Abstract
The utility model discloses a printed circuit board device which can be assembled and disassembled reliably, and relates to the technical field of electronic equipment. The structure of the printed circuit board device which can be assembled and disassembled reliably comprises a printed circuit board, and a case or a housing for fixing the printed circuit board. The case or the housing is provided with a fixation column, and the printed circuit board is fixed on the fixation column. According to the utility model, by forming a positioning hole in the printed circuit board and arranging a positioning supporting column corresponding to the positioning hole on the case or the housing, the positioning supporting column passes through the positioning hole and used to support the printed circuit board, and in the printed circuit board assembly and disassembly, fixation elements (eg. blots) for fixing the printed circuit board are all loosened, the printed circuit board is still positioned and supported by the positioning supporting column so as to avoid from being fallen and damaged, so that the assembly and disassembly of the printed circuit board can be facilitated and the assembly and disassembly of the printed circuit board can be safe and realizable.
Description
Technical field
The utility model relates to technical field of electronic equipment, particularly relates to the reliable PCB pcb equipment of a kind of dismounting.
Background technology
Along with the development of miniaturization and portability day by day of various electronic products, it uses the size of circuit board also constantly dwindling, therefore, the PCB wiring board is generally made the PCB wiring board of multilayer, be beneficial to dwindle the volume of electronic product, the PCB wiring board of multilayer generally can not be placed directly in the shell of cabinet or shell or electronic product.
The way of prior art is generally to be provided with fixed leg on cabinet or shell, then the PCB wiring board is arranged on corresponding fixed leg.Yet dismounting and the dismounting of the inconvenient PCB wiring board of this installation method are wasted time and energy, very heavy PCB wiring board particularly, except maintenance or change very inconvenient, may in disassembly process, also can cause the PCB wiring board to fall damage.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art and a kind of easy disassembly and the safe and reliable PCB pcb equipment of dismounting is provided.
The purpose of this utility model is achieved through the following technical solutions:
The reliable PCB pcb equipment of a kind of dismounting, comprise the PCB wiring board and for fixedly cabinet or the shell of PCB wiring board, cabinet or shell are provided with fixed leg, the PCB wiring board is fixed in described fixed leg, the PCB wiring board is provided with location hole, cabinet or shell are provided with the positioning support dagger corresponding with described location hole, and the positioning support dagger is through described location hole and support the PCB wiring board, and the positioning support dagger is higher than fixed leg.
Wherein, the positioning support dagger at least is provided with two.
Wherein, fixed leg is provided with six.
Wherein, described fixed leg is set to hollow and is with externally threaded fixed leg, and the PCB wiring board is secured by bolts in described fixed leg.
Wherein, the positioning support dagger is set to the projection shape.
Beneficial effect:
The reliable PCB pcb equipment of a kind of dismounting of the present utility model, by at the PCB wiring board, being provided with location hole, cabinet or shell are provided with the positioning support dagger corresponding with described location hole, the positioning support dagger is through described location hole and support the PCB wiring board, when dismounting PCB wiring board, will be for after fixedly the fixture of PCB wiring board (as bolt) all unclamps, the PCB wiring board still has the positioning support dagger to position and support, can not fall damage, therefore, facilitate the dismounting of PCB wiring board and make the dismounting of PCB wiring board safe and reliable.
The accompanying drawing explanation
Utilize accompanying drawing to be described further utility model, but the embodiment in accompanying drawing does not form any restriction of the present utility model, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain according to the following drawings other accompanying drawing.
Fig. 1 is that the utility model is unkitted the cabinet of PCB wiring board or the partial structurtes schematic diagram of shell.
Fig. 2 is the structural representation of PCB wiring board.
Fig. 3 is the structural representation of positioning support dagger and PCB wiring board.
In Fig. 1 to Fig. 3, include:
1---fixed leg;
2---the positioning support dagger;
3---location hole;
4---the PCB wiring board.
Embodiment
With the following Examples the utility model is further described.
The reliable PCB pcb equipment of a kind of dismounting of the present embodiment, as depicted in figs. 1 and 2, comprise the PCB wiring board and for fixedly cabinet or the shell of PCB wiring board, cabinet or shell are provided with fixed leg 1, the PCB wiring board is fixed in described fixed leg 1, and the PCB wiring board is provided with location hole 3, and cabinet or shell are provided with the positioning support dagger 2 corresponding with described location hole 3, positioning support dagger 2 is through described location hole 3 and support the PCB wiring board, and positioning support dagger 2 is higher than fixed leg 1.
Wherein, positioning support dagger 2 is higher than fixed leg 1.Positioning support dagger 2 just can be played a supporting role like this.
Wherein, positioning support dagger 2 at least is provided with two.The quantity of positioning support dagger 2 can arrange according to actual needs, and components and parts or the pad on the PCB wiring board need to be avoided in the position that positioning support dagger 2 arranges.
Wherein, fixed leg 1 is provided with six.Can be respectively near the edge on two long limits of corresponding PCB wiring board, arrange three.Certainly, the quantity of fixed leg 1 can arrange according to actual needs.
Wherein, described fixed leg 1 is set to hollow and is with externally threaded fixed leg 1, and the PCB wiring board is secured by bolts in described fixed leg 1.
Perhaps, as shown in Figure 3, positioning support dagger 2 is set to the projection shape.The projection shape refers to that the shape of positioning support dagger 2 is identical with " protruding " word, and the upper end of the positioning support dagger 2 of projection shape, for the location hole 3 through the PCB wiring board, plays the role of positioning, and two shoulders of the positioning support dagger 2 of projection shape are for supporting the PCB wiring board.
The reliable PCB pcb equipment of a kind of dismounting of the present utility model, by at the PCB wiring board, being provided with location hole 3, cabinet or shell are provided with the positioning support dagger 2 corresponding with described location hole 3, positioning support dagger 2 is through described location hole 3 and support the PCB wiring board, when dismounting PCB wiring board, will be for after fixedly the fixture of PCB wiring board (as bolt) all unclamps, the PCB wiring board still has positioning support dagger 2 to support, can not fall damage, therefore, facilitate the dismounting of PCB wiring board and make the dismounting of PCB wiring board safe and reliable.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection range; although with reference to preferred embodiment, the utility model has been done to explain; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not break away from essence and the scope of technical solutions of the utility model.
