Description
Technical field
What the utility model suppressed that concertina type mobile electron storer relates to is a kind of USB interface mobile electron flash memory, is called for short flash memories.
Background technology
At present commercially available flash memory is in order to protect USB interface; usually adopt block to come encapsulation in the USB interface outside; must pull out during use, and after pulling out, block is lost easily; cause USB interface to be effectively protected; the block is often extracted in addition, suit, can cause wearing and tearing to USB interface, loose contact when causing USB interface to be connected with main frame; influence electric property, bring inconvenience to operation.In addition, the split of body and block design influences the good looking appearance of flash memory.
Summary of the invention
The purpose of this utility model is to provide a kind of concertina type mobile electron storer that suppresses at above-mentioned weak point; suppress concertina type mobile electron storer and be provided with ejecting mechanism; make product USB interface retraction product shell inside when not using; be used to protect USB interface; as long as one connect gently, USB interface ejects, and is easy to use during use; appearance design is not because of blocking a shot novel and beautiful.
Suppressing concertina type mobile electron storer takes following scheme to realize: suppress concertina type mobile electron memory construction and comprise housing, button, USB interface, the electronic memory circuit plate, the circuit board stationary housing, the lanyard lid, housing is by upper shell, lower house is formed, key device is on upper shell, upper shell is provided with locating groove, be provided with decorative panel in the upper shell outside, device has the circuit board stationary housing in the housing, the circuit board stationary housing is by the fixing upper casing of circuit board, circuit board fixedly lower casing constitutes, the electronic memory circuit plate is fixed in the circuit board stationary housing, circuit board fixedly upper casing is provided with locator card and spring fixed column, device has spring on the spring fixed column, and USB interface is welded on the electronic memory circuit plate.
Principle of work: during use, press the circuit board stationary housing, the USB interface that is weldingly fixed on the circuit board is stretched out in housing, in this process, be fixed on the compression that is squeezed of spring on the circuit board stationary housing, when USB interface is exposed the housing sufficient size and is connected with main frame, be arranged on circuit board fixedly the limited bayonet card on the upper casing be inserted in the locating groove on the upper shell, can resilience after making USB interface stretch out housing.Press the button that is fixed on the upper shell after using end, make the bayonet socket on the limited bayonet disengaging upper shell, enter in the housing because the spring force effect is shunk USB interface and circuit board, the protection USB interface is not damaged.
Suppress concertina type mobile electron reservoir designs rationally, compact conformation, good looking appearance, volume be little, easy to carry; because electronic memory is provided with the ejecting mechanism that is made of locator card, locating groove, spring; make the product automatic retraction product shell of USB interface inside when not using be used to protect USB interface not to be damaged; need only during use and one press gently; USB interface ejects automatically, and is extremely easy to use.The utility model suppresses concertina type mobile electron storer can be widely used in the alternative floppy disk in mobile storage field, the storage data security is reliable, low in energy consumption, easy to connect with computer, shockproof, moistureproof, antiviral performance is good, and can carry out safety encipher to data and handle.
