     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Reference will now be made in detail to the preferred embodiment of the present invention. Referring to  FIGS. 1-3 , a cable connector assembly  100  for mating with a complementary connector (not shown) comprises a connector  6  and a cable  2  having a plurality of wires  20 . Each wire  20  has a front end (not labeled) connected with the connector  6 . 
     The connector  6  comprises a contact module  1  connected with the front ends of the wires  20 , a mounting ring  3  attached to the cable  2 , a shielding shell  4  attached to the mounting ring  3 , and a front shell  5  attached to the shielding shell  4  along a front-to-back direction. The shielding shell  4  and the mounting ring  3  both have a plurality of screw threads to match with each other. The mounting ring  3  is received in the shielding shell  4 . 
     The contact module  1  comprises a mating portion  10  for mating with the complementary connector, and a connecting portion  11  connected with the wires  20 . The contact module  1  is attached to the front shell  5 . The mating portion  10  is received in the front shell  5 . 
     The cable  2  comprises a braided layer  21  surrounding the wires  20 , and an insulative layer  22  coating on the braided layer  21 . 
     The mounting ring  3  comprises a plurality of screwed portions  30 , and a plurality of riveting portions  31  riveted on the cable. The screwed portions  30  have a plurality of screw threads formed on an outer surface thereof for matching with the shielding shell  4 . Each riveting portion  31  is disposed between adjacent two screwed portions  30 . The screwed portions  30  and the riveting portions  31  are spaced one by one along a circling direction around the cable  2 . 
     A part of the braided layer  21  is exposed outside of the insulative layer  22  and the mounting ring  3  is riveted on said part of the braided layer  21 . The mounting ring  3  is electrically connected between the shielding shell  4  and the braided layer  21 . To install the mounting ring  3 , a part of the braided layer  21  is firstly exposed outside of the insulative layer  22 . Then, make said part of the braided layer  21  bent rearwards to surround the insulative layer  22 . Thirdly, install the mounting ring  3  on said part of the braided layer  21  which is bent rearwards to surround the insulative layer  22 . Fourthly, rivet the riveting portions  31  to make the mounting ring  3  attached to the cable  2 . In another option, the mounting ring  3  could be directly riveted on the insulative layer  22 . 
     The shielding shell  4  comprises a receiving room  40  recessed from a front end of the shielding shell  4  for partially receiving the cable  2 , a plurality of side walls  41  surrounding the receiving room  40 , and a thread-portion  42  located at a rear end of the receiving room  40  and having a plurality of screw threads formed on an inner surface thereof for matching with the mounting ring  3 . The thread-portion  42  has a stop-hole  44  defined at a rear end thereof behind the screwed portions  30 . The stop-hole  44  has a diameter smaller than a diameter of the mounting ring  3  and greater than a diameter of the cable  2 . 
     Referring to  FIGS. 1-3 , the front shell  5  is attached to the shielding shell  4  along a front-to-back direction. The front shell  5  cooperates with the shielding shell  4  to form a receiving cavity therebetween for receiving the contact module  1 . The wires  20  are curly or slack within the shielding shell  4 . The front shell  5  comprises a front portion  51  receiving the mating portion  10  and a rear portion  50  attached to the shielding shell  4 . The rear portion  50  comprises a plurality of outer protrusions  501 . The shielding shell  4  comprises a plurality of slots  43  receiving the outer protrusions  501 , respectively. The front shell  5 , the shielding shell  4  and the mounting ring  3  are made of conductive material, so that the contact module  1  does not need another shielding structure for suppressing electromagnetic interference. The wires  20  are long enough to ensure that the front shell  5  and the contact module  1  do not interfere the screwing movement of the shielding shell  4 . When the connector assembly  100  is assembled well, the wires  20  are shrunk to be curly and secured in the shielding shell  4 . 
     To manufacture the cable connector assembly  100 , firstly, provide the cable  2  with a plurality of wires  20 . Secondly, provide the shielding shell  4  with the receiving room  40  and make the cable  2  pass into the shielding shell  4  through the receiving room  40 , the shielding shell  4  has a plurality of screw threads. Thirdly, provide the mounting ring  3  having a plurality of screw threads for matching with the shielding shell  4  and mount the mounting ring  3  to the cable  2 . Fourthly, provide the contact module  1  for mating with the complementary connector, and connect the contact module  1  with the front ends of the wires  20 . Fifthly, provide the front shell  5 , and attach the contact module  1  to the front shell  5 . Sixthly, screw the shielding shell  4  to the mounting ring  3 , with the front ends of the wires  20 , the front shell  5  and the contact module  1  exposed outside of the shielding shell  4 . Seventhly, attach the front shell  5  to the shielding shell  4  along a front-to-back direction with the wires  20  shrunk to be curly and secured in the shielding shell  4 . 
     It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
