Description
Technical field
The present invention relates to mobile technical field of memory, and in particular to one kind is anti-to lose USB flash disk.
Background technology
USB flash disk, full name USB flash drive are that a kind of miniature high power capacity movement using USB interface without phisical drive is deposited
Product is stored up, can be connect with computer by USB interface.
In general, USB flash disk includes USB plug, pcb board and shell, master control movement is integrated on pcb board.Pcb board is located in shell
Portion is simultaneously mutually fixedly connected with USB plug, and for USB plug for being plugged with the USB jack on computer, USB plug is inserted into USB jack
Later, the data information stored in readable in computer movement, can also be written data information into movement.Due to USB plug and PCB
To be fixedly connected between plate, so, after USB flash disk is collided by the external world it is easy that USB plug is made to bend with movement connection,
It is even broken off, results in damaging when bending serious or after being broken off and can not be further continued for using.
Invention content
The purpose of the present invention is to provide one kind to prevent losing USB flash disk, is collided to solve the existing USB flash disk inserted on computers
After be easy to happen the problem of losing.
To achieve the above object, the technical scheme is that：

The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
Embodiment 1
One kind is anti-to lose USB flash disk, as shown in Figure 1, including shell 1 and lid 2, in conjunction with Fig. 2, one end of shell 1 is fixedly connected
There is USB plug 3, in conjunction with Fig. 3, plug is plugged with lid 2.
As shown in figure 4, shell 1 is internally provided with pcb board 4, integrated circuit and other electric elements, PCB are used on pcb board 4
Plate 4 is fixedly connected with 3 phase of USB plug.USB plug 3 is inserted into after the USB jack of computer, can be read the data stored in USB flash disk or
Data are written into USB flash disk.
USB plug 3 is detachable, including front end plug 31 and rear end socket 32, and front end plug 31 is used for and computer
USB jack plug.Rear end socket 32 makes front end plug 31 be connected with pcb board 4 for 31 grafting of front end plug.
As shown in figure 5, front end plug 31 is fixedly connected with boss 311 close to one end of rear end socket 32, boss 311 has
Drafting angle, the smaller one end of boss 311 are directed away from the direction of front end plug 31.In conjunction with Fig. 6, rear end socket 32 leans on front end
One end of plug 31 offers the cavity 321 for 311 grafting of boss, the drafting angle of the drafting angle and boss 311 of cavity 321
It is identical, boss 311 be inserted into cavity 321 after, the outer wall of boss 311 can closely be abutted with cavity 321, can limit front end plug 31 and
Rear end socket 32 is along the direction relative motion perpendicular to 311 longitudinal axis of boss.The cross section of boss 311 is ellipse, can be limited
Relative rotation between front end plug 31 and rear end socket 32 processed.
As shown in fig. 7, front end plug 31 offers front end fixing groove 312 close to one end of rear end socket 32, front end is fixed
Front end magnet 313 is fixedly connected in slot 312；In conjunction with Fig. 6, rear end socket 32 offers rear end by one end of front end plug 31
Fixing groove 322 is fixedly connected with rear end magnet 323 in rear end fixing groove 322, after boss 311 is inserted into cavity 321, front end magnet
313 can attract each other with rear end magnet 323, constitute absorption disconnecting prevention structure, front end plug 31 is made to be kept steadily with rear end plug
Split limits between front end plug 31 and rear end socket 32 along the direction relative motion being located remotely from each other.
As shown in figure 5, front end plug 31 is fixedly connected with raised line 314 close to one end of rear end socket 32, in conjunction with Fig. 6, after
End socket 32 opens up fluted 324 by one end of front end plug 31, and boss 311 is inserted into after cavity 321, raised line 314 with it is recessed
Slot 324 plugs, and can further strengthen front end plug 31 with rear end socket 32 along the company perpendicular to 311 central axial direction of boss

The direction of front end plug 31.Groove 324 is the structure with 314 complementation of raised line, i.e., is also arc and has drafting angle, raised line
314 are inserted into after groove 324, and the outer wall of raised line 314 can closely be abutted with 324 inner wall of groove.
As shown in figure 8, after front end plug 31 is inserted into the USB jack of computer, shell 1 is hit by side surface direction
When power (in such as Fig. 8, arrow direction represented by f is the Impact direction of shell 1), rear end socket 32 and front end plug 31 it
Between there is the trend of separation, in conjunction with Fig. 9, after impact force reaches some strength, between rear end socket 32 and front end plug 31 point
From active force be more than attraction between front end magnet 313 and rear end magnet 323, shell 1 is deflected towards Impact direction, in rotation
The heart is the one side that front end plug 31 splices with 32 phase of rear end socket and the side for being located remotely from 1 stress surface of shell, due to boss
311, cavity 321, raised line 314 and groove 324 all have drafting angle, and boss 311 will not be mutually dry with 321 inner wall of cavity
It relates to, figure item will not be interfered with 324 inner wall of groove.
Active force numerical value when the active force being subject to makes to be separated from each other between front end plug 31 and rear end socket 32 is referred to as curved
Folding power threshold values, i.e., after hitting the active force generated more than folding force threshold values, between front end plug 31 and rear end socket 32 i.e. certainly
Dynamic to be separated from each other, without bending or being broken off damage, boss 311, which is reinserted after cavity 321, can restore intact.
Since the cross section of boss 311 is ellipse, shell 1 is hit and hit from the different directions of 1 side of shell
Hit generation active force be more than folding force threshold values after so that front end plug 31 is separated from each other with rear end socket 32.
In conjunction with Figure 10, AB indicates that the draft side of boss 311 or cavity 321, AC indicate the height of boss 311, use h in Figure 10
It indicates, O indicates that the rotation center of boss 311, A indicate that 311 end face of the boss point farthest apart from rotation center, AO indicate boss
The 311 end faces distance farthest apart from rotation center, is indicated with s, and θ indicates draft angle.If angle OAB is less than 90 degree, can occur
Interference is limiting condition when AB and AO is perpendicular.So narration is unfolded by taking the vertical AO of AB as an example, angle AOB is also θ, then draft angle
Degree, boss 311 are highly and the relationship between 311 rotation center position of boss is：H=s*sin (θ).When angle, θ and distance s
After determination, as long as meeting h is less than or equal to s*sin (θ), after height h and distance s is determined, it is more than as long as meeting θ
Or it is equal to arcsin (h/s), after height h and angle, θ determination, as long as meeting s i.e. more than or equal to h/s*sin (θ)
It can.
