Specific embodiment
To facilitate the understanding of the present invention, the present invention is further detailed with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of circuit board fixation structure of the present invention, including fixed bin 2 and at least one clamp 1, institute
Clamp 1 is stated to be made of chassis 11, cantilever 12 and guide post 13；13 chassis 11 of guide post is coaxially connected, and guide post 13 is central axial to be set
There is screw hole, screw hole is matched with the screw for fastening；Cantilever 12 is by bending part 121 and is arranged in 121 bent end of bending part
Barb 122 form, the upward bending of bending part 121, barb 122 flexes outward；At least two cantilevers 12 are centered on guide post 13
Circumferentially uniformly it is connected to 11 periphery of chassis；The fixed bin 2 is equipped with multiple card slots 21 matched with clamp 1, the card
Slot 21 includes boss 212, the circular hole 211 passed through for guide post 13 and the square groove 213 passed through for cantilever 12, after cantilever 12 passes through square groove
Barb 122 is stuck on boss 212.When being installed to various sizes of circuit board, as shown in figure 3, only need to first select properly
Card slot 21 and appropriate number of clamp, clamp 1 is inserted into card slot 21, guide post 13 is inserted into from circular hole 211, and cantilever 12 is from correspondence
Square groove 213 in be inserted into and cantilever 12 bending part 121 pressed to intermediate deformation contraction, when clamp 1 is fully inserted into card slot 21
In after, the bending part 121 of cantilever 12, which flexes outward, is stuck in barb 122 on corresponding boss 212, as shown in figure 4, using screw again
It is fastened, it is easy to assembly, versatile.
When clamp 1 is fastened in card slot 21, cantilever 12 is rolled on cantilever 12 known to force analysis by inward pressure
The length dimension a of turn of bilge 121 should be greater than height dimension b, and 12 stress balance of cantilever can will not just be broken；Further
, the length dimension of bending part 121 and the height dimension of bending part 121 should meet relationship a > 2b.
As shown in Fig. 2, barb 122 is up-small and down-big slope structure or similar bevel structure, then clamp 1 is being inserted into
The deformation quantity of cantilever 12 is not too big during card slot 21, while clamp 1 can also be made to be easier to be inserted into card slot 21.
As shown in Fig. 2, it is more convenient in order to make to dismantle clamp 1, fillet is set by the bill part of barb 122, is being torn open
When inwardly squeezing barb 122 when unloading clamp 1, barb 122 is easier to fall off from boss 212.
Setting may be selected in the quantity of cantilever 12, under the premise of guaranteeing that clamp 1 engages firm with card slot 21, reduces to the greatest extent outstanding
12 quantity of arm, although because 12 quantity of cantilever can excessively make clamp 1 more firm with the engaging of card slot 21, when loading and unloading clamp 1
Difficulty also increase much, while be also required to increase card slot 21 on square groove 213 and boss 212 quantity, increase mold opening cost, because
This it is preferred that, it is three cantilevers 12 that quantity is selected in the present embodiment.
Clamp 1, which should be selected, to be had certain elasticity, can bear the hard material of deformation quantity to a certain degree to prepare, and just can guarantee
The cantilever 12 in assembling and dissembling process of clamp 1 will not be broken because deformation occurs, select ABS plastic as clamp 1 in the present embodiment
Material, elasticity, the intensity of ABS plastic are suitable for clamp 1, and wearability is strong, in Reusability clamp 1, clamp 1 and card slot
Amount of friction is larger between 21, selects ABS plastic that can reduce the abrasion of clamp 1；In order to guarantee the integrally-built intensity of clamp 1, block
Cantilever 12, chassis 11 and guide post 13 on son 1 are integrally formed by plastic compression.
