Abstract
Abstract A stamped contact is disclosed having an integral closed crimp barrel suitable for military/aerospace applications. In one embodiment, the crimp barrel has a rectangular cross section. A method is disclosed for making the contact in which the contact is stamped from a sheet having a relatively thick marginal edge which provides the rectangular crimp barrel for the contact. The bore in the barrel is drilled after the stamping operation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
110 words
A method of making an electrical contact comprising the steps of: providing a sheet of metal having a marginal area along one edge thereof of a thickness greater than the thickness of the remainder of said sheet; stamping a contact body from said sheet with the longitudinal axis of said body perpendicular to said edge whereby said marginal area provides at one end of said contact body a solid barrel portion of rectangular cross-section and said remainder of said sheet provides at the other end of said contact body a substantially flat portion; and forming an axial bore in said solid barrel portion to form an integral closed crimp barrel.
Claim 2
Independent Claim
110 words
A method of making an electrical contact comprising the steps of: providing a sheet of metal having a marginal area along one edge thereof of a thickness greater than the thickness of the remainder of said sheet; stamping a contact body from said sheet with the longitudinal axis of said body perpendicular to said edge whereby said marginal area provides at one end of said contact body a solid barrel portion of rectangular cross-section and said remainder of said sheet provides at the other end of said contact body a substantially flat portion; and forming an axial bore in said solid barrel portion to form an integral closed crimp barrel.
Claim 3
Dependent Claim
26 words
A method as set forth in claim 1 wherein: said bore is formed with its center axis substantially in the plane of said flat forward portion.
Claim 4
Dependent Claim
13 words
An electrical contact which has been made by the method of claim 1.
Claim 5
Dependent Claim
32 words
A method as set forth in claim 1 wherein: said bore is formed with its center axis in a plane parallel to but spaced from the plane of said flat forward portion.
Claim 6
Dependent Claim
41 words
A method as set forth in claim 4 wherein: said bore is formed to extend from the front to the rear of said barrel portion; and said flat forward portion is formed to provide a shoulder in front of said bore.
Claim 7
Dependent Claim
20 words
A method as set forth in claim 1 wherein: said substantially flat portion is formed into a substantially cylindrical configuration.
Claim 8
Dependent Claim
20 words
A method as set forth in claim 6 wherein: said barrel portion is formed to provide a substantially circular cross-section.
