Abstract

A novel soft magnetic ferrite core comprises a base plate, a coiling window, a middle column, and a side leg, wherein the right side of the base plate is provided with an opening, the middle column is located on the right side of the base plate, the side leg is arranged on the left side of the base plate and is arc-shaped, and the arc-shaped coiling window capable of containing a coil is formed between the side leg and the middle column. The novel soft magnetic ferrite core is compact in structure, good in electromagnetic compatibility, little in electromagnetic interference, high in production efficiency, and the like. By aid of the arrangement of the semi-enclosing side leg on the base plate, the efficient space of the magnetism core is sufficiently utilized, efficiency of the product is improved, and the structure of the magnetic core is enabled to be more compact. Further, due to the fact that a plurality of faces of the coil is enclosed by the side leg, the product is enabled to be good in electromagnetic compatibility and very little in electromagnetic interference to the outside, and self anti-jamming capability is also improved. The novel soft magnetic ferrite core not only improves production efficiency, but also saves equipment cost and expenditure for auxiliary materials, and greatly reduces manpower cost at the same time, thereby improving competitive power of enterprises.

Description

A kind of novel magnetic ferrite magnetic core

Technical field

The utility model relates to the soft magnetic ferrite field, especially relates to a kind of novel magnetic ferrite magnetic core.

Background technology

Soft magnetic ferrite is a kind of of many uses, output is large, cost is low electronics industry and the basic material of mechanotronics, it is one of its important pillar product, its application directly affects the development of electronic information, household electrical appliances industry, computer and communication, environmental protection and power-saving technology, also is one of sign of weighing the flourishing program of a national economy.Along with the miniaturization of inductance element, requirement appropriate design by shape in the situation that does not reduce its efficient makes the volume of magnetic core less.Traditional soft-magnetic ferrite core mainly is E type structure, although this type products is simple in structure, but the development along with electronic technology, the magnetic core of above-mentioned E type structure can't be applicable in the strict electronic circuit of electromagnetic environment requirements, such as notebook computer, panel computer etc., main cause is that this E type magnetic core is the open type shell, and the leakage field and the leakage inductance that produce when work are large, and other electronic component on the circuit board is produced larger interference.

Summary of the invention

The utility model purpose provides a kind of novel magnetic ferrite magnetic core.With solve the existing leakage field of prior art and leakage inductance more greatly, the technical problem such as to external world electromagnetic interference is large, core structure is not compact.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of novel magnetic ferrite magnetic core comprises base plate, coiling window, center pillar, limit leg; Described base plate right side is opening part, and center pillar is located at the base plate right side; Described limit leg is arranged at the left side of base plate, and this limit leg is arc; Form the arc-shape winding window that can hold coil between described limit leg and the center pillar.

As preferably, described center pillar is track type, and a chimb of this track type center pillar is arranged on the base plate opening part.

As preferably, described limit leg is the shape of a hoof, forms and hold the shape of a hoof coiling window of coil between this shape of a hoof limit leg and the track type center pillar.

The utlity model has the core structure compactness, Electro Magnetic Compatibility is good, electromagnetic interference is little, the production efficiency advantages of higher, by the limit leg of semi-surrounding is set above base plate, when assembling with coil, the outlet joint of coil is placed on the opening part of base plate, this design had both guaranteed that the limit leg of magnetic core had enough magnetic conductive areas, fill again part and utilized the useful space of magnetic core, improved the efficient of product, make the more compact structure of magnetic core, in addition, coil is surrounded by limit leg multiaspect, makes the Electro Magnetic Compatibility of product good, it is very little to produce to external world electromagnetic interference, has also improved on the other hand the antijamming capability of itself.Not only improved production efficiency, and saved the expenditure of equipment cost and supplies, reduced widely cost of labor simultaneously, thereby promoted the competitiveness of enterprise.

Embodiment

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.

Fig. 1 is structural representation of the present utility model; Fig. 2 is structure right view of the present utility model; Fig. 3 is stereogram of the present utility model.By Fig. 1 in conjunction with Fig. 2, Fig. 3 as can be known, a kind of novel magnetic ferrite magnetic core is mainly by base plate 4, coiling window 2, center pillar 3, limit leg 1; Described base plate 4 right sides are opening part, and center pillar 3 is located at base plate 4 right sides and is flushed with opening part; Described limit leg 1 is arranged at the left side of base plate 4, and this limit leg 1 is arc; Form the arc-shape winding window 2 that can hold coil between described limit leg 1 and the center pillar 3.

Fig. 4 is the structural representation of a kind of preferred implementation of the present utility model; Fig. 5 is the stereogram of preferred implementation shown in Figure 4.By Fig. 4 in conjunction with Fig. 5 as can be known, center pillar 31 is track type, and a chimb 310 of this track type center pillar 31 is arranged on base plate 41 opening parts.Limit leg 11 is the shape of a hoof, forms and hold the shape of a hoof coiling window 21 of coil between this shape of a hoof limit leg 11 and the track type center pillar 31.

When assembling with coil, the outlet joint of coil is placed on the opening part of base plate 4, this design had both guaranteed that the limit leg 1 of magnetic core had enough magnetic conductive areas, filled again the useful space that part has been utilized magnetic core, had improved the efficient of product, made the more compact structure of magnetic core.In addition, in the coiling window 2, the limit leg 1 of magnetic core is lived coil three bread up and down, plays the shielding protection effect because coil is packed into, in the course of the work, neither can produce and produce to external world electromagnetic interference, has improved again the antijamming capability of itself simultaneously.

The above only is preferred implementation of the present utility model; should be understood that for the person of ordinary skill of the art; without departing from the inventive concept of the premise, can also make several distortion and improvement, these also should be considered as within protection scope of the present invention.
