Description
Technical field
The present invention relates to inductance, more particularly to PFC inductance.
Background technology
At present, the popularization with electronic product in life, the demand to inductance is also increasing, and small-power at present
Inductor substantially can realize automated production, and powerful inductance is substantially or with craft, and tooling device is auxiliary
Help based on production, therefore there is low production efficiency, cost of labor is high, and human factor influences the situation of product quality.
The content of the invention
It is high-power that the technical problems to be solved by the invention are just to provide a kind of combined type PFC for facilitating automated production
Inductance.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：A kind of combined type PFC inductance, including two pieces
It is be arranged in parallel above and below first magnetic core, two piece of second magnetic core and two coil windings, two piece of first magnetic core, described two piece
Two magnetic cores are side by side between two piece of first magnetic core and positioned at the length both sides of the first magnetic core, the end face of second magnetic core and the
One magnetic core is viscous and fixed, and the coil windings are nested on the second magnetic core, and the coil windings are formed using flat wire coiling.
It is preferred that, first magnetic core is class elliptic cylindrical.
It is preferred that, second magnetic core is cylinder.
It is preferred that, described two coil windings are connected by the way of serial or parallel connection
The present invention is using the magnetic core of combining structure, and two piece of second magnetic core is first and one of first magnetic core is viscous and fixed, so
It is put into afterwards on the second magnetic core around the coil windings made, finally installs other one piece of first magnetic core, not only solve inductance
The manufacture difficulty of this main process of coiling, improves production efficiency in device manufacturing process.And because the first magnetic core is class
Elliptic cylindrical, compared with original cylinder, aspect of performance is greatly improved compared with existing product, meets product raising property
Can, production efficiency is improved, reduces manually, reduces the requirement of cost.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and detailed description：
Fig. 1 is the structural representation of the first magnetic core；
Fig. 2 is the structural representation of the second magnetic core；
Fig. 3 is the structural representation of coil windings.
Embodiment
As shown in Figure 1 to Figure 3, a kind of combined type PFC inductance, including two piece of first magnetic core 1, two piece of second magnetic core 2 and
It is be arranged in parallel above and below two coil windings 3, two piece of first magnetic core, two piece of second magnetic core is side by side located at two piece of first magnetic
Between core and positioned at the length both sides of the first magnetic core, the end face and the first magnetic core of second magnetic core are viscous and fixed, the coil
Winding is nested on the second magnetic core.Two piece of second magnetic core is first viscous and fixed with one of first magnetic core, then in the second magnetic core
On be put into around the coil windings made, finally glue and install other one piece of first magnetic core, coil windings can in advance around making,
Solve the manufacture difficulty of this main process of coiling in inductor manufacturing process.In addition, coil windings using flat wire around
System is formed, and flat wire can be on the coiling machine of improvement first around making, and winding efficiency is high, and winding is unanimously good.Using common round wires around
Winding efficiency processed is slow, and easily hinders line, and quality is unstable.The inductance of existing use flat wire is by the magnet ring cutting of finished product
Piece is cut, and there is cutting sheet the magnet ring after certain thickness, therefore cutting to be no longer circular in itself, reduce the space of coiling,
And magnet ring fraction defective is higher during cutting, cutting speed is slower, and semicircle magnet ring connection is difficult, and cost is higher.The present invention is used
The magnetic core assembling mode simply shaped, solving original magnetic core needs to cut or can not use flat wire as the situation of winding,
And form forming magnetic core simple in construction is convenient, percent defective is low, there is certain advantage in price.
Wherein, first magnetic core is class elliptic cylindrical, and cylinder section configuration is by two parallel straightways and connection two
The circular arc line segment composition of Line Segment end points.Compared with original cylinder, aspect of performance has significantly compared with existing product
Improve.
In addition, described two coil windings can be connected according to the difference of electric current by the way of serial or parallel connection.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, and is familiar with
The those skilled in the art should be understood that the present invention includes but is not limited to accompanying drawing and interior described in embodiment above
Hold.The modification of any function and structure principle without departing from the present invention is intended to be included in the scope of claims.
