Specific embodiment
Fig. 1 and Fig. 2 is please referred to, electronic device 10 includes upper cover 11 and the lower cover 12 separably attached with upper cover 11, electricity
Road plate 20, fixing piece 30 and protective cover 40.Circuit board 20 is set between upper cover 11 and lower cover 12, and fixing piece 30 is for connecting upper cover
11 and lower cover 12, protective cover 40 is set to the surface of upper cover 11 for covering fixing piece 30.
Please also refer to the mounting hole 14 that Fig. 3 to Fig. 5, upper cover 11 are equipped with recess 13 and penetrate through with recess 13, fixing piece
30 one end passes through mounting hole 14 to connect upper cover 11 and lower cover 12, and the other end of fixing piece 30 is placed in recess 13.
Protective cover 40 is set at recess 13 to cover fixing piece 30 comprising the outer 41 of annular structure and round pie knot
The inner disc 42 of structure.Inner disc 42 and outer 41 are made of metal material, and the thermal expansion coefficient of metal material that outer 41 uses is small
In the thermal expansion coefficient for the metal material that inner disc 42 uses.Inner disc 42 is nested in outer 41 and is interference fitted, and protective cover 40 is logical
It crosses outer 41 to be fixed at recess 13, and keeps the surface of protective cover 40 and the surface of upper cover 11 in the same plane.Make as a result,
User cannot easily disassemble protective cover 40, and protective cover 40 is just firmly fixed in upper cover 11 to cover fixing piece
30。
Circuit board 20 is equipped with perforation 21, signal conduction point 22 and the signal cut-off point 23 of corresponding mounting hole 14.Signal is led
Logical point 22 it is identical with the structure of signal cut-off point 23 and be arranged on circuit board 20 using perforate 21 center as center of circle shape
At two concentric circles circumference on, signal conduction point 22 and signal cut-off point 23 are designed on the circumference of each concentric circles.Its
In, the quantity of signal conduction point 22 is 1 on the circumference of each concentric circles, signal cut-off point 23 on the circumference of each concentric circles
Quantity be respectively 23 and 11.Signal conduction point 22 is electrical by other electronic components on circuit board 20 and circuit board 20
Connection.
30 penetrating mounting holes 14 of fixing piece are threadedly coupled mode with perforation 21 and connect upper cover 11 and lower cover 12.Fixing piece 30
On the second conduction element 32 and retaining ring 33 that are arranged with the first conduction element 31, are electrically connected with the first conduction element 31.First conduction element 31
And second conduction element 32 be flexible strip conductive sheet.It is designed on first conduction element 31 and the second conduction element 32 convex
The contact point 310 risen, is electrically connected with the signal conduction point 22 on two concentric circles on circuit board 20 respectively by contact point 310
So as to be electrically connected between signal conduction point 22.When the first conduction element 31 and the second conduction element 32 are connect with signal conduction point 22,
The first conduction element 31 and the second conduction element 32 and signal conduction point 22 be in first mode setting at this time, at this time signal conduction point 22 it
Between be electrically connected, electronic device 10 could work normally.Retaining ring 33 is for fixing the first conduction element 31 and the second conduction element 32 in solid
Determine on part 30.
When user dismantles electronic device 10 privately, that is, rotary mount 30 is needed so that upper cover 11 and lower cover 12 separate.
And protective cover 40 covers in fixing piece 30 and forms protection to fixing piece 30, user just can not easy removal electronic device 10.I.e.
Just user disassembles protective cover 40, and when rotary mount 30, fixing piece 30 drives the first conduction element 31 and second
The movement of conduction element 32 is with separating signal firing point 22, and the first conduction element 31 and the second conduction element 32 and firing point 22 are in second at this time
Mode setting.The feelings that the first conduction element 31 and the second conduction element 32 need to be electrically connected with signal conduction point 22 are not known in user
Under condition, it along with signal conduction point 22 is identical as 23 structure of signal cut-off point, and can not distinguish with appearance, thus just increase
The difficulty that re-assemblies.Such as user is when re-assemblying, just probably make contact point 310 and signal cut-off point 23 it
Between connect, connected between the first conduction element 31 and the second conduction element 32 and firing point 22 without making, to make the first conduction element
31 and second conduction element 32 be arranged with firing point 22 in second mode rather than first mode is arranged, to cause the mistake of electronic device
It mistakenly assembles.
In order to increase the difficulty for re-assemblying electronic device 10, need to make the quantity of signal cut-off point 23 to be greater than signal conduction
Point 22 quantity, such as in the present embodiment, on the circumference of two concentric circles the quantity of signal cut-off point 23 be respectively 23 and
11, the quantity of signal conduction point 22 is all 1.It is appreciated that the quantity of signal conduction point 22 and signal cut-off point 23 is unlimited
The particular number enumerated in present embodiment.
Electronic device 10 provided by the invention covers fixing piece 30 by the way that protective cover 40 is arranged on electronic device 10,
And the first conduction element 31 and the second conduction element connecting with the signal conduction point 22 on circuit board 20 are set on fixing piece 30
32, disassembly and the again difficulty of device electronic device 10 are increased, so that realizing prevents electronic device 10 random by user
The purpose of disassembly and assembling.
Those skilled in the art can also do other variations in spirit of that invention, certainly these according to the present invention spirit done
Variation, should all be included in invention which is intended to be protected.
