at least one cable electrically connected to the connecting end, the at least one cable comprising a number of core wires, the core wires comprising a first group of core wires and a second group of core wires extending beyond the first group of core wires, the first group of core wires soldered to the first row of pads, the second group of core wires soldered to the second row of pads; and
an insulative member covering and isolating a soldering area where the first group of core wires are soldered;
wherein the insulative member is elongate, the insulative member comprising a covering portion covering the soldering area of the first group of core wires and a depression portion through which the second group of core wires passes.

2. An electrical connector assembly comprising:
a cage;
a printed circuit board enclosing within the cage and defining opposite first and second surfaces in a vertical direction, a first row of conductive pads and a second row of conductive pads formed on the first surface, the second row of pads located in front of the first row of pads in a front-to-back direction perpendicular to the vertical direction;
a first group of core wires soldered to the corresponding first row of conductive pads, respectively;
a second group of core wires soldered to the corresponding second row of conductive pads, respectively; and
a first conductor member soldered upon the first row of pads and including a plurality of extrusion portions and a plurality of depression portions alternately arranged with each other along a transverse direction perpendicular to both the vertical direction and the front-to-back direction; wherein
a plurality of oblique portions are formed between the corresponding extrusion portions and the depression portions, respectively, to support the second group of core wires for spacing the second group of core wires away from the printed circuit board with a distance so as to have the first group of core wires and the second group of core wires alternately, along the transverse direction, arranged with each other in an offset manner in the vertical direction around the first conductor member.

3. The plug connector assembly as recited in claim 1 , wherein each of the core wires comprises a pair of center conductors, an insulative layer enclosing the pair of center conductors, and a ground wire.

4. The plug connector assembly as recited in claim 3 , further comprising a first conductor member disposed at the first group of the core wires, and wherein the first row of pads comprises plural pairs of first signal pads and a respective first ground pad disposed between two adjacent pairs of first signal pads, the first conductor member being electrically connected to the first ground pads, each ground wire of the first group of core wires being electrically connected to the first conductor member.

5. The plug connector assembly as recited in claim 4 , wherein the first conductor member defines a number of notches for receiving the corresponding ground wires of the second group of core wires.

6. The plug connector assembly as recited in claim 4 , further comprising a second conductor member disposed at the corresponding second group of the core wires, and wherein the second row of pads comprises plural pairs of second signal pads and a respective second ground pad disposed between two adjacent pairs of second signal pads, the second conductor member being electrically connected to the second ground pads, each ground wire of the second group of core wires being electrically connected to the second conductor member.

7. The plug connector assembly as recited in claim 6 , wherein the second ground pads and the second signal pads are offset from corresponding first ground pads and the first signal pads in a transverse direction.

8. The plug connector assembly as recited in claim 1 , wherein the second row of pads are located in front of the first row of pads in a front-to-back direction, and the insulative member covers the first row of pads and the corresponding first group of core wires in a vertical direction perpendicular to the front-to-back direction.

9. The plug connector assembly as recited in claim 8 , further including a first conductor member soldered upon the first row of pads and connected to ground wires of the first group of core wires, and a second conductor member soldered upon the second row of pads and connected to ground wires of the second group of core wires, wherein the insulative member is mounted upon said side of the PCB after the first group of core wires are soldered to the first row of pads while before the second group of core wires are soldered to the second row of pads.

10. The plug connector assembly as claimed in claim 9 , wherein the insulative member is located between the first conductor member and the second conductor member in the front-to-back direction.

11. The plug connector assembly as claimed in claim 10 , wherein said first conductor member includes a plurality of extrusion portions and depression portions alternatively arranged with each other in a transverse direction perpendicular to both the front-to-back direction and the vertical direction, and a plurality of oblique portions are located between the neighboring extrusion portions and depression portions to respectively support the corresponding ones of the second group of core wires so as to have the core wires of the second group of core wires farther from the printed circuit board while the core wires of the first group of core wires closer to the printed circuit board in the vertical direction in an offset manner around the first conductor member.

12. The plug connector assembly as claimed in claim 10 , wherein the insulative member is mounted to the side of the PCB after the first conductor member is soldered to the first row of pads while before the second conductor member is soldered to the second row of pads.

13. A method of assembling a plug connector assembly, comprising the steps of:
