Description
Technical field
The application belongs to inductive technologies field, specifically, is related to a kind of PFC inductance.
Background technology
PFC English full name for " Power Factor Correction ", mean " PFC ", power because
Number refers to relations between effective power and total power consumption, that is, effective power divided by total power consumption ratio.Power because
Element can weigh the degree that electric power is used effectively, and when power factor (PF) value is bigger, represent its electric power utilization rate higher.PFC inductance
It is the inductance for pfc circuit, to improve power factor.And existing high-power PFC inductance is silicon steel sheet material, body
Long-pending big, temperature rise and the low shortcoming of efficiency；In the production process of inductance, silicon steel sheet is loaded around making in coil, to prevent
Coil is contacted and short-circuit with magnetic core, by wrapping up insulating paper on silicon steel sheet surface come retarder and silicon steel sheet, yet with exhausted
Edge paper is relatively thin, there is crackly line and splits, and can then have coil and be contacted with silicon steel sheet and the hidden danger of short circuit.
Utility model content
For deficiency of the prior art, the purpose of this utility model is to provide a kind of PFC inductance.
In order to solve the above-mentioned technical problem, this application discloses a kind of PFC inductance, it include insulator foot, lid in insulation,
Magnetic core and copper cash winding, cover to form hollow cavity wherein being covered on lid and insulator foot in insulator foot, insulation in insulation,
Magnetic core is arranged at hollow cavity, and magnetic core is that Fe-based amorphous alloy coiling is formed, and copper cash winding is wound on insulator foot and insulation
The outside of lid.
According to the embodiment of the application, lid is polybutylene terephthalate (PBT) on above-mentioned insulator foot and insulation.
According to the embodiment of the application, above-mentioned copper cash winding is by rope-lay strand coiling.
According to the embodiment of the application, the inner side covered on above-mentioned insulator foot and insulation is respectively equipped with adhesive linkage.
Compared with prior art, the application can be obtained including following technique effect：
Simple in construction, easy to assembly fast to use manpower and material resources sparingly, the raising production efficiency of the PFC inductance of the application；Simultaneously
Volume is reduced, is insulated pressure-resistant, efficiency is improved, it is safe and reliable.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding of the present application, constitutes the part of the application, this Shen
Schematic description and description please is used to explain the application, does not constitute the improper restriction to the application.In the accompanying drawings：
Fig. 1 is the explosive view of the PFC inductance of the embodiment of the application.
Fig. 2 is the sectional view of the PFC inductance of the embodiment of the application.
Embodiment
Multiple embodiments of the application, as clearly stated, the details in many practices will be disclosed with schema below
It will be explained in the following description.It should be appreciated, however, that the details in these practices is not applied to limit the application.Also
It is to say, in some embodiments of the application, the details in these practices is non-essential.In addition, for the sake of simplifying schema,
Some known usual structures will illustrate it in simply illustrative mode in the drawings with component.
On its " first " used herein, " second " etc., the meaning of order or cis-position is not especially censured, it is also non-to use
To limit the application, its component described just for the sake of difference with constructed term or operation.
Fig. 1 and Fig. 2 are referred to, it is the explosive view and sectional view of the PFC inductance of the embodiment of the application respectively；Such as
Shown in figure, the PFC inductance of the application includes lid 2, magnetic core 3 and copper cash winding 4 in insulator foot 1, insulation, wherein the upper lid 2 of insulation
It is covered on lid 2 and the conjunction of insulator foot lid 1 in insulator foot 1, insulation and forms hollow cavity, magnetic core 3 is arranged at hollow cavity, magnetic core
3 be that Fe-based amorphous alloy coiling is formed, and copper cash winding 4 is wound in the outside of insulator foot 1 and the upper lid 2 of insulation.
More specifically, the characteristic of Fe-based amorphous alloy is that magnetic is strong (saturation induction density is up to 1.4T -1.7T),
The soft magnet performances such as magnetic conductivity, exciting power and iron loss are better than silicon steel sheet, and Fe-based amorphous alloy is cheap, Fe-based amorphous alloy
Thickness of strip be generally 0.03 millimeter, by Fe-based amorphous alloy winding magnetic core is made, compared to made by silicon steel sheet
Core volume it is smaller, while workable frequency range is wider.
Further, insulator foot 1 and the upper lid 2 of insulation are molded by polybutylene terephthalate (PBT), are gathered to benzene two
The good mechanical property of formic acid butanediol ester and with excellent insulating properties, you can prevent copper cash winding from being contacted with magnetic core.
Further, copper cash winding 4 is by rope-lay strand coiling, and multi cord is closed due to it by predetermined geometric position beam
Together, numerous circumferential surfaces are formed, reach collective effect, the increase of current overload area makes alternating-current resistance decline and improve inductance
Q values.
In actual production, the inner side of insulator foot 1 and the upper lid 2 of insulation is coated respectively with epoxy glue, epoxy glue formation bonding
Layer.Magnetic core 3 is positioned in insulator foot 1 by operating personnel, and magnetic core 3 is bonded and fixed to insulator foot 1 by adhesive linkage, then covers
Lid 2 in insulation, so that magnetic core 3 is fixed in hollow cavity, prevent magnetic core 3 from being rocked in hollow cavity.
In summary, in one or more embodiments of the application, simple in construction, the assembling side of the PFC inductance of the application
Just it is quick, use manpower and material resources sparingly, improve production efficiency；Volume is reduced simultaneously, is insulated pressure-resistant, improves efficiency, it is safe and reliable.
Some preferred embodiments of the present utility model have shown and described in described above, but as previously described, it should be understood that this
Utility model is not limited to form disclosed herein, is not to be taken as the exclusion to other embodiment, and available for various
