ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to electrical connectors, and particularly to an electrical connector having a shielding plate.
2. Prior Art
Nowadays, electrical signal transmissions tend to be high speed and high frequency which easily cause electromagnetic interference between electronic devices. A conventional electrical connector normally has a metal shielding plate grounded to prevent electromagnetic interference during signal transmitting, thereby assuring stable signal transmitting.
FIG. 1
shows a conventional electrical connector
2
. The electrical connector
2
includes a plurality of grounding terminals
3
and two shielding plates
4
. Each shielding plate
4
has a plurality of grounding tabs
5
which are bent to electrically contact corresponding grounding terminals
3
thereby reducing electromagnetic interference.
However, the electrical contact between the grounding terminals and the grounding tabs is not secure in use. When the grounding terminals or the grounding tabs are deformed or the connector
2
is under vibration, the electrical contact therebetween is adversely affected.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an electrical connector having a shielding plate for providing secure grounding paths thereby preventing electromagnetic interference.
To achieve the above-mentioned object, an electrical connector in accordance with the present invention includes a housing and a pair of shielding plates attached to opposites sides of the housing. The housing has opposite side walls, a slot between the side walls and a plurality of terminal passages in communication with the slot. Each side wall has a plurality of retainers for securing one of the shielding plates. Each plate has a plurality of grounding terminals received in the terminal passages of the housing for electrically mating with a complementary connector. A plurality of soldering tails extends from each of the shielding plates opposite to the grounding terminals for being soldered to and securely electrically connected with a printed circuit board.
Other objects, advantages and novel features of the present invention will be drawn from the following detailed description of a preferred embodiment of the present invention with attached drawings, in which:
