Abstract
Abstract A method for providing a receptacle includes the steps of: providing a stamped blank having a strip-like conductor which includes longitudinal edges (7), a resilient contact plate, a connective plate having a first portion and a second portion, and at least one projection: a first bending step for bending the extension such that flat surfaces of the projection are perpendicular to flat surfaces of the resilient contact plate; a second bending step, conducted after the first bending step, for bending the first portion of said conductive plate such that flat surfaces of the resilient contact plate are perpendicular to flat surfaces of the strip-like conductor; and a third bending step, conducted after the second bending step, for bending the first portion of the connective plate such that the flat surfaces of the at least one projection are perpendicular to the flat surfaces of the strip-like conductor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
A method of shaping a receptacle, comprising the steps of: providing a connective plate (11) at one end of a strip-like conductor (1), the connective plate having a first portion (11a) disposed perpendicular to longitudinal edges (7) of said conductor and a second portion (11b) disposed parallel to the longitudinal edges; providing a stamped blank (M) having a resilient contact plate (3) extending from said second portion of said connective plate, and finger-shaped projections (5, 5') extending respectively from opposite sides of said resilient contact plate through respective extensions (4); bending said extensions in such a manner that flat surfaces of said finger-shaped projections are disposed perpendicular to flat surfaces of said resilient contact plate; subsequently bending said first portion of said connective plate in such a manner that the flat surfaces of said resilient contact plate are disposed perpendicular to flat surfaces of said strip-like conductor; and subsequently further bending the first portion of said connective plate such that the flat surfaces of the finger-shaped projections are perpendicular to the flat surfaces of said strip-like conductor.
Claim 2
Independent Claim
177 words
A method of shaping a receptacle, comprising the steps of: providing a connective plate (11) at one end of a strip-like conductor (1), the connective plate having a first portion (11a) disposed perpendicular to longitudinal edges (7) of said conductor and a second portion (11b) disposed parallel to the longitudinal edges; providing a stamped blank (M) having a resilient contact plate (3) extending from said second portion of said connective plate, and finger-shaped projections (5, 5') extending respectively from opposite sides of said resilient contact plate through respective extensions (4); bending said extensions in such a manner that flat surfaces of said finger-shaped projections are disposed perpendicular to flat surfaces of said resilient contact plate; subsequently bending said first portion of said connective plate in such a manner that the flat surfaces of said resilient contact plate are disposed perpendicular to flat surfaces of said strip-like conductor; and subsequently further bending the first portion of said connective plate such that the flat surfaces of the finger-shaped projections are perpendicular to the flat surfaces of said strip-like conductor.
Claim 3
Dependent Claim
15 words
The method as defined in claim 1, wherein said bending steps are performed with dies.
Claim 4
Independent Claim
206 words
A method of shaping a plug receptacle comprising the steps of: a providing a stamped blank (M) comprising a strip-like conductor (1) having longitudinal edges (7), a resilient contact plate (3), and a connective plate (11) extending from an end of the strip-like conductor, the connective plate having a first portion (11a) which is perpendicular to the longitudinal edges of said strip-like conductor and having a second portion (11b) which is parallel to the longitudinal edges, the stamped blank further comprising at least one projection (5,5') extending from a side of said resilient contact plate through an extension (4); a first bending step for bending said extension such that flat surfaces of the at least one projection are perpendicular to flat surfaces of said resilient contact plate; a second bending step, conducted after the first bending step, for bending the first portion of said connective plate such that the flat surfaces of said resilient contact plate are perpendicular to flat surfaces of said strip-like conductor; and a third bending step, conducted after the second bending step, for bending the first portion of said connective plate such that the flat surfaces of the at least one projection are perpendicular to the flat surfaces of the strip-like conductor.
Claim 5
Independent Claim
206 words
A method of shaping a plug receptacle comprising the steps of: a providing a stamped blank (M) comprising a strip-like conductor (1) having longitudinal edges (7), a resilient contact plate (3), and a connective plate (11) extending from an end of the strip-like conductor, the connective plate having a first portion (11a) which is perpendicular to the longitudinal edges of said strip-like conductor and having a second portion (11b) which is parallel to the longitudinal edges, the stamped blank further comprising at least one projection (5,5') extending from a side of said resilient contact plate through an extension (4); a first bending step for bending said extension such that flat surfaces of the at least one projection are perpendicular to flat surfaces of said resilient contact plate; a second bending step, conducted after the first bending step, for bending the first portion of said connective plate such that the flat surfaces of said resilient contact plate are perpendicular to flat surfaces of said strip-like conductor; and a third bending step, conducted after the second bending step, for bending the first portion of said connective plate such that the flat surfaces of the at least one projection are perpendicular to the flat surfaces of the strip-like conductor.
Claim 6
Dependent Claim
24 words
The method as defined in claim 3, wherein the provided stamped blank includes two projection extending from opposite sides of said resilient contact plate.
Claim 7
Dependent Claim
118 words
The method as defined in claim 3, wherein said first bending step comprises the steps of: placing the provided stamped blank on a first lower die (14) having at least one recess (14b) corresponding to the at least one projection, and having a support portion (14a) for supporting the resilient contact plate; and moving a first upper die (13) having at least one convex portion (13a) formed on the surface thereof and corresponding to the at least one recess of the first lower die, such that the at least one convex portion contacts and bends the at least one projection until the surfaces of the at least one projection are perpendicular to the surfaces of said contact plate.
Claim 8
Dependent Claim
84 words
The method as defined in claim 5, wherein said second bending step comprises the steps of: placing the stamped blank on a second lower die (16) having a support portion (16a) for supporting an end portion of said conductor and having a recess (16b); and moving an second upper die (15) having a convex portion (15a) into said recess portion of said second lower die so that the flat surfaces of said resilient contact plate are perpendicular to the flat surfaces of said conductor.
