Abstract
The utility model discloses a manganese-zinc ferrite core which comprises a rectangular magnetic core bottom plate part, a pair of arc-shaped lateral columns protruding from the bottom plate part, and a central column protruding from the center of the bottom plate part, wherein the middle part of the central column is in a rectangle, and the two ends of the central column are in semicircles; and the lateral columns are arranged around the central column. After the central column with a rectangular middle part and two semicircular ends is adopted, the loss of the core, the leakage inductance, the shape distortion factors of the core can be reduced, and the noise and the outside interference are reduced; and compared with the conventional transformer made of an EP-type core, a transformer made of the manganese-zinc ferrite core has the total harmonic distortion reduced by db, so that the signal transmission distance is prolonged, the transmission speed is accelerated, and the work stability of the transformer can be improved.
Description
Technical field
The utility model relates to a kind of FERRITE CORE, particularly relates to a kind of manganese-zinc ferrite core that is used for transformer.
Background technology
In manufacturing process, FERRITE CORE is one of core material of producing by transformer, and in circuit board, leakage field is little, leakage inductance is little, noise is low, the few device of heating is a preferred orientations always.It is cylindrical-shaped structure that existing magnetic core adopts newel often, because the structure that relates to is very unreasonable, in practical application, can not get using the most widely.Magnetic core with low-loss, low total harmonic distortion is the prerequisite that transformer carries out two-forty, the transmission of high-fidelity signal, therefore needs the design optimization magnetic core, selects core loss, magnetic core distortion factor and the little magnetic core of the shape distortion factor.
Summary of the invention
To the deficiency of prior art, the purpose of the utility model is that the manganese-zinc ferrite core that a kind of leakage field is little, core loss is low is provided.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of manganese-zinc ferrite core; Comprise rectangular magnetic core base plate, from the outstanding a pair of arc lateral column of base plate and from the base plate center outstanding newel; The middle part of said newel is a rectangle, and two ends are semicircle, and said lateral column is around the newel setting.
Aforesaid manganese-zinc ferrite core is characterized in that: described lateral column is two symmetries, and is separately middle, forms cannelure between lateral column and the newel.
Aforesaid manganese-zinc ferrite core is characterized in that: an end of described lateral column aligns with the rectangle base plate, and the other end stretches out the rectangle base plate.
Compared with prior art, the utility model has the advantages that: adopt the middle part to be rectangle, two ends are semicircular newel; Core loss, leakage inductance, core shapes distortion factor have been reduced; Reduced noise and interference to external world, the low several db of transformer total harmonic distortion that the transformer of selecting this magnetic core to make is made than conventional EP type magnetic core have prolonged signal transmission distance; Improve transmission rate, improved the job stability of transformer.
Description of drawings
Fig. 1 is the front view of the utility model.
Embodiment
For further disclosing the technical scheme of the utility model; Now be described with reference to the accompanying drawings the execution mode of the utility model: as shown in Figure 1; A kind of manganese-zinc ferrite core, comprise rectangular magnetic core base plate 1, from the outstanding a pair of arc lateral column 2 of base plate and from the base plate center outstanding newel 3, the middle part of newel 3 is a rectangle; Two ends are semicircle, and lateral column 2 is provided with around newel 3.Lateral column 2 is two symmetries, and is separately middle, forms cannelure between lateral column 2 and the newel 3.One end of lateral column 2 aligns with rectangle base plate 1, and the other end stretches out rectangle base plate 1.
It is rectangle that the utility model adopts the middle part; Two ends are semicircular newel, have reduced core loss, leakage inductance, core shapes distortion factor, have reduced noise and interference to external world; The low several db of transformer total harmonic distortion that the transformer of selecting this magnetic core to make is made than conventional EP type magnetic core; Prolong signal transmission distance, improved transmission rate, improved the job stability of transformer.
More than, the basic design and the basic principle of the utility model have been set forth through introduction to listed execution mode.But the utility model never is limited to above-mentioned listed execution mode, and every equivalent variations, improvement of doing based on the technical scheme of the utility model reaches and deliberately become of inferior quality behavior, all should belong to the protection range of the utility model.
Claims (3)
1. manganese-zinc ferrite core; Comprise rectangular magnetic core base plate, from the outstanding a pair of arc lateral column of base plate and from the base plate center outstanding newel; It is characterized in that: the middle part of said newel is a rectangle, and two ends are semicircle, and said lateral column is around the newel setting.
