Abstract
The utility model relates to an iron core of a mutual inductor with a fractured lamination, which comprises a core column, a left yoke, a lower yoke, a right yoke and a splint, wherein the right yoke is respectively connected with the core column and the lower yoke in an interlacing way and fixed into a whole after paint immersion; the core column, the lower yoke and the right yoke are laminated in a mutual interlacing way by adopting silicon steel sheets with different lengths; one end of the left yoke is in inverted L-shaped surface contact with one end of the core column and the other end of the left yoke is in line-shaped surface contact with one end of the lower yoke; and the left yoke is connected with the core column and the lower yoke through the right yoke to form a complete iron core body. With the adoption of the interlacing connection, good magnetic permeability is ensured; with the adoption of the cutting and grinding treatment after integral paint immersion, the evenness of the contact surface is ensured, the surface-surface contact is good, and the assembled iron core has good excitation property; with the adoption of two integral paint immersion methods after lamination assembling, the product discharge and punch-through phenomena due to the fact that the impurities such as the scrap ion enter the silicon steel sheet can be reduced.
Description
Technical field
The utility model relates to a kind of mutual inductor coil iron core, specifically a kind of band fracture type lamination transformer iron core.
Background technology
Through retrieving relevant patent documentation, not yet retrieve a kind of band fracture type lamination transformer iron core that be used for mutual inductor coil identical with the utility model structure at present.Existing mutual inductor coil iron core is generally the version of annular, is formed by stacking by blocks of silicon steel sheet is staggered; The staff need to carry out overlap-add procedure to the silicon steel sheet of slices in the production process; The closed assembly process has unavoidably iron filings and is mingled with into, causes in use discharge, the punch-through of product at last, causes scrapping of whole product; And production process takes a lot of work, time-consuming, operating efficiency is lower, so be necessary existing iron core is improved, to improve quality and the production efficiency of product.
Summary of the invention
The purpose of this utility model is that a kind of have processing, a kind of band fracture type lamination transformer iron core easy for installation will be provided.
Technical characterictic of the present utility model is: considering that processing, basis easy for installation, that magnetic property is good are designed to a kind of band fracture type lamination transformer iron core that is comprised of stem stem, left side yoke, following yoke, the right yoke, clamping plate, the right yoke is connected and in aggregates by fixing behind the dipping lacquer with stem stem, following yoke are interlaced respectively, and described stem stem, following yoke, the right yoke adopt the interlaced lamination of silicon steel sheet of different length; Yoke one end in the left side is " ┑ " face with stem stem one end and contacts, and the other end is " │ " face with following yoke one end and contacts, and is connected with stem stem, following yoke by the right yoke and forms a complete iron-core workpiece; Clamping plate are separately positioned on left side yoke, following yoke, end, yoke two sides, the right.
Described stem stem clamps the cylinder of formation for after adopting the stack of different size silicon steel sheet by bolts at two ends.
Described left side yoke is the silicon steel sheet lamination that adopts same size and an integral body that forms by dipping lacquer.
Described clamping plate are the plate body that high-strength metal material is made, and clamp both ends of the surface by bolt and form rectangle closed assembly body.
During assembling, at first with the material preparation of stem stem, the right yoke, following yoke, the form of then taking to interlock in twos superposes silicon steel sheet one by one, and clamps with bolt, forms the ring body of an opening, and the opening ring body integral body of making is carried out dipping lacquer, drying and processing; Again respectively with the stem stem in the opening ring body, following yoke in conjunction with end face and left side yoke all cut, polish processing in conjunction with end face, make its contact-making surface have good contact effect; Again coil is enclosed within on the stem stem, makes that yoke one end in the left side contacts with stem stem, the other end contacts with following yoke, and clamp by clamping plate, thereby finish whole assembling.
The utility model has the advantages that: owing to adopt the form of staggered stack to interconnect, thus guaranteed good magnetic property; Owing to be processed into the version of two integral body docking, thereby made things convenient for assembling, improved production efficiency; Owing to take that cutting polishes processing behind the whole dipping lacquer, thereby guaranteed the evenness of contact-making surface, so that face contacts well with face, make the iron core after the assembling have preferably field performance; Because iron core is taked the involutory of face and face, make the laminated core of assembling have the performance that air gap is adjusted, thereby guarantee that the iron core field performance has the preferably linearity, and effectively prevent unshakable in one's determination saturated; The method of assembling latter two whole dipping lacquer is processed owing to take to superpose, and enters product discharge, the punch-through that causes in the silicon steel sheet thereby reduced the impurity such as iron filings; Because rational in infrastructure, processing, easy for installation is so there is very large practical and popularizing value.
