An electrical connector includes a housing having a first end and a second end with a mating slot formed between the first and second ends configured to receive a mating connector having contact pads. A leadframe assembly is disposed in the housing. The leadframe assembly has a contact array including ground contacts and signal contacts interspersed between corresponding ground contacts. The leadframe assembly has an overmold body supporting the ground and signal contacts. The overmold body has lossy ground absorbers coupled to corresponding ground contacts. The lossy ground absorbers are manufactured from lossy material absorbing electrical resonance propagating through the leadframe assembly.

A connector includes a connector body, a plurality of wafers arranged within the connector body, and a weld tab defined by a unitary member that includes a plurality of weld tab legs and a plurality of weld tab arms. The plurality of weld tab arms are arranged to engage with corresponding weld tab arm holes included in the connector body, and the plurality of weld tab legs are arranged to engage with a circuit board when the connector is mounted to the circuit board. The weld tab prevents the plurality of wafers from withdrawing from the connector body when the plurality of weld tab arms are engaged with the corresponding weld tab arm holes.

An electrical connector with reduced cross talk and controlled impedance. The connector comprises hybrid shields with lossy portions and conductive portions. The synergistic effect of the lossy portions and the conductive portions allows the hybrid shields to be relatively thin such that they can be incorporated into the mating interface regions or other mechanically constrained regions of the connector to provide adequate crosstalk suppression without undesirably impacting impedance. The conductive portions may be shaped to preferentially position the conductive regions adjacent signal conductors susceptible to cross talk to further contribute to the synergy. The conductive regions may include holes to contribute to desired electrical properties for the connector.

A system, according to one embodiment, includes a first end having several first contacts configured for coupling with a circuit board, a second end oriented about orthogonal to the first end, and a plurality of leads connecting the first and second contacts. The second end has a plurality of second contacts configured for coupling directly with a card edge of an electronic device. The orientation of the second end relative to the first end is fixed. A system, according to another embodiment, includes a circuit board, a plurality of such connectors.

In accordance with the various embodiments disclosed herein, electrical connector footprints, such as printed circuit boards, is described comprising one or more of signal traces that each include a first section that extends parallel to the linear array direction and a second section extends in a direction that is different than the linear array direction.

A card connector corresponding to a first card type associated with a plurality of electrical contacts for receiving cards corresponding to various card types, each card type associated with a set of electrical contacts fewer than, more than or the same number of electrical contacts as the first card type. An elongated body may be formed with a closed end and an open end. A cap may be positioned on the open end to configure the card connector in a closed configuration to support cards of a card type associated with fewer or the same number of electrical contacts. The cap may be removed to configure the card connector in an open configuration to support cards associated with more electrical contacts. The cap may have PCB connectors for positioning the cap a distance from the elongated body to configure the card connector in an augmented open configuration.

A card edge connector mounted on a circuit board includes an insulating housing having two side walls extending along a longitudinal direction, plural terminals retained in the insulating housing, at least one nut fixed in the insulating housing adjacent to the side walls, and a bolt matching the nut to bolt the card edge connector to the circuit board.

A connection system comprises a printed circuit board. The printed circuit board comprises a top face and a bottom face. The printed circuit board also comprises a first edge that is normal to the top face and bottom face. The printed circuit board also comprises a second edge that is normal to the top face and bottom face. The first edge face and second edge face intersect at an angle that is not a straight angle. The connection system also comprises a coplanar card-edge socket on the printed circuit board. The socket comprises a top section that interfaces with the top face of the printed circuit board along the first and second edge faces of the printed circuit board. The socked also comprises a bottom section that interfaces with the bottom face of the printed circuit board along the first and second edge faces of the printed circuit board.

A connector that is mounted on an external mount substrate and in or from which an external pluggable substrate is inserted or extracted in an insertion-extraction direction Die includes: pin groups each including a plurality of aligned contact pins; an outer housing holding the pin groups and a frame attached to the outer housing. The outer housing has a main body and a protruding part which protrudes in the insertion-extraction direction Die from the main body and in which a slot opening in or from which the pluggable substrate is inserted or extracted is formed. The frame surrounds the whole circumference of the protruding part and is installed on an installation surface of the main body substantially orthogonal to the insertion-extraction direction Die.
