Jack connector, plug connector and connector assembly

摘要

A connector assembly used for balanced transmission includes a jack connector and a card-edge plug connector. The jack connector includes a plurality of pairs of jack-type signal contact elements arranged parallel to each other in an array, a plurality of jack-type ground plate elements arranged alternately with said plurality of pairs of jack-type signal contact elements in said array, a jack-type insulating body made of an electrically insulating material and jack-type ground contact element. The card-edge plug connector includes a plurality of pairs of plug-type signal pads, a plurality of slits arranged alternately with said plurality of pairs of plug-type signal pads, at least one plug-type ground layer and a plurality of signal patterns each extending from a respective one of said plug-type signal pads. The connector assembly has a strip-line structure. Also, virtual ground planes are created at a region between each pair of the plurality of pairs of plug-type signal pads.
