Abstract

A plug connector ( 100 ) includes a shell ( 10 ) and a printed circuit board ( 20 ) received in the shell. The printed circuit board includes a grounding layer ( 22 ), a conductive layer ( 21 ) disposed at a first side of the grounding layer, and an insulative layer ( 23 ) disposed therebetween. The conductive layer includes a pair of grounding traces ( 210 ), and a signal channel disposed between and isolated with the grounding traces. The signal channel includes a signal mating portion ( 221 ) disposed at a front portion. Each of the grounding traces includes a grounding mating portion ( 211 ) disposed at a front portion. Each of the grounding mating portions has a front end extending beyond the signal mating portion. The printed circuit board includes a pair of connecting traces ( 214 ). Each of the front ends of the grounding mating portions directly connects with the grounding layer by corresponding one of the connecting traces.

First claim

What is claimed is:

1. An electrical cable connector for mating with a receptacle connector, comprising:
a printed circuit board defining an exterior conductive layer and an interior grounding layer spaced from each other via an insulative layer in a vertical direction,
the exterior conductive layer including a pair of differential signal traces sandwiched between a pair of grounding traces in a transverse direction perpendicular to said vertical direction;
each of said differential signal traces including a front mating portion for mating with a corresponding signal contact of the receptacle connector, a rear connecting portion to electrically and mechanically connect to a corresponding differential signal wire, and a body portion between the front mating portion and the rear connecting portion in a front-to-back direction perpendicular to both said vertical direction and said transverse direction; and
each of said grounding traces including a front mating section located beside the front mating portion in the transverse direction and extending forwardly beyond the front mating portion in the front-to-back direction, and a body section behind the front mating section to mechanically and electrically connect to either a drain wire or a braiding of a cable including said differential signal wires; wherein
along the vertical direction, a pair of front vias mechanically and electrically connect respectively the front mating sections with the grounding layer and a pair of rear vias mechanically and electrically connect respectively the body sections with the grounding layer.

2. The electrical cable connector as claimed in claim 1 , wherein said pair of front vias are located in front of the front mating portions in the front-to-back direction.
