Abstract
A high speed cable connector (1) includes a cover (3), a base (80) and a cable assembly (30) mounted between the cover and the base. The cable assembly includes a cable (42) consisting of a plurality of lines (44). Each line has a pair of upper and lower signal wires (442, 444) and a grounding wire (446). Front ends of the lines are sandwiched between upper half (462) and lower half (464) of a spacer (46) to which upper and lower shielding plates (50, 52) are respectively mounted. The upper and lower shielding plates are electrically connected with each other. The upper and lower signal wires are soldered to signal circuitry on top and bottom faces of a printed circuit board (62), respectively. The upper and lower shielding plates have engaging arms (508) soldered to ground circuitry of on the top and bottom faces of the printed circuit board, respectively. Each grounding wire is soldered to a corresponding upper shielding plate. Each pair of upper and lower signal wires is located between two pairs of upper and lower shielding plates, whereby cross-talk between the signal wires of two neighboring lines can be effectively suppressed.
