Description

A kind of horizontal inductor

Technical field

A kind of horizontal 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 coil assembly for splicing Type, so as to effectively reduce difficulty of processing, and installs also conveniently horizontal inductor.

To achieve these goals, a kind of horizontal inductor of the utility model, includes the shell and iron core of resin material Stent, iron core, coil assembly, the iron core bracket are square tube shape, and iron core is located on the inside of iron core bracket, and the coil assembly includes Some to be bent to be substantially in the metallic plate of gate, the metallic plate is including horizontal plate part and is connected to horizontal plate part both ends Vertical plate portion, a bending part is connected with the bottom of each vertical plate portion；It is described vertical that the bending part includes being connected to Plate portion and inwardly inclined first bending segment, and it is connected to first bending segment and inclined second curved laterally Trisection, and it is connected to the horizontal segment of second bending segment；Two vertical plate portions of the metallic plate are by the iron core bracket It is clipped in wherein, and the bending part is in the lower section of the iron core bracket；The shell include underlying supporting plate and Upper cover above supporting plate, is provided with the connection of the first terminal plate, the second terminal plate and some metals on the supporting plate Plate, the both ends of each connecting plate are used for the horizontal segment for being connected to two adjacent metal sheets, so that some gold Belong to plate to join end to end to form spiral helicine conductive path by connecting plate；The upper cover compresses the coil assembly, and passes through Screw is fixed on the supporting plate.

The groove for accommodating the vertical plate portion and horizontal plate part is provided with the iron core bracket.

The through hole being pierced by for first terminal plate and the second terminal plate is offered on the supporting plate.

Using above-mentioned technical proposal, the horizontal inductor of the utility model, since coil assembly is by mutually independent gate Metallic plate splicing composition, therefore easily metallic plate and connecting plate can be processed as with certain thickness, so as to hold By compared with heavy current, electric current can be from the first terminal plate entrance as terminals when using, and flows into some metallic plates one by one, most Flowed out afterwards from the second terminal plate.This splicing construction installation is very simple at the same time, more can efficiently and rapidly carry out inductor Assembling.
