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: 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.

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.
