Abstract: A card recognition method is disclosed to provide a Micro SD adapter, which has a common insertion slot for the insertion of a M2 memory card or a Micro SD memory card, and a microprocessor with a built-in software program for detecting the potential signal of the inserted memory card and switching on or off the Micro SD memory card signal transmission path or the M2 memory card signal transmission path subject to the detection result, so that an external electronic device to which the Micro SD adapter is electrically connected can communicate with the memory card in the common insertion slot for signal transmission.

Abstract: A card reader is disclosed to include a body, which has a USB plug at one end and an insertion slot at the other end for the insertion of an electronic card, an adapter, which is receivable in a top accommodation open chamber of the body and has a Micro-USB plug and a Mini-USB plug at two opposite sides, and a transmission line, which is receivable with the adapter in the top accommodation open chamber of the body and has a first connection terminal electrically connected to a circuit board inside the body and a second connection terminal inserted into a base of the adapter and electrically connected with the Micro-USB plug and the Mini-USB plug. An electronic apparatus to which the USB plug or the Micro-USB plug or Mini-USB plug of the adapter is connected can fetch data from an electronic card that is inserted into the insertion slot.

Abstract: A USB connector type memory card adapter is disclosed to include a metal shield covered with a cover shell having a memory card insertion hole and insertable into a USB jack of an electronic apparatus, a USB connector unit mounted inside the metal shield and electrically connectable to the USB jack into which the metal shield is inserted, and a memory card module longitudinally connected to the rear end of the USB connector unit in a flush manner inside the metal shield and electrically connected to the USB connector unit for receiving the inserted memory card and electrically connecting the inserted memory card to the USB connector unit.

Abstract: A mobile memory card adapter includes a housing having an insertion hole, a circuit board that is accommodated in the housing and has a fixed connection interface extending out of one end of the housing and a movable adapter interface connected thereto with a cable and extendable to the outside of the housing at a distance, and multiple conducting terminal sets each having an insulative block detachably fastened to the circuit board and multiple metal conducting terminals kept in contact with respective conducting contacts of the circuit board and suspending in the insertion hole of the housing for the contact of a corresponding memory card that is selected by the user and inserted into the insertion hole to let the inserted memory card be electrically connected to an external electronic device through the fixed connection interface or the movable adapter interface.

Abstract: A conducting terminal mounting structure is disclosed to include a housing having an accommodation chamber and an insertion hole, a circuit board, which is mounted in the accommodation chamber inside the housing and has multiple electric contacts and an adapter interface electrically connectable to an external electronic apparatus, and a terminal set, which comprises multiple conducting terminals and an electrically insulative locating block formed integral with the conducting terminals and fastened to the circuit board to hold the conducting terminals in connection with the circuit board electrically.
