Abstract
The utility model belongs to powder core appliance technology more particularly to a kind of soft magnetic metal powder core.The utility model discloses a kind of soft magnetic metal powder core, including bottom plate, center pillar and side leg are provided on the bottom plate, between side leg and center pillar composition can accommodate coil around linear window.The utility model has the beneficial effects that：Effective shielding leakage field, leakage inductance so that core structure is compact, Electro Magnetic Compatibility is good, electromagnetic interference is small, production efficiency is high, not only improves volume production efficiency, but also saved equipment cost and the expenditure of supplies, while greatly reducing cost of labor.
Description
Technical field
The utility model belongs to powder core appliance technology more particularly to a kind of soft magnetic metal powder core.
Background technology
Metal soft magnetic powder core material be a kind of widely used, yield reach, the base of electronics industry at low cost and several points industry
Plinth material, is its important one of pillar product, his application directly affect electronic information, household electrical appliances industry, computer and communication,
Environmental protection and the development of power-saving technology.E-type magnetic core is open type shell, generates larger leakage field in application, interferes on circuit board
Other electron component.
Invention content
Utility model aims to solve techniques discussed above problems, provide the effective shielding leakage field of one kind, leakage
Sense so that core structure is compact, Electro Magnetic Compatibility is good, electromagnetic interference is small, production efficiency is high, not only improves volume production efficiency, and
And equipment cost and the expenditure of supplies have been saved, while the soft magnetic metal powder core of cost of labor is greatly reduced,
Technical solution is as follows：
A kind of soft magnetic metal powder core, which is characterized in that including bottom plate, center pillar and side leg are provided on the bottom plate,
Between side leg and center pillar composition can accommodate coil around linear window.
Preferred embodiment is, the center pillar is cylinder, and center pillar is arranged the opening in bottom plate, the external arc of center pillar with open
Distance at mouthful is more than or equal to Inner arc at a distance from the leg of side.
Preferred embodiment is that the side leg is the shape of a hoof, and horseshoe-shaped side leg outer side is right angle chamfering or circular arc chamfering.
Soft magnetic metal powder core provided by the utility model, when in use, by the way that semi-surrounding is arranged on bottom plate
The pin connector of coil is placed on the opening of bottom plate by side leg when being assembled with coil, which had both ensured the side leg of magnetic core
With enough magnetic conductive areas, and the useful space of magnetic core is taken full advantage of, improve the efficiency of product, keeps core structure tighter
It gathers, in addition, coil is surrounded by side leg and bottom surface multi-panel, the Electro Magnetic Compatibility of product is good, and electromagnetic interference very little is generated to the external world,
On the other hand the anti-interference ability of itself is also improved.Preferably, the side leg horseshoe type chamfering of the magnetic core can fall for circular arc type
Angle not only improves volume production efficiency, but also has saved equipment cost and the expenditure of supplies, while greatly reducing artificial
Cost, to improve the competitiveness of enterprise.
The utility model has the beneficial effects that：Effective shielding leakage field, leakage inductance so that core structure is compact, electromagnetic compatibility
Property it is good, electromagnetic interference is small, production efficiency is high, not only improve volume production efficiency, but also saved equipment cost and supplies
Expenditure, while greatly reducing cost of labor.

Specific implementation mode
With reference to Fig. 1 to Fig. 4 specific illustrative embodiment：
A kind of soft magnetic metal powder core, including bottom plate 4, are provided with center pillar 3 and side leg 1 on the bottom plate 4, side leg 1 with
Between center pillar 3 composition can accommodate coil around linear window 2.
Preferred embodiment is, the center pillar is cylinder, and center pillar is arranged the opening in bottom plate, the external arc of center pillar with open
Distance at mouthful is more than or equal to Inner arc at a distance from the leg of side.
Preferred embodiment is that the side leg is the shape of a hoof, and horseshoe-shaped side leg outer side is right angle chamfering or circular arc chamfering.
The requirement of coiling window size：In Fig. 2, width is more than or equal to width at 6 at 5, ensures that magnetic core bottom plate is completely covered
Firmly coil avoids leakage field.Sectional area is more than or equal to sectional area at 1.05 times 22 at 21, and magnetic permeability is lower, area at 21
With 22 at area ratio should be bigger, more effective shielding leakage field, leakage inductance.
When being assembled with coil, the pin connector of coil is placed on 4 opening of bottom plate, which had both ensured the side of magnetic core
Leg has enough magnetic conductive areas, and takes full advantage of the useful space of magnetic core, improves the efficiency of product, makes core structure more
It is compact.Two magnetic core mating surfaces are bonded together when use, and coil is surrounded by side leg 1 and bottom plate 4 and 3 multi-panel of center pillar, at this moment
The Electro Magnetic Compatibility of product is good, generates electromagnetic interference very little to the external world, on the other hand also improves the anti-interference ability of itself.
