Abstract
The utility model relates to a kind of power factor correction inductors, belongs to technical field of electronic components.Comprise inductor body, described inductor body comprises magnet ring and winding; Described magnet ring is formed by stacking with one heart by the identical magnet ring of size and No. two magnet rings; Described winding adopts the mode of Double-wire parallel wound to be wound on magnet ring; The bottom of described inductor body is provided with pedestal; The bottom even of described pedestal is provided with several pins; Each lead end of described winding is welded and fixed with each pin respectively.The utility model adopts two magnet ring superposition coiling, can reduce the volume of whole product, and increase magnetic core saturation flux density and net sectional area increase, inductive factor doubles, thus can reduce the coiling number of turns of half; Meanwhile, adopt Double-wire parallel wound, can reduce copper cash skin effect, resistance to big current, impulsive force is stronger, makes whole circuit power factor higher.In addition, be provided with the pedestal of band pin, make whole machine installation more simple and convenient, can be effectively cost-saving.
Description
Technical field
The utility model relates to a kind of power factor correction inductors, belongs to technical field of electronic components.
Background technology
At present, the power factor correction inductors that domestic and international household electrical appliance use, is adopt the coiling of single magnet ring single line, namely on a magnet ring, uses solid wire coiling, insert in circuit board after scolding tin.This traditional power factor correction inductors effective permeability is lower, magnetic loss is larger, for certain inductance value, need the number of turns of coiling more, the human cost that hand winding expends is larger, and because the volume of product is comparatively large, when big current, temperature rise can increase, directly use lead-out wire plug-in unit, inconvenient whole machine installation.
Utility model content
The purpose of this utility model is, provides a kind of power factor correction inductors, to solve above-mentioned technical problem.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of power factor correction inductors, comprises inductor body, and described inductor body comprises magnet ring and is wrapped in the winding on magnet ring; It is characterized in that: described magnet ring is formed by stacking with one heart by the identical magnet ring of size and No. two magnet rings; Described winding adopts the mode of Double-wire parallel wound to be wound on magnet ring; The bottom of described inductor body is provided with pedestal, and described pedestal is bonded and fixed at the bottom of inductor body by epoxy glue layer; The bottom even of described pedestal is provided with several pins; Each lead end of described winding is welded and fixed with each pin respectively.
Beneficial effect: compared with prior art, the utility model adopts two magnet ring superposition coiling, can reduce the volume of whole product, and increase magnetic core saturation flux density and net sectional area increase, inductive factor doubles, thus can reduce the coiling number of turns of half; Meanwhile, adopt Double-wire parallel wound, can reduce copper cash skin effect, resistance to big current, impulsive force is stronger, makes whole circuit power factor higher.In addition, be provided with the pedestal of band pin, make whole machine installation more simple and convenient, can significantly improve complete machine production efficiency, can be effectively cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
With reference to Fig. 1, power factor correction inductors described in the utility model, comprises inductor body, and described inductor body comprises magnet ring and is wrapped in the winding 2 on magnet ring.
Described magnet ring is formed by stacking with one heart by the identical magnet ring 11 of size and No. two magnet rings 12, can reduce the volume of whole product, increases magnetic core saturation flux density and net sectional area increases, and inductive factor doubles, and can reduce the coiling number of turns of half.
Described winding 2 adopts the mode of Double-wire parallel wound to be wound on magnet ring.Can reduce copper cash skin effect, resistance to big current, impulsive force is stronger, makes whole circuit power factor higher.Meanwhile, adopt pneumatic type crochet hook winding mode, the labour intensity of hand wound can be reduced.
The bottom of described inductor body is provided with pedestal 4, and described pedestal 4 is bonded and fixed at the bottom of inductor body by epoxy glue layer 3; The bottom even of described pedestal 4 is provided with several pins 5; Each lead end of described winding 2 is welded and fixed with each pin 5 respectively.With the pedestal of pin, whole machine installation can be made more simple and convenient, can significantly improve complete machine production efficiency, can be effectively cost-saving.
