Abstract: An ultra high speed signal cable connector includes an insulating housing, a PCB fixedly mounted inside the insulating housing, and at least one row of cables without grounding wires welded to the PCB. The end portion of a connecting finger of the PCB extends out of the insulating housing, and the PCB is provided with a signal bonding pad and a grounding wire bonding pad. Each cable without grounding wires includes a plurality of electric wires, a conductive jacket for wrapping the plurality of electric wires together, and an insulating jacket wrapped on the outer layer of the conductive jacket. Each electric wire includes a core wire and an insulating layer wrapped on the outer layer of the core wire. One ends of the core wires are welded on the signal bonding pad; a section of insulating jacket is stripped from the foremost end of each cable without grounding wires to expose the conductive jacket. The conductive jackets are electrically and fixedly connected to the grounding wire bonding pad.
