An electrical connector has rows of contact locations which are signal locations and ground locations where ground locations in one row are programmable independently of ground locations in any other row. A housing member has secured thereto corresponding to each row of contact locations a terminal assembly having signal and ground terminals corresponding to the signal and ground locations in that row. Each terminal assembly has individual terminals on one side of a carrier corresponding to each contact location and a ground plane on the other side of the carrier. A method of making such an assembly is provided. Terminals at ground locations are welded to tab sections of the ground plane located only at ground locations, with such terminals becoming ground terminals. Terminals at signal locations are terminated to signal conductors of transmission cables, while ground conductors of the cables are terminated to the ground plane. A dielectric cover is molded over the terminals and ground plane secured to the carrier, and over end portions of the cables, thereby sealing the terminations, embedding and insulating the terminals rearwardly from the contact sections, and providing support and non-deforming strain relief to the cables. The terminal assemblies have the contact sections extending forwardly therefrom for insertion into respective housing passageways when the assemblies are secured to the housing such as by latches, and the assemblies may be secured to each other prior to securing to the housing such as by projections of each extending through slots in the other and cold-staked. Impedance problems are minimized by the electrical connector, providing for signal transmission of high reliability and uniformity.
