  • Patent number: 11128092
    Abstract: A connector assembly configured for compact, high speed electronic systems. The assembly includes a board connector and a cable connector that may be mated by moving the cable connector in a mating direction perpendicular to a printed circuit board to which the board connector is mounted. The cable and board connectors may latch when mated and may be unlatched and unmated by pulling on a tab at a top of the cable connector in a direction opposite the mating direction. As a result, little clearance is required around the board connector to access the latching components. Such a connector may enable an electronic device with high signal integrity because the connector can be mounted close to an electronic component that processes high speed signals, providing a short, and high integrity signal paths for high speed signals.
