The connector is electrically connected with the cables and has an insulative housing and a number of electrical contacts retained to the insulative housing. The electrical contacts include plural signal contacts electrically connected with the conductive wires, plural grounding contacts, and plural grounding pins backwardly integrally extending from the grounding contacts. The grounding pin is disposed between the outer jacket and the grounding layer to electrically connect with the grounding layer. ## Claims ### Claim 1 A cable connector assembly comprising: an insulative housing defining a plurality of passageways extending along a front-to-back direction; a plurality of contacts disposed in the corresponding passageways, respectively, said contacts including differential pair contacts and grounding contacts alternately arranged with each other along a transverse direction perpendicular to said front-to-back direction, each of said contacts including a front mating section, a rear tail section and a middle retention section; a connecting portion located and exposed behind the tail sections of said contacts and essentially extending along the transverse direction, said connecting portion further forwardly connected to the tail sections of the grounding contacts while spaced from the tail sections of the differential pair contacts; and a cable located behind the housing and including a plurality of differential pair sets each including a pair of differential wires and a grounding braiding surrounding the pair of differential wires; wherein the pair of differential wires form exposed front ends respectively soldered to the tail sections of the corresponding differential pair contacts while the grounding braiding forms an exposed front end soldered to the connecting portion; wherein said connecting portion further includes unitarily a plurality of rearwardly extending tabs each extending into the differential pair set to mechanically and electrically connect to the grounding braiding of the corresponding differential pair set; wherein each of said rearwardly extending tabs extends into and is protectively hidden within a space between the grounding braiding and an outer jacket of the corresponding differential pair set. ### Claim 2 (depends on 1) The cable connector assembly as claimed in claim 1, wherein the jacket includes a bulged portion to accommodate the tab therein. ### Claim 3 (depends on 1) The cable connector assembly as claimed in claim 1, wherein said tab is coplanar with the connecting portion. ### Claim 4 (depends on 1) The cable connector assembly as claimed in claim 1, wherein an insulative spacer is integrally molded upon the contacts between the tail sections and the retention sections so as to seal a rear side of the housing to uncover the corresponding passageways. ### Claim 5 (depends on 1) The cable connector assembly as claimed in claim 1, wherein the connecting portion is unitarily connected to and formed with the grounding contacts. ### Claim 6 A cable connector assembly comprising: an insulative housing defining a plurality of passageways extending along a front-to-back direction; a plurality of contacts disposed in the corresponding passageways, respectively, said contacts including differential pair contacts and grounding contacts alternately arranged with each other along a transverse direction perpendicular to said front-to-back direction, each of said contacts including a front mating section, a rear tail section and a middle retention section; a connecting portion located and exposed behind the tail sections of said contacts and essentially extending along the transverse direction, said connecting portion further forwardly unitarily connected to and formed with the tail sections of the grounding contacts while spaced from the tail sections of the differential pair contacts; and an insulative spacer being integrally molded upon the contacts between the tail sections and the retention sections so as to seal a rear side of the housing to uncover the corresponding passageways; further including a cable located behind the housing and including a plurality of differential pair sets each including a pair of differential wires and a grounding braiding surrounding the pair of differential wires, wherein the differential wires are soldered to the tail sections of the corresponding differential pair contacts, respectively, and the grounding braiding is soldered to the connecting portion; wherein; a plurality of tabs rearwardly extend unitarily from the transversely extending connecting portion, and the grounding braiding of the corresponding differential pair set is connected to the corresponding one of said tabs; wherein each of the differential pair set includes an outer jacket with a projecting portion protectively enclosing said corresponding one of said tabs. ### Claim 7 (depends on 6) The cable connector assembly as claimed in claim 6, wherein the rearwardly extending tab is inserted into and protectively hidden in a space between the grounding braiding and said outer jacket of the corresponding differential pair set.
