Abstract
The utility model discloses a kind of pcb board fixed structure, comprise metal shell and pcb board, inside metal shell, be provided with elastic pressuring plate; Backstop is provided with elastic pressuring plate adjacent in metal shell; In metal shell, the both sides of elastic pressuring plate are symmetrically arranged with bracing frame; Bottom metal shell, rear end is provided with the convex closure of tapping, and pcb board is fixed in metal shell by bracing frame, convex closure and elastic pressuring plate.Pcb board is fixed in metal shell by the bracing frame in metal shell, convex closure and elastic pressuring plate by the utility model, the lower surface of pcb board is supported by bracing frame and convex closure, pcb board upper surface is fixed by elastic pressuring plate and is being done paving Copper treatment with elastic pressuring plate contact position, under the prerequisite that pcb board tightens up by elastic pressuring plate, realize the electrostatic conducting between pcb board and elastic pressuring plate.The utility model structure is simple, easy for installation, does not use nut, pcb board can operations area large, improve the efficiency of pcb board welding, and then reduce production cost, alleviate the pollution level to environment, to operator's health without harm.
Description
Technical field
The utility model belongs to pcb board mounting technique field, particularly a kind of pcb board fixed structure.
Background technology
It is fastening that the support column of pcb board employing in the past adds screw and nut, should not carry out wrench operated at small space; Even welded nut, under not using spanner situation, welding is also to spend a large amount of electric power, affects environment, has certain injury to operator's health.In addition, general pcb board will do grounding, prevents components and parts electrostatic breakdown, structurally will do electrostatic conducting structure.
Utility model content
To be solved in the utility model to be that existing pcb board is fixing adopt support column to add screw-nut to tighten up, inconvenient operation, a large amount of electric power of welding cost, and contaminated environment produces injury to operator, and cost is high and the PCB electrostatic conducting technical problem such as not easily.Thus provide a kind of easy to operate, the pcb board fixed structure that cost is low.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows:
A kind of pcb board fixed structure, comprises metal shell and pcb board, is provided with elastic pressuring plate inside metal shell; Backstop is provided with elastic pressuring plate adjacent in metal shell; In metal shell, the both sides of elastic pressuring plate are symmetrically arranged with bracing frame; Bottom metal shell, rear end is provided with the convex closure of tapping, and pcb board is fixed in metal shell by bracing frame, convex closure and elastic pressuring plate.
The height of support frame as described above is less than the height of elastic pressuring plate, allows and is placed between the two by pcb board.
Difference in height between described elastic pressuring plate and bracing frame is not more than the thickness of pcb board, and this structure ensures that pcb board compresses by elastic pressuring plate.
The height of described convex closure equals the height of bracing frame, keeps pcb board to be horizontal.
Difference in height between described backstop and bracing frame is less than the thickness of pcb board, limits the position of pcb board.
Described pcb board is being equipped with copper with elastic pressuring plate contact position, makes realize electrostatic conducting between elastic pressuring plate and pcb board.
The utility model is by being fixed in metal shell by the bracing frame in metal shell, convex closure and elastic pressuring plate by pcb board, the lower surface of pcb board is supported by bracing frame and convex closure, pcb board upper surface is fixed by elastic pressuring plate and is being done paving Copper treatment with elastic pressuring plate contact position, under the prerequisite that pcb board tightens up by elastic pressuring plate, realize the electrostatic conducting between pcb board and elastic pressuring plate.In convex closure position, pcb board is fixed by screws on convex closure.The utility model structure is simple, easy for installation, does not use nut, pcb board can operations area large, easy to operate, thus improve the efficiency of pcb board welding, and then reduce production cost, alleviate the pollution level to environment, to operator's health without harm.

Embodiment
Embodiment: as Figure 1-5, a kind of pcb board fixed structure, comprises metal shell 1 and pcb board 2, is provided with elastic pressuring plate 3 inside metal shell 1.Backstop 4 is provided with elastic pressuring plate 3 adjacent in metal shell 1.In metal shell 1, the both sides of elastic pressuring plate 3 are symmetrically arranged with bracing frame 5.The height of bracing frame 5 is slightly smaller than the height of elastic pressuring plate 3, and bracing frame 5 and elastic pressuring plate 3 difference in height are between the two slightly smaller than the thickness of pcb board 2.Difference in height between bracing frame 5 and backstop 4 is less than the thickness of pcb board.Bottom metal shell 1, rear end is provided with the convex closure 6 of tapping.The height of convex closure 6 equals the height of bracing frame 5.
Pcb board 2 lower surface is supported by bracing frame 5 and convex closure 6, and pcb board 2 upper surface is fixed by elastic pressuring plate 3, and is being equipped with copper with elastic pressuring plate 3 touching position, realizes the electrostatic conducting of elastic pressuring plate 3 and pcb board 2.Be fixed by screws on convex closure 6 at convex closure 6 position pcb board 2.
The upper surface of bracing frame 5 is aimed in pcb board lower surface, and stretch out direction along elastic pressuring plate 3 and advance, top, pcb board edge is to backstop 4.Now pcb board is fixed by convex closure with screw.
