Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in Fig. 1-6, be the sketch map of the fixed structure embodiment of the many PCB of the utility model.The fixed structure of these many PCB is used for a PCB 20 and the 2nd PCB 30 are installed to housing or installation frame 10.The sidewall of above-mentioned housing or installation frame 10 is provided with first support group and second support group that is positioned at differing heights, and above-mentioned first support group and second support group comprise a plurality of brace rods 11,13 respectively.The brace rod 11 of each support group in first support group and second support group or 13 end face are positioned at same plane.The lower surface of the one PCB 20 and the 2nd PCB 30 (being the edge of PCB lower surface in the present embodiment) is erected at respectively on first support group and second support group.
Individual in the present embodiment, first support group is positioned at second support group below, and first support group is positioned at the inboard of second support group.Correspondingly, a PCB 20 in the size of fixed-direction (the for example Width of Fig. 1 middle shell or installation frame 10) less than the 2nd PCB 30.Like this, a PCB 20 who is positioned at lower floor can be attached on first support group easily, and the 2nd PCB 30 that is installed in second support group also is not easy to be slipped to first support group of lower floor.Particularly, a PCB 20 is relevant with concrete equipment in the difference of the size of fixed-direction with the 2nd PCB 30, and for example both differences can be 2 millimeters.
First above-mentioned support group and the brace rod of second support group 11,13 lay respectively at the relative sidewall of housing or installation frame 10, and a PCB 20 or the 2nd PCB 30 that can guarantee like this to set up above that keep stable.In addition, the brace rod 11,13 of first support group and second support group also can lay respectively at three or four sidewalls of housing or installation frame 10.
And; In above-mentioned first support group and second support group at least part brace rod 11,13 be positioned at housing or installation frame 10 sidewall same position and for step, promptly the end face of support the one PCB 20 and support the 2nd PCB30 is positioned on the same fin and individual end face and fin composition step.Certainly, in concrete the application, the shape of brace rod 11,13 and structure can adopt arbitrarily existing mode, as long as can carry out layering support PCB.
Certainly, in practical application, also can increase support column etc., it carried out support with middle part at PCB in the bottom of housing.
In order to realize that a PCB 20 and the 2nd PCB's 30 is fixing; First corresponding with first support group and the second support group respectively buckle group and the second buckle group can be set on the sidewall of housing or installation frame 10, and this first buckle group and the second buckle group comprise a plurality of buckles 12,14 respectively. Buckle 12,14 is positioned at the relative sidewall of housing or installation frame 10, and hook portion is downward.At a PCB 20 or the 2nd PCB 30 fixedly the time, buckle 12 or 14 hook portion are resisted against the upper surface of a PCB 20 or the 2nd PCB 30, thereby clamp PCB with brace rod 11 or 13, thereby realize fixing.
The sidewall of above-mentioned brace rod 11,13 and buckle 12,14 and housing or installation frame 10 is one-body molded.In concrete the application, the wallboard of above-mentioned brace rod 11,13 and buckle 12,14 also can be positioned on the wallboard of independent processing, then this wallboard is fixed to the housing with smooth surface.
In the fixed structure of above-mentioned many PCB, can comprise that also the 3rd PCB 40, the three PCB 40 are erected on the brace rod 13 of second support group, and fixing through the buckle 14 of the second buckle group.In the present embodiment, the 2nd PCB 30 and the 3rd PCB 40 equal the size of back less than this direction the one PCB 20 after the size of on-fixed direction.Like this, just formed the double-deck mounting structure of three PCB.
In the said fixing structure, be respectively equipped with corresponding spininess socket 22 and plug 42 on a PCB 20 and the 3rd PCB 40 facing surfaces, through cooperating of plug 42 and socket 22, realize being electrically connected of a PCB 20 and the 3rd PCB 40.Correspondingly, be respectively equipped with corresponding spininess plug 21 and socket 31 on a PCB 20 and the 2nd PCB 30 facing surfaces, thereby realize being electrically connected of a PCB 20 and the 2nd PCB 30.
