    • An orthogonal backplane connector systems having midplane footprints that provide for continuity of impedance and signal integrity through the midplane and allow for the same connector to be coupled to either side of the midplane. This design creates an orthogonal interconnect without taking up unnecessary PCB real estate. The midplane circuit board may include a first differential signal pair of electrically conductive vias disposed in a first direction, and a second differential signal pair of electrically conductive vias disposed in a second direction that is generally orthogonal to the first direction. The first and second differential signal pair of electrically conductive vias are electrically connected through the midplane circuit board. Each pair may be associated with and be located in between ground vias. A ground via that is large relative to the signal vias may be provided. The second signal vias may comprise a shared signal via, receiving a contact from respective connectors connected to each side of the midplane circuit board. The second signal vias may comprise partial signal vias, extending from one or more sides partially into the midplane circuit board. The signal pairs may be offset from a via array centerline formed by the ground vias to correspond with mating ends of signal contacts of an electrical connector that likewise jog away from a centerline of a respective contact column of the connector.
    • 正交背板连接器系统具有中间面积,其通过中平面提供阻抗和信号完整性的连续性,并允许相同的连接器耦合到中平面的任一侧。 该设计创建了一个正交互连,而不占用不必要的PCB空间。 中间平面电路板可以包括沿第一方向设置的导电通孔的第一差分信号对和沿大致正交于第一方向的第二方向设置的第二导电通孔对。 导电通孔的第一和第二差分信号对通过中平面电路板电连接。 每对可以与地面通孔相关联并位于其间。 可以提供相对于信号通路较大的接地通孔。 第二信号通孔可以包括共享信号通孔,从连接到中平面电路板的每一侧的相应连接器接收触点。 第二信号通孔可以包括从一个或多个侧面部分地延伸到中平面电路板中的部分信号通路。 信号对可以从由接地通孔形成的通孔阵列中心线偏移,以对应于同样从连接器的相应接触柱的中心线移开的电连接器的信号触头的配合端。
