Abstract
The utility model discloses a zigzag magnet closes magnetic core with L font magnetic bodies, including a zigzag magnet and two L font magnets, the arm is rolled over to two zigzag magnets that extending direction is opposite that the zigzag magnet includes zigzag magnet straight arm and is located zigzag magnet straight arm both ends, arm mutually perpendicular is rolled over with the zigzag magnet to zigzag magnet straight arm, L font magnet includes mutually perpendicular's L font magnet straight arm and L font magnet book arm, the zigzag magnet is located between two L font magnets be equipped with the air gap between L font magnet and the zigzag magnet. The utility model discloses a coil can save the coil former directly around on the magnetic core, can practice thrift the copper product greatly, reduces resistance and copper loss and electric energy to the magnet cooling can be made, the life of product is improved.
Description
Technical field
This utility model relates to a kind of magnetic core, particularly relates to one and is mainly used in the coil such as electric ballast, transformator
The magnetic core of class inductance component.
Background technology
Traditional coil class inductance component typically by EE type magnetic core or EI type magnetic core line of engagement ring framework around upper enamel-covered wire group
Become.In order to prevent magnetic saturation phenomenon from occurring, needing to be provided with air gap in magnetic circuit, air gap is usually placed in the center pillar of magnetic core, at air gap
Due to the characteristic of magnetic circuit, there is the biggest leakage field induction in neighbouring coil, air-gap permeance is extremely low, therefore near air gap
Coil cannot participate in energy conversion, it is impossible to having no progeny in on-off control pipe pass gives off energy, and makes magnetic field reset, and can only play filling and make
With.Again because there is gap between bobbin and magnetic core, add the winding length of coil.For above-mentioned reasons, device is caused
Self copper resistance and the increase of copper loss, make the temperature of device raise, waste electric energy and copper material, reduces service life.
Utility model content
Problem to be solved in the utility model is to provide one can significantly save copper material and electric energy, reduces the Z that temperature promotes
Font magnet and L-shaped magnetic core combining.
In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that zigzag magnet and L-shaped magnet
Combined magnet core, including a zigzag magnet and two L-shaped magnets, described zigzag magnet includes zigzag magnet straight-arm and position
In the zigzag magnet folding arm that two bearing of trends at zigzag magnet straight-arm two ends are contrary, described zigzag magnet straight-arm and zigzag
Magnet folding arm is mutually perpendicular to, and described L-shaped magnet includes orthogonal L-shaped magnet straight-arm and L-shaped magnet folding arm, described
Zigzag magnet, between two L-shaped magnets, is provided with air gap between described L-shaped magnet and zigzag magnet.
Described L-shaped magnet is located at the both sides of described zigzag magnet straight-arm, and it is straight that described air gap is located at described L-shaped magnet
Between arm end face and described zigzag magnet folding arm, and described L-shaped magnet folding arm end face and described zigzag magnet straight-arm it
Between.
The cross section of described zigzag magnet is square, rectangle, circular or oval.
The cross section of described L-shaped magnet is square, rectangle, circular or oval.
The width of described air gap is 0.1～3.5mm.
Compare with the magnetic core of traditional single channel air gap, owing to this utility model is provided with multichannel air gap (four road air gaps), change
Traditional single channel gap structure, is meeting under power etc. uses and require, traditional single channel air gap needs bigger size；And this
The size of four road air gaps can be greatly reduced by utility model, can significantly reduce leakage field induction, can effectively overcome traditional
The shortcoming of magnetic core.Compare with the magnetic core of traditional single channel air gap, owing to this utility model can be carried out surface pressure-resistant treatments, coil
Can directly be wound on magnetic core, eliminate bobbin, copper material can be greatly saved, reduce resistance and copper loss and electric energy, and magnet can be made
Cooling, improves the service life of product.

Zigzag magnet folding arm 1-2 in opposite direction, described zigzag magnet straight-arm 1-1 are mutually perpendicular to zigzag magnet folding arm 1-2, institute
State L-shaped magnet 2 and include orthogonal L-shaped magnet straight-arm 2-1 and L-shaped magnet folding arm 2-2, described zigzag magnet 1
Between two L-shaped magnets 2, the folding arm termination of the straight-arm end face of L-shaped magnet and zigzag magnet is near, L-shaped magnet straight
Arm end face is near with the straight-arm termination of zigzag magnet, is provided with air gap between described L-shaped magnet 2 and zigzag magnet 1.
Described L-shaped magnet 2 is located at the both sides of described zigzag magnet straight-arm 1-1, and described air gap A, B, C, D are located at described L
Between font magnet straight-arm 2-1 end face and described zigzag magnet folding arm 1-2, and described L-shaped magnet folding arm 2-2 end face with
Between described zigzag magnet straight-arm 1-1.Label P in Fig. 1 represents that coil, coil are wound on zigzag magnet straight-arm 1-1.
Zigzag magnet of the present utility model and the width dimensions of the shape of cross section of L-shaped magnet, dimensions and air gap
Can design and produce according to actual operation requirements.Optionally, the cross section of described zigzag magnet 1 is square, rectangle, circle
