ABSTRACT:
FIELD OF THE INVENTION
The present invention relates in general to a device for receiving and connecting a memory card, and in particular to a device for receiving and connecting a SIM (Subscriber Identification Module) card used in a portable telephone set.
DESCRIPTION OF THE PRIOR ART
Referring to
FIG. 5
, a perspective view of a portable telephone set with its user interface module removed to reveal the upper surface of the transceiver
50
is shown. A recessed portion
52
is formed on the upper surface and a cartridge-shaped card receiving case
54
is slidably mounted on the long edges of the recessed portion
52
. The card receiving case
54
is so designed that it will be slid and raised in a direction indicated by the arrow when the central upper surface
51
is pressed and pushed rightward, and thus is convenient for inserting a memory card, i.e. a SIM card
53
. In this design, the printed circuit board (not shown), which includes an electrical contact for connecting to the electrical contact of the SIM card
53
when it is loaded, is welded directly on the backside of the transceiver
50
corresponding to the recessed portion
52
. Thus, a larger area of the printed circuit board is occupied, and loading the SIM card
53
is not convenient for users.
In
FIG. 6
, another design of the SIM card receiving mechanism is shown. A recessed portion
62
is also formed on the upper surface of the transceiver
60
for receiving the SIM card
63
. A cover plate
64
covers the recessed card-receiving portion
62
. The cover plate
64
is rotatably disposed on the edge of the recessed card-receiving portion
62
. This card receiving mechanism is convenient for loading a SIM card. However, as the card receiving portion
62
is directly disposed on the printed circuit board (not shown), a larger area of the printed circuit board is also used.
SUMMARY OF THE INVENTION
It is therefore an object of the invention to provide a memory card receiving and connecting device which occupies a smaller area of the printed circuit board of the transceiver of a portable telephone set and is convenient for loading a memory card therein.
According to the invention, a rectangular chamber, which is a recessed portion, is formed on the upper surface of the transceiver and has a plurality of slots formed on the bottom thereof. A plurality of contacts are disposed on a base plate which is disposed under the rectangular chamber and above a printed circuit board of a transceiver of a portable telephone set without contacting directly with the printed circuit board. Each of the contacts protrudes from the corresponding slot of the rectangular chamber to couple to the electrical contacts of a SIM card, and has an extended end electrically connected to the contacts of the printed circuit board. The recessed rectangular chamber has an inclined plane disposed at the open short edge of the chamber.
According to an aspect of the invention, the recessed rectangular chamber also has a pair of horizontally inward flanges disposed on the long edges of the rectangular chamber to retain the memory card when it is inserted into the chamber.
According to another aspect of the invention, the base plate is supported by supporting poles on the printed circuit board in a manner the base plate is not in contact with the printed circuit board.
