Description

A kind of combined inductor

Technical field

A kind of combined inductor 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 also conveniently combined inductor.

To achieve these goals, a kind of combined inductor of the utility model, includes the pedestal and base of resin material Flap plate, flatwise coil, the pedestal are square, and the pedestal cover plate lid is on the pedestal；The flatwise coil includes position First coil in the annular plate-like of most last layer, the second coil of annular plate-like positioned at basecoat, positioned at the First Line The tertiary coil of some annular plate-likes between circle and the second coil；The first coil, the second coil, tertiary coil wrap respectively Include four edges, and wherein a line is conductor side, in addition three while for insulator while；Conductor side in the first coil On be provided with the first extension plate portion, the second extension plate portion is provided with the conductor side of second coil；The first coil, Some tertiary coils, the second coil stack successively, and some conductor sides join end to end so as to form spiral escalation Current channel.

Square iron core is provided with the pedestal, is coated with insulating coating on the outside of iron core, the flatwise coil is sleeved on Outside the iron core.

Using above-mentioned technical proposal, the combined inductor of the utility model, since flatwise coil is used by separate First coil, the second coil and some tertiary coil stacking splicings composition, therefore can be easily by first coil, the Two coil and tertiary coil are processed as having certain thickness annular plate-like, so as to bear compared with heavy current, electric current can be with during use Extend plate portion from first as terminals to enter, and successively flow into the conductor side of some tertiary coils, finally extend from second Plate portion flows out.This splicing construction installation is very simple at the same time, more can efficiently and rapidly carry out the assembling of inductor.
