摘要： A high-speed plug-in card connector comprising two terminal assemblies with reversely arranged internal structure and a housing. Each terminal assembly includes a metal sheet, a conductive plastic, and an injection-molded terminal strip. The conductive plastic is formed on the side of the metal sheet by injection molding and connects the metal sheet with a ground terminal of the terminal strip. The conductive plastics of the two terminal assemblies are located in the very middle of the connector. The conductive plastics fix the two terminal assemblies together with a snap-in connection. The housing is clamped at the end on the side where the two terminal assemblies are snapped together.

摘要： A fine pitch high density high-speed orthogonal card edge connector includes at least one signal transmission assembly which includes a plug-in connector, a press-fit connector, and a PCB board. A side of the PCB board is provided with a row of first pads, and a side of the PCB board adjacent to the side where the first pads are located is provided with a row of second pads. Each first pad corresponds to one second pad one by one through the wiring of the PCB board. An extension line of each first pad is perpendicular to an extension line of each second pad. The plug-in connector is mounted on the side of the PCB board provided with the first pads and is connected to the first pads.

摘要： A connector for use with high-speed signals. The connector includes a connector subassembly that includes conductive elements held in a row by an insulative member. Each conductive element includes a mating end, a mounting end opposite the mating end, and an intermediate portion extending therebetween. The conductive elements include ground conductors dispersed between pairs of signal conductors. The ground conductors are wider than the signal conductors at the intermediate portions, and have same widths as the signal conductors at the ends. For each ground conductor, the intermediate portion has first and second portions separated by a slot until joining each other at the mating end. The insulative member holds the conductive elements at least partially through the slots of the ground conductors. Such a configuration meets signal integrity requirements in connectors designed for 64 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.

摘要： A connector for use with high-speed signals. The connector includes a connector subassembly having conductors disposed in groups and a shielding shell at least partially encircling each group. Each conductor includes a mating end and a mounting end opposite the mating end. The shielding shell includes openings that expose contact surfaces of the conductors at the ends. The shielding shell is formed by attaching a second shell part to a first shell part. The first shell part has plateaus and valleys, and the second shell part is attached to the first shell part at the valleys, such that tubular structures are formed. The shielding shell includes contact surfaces disposed on the same planes with the contact surfaces of the conductors at the ends, respectively. Such a configuration meets signal integrity requirements in connectors designed for 64 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.

摘要： A connector for use with high-speed signals. The connector may include a row of conductive elements comprising signal conductors and ground conductors. A signal conductor may include a mating end, a mounting end opposite the mating end, and an intermediate portion extending therebetween. A ground conductor may include a shell at least partially encircling intermediate portions of a group of signal conductors, with openings that expose contact surfaces of the signal conductors at the ends. The ground conductors may include contact members aligned with the mating contact surfaces of the signal conductors. Each shell may be coupled to a ground mounting location on each side of a respective group of signal conductors, with adjacent shells sharing a ground mounting location. Such a configuration may meet signal integrity requirements in connectors designed for 64 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.

摘要： A connector for use with high-speed signals. The connector has a housing, which includes conductive elements held in a row by a housing. Each conductive element includes a thinner portion and a thicker portion. The conductive elements are configured to make contact with a mating component at the thicker portions. The thinner portions are closer to mating ends of respective conductive elements than respective thicker portions. The housing is configured to provide voids selectively disposed underneath the conductive elements. Such a configuration increases impedances for the conductive elements at locations that would otherwise have lower impedance and therefore reduces impedance variations along signal transmission paths. Such a configuration can also reduce stub size and therefore reduce insertion loss. Such a configuration meets signal integrity requirements in connectors designed for 64 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.

摘要： A connector for use with high-speed signals. The connector includes conductive elements held in a row by an insulative member, a shielding member stacked on the insulative member, and a lossy member stacked on the shielding member and electrically connecting the shielding member to selected ones of the conductive elements. Each conductive element includes a mating end and a mounting end opposite the mating end. The insulative member includes first and second edges extending parallel to the row. The first edge and second edge are closer to the mating ends and mounting ends of the conductive elements, respectively. The shielding member includes a portion projecting from the first edge to provide shielding to the conductive elements beyond the first edge of the insulative member. Such a configuration meets signal integrity requirements in connectors designed for 64 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.

摘要： A connector for use with high-speed signals. The connector includes conductors held in a housing having a slot for receiving a mating component. Each conductor has a mating end curving into the slot and a mounting end extending out of the housing. The connector has a conductive shell at least partially enclosing the housing. The conductive shell covers one or more sides of the slot and substantially overlaps the mounting ends viewing from a top of the mounting interface to provide shielding to the mating and mounting interfaces. The conductive shell is coupled to ground through ground conductors of the connector. The connector has a lossy member disposed adjacent the mounting interface and coupled to the ground conductors. Such a configuration meets signal integrity requirements in connectors designed for 32 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.
