Abstract
The utility model discloses a printed circuit board superposed structure for reduce electric quick-witted case structure size, the partial device of main circuit board is independently come out and is constituteed multi-functional board, and multi-functional board and main circuit board overlap the installation, separate with insulating barrier between, and the screw more than two is fixed with it with the welding metal terminal that corresponds. The printed circuit board has simple structure, convenient and fast installation and high production efficiency.
Description
Technical Field
The utility model relates to a power electronics printed circuit board's wiring technique, for further reducing the mounting structure size, the printed circuit board overlapping structure of in particular to plastics casing converter.
Background
The development of power electronic technology is focused on the development of power electronic devices, and in order to make the structure of a power electronic device compact and the volume of the power electronic device reduced, a plurality of power electronic devices and necessary auxiliary components are often made into a module form, which brings great convenience to the application. For example, a power integrated circuit integrates a driving circuit, a control circuit and a protection circuit with a power device, including a composite device IGBT, and power electronic application systems are developed in the direction of high efficiency, energy saving, miniaturization and intellectualization. Printed circuit boards are almost every electronic device in which a printed circuit board is a carrier for an integrated circuit, the integrated circuit is soldered to the printed circuit board, and high density of the printed circuit board can be developed with the increase in integration of the integrated circuit and the progress of mounting technology. In the prior art, all the components are generally mounted on a printed circuit board in a centralized manner, and the size of the frequency converter driving board is large, which results in a large structural size of the frequency converter.
Disclosure of Invention
The utility model provides a printed circuit board overlapping construction for reduce electric quick-witted case structure size.
The to-be-solved technical problem of the utility model is that the partial device of main circuit board independently comes out and constitutes multifunctional plate, and the last cloth of functional plate contains device one, device two, device three etc. and multifunctional plate overlaps the installation with main circuit board, separates with insulating barrier between, and the screw more than two is fixed with it with the welding metal terminal that corresponds.
The utility model discloses the technical problem that further solve is that the welding metal terminal welds on main circuit board.
The utility model discloses the technical problem that still further will solve lies in that the welding metal terminal is the U-shaped, and opens the screw hole of utensil and screw adaptation.
Adopt the utility model discloses a printed circuit board overlap structure changes into two with the great printed circuit board of a size, has reduced the projection size and then has reduced the installation area of electric machine case, and structural style is simple, and convenient assembling is swift, and production efficiency is high.
The printed circuit board overlapping structure of the present invention will be described in further detail with reference to the accompanying drawings.
Drawings
Fig. 1 is a perspective view of the printed circuit board overlapping structure of the present invention.
Fig. 2 is a perspective view of a solder metal terminal of the overlay structure of the printed circuit board shown in fig. 1.
Detailed Description
Fig. 1 shows a small-size moulded case converter printed circuit board overlay structure's stereogram, and the converter drive plate is promptly the utility model discloses main circuit board 1, for further reducing the converter structure size, converter main circuit board 1 size should be as little as possible, will originally install independent the coming out of partial device in converter main circuit board 1 and constitute power coprocessing multifunctional plate 3, power coprocessing multifunctional plate 3 and converter main circuit board 1 overlap the installation, reach the purpose that reduces converter structure size. The power supply co-processing multifunctional board 3 is respectively fixed on two welding metal terminals 11 of the main circuit board 1 of the frequency converter by two screws 2, and the main circuit board 1 of the frequency converter and the multifunctional board 3 are separated by an insulating partition board 4. The insulating partition plate 4 is made of a high-dielectric-strength polyester film, and the power supply co-processing multifunctional plate (4) comprises a charging module device I31, an absorption module device II 32, an EMC (electro magnetic compatibility) adjusting module device III 33 and the like.
Fig. 2 shows that the welding metal terminal 11 is in an inverted U shape, the bottom surface of which is welded on the main circuit board 1, and the top of which is provided with a threaded hole adapted to the screw 2.
The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in any way, and those skilled in the art can apply various equivalent changes and modifications based on the above embodiment, and all equivalent changes and modifications within the scope of the appended claims should be covered by the present invention.
