Abstract: PROBLEM TO BE SOLVED: To provide a card edge connector capable of being manufactured at low cost, which is strong, having high reliability, having high circuit density, and capable of sufficiently functioning in a high-speed digital circuit. SOLUTION: This card edge connector 12, mounted on a circuit board and for detachably receiving a circuit card, is provided with a long thin housing 26 for forming a card receiving slot 34. Many terminal receiving cavities intersect the slot 34 and extend to both sides. Alternate cavities house a reference terminal and a signal terminal 62, and all terminals are provided with downwardly extending circuit board contacts 72, 92 and upward extending spring arms. There are many similar terminal sets 104, each terminal set is provided with one reference terminal and a pair of facing signal terminals 62 parallel to the reference terminal and overlapped to it. The upward extending spring arm of the reference terminal includes an oversize wide section, the connection between the reference terminal and the signal terminals 62 is strengthened, so that, signal leakage is reduced.

Abstract: PROBLEM TO BE SOLVED: To reduce crosstalk by positioning an elastic arm of a second terminal within the cross section of an elastic arm of a first terminal in the length direction of a dielectric housing when a circuit board is inserted into a card slot and the elastic spring arms of the first and second terminals are deformed. SOLUTION: An elastic spring arm 40c of a signal terminal is positioned within the cross section in the length direction of an elastic spring arm 38c of an earthed terminal, parallel to the elastic spring arm 38c and slightly narrow. A finger part 40e is positioned within the cross section in the length direction of an enlarged head 38e, and an enlarged supporting part 40g is positioned within the cross section in the length direction of a shield 38g. The shape in the whole construction of a signal terminal 40 is positioned within the cross section in the length direction of the earthed terminal 38, the earthed terminal 38 is positioned in the shadow of the signal terminal 40 or laid down on the signal terminal 40. Therefore, good signal/capacitive coupling is formed between both terminals, bonding between signals is decreased, and crosstalk of a connector is substantially decreased.

Abstract: A CARD EDGE CONNECTOR (12) FOR MOUNTING ON A CIRCUIT BOARD (10) AND REMOVEABLY RECEIVING A CIRCUIT CARD (16) INCLUDES AN ELONGATED HOUSING (26) DEFINING A CARD RECEIVING SLOT (34). NUMEROUS TERMINAL RECEIVING CAVITIES INTERSECT AND EXTEND TO BOTH SIDES OF THE SLOT (34). ALTERNATE CAVITIES (44, 46) INCLUDE STAMPED REFERENCE (GROUND OR POWER) TERMINALS (60) AND SIGNAL TERMINALS (62), ALL HAVING DOWNWARDLY EXTENDING BOARD CONTACTS (72, 92) AND UPWARDLY EXTENDING SPRING ARMS (74, 94). THERE ARE NUMEROUS SIMILAR SETS OF FACE TO FACE CONTACTS, EACH INCLUDING A REFERENCE CONTACT (72) PARALLEL TO AND SUBSTANTIALLY OVERLYING AN OPPOSED PAIR OF SIGNAL CONTACTS (92). THE UPWARDLY EXTENDING REFERENCE TERMINAL SPRING ARMS INCLUDE OVERSIZE PAD PORTIONS (80) FOR REDUCING CROSSTALK BY INCREASING COUPLING BETWEEN THE REFERENCE AND SIGNAL TERMINALS (60, 62). THE CIRCUIT PATHS TO THE CIRCUIT BOARD (10) ARE IN AN ARRAY SYMMETRICAL ABOUT THE CENTERLINE (108) OF THE CIRCUIT CARD (16), WITH PARALLEL INNER LINES (110, 112) OF CIRCUITS CONTAINING ONLY REFERENCE CONTACTS (72) AND OUTER LINES (114, 116) OF CIRCUITS CONTAINING ONLY SIGNAL CONTACTS (92).FIGURE 4
