Abstract: Card edge connectors that are reliable and robust against impacts by external forces while having narrower widths by industry standards. A connector includes a housing having a body with a slot elongated longitudinally. The housing has a pair of towers extending vertically from opposite ends of the longitudinal slot. Each tower has a slot elongated vertically, and is narrower than the body in a transverse direction. The longitudinal slot and the vertical slots are configured to receive edges of an electronic card. The connector has a pair of reinforcing members. Each reinforcing member is at least partially disposed on a tower and configured to support a joint between the tower and the body of the housing. Such a configuration can increase robustness of the connector at the joints and therefore reduce the risks of deforming or cracking the towers when the connector is impacted by an external force.

Abstract: High-density, high-speed electrical connectors and system thereof are provided. A connector can include a corrugated shield. The shield includes first portions forming recesses where one or more signal terminals can be disposed, and second portions connecting adjacent first portions. The second portions include beams configured for contacting complementary beams of a mating connector. Both the signal terminals and the beams of the shield are configured for two contact points. The shields are configured such that the shields of two mating connectors form enclosures around the mating contact portions (e.g., both of the two contact points). Power conductors, including power terminals and one or more pairs of power pin and power receptacle, can be symmetrically disposed. This configuration allows connectors with identical mating interfaces to reliably mate with each other, thereby enabling simplified and flexible system architecture while supporting high-speed operation, such as data rates of 224 Gbps and beyond.

The connector comprises a housing having a slot elongated in a longitudinal direction and a pair of towers disposed on opposite ends of the housing and extending in a vertical direction. A pair of latches are disposed in the towers, respectively. Each latch has a groove disposed above the respective tower for receiving a flange of a card inserted in the slot. Each latch has a clip disposed in its groove for engaging the flange of the card. The clips are configured to restrain movement of the card in the longitudinal direction, the vertical direction, and a transverse direction perpendicular to the longitudinal and vertical directions when the latches are in locked positions. Such a configuration enables more reliable connections and improves the connector's shock resistance while being compatible with cards having a variety of thicknesses.

Abstract: A configurable electrical connector. The connector has a housing body, a tower extending from the housing body and beyond a mating face, and a latch movably coupled to the housing body and/or tower. The tower is configurable according to a mating component. The tower can be a tower portion formed with the housing body.

The extender has an opening through which the latch can pass for engaging a mating component at the locked position. Such a configuration enables the connector to reliably hold a card taller than a standard card (e.g., according to DDR5 or below), and therefore enable the connector to be compatible with both standard cards and tall cards so as to support different storage capacities and data rates.

Such a configuration enables the connector to provide reliable connections for tall cards, while compatible with physical requirements of industry standards, for example, in length/width directions.

Abstract: A connector for high density, high speed, and high performance electronic systems. The connector has terminals held in a housing. Each terminal has a mating end, a mounting end, and an intermediate portion inbetween. A pair of cuts are disposed on opposite sides of the mounting end such that the mounting end is narrower than the intermediate portion. Each mounting end has a flat surface configured for a solder ball to be attached thereto and narrower than a diameter of the solder ball. This enables the solder ball to be reliably mounted to a contact pad on a circuit board that sized smaller than the solder ball. The contact pad can have a round shape such that a conductive trace can extend in any direction therefrom, which provides flexible routing. 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.

Abstract: 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.

Abstract: A robust electrical connector is provided. The connector includes a housing body, conductive elements held by the housing body, and a slot extending in the housing body and configured to receive a mating component. The housing body has a mating face and a mounting face opposite the mating face. The conductive elements include mating portions curving into the slot and configured to mate with the mating component, and mounting portions extending out of the mounting face. The connector includes a tower extending from an end of the housing body, and a latch pivotably connected to the tower so as to secure the mating component in the slot at a locked position. The tower includes a base portion extending from an end of the housing body, and a cover portion disposed on the base portion. Such a configuration reduces the risk that the tower cracks during operation.

Abstract: Connectors for use with high-speed signals. Mating connectors may include interlocking components that control the mated position of the connectors such that wipe distance can be reduced. These components may be compact such that they can be integrated into connectors with standardized exterior dimensions. They may be integrated into mating guides of the mating connectors. For one of the mating connectors, such a component may be a locking member disposed in and curving out of its guide such that the locking member mates with a matching feature of a component in the guide of the other connector. As the connectors are secured by these components, the conductive elements may be shorter than the lengths required by standards, which reduces the stub and therefore increases signal integrity. Such a configuration provides higher signal integrity at higher speeds, while conforming to standards that constrain mating and mounting interfaces.

Abstract: Surface mount card edge connectors and compact systems using such connectors are provided. A connector has a housing holding conductive elements with a mating face and a mounting face configured to face a side surface of a board. Each conductive element comprises a mating contact portion and a mounting tail extending beyond the mounting face and having an end surface configured to be mounted to a surface pad on a surface of the board. The connector has one or more board locks. Each board lock has a body portion disposed in the housing and a mounting portion having an end surface parallel to the end surfaces of the mounting tails of the conductive elements. Such a configuration enables connectors mounted to opposite sides of a board to be aligned such that a system with these connectors may be more compact.

Abstract: A card edge connector with reduced height that operates reliably. The connector has a housing with a slot extending toward a mounting face. An electronic card can be inserted into the slot until an edge of the card is in a seating plane. The connector has a latch pivotally connected to the housing which may be rotated to eject the card. A reinforcing member may be disposed in the latch with a foot extending between the edge of the card and the mounting face such that, when the latch is rotated, the foot may press against the edge of the card to eject the card. The reinforcing member is both mechanically stronger and thermally more conductive than the latch. Such a configuration enables the seating plane to be closer to the mounting face than that required to meet industry standards.
