US Patent 10186794 Connector system with adapter

A connector system includes a main board and an interposer board. The main board and the interposer board are each configured to mate to a separate connector and are connected together by vias. The vias can provide an electrical path from the interposer board to the main circuit board so that a first connector mounted on the interposer board can be positioned directly in line with a second connector mounted on the main circuit board. The interposer helps make the routing out of signal traces from the two connector simpler while reducing the need for additional layers on the main board. Two connectors can be press-fit mounted to the main board and the interposer board in a belly-to-belly configuration.
