Description

A kind of inductance coil and inductor

Technical field

The utility model is related to a kind of inductance coil and inductors, belong 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 windings.Inductor has certain Inductance, it only hinder electric current variation, if inductor in the state that no electric current passes through, circuit connect when it will attempt Electric current is hindered to flow through it；If inductor, in the state of having electric current to pass through, 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 holder of circle.The larger fixed inductor of some volumes or adjustable electric sensor (such as oscillator coil, choking coil), it is most of It is enameled wire (or cotton-covered wire) to be looped around on skeleton, then magnetic core or the copper heart, iron core etc. are packed into the inner cavity of skeleton, to improve it Inductance value.Skeleton is typically to be made of plastics, bakelite, ceramics, and different shapes can be made according to actual needs.Small electrical Sensor (such as inductor with colour codes) does not use skeleton generally, but directly enameled wire is wound on magnetic core.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 mold around Slough mold after good again, and by coil respectively enclose between pull open certain distance.Winding refers to one group of coil for having predetermined function, it It is the element of inductor.Winding is divided into single layer and multilayer.Single-layer Windings have close around (circle of conducting wire one suffers when coiling again One circle) and two kinds of forms of spaced winding (often being enclosed when 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 generally uses nickel-zinc ferrite (NX series) or manganese-zinc ferrite (MX series) with bar magnet Equal materials, 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 shape is mostly E types.Shielding case is to avoid the magnetic field that some inductors generate at work from influencing other circuits and first device Part works normally, just for which increase metal screen overlay (such as oscillator coils etc. of transistor radio).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, and setting is fluted in iron core base 200 210, 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 Coil design is splice type, to overcome the defect of processing difficulties by the structure for improving coil.

Utility model content

Therefore, the purpose of the utility model is to overcome defects in the prior art, provide a kind of inductor wire of splice type Circle and the inductor with the inductance coil to effectively reduce difficulty of processing, and are installed also more convenient.

To achieve the goals above, a kind of inductance coil of the utility model, including it is the iron core bracket of resin material, embedded In iron core bracket inner-core and it is several substantially be in gate metallic plate, the metallic plate include lateral piece, be located at lateral piece The riser portion at both ends and the horizontal curved folding part being arranged in the bottom end in each riser portion, are arranged on the horizontal curved folding part The curved portion to arch upward on oriented；The main part and the base plate below main part that the iron core bracket includes rectangular-shape, Several slots that can be inserted into straight down for the metallic plate are offered on the lateral wall of the main part, each described The lower end of slot is provided with the limiting slot that can be pushed into the horizontal curved folding part, the height of the limiting slot and the metallic plate Thickness it is identical, and the upper surface of the limiting slot is provided with arc groove corresponding with the curved portion；In the master Body portion is fixed to each other with the base plate and is clamped with the first terminal plate, the second terminal plate and several connections therebetween The both ends of plate, each connecting plate are used to be connected to the horizontal curved folding part of two adjacent metallic plates, several described to make Metallic plate joins end to end to form spiral helicine conductive path by connecting plate.

First terminal plate and the second terminal plate are connected separately with the first binding post and the second binding post, and described first connects Terminal and the second binding post pass through the through-hole in the base plate.

It is offered in the bottom face of the main part for accommodating first terminal plate and the second terminal plate and connecting The holding tank of plate.

The utility model also provides a kind of inductor, including upper cover and foregoing inductance coil.

Using above-mentioned technical proposal, the inductance coil and inductor of the utility model, since inductance coil is by mutual indepedent Gate metallic plate splicing composition, therefore easily metallic plate and connecting plate can be processed as having certain thick Degree, to bear compared with heavy current, electric current can enter from the first terminal plate when use, and flow into several metallic plates one by one, finally It is flowed out from the second terminal plate.This splicing construction installation is very simple simultaneously, more can efficiently and rapidly carry out inductor Metal upright is inserted downwardly into slot by assembling, when installation, when being inserted into slot bottom end, is applied to limiting slot side and is pushed away Power makes metallic plate integrally move forward, to make horizontal curved folding part be inserted into the limiting slot, since limiting slot includes being located at The arc groove on its top, therefore horizontal curved folding part is pushed into rear arc portion in limiting slot and just corresponds to and enters in arc groove, makes gold Belong to plate to be stuck, will not fall off.
