Patent ID: 7690930

Claim:
A connection between an electrical cable for connecting electronic devices and a target printed circuit board (“PCB”) for high data transfer speed and high signal frequency, comprising: electrical cable for high speed data transfer, including non-critical wires, critical data wires, a ground conductor, an internal conductive shield surrounding the non-critical wires, the critical data wires, and the ground conductor, and an external threaded shield throughout a periphery surrounding the internal conductive shield, the external threaded shield being not electrically connected to the internal conductive shield, the critical data wires being both impedance matched and length balanced with each other, and an outermost insulating material around the external threaded shield; and an interconnection PCB with a top surface connected to an end portion of said electrical cable, comprising critical first traces and reference ground second traces extending in a lengthwise direction from the end portion of said electrical cable, each of said critical first traces being impedance matched and length balanced with each other, and each of said critical first traces being connected to a corresponding critical data wire of the end portion of said electrical cable by means of galvanic connections configured to maintain a continuity of electrical impedance between the critical data wires of said electrical cable and the target PCB of a target electronic device, wherein said electrical cable is fixed to said interconnection PCB at a first fixing point on the top surface via an end portion of the external threaded shield, wherein said electrical cable is fixed to said interconnection PCB at a second fixing point on the top surface via any of an end portion of the ground conductor and an end portion of the internal conductive shield, the second fixing point being spaced and electrically disconnected from the first fixing point in the lengthwise direction of the first and second traces, and wherein the galvanic connections connecting each of said critical first traces to a corresponding critical data wire of said electrical cable forms a third fixing point fixing said electrical cable to said interconnection PCB.
