ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of The Invention
The present invention relates to an electrical connector, and particularly to an electrical connector having a well shielding structure for configuring to an insulative housing thereof with satisfactory retention.
2. The Prior Art
Advanced electrical connectors, particularly high frequency electrical connectors, such as IEEE 1394 connectors, are covered with a corresponding shielding for suppression of noise during signal transmission. Some related patents are Taiwan Patents Nos. 85216816, 85212192. Although these connectors as disclosed have a shielding structure for suppression of noise. However, the configuration between the shielding structure and the insulative housing is not stable thus causing unwanted loose engagement therebetween. Additionally, the complication of the shielding structure usually raises manufacturing cost.
SUMMARY OF THE INVENTION
The primary purpose of the present invention is to provide an improved electrical connector which can provide a relatively good positioning effect between the shielding structure and the insulative housing thereof thus preventing loose engagement therebetween.
Another purpose of the present invention is to provide an improved electrical connector having a good shielding effect for suppression of noise.
A further purpose of the present invention is to provide an improved electrical connector having a simple shielding structure easily configured to an insulative housing thereof.
In accordance with one aspect of the present invention, an electrical connector comprising an insulative housing having a first side face defining a first guiding channel therein along a longitudinal direction thereof, a second side face defining a second guiding channel therein along a longitudinal direction thereof, a front face connected to the first side face and the second side face, a rear face opposite the front face and connected to the first side face and the second side face, and a top face connected to the first side face, the second side face, the front face, and the rear face. The rear face has two ends respectively extending beyond the first side face and the second side face and each end defines a slot therein communicating with the guiding channel of the corresponding side face. A metallic shielding has a first side face, a second side face, a front face, and a top face for respectively attaching to the first side face, the second side face, the front face, and the top face of the housing. Two rear tabs respectively extend from the first side face and the second side face of the shielding for engaging within the slots of the rear face of the housing.
