Abstract

The utility model relates to a wire iron core. The utility model overcomes the defects that the thickness of an inserting disk is not uniform to affect the designed magnetic flux, a press tool is needed when the inserting disk is manufactured, the press of the inserting disk can cause the waste of materials, the electromagnetic eddy current of the inserting disk is large, and the loss is large. An iron core body is an annular structure which is formed by that a plurality of annular iron core wires are bundled into integration in a concentrated way. The cross section of the iron core body is provided with a magnetic wire sheet which can cause the iron core body to be formed into a closed loop. The cross section can be formed into circular, square, or regular hexagon, and the surface of the cross section is provided with an insulation layer. The utility model has the advantages that the fabrication is easy, the procedure of the press is removed, the waste of leftover materials is avoided in the process of pressing, the electromagnetic eddy current is small, the winding is convenient, and the iron core body with various specifications is easy to manufacture.

Description

Wire iron-core

The utility model relates to a kind of reactor, transformer etc. and has the iron core that perceptual device uses, particularly the Wire iron-core of being made by wire rod.

The iron core that uses in existing reactor, transformer is the EI type made by silicon steel sheet permeability magnetic materials such as (silicon steel sheets), C type, structure such as ring-like.The iron core of this structure is because the main magnetic conduction inserted sheet with definite shape that uses is folded slotting forming.And the magnetic conduction inserted sheet is to be made by the permeability magnetic material of silicon steel bulk thin plates such as (silicon steel).Whether gauge of sheet is even, directly influences the inserted sheet quantity of iron core, also just has influence on the magnetic flux of design.And the bulk thin plate that will make uniform thickness acquires a certain degree of difficulty.And the bulk thin plate is made the magnetic conduction inserted sheet with definite shape, not only to use diel, but also can cause the waste of sheet material.The iron core of different size will use different diels, and plurality of specifications is wanted supporting multiple diel, the manufacturing cost height.Moreover the iron core of sheet structure has certain cross-sectional area, also can produce certain eddy current, causes the loss of electric energy.

The purpose of this utility model is to provide a kind of eddy current little, and the cross section precision is controlled easily, material saving, Wire iron-core easy to manufacture.

For realizing the purpose of this utility model, the iron-core workpiece of described Wire iron-core is a loop configuration of concentrating bundle to become one by a plurality of annular core wire loops.

The drawing of accompanying drawing is described as follows:

Below in conjunction with accompanying drawing, the embodiment of the utility model Wire iron-core is described in further detail:

As shown in FIG., Wire iron-core described in the utility model, its iron-core workpiece comprise a plurality of closed annular iron core wire loops 1, and iron core wire loop 1 is to be formed by magnetic conduction wire rod coilings such as silicon steel, concentrate bundle to become one a plurality of iron core wire loops 1.This can be with the magnetic conduction wire rod coiling round and round that pulls into wire, and dipping lacquer makes between each coil to bond together mutually then.The core configuration of making can be circular, as shown in Fig. 1,2,3.Also can be square, as shown in Fig. 4,5,6.Cut at the coil section place that coiling is good, the groove of incision is changeable, and notch is big, and iron-core workpiece forms a C word shape, becomes magnetic open circuit iron core, can be used for the electric bell iron core.If notch is little, as the width of notch at 0.1～0.5 millimeter, can in notch, insert the magnetic conduction sheet 2 that adapts to thickness with it, promptly on the cross section of iron core wire loop 1, be provided with magnetic material sheet 2, with all iron core wire loop 1 short circuits, make each section magnetic conduction wire rod in magnetic material sheet 2 place's closures, form closed annular core wire loop, it is iron core-closed so just to form magnetic, and magnetic resistance is very little.Also the two sections closure after cutting like this, just can be equivalent to be provided with the seam 4 that makes it to constitute the closed-loop path on cross section, if between the iron core wire loop 1 around closely, can make in each wire loop magnetic resistance very little equally, form closed magnetic circuit.Can be used for inductance, core for transformer etc.Circular, the square or regular hexagon (showing in the drawings) of described iron core wire loop 1 Cross section Design.Be convenient to adjacent two tight closings, form densification and arrange.Described iron core wire loop 1 surface is provided with insulating barrier 3, as shown in Figure 7, makes mutually insulated between each coil, the generation of stopping electromagnetic eddy between the magnetic conduction line.

The utility model is than prior art, because the ring junction that adopts a plurality of annular core wire loops to concentrate bundle to become one Structure. Do not need diel in the manufacturing process, only need coiling. Since be wire-wound, can various sample shapes of coiled The iron-core workpiece of shape except the iron-core workpiece of said structure, can also be made such as semicircle shape, and cerioid or is as required made it The iron core of its other shaped structure. Compare the iron core of original plate-inserting structure, can save the mould of all size, reduce and make The input of equipment. Insulate between each magnetic circuit, electromagnetic eddy is little. Do not have the waste of material in the manufacture process. Has manufacturing Easily, exempt the punching operation, avoid the waste of leftover pieces in the punching process, electromagnetic eddy is little, and coiling conveniently is easy to make The advantage of the iron-core workpiece of all size.
