Monitoring module of multi-card connector

A monitoring module of multi-card connector, comprising a electrically insulative housing and a monitoring module, wherein said housing comprising a base, two side arms respectively extending from said base at two sides in same direction, a receiving space defined between said two side arms above the base for receiving a memory card, and a sliding member mounted in said receiving space and having a sliding surface, characterized in that:

• said monitoring module comprises at least one common terminal and contact terminals being respectively fixed to said sliding member and said side arm nearby;
• said common terminal is integrally formed and includes a base having a penetrating hole at its center, a first pressing member continuously bent from one side of said base, a turning member bent from another side away from said first pressing member, an elastic arm extended from one side of said turning member, a second pressing member continuously bent from an end of said elastic arm and capable of moving reciprocally in said penetrating hole, and said first and second pressing members having a contact member at their ends respectively;
• thereby when a different memory card is inserted into said housing, said memory card moves said sliding member towards inward horizontally through said sliding surface, thereby said turning member of said common terminal, said contact member of said second pressing member and said contact member of said first pressing member are in contact with said corresponding contact terminals in sequence as to achieve the effects of concurrently detecting a circuit connection, a memory card installation, and a write-protect function.
