ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a memory card connector for use in a mobile computer or digital camera for receiving a memory card, and more particularly to an improved structure of memory card connector, which has a simple structure of memory card ejector mechanism for easy operation by hand to eject the installed memory card.
FIG. 1
shows a memory card connector according to the prior art. This structure of memory card connector comprises a connector body
11
, and an ejector mechanism
12
. The connector body
11
comprises an elongated terminal holder base
111
having rows of pin holes
114
for receiving the pins of a memory card, two side arms
112
and
113
perpendicularly extended from two distal ends of the elongated terminal holder base
111
in same direction, a flat receiving chamber
110
defined between the side arms
112
and
113
for receiving a memory card, two sliding grooves
1121
and
1131
respectively provided at the side arms
112
and
113
at an inner side for guiding a memory card into position, and a plurality of retaining blocks
1122
and
1123
respectively raised from the side arms
112
and
113
at an outer side for securing the ejector mechanism
12
in place. The ejector mechanism
12
is comprised of a flat shell
121
, an ejector rod
122
, and a lever
123
. The flat shell
121
comprises downward coupling boards
1213
,
1214
and
1215
at two opposite lateral sides, an angled flange
1212
at one lateral side defining with the outside wall of one downward coupling board
1215
a space for holding the ejector rod
122
. The lever
123
has a pivot hole
1232
on the middle pivotably connected to a pivot hole
1211
at the flat shell
121
by rivet means, a push portion
1231
at one end, and a stop portion
1233
at an opposite end. The stop portion
1233
of the lever
123
is stopped at one end of the ejector rod
122
inside the angled flange
1212
. The flat shell
121
is covered on the connector body
11
, with the downward coupling boards
1213
,
1214
and
1215
forced into engagement with the retaining blocks
1122
and
1123
(the downward coupling boards
1213
,
1214
and
1215
have coupling holes for engagement with the retaining blocks
1122
and
1123
). This structure of memory card connector is functional, however it is complicated and expensive to manufacture.
SUMMARY OF THE INVENTION
It is one object of the present invention to provide a memory card connector, which has a simple structure of memory card ejector mechanism for ejecting the installed memory card by means of a lever function. It is another object of the present invention to provide a memory card connector, which can easily be assembled without riveting, and positively be operated to eject installed memory card. According to one aspect of the present invention, the memory card connector comprises a connector body for receiving a memory card, the connector body having a coupling rod with a coupling head, a lever turned about the coupling rod at the connector body, and a push bar coupled to one end of the lever for operation by hand to turn the lever about the coupling rod, for causing the lever to push the installed memory card away from the connector body, wherein the lever has a coupling hole coupled to the coupling rod at the connector body, and two coupling flanges suspended in the coupling hole at two opposite sides and forced into engagement with the coupling head of the coupling rod upon a rotary motion of the lever through an angle relative to the coupling rod after insertion of the coupling rod through the coupling hole at the lever. According to another aspect of the present invention, the connector body has a longitudinal track formed integral with one side arm thereof for guiding movement of the push bar, and the push bar has coupling means slidably coupled to the longitudinal track at the connector body.
