The circuit board in the switching power supply refers to a circuit structure formed by inserting various electronic elements in the switching power supply, such as the power grid filter, the input rectifying filter, the inverter, the output rectifying filter, the capacitor and the like, on a PCB and mutually connecting the electronic elements through a circuit on the PCB. The circuit board in the switching power supply is used for being connected with an external power supply and electric equipment so as to convert the voltage of the external power supply into the voltage required by the electric equipment.
If the number of electronic components in the switching power supply is large, the volume of the PCB is also increased, so that a sufficient space is provided for mounting the large number of electronic components. And the volume of the PCB is increased, so that the volume of the switching power supply is increased, and the miniaturization and microminiaturization development of the electrical equipment are not facilitated.
Based on this, referring to fig. 1, fig. 1 shows a schematic structural diagram of a switching power supply according to some embodiments of the present utility model, and the switching power supply according to an embodiment of the present utility model includes a main circuit board 10, a secondary circuit board 20, and electronic components, where the electronic components may be the above-mentioned power grid filter, the input rectifying filter, the inverter, the output rectifying filter, the capacitor, and so on.
The secondary circuit board 20 is mounted on the main circuit board 10 and is disposed at an angle with the main circuit board 10, in the actual use process, the control circuit of the switching power supply can be divided into two parts, one part of the circuits, such as a driving circuit, is transferred to the secondary circuit board 20, and then the secondary circuit board 20 is fixed on the main circuit board 10 by welding or inserting, so that the volume of the main circuit board 10 is reduced, and the effect of reducing the volume of the switching power supply is achieved.
Because the secondary circuit board 20 is disposed at an angle with the main circuit board 10, when a part of electronic components are mounted on the secondary circuit board 20, the electronic components are located above the main circuit board 10, rather than being directly mounted on the surface of the PCB like in the conventional circuit board, and the electronic components are mounted above the main circuit board 10 through the secondary circuit board 20, so that the space above the main circuit board 10 can be effectively utilized, and the volume of the main circuit board 10 is reduced, thereby reducing the volume of the switching power supply.
In the practical use process, if the input voltage of the external power supply input to the switching power supply is high and the power is high, the switching power supply needs to use a large number of capacitors, and meanwhile, the volume of the capacitors needs to be increased to adapt to the high voltage and the high power input by the external power supply. When a large number of large-size capacitors are mounted on a PCB, a large amount of mounting space is occupied on the PCB, so that the size of the PCB is increased to accommodate the large number of large-size capacitors in order to avoid mutual interference between the capacitors and other electronic elements on the PCB, and the size of the PCB is increased, so that the size of the switching power supply is increased, and the miniaturization and microminiaturization development of electrical equipment are not facilitated.
Therefore, the electronic component mounted on the secondary circuit board 20 is the capacitor 30, so that the capacitor 30 is mounted above the main circuit board 10 through the secondary circuit board 20, the mounting space required by the capacitor 30 is saved, when only one capacitor 30 is mounted on the secondary circuit board 20, the capacitor 30 can be directly mounted close to the surface of the main circuit board 10, or when other electronic components are mounted on the main circuit board 10, the capacitor 30 is mounted above the electronic component through the secondary circuit board 20, the capacitor 30 is prevented from occupying the space on the side surface of the electronic component, the space above the electronic component is fully utilized, the volume of the main circuit board 10 is reduced, and the volume of the switching power supply is further reduced, so that the electronic device is suitable for miniaturization and microminiaturization.
When the plurality of capacitors 30 includes a plurality of capacitors, as shown in fig. 1, the plurality of capacitors 30 are all mounted on the secondary circuit board 20, that is, all the capacitors 30 are mounted above the primary circuit board 10, so that the mounting of the plurality of capacitors 30 can avoid occupying the mounting space of other electronic components on the primary circuit board 10, and only occupy the mounting space above the primary circuit board 10 or above other electronic components, thereby enabling the primary circuit board 10 to mount a larger number of capacitors 30. Thus, the main circuit board 10 does not need to increase the area to mount more capacitors 30, thereby reducing the volume of the main circuit board 10, and reducing the volume of the switching power supply to adapt to the miniaturization and microminiaturization of the electrical equipment.
When the capacitor 30 includes a plurality of capacitors, the space above the main circuit board 10 is larger, but when the number of capacitors 30 is larger, the overall volume of the switching power supply is still increased when the space above the main circuit board 10 is occupied, so that the plurality of capacitors 30 need to be arranged more compactly, and the volume of the switching power supply is further reduced. To this end, in some embodiments of the present utility model, the plurality of capacitors 30 are arranged in a plurality of rows sequentially along the first direction X, each row including the plurality of capacitors 30 arranged sequentially along the second direction Y, the second direction Y intersecting the first direction X. The sequential arrangement means that two adjacent capacitors 30 can be abutted against each other, or a certain gap can be formed between the adjacent capacitors, and the adjacent capacitors can be specifically selected according to the arrangement condition of the switching power supply.
Therefore, the capacitors 30 are installed in a multi-row mode, so that the capacitors 30 are installed more regularly, the capacitors 30 are installed more compactly, the installation space required by the installation of the capacitors 30 is saved, the volume of the main circuit board 10 is further reduced, the volume of the switching power supply is also reduced, and the electric equipment is miniaturized and miniaturized.
In some embodiments, the second direction Y is parallel to the longitudinal direction of the main circuit board 10, that is, each row of capacitors 30 is sequentially arranged along the longitudinal direction of the main circuit board 10, so that a row of capacitors 30 closest to the main circuit board 10 can be close to the surface of the main circuit board 10, and the row of capacitors 30 can extend against the surface of the main circuit board 10 to improve the utilization rate of the space above the main circuit board 10, so that the structure of the switching power supply is more compact and the size is smaller.
In the practical use process, the capacitor 30 is mostly a cylinder, and the end face of the capacitor 30 is provided with pins, and the pins are used for being connected with the secondary circuit board 20, so that the capacitor 30 is fixed on the secondary circuit board 20, at this time, one end of the capacitor 30 is mounted on the secondary circuit board 20, the other end extends lengthwise along the third direction Z, and the first direction X, the second direction Y and the third direction Z intersect two by two and are not coplanar. In other embodiments, the orientation of the capacitor 30 may be changed by pin-arranging, so that the capacitor 30 extends along the first direction X or along the second direction Y.
In some embodiments, all of the capacitors 30 are mounted on one side of the secondary circuit board 20 to make the mounting of the plurality of capacitors 30 more compact, while in other embodiments, a portion of the capacitors 30 may be disposed on one side of the secondary circuit board 20 and another portion of the capacitors 30 may be disposed on the other side of the secondary circuit board 20, and the specific arrangement of the capacitors 30 may be selected according to the overall arrangement of the circuit board.
In the embodiment of the utility model, the main circuit board 10 and the auxiliary circuit board 20 are vertically arranged, so that not only the installation stability of the auxiliary circuit board 20 on the main circuit board 10 can be increased, but also the capacitor 30 and the auxiliary circuit board 20 are installed on the main circuit board 10 more regularly, thereby ensuring that the layout of the switching power supply is more compact and the size is smaller.
In the embodiment of the present utility model, the secondary circuit board 20 is plugged onto the primary circuit board 10 to facilitate the installation of the secondary circuit board 20 by plugging, while in other embodiments, the secondary circuit board 20 may be installed on the primary circuit board 10 by soldering.
The embodiment of the present utility model further provides an electrical device, which includes the switching power supply in any embodiment, and when the input voltage of the external power supply to the switching power supply is high and the power is high, the switching power supply needs to use a larger number of capacitors 30, and the plurality of capacitors 30 are all mounted on the secondary circuit board 20 through the switching power supply, so as to avoid occupying the mounting space of other electronic components on the primary circuit board 10, and only occupying the mounting space above the primary circuit board 10 or above other electronic components, so that the primary circuit board 10 can mount the larger number of capacitors 30. Thus, the main circuit board 10 does not need to increase the area to mount more capacitors 30, thereby reducing the volume of the main circuit board 10, and reducing the volume of the switching power supply to adapt to the miniaturization and microminiaturization of the electrical equipment.
The switching power supply has at least the following advantages:
because the secondary circuit board 20 is disposed at an angle with the main circuit board 10, when some electronic components are mounted on the secondary circuit board 20, the electronic components are located above the main circuit board 10, rather than being directly mounted on the surface of the PCB like in the conventional circuit board, and the electronic components are mounted above the main circuit board 10 through the secondary circuit board 20, so that the space above the main circuit board 10 can be effectively utilized, and the volume of the main circuit board 10 is reduced, thereby reducing the volume of the switching power supply.
When the electronic component mounted on the secondary circuit board 20 is a capacitor, if the number of the capacitors 30 is only one, the capacitors 30 can be directly mounted close to the surface of the primary circuit board 10 when the capacitors 30 are mounted on the secondary circuit board 20, or other electronic components can be mounted on the primary circuit board 10, and the capacitors 30 are mounted above the electronic component through the secondary circuit board 20, so that the capacitors 30 occupy the space on the side of the electronic component, the space above the electronic component is fully utilized, the volume of the primary circuit board 10 is reduced, and the volume of the switching power supply is further reduced, so as to adapt to miniaturization and microminiaturization of electrical equipment.
When the plurality of capacitors 30 includes a plurality of capacitors, as shown in fig. 1, the plurality of capacitors 30 are all mounted on the secondary circuit board 20, that is, all the capacitors 30 are mounted above the primary circuit board 10, so that the mounting of the plurality of capacitors 30 can avoid occupying the mounting space of other electronic components on the primary circuit board 10, and only occupy the mounting space above the primary circuit board 10 or above other electronic components, thereby enabling the primary circuit board 10 to mount a larger number of capacitors 30. Thus, the main circuit board 10 does not need to increase the area to mount more capacitors 30, thereby reducing the volume of the main circuit board 10, and reducing the volume of the switching power supply to adapt to the miniaturization and microminiaturization of the electrical equipment.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
