Abstract:
1. A structure for a socket of a multi-card reader, wherein the socket of the multi-card reader supports the insertion of diverse memory cards with distinct specifications, and which at least includes an upper cover, a socket body, multiple connecting terminals and read-protection devices, wherein: the upper cover covers and is in combination with the socket body, and an elastic part is provided atop the upper cover to interlock a resist part and thus control a free rotation of the read-protection device; connecting terminals are provided inside the socket body, while at corresponding positions on both side walls of the socket body axle bases are provided for pivoting a slider; the multiple connecting terminals are made from metallically conductive materials for contacting a memory card and thus for delivering information and power; the read-protection devices include: the slider, which uses one end as an axle to constrain the insertion of the memory card, is provided with a concave part at the bottom of the slider while bumps are formed at both sides of the slider, and resist slots are provided at the axle part of the slider to support the control applied by the resist part of the upper cover, and a recovery device is provided at the axle part; the recovery device uses the socket body as a bearing point to provide energy for recovering the slider; the read-protection devices are pivotally installed in the socket of the card reader, and utilize different thicknesses of memory cards with distinct specifications to push the elastic part of the upper cover to enable the slider to perform an action of release or resist, thus preventing mis-contact or initialization caused by inserting the memory card with distinct specification.
