Abstract:
A peripheral provided with expansion connector attachable to a host and contains an interface connector (or a plug-socket unit) P1 to be connected to an interface connector (or a plug-socket unit) P0 from the host, a subsidiary I/O interface connector (or plug-socket unit) P2; a dedicated interface circuit C100 and an selection switch SL100 to conduct through said interface connector (or plug-socket unit) P1 either to said dedicated interface circuit C100 or the subsidiary I/O interface connector (or the plug-socket unit) P2, essentially comprised of:a housing HS100, made of plastic by molding injection, or cast alloy or metallic material or other materials to accommodate the dedicated circuit C100, the interface connector (or the plug-socket unit) P1, one or more than one set of subsidiary I/O interface connector (or the plug-socket unit) P2, and the selection switch SL100 for the interface connector (or the plug-socket unit) P1 to select to connect through the dedicated circuit C100, the interface connector (or the plug-socket unit) P1, or to the subsidiary I/O interface connector (or the plug-socket unit) P2; and a tennon, screw or magnet structure for the peripheral to be incorporated to the host; an interface connector (or the plug-socket unit) P1, for connection to the interface connector (or the plug-socket unit) P0 from the host; a dedicated interface C100, solid-state electronic circuit or electromechanical circuit such as a receiving circuit functioning as a receiver or other interface circuit dedicated to the peripheral, depending on the properties of the selected interface device; a subsidiary I/O interface connector (or the plug-socket unit) P2, to connect to other wired peripheral; and a selection switch SL100, relates a distributed type of selection switch comprised of electromechanical or solid-state circuit device to switch the interface connector (or the plug-socket) P1 to connect to the dedicated interface circuit C100 or to the subsidiary I/O interface connector (or the plug-socket unit) P2.
