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.

Connector configurable for high performance

A spring seal for a cage of a high speed I/O connector, such as those compliant with an OSFP standard. The spring seal suppresses resonances in the operating frequency range of the connector in a space between the cage and a transceiver inserted in a channel of the cage to mate with the I/O connector. The spring seal has multiple peaks, separated by valleys, with short conducting paths between the peaks and valleys. The spring seal may connect a conductive exterior of the transceiver to a wall of the cage, with the peaks contacting a conductive exterior of the transceiver and the valleys contacting walls of the cage. The spring seal may have a plurality of slits that reduce the spring force while providing conducting paths between peaks and valleys.

I/O connector cage with high shielding effectiveness

A modular electrical connector with broad-side coupled signal conductors in a right angle intermediate portion. Broadside coupling provides balanced pairs for very high frequency operation. The connector is assembled with multiple subassemblies, each of which has multiple pairs of signal conductors. The subassemblies are formed from an insulative portion having grooves in opposite sides into which the intermediate portions of signal conductors. Covers, holding the signal conductors in the grooves, establish the position of the signal conductors relative to reference conductors at the exterior of subassembly, so as to provide a controlled impedance. Lossy material is positioned between the pairs in a subassembly and/or contacts the reference conductors of the subassemblies, and the lossy material of the subassemblies is in turn connected with a conductive structure.

Very high speed, high density electrical interconnection system with broadside subassemblies

A cable connector with improved performance and ease of use. The connector has staggered ports to reduce crosstalk and to prevent incorrect insertion of a plug into a receptacle. The plug may be constructed with subassemblies, each of which has a lossy central portion. Conductive members embedded within an insulative housing of the subassemblies may be used to electrically connect ground conductors within the subassemblies. Further, the connector may have a quick connect locking screw that can be engaged by pressing on the screw, but requires rotation of the screw to remove. Additionally, a ferrule may be used in making a mechanical connection between a cable bundle and a plug and making an electrical connection between a braid of the cable bundle and a conductive shell of the plug. The ferrule may be in multiple pieces for easy attachment while precluding deformation of the cable, which disrupts electrical performance.

Plug

A modular electrical connector with broad-side coupled signal conductors in a right angle intermediate portion and edge coupled end portions. Broadside coupling provides balanced pairs for very high frequency operation, while edge coupling provides a high density interconnection system at low cost. Each module has separately shielded signal conductor pairs. The shielding is shaped to avoid or suppress undesirable propagation modes within an enclosure formed by shielding per module. Lossy material is selectively placed within and outside the shielding per module to likewise avoid or suppress unwanted signal propagation.

Very high speed, high density electrical interconnection system with edge to broadside transition

An electrical connector for connecting a conductor of a daughter card connector wafer with a blade in the housing of a backplane connector. The daughter card conductor has a body with two elongated beams extending outward from the body. The two elongated beams each have an outer edge and an inner edge, whereby an opening is defined between the inner edges. The backplane conductor has a body with a narrowed tab portion extending outward from said second conductor body. The narrowed tab portion having outer opposite edges and is sized so that the narrowed tab portion fits between at least a portion of the outer edges of the two elongated beams, and in some cases between at least a portion of the inner edges of the two elongated beams.
