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.
