Abstract: A signal adapter for memory card serving as a signal bridge for transfer data between a memory card and a computer, etc, mainly comprise a base plate and an upper and a lower board, which enclose a plurality of overlapped slot space for receiving memory cards in different measurements. The signal adapter may be transplanting to a generic card reader to become a low-cost universal card reader for reading various memory cards.

Abstract: The present invention discloses a memory card adapter structure, comprising a main body and a baseboard. The main body is overlapped on the baseboard and has a socket on one end. The socket can host different types of memory cards. There are multi PIN receptacles in the socket. On the baseboard, there is a containing hole against the PIN receptacles on the main body. Furthermore, there is a connector at one side of the baseboard. When the main body is coupled with the baseboard, the PIN receptacles will enter into the containing hole, and then the PINs in the receptacle will contact with the baseboard to form a closed circuit. In this way, different memory cards can be connected to the adapter to transfer signals and data at different times.

Abstract: A coupling assembly for plugging and conductively jointing an interface card with an external circuit board comprises a plastic housing including a ground piece, a plurality of conductive pins, and an adapter circuit board, wherein the ground piece and the plurality of conductive pins are disposed in the adapter circuit board while a plurality of outward connecting pins is disposed under the adapter circuit board for conductively jointing the ground piece and the conductive pins with the outward connecting pins.

Abstract: An electric connector structure is disclosed. The frame body thereof is integrally formed with a vertical plate and a horizontal plate which are connected with each other, and the aforementioned connector with a plurality of terminal inserting holes is formed integrally on the horizontal plate, place of the connection of horizontal plate and the vertical plate is installed with connector mounting hole, the connector mounting hole is used to mount the second connector. A notch for mounting the first connector and cause the terminal pins on the first connector is inserted into these inserting holes. Thus, the error induced from assembly is prevented.
