Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The utility model embodiment provides a kind of backboard, as shown in Figure 2 a and 2 b, comprises elastic bending part 21, and an end 211 of elastic bending part 21 is fixedly connected with backboard 22, and elastic bending part 21 is as a whole with 22 one-tenth of backboards like this.The other end 212 toward back plate 22 direction bendings of elastic bending part 21, and be connected with convex closure 23, convex closure 23 can weld or be bonded on elastic bending part 21, convex closure 23 can be connected with the hole 241 on printed circuit board (PCB) 24, convex closure 23 matches with the hole 241 on printed circuit board (PCB) 24, makes convex closure 23 just be contained in hole 241.
When being assembled into printed circuit board (PCB) 24 on backboard 22, printed circuit board (PCB) 24 is placed on the top of backboard 22.Have hole 241 on printed circuit board (PCB) 24, this hole 241 can be that through hole can not be also through hole.If the hole on printed circuit board (PCB) 24 241 is through hole, the one side of printed circuit board (PCB) 24 contacts with backboard 22 so, another side and backboard 22 deviate from; If the hole 241 on printed circuit board (PCB) 24 is not through hole, the one side of printed circuit board (PCB) 24 porose 241 deviates from backboard 22 placements so, because elastic bending part 21 has elasticity, therefore convex closure 23 upwards can be lifted, make the original position while not producing deformation (be elastic bending part 21 the corresponding position of convex closure 23) of hole 241 and convex closure 23 on printed circuit board (PCB) 24 corresponding, again convex closure 23 is put back to and made it return to original position, this moment, convex closure 23 was placed in the hole 241 of printed circuit board (PCB) 24.When printed circuit board (PCB) 24 is dismantled from backboard 22,, because elastic bending part 21 has elasticity, convex closure 23 can be lifted from hole 241, then printed circuit board (PCB) 24 is moved to not the position that clashes with convex closure 23, namely complete dismounting.Convex closure 23 is discharged,, because elastic bending part 21 has elasticity, make convex closure 23 can return to original position.
The backboard that the utility model embodiment provides, owing to printed circuit board (PCB) 24 being assembled into backboard 22 or while from backboard 22, dismantling, only need will with elastic bending part 21 on the hole 241 of convex closure 23 from printed circuit board (PCB) 24 just put into or take out and can complete, so step is simple, easily operates.
in the backboard that above-described embodiment provides, convex closure 23 can be apart from certain altitude h with backboard 22, this height h can be less than or equal to the thickness m of printed circuit board (PCB) 24, due to the one side 243 of printed circuit board (PCB) 24 and one side 221 laminatings of backboard 22, be printed circuit board (PCB) 24 with the another side 242 of backboard 22 laminating, do not equal the thickness m of printed circuit board (PCB) apart from the distance of backboard 22, and convex closure 23 is less than or equal to the thickness m of printed circuit board (PCB) 24 apart from the height h of backboard 22, can guarantee that like this convex closure 23 is contained in hole 241 whole or in part, thereby reach the purpose that printed circuit board (PCB) 24 and backboard 22 more firmly are fixedly connected with.
Usually, the hole on printed circuit board (PCB) 24 is circular hole, the xsect of convex closure 23 can be designed to circle so, and convex closure 23 center lines can be perpendicular to backboard 22.The profile of convex closure 23 and the circular hole on printed circuit board (PCB) 24 are more mated.While making printed circuit board (PCB) 24 and backboard 22 assembling, convex closure 23 increases with the surface area that circular hole contacts with each other.Further, if the center line of convex closure 23 is perpendicular to backboard 22, in the time of can making convex closure 23 put into circular hole on printed circuit board (PCB) 24, perpendicular to the surface of contact of printed circuit board (PCB) 24 with backboard 22, the center line of convex closure 23 overlaps with the center line of circular hole or is parallel so, can realize convex closure 23 and circular hole interference fit.Thereby make backboard 22 be connected more firm effect with printed circuit board (PCB) 24.
In the backboard that above-described embodiment provides, as shown in Fig. 3 a, elastic bending part 21 can be connected in turn by first side 31, Second Edge 32, the 3rd limit 33, for example can form one inverted U-shaped; First side 31 is fixedly connected with backboard 22, and an end on the 3rd limit 33 is connected with convex closure 23.
Because the end on the 3rd limit 33 is connected with convex closure 23, when convex closure 23 being lifted or discharges, can be that only elastic deformation occurs on the 3rd limit 33, elastic deformation occur or elastically-deformable degree occurs less in first side 31 and Second Edge 32, makes the one-piece construction of elastic bending part 21 more stable.When elastic deformation occurs in the 3rd limit 33, owing to being provided with Second Edge 32 between first side 31 and the 3rd limit 33, therefore power need to could arrive first side 31 via the transmission of Second Edge 32, thereby reduce first side 31, elastically-deformable probability occurs, so that first side 31 is more firm with being connected of backboard 22.
In the backboard that above-described embodiment provides, as Fig. 3 b first side 31 perpendicular to backboard 22, Second Edge 32 is parallel to backboard 22, the 3rd limit 33 is obtuse angle with Second Edge 32 angles, thereby the elastic bending part 21 that first side 31, Second Edge 32, the 3rd limit 33 form can be one-body molded by punching press, and while making like this, mould is easily made., if the angle of the 3rd limit 33 and Second Edge 32 is acute angle or right angle, make the 3rd limit 33 that elastic deformations occur, so that convex closure 23 while lifting smoothly, is not easy to operation.The 3rd limit 33 is obtuse angle with Second Edge 32 angles, makes the operator lift or while discharging convex closure 23, elastic deformation, convenient operation more easily occur on the 3rd limit 33.
In the backboard that above-described embodiment provides, elastic bending part can only have first side 31, and namely first side 31 1 ends are fixedly connected with backboard 22, and the other end connects convex closure 23.First side 31 shapes can be arch.Can achieve the goal equally.But when elastic deformation occurred first side 31, its end that is connected with backboard 22 was easy to stressed generation deformation, causes the structural change of backboard 22, and therefore, practicality is poor.
Further, elastic bending part 21 can be connected to form an inverted V-shaped in turn by first side 31, Second Edge 32, and first side 31 1 ends are fixedly connected with backboard 22, and an end of Second Edge 32 is connected with convex closure 23.The elastic bending part 21 of this form is slightly better than the situation that first side 31 is only arranged, and still, practicality is still than the poor practicability of the elastic bending part 21 that is comprised of first side 31, Second Edge 32, the 3rd limit 33.
In the backboard that above-described embodiment provides, as shown in Figure 4, convex closure 23 can comprise flank 41, and convex closure 23 is connected with the 3rd limit 33 by flank 41, and the connected mode on flank 41 and the 3rd limit 33 can be welding or bonding.When hole 241 on printed circuit board (PCB) 24 was connected, flank 41 and printed circuit board (PCB) 24 laminatings, made the position in the hole 241 of convex closure 23 in printed circuit board (PCB) 24 more stable, is not easy to produce and rocks when convex closure 23.Simultaneously, also increase the contact area of convex closure 23 with printed circuit board (PCB) 24, made the stable connection of backboard 22 and printed circuit board (PCB) 24.
In the backboard that above-described embodiment provides,, referring to Fig. 4, can be provided with 42, the four limits 42, the 4th limit on flank 41 and can be welded on flank 41, perhaps one-body molded with flank 41.When convex closure 23 coordinates with printed circuit board (PCB) 24, do not fit with printed circuit board (PCB) 24 in the 4th limit 42.Like this, when needs lifted convex closure 23, the 4th limit 42 can be used as handle and uses, and the operator is easy to the 4th limit 42 of perk is lifted, and to reach the purpose that convex closure 23 is lifted, so the convenient operation person successfully mentions convex closure 23.
In the backboard that above-described embodiment provides, as shown in Figure 5, elastic bending part 21 can be structure as a whole with backboard 22 and by backboard 22 impact briquettings.Like this, do not need elastic bending part 21 and backboard 22 are made separately, then, with the step that they connect, simplified processing step; Convex closure 23 on elastic bending part 21 and the flank 41 on convex closure 23, all, with backboard 22 integrated punching moulding, make between each parts and do not have junction, therefore do not have the junction factors of instability, makes the structure of backboard 22 more stable; And punch forming process is simple, cost is lower, is easy to realize.
In the backboard that above-described embodiment provides, elastic bending part 21 also can be welded to connect with backboard 22.Be welded to connect firmly, firm, technical maturity, be easy to realize, makes elastic bending part 21 firmly with backboard 22, be connected.
