Abstract: A card edge connector with a locking system, which may include a locking member integrally formed with a connector housing. The locking member may deflect upon insertion of an edge of a board into the connector and spring back to engage an opening in the board. The locking member and the opening in the board may have perimeters that are rounded, allowing relative rotation about an axis through the opening even though the board is locked within the connector. Such a configuration may provide a simple and secure locking system. Such a configuration may support connecting two parallel boards, each with a card edge connector, through a riser board with opposite ends inserted into the two connectors. Relative rotation of the board with respect to the connectors enables skew, in a direction parallel to the surfaces of the parallel boards, while securing each of those boards to the riser board.

Abstract: A configurable electrical connector. The electrical connector includes conductors held by a housing. Contact tails of the conductors extend from a mounting face of the housing therethrough. The mounting face of the housing includes a slot. In some embodiments, the slot exposes portions of ground conductors of the connector and receives a member coupled with the exposed portions of the ground conductors such that the electrical connector can meet high performance requirements. The member may be inserted into or molded in the slot. In some embodiments, the slot may or may not receive a member that is insulative when the electrical connector does not need to meet the high performance requirements. Such a configuration enables the same connector to be compatible with multiple performance protocols.
