Abstract
Abstract A high performance card edge connector (10) includes a housing (16) with an elongated printed circuit card receiving slot (38) in a top wall (18). Terminals (44,46,48) are mounted in transverse cavities (28) intersected by the slot. Alternate cavity portions (28A) receive a pair of signal terminals (44,46) and interspersed alternate cavity portions (28B) receive single ground terminals (48). Each terminal includes a downwardly extending board contact portion (52,64,74) for connection to a printed circuit board and a card contact portion (56,68,80) in the slot for engagement with a contact pad of an inserted card. Each signal terminal pair may be flanked by two ground terminals on the same side of the slot and may be transversely opposite a ground terminal on the opposite side of the slot. A uniform identical cavity configuration permits each cavity portion to receive either a ground terminal or a pair of signal terminals.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
211 words
A card edge connector (10) for a removable printed circuit card (14) having a mating edge (36) with a plurality of conductive pads (86,88,90), said connector comprising: an insulating housing (16) including elongated top (18) and bottom walls and elongated spaced apart side walls (22,24); a plurality of transverse cavities (28) extending between said side walls; an elongated slot (38) in said top wall for receiving the mating edge of the circuit card, said slot intersecting said cavities and dividing said cavities into similar, aligned cavity portions (28A,28B) at opposite sides of said slot; and a plurality of ground and signal terminals (44,46,48) received in said cavity portions, each of said terminals including a mounting portion (60,70,82) for holding said terminal in one of said cavity portions and a contact portion (56,68,80) for engaging one of the contact pads upon insertion of the mating edge into said slot; the card edge connector being characterized by: a single one of said ground terminals (48) being disposed in each of a group of spaced apart first cavity portions (28B), and a plurality of said signal terminals (44,46) being disposed in each of a group of second cavity portions (28A), each of said second cavity portions being adjacent one of said first cavity portions.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
27 words
A card edge connector as claimed in claim 1 wherein said two of said second cavity portions are disposed between each pair of said first cavity portions.
Claim 4
Dependent Claim
22 words
A card edge connector as claimed in claim 1 wherein each of said second cavity portions contains first and second signal terminals.
Claim 5
Dependent Claim

Claim 8
Dependent Claim
34 words
A card edge connector as claimed in claim 7, said contact portions of said ground terminals being spaced farther from said bottom wall than said contact portions of said first and second signal terminals.
Claim 9
Dependent Claim
41 words
A card edge connector as claimed in claim 1 wherein each of said first alternate cavity portions on one side of said slot is directly opposed to one of said second alternate cavity portions on the opposite side of said slot.
Claim 10
Dependent Claim
58 words
A card edge connector as claimed in claim 9 wherein each of said second cavity portions contains first and second signal terminals having vertically aligned and spaced apart contact portions and each of said first cavity portions contains a ground terminal having a contact portion longitudinally offset between the contact portions of adjacent first and second signal terminals.
Claim 11
Dependent Claim
84 words
A card edge connector as claimed in claim 9 wherein the contact portions of said first signal terminals are in a first row parallel to said bottom wall, the contact portions of said second signal terminals are in a second row parallel to said first row and farther from said bottom wall than said first row, and the contact portions of said ground terminals are in a third row parallel to said second row and farther from said bottom wall than said second row.
