Just, and it is unfavorable for automated production.Therefore, it is necessary to design a kind of switching power supply structure, it is able to achieve quick group of Switching Power Supply
It fills and is conducive to automated production.
Utility model content
More than solving the problems, such as, the utility model proposes one kind to be able to achieve the installation of circuit board screwless and quick group
A kind of Switching Power Supply of dress.
The technical solution of the utility model is achieved in that
The utility model discloses a kind of Switching Power Supply, including metal bottom shell, metal top cover, circuit board and plastic frame, institutes
It states metal top cover and the metal bottom shell snaps connection to form cavity, the plastic frame is fixed on the cavity bottom, the electricity
Road plate is fixed in the plastic frame, and the plastic frame two sides are provided with fixing buckle, when being packed into circuit board, the fixing buckle
The fixation hole that the circuit board two sides can be buckled into automatically, plays the role of fixing circuit board, when removing circuit board, pulls described
Fixing buckle, the fixing buckle leave the fixation hole of the circuit board two sides, it can take out circuit board.
Further, the metal top cover two sides are equipped with bending part, and the bending part is integrally torn open curved with the metal top cover
Molding.
Further, a cooling fin is fixed on the inside of the metal top cover, the cooling fin is used for the circuit board
It is connect with metal top cover and passes through the metal top cover and radiated.
Further, the metal top cover is equipped with the venetian blind type radiator window for ventilation and heat.
Implement a kind of Switching Power Supply of the utility model, there is technical effect beneficial below:
It is different from circuit board in Switching Power Supply currently on the market to be fixed by screws in Switching Power Supply shell, this technology side
Case is buckled by fixing buckle in the fixation hole of circuit board two sides, thus fixing circuit board, installation and convenient disassembly.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the schematic diagram of internal structure of the Switching Power Supply of the utility model；

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1, Fig. 2 and Fig. 3, a kind of Switching Power Supply 100 of the embodiments of the present invention, 1 He of metal bottom shell
Metal top cover 2 is all made of aluminium sheet bending and molding, and passes through oxidation processes, not only enhances aesthetics, but also have anti-corrosion function.This is opened
Powered-down source 100 includes metal bottom shell 1, metal top cover 2, circuit board 3 and plastic frame 4, and metal top cover 2 and the buckle of metal bottom shell 1 connect
It connects to form cavity 5, plastic frame 4 is fixed on 5 bottom of cavity, and circuit board 3 is fixed in plastic frame 4, is provided in 4 two sides of plastic frame
Fixing buckle 6, when being packed into circuit board 3, fixing buckle 6 can buckle into the fixation hole (not shown) of 3 two sides of circuit board automatically, play fixation
The effect of circuit board 3 pulls fixing buckle 6 when removing circuit board 3, and fixing buckle 6 leaves the fixation hole of 3 two sides of circuit board
To take out circuit board 3.
Wherein, 2 two sides of metal top cover are equipped with bending part 21, bending part 21 and the integrated bending and molding of metal top cover 2.
A cooling fin 7 is fixed on the inside of metal top cover 2, cooling fin 7 is for circuit board 3 to be connect simultaneously with metal top cover 2
It is radiated by the metal top cover 2.
Metal top cover 2 is equipped with the venetian blind type radiator window 8 for ventilation and heat.
Implement a kind of outer casing of power supply of the utility model, there is technical effect beneficial below:
It is different from circuit board in Switching Power Supply currently on the market to be fixed by screws in Switching Power Supply shell, this technology side
Case is buckled by fixing buckle in the fixation hole of circuit board two sides, thus fixing circuit board, installation and convenient disassembly.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
