Abstract
Abstract A connector with an integral ground plane for making connections between two circuit boards is disclosed in which the connector has a bar-shaped body including generally C-shaped contacts extending in a row on opposite sides of the body. A ground plane in the form of a thin conductive sheet is positioned in the body between the rows, and has a predetermined pattern of projections which are bent to contact specific ones of the C-shaped contacts when the connector is assembled between the two circuit boards.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
A connector having an integral ground plane, comprising: a generally bar-shaped body formed of an insulating material; a sheet of conductive material having a central portion extending along the length of and affixed within the body and having a first plurality of spaced-apart finger-like resilient projections extending from and bent across a first side of the body, where the extension and direction of bend of each of the projections is made in accordance with a predetermined pattern; and a plurality of resilient electrically conductive contacts spaced apart along the length of the body, each contact having a central portion affixed within the body along a plane generally parallel to the central portion of the conductive sheet, and having a first free end extending from and bent across the first side of the body so that when a particular first free end is pressed toward the first side, a portion of that first free end is forced into contact with an adjacent one of the finger-like projections if that adjacent projection is bent toward the particular first free end.
Claim 2
Dependent Claim
178 words
A connector having an integral ground plane, comprising: a generally bar-shaped body formed of an insulating material; a sheet of conductive material having a central portion extending along the length of and affixed within the body and having a first plurality of spaced-apart finger-like resilient projections extending from and bent across a first side of the body, where the extension and direction of bend of each of the projections is made in accordance with a predetermined pattern; and a plurality of resilient electrically conductive contacts spaced apart along the length of the body, each contact having a central portion affixed within the body along a plane generally parallel to the central portion of the conductive sheet, and having a first free end extending from and bent across the first side of the body so that when a particular first free end is pressed toward the first side, a portion of that first free end is forced into contact with an adjacent one of the finger-like projections if that adjacent projection is bent toward the particular first free end.
Claim 3
Dependent Claim
133 words
The connector of claim 1 in which the sheet of conductive material includes a second plurality of spaced-apart finger-like resilient projections extending from and bent across a second side of the body opposite the first side, where the extension and direction of bend of each of the second plurality of projections is made in accordance with the predetermined pattern; and in which each of the plurality of resilient contacts includes a second free end extending from and bent across the second side of the body so that when a particular second free end is pressed toward the second side, a portion of that second free end is forced into contact with an adjacent one of the second plurality of finger-like projections if that adjacent projection is bent toward that particular second free end.
Claim 4
Dependent Claim
218 words
A connector having an integral ground plane, comprising: a generally bar-shaped body formed of an insulating material; a sheet of conductive material having a central portion extending along the length of and affixed within the body and having first and second pluralities of spaced-apart finger-like resilient projections extending through the body from opposite sides of the central portion and bent across first and second opposing sides, respectively, of the body, where the extension and direction of bend of each of the projections is made in accordance with a predetermined pattern; and a plurality of resilient electrically conductive contacts spaced apart in two rows along the length of the body, the rows being generally parallel to and on opposing sides of the central portion of the conductive sheet, each contact having a central portion affixed within the body and first and second free ends extending from the first and second sides, respectively, of the body, where each free end is bent across the respective side of the body in a direction toward the sheet of conductive material so that when a particualr free end is pressed toward its respective side, a portion of that free end is forced into contact with an adjacent one of the finger-like projections if that adjacent projection is bent toward the particular free end.
Claim 5
Dependent Claim
218 words
A connector having an integral ground plane, comprising: a generally bar-shaped body formed of an insulating material; a sheet of conductive material having a central portion extending along the length of and affixed within the body and having first and second pluralities of spaced-apart finger-like resilient projections extending through the body from opposite sides of the central portion and bent across first and second opposing sides, respectively, of the body, where the extension and direction of bend of each of the projections is made in accordance with a predetermined pattern; and a plurality of resilient electrically conductive contacts spaced apart in two rows along the length of the body, the rows being generally parallel to and on opposing sides of the central portion of the conductive sheet, each contact having a central portion affixed within the body and first and second free ends extending from the first and second sides, respectively, of the body, where each free end is bent across the respective side of the body in a direction toward the sheet of conductive material so that when a particualr free end is pressed toward its respective side, a portion of that free end is forced into contact with an adjacent one of the finger-like projections if that adjacent projection is bent toward the particular free end.
Claim 6
Independent Claim
225 words
A method of making a connector having an integral ground plane, comprising: providing a plurality of resilient electrical contacts each having a central portion and first and second free ends; providing first and second halves of a generally bar-shaped body, each half formed of an insulating material and where the contacts have their central portion embedded in at least one half of the body to form a row of spaced apart contacts; providing a sheet of conductive materials; forming the sheet to have spaced-apart finger-like projections extending from at least one end of a central portion, where the spacing of the projections corresponds to the spacing of the contacts; reducing the length of particular ones of the projections in accordance with a predetermined ground plane pattern; bending the projection approximately perpendicular to the central portion of the sheet, where the direction of bend of each projection is made in accordance with the predetermined pattern; fastening the first and second halves on opposite sides of the central portion of the sheet; and bending the free ends of the contacts toward the central portion of the sheet, whereby when a particular free end is pressed toward the body, a portion of that free end is forced into contact with an adjacent one of the finger-like projections if that adjacent projection is bent toward the particular free end.
