Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Shown in referring to Figures 1 and 2, a kind of double-layer PCB board, including the first pcb board 1, assembled with 1 phase of the first pcb board the
Two pcb boards 2, positioning column 3 and positioning seat 4.Positioning column 3 is vertically installed in the side of the first pcb board 1, quantity four, positioning
Seat 4 is installed on the second pcb board 2 and 3 pairs of positioning column setting, quantity four.It is offered on positioning seat 4 and positioning column simultaneously
3 compatible location holes 5, by mutually being assembled between positioning column 3 and location hole 5 so that the first pcb board 1 and the second pcb board 2 it
Between it is in the horizontal direction relative movement limited.It is additionally provided with snap component 6 between positioning column 3 and location hole 5 simultaneously, leads to
The fixing assembling between the realization positioning column 3 of snap component 6 and location hole 5 is crossed, to realize the first pcb board 1 and the second pcb board 2
Between fixing assembling.
Referring to shown in Fig. 2, snap component 6 includes mounting hole 61, limited post 62 and push spring 63.61 edge of mounting hole
The outer wall of positioning column 3 circumferentially opens up, and limited post 62 is mounted in mounting hole 61, and the setting of push spring 63 is in limited post 62 and installation
Between the inner wall in hole 61, while the embedded hole 7 being correspondingly arranged with limited post 62 is offered on the inner wall of location hole 5.It will determine
During position column 3 and location hole 5 are assembled, when positioning column 3 slides to limited post 62 and embedded hole 7 along the inner wall of location hole 5
When the position opened up is corresponding, limited post 62 is against in embedded hole 7 under the elastic force effect of push spring 63, realizes positioning column 3
With the fixing assembling between location hole 5.Enable to limited post 62 towards embedding in running fix column 3 in order to facilitate the operation of person simultaneously
Position that apertured 7 opens up is mobile, offers the guiding being correspondingly arranged with limited post 62 the inner wall of mounting hole 61 is circumferentially spaced
Slot 9, so that limited post 62 can be under the guiding role of guide groove 9 along the position that guide groove 9 is accurately opened up towards embedded hole 7
Set movement.
Referring to shown in Fig. 2, limited post 62 is detached from mounting groove under the thrust of push spring 63 in order to prevent, therefore
The top Screw assembly stop collar 11 of mounting groove, and in limited post 62 close to the bottom end side of mounting groove is fixed and stop collar
11 compatible bulge loops 10, so that bulge loop 10 is pushed against on stop collar 11 and by stop collar in the thrust of push spring 63
11 limit avoids stop collar 11 from being detached from mounting groove.
Referring to shown in Fig. 2 and Fig. 3, embedded hole 7 is the through-hole through 5 inner wall of location hole, and limited post 62 passes through 15 energy of through slot
It is enough to be moved in embedded hole 7, and the one end for limiting the bottom far from mounting hole 61 is equipped with spheric end.When needing to take off limited post 62
Limit from embedded hole 7 when realizing the separation between positioning column 3 and location hole 5, can pass through the past side close to mounting hole 61
To promotion limited post 62, then positioning column 3 is moved up, so that limited post 62 is taken in mounting hole 61 under the action of spheric end,
It continues to move to positioning column 3 and realizes that positioning column 3 is separated with location hole 5.
Referring to shown in Fig. 2, facilitate operator when needing to separate the first pcb board 1 with the second pcb board 2, it is only necessary to successively
The limited post 62 on each positioning column 3 is released, just the first pcb board 1 can be separated with the second pcb board 2, without
Simultaneously the limited post 62 on each positioning column 3 is carried out releasing limit and can complete the first pcb board 1 and the second pcb board 2
Separation.Therefore one baffle 13 is set in 7 inner sliding type of embedded hole, and in the outer wall of baffle 13 close to the side of 5 bottom of location hole
A upper fixed shift plate 14, while positioning seat 4 and embedded hole 7 are offered while be connected on the second pcb board 2, is slided for shift plate 14
Dynamic through slot 15.Iron plate 16, solid magnetic sheet 17 on two opposite inner walls of through slot 15 are installed in 14 two sides of shift plate simultaneously.When needs point
When from the first pcb board 1 and the second pcb board 2, shift plate 14 is pushed toward the direction close to mounting hole 61 and is adsorbed on magnetic sheet 17, from
And the limit for driving baffle 13 that limited post 62 is pushed to be detached from embedded hole 7, the first pcb board 1 and the are moved up so as to realize
Two pcb boards 2 are separated.Simultaneously when needing the first pcb board 1 and the second pcb board 2 assembly is fixed, first toward separate
The direction of mounting hole 61 pushes shift plate 14, so that shift plate 14 is adsorbed on the inner wall of through slot 15, drives baffle 13 by shift plate 14
It moves and is fixed in embedded hole 7, be then able to realize that limited post 62 is embedded in embedded hole 7 and is pushed against on baffle 13, it is real
Fixing assembling between existing positioning column 3 and location hole 5.
The course of work is summarized:
During being assembled the first pcb board 1 and the second pcb board 2, filled using positioning column 3 and location hole 5
Match so that the first pcb board 1 and the second pcb board 2 in the horizontal direction between relative movement be restricted, then in positioning column 3
Interval opens up mounting hole 61 on outer wall, limited post 62 is installed in mounting hole 61, and connect limit simultaneously using push spring 63
The bottom of column 62 and mounting hole 61, so that during positioning column 3 is mobile along the inner wall of location hole 5, when limited post 62
When sliding to corresponding with the position that embedded hole 7 opens up, limited post 62 can be against under the thrust of push spring 63 and be embedded
In hole 7, positioning column 3 is fixedly mounted on the mode for replacing originally needing to install by tool in location hole 5 to realize,
Process is simple and convenient.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
