Abstract
Abstract A matched impedance printed circuit board connector comprising a housing mounted on a mounting board having a ground plane and signal traces separated by an insulator. A grounding bus extends lengthwise in the housing below the printed circuit board receiving slot therein. Signal contacts in the housing are mounted in plated through holes in the mounting board which are connected to the signal traces. The grounding bus has mounting portions which are mounted in other plated through holes in the board which are joined to the ground plane. Ground contacts are also provided in the housing which are mounted in additional plated through holes which are also joined to the ground plane so that the ground contacts and grounding bus are electrically interconnected. Preferably two such ground contacts are positioned on opposite sides of the signal contacts.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
An electrical edge connector for a printed circuit board comprising: a mounting board having a ground plane and a signal trace separated by an insulator, a plurality of plated through holes in said board, a first plated through hole being connected to said trace, and second and third plated through holes being connected to said ground plane; an elongated insulative connector housing mounted on said board having a slot therein for receiving the edge of a printed circuit board; electrical contacts in said housing for engaging said printed circuit board edge; a grounding bus extending lengthwise in said housing below said slot; a first contact having a mounting portion mounted in said first plated through hole; and a second contact and said grounding bus having mounting portions mounted in said second and third plated through holes, respectively.
Claim 2
Dependent Claim
137 words
An electrical edge connector for a printed circuit board comprising: a mounting board having a ground plane and a signal trace separated by an insulator, a plurality of plated through holes in said board, a first plated through hole being connected to said trace, and second and third plated through holes being connected to said ground plane; an elongated insulative connector housing mounted on said board having a slot therein for receiving the edge of a printed circuit board; electrical contacts in said housing for engaging said printed circuit board edge; a grounding bus extending lengthwise in said housing below said slot; a first contact having a mounting portion mounted in said first plated through hole; and a second contact and said grounding bus having mounting portions mounted in said second and third plated through holes, respectively.
Claim 3
Dependent Claim
28 words
A connector as set forth in claim 1 wherein: said mounting portions of said contacts and said grounding bus have an interference fit with said plated through holes.
Claim 4
Dependent Claim
53 words
