    • A connector assembly for connecting to differential signal circuits on at least one circuit board may be of the docking type or the interposer type. A housing of the connector has transversely and longitudinally extending walls that define a plurality of cavities that extend completely through the housing. Terminal assemblies with at least one differential signal pair are received in the cavities with tail portions on at least one end of the differential pairs to connect to a circuit board. The connector housing has conductive surfaces and a plurality of ground terminal members are disposed along the transverse walls or the longitudinal walls, or both, for connecting to ground circuits in the circuit board. The ground terminal members each have a plurality of ground terminals, which are disposed along the walls at intermediate or diagonal positions relative to the differential signal pairs, such as adjacent to four differential signal pairs. Such placement of the ground terminal members also subdivides the differential signal pairs into groups or sets. This interstitial ground terminal arrangement also serves to keep the impedance at the connector-circuit board interface relatively uniform for high speed signals in the differential pairs.
    • 用于连接到至少一个电路板上的差分信号电路的连接器组件可以是对接类型或插入器类型。 连接器的壳体具有横向和纵向延伸的壁,其限定了完全延伸穿过壳体的多个空腔。 具有至少一个差分信号对的端子组件被容纳在空腔中,其中尾部在差分对的至少一端连接到电路板。 连接器壳体具有导电表面,并且多个接地端子构件沿着横向壁或纵向壁或两者设置,用于连接到电路板中的接地电路。 接地端子构件各自具有多个接地端子,其沿着相对于差分信号对的中间或对角线位置沿着壁布置,例如与四个差分信号对相邻。 接地端子构件的这种放置还将差分信号对细分成组或组。 这种间隙接地端子装置还用于保持连接器电路板接口处的阻抗对差分对中的高速信号保持相对均匀。
