Abstract
The utility model relates to a fixed supporting frame for a circuit board. The fixed supporting frame for a circuit board is composed of an upper layer and a lower layer which are integrated into integration. The upper layer is a stud, and the center of the stud has a circular through hole. The lower layer is fixed feet which are distributed uniformly at the circumference of the stud. The lower part of each fixed foot is provided with a barb. A positioning slot is arranged on the bottom plate, and matches with the fixed feet. Consequently, when a circuit board is arranged on the supporting frame, only tapping screws are needed to screw the circuit board and the fixed supporting frame tightly. When used, the utility model needs not tooling. The utility model has the advantage of good processing property.
Description
The utility model belongs to fixed support, is specifically related to the member of fixing circuit board on the inner metal sheet of electric equipment.
Before the utility model is made, be sheet metal component, run into the support problem of fixing circuit board in the above of utilizing in the production usually at many members of electrical equipment such as VCD, DVD, power amplifier.The support of being used always in producing at present has multiple version, but all has some problems.Support as shown in Figure 1 is the metal column of a center tapping, and production is to utilize tool locating, and will go up screw twice, and manufacturability is relatively poor.Support as shown in Figure 2 is the plastic column of a hollow, and the base plate flange is handled, and is used for screwing, does not have the location when its is produced, and also need utilize frock.If on its structure, increase by two reference columns it is located on base plate, also will increase by two location holes more simultaneously on the base plate, in very short distance, dash three holes, and a middle hole needs flange to handle, bring very big difficulty for the Mould Machining of base plate.Support as shown in Figure 3, advantage are to use conveniently, and manufacturability is better, but can not realize rigidly fixing of circuit board, and stressedly come off easily.
For addressing the above problem, goal of the invention of the present utility model provides a kind of automatic location, and only needs last screw to get final product the circuit board fixed support of good manufacturability.
For addressing the above problem, the utility model is to realize like this, a kind of circuit board fixed support, this circuit board constitutes by making the two-layer up and down of one with fixed support, top is the double-screw bolt that the center is equipped with manhole, the bottom is a fixing feet, and the fixing feet circumference uniform distribution is in double-screw bolt, and the fixing feet bottom is provided with barb.
Described circuit board is that this circuit board is arranged to 2-3 with support bracket fastened fixing feet with support bracket fastened a kind of improvement.
Advantage of the present utility model and good effect are, the location notch that matches with fixing feet is set on base plate, mounting circuit boards just only needs with tapping screw circuit board and this fixed support are screwed tight and get final product on support like this, and the location between this fixed support and the sheet metal component and fix and realize by the barb of this fixed support fixing feet.So this circuit board is simple with fixing rack structure, the fit structure of base plate and support is also simple during use, need not frock during production, and good assembling process.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is that a kind of circuit board before the utility model is made uses structural representation with fixed support;
Fig. 2 is that the utility model is made former another kind of circuit board and used structural representation with fixed support;
Fig. 3 is that the utility model is made former another kind of fixed support use structural representation;
Fig. 4 is the front view of an embodiment of the utility model;
Fig. 5 is the use structure chart of an embodiment of the utility model.
As shown in Figure 4, a kind of circuit board fixed support, this circuit board constitutes by making the two-layer up and down of one with fixed support, top is the double-screw bolt 1 that the center is equipped with manhole 3, the bottom is a fixing feet 2, and fixing feet is arranged to 2-3, and makes cylindrical, and circumference uniform distribution is in double-screw bolt, and the fixing feet bottom is provided with barb 4.
As shown in Figure 6, at two positioning round orifice 6 that match with fixing feet 2 of sheet metal base plate 5 upper punches; This circuit board matches with the screw that will use with the diameter of support bracket fastened central circular through hole 3 simultaneously, and as being the tapping screw of 3mm with nominal diameter, the diameter in hole can be made 2.5mm.When using this fixed support, utilize this circuit board fixing feet to be inserted base plate, with tapping screw circuit board 7 is fixed on the fixed support then with the strain of fixed support fixing feet 2.This fixed support is moved upward by the effect of tapping screw, makes the outside of fixing feet 2 be close to the positioning round orifice 6 that matches with it and since the barb of fixing feet with circuit board with firm being fixed on the sheet metal base plate of fixed support.Under the situation that does not unload screw, even two posts are subjected to the external force effect, circuit board can not come off with fixed support yet.By fixed support, circuit board can be fixed on base plate or other metal sheet like this.
