Referring to FIGS. 5 to 7, a detector for SD card according to the present invention is illustrated. The detector 3 is composed of a detection plate 31 and a control plate 32, which are inserted into the base recess 18 in a way of spacing apart from each other. The detecting plate 311 at two plate grooves thereof provides a detecting part 311 and a switch part 312 with both of them having a resilient bent respectively. The detecting part 311 at an end thereof is a free end 313. The control plate 32 has a plate groove 321 to receive the switch part 312 and extends a contact 322 to keep a clearance off the switch part 312. Besides, the detection plate 31 and the control plate 32 at the rear ends thereof are fixed ends 314, 323 for being soldered to the circuit board. The detection plate 31 and the control plate 32 keep spacing apart from each other as shown in FIG. 5 before the SD with a switch lock SW being inserted into the socket 17 c.
In case of the switch lock SW being in a state of locking, the contact part 322 and the detecting part 311 touch lateral walls of the SD card immediately as soon as the SD card is inserted into the slot socket 17 c. Once the SD card has been well placed in the slot socket 17 c, the contact part 322 touches the switch part 312 against the lateral walls of the SD card to ground both of the detection plate 31 and the control plate 32 and the detecting part 311 falls into a gap in front of the switch lock SW (as shown in FIG. 6). This means the SD card can process read only and it is not possible to perform the job of write.
1. A connection base for memory cards, comprising:
a base part, being an integrated casing made by way of injection molding, providing a longitudinal spacing wall and two transverse partitions between an upper wall and a lower wall and between two lateral walls of a rear wall thereof respectively based on a width and a height of each of different types memory cards such that a front side thereof is formed with four slot sockets, and each of the slot sockets being provided with a plurality of grooves or engaging recesses corresponding to the number of signal terminals of the respective memory card; and
four guide piece sections, being corresponding to the slot sockets respectively and each of the guide piece sections being located in and fixed to the corresponding one of the slot sockets and being composite of a plurality of metal guide pieces corresponding to the number of the grooves and the engaging recesses, the metal guide pieces being bent and inserted into the grooves and the engaging recesses, and each of the guide piece at an end thereof being a contact end received in the slot sockets and another end thereof being a connecting end;
whereby, once the base part is fixed to a circuit board and the respective guide piece at the connecting end thereof being soldered to the circuit board, each of the signal terminals can touch the contact end of the respective guide piece as soon as the different types memory cards are inserted into the respective corresponding slot socket, and the memory cards can be read out or written in data.
2. The connection base for memory cards according to claim 1, wherein a first one and a second one of the slot sockets are adjacent to the circuit board and can be inserted with and connect with a smart media card (SM), a secure digital card (SD) and a multimedia card (MMC) respectively.
a detecting plate, being a bent metal piece and inserted into the base recess, providing two plate grooves extending a resilient bent detecting part and a bent resilient bent switch part, the detecting plate at an end thereof being a free end and at another end thereof being fixed to the circuit board by way of soldering; and
a control plate, being a bent metal piece and inserting into the base recess, keeping spacing apart from the detecting plate, having a plate groove to receive a switch part and extending a contact part to keep a clearance off the switch part, and having a rear end being soldered to the circuit board;
whereby, once the SD card is inserted into the corresponding slot socket, the contact part is pressed by the lateral walls of the SD card to touch the switch part and to form grounding and the detecting piece at the free end thereof contacts with the end connecting piece selectively in accordance with a switch lock arranged on the SD such that an open circuit or grounding can be formed to detect the switch lock being in a state of locking or unlocking.
7. The connection base for memory cards according to claim 1, further comprises another detector disposed a card groove formed at the lateral walls of the slot socket for the SM card, and said another detector comprises:
a sense piece, being a bent metal piece and inserted into the card groove, having a frame groove and a bent sense part being disposed in the frame groove with a slant extending free end and another end being fixed to the circuit board by way of soldering;
an extension piece, being a bent metal piece and being inserted into the card groove, keeping spacing apart from the sense part, providing a contact part being disposed corresponding to the sense part, and at a rear end thereof being fixed to the circuit board by way of soldering;
whereby, once the SM card is inserted into the corresponding slot socket, the free end is pressed and the sense piece displaces to touch the contact part such that a grounding can be formed so as to detect if the SM card is in a state of being located or not.
8. The connection base for memory cards according to claim 1, wherein each guide piece of the guide piece sections is bent as a letter “J” with a contact part thereof being disposed at an upper side thereof such that a facial side of the SD card (the side providing a label) is in accordance with a facial side of the SM card, the CF card or the MS card.
a slot socket, providing a plurality of engaging recesses corresponding to the number of signal terminals on a SD card for a plurality of metal guide pieces being inserted and located, receiving a contact part at an end of each of the guide pieces and each of the guide pieces at another end thereof being a connection end fixed to a circuit board by way of soldering, and providing a base groove formed by lateral walls thereof, and a front side thereof communicating with an end connecting piece;
10. The connection base for memory cards according to claim 9, wherein each guide piece of the guide piece sections is bent as a capital “J” with a contact part thereof being disposed at an upper side thereof.
