Abstract: The present invention is to provide a circuit board in a housing and a plurality of contacts fixedly mounted on each of one end, the other end, and at least one side of the circuit board by surface mounting for forming a first external connector, a second external connector, and at least one internal connector wherein each of the first and the second external connectors is exposed to be ready for connection, at least one insertion slot is formed in the housing and, in response to inserting a memory card (e.g., T-Flash Card) into the insertion slot, a plurality of contacts of the internal connector are electrically connected to a plurality of conductive terminals of the memory card. Further, a shield is pivotally formed at the second external connector projected from the other end of the circuit board wherein the shield and the housing are assembled together to have a size dimensioned to comply with the specifications of a first type of memory card (e.g., Memory Stick Card or SD Card).
