Abstract

The utility model discloses a ferrite core for a flat transformer, which consists of a magnetic core central post, a pair of rectangular side posts cut circularly and a bottom plate, wherein the central post is elliptic, and the central post is vertically connected in the center of the bottom plate; the side posts are vertically connected on two sides of the bottom plate; the central post and the side posts are positioned on the same lateral surface of the bottom plate; and trapezoidal grooves are processed on the bottom plate on two sides of the central post. The ferrite core is used in pair. The ferrite core has the benefits of scientific and simple structure, high practical value and suitability for large-scale production. Because the ferrite core for the flat transformer provided by the utility model has the structure consisting of the elliptic magnetic core central post, the pair of rectangular side posts cut circularly and the trapezoidal bottom plate without an upper bottom, the ferrite core has low flux leakage, low leakage inductance and low noise and also can reduce joule heat produced by circulating current.

Description

A kind of flat transformer FERRITE CORE

Technical field

The utility model relates to a kind of flat transformer FERRITE CORE.

Background technology

In the manufacturing process of reality, FERRITE CORE is one of core material of production small-power flat transformer.In circuit board, leakage field is little, and leakage inductance is little, and noise is low, and few device that generates heat is a preferred orientations always.Existing magnetic core often because the structure of design is very unreasonable, can not get using the most widely in actual applications.

The utility model content

At above defective, the utility model provides a kind of flat transformer FERRITE CORE.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of flat transformer FERRITE CORE, form by core center post, a pair of rectangle lateral column and base plate by circular cutting, the newel ovalize, newel is vertically connected on the center of base plate, lateral column is vertically connected on the both sides of base plate, newel and lateral column are positioned at the same side of base plate, are processed into dovetail groove on the base plate of the both sides of newel.

The utility model uses in pairs, and the beneficial effects of the utility model are: scientific structure is simple, and the practical value height is fit to large-scale production.The utility model provides a kind of flat transformer FERRITE CORE, and is because of its oval core center post, a pair of by the rectangle lateral column of circular cutting and the trapezoidal bottom plate structure at the supreme end, make that the magnetic core leakage field is little, leakage inductance is little, and noise is low, can also reduce the Joule heat that produces because of circulating current.

Description of drawings

Fig. 1 is the front view of a kind of flat transformer with FERRITE CORE;

Fig. 2 is the vertical view of a kind of flat transformer with FERRITE CORE.

Embodiment

According to embodiment and accompanying drawing the utility model is described in further detail below.

Shown in Fig. 1-2, a kind of flat transformer FERRITE CORE, form by core center post 1, a pair of rectangle lateral column 2 and base plate 3 by circular cutting, newel 1 ovalize, newel 1 is vertically connected on the center of base plate 3, lateral column 2 is vertically connected on the both sides of base plate 3, and newel 1 and lateral column 2 are positioned at the same side of base plate 3, is processed into dovetail groove on the both sides of newel 1 base plate 3.

The utility model uses in pairs, and the beneficial effects of the utility model are: scientific structure is simple, and the practical value height is fit to large-scale production. The utility model provides a kind of ferrite core for flat transformer, and is because of its oval core center post, a pair of by the rectangle lateral column of circular cutting and the trapezoidal bottom plate structure at the supreme end, so that the magnetic core leakage field is little, leakage inductance is little, and noise is low, can also reduce the Joule heat that produces because of circulating current.
