An electrical cable connector includes a contact subassembly having a center contact, a dielectric holder, and an outer contact. The dielectric holder defines a channel that is open at a top side of the dielectric holder. The center contact has a termination region that is held in the channel. The termination region includes a first cable insulation displacement (CID) feature. The outer contact includes a second CID feature extending from a base wall of the outer contact outside of the dielectric holder. The second CID feature extends into the channel through an aperture in the dielectric holder. The first CID feature engages a core conductor of a cable and the second CID feature engages a shield layer of the cable as the cable is loaded into the channel from above the top side of the dielectric holder.
