Abstract
Abstract Three electrically conductive sheets are provided which are bonded together to form an electrical coaxial interface connector. The middle or signal plane sheet is made of a spring material and has formed therein a plurality of paired contact members. The outer or ground plane sheets are coated with a dielectric material. These outer sheets have openings therein which are indexed with the underlying contact element of the paired contact members. Once the three conductive sheets are bonded together, the interconnecting pads between the paired contact members are removed to provide electrical isolation. A tool is provided which consists of pins and opposed die surfaces which, when positioned with respect to the connector, provides a means by which the contact elements are bent so that they extend through the openings indexed therewith in the outer conductive sheets.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
148 words
An electrical interconnecting means between circuits on circuit boards or the like, comprising: a first, second and third electrically conductive sheet, the second sheet being made of a spring metal forming the inner laminae signal sheet bonded between the first and third sheets, the first and third sheets being coated with a dielectric material and forming the ground signal sheets; paired electrical contact members formed in said middle sheet; a precious metal coating formed at least on said contact elements of said paired contact members; said ground sheets having openings indexed with one of the contact elements in each pair of contact members; means for selectively disconnecting the paired contact members from the other paired contact members on the sheet; and means for bending the contact elements so that they extend thru the openings indexed therewith so that interconnection between circuits on adjacent circuit boards can be made.
Claim 2
Dependent Claim
148 words
An electrical interconnecting means between circuits on circuit boards or the like, comprising: a first, second and third electrically conductive sheet, the second sheet being made of a spring metal forming the inner laminae signal sheet bonded between the first and third sheets, the first and third sheets being coated with a dielectric material and forming the ground signal sheets; paired electrical contact members formed in said middle sheet; a precious metal coating formed at least on said contact elements of said paired contact members; said ground sheets having openings indexed with one of the contact elements in each pair of contact members; means for selectively disconnecting the paired contact members from the other paired contact members on the sheet; and means for bending the contact elements so that they extend thru the openings indexed therewith so that interconnection between circuits on adjacent circuit boards can be made.
Claim 3
Dependent Claim
48 words
An electrical interconnecting means according to claim 1, wherein said paired electrical contact members are S-shaped the upper and lower hook of the S forming said pair of contact elements and the middle portion of the S forming a base about which the pair of contact elements bend.
Claim 4
Dependent Claim
37 words
An electrical interconnecting means according to claim 2, wherein said paired electrical contact members formed in said signal sheet are held together by interconnecting pads at the remote corners of the S-shaped pairs of electrical contact members.
Claim 5
Dependent Claim
27 words
An electrical interconnecting means according to claim 3, wherein said first and second electrically conductive ground plane sheets each have pad openings indexed with the interconnecting pads.
Claim 6
Dependent Claim
32 words
An electrical interconnector according to claim 4, wherein said pad openings are extensions of the openings in the ground plane sheets indexed with the contact elements of the paired electrical contact members.
Claim 7
Dependent Claim
43 words
An electrical interconnecting means according to claim 5, wherein said means for selectively disconnecting the paired contact members from the other paired contact members in the sheet comprises removing selected interconnecting pads through the pad openings in the ground signal sheets by etching.
Claim 8
Dependent Claim
70 words
An electrical interconnecting means according to claim 6, wherein further openings are provided in each ground signal sheet each uncovering a portion of the back of a contact element of an S-shaped paired contact member which is indexed with one of said openings in the opposite ground signal sheet so that said contact element can be bent to extend through said opening indexed therewith by pushing through said further opening.
Claim 9
Dependent Claim
73 words
An electrical interconnecting means according to claim 7, wherein said further openings are each a further extension of said opening indexed with a contact element and uncovering the back of a portion of a contact element of a paired electrical contact member which is located diagonally upward away from the free end of a top contact and diagonally downward away from the free end of a bottom contact of an S-shaped contact member.
Claim 10
Dependent Claim
93 words
An electrical interconnecting means according to claim 8, wherein said means for bending the contact elements so that they extend through the openings indexed therewith comprises a tool having die cavities placed adjacent to said openings through which Said contact elements are to extend, and a plurality of pins arranged on the other side of said interconnector indexed with said further openings and applying a pushing force to the underlying portion of the back of a contact element to cause it to bend through said opening indexed therewith and into said die cavity.
