Abstract
The invention discloses a low-inductance large-current inductor. In order to overcome the defects that an existing low-inductance inductor coil is difficult to wind, low in production efficiency, poor in performance and the like, a magnetic core is composed of two auxiliary magnetic cores, n-shaped grooves for installing an n-shaped coil are correspondingly formed in the attaching faces of the two auxiliary magnetic cores, the coil is formed by a solid wire adapting to the n-shaped grooves, and the cross section of the solid wire is rectangular. The inductor is mainly used for the fields of power supplies, uninterruptible power supplies, household appliance control panels and the like. More materials are saved, the coil can be formed through a mold or formed in a press mode, the working procedures of wire winding, tin soldering and the like can be omitted, the inductor is convenient to machine and high in uniformity and stability, the coil is assembled in the magnetic core, coupling is better, and performance is remarkably improved.
Description
Technical field
The present invention relates to a kind of inducer being used in the fields such as power supply unit, uninterrupted power supply (ups) Unity, household electrical appliance panel, a kind of low inductance high-current inductor.
Background technology
The inducer of existing low inductance, the coiling number of turns of its coil is less, but is generally used for big current domain.Traditional low inductance high-current inductor flat wire coiling, then assemble Mn ferrite, but because electric current is relatively big, the line footpath of usual coil is very big, and coil is not easy coiling very much, and production efficiency is low, and coil performance is poor；Bigger due to line footpath again so that whole inducer volume increases, and takes up room many.
Summary of the invention
The purpose of the present invention is aiming at above-mentioned deficiency, a kind of low inductance high-current inductor is provided, it more saves material, and coil can save the operation such as coiling and scolding tin with mould molding or punch forming, easy to process, concordance is good, good stability, and coil groups is contained in magnetic core, more preferably, performance significantly improves in coupling.
For reaching above-mentioned purpose, the technical scheme is that, this low inductance high-current inductor, including the magnetic core of installation coil, described magnetic core has the groove installing coil, and described coil is made up of the single cord adapting to this groove.
Described magnetic core has the concave shape groove installing coil, and described coil is made up of the single cord adapting to this concave shape groove.
Described magnetic core has the concave shape groove installing coil, and described coil is made up of the single cord adapting to this concave shape groove, and the cross section of this single cord is polygon.
Described magnetic core is made up of two sub-magnetic cores, and the binding face correspondence at these two sub-magnetic cores has offered the concave shape groove installing concave shape coil, and described coil is made up of the single cord adapting to this concave shape groove, and the cross section of this single cord is rectangle.
Coil of the present invention uses copper sheet or copper coin punch forming instead, and magnetic core is made up of two sub-magnetic cores, binding face correspondence at these two sub-magnetic cores has offered the concave shape groove installing concave shape coil, described coil is made up of the single cord adapting to this concave shape groove, the cross section of this single cord is rectangle shape, this cross section is rectangle or square concave shape coil, it is arranged between two sub-magnetic cores, so magnetic core couples with coil and reaches maximum, couple, inductance performance improves, corresponding wire circle is reduced to minimum (coil of individual pen) and coil can be with mould molding or with copper sheet, copper coin punch forming, coil and magnetic core simple and convenient assembly, hurry up, the operation such as coiling and scolding tin can be saved, easy to process, concordance is more preferable, stability is more preferable；Coil groups is contained in magnetic core, and more preferably, performance improvement, finished size is farthest reduced, easy to assembly, and processing technique reduces, and production efficiency is high in coupling.
Present invention is mainly used for the inducer in the fields such as power supply unit, uninterrupted power supply (ups) Unity, household electrical appliance panel, it more saves material, coil can be with mould molding or punch forming, can save the operation such as coiling and scolding tin, easy to process, concordance is good, good stability, coil groups is contained in magnetic core, and more preferably, performance significantly improves in coupling.
Accompanying drawing explanation
Fig. 1 is the schematic top plan view that after the present invention removes one of them sub-magnetic core, coil is installed on another sub-magnetic core.
Fig. 2 is the line A-A cross sectional representation that two sub-magnetic cores of the present invention constitute tailing edge Fig. 1.
In figure, 1. magnetic core, 2. coil.
Detailed description of the invention
As shown in Figure 1, 2, this low inductance high-current inductor, including the magnetic core 1 installing coil 2, magnetic core 1 has the groove installing coil 2, coil 2 is made up of the single cord adapting to this groove, and magnetic core 1 is made up of two sub-magnetic cores, and the binding face correspondence at these two sub-magnetic cores has offered the concave shape groove installing concave shape coil 2, coil 2 is made up of the single cord adapting to this concave shape groove, and the cross section of this single cord is rectangle.
Another embodiment: in magnetic core 1, the groove of installation coil 2 with right and wrong concave shape groove, can adapt to the coil 2 of this non-concave shape groove is that single cord is constituted, and the cross section of this single cord can be non-rectangular polygon.
