Area become big and open wide the receiving space 322, fastener 4 can enter the receiving space 322 through the cut-off mouth 331.
When the barriers 33 are not by external force, the barriers 33 close the receiving space 322, and the area of the cut-off mouth 331 is very
Small or area is zero, and the barriers 33 can prevent fastener 4 from departing from the receiving space 322.
The cut-off mouth 331 can be very narrow and small gap, or breach.For example, the cut-off mouth 331 is transversal
Face (on the direction of the circuit board 2) is shaped as inverted triangle, and the bottom surface of the cut-off mouth 331 is away from the fastening
Hole 321, the summit of the cut-off mouth 331 is towards the fastener hole 321.When external force is acted on the cut-off mouth 331, Neng Goushun
Expand the area of the cut-off mouth 331 sharply.
As shown in fig. 7, as a kind of alternative embodiment, the barriers 33 are rotatablely connected the fixation by rotating shaft 332
Portion 32, to close or open wide the receiving space 322.When needing to install the fastener 4, the barriers 33 are rotated to open wide
The receiving space 322, the fastener 4 get enter into the receiving space 322.After the installation of fastener 4, rotate
The fastener 4 is to close the receiving space 322, to prevent the fastener 4 from departing from the receiving space 322.The resistance
Spacing body 33 can substantially plate-like or laminated structure.
As shown in figure 8, as a kind of alternative embodiment, the fixed part 32 is provided with chute 324, and the barriers 33 pass through
The chute 324 is slidably connected the fixed part 32, to close or open wide the receiving space 322.Need that the fastening is installed
During part 4, the barriers 33 are slided to open wide the receiving space 322, the fastener 4 gets enter into the receiving space
322.After the installation of fastener 4, the fastener 4 is slided to close the receiving space 322, to prevent the fastening
Part 4 departs from the receiving space 322.The barriers 33 can substantially plate-like or laminated structure.
Optionally, the barriers 33 are provided with limited block 333, and the limited block 333 is contained in the receiving space
322.The limited block 333 is used for when supporting the wall of the receiving space 322, limits the barriers 33 and continues to slide,
To prevent the barriers 33 from departing from the fixed part 32.
It should be understood that in embodiments of the present invention, can be with complete when the barriers 33 close the receiving space 322
The totally-enclosed receiving space 322, can also leave small gap/small gap, as long as the fastener 4 can be stopped to prevent
State fastener 4 and depart from the receiving space 322.When the barriers 33 open wide the receiving space 322, it can open completely
The receiving space 322 is opened, can also partly open wide the receiving space 322, as long as allowing the fastener 4 to enter the receipts
Hold space 322.
Also referring to Fig. 3 to Fig. 8, as a kind of alternative embodiment, the gland portion 31 and the one of fixed part 32
Shaping, to reduce the technology difficulty and cost of the fixed support 3.
Optionally, as shown in Fig. 3, Fig. 5, Fig. 7 and Fig. 8, the gland portion 31 is with the fixed part 32 by being molded into
Type technique is integrally formed.
Optionally, as shown in fig. 6, the gland portion 31 passes through metal sheet bending technique or punching press with the fixed part 32
Technique is integrally formed.It is smaller (perpendicular to the direction of circuit board 2) using the thickness in the gland portion 31 of metal sheet material
And intensity is higher, be advantageous to reduce the volume of the fixed support 3, so as to be advantageous to the lightening of the mobile terminal 100.
Also referring to Fig. 3, Fig. 4 and Fig. 6 to Fig. 8, as a kind of alternative embodiment, perpendicular to the circuit board 2
Direction on, the depth H 1 of the receiving space 322 and the depth H 2 of the fastener hole 321 and (H1+H2) be less than it is described tight
The length L of firmware 4.When the fastener 4 loosens, due to the depth H 1 and the fastener hole 321 of the receiving space 322
Depth H 2 and the length L less than the fastener 4, therefore can to support the fastener 4 tight to prevent for the barriers 33
Firmware 4 continues to loosen, and the fastener 4 still has part in the mounting hole 21, so as to be still able to realize described in connection
The effect of fixed part 32 and the circuit board 2.
Certainly, as shown in figure 5, in other embodiments, the depth H 1 of the receiving space 322 and the fastener hole
321 depth H 2 and can also be more than or equal to the fastener 4 length L.After the loosening of fastener 4 is dropped, it can be received
Hold in the receiving space 322, without departing from the receiving space 322.
The embodiment of the present invention is described in detail above, specific case used herein to the principle of the present invention and
Embodiment is set forth, and the explanation of above example is only intended to help the method and its core concept for understanding the present invention；
Meanwhile for those of ordinary skill in the art, according to the thought of the present invention, can in specific embodiments and applications
There is change part, in summary, this specification content should not be construed as limiting the invention.
