Abstract

A cable connector assembly (100) used in high frequency signal transmission filed includes an insulative housing (2), a conductive terminals (3) retained in the housing, a number of wires (4) arrayed in a row and electrically connecting the terminals, and a conductive shell (5). The wires comprise at least one signal wire (40b) each comprising one or more conductive cores (401b) at the innermost thereof, and a grounding layer (403b) surrounding and shielding said core. The conductive shell comprises a base portion (510, 511, 520) shielding said housing and a soldering portion (521) integral with and behind said base portion. Each grounding layer abuts against and is soldered with said soldering portion of the shell, thereby simplifying grounding path.

Claims

1. A cable connector assembly, comprising:

an insulative housing adapted for mating with a complementary connector;

a plurality of conductive terminals held in the housing;

a plurality of wires arrayed in a row along a longitudinal direction and electrically connecting corresponding terminals, said wires comprising at least one signal wire each comprising one or more conductive cores at the innermost thereof and a grounding layer surrounding and shielding said cores; and

a conductive shell including a base portion shielding said housing and a soldering portion integral with and behind said base portion, wherein each grounding layer abutting against and soldered with said soldering portion of the conductive shell.

2. The cable connector assembly according to claim 1, wherein the soldering portion is closer than said base portion of the shell to said grounding layer in a vertical direction perpendicular to said longitudinal direction.

3. The cable connector assembly according to claim 2, wherein the soldering portion of the shell is rectangular and lies in a surface parallel to said wires.

4. The cable connector assembly according to claim 1, wherein the soldering portion of the shell locates behind the insulative housing.

5. The cable connector assembly according to claim 4, wherein the insulative housing defines a receiving space at the rear end of the housing for receiving said soldering portion.

6. The cable connector assembly according to claim 1, wherein said grounding layer is a metal braid layer, and each grounding layer surrounds a pair of conductive cores.

7. The cable connector assembly according to claim 6, wherein said wires comprise at least one power wire each composed of a jacket at the outmost thereof and a conductive core at the innermost thereof.

8. The cable connector assembly according to claim 1, wherein said conductive shell comprises an upper shell and a lower shell separated from the upper shell, and said soldering portion is integrative with the lower shell.

9. The cable connector assembly according to claim 8, wherein a plurality of fingers are formed in the upper shell and the lower shell, and a plurality of through holes for engaging with said fingers are defined in the housing.

10. The cable connector assembly according to claim 1, wherein a pair of ear portions are defined in both lateral side of the housing.

11. The cable connector assembly according to claim 10, wherein a receiving space is defined between the pair of ear portions for receiving the soldering portion of the shell.

12. The cable connector assembly according to claim 8, wherein the upper shell comprises a base portion facing the terminals, a pair of wing portions engaging with the housing and lower than the base portion of the upper shell.

13. The cable connector assembly according to claim 12, wherein a Kapton tape is stuck to an inner surface of the base portion of the upper shell to insulate the upper shell from said terminals and wires.

14. The cable connector assembly according to claim 1, wherein a tin stick placed on the grounding layer is heated for soldering said grounding layer with said soldering portion of the shell.

15. The cable connector assembly according to claim 1, wherein the soldering portion is below the wires and wide enough to supporting all the wires.

16. A cable connector assembly comprising:

an insulative housing adapted for mating with a complementary connector;

a plurality of conductive terminals held in the housing;

a plurality of wires arrayed in a row along a longitudinal direction and electrically and mechanically connecting corresponding terminals, said wires comprising signal wires each comprising at least one core at the innermost thereof to connect to the corresponding terminal and a grounding layer surrounding and shielding said core; and

a conductive shell including a cover portion downwardly shielding said housing and joint portions between the wires and the corresponding terminals;

wherein

an insulator is sandwiched between the cover portion and the joint portions for isolation while the cover portion directly mechanically and electrically connecting to the grounding layer.
