg portions lying generally in the plane of the stock and a second of the leg portions lying generally parallel to and spaced from the plane of the stock; said method comprising the following steps: stamping the stock to define a terminal blank including the terminal base portion, bight portion and leg portions all lying generally in the plane of the stock; forming the blank to make the contact section by leaving the bight portion generally in the plane of the stock, moving the first leg portion and at least part of the base portion to a position generally perpendicular to the plane of the stock and moving the second leg portion to a position generally perpendicular to the plane of the stock and spaced from the first leg portion; and rotating the contact section by returning the base portion generally to the plane of the stock.
Claim 3
Dependent Claim
37 words
A method as claimed in claim 1 wherein the electrical terminal further includes a carrier strip lying generally in the plane of the stock and wherein said stamping step includes defining the carrier strip in the blank.
Claim 4
Dependent Claim
39 words
A method as claimed in claim 2 wherein the terminal includes a connecting portion extending between the carrier strip and the terminal base portion and said forming step includes making a bend in the blank adjacent the connecting portion.
Claim 5
Dependent Claim
15 words
A method as claimed in claim 3 wherein said rotating step includes flattening the bend.
Claim 6
Dependent Claim
19 words
A method as claimed in claim 3 wherein the bend is made at an end of the connecting portion.
Claim 7
Dependent Claim
17 words
A method as claimed in claim 1 wherein said forming step includes moving the entire base portion.
Claim 8
Dependent Claim
19 words
A method as claimed in claim 1 further comprising forming a resilient contact arm connected to each leg portion.
Claim 9
Independent Claim
77 words
A method of making an electrical terminal from planar metal stock comprising: stamping the stock to define a blank having a terminal base portion and a contact element that will overhang the plane of the stock; forming the blank to move the base portion and the contact element up from the plane of the stock; and returning the base portion to the plane of the stock in order to move the contact element to an overhanging position.
Claim 10
Independent Claim
