Abstract: A stacked I/O connector for use with a high speed, high density transceiver that generates a large amount of heat. The connector may be formed with a web-like housing into which leadframe assemblies are inserted. The web-like housing may have openings in the front, back, top and/or sides, enabling airflow through the connector with little resistance. Sidewall openings may open into a channel between the housing and a wall of cage, enabling air flowing to cool transceivers inserted into the cage to pass through the connector assembly with low resistance and high cooling efficiency. A cage for the connector may have openings selectively positioned such that air flowing through the cage to cool transceivers mated to the I/O connector may pass through the connector with low resistance, enhancing cooling efficiency. Such a connector may be used with OSFP transceivers to meet signal integrity and thermal requirements at 112 GBps and beyond.

Abstract: A shield contact system includes a first shield and a second shield. The first shield has a first shield body with a first leading edge and a guiding element extending from the first leading edge along an insertion direction. The second shield has a second shield body defining a receiving space. The second shield body has a second leading edge. The first shield and the second shield are inserted together along the insertion direction to an inserted state in which the guiding element is positioned within the receiving space and the first leading edge is separated from the second leading edge along the insertion direction. The first leading edge does not overlap the second leading edge along the insertion direction in the inserted state.

Abstract: A shield contact system includes a first shield having a first shield body and a protrusion extending from the first shield body, and a second shield having a second shield body and a contact beam extending from the second shield body. The first shield and the second shield are inserted together along an insertion direction from a deflected state to a mated state. The protrusion deflects the contact beam away from the first shield body in the deflected state. The contact beam abuts the first shield body in the mated state.

Abstract: An electrical connector for high speed signals. The connector has multiple conductive elements that may serve as signal or ground conductors. A member formed with lossy material and conductive compliant members may be inserted in the connector. The conductive compliant members may be aligned with conductive elements of the connector configured as ground conductors. For a connector configured to carry differential signals, the ground conductors may separate pairs of signal conductors. The member may further include a conductive web, embedded within the lossy material, that interconnects the conductive compliant members. For a receptacle connector, the conductive elements may have mating contact portions aligned along opposing surfaces of a cavity. The conductive elements may have contact tails for attachment to a printed circuit board and intermediate portions connecting the mating contact portions and the contact tails. The conductive compliant members may press against the intermediate portions.

Abstract: A compact connector operable at data rates up to and beyond 200 Gbps includes a component that presses on high speed signal contact beams to deflect them into a preloaded state. The component may be attached to ground and/or low speed signal contact beams. Those contact beams may be preloaded by engaging their tips to features within the connector. When those contact beams are deflected into a preloaded state, the component presses against the high speed signal contact beams, deflecting them into a preloaded state. Tips on the high speed signal contact beams are not required for preloading and may be shortened relative to a conventional design to reduce stubs on high speed signal paths, which increases operating frequency of the connector. The component may include a conductive portion that connects ground contacts associated with the high speed signal terminals, which improves high frequency performance without additional components.
