Traditional Surface Mount power inductor all be take enamelled wire or flatwise coil as main, and complex manufacturing technology and the volume of such coil are larger, make the volume of inductor larger, and loss is high, and production efficiency is low.
Summary of the invention
Based on this, be necessary the problem for the shortcoming of prior art, a kind of novel Surface Mount power inductor is provided, reasonable in design, simple, volume is little, and production efficiency is high.
A novel Surface Mount power inductor, comprises magnetic core and is located at the paper tinsel formula winding on described magnetic core, described magnetic core comprises the first magnetic core and the second magnetic core, and described the first magnetic core is E shape, and described the second magnetic core is I shape; Described paper tinsel formula winding takes the shape of the letter U, and described paper tinsel formula winding is located at position between described the first magnetic core and the second magnetic core.
In an embodiment, the end of described paper tinsel formula winding is provided with pin therein.
In an embodiment, described paper tinsel formula winding is copper sheet therein.
In an embodiment, on described the first magnetic core, offer storage tank therein, described storage tank is for accommodating described paper tinsel formula winding.
In an embodiment, described the first magnetic core has a center pillar core therein, and the both sides of described the first magnetic core have respectively a side protuberance; Described center pillar core and side protuberance form described storage tank.
Above-mentioned novel Surface Mount power inductor, the combination of EI magnetic core, paper tinsel formula winding is tightly around between the first magnetic core and the second magnetic core, compact conformation, simple, volume is little, low-loss.Described pin independent support, is easy to welding, in actual applications, can paste other thinner SMT class device between the bottom of this inductor and circuit board, to improve space availability ratio, adapts to current electronic product development.It is single that the utility model is made material, is applicable to batch production, reduced manufacturing cost, applied widely.
Accompanying drawing explanation
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model.
Fig. 2 is structural representation of the present utility model.
Below the explanation of the utility model parts sign flag:
The first magnetic core 10, storage tank 11, center pillar core 12, side protuberance 13, the second magnetic core 20, paper tinsel formula winding 30, pin 31.
Embodiment
For further understanding feature of the present utility model, technological means and the specific purposes that reach, function, resolve advantage of the present utility model and spirit, by below in conjunction with accompanying drawing and embodiment, detailed description of the present utility model being further understood.
A novel Surface Mount power inductor, comprises magnetic core and is located at the paper tinsel formula winding 30 on magnetic core.Magnetic core comprises that the first magnetic core 10 and the second magnetic core 20, the first magnetic cores 10 are E shape, and the second magnetic core 20 is I shape.On the first magnetic core 10, offer two storage tank 11, two storage tanks 11 and be parallel to each other, for accommodating this paper tinsel formula winding 30.
The both sides that the first magnetic core 10 has center pillar core 12, the first magnetic cores 10 have respectively a side protuberance 13.Center pillar core 12 forms described storage tank 11 with side protuberance 13.The spacing distance of two storage tanks 11 is determined by size and paper tinsel formula winding 30 width of center pillar core 12.
The first magnetic core 10 becomes an integral body with the second magnetic core 20 by glue viscose, and baking is fixing.In glue, be added with spacer particle or interval adhesive tape and complete that assembling is fixing and to adjust air gap electrical, improve resistance to current characteristics, save Production Time.
This paper tinsel formula winding 30 takes the shape of the letter U, and it is located at position between the first magnetic core 10 and the second magnetic core 20.Paper tinsel formula winding 30 is made by copper sheet, on copper sheet, is coated with without slicker solder.The end of paper tinsel formula winding 30 is provided with pin 31, and the pin 31 of its end is placed in the sidepiece of the first magnetic core 10, and pin 31 protrudes from outside the first magnetic core 10.This paper tinsel formula winding 30 and the first magnetic core 10 are in one plane.
During assembling the utility model, first described paper tinsel formula winding 30 is placed in the storage tank 11 of described the first magnetic core 10, more described the second magnetic core 20 is placed on the first magnetic core 10, and fix by glue.
In sum, above-mentioned novel Surface Mount power inductor, paper tinsel formula winding 30 is tightly around between the first magnetic core 10 and the second magnetic core 20, compact conformation, simple, volume is little, low-loss.Described pin 31 independent support, are easy to welding, in actual applications, can paste other thinner SMT class device between the bottom of this inductor and circuit board, to improve space availability ratio, adapt to current electronic product development.It is single that the utility model is made material, is applicable to batch production, reduced manufacturing cost, applied widely.
When for power supply, not only volume is little, lightweight, can also reduce current ripples, reduces magnetic loss, improve power supply dynamic property, significant to performance and the power density of raising power supply.When for switching circuit, can improve efficiency and the power density of switching circuit, improve the performance of circuit, as reduce the ripple of the input and output electric current in circuit, improve the dynamic properties such as transient response speed of circuit.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
