Abstract
A common socket device for memory cards is a common inserted base with an upper cover to offer a common space for receive a smart media card, a multimedia card, and a secure digital memory card. The common base may be inserted by two or three memory cards without a need of providing two or three kinds of different socket device. Therefore, contact points in the common socket device is reduced substantially, a less volume of the common socket device is obtained comparing to the gross volume of two or three conventional socket devices, and it enhance the convenience for the user.
Claims15
A common socket device for memory cards, comprising:
- base with a rear side;
- an upper cover with a rear side, being joined to the base, and being provided with a projection section;
- and
- a conductive part, being provided on the base and/or inside the upper cover respectively for matching with contact pieces on the respective memory card;
- wherein, a first receiving slot and a second receiving slot are formed in the common socket device and a common section is between said two receiving slots respectively and wherein said base has a lower recession part to make interior of the common socket device form a third receiving slot to share the common section for the first and the second receiving slots.
2 more elements
A common socket device for a plurality of different memory cards, comprising:
- a base with a rear side;
- an upper cover with a rear side joined to the base the upper cover including a projection section;
- and
- a conductive part provided inside one of the base and the upper cover located to match with contact pieces on a plurality of different memory cards;
- a microprocessor, connecting joining points of each sensor switch on the common socket device;
- a first interface connector for data of a smart media card;
- a second interface connector for data of a multimedia card/secure digital memory card;
- a first switch with two ends, an end of said two ends connecting with said interface connector on the smart media card;
- a second switch with two ends, one of said two ends connecting with said interface connector on the multimedia card/secure digital memory card;
- and
- a conductive part at a base on the common socket device, connecting the other end of said first switch and the other end of said second switch respectively;
- wherein the base and upper cover form a single receiving slot having at least first and second receiving slot portions with a common section between said at least first and second receiving slot portions so as to accommodate a plurality of different memory cards therein;
- and
- wherein said upper cover is provided with sensor switches;
- whereby, the microprocessor may sense reaction signal from said sensor switch to determine a control of first switch via the first connector or a control of second switch via the second connector while the smart media card or a multimedia card/secure digital memory card is inserted into the common socket device such that the conductive part can be connected so as to connect the smart media card or multimedia card/secure digital card.

A common socket device for a plurality of different memory cards, comprising:
- a base with a rear side;
- an upper cover with a rear side joined to the base, the upper cover including a projection section;
- and
- a conductive part provided inside one of the base and the upper cover located to match with contact pieces on a plurality of different memory cards;
- a microprocessor, connecting joining points of each sensor switch on the common socket device;
- a first interface connector for data of a smart media card;
- a second interface connector for data of a multimedia card/secure digital memory card;
- a conductive part at a base on the common socket device, connecting with said first switch and said second switch respectively;
- and
- a plurality of connecting pins at an upper cover of the common socket device, connecting said two connectors either;
- wherein the base and upper cover form a single receiving slot having at least first and second receiving slot portions with a common section between said at least first and second receiving slot portions so as to accommodate a plurality of different memory cards therein;
- and
- wherein said projection section on the upper cover at an internal side thereof further comprises a plurality of connecting pins with first ends thereof extending out of the rear side of the upper cover and second ends thereof elastically bent upward;
- whereby, once a smart media card or a multimedia card/secure digital memory card is inserted into the common socket device, the microprocessor may sense reaction signals from the respective sensor switch to identify the smart media card or to read directly if the multimedia card/secure digital card is inserted and then determine a data reading and writing in the smart media card via the first connector or in the multimedia card/secure digital memory card via the second connector.
