Abstract
The invention discloses a totally-enclosed split type powder metallurgy soft magnetic tank which is characterized by comprising base plates, a plurality of laminated circular magnetic ring shield walls and a magnetic core, wherein the laminated circular magnetic ring shield walls are installed between the two base plates; the magnetic core is formed by laminating a plurality of cylinder bodies; the magnetic core is fixed to central shafts of the magnetic ring shield walls; winding spaces are formed between the magnetic ring shield walls and the magnetic core; the center of the magnetic core is provided with a fixed hole; a bolt penetrates through the fixed hole for fixing the magnetic core to the two base plates; and line outlet grooves are arranged on the base plates or the magnetic ring shield walls. The totally-enclosed split type powder metallurgy soft magnetic tank can solve the technical problem that the electromagnetic compatibility and the magnetic leakage flux can not be guaranteed because a coil is exposed out of a magnet by winding the coil on a circular iron powder core or a square split iron core in the prior art.
Description
Technical field
The present invention relates to the manufacturing technology of electric equipment products such as a kind of reactor, transformer, specifically belong to powder metallurgy soft magnetism tank body production technology.
Background technology
At present; In the production of powder metallurgy soft magnetic-powder core inductor and transformer; Prior art is at materials such as the ferrocart core of annular or square assembly unit, iron sial, iron nickel molybdenum or iron nickel 50 composition and coils that coil exposes outside magnet, can't ensure Electro Magnetic Compatibility and leakage field size.Since product can not with keep certain electric insulation distance all around, so this inductor and transformer can't use in big capacity and occasion that leakage field is had higher requirements, only can be applied to high frequency precision circuit and low power electric power, electron trade.
Summary of the invention
The purpose of this invention is to provide a kind of totally-enclosed split mounting type powder metallurgy soft magnetism tank body; Coil to solve on traditional ferrocart core or square assembly unit iron core at annular; Coil exposes outside magnet, can't ensure the technical problem of Electro Magnetic Compatibility and leakage field size.
The present invention realizes the foregoing invention purpose through following technical scheme:
A kind of totally-enclosed split mounting type powder metallurgy soft magnetism tank body is formed the magnetic jar by base plate, magnet ring barrier shield, magnetic core, and the magnet ring barrier shield is circular for several stacks; Be installed between two base plates, magnetic core is made up of several cylinder stacks, and magnetic core is fixed on the central axis of magnet ring barrier shield; Form winding space between magnet ring barrier shield and the magnetic core; Magnetic core central authorities are provided with fixing hole, have a bolt to pass fixing hole magnetic core is fixed on two base plates, on base plate or magnet ring barrier shield, have out wire casing.
Said base plate is the semicircle disk-like structure.
The present invention can be according to the product that need form different capabilities through the quantity that increases or reduce shell magnet ring and inner magnet post of reality owing to having adopted erection method.Thereby through increase pad between the assembly unit part can change gap size between the magnetic parts change the tank body magnetic permeability, also can be through the adjustment binding material the adjustment of characteristic of characteristic, soft magnetic material change reaching this purpose, thereby be implemented in the product of assembling out the different technologies performance under the condition that does not change overall dimension.The soft magnetism jar of this product has characteristics such as volume is little, loss is little, noise is little, uses appropriate Magnaglo and suitable technology, and the anti-high frequency performance of product can be up to 100kHz.Owing to adopt the assembling process of part, reduced the size of single part, can use little tonnage forcing press to make a parts, save equipment input cost and material cost etc.
The tank body of this product adopts the assembly unit of no gap and adopts epoxide-resin glue to annotate technique for fixing, and big, the high temperature resistant thermal endurance class that reaches 220 ℃ of adhesion strength is applicable to the manufacturing of H level reactor and power transformer product.It has only the totally-enclosed pot type structure of outlet opening, makes to realize effects such as little leakage field, low-loss and compact structure with reactor, the transformer of its manufacturing.
Description of drawings
Fig. 1 is an internal structure sketch map of the present invention.
Fig. 2 is a front view of the present invention.
Embodiment
The present invention adopts soft magnetic material to process three kinds of parts of ring-type, half plate-like and column form, adopts erection method to use magnetic-conductive adhesive to be bonded to pot type above-mentioned part.Annular element is used to form shell, and the column part is used to form inner core, and half discoid part is formed the upper and lower bottom plate of product.The shell of this tank body be the guard shield of this product also be magnetic circuit, constitute product casing with the magnetic post and the upper and lower bottom plate of inside, thereby form an enclosed magnetic loop.This tank body is a totally enclosed tank body except that line outlet, thereby has reduced the possibility of leakage field to greatest extent.
Concrete structure is referring to Fig. 1, shown in 2.Can know that by Fig. 1,2 this magnetic tank body is made up of magnetic core 3, magnet ring barrier shield 2, upper and lower base plate 1,5.Its middle magnetic ring barrier shield 2 is circular for several stacks, and upper and lower base plate 1,5 is the semicircle disk-like structure, and magnetic core 3 constitutes for several cylinder stacks.Magnet ring barrier shield 2 all adopts segmentation structure with magnetic core 3, can freely adjust height and adjust with design capacity.
When the present invention makes up; Through magnetic core 3 two ends are engaged with upper and lower bottom plate 1,5, and through magnetic core 3 as interfix, guaranteeing not can displacement; Again magnet ring barrier shield 2 is enclosed within on the magnetic core 3; Magnet ring barrier shield 2 is bonded together with upper and lower base plate 1,5, and fixing hole 4 is passed with integral locking through bolt 6 after installing coil in inside, and magnetic core 3 can freely be adjusted height with magnet ring barrier shield 2.
With magnet ring barrier shield 2, carry out involutory covering up and down with two upper and lower base plates 1,5, leading-out terminal leaves out wire casing 7.There are two kinds of outlet methods optional, last outlet or side outlet.Draw outlet terminal through going out wire casing 7, put on bolt 64 li of fixing holes then the magnetic jar is tightened to one, at the magnet ring barrier shield 2 inner colloids of filling, be used to make soft magnetism jar magnetic conductive loop reactor or power transformer product again with insulating property (properties).
