ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical card connector mounted onto a printed circuit board (PCB), and particularly to an electrical connector having metal ears mounted firmly thereon.
2. Description of the Prior Art
As the popularity of notebook computers increases, integrated circuit (IC) cards are becoming more common for increasing storage capacity or for interfacing the notebook computers with other devices. Card connectors are commonly used to connect motherboards of the computers with the cards. Most current IC cards and card connectors conform to the standard of Personal Computer Memory Card International Association (PCMCIA).
Referring to FIG.
6
&
FIG. 8
, a conventional electrical card connector includes an insulative housing
80
, a shell
90
and a metal ear
700
connected with the shell
90
. Also referring to FIG.
7
&
FIG. 9
, the metal ear
700
comprises a base
702
, an engaging section
704
and a flat
706
. The base
702
includes a plurality of embosses
702
a
on either side of the base. When the metal ear
700
is assembled onto the lower face
82
, the embosses
702
a
intervene with a dowel slot
84
defined in the insulative housing
80
so that the metal ear
700
can be fixed into the insulative housing
80
.
However, the dowel slot
84
extends from a lower face
82
of the insulative housing
80
to a top face
86
but not through the top face
86
. The metal ear
700
connects the insulative housing
80
only via embosses
702
a
. When the insulative housing
80
comes under an upward force, the engaging section
704
of the metal ear
700
can lacerate the dowel slot
84
of the insulative housing
80
easily and make the metal ear
700
disengage from the insulative housing
80
though the engaging section
704
of the metal ear
700
is soldered onto the PCB
200
.
Hence, an improved electrical card connector is desired to overcome the disadvantages of the prior art card connector.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an electrical card connector whose metal ear can be assembled to its insulative housing firmly.
An electrical card connector in accordance with the present invention comprises an insulative housing comprising a long base and two side arms respectively connected with the long base, each side arm having an upper recess and a lower recess, a protrusion on the upper recess, and a first oriented groove on an inner wall surface thereof, a plurality of terminals received in the insulative housing; and a pair of metal ears each comprising a body received in the side arm, an engaging section received in the lower recess for soldering onto a printed circuit board (PCB), a buckle section received in the upper recess of the side arm, a bent portion secured in the first oriented groove of the side arm, the buckle section having an opening engaged with the protrusion, the engaging section and the buckle section cooperatively clamping to the side arm.
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.
