Description
Technical field
The utility model relates to a kind of constructional device of circuit module, and relates more specifically to a kind of power factor correction power model constructional device.
Background technology
In the prior art, there is comparatively serious problem in power factor correction power model structural design, it mainly is to be that the circuit that will be assembled into by discrete component directly is loaded on the big base plate of heat radiation, structure so, when inserting or pulling out any composition components and parts, entire circuit all is affected, and the performance of circuit is difficult to obtain to ensure, there is mounting or dismounting inconvenience simultaneously, shortcomings such as versatility difference.
Summary of the invention
The purpose of this utility model is to provide a kind of belt substrate and independently becomes whole, simple in structure, but heat-sinking capability is strong, versatility big, the power model constructional device of easy accessibility.
The utility model is realized by following design: be fixed with a plurality of columns on a substrate, and control circuit board is anchored on the column, thereby be connected in aggregates with substrate.On control circuit board, then be provided with and form the welding hole that power device group device number equates and is complementary.The power device group then directly is anchored on the substrate, and its pin then stretches in the welding hole on the control circuit board, and thus with circuit board on circuit join.
Described substrate selects for use Heat Conduction Material to form, and is provided with the installation through hole on substrate, so that whole device can be installed on the big base plate.
Between power device group and substrate, be provided with silicone grease, also can add insulation spacer in addition.Power factor correction power model constructional device provided by the utility model, owing to be to be fixed on the substrate by a plurality of columns to constitute one, have reliable intensity and guarantee that therefore the control circuit board that is installed on the column by fastening means can obtain firm support guarantee.The power device group is owing to be directly to be anchored on the substrate, not only steadily but also firm, and substrate itself is to be made by the material with good heat conductive performance, and substrate will be directly fixed on the radiating subassembly by through hole is installed again, therefore, the power device group can obtain good radiating condition.Simultaneously, the pin of power device group then is inserted in the welding hole that is located on the control circuit board, thereby the power device group can obtain good conduction property under steadily firm prerequisite.Thereby make the utility model can realize simple in structure, the purposes such as heat-sinking capability is strong, versatility is big, easy accessibility of being scheduled to.
Description of drawings
Fig. 1 illustrates structural representation of the present utility model.
Fig. 2 illustrates the decomposition and the combination schematic diagram of the utility model structure.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, thereby make details of the present invention, characteristics, purpose and advantage clearer and more definite, but do not limited scope of the present utility model.
The structure of the utility model embodiment now is described in conjunction with the accompanying drawings: shown in accompanying drawing 1,2, a kind of power factor correction power model constructional device comprises by control circuit board 1, column 2, power device group 4 and substrate 6 and forming.Being fixed with a plurality of columns 2 on substrate 6, is a supporting surface that adopts 3 columns 2 to form in the present embodiment, when this moment, control circuit board 1 was anchored on column 2, can obtain the most stable and the ideal designs scheme.On control circuit board 1, then be provided with the welding hole 7 that equates and be complementary with the device number of forming power device group 4.
Shown in accompanying drawing 1,2, power device group 4 directly is anchored on the substrate 6, to guarantee the firm of its installation.And whole modular structure device will directly contact with radiating subassembly by substrate 6, to guarantee the effect of its heat radiation.Simultaneously, under firm prerequisite, 3 of the pins of described power device group 4 stretch in the welding hole 7 of being located at control circuit board 1, can guarantee the effect of its UNICOM after welding.
In order to ensure radiating effect, described substrate 6 is made up of Heat Conduction Material.As shown in Figure 2, on substrate 6 and be provided with 2 through holes 9 are installed.Described installation through hole 9, be to be technology through hole conveniently fastening or dismounting power device group 4, and allow whole present embodiment directly closely contact with the radiating subassembly of equipment by the good substrate 6 of heat conductivility, obtain excellent radiating effect to guarantee present embodiment.
In order further to guarantee radiating effect, between power device group 4 and substrate 6, be provided with silicone grease, guarantee heat dispersion to ensure abundant combination between the two.When not having insulating properties with substrate 6 phase-contact surfaces on the power device group 4, but then between adds insulation spacer 5 in addition, ensures its insulation between the two.
