Description
Technical field
The utility model relates to a kind of circuit board fixing mechanism, and particularly a kind of being applied to is fixed in circuit board fixing mechanism on the loading plate with circuit board.
Background technology
Along with progress, the electronic product of science and technology is that single circuit board can't satisfy the demand of electronic product multifunction towards the trend of multifunction development, under the popularization and application of server and PC.So, except original circuit board, also additionally integrated circuit plate, expansion board etc. to promote the functional of product.Simultaneously, when promoting the electronic product function, it is complicated that the required technique for fixing of electronic product internal structure relatively more is tending towards.Hence one can see that, and how easy-disassembling-assembling fixed mechanism is provided, promotes and manufacture efficient, will be a following big problem that is faced.
Available circuit plate technique for fixing adopts such as lock members such as screws, in the bolt-lock mode circuit board is fixed on the loading plate of electronic products such as server or host computer.Yet the shortcoming of this kind technique for fixing is that the operating personnel need use a large amount of screws, and must carry out the assembling operation of screw bolt-lock with aids such as for example screwdrivers.
In addition, when needs dismounting, replacing circuit board, also similarly need re-use screwdriver and disassemble operation, very consuming time.Therefore, it is low that existing technique for fixing can cause the efficient of assembling, maintenance activity of circuit board.In order to improve the efficient of aforementioned fixation technology, there is the people to propose to need not to use the circuit board fixing mechanism person of screw in the prior art.
See also Figure 1A, on loading plate 11, be installed with a plurality of support columns 12 and the flexible stop part 13 of a tool in the prior art, and in circuit board 14 be provided with location division 15 with by stop section 141.By the fastening of support column 12, circuit board 14 is positioned on the loading plate 11 with location division 15; One end of this stop part 13 is provided with operating portion 131, and with stop section 132 be connected on the circuit board 14 by stop section 141, and circuit board 14 is fixed on the loading plate 11, be described in detail as follows at this:
Existing fixed mechanism is positioned at circuit board 14 on the loading plate 11 by positioning unit, and this positioning unit is made up of a plurality of location divisions 15 of being located at a plurality of support columns 12 on the loading plate 11 and be located on this circuit board 14.
Wherein, this support column 12 is fixedly arranged on loading plate 21, has foundation 121, is formed at the neck post 122 of this foundation top and is formed at the headpin 123 of this neck post top.
This location division 15 is made up of cover hand-hole 151 and the location hole 152 that is communicated in this cover hand-hole 151, and this overlaps the radius of the radius of hand-hole 151 greater than this location hole 152.
The maximum radius of this headpin 123 is slightly less than the radius of this cover hand-hole 151, so that pass this cover hand-hole 151; The height of this neck post 122 is to be the radius that cooperates this location hole 152 corresponding to the thickness of this circuit board 14 and radius, to be positioned in this location hole 152; 121 on this foundation is in order to support this circuit board 14, so that keep suitable distance between circuit board 14 and the loading plate 11.
See also Figure 1B and Fig. 1 C, the fixed form of this fixed mechanism is to apply the operating portion 131 of strength F in stop part 13 earlier, makes this operating portion 131 drive stop part 13 and produces strain and close towards the direction of loading plate 11.
At this moment, by aforesaid positioning unit, with headpin 123 pass the cover hand-hole 151 after, cooperate circuit board 14 and loading plate 11 translation between the two again, then neck post 122 can be snapped in this location hole 152, and make support column 12 and location division 15 finish snap action, and circuit board 14 is positioned on the loading plate 11.
After treating that circuit board 14 is positioned loading plate 11, removal is applied to the strength F on the operating portion 131 again, then stop part 13 will and drive operating portion 131 by reaction force R resilience and return back to original position, and make stop section 132 can be connected to circuit board 14 by stop section 141, and further circuit board 14 is fixed on the loading plate 11.
As mentioned above, prior art with stop part 13 fixing circuit boards 14 on loading plate 11, though can remove the use aid from, yet in the occasion of practical application, no matter dismounting or assembling, all need continue to push down the operating portion 131 of this stop part 13, when treating that the dismounting of circuit board 14 or assembling finish, just can decontrol this operating portion 131.So, then increased and assembled and dismantle required man-hour, moreover, owing to need continue to push down operating portion 131, therefore for also inconvenient in the operation.
Therefore, how to develop a kind of circuit board fixing mechanism, to solve the various shortcomings of above-mentioned prior art, real problem for needing to be resolved hurrily now.
