ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector, and particularly to a shielded Surface Mount Type (SMT) electrical connector.
2. Description of the Related Art
Electrical connectors are widely used in various fields to provide permanent or separable connections between electronic products. Many of these electrical connectors have metallic shields cover them for shielding and grounding purposes, thereby ensuring good quality signal transmission between the electronic products.
When Surface Mount Technology (SMT) is used to mount the metallic shield onto a mother circuit board onto which the electrical connector is mounted, retention between the metallic shield, the insulative housing of the connector, and the mother circuit board is an urgent concern to designers and manufacturers of the connector. If the retention is not as good as desired and spaces exist therebetween, the quality of signal transmission through the electrical connector can suffer due to Electromagnetic Inference (EMI), Electrostatic Discharge (ESD), and other problems.
Therefore, an electrical connector providing a reliable mechanical connection between the housing, the shield and the circuit board is desired.
SUMMARY OF THE INVENTION
A major object of the present invention is to provide an electrical connector which provides reliable retention between an insulative housing thereof, a metallic shield thereof and a mother circuit board onto which it is mounted.
An electrical connector in accordance with the present invention includes an insulative housing, a plurality of electrical contacts accommodated in the insulative housing and a metallic shield. The insulative housing comprises a pair of front arms and a pair of rear shoulders. Each front arm defines a recess therein and each rear shoulder defines a slot therein. The metallic shield comprises a pair of side plates each forming a finger retained in the recesses of the front arms and a bending portion extending into the slots of the rear shoulders. Each side plate further comprises a soldering pad flush with the bottom surface of the insulative housing.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
