Described first, second housing 2,3 is provided with the rib 25,35 of mutual fastening.Wherein, second housing 3 comprises that matrix part 31 reaches from the vertically extending kink 32 of matrix part 31 1 ends, and described kink 32 is provided with rectangular through-hole 33 and passes for USB plug 41.
During assembling, the location division 61 of elastic component 6 is fixed on base 1 rib 14 recesses and relatively base 1 do not have relative motion (as shown in figure 12).Utilize the elasticity of simply supported beam 28 that it is installed in the receiving space 13 of base 1, described simply supported beam 28 is positioned at the below of first, second locating piece 121,122 and is limited to move upward.The holding part 63 of described elastic component 6 passes groove 27 and extends upwardly in the receiving space 13 of base 1.The latch part 76 of retainer 71 is socketed in the through hole 723 of protective door 72 curled portion 722 to form a door member 7.The elongated portion 74 of described retainer 71 is pressed in the slit 23 along the guiding face 241 of boss 24, because pressure section 242 broads of described boss 24, described pressure section 242 compresses with the elongated portion 74 of retainer 71, comes off to prevent retainer 71.Simultaneously, the installation portion 73 and first housing, 2 protuberances 291 of described door member 7 offset (as shown in Figure 9), can prevent that also retainer 71 from coming off.Then, locating part 5 is held on the both sides of circuit board 4 and is installed on first housing 2, the main part 721 of described protective door 72 covers USB plug 41, and bending edge 724 coats USB plug 41 sides (as shown in Figure 2), and described holding part 63 is snapped in first fixing hole 511 of locating part 5.At last, the rib 25,35 that fastens mutually by first, second housing 2,3 is held in second housing 3 on first housing 2, to form an integral body.Described first, second housing 2,3 base 1 relatively slides to expose USB plug 41 or USB plug 41 is withdrawn into flash memory device 100 inside.
During use, the first step, as shown in figure 13, earlier first, second housing 2,3 is pulled back, to expose USB plug 41, in this process, the fore-end 261 of described first housing, 2 arc-shaped inner surfaces 26 compresses with the holding part 63 of elastic component 6, the extension 62 of elastic component 6 outwards moves, and it is outwards mobile to drive holding part 63, forms the trend that breaks away from first fixing hole 511 gradually.When first, second housing 2,3 pulls back when exposing USB plug 41 fully, first end face 522 of described locating part 5 just in time supports on second locating piece 122 of base 1, cause first, second housing 2,3 not move backward again, at this moment, the holding part 63 of elastic component 6 breaks away from first fixing hole 511, and then moves in the slide rail 521.
Second step, as shown in figure 14, first, second housing 2,3 is promoted forward, the circuit board 4 that described first, second housing 2,3 drives in it moves forward together, the holding part 63 of described elastic component 6 moves in slide rail 521, when first, second housing 2,3 is pushed forward to the precalculated position, second end face 523 of described locating part 5 just in time supports on first locating piece 121 of base 1, simultaneously, the holding part 63 of described elastic component 6 moves in second fixing hole 512 in slide rail 521, and then locating part 5 snap closes are lived.
After flash memory device 100 is finished using, at first, first, second housing 2,3 is continued to push away forward, the holding part 63 of elastic component 6 is expanded outwardly under the compressing of first housing, 2 arc-shaped inner surfaces, 26 rear end parts 263, and then holding part 63 is come back in the slide rail 521 in second fixing hole 512, at this moment, because second end face 523 of locating part 5 supports on first locating piece 121 of base 1, therefore, circuit board 4 can not move.Along with moving of first, second housing 2,3, USB plug 41 is withdrawn in the protective door 72.
Secondly, first, second housing 2,3 is moved backward, the holding part 63 that makes elastic component 6 is in slide rail 521 comes back to first fixing hole 511 of locating part 5 (as shown in Figure 1).
The inclined-plane 514 of described locating part 5 pars intermedias 513 can make flash memory device 100 be in unused state, when being subjected to greater impact because of dropping because of carelessness, holding part 63 can overcome less resistance and move to rapidly in the slide rail 521 from first fixing hole 511, and then avoids holding part 63 to deform, lost efficacy because of being subjected to big impulse force.
