Flash memory device with retractable plug

A flash memory device, comprising:

• a movable housing defining a receiving cavity;
• a control board having a circuit board and a plug connecting with the circuit board, the circuit board retained in the receiving cavity, the plug extending out of the receiving cavity;
• an outer shield defining an opening at one end thereof;
• and
• a sleeve movably ringed on one side of the movable housing and enclosing the plug;
• wherein the movable housing is movably received in the outer shield, the movable housing having an elastic section, the elastic section comprises a button extending out of the outer shield which can push the movable housing moving relative to the outer shield;
• wherein the sleeve is moved out of the opening firstly when pushing the button forwardly, the plug is moved out of the sleeve secondly as the sleeve moving out of the opening.

A flash memory device comprising:

• an outer shield defining an opening at a front end;
• a housing enclosed in the outer shield and being movable relative to the outer shield in a front-to-back direction;
• a connector retained to a front end of the housing;
• and
• a sleeve located around the opening and movable relative to the shield in said front-to-back direction, said sleeve essentially surrounding the connector and being surrounded by the shield;
• wherein
• the sleeve is movable relative to the shield along said front-to-back direction with a first distance, the housing is movable relative to the sleeve along said front-t0-back direction with a second distance, and the housing is movable relative to the shield along said front-to-back direction with a third distance under a condition that the third distance is essentially equal to a sum of said first distance and said second distance.
