ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electronic card connector, and particularly to an electronic card connector having an improved adapter device.
2. Description of the Art
Commonly, several means are adopted for electrically connecting an electronic card connector to a Printed Circuit Board (PCB). One such means is directly electrically connecting conductive contacts of a card connector with a PCB, as is disclosed in Taiwan application No. 84101873. Another means is using an adapter device, such as an adapter board or the like, which is adapted for electrically connecting a card connector to a PCB, as is disclosed in Taiwan application No. 85214724 and U.S. Pat. No. 5,636,999.
Referring to
FIG. 4
, a conventional card connector
6
comprises an insulative housing
60
, two rows of conductive contacts
62
retained in the housing
60
, a conductive plate
63
covering the housing
60
and an adapter device
70
. The adapter device
70
includes an orientation member
71
and an adapter
75
adapted to be attached to a PCB (not shown). The orientation member
71
defines a receiving space
713
for partially receiving the contacts
62
and the conductive plate
63
. The adapter
75
includes a main body
751
having an unsymmetrical structure, a plurality of conductive terminals
753
retained in the main body
751
and a grounding plate
756
retained on an outside of the main body
751
. Each conductive terminal
753
comprises a curved contacting portion
7532
for engaging with a corresponding conductive contact
62
, and a horizontal tail portion
7534
for soldering to the PCB. The grounding plate
756
forms a vertical section
7562
for contacting the conductive plate
63
, and a horizontal soldering section
7564
for soldering to the PCB. Using this means, the card connector
60
is electrically connected to the PCB by the adapter device
70
.
However, since the electrical connection between the conductive plate
63
and the adapter
75
is plate-to-plate, the conductive contact therebetween does not reliably ensure an effective grounding circuit. Additionally, the adapter
75
is relatively difficult to manufacture due to its unsymmetrical structure.
Hence, an electronic card connector having an improved adapter device is required to overcome the disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION
A first object of the present invention is to provide an electronic card connector having an improved adapter device which provides an effective grounding function; and
A second object of the present invention is to provide an electronic card connector having an improved adapter device which is easy to manufacture.
An electronic card connector in accordance with the present invention is adapted for being mounted onto a PCB. The card connector comprises an insulative housing, a plurality of conductive contacts retained in a corresponding number of passageways defined in the housing, a conductive plate and an adapter device. The conductive plate forms a shielding section covering a top of the housing and a grounding section extending vertically downward from the shielding section. The adapter device comprises an orientation member and an adapter adapted for being mounted onto the PCB. The adapter is constructed to have a symmetric structure, and includes a dielectric body, a plurality of pairs of conductive terminals and grounding contacts retained in opposite sides of the dielectric body for conductively contacting with the conductive contacts and the grounding section of the conductive plate, respectively.
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.
