Abstract
The utility model provides a memory card connector provided with a snap-fixing device. The snap-fixing device is equipped on a rotating-sliding memory card connector to limit horizontal displacement of the metal shell of the connector, thus the metal shell cannot move to a position where it can rotate. The snap-fixing device consists of an elastic clamp of the metal shell and a fixing sheet arranged on an insulating rubber core. The elastic clamp is provided with a protruding part and the fixing sheet is provided with a positioning part at the correspondent position. When the protruding part moved horizontally over the positioning part, its movement is limited. The metal shell can be maintained in the positioning part under a certain force range to ensure connecting stability of the memory card.
