ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cable connector assembly used in telecommunications, and particularly to a cable connector assembly with an improved grounding structure.
2. Description of the Related Art
A cable connector assembly used for data transmission can often be adversely affected in its function by Electro Magnetic Interference (EMI), which can impede the transmission of information. To protect the cable connector assembly from EMI, a conventional solution is to ground a shielding braid of a cable to a corresponding connector shield. Referring to
FIG. 4
, a grounding wire
741
of a braid (not labeled) of a cable
74
is soldered to an outer surface of a circular metal strip
731
of a connector shield (not labeled) inside a transparent insulation
72
of a conventional connector
70
. However, such a configuration leads to an irregular surface of the strip
731
and a soldering point
71
of the grounding wire
741
is often destroyed during injection molding the insulation
72
thereon. Additionally, the soldering point
71
is not attractive in appearance in the final product.
Hence, an improved cable connector assembly with a grounding structure which overcomes the above-mentioned disadvantages of a conventional cable connector assembly is required.
SUMMARY OF THE INVENTION
A first object of the present invention is to provide a cable connector assembly with an improved grounding structure wherein a grounding wire of a cable braid is more reliably connected to a connector shield of the grounding structure.
A second object of the present invention is to provide a cable connector assembly with an improved grounding structure wherein assembly of the cable connector assembly is more convenient.
A further object of the present invention is to provide a cable connector assembly with an improved grounding structure which has a more attractive appearance.
To achieve the aforementioned objects, a cable connector assembly comprises a shielded cable set and an electrical connector. The electrical connector includes a dielectric housing retaining a plurality of terminals therein and a shield including an upper shell and a lower shell defining a receiving space therebetween for receiving the dielectric housing therein. The lower shell has a top plate, a bottom plate and side plates each defining a soldering tab thereon. A cable set comprises a plurality of signal wires and a grounding wire connected to a shielding braid which surrounds the signal and grounding wires. The grounding wire is soldered to a soldering tab of the lower shell inside the receiving space and the signal wires are soldered to a corresponding terminal for establishing an electrical connection therebetween.
