ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector for insertion of an electronic card, and particularly to an electrical connector having grounding plates soldered to a motherboard.
2. Description of Related Art
FIGS. 6 through 9
disclose a conventional electrical connector soldered to a motherboard
200
for insertion of an electronic card (not shown) thereby establishing electrical connection between the motherboard
200
and the electronic card. The connector comprises an insulating housing
80
, a metal shield
90
and a pair of grounding plates
100
. The grounding plates
100
comprise base portions
102
engaged to the housing
80
, mating portions
104
to be soldered to the motherboard
200
, and contact portions
106
extending from side edges of the base portions
102
. The base portions
102
form a plurality of protrusions
102
a
at two opposite sides thereof engaged to inner walls of receiving slots
84
(see
FIGS. 8 and 9
) defined in the housing
80
, thereby securing the housing
80
to the motherboard
200
. However, the engagement between the grounding plates
100
and the housing
80
is not reliable because the inner walls of the receiving slots
84
are apt to be pierced by the protrusions
102
a
of the grounding plates
100
, causing the housing
80
to separate from the motherboard
200
when the housing is applied a large upward force.
SUMMARY OF THE INVENTION
Accordingly, the object of the present invention is to provide an electrical connector having a pair of grounding plates for reliably securing an insulating housing of the connector to a motherboard.
In order to achieve the object set forth, an electrical connector of the present invention comprises an insulating housing, a plurality of contacts secured to the housing, a shield shielding a top surface of the housing, and a pair of grounding plates assembled at two opposite sides of the housing. The housing defines receiving slots and locking slots at the top surface thereof. The grounding plates comprise base portions retained with the receiving slots of the housing, mating portions soldered to a motherboard, and locking portions secured in the locking slots of the housing to prevent the housing from disengaging with the motherboard.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the preferred embodiment when taken in conjunction with the accompanying drawings.
