Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Orientation hereinafter described determines according to the locations of structures relation shown in Fig. 1, Fig. 2.
As depicted in figs. 1 and 2, for printed circuit board, stationary device is installed, comprise fixed bin 1, cover plate 2, bulge-structure 3, bulge-structure 3 quantity is two, cover plate 2 can cover on fixed bin 1, as shown in Figure 1, looks over from front, be fixedly installed on the inner surface in arranged on left and right sides face of fixed bin 1 respectively, bulge-structure 3 forms draw-in groove 4 with the inner surface of the downside of fixed bin 1; The inner surface of fixed bin 1 leading flank is provided with to recline and blocks printed circuit board side first positive stop lug boss 11; The inner surface of cover plate 2 downside is provided with to recline and blocks the second positive stop lug boss 23 of printed circuit board top margin.
Particularly, cover plate 2 can cover tightly on fixed bin, the concrete measure adopted is: the upper end of fixed bin 1 left surface is provided with left fixing buckle boss 12, the upper end of fixed bin 1 right flank is provided with right fixing buckle boss 13, cover plate 2 left surface is provided with can be fixed with a left side left side that buckle boss 12 is connected and fix buckle 21, is provided with to fix with the right side right side that buckle boss 13 is connected and fix buckle 22 on the right side of cover plate 2.So buckle boss 12 is fixed on the left side on fixed bin 1 and buckle boss 13 is fixed on the right side, buckle 21 is fixed on the left side on cover plate 2 and buckle 22 is fixed on the right side, is connected between them, and cover plate 2 can be made to cover tightly on fixed bin 1.
Concrete, the effect of bulge-structure 3 forms draw-in groove 4 with the inner surface of the downside of fixed bin 1, two bulge-structures 3 form two draw-in grooves 4, lay respectively on the inner surface in arranged on left and right sides face of fixed bin 1, the effect of draw-in groove 4 allows printed circuit board be arranged on fixed bin 1 li along draw-in groove 4, so the width of draw-in groove 4 should be equal with the thickness of printed circuit board.Bulge-structure 3 front becomes " convex " word shape, has the place of bending to be provided with arc transition.Bulge-structure 3 is arranged to upper part and is less than lower part, is conducive to printed circuit board and inserts draw-in groove 4 li.
Particularly, the effect of the first positive stop lug boss 11 is formed to block with the inner surface of the downside of fixed bin 1 to stitch, and the width of card seam arranges equal with the thickness of printed circuit board.When printed circuit board inserts in card seam, the first positive stop lug boss 11 can recline and block the side of printed circuit board, plays fixing printed circuit board side.First positive stop lug boss 11 quantity is at least 1, and quantity is more, and fixed effect is better, and corresponding cost is corresponding increase also, preferably selects two to three.
Particularly, the effect of the second positive stop lug boss 23 is when cover plate 2 covers at fixed bin 1, and the second positive stop lug boss 23 can recline and block the top margin of printed circuit board, plays fixing printed circuit board equally.Second positive stop lug boss 23 quantity is at least 1, and quantity is more, and fixed effect is better, and corresponding cost is corresponding increase also, preferably selects two to three.
Some printed circuit board positive and negative is provided with particular/special requirement, positive and negative can not setup error, the utility model is also provided with the first inverse plugging boss 14, first inverse plugging boss 14 is arranged on the inner surface of fixed bin 1 leading flank, abut in the inner surface of fixed bin 1 upper side, quantity at least 1, can prevent the insertion of printed circuit board effectively.
Covering instead to prevent cover plate 2 and to cause damage to printed circuit board, also can arrange the second inverse plugging boss 25, the second inverse plugging boss 25 on cover plate 2 is arranged on the inner surface of described cover plate 2 downside, and the second inverse plugging boss 25 quantity is at least 1.When cover plate 2 has covered instead, due to the existence of the second inverse plugging boss 25, cover plate 2 will not cover, and avoids the damage because having covered anti-the printed circuit board caused.
Can more fixedly secure in fixed bin 1 to further make printed circuit board, also the 3rd positive stop lug boss 24 can be set at cover plate 2,3rd positive stop lug boss 24 quantity is 2, be separately positioned on the inner surface in cover plate 2 arranged on left and right sides face, 3rd positive stop lug boss 24 can recline and block printed circuit board arranged on left and right sides limit, strengthens fixing printed circuit board.
First positive stop lug boss 11, first inverse plugging boss 14, second positive stop lug boss 23 mentioned above, the shape of the 3rd positive stop lug boss 24, second inverse plugging boss 25 can be cuboid, square or cylinder, and result of use is all fine.
In sum, fixing by fixed bin 1, cover plate 2, bulge-structure 3, draw-in groove 4, first positive stop lug boss 11, second positive stop lug boss 23 and the 3rd positive stop lug boss 24 pairs of printed circuit boards, makes each direction fix, and installs good fixing effect.
Cover plate 2 is provided with data-interface 26, connects printed circuit board and external devices.
