Abstract
The energy-conservation FERRITE CORE of a kind of high coiling ratio, comprise hollow cylinder core body, annular rounded groove is opened respectively in the upper and lower surface of core body, and core outside diameter is 20mm, and internal diameter is 10mm, is highly 7mm; The difference of circular groove external diameter and internal diameter is 3.5mm, and the degree of depth is 1mm.The energy-conservation FERRITE CORE of the utility model height coiling ratio decreases the impact of stress on coil inductance of magnet ring, improve the magnetic permeability of inductance coil, achieve under same condition and reduce the effect that copper cash consumption reaches identical coil inductance, reduce material and save artificial.
Description
Technical field
The utility model relates to a kind of FERRITE CORE, particularly relates to the energy-conservation FERRITE CORE of a kind of high coiling ratio.
Background technology
What ferrite inductance was mainly used in electric power system in radio frequency and microwave circuit moves back lotus root, the moving back lotus root and prevent from being formed by power supply the bad coupling of inter-stage of high-speed digital circuit electric power system.Ferrite inductance is primarily of FERRITE CORE, copper cash wire harness composition, FERRITE CORE one-turn coil inductance value determines the inductance value of multi-turn coiling, the ratio of conventional FERRITE CORE multi-turn and individual pen is between 0.9-1.2, the inductance coil of high inductance value will be obtained at the inductance coil of design one fixing turn, must have the FERRITE CORE of high individual pen inductance otherwise overall dimension and the copper cash cost that winding turns which adds inductance coil must be increased, and the FERRITE CORE of high coiling ratio (ratio is greater than 1.4) just well addresses this problem.
Summary of the invention
The utility model is that providing a kind of for the deficiencies in the prior art can not have an impact in situation for reducing the energy-conservation FERRITE CORE of high coiling ratio of the volume of inductor to perimeter circuit element.
For achieving the above object, the technical scheme that the utility model is taked is:
The energy-conservation FERRITE CORE of a kind of high coiling ratio, comprise hollow cylinder core body, annular rounded groove is opened respectively in the upper and lower surface of described core body.
Described core outside diameter is 20mm, and internal diameter is 10mm, is highly 7mm; The difference of described circular groove external diameter and internal diameter is 3.5mm, and the degree of depth is 1mm.
The beneficial effect that the energy-conservation FERRITE CORE of the utility model height coiling ratio realizes is: by decreasing the copper cash of coil and the contact area of magnetic core at hollow cylinder magnetic core upper and lower surface fluting thus decreasing the impact of stress on coil inductance of magnet ring, improve the magnetic permeability of inductance coil, improve more than 1.4 times compared with original inductance coil magnetic permeability, achieve under same condition and reduce the effect that copper cash consumption reaches identical coil inductance, reducing material saves artificial, thus reaches energy-saving and cost-reducing object.

1, core body, 2, circular groove.
Embodiment
As shown in Figure 1, 2, the energy-conservation FERRITE CORE of a kind of high coiling ratio, comprises hollow cylinder core body 1, and annular rounded groove 2 is opened on the upper and lower surface of core body 1 respectively.Core body 1 external diameter is 20mm, and internal diameter is 10mm, is highly 7mm; The difference of circular groove 2 external diameter and internal diameter is 3.5mm, and the degree of depth is 1mm.
The energy-conservation FERRITE CORE of the utility model height coiling ratio is by decreasing the copper cash of coil and the contact area of magnetic core at hollow cylinder magnetic core upper and lower surface fluting thus decreasing the impact of stress on coil inductance of magnet ring, improve the magnetic permeability of inductance coil, improve more than 1.4 times compared with original inductance coil magnetic permeability, achieve under same condition and reduce the effect that copper cash consumption reaches identical coil inductance, reducing material saves artificial, thus reaches energy-saving and cost-reducing object.
To enclose copper cash for radix around 10:
Normal coil inductance coiling ratio=coil inductance divided by coil quantity square divided by magnetic core individual pen inductance=0.9-1.0;
After fluting magnetic coil inductor coiling ratio=coil inductance divided by coil quantity square divided by magnetic core individual pen inductance > 1.4.
