RJ modular connector having grounding mechanism

Claim 1

A RJ modular connector comprising: a housing defining a plug receiving section and a terminal insert receiving section; and a terminal insert received in said terminal insert receiving section and comprising a first printed circuit board (PCB), a plurality of signal terminals mounted to the PCB and between a pair of grounding terminals; wherein the PCB defines a conductive signal trace formed on a first side thereof and a plurality of grounding traces on a second side thereof, each grounding trace being defined between a selected pair of said signal terminals, a grounding layer and a pair of ground pads being disposed on the PCB for establishing an electrical connection between the grounding terminal and the grounding traces for reducing the noise between the selected pairs of signal terminals; and wherein the pair of grounding pads being disposed at an outer most side edge of the PCB to surround the grounding traces, the signal traces and the signal terminals; and wherein the RJ modular connector further comprising a second PCB having a second conductive signal trace and a plurality of second grounding traces on opposite sides thereof; and wherein the plurality of signal terminals and the two grounding terminals are sandwiched between the first and second printed circuit boards; and wherein said ground pads respectively define a pair of vias for electrically connecting with the grounding layer; and wherein each of said PCB defines a plurality of vias corresponding to each grounding trace to electrically connecting the grounding layers and the grounding traces; and wherein said conductive trace is rectangular and at least one via is formed on one of the shorter sides of the conductive trace; and wherein each of the grounding terminals comprises a retaining beam attached on the ground pads; and wherein the retaining beam defines a plurality of barbs to secure the terminal insert into the housing.
