Specific embodiment
Below against attached drawing and in conjunction with preferred embodiment, the utility model is described in further detail.
Wire-wound inductor can provide high current, high inductance value；Magnetic permeability is bigger, same inductance value, and coiling is just few, and coiling is few
D.C. resistance can be reduced；Same size, coiling less can be around thick, raising electric currents.Using compared with thick copper lines coiling crepe cord
Circle, is vertically oriented screw winding at present, each circle not in the same plane, final wire-wound inductor device height compared with
Height limits miniaturization of electronic products, slimming development.In addition, the problem of inductance is uttered long and high-pitched sounds is frequently encountered in power supply design,
Essence is that the variation in magnetic field causes conductor, that is, the vibration of coil, and the frequency of vibration is just in audio range, and human ear is just
It can hear.
In view of above-mentioned deficiency, the utility model proposes the spiral inductances of plane winding, greatly reduce element height, and
And due to device be it is flat, than stronger, it is possible to reduce vibration, solve the problems, such as that inductance is uttered long and high-pitched sounds；It can also make large-current electric simultaneously
The design of sense is thinned, conducive to the miniaturization and slimming of product applied by it.Wherein an embodiment proposes the utility model
A kind of single flat roll around spiral inductance, including a drum, the drum is by sub-thread or two strands or more enamel covered wire same flat
Face inside spin winds and is formed, and two welding pins as the spiral inductance are drawn in the starting point of winding and end, described
Welding pin depainting is simultaneously tin plating；The welding pin is drawn after once bending perpendicular to the drum by the line end of winding line.
It is as shown in Figure 1 a kind of single flat roll without magnetic core around spiral inductance, the drum of the inductance is by four strands of enamel covered wires same
It winds and is formed in one plane.Fig. 1 is exemplary only, in addition to this, can also using sub-thread, two strands, three strands ... wait into
Row coiling, no matter when coiling, each circle was all in the same plane using several bursts of copper wire coilings together.This snail electricity
The drum center of sense can be as shown in Figure 1 it is hollow, a magnetic core also can be inserted, as shown in Fig. 2, with specific reference to application demand
To choose whether to need magnetic core.
In addition, the plane wound coil inductance of the utility model is also possible to bilayer, increase on element height in this way
It is less, but electric current can greatly increase.With reference to Fig. 3, a kind of double layer planar wound coil inductance, including pair of lamina drum, institute
State the double-deck drum by sub-thread or two strands or more enamel covered wire since the point of the centre of line two is respectively in a reverse direction at two
It winds and is formed in plane, two welding pins of the end of two planes winding as the spiral inductance, the welding is drawn
Foot depainting is simultaneously tin plating；The welding pin after the line end bending of winding line perpendicular to the double-deck drum by drawing.It is understood that
, the winding start point of above-mentioned two layers of the double-deck drum be previously mentioned is that " centre " of the point of centre two of copper wire is not necessarily referring to copper wire
Upper two points at center, but according to required winding length, it is arbitrarily chosen on the position further from line end
Why two points with certain intervals will have interval as coiling starting point, be because copper wire has certain radial ruler
It is very little, to adapt to drum thickness.When coiling, the coiling since two points are respectively is one of to put helically coiling in a clockwise direction,
Another point starts helically coiling in a counterclockwise direction, to form double layer planar spiral inductance for example shown in Fig. 3.It is this double
The drum center of layer plane spiral inductance can be as shown in Figure 3 it is hollow, a magnetic core also can be inserted, as shown in figure 4, specifically
It is chosen whether to need magnetic core according to application demand.
In a preferred embodiment, as shown in figure 3, two welding pins of the spiral inductance of double layer planar winding distinguish position
In the opposite sides side of the double-deck drum.
In short, the plane wound coil inductance of the aforementioned offer of the utility model, with existing vertical three-dimensional wound coil electricity
Sense is compared, and in same current, element height can greatly reduce；When being welded in circuit, the stability of device is more preferable, can
The inductance for avoiding in use is uttered long and high-pitched sounds problem.The plane wound coil inductance of the utility model, is especially suitable for doing high current
Inductance, be applied to industrial control mainboard, laptop, mobile unit, distribution power-supply system, DC/DC converter, LED drive power,
Communication apparatus, Medical Devices, military project electronics, Space Science and Technology etc..
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For those skilled in the art of the present invention
For, without departing from the concept of the premise utility, several equivalent substitute or obvious modifications, and performance can also be made
Or purposes is identical, all shall be regarded as belonging to the protection scope of the utility model.
