Abstract
The utility model discloses a fixing structure of a circuit board in a sheet metal box, in particular to bend angle supports which are formed integrally with a bottom board of the sheet metal box and are used to support and fix the circuit board. The bend angle supports are formed through blanking elongated sheet metals whose side edges are integrally connected on the bottom board of the sheet metal box and then bending the sheet metals upwards for 90 degrees along the connecting portion between the sheet metals and the bottom board of the sheet metal box, the elongated sheet metals can form vertical shapes with the bottom board of the sheet metal box, then, the elongated sheet metals are bended for 90 degrees, the bended parts form parallel shapes with the bottom board of the sheet metal box, and thereby forming the bend angle supports. A screw hole is opened on a part of the bend angle support, which is in parallel with the bottom board of the sheet metal box. Bend angle supports are evenly distributed on the bottom board of the sheet metal box, the number is same with positioning through holes of the circuit board. The fixing structure has convenient technique, high positioning precision and artistic outer shape, the fixing structure is suitable for being produced in large scale, and the through hole on the bottom is beneficial for the box to dissipate heat. The sheet metal box does not need using an interval column and also prevents screw bolts from exceeding the bottom of the box.
Description
Technical field
The utility model relates to a kind of circuit board fixing in Sheet-metal machine box, and it is easy particularly to relate to a kind of technology, firmly is suitable for circuit board aesthetic in appearance fixed structure in Sheet-metal machine box.
Background technology
The electrotechnical, electronic kind equipment generally adopts Sheet-metal machine box, plays the protective effect to the circuit board electronic device.Circuit board is at Sheet-metal machine box, and particularly the fixed form at the Sheet-metal machine box base plate has following two kinds usually:
1, shown in Fig. 1-1,1-2, directly tapping on base plate 1, spacer 7 is fixed on the base plate 1 by screw thread, circuit board 3 is fixed on the spacer 7 again.The advantage of this kind structure is that processing is simple.Shortcoming is that the panel beating wall is thin, and the male end 8 of spacer can exceed the cabinet bottom surface, causes cabinet bottom surface injustice.
2, as shown in Figure 2, welding bent angle metallic plate 6 is fixed to circuit board 3 on the bent angle metallic plate 6 again on chassis backplane 1.This mode advantage is to have avoided bolt to penetrate the wallboard bottom surface to cause the bottom surface injustice.Shortcoming is that technology is loaded down with trivial details: if tapping on the bent angle metallic plate earlier, after it is welded on the base plate, then its positioning accuracy is difficult to guarantee; If earlier the bent angle metallic plate is welded on the base plate, back tapping, because face closure under the bent angle metallic plate, frock clamp is difficult to make, processing inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of technology easy, firmly is suitable for circuit board aesthetic in appearance fixed structure in Sheet-metal machine box.
The technical scheme that the utility model adopted is: the fixed structure of a kind of circuit board in Sheet-metal machine box, include the Sheet-metal machine box base plate, and on the Sheet-metal machine box base plate, have to support with the bent angle of fixing circuit board and support with integrally formed being used to of Sheet-metal machine box base plate.
It is after Sheet-metal machine box base plate upper punch is determined a side one and is connected in strip sheet metal on the Sheet-metal machine box base plate that described bent angle supports, 90 ° of bendings make progress along itself and Sheet-metal machine box base plate connection, make the strip sheet metal become vertical shape with the Sheet-metal machine box base plate, then, again with 90 ° of strip sheet metal bendings, make by the folding part branch to become parallel in shape, support thereby form bent angle with the Sheet-metal machine box base plate.On the part parallel that bent angle supports, have screw with the Sheet-metal machine box base plate.
Described bent angle supports 2 and evenly distributes on Sheet-metal machine box base plate 1, and number is identical with the positioning through hole of circuit board 3.
The fixed structure of circuit board of the present utility model in Sheet-metal machine box, technology is easy, and the positioning accuracy height is aesthetic in appearance, be fit to produce in enormous quantities, and the perforate of bottom surface is beneficial to case radiation.The utility model need not use spacer, has avoided screw to exceed the cabinet bottom surface yet.

Embodiment
Provide specific embodiment below in conjunction with accompanying drawing, further specify the fixed structure of circuit board of the present utility model in Sheet-metal machine box and how to realize.
Shown in Fig. 3-1, Fig. 3-2, the fixed structure of circuit board of the present utility model in Sheet-metal machine box includes Sheet-metal machine box base plate 1, has to support with the bent angle of fixing circuit board 3 with 1 integrally formed being used to of Sheet-metal machine box base plate on Sheet-metal machine box base plate 1 to support 2.
It is to determine a side one in Sheet-metal machine box base plate 1 upper punch to be connected in strip sheet metal on the Sheet-metal machine box base plate 1 that described bent angle supports 2, and 90 ° of the bendings that make progress along itself and Sheet-metal machine box base plate 1 connection, make 1 one-tenth vertical shape of strip sheet metal and Sheet-metal machine box base plate, then, again with 90 ° of strip sheet metal middle part bendings, make by the folding part and divide and 1 one-tenth parallel in shape of Sheet-metal machine box base plate, support 2 thereby form bent angle.Support at bent angle on 2 the part parallel and have screw 4 with Sheet-metal machine box base plate 1.
Described bent angle supports 2 and evenly distributes on Sheet-metal machine box base plate 1, and number is identical with the positioning through hole of circuit board 3.
Shown in Fig. 3-3, when fixing circuit board 3, circuit board 3 is placed on by on a plurality of bent angles support 2 supporting surfaces that constitute, and with the screw 4 corresponding placements of the location hole on the circuit board with bent angle support 2, with screw 5 circuit board 3 being fixed on bent angle supports on 2, avoid using spacer, also avoided screw to exceed the cabinet bottom surface.
