Abstract

A cable connector assembly includes: a shielding shell; an inner circuit board received in the shielding shell and defining a number of grounding pads; a cable electrically connecting to the inner circuit board, the cable including an outer boot, plural pairs of differential signal wires, and a number of grounding wires each corresponding to a respective pair of differential signal wires; and a grounding plate electrically connecting with the grounding pads; wherein the grounding plate includes a number of arcuate walls each having a respective receiving room accommodating a corresponding pair of differential signal wires, a notch is defined on a top of each of the arcuate walls, and the grounding wire is soldered in the notch.

First claim

What is claimed is:

1. A cable connector assembly comprising:
a printed circuit board defining a plurality of signal pads and grounding pads alternately arranged with each other along a transverse direction;
a cable electrically and mechanically connected to the inner circuit board, the cable comprising plural pairs of differential signal wires soldered upon the corresponding signal pads, respectively, and a plurality of grounding wires each corresponding to a respective pair of differential signal wires; and
a grounding bracket mechanically and electrically connected to the grounding pads and including a plurality of connecting portions and a plurality of arcuate walls alternately arrange with said soldering portions in said transverse direction, each of the connecting portions seated upon the printed circuit board and each of said arcuate walls having a respective receiving room accommodating a corresponding pair of differential signal wires; wherein
a plurality of grounding wires have corresponding exposed front end sections extending forwardly in a front-to-back direction perpendicular to said transverse direction, and soldered upon the corresponding arcuate walls, respectively, so that the exposed front end sections of said grounding wires and those of the corresponding signal wires are spaced and separated from each other by the corresponding arcuate walls in a vertical direction perpendicular to both said transverse direction and said front-to-back direction.

2. The cable connector assembly as claimed in claim 1 , wherein the exposed front end section of each of said grounding wires is essentially located between the corresponding signal wires of the same pair in an isosceles manner.

3. The cable connector assembly as claimed in claim 2 , wherein each of said arcuate walls forms a cutout to receive the exposed front end section of the corresponding grounding wire.

4. The cable connector assembly as claimed in claim 3 , wherein each of said arcuate walls forms a notch toward the printed circuit board in the vertical direction to receive the exposed front end section of the corresponding grounding wire.

5. The cable connector assembly as claimed in claim 4 , wherein said notch is aligned with the corresponding cutout in said front-to-back direction.

6. The cable connector assembly as claimed in claim 5 , wherein said cutout is located behind the corresponding notch in said front-to-back direction.

7. The cable connector assembly as claimed in claim 5 , wherein said cutout has a similar dimension with the corresponding notch in the transverse direction.

8. The cable connector assembly as claimed in claim 4 , wherein said exposed front end section is soldered in the corresponding notch.

9. The cable connector assembly as claimed in claim 1 , wherein the exposed front end sections of each of the grounding wires and the exposed front end sections of the corresponding signal wires are terminated at different axial positions of the corresponding cable, and wherein the axial position where the exposed front end section of the grounding wire is terminated, is located behind another axial position where those of the exposed front end sections of the corresponding signal wires of the same pair are terminated.

10. The cable connector assembly as claimed in claim 1 , wherein each of said arcuate walls forms a notch bulged toward the printed circuit board in the vertical direction to receive the exposed front end section of the corresponding grounding wire, and said notch extends in said front-to-back direction.

11. A cable connector assembly comprising:
a printed circuit board defining a plurality of signal pads and grounding pads alternately arranged with each other along a transverse direction;
a cable electrically and mechanically connected to the inner circuit board, the cable comprising plural pairs of differential signal wires soldered upon the corresponding signal pads, respectively, and a plurality of grounding wires each corresponding to a respective pair of differential signal wires; and
a grounding bracket mechanically and electrically connected to the grounding pads and including a plurality of connecting portions and a plurality of receiving walls alternately arrange with said soldering portions in said transverse direction, each of the connecting portions soldered upon the printed circuit board and each of said receiving walls having a respective receiving room accommodating a corresponding pair of differential signal wires; wherein
a plurality of grounding wires have corresponding exposed front end sections mechanically and electrically connected to the corresponding receiving walls, respectively, so that said grounding wires and the corresponding signal wires are elevated from the printed circuit board and spaced and separated from the corresponding signal wires by the corresponding receiving wall in a vertical direction perpendicular to said transverse direction; wherein
each of said receiving walls forms a notch to stably receive the corresponding grounding wire along a front-to-back direction perpendicular to both said transverse direction and said vertical direction; wherein
each of said receiving walls forms a cutout out communicating with the corresponding notch to allow the exposed front end section of the corresponding grounding wire to extend therethrough in the vertical direction and into the corresponding notch.

12. The cable connector assembly as claimed in claim 11 , wherein the cutouts is aligned with and located behind the corresponding notches, respectively, in said front-to-back direction, and the cutout is dimensioned similar to the corresponding notch in the transverse direction.

13. The cable connector assembly as claimed in claim 11 , wherein the exposed front end section is soldered in the corresponding notch.

14. The cable connector assembly as claimed in claim 11 , wherein the exposed front end section of each of the grounding wires extends forwardly to be received in the corresponding notch.

15. The cable connector assembly as claimed in claim 14 , wherein the exposed front end sections of each of the grounding wires and the exposed front end sections of the corresponding signal wires are terminated at different axial positions of the corresponding cable, and wherein the axial position where the exposed front end section of the grounding wire is terminated, is located behind another axial position where those of the exposed front end sections of the corresponding signal wires of the same pair are terminated.

16. The cable connector assembly as claimed in claim 14 , wherein the exposed front end section of each of the grounding wires is soldered in the corresponding notch.
