Abstract: An I/O connector assembly configured for making a cabled connection to an interior portion of a printed circuit board for at least some signals passing through the I/O connector. The I/O connector assembly may be assembled by mounting a cage to a printed circuit board. A receptacle connector, including cables extending from a rear of the connector, may be inserted through an opening in the top or rear of the cage. The receptacle connector may be positioned in the cage by at least one retention member on the cage. A plug, mating to the receptacle connector, also may be positioned by a retention member on the cage. Positioning both the plug and receptacle relative to the cage reduces the tolerance stackup of the assembly and enables the connectors to be designed with shorter wipe length, which enables higher frequency operation.

Abstract: High speed waveguide-based data communication systems are disclosed. Such systems may include separable electrical connectors, forming signal propagation paths between electronic assemblies with one or more waveguides.

Abstract: An electrical interconnection system with an adapter mounted in an opening within a connector interface of a panel of an electronic enclosure is described. A sealing member may be used to prevent passage of foreign matter, such as liquid, gas or dust particles into the enclosure and into the mating region between the adapter and a mating plug connector. The sealing member may comprise a base and a sidewall configured to wrap around an outer border of the adapter. The sealing member may be configured to form a first sealing interface with the panel, and a second sealing interface with the plug connector. The first and second sealing interfaces may be orthogonal to each other. The sealing member may be made of an elastic material.

Abstract: In various embodiments, compact connector designs may be provided that have reduced board pitch (e.g., 1.80 mm, 1.50 mm, 1.27 mm, etc.), but are still capable of accommodating large electrical conductors (e.g., 1.4 mm, 1.1 mm, 0.9 mm, etc.). In this manner, PCB footprint may be reduced (e.g., by 50% when a staggered connector configuration is used), while adequate current carrying capacity may be maintained (e.g., 2 A, 3 A, 4 A, etc.). Additionally, or alternatively, one or more other advantages may be achieved, such as ruggedness (e.g., vibration endurance), error proofing, configuration flexibility, ease of manufacturing, ease of assembly, and/or lowered costs.

Abstract: To support a large current, a circuit board may be a hybrid card, with a signal portion formed using a conventional PCB manufacturing techniques and a power portion formed with one or more blades mechanically coupled to the signal portion. The blade (s) may be metal plates. The hybrid card may be usable with a hybrid edge connector that includes an insulative housing with a slot lined with signal terminals, in a signal portion, and power terminals in a power portion. The power terminals may be made with multiple layers, with each layer formed into one or more fingers. Each finger may be configured to make contact with an edge of a blade inserted in the slot such that each terminal has multiple contact points to the blade and can carry a large current. The slot in the connector housing may have different widths in the signal and power portions and the center lines of those portions may be offset with respect to each other.

Abstract: A power terminal includes first and second conductive sheets. The first conductive sheet includes a first joining portion, first fingers extending from the first joining portion, and a first mounting portion extending from the first joining portion and configured to mount to a substrate. The first fingers have hooked ends connected to the first joining portion by first beams. The second conductive sheet includes a second joining portion, second fingers extending from the second joining portion, and a second mounting portion extending from the second joining portion and configured to mount to the substrate. The two second fingers have curved ends connected to the second joining portion by second beams. The hooked ends and the curved ends include contact surfaces configured to contact a same side of a card. At least one of the first and second mounting portions includes at least two mounting tails.

Abstract: A connector that enables electronic assemblies to be efficiently configured for any of multiple power requirements. The connector may have a mating interface, which may mate with a power supply, a mounting interface for attaching the connector to a PCB and a power tap off interface. The power tap off interface may enable distribution of a portion of the power received through the mating interface to remote locations on the PCB. The connector may be assembled with conductive element subassemblies, enabling efficient configuration of the connector with conductive elements with and without mating contact portion for power tap off. Each subassembly may include a member to which other members with mating contact portions and/or tails for a mounting interface are attached.

Abstract: Embodiments disclosed herein relate to a high frequency connector system with reduced stub lengths that provide improved performance at high frequencies. A first connector includes a plurality of mating contacts designed to electrically connect to a second plurality of mating contacts associated with a second connector. The first connector includes one or more elastic members such that when the second connector is mated to the first connector, the one or more elastic members are compressed between the first and second connectors. The first and second plurality of contacts overlap by a first distance when initially mated, but when the connectors are released, the first elastic member biases the second connector away from the first connector such that the first and second plurality of contacts overlap by a second distance smaller than the first distance.

Abstract: Electrical connectors for very high speed signals, including signals at or above 112 Gbps. Effectiveness of shielding along the signal paths through the mating electrical connectors may be enhanced through the use of one or more techniques, including enabling two-sided shielding, connections between shield members and between shield members and grounded structures of printed circuit boards to which the connectors are mounted, and selective positioning of lossy material. Such techniques may be simply and reliably implemented in high density connector using one or more techniques. An electrical connector may include core members held by a housing together with leadframe assemblies attached to the core members. The core members may include features that would be difficult to mold in a housing and may include both shields and lossy materials in locations that would be difficult to incorporate in a leadframe assembly.

Abstract: Electrical connectors for very high speed signals at frequencies to support high data rates, including at or above 112 Gbps. A connector includes lead assemblies, each of which includes conductors held by an assembly housing, and shielding members disposed on opposite sides of the assembly housing. Each conductor has a mating end and a mounting end opposite the mating end. The shielding members have tabs disposed on the mating ends of ground conductors from the opposite sides. The tabs on the opposite sides can be welded to respective ground conductors simultaneously. The tabs are connected to bodies of respective shielding members by beams separated by slots. The slots are sized to both provide tolerances for welding and to reduce crosstalk further. The shielding members alternatively or additionally can have tabs disposed on the mounting ends of the ground conductors from the opposite sides.
