a cable including a plurality of coaxial wires to electrically connect with corresponding contacts, each coaxial wire including an inner conductor, an inner insulative layer enclosing the inner conductor, a braiding layer enclosing the insulative layer, and an outer insulative layer enclosing the braiding layer;
a connecting member electrically connected with the parts of the grounding soldering portion and the braiding layers of the coaxial wires;
wherein the grounding contact defines a pair of grounding soldering portion, and one of the grounding soldering portions is disposed in the upper row of soldering portions, the another of the grounding soldering portions is disposed in the lower row of soldering portions;
wherein the connecting member includes a u-shaped main body extending along a horizontal direction and an extension portion forwardly extending from each side of the main body to be electrically connected with the corresponding grounding soldering portion of the grounding contact;

a fixing member, the fixing member includes a holding portion and a projecting portion rearwardly extending from the holding portion for mounting the main body of the connecting member thereon; and
a spacer, the spacer includes a sidewall along a vertical plane, an upper sidewall forwardly extending from an upper end of the sidewall and a lower sidewall forwardly extending from a bottom end of the sidewall, the projecting portion of the fixing member is held between the upper sidewall and the lower sidewall.

2. The cable connector assembly according to the claim 1 , wherein the extension portion is electrically connected with the grounding soldering portion by welding way.

3. The cable connector assembly according to the claim 1 , wherein the holding portion of the fixing member defines a plurality of railing portion, and a receiving groove formed between the adjacent railing portions to receive the soldering portion of the contacts.

4. The cable connector assembly according to claim 1 , wherein both of the upper and lower sidewall define a plurality of holding slots for holding a top portion of the corresponding railing portion.

5. A cable connector assembly comprising: an insulative housing;
a plurality of contacts disposed in the housing and side by side arranged with one another along a transverse direction while each of said contacts extending along a front-to-back direction perpendicular to said transverse direction, said contacting being categorized with two differential pairs of high speed signal contacts by two sides of a grounding contact in said transverse direction, each of said contacts including a front contacting portion and a rear soldering portion along the front-to-back direction wherein the grounding contacts forms two rear soldering portions, the front contacting portions being arranged in one front row along the transverse direction while the soldering portion being arranged in two rear rows each spanning in said transverse direction while said two rear rows being spaced from each other in a vertical direction perpendicular to the front-to-back direction, in each rear row said soldering portions including two soldering portions of one pair of high speed signal contacts and one soldering portion of the grounding contact;
a metallic grounding bar including a main body and an extension portion forwardly extending from the main body and located at a different level with regard to the main body in the vertical direction;
a cable including a plurality of differential coaxial wires each including an inner conductor, an inner insulative layer, a braiding layer and an outer insulative layer sequentially circumferentially surrounding one another; wherein
the extension portion is soldered upon the grounding soldering portion of the grounding contact while the inner conductors are soldered upon the soldering portions of the corresponding high speed signal contacts, and the braiding layer is soldered upon the main body, respectively;
a fixing member on a rear side of the housing for regulating the soldering portions of the contacts, the fixing member includes a holding portion and a projecting portion rearwardly extending from the holding portion for mounting the main body of the metallic grounding bar thereon; and
a spacer, the spacer includes a sidewall along a vertical plane, an upper sidewall forwardly extending from an upper end of the sidewall and a lower sidewall forwardly extending from a bottom end of the sidewall, the projecting portion of the fixing member is held between the upper sidewall and the lower sidewall.

6. The cable connector assembly as claimed in claim 5 , wherein said grounding bar includes two arms spaced from each other in the vertical direction to comply with the two rear rows of the rear soldering portions of the contacts, respectively.

7. The cable connector assembly as claimed in claim 6 , wherein said grounding bar forms a U-shaped configuration with said two arms thereon.

8. The cable connector assembly as claimed in claim 6 , wherein said grounding bar includes two said extension portions respectively soldered upon the corresponding grounding soldering portions in two different rear rows, respectively.

9. The cable connector assembly as claimed in claim 6 , wherein the wires are arranged in two rows spaced from each other in the vertical direction to comply with the two rear rows of the soldering portions of said contacts in the vertical direction.

10. A cable connector assembly comprising:
an insulative housing;
a plurality of contacts disposed in the housing and side by side arranged with one another along a transverse direction while each of said contacts extending along a front-to-back direction perpendicular to said transverse direction, said contacting being categorized with two differential pairs of high speed signal contacts by two sides of a grounding contact in said transverse direction, each of said contacts including a front contacting portion and a rear soldering portion along the front-to-back direction, the front contacting portions being arranged in one front row along the transverse direction while the soldering portion being arranged in two rear rows each spanning in said transverse direction while said two rear rows being spaced from each other in a vertical direction perpendicular to the front-to-back direction, in each row said soldering portions including at least two soldering portions of one pair of high speed signal contacts wherein one of said two rear rows further includes one soldering portion of the grounding contact;
