Description
Technical field
The present invention relates to inductors technique field, in particular to a kind of pfc circuit inductor.
Background technique
Existing inductor is generally made of skeleton, winding, shielding case, encapsulating material, magnetic core or iron core etc..Rated current
As a major parameter of inductance, refer to the maximum current value that inductor can be born under the working environment of permission.It is some high
Power circuit is relatively high to the rated current requirement of inductor, therefore high-current inductor occurs.Currently, pfc circuit inductance
Device is mainly formed by " O " type sendust core+around the method coiling of enameled wire, and defect is exactly that existing pfc circuit inductor is full
It is bad with Overlay, inductor SC service ceiling is influenced, and fixation not easy to install.
Summary of the invention
For the above technical problems, the object of the present invention is to provide a kind of pfc circuit inductors, to solve
The problem of existing pfc circuit inductor saturation Overlay is bad, influences inductor SC service ceiling.
The technical scheme is that realized by following technical measures: a kind of pfc circuit inductor, including branch
Frame, coiling, iron sial piece, magnetic core and package, bracket include cylinder and the square support for being fixedly mounted on bottom of cylinder
Plate is wound with the coiling of multilayer multi-turn lap wound structure on cylinder, and the two of coiling, which lift one's head, is separately positioned on square support
The bilateral symmetry two sides of plate, the magnetic core include cylindrical type magnetic core lug boss and insulator foot, and insulator foot and pcb board, which are fixed, to be connected
It connects, iron sial piece is set to the top of magnetic core lug boss and iron sial piece and magnetic core lug boss are plugged on the inside of coiling
In cylinder, package is set on the outside of coiling and is connected on insulator foot, for protecting coiling and magnetic core.
Here is the further optimization or/and improvement to invention technology described above scheme:
Preferably, be provided with symmetrically arranged vertical block on the bottom surface of support plate, the support plate by vertical block with
Insulator foot is connected together.
Preferably, the pedestal is bakelite pedestal.
Preferably, the coiling uses enamel-cover flat copper line coil；The size of the enamel-cover flat copper line coil is 4*
2mm；The number of plies of the coiling is at least 5 layers.
Preferably, lift one's head 4 outside of the two of the coiling 2 is respectively adopted yellow cured pipe sleeve and is dielectrically separated from.
The present invention plays effective buffer action by the way that package is arranged, and can reduce exposed coil to the maximum extent, and most
The magnetic flux generated in coil is reduced to limits to external interference, to interfere to peripheral equipment.The present invention solves
The problem of existing pfc circuit inductor saturation Overlay is bad, influences inductor SC service ceiling.Pass through the electricity of iron sial piece
Sense characteristic is remarkably improved pfc circuit inductor saturation Overlay.
Detailed description of the invention
Attached drawing 1 is configuration schematic diagram of the invention.
Number in attached drawing is respectively as follows: 1, bracket, 11, cylinder, 12, support plate, 2, coiling, 3, iron sial piece, 4,
Magnetic core, 41, magnetic core lug boss, 42, insulator foot, 5, package, 6, vertical block, 7, lift one's head.
Specific embodiment
The present invention is not limited by the following example, can be determined according to the technique and scheme of the present invention with actual conditions specific
Embodiment.
Below with reference to examples and drawings, the present invention will be further described:
As shown in Figure 1, a kind of pfc circuit inductor, including bracket 1, coiling 2, iron sial piece 3, magnetic core 4 and package 5,
