Abstract
An integrative memory card adapter capable of accommodating a compact flash card, a multi-media card, a digital card and a smart media card. By positioning contact pins and entrance slots in various locations on the memory card adapter according to the specifications and input/output contact positions of various memory cards, all four types of memory card are accommodated. The memory cards can be accommodated because the input/output contact points of each memory card are in contact with corresponding contact pins inside the slots. The contact pins are in turn wired to a printed circuit board with external connection.
Claims20
A memory card adapter, comprising:
- a printed circuit board;
- a contact pin header on the printed circuit board, wherein the contact pin header connects electrically with the printed circuit board and has a plurality of first contact pins;
- and
- a frame having a card insertion terminal and an external connection terminal, wherein the frame comprises an upper frame and a lower frame that enclose the printed circuit board and the contact pin header, wherein an interior of the upper frame contains a plurality of second contact pins laid on the upper frame and electrically connected with the printed circuit board, and an interior of the lower frame contains a plurality of third contact pins laid on the lower frame and electrically connected with the printed circuit board, so that a memory card inserted in the memory card adapter through the card insertion terminal connects either the first, second, or third contact pins.
A memory card adapter, comprising:
- a printed circuit board;
- a contact pin header on the printed circuit board, wherein the contact pin header connects electrically with the printed circuit board and has a plurality of first contact pins;
- and
- a frame having a card insertion terminal and an external connection terminal, wherein the frame encloses the printed circuit board and the contact pin header, and an interior of the frame has a plurality of second contact pins and a plurality of third contact pins, wherein the second contact pins and the third contact pins are respectively laid on spaced-apart locations of the frame and electrically connected with the printed circuit board, so that a memory card inserted in the memory card adapter through the card insertion terminal electrically connects either the first, second, or third contact pins.
A memory card adapter, comprising:
- a printed circuit board;
- a contact pin header arranged on the printed circuit board, wherein the contact pin header connects electrically with the printed circuit board and has a plurality of first contact pins to connect a first memory card;
- and
- a frame structure including an upper frame, a lower frame, and a movable door that enclose the printed circuit board and the contact pin header, wherein the upper and lower frames and the movable door form a card insertion terminal, wherein an interior of the upper frame contains a plurality of second contact pins laid on the upper frame and electrically connected with the printed circuit board, and an interior of the lower frame contains a plurality of third contact pins laid on the lower frame and electrically connected with the printed circuit board, so that various types of memory cards can be inserted in different manners through the card insertion terminal to connect either the first, second, or third contact pins.
