Description
Technical field
A kind of stacked inductor of high current is the utility model is related to, belongs to electronic component technology field.
Background technology
Inductor (Inductor) is also known as choke, reactor, dynamic reactor, inductance, is that electric energy can be converted into
Magnetic energy and the element stored.The structure of inductor is similar to transformer, and there is usually one winding.Inductor has certain
Inductance, it only hinder electric current change, if inductor in no electric current in the state of, circuit connect when it will attempt
Electric current is hindered to flow through it；If inductor is having electric current in the state of, it will attempt to maintain electric current constant when circuit disconnects.
Inductor is generally made of skeleton, winding, shielding case, encapsulating material, magnetic core or iron core etc..Skeleton refers to coiling line
The stent of circle.Larger fixed inductor or the adjustable electric sensor (such as oscillator coil, choking coil) of some volumes is most of
It is that enameled wire (or cotton-covered wire) is looped around on skeleton, then magnetic core or the copper heart, iron core etc. is loaded to the inner cavity of skeleton, improves it
Inductance value.Skeleton is typically to be made of plastics, bakelite, ceramics, and different shapes can be made according to being actually needed.Small electrical
Enameled wire is directly wound on magnetic core by sensor (such as inductor with colour codes) generally without using skeleton.Air-core inductor is (also referred to as
Tread flaking coil or air core coil, are chiefly used in high-frequency circuit) do not have to magnetic core, skeleton and shielding case etc., but first on mould around
Slough mould after good again, and by coil respectively enclose between pull open certain distance.Winding refers to one group of coil with predetermined function, it
It is the element of inductor.Winding has individual layer and point of multilayer.Single-layer Windings have close around (circle of conducting wire one suffers during coiling again
One circle) and two kinds of forms of spaced winding (often being enclosed during coiling between conducting wire every a certain distance)；Multi-layer winding have layering it is flat around, disorderly
It is a variety of around, universal winding etc..Magnetic core is with bar magnet generally using nickel-zinc ferrite (NX series) or manganese-zinc ferrite (MX series)
Deng material, it has the various shapes such as I-shaped, cylindricality, hat shape, E shapes, tank shape.Core material mainly has silicon steel sheet, permalloy
Deng its shape is mostly E types.Shielding case is to avoid the magnetic field that some inductors produce at work from influencing other circuits and first device
Part works normally, and is just to which increase metal screen overlay (such as oscillator coil of transistor radio etc.).Using shielding case
Inductor, can increase the loss of coil, make the reduction of Q values.Some inductors (such as inductor with colour codes, colour loop inductance device) are around making
Afterwards, coil and magnetic core etc. are sealed with encapsulating material.Encapsulating material is using plastics or epoxy resin etc..It is as shown in Figure 1
Relatively common inductor structure in the prior art, the inductor include iron core 20 and coil 30.For another example Chinese patent literature
CN1162880C discloses a kind of ultra-thin inductor, and as shown in Figure 2,3, which includes iron core base 200, iron core lid
Plate 100, flatwise coil 300, flatwise coil 300 have first end 310 and second end 320, are set in iron core base 200 fluted
210, flatwise coil 300 is located in the groove 210.In this inductor, flatwise coil 300 is in order to loading stronger electricity
Stream, then the thickness of conducting wire necessarily increases in coil, and the increase of conductor thickness can cause the difficulty that coil is processed, it is therefore necessary to
The structure of coil is improved, is splice type by coil design, so that the defects of overcoming processing difficulties.
Utility model content
Therefore, the purpose of the utility model is to overcome in the prior art the defects of, there is provided a kind of flatwise coil structure is
Splice type, so as to effectively reduce difficulty of processing, and installs the also conveniently stacked inductor of high current.
To achieve these goals, the stacked inductor of a kind of high current of the utility model, includes the base of resin material
Seat and pedestal cover board, flatwise coil, the pedestal cover plate lid are provided with circular iron on the pedestal in the pedestal
Core, iron core outside are coated with insulating coating, and the flatwise coil is sleeved on the iron core；The flatwise coil is included positioned at most upper
Layer the first terminal plate, positioned at undermost second terminal plate and between first terminal plate and the second terminal plate
Some circular conductive plates, are provided with an insulating gaps, in the upper surface of the conductive plate simultaneously on each conductive plate
The side of the insulating gaps is provided with a concave part, in the lower face of the conductive plate and positioned at the insulating gaps
Opposite side is provided with a connecting portion for being used to be inserted into the concave part of another conductive plate；In the lower section of each conductive plate also
Be provided with a circular insulating trip, be provided with the insulating trip one be used for resigning breach that the connecting portion passes through and
One protrusion for being inserted into the insulating gaps；It is connected between some conductive plates by connecting portion with concave part so as to shape
Into the current channel of spiral escalation.
In the connection that the lower face of first terminal plate is also equipped with being inserted into the concave part of the conductive plate
Portion.
The concave part that can be inserted into by the connecting portion of the conductive plate is also equipped with the upper surface of second terminal plate.
Using above-mentioned technical proposal, the stacked inductor of high current of the utility model, since flatwise coil is used by phase
The mutually structure of independent the first terminal plate, the second terminal plate and some conductive plates and insulation board stacking splicing composition, therefore energy
Enough is easily with certain thickness, so as to bear stronger by the first terminal plate, the second terminal plate and some conductive plates
Electric current, electric current and can successively flow into some conductive plates from the first terminal plate entrance as terminals when using, finally from the
Two terminal plates flow out.This splicing construction installation is very simple at the same time, more can efficiently and rapidly carry out the assembling of inductor.
