Abstract

The utility model discloses a kind of low inductance high-current inductor.In order to the inductor coil coiling overcoming existing low inductance is difficult, production efficiency is low, the deficiencies such as coil performance difference, magnetic core described in the utility model is made up of two sub-magnetic cores, the concave shape groove installing concave shape coil has been offered in the binding face correspondence of these two sub-magnetic cores, 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.The utility model is mainly used in the inductor in the fields such as power supply unit, uninterrupted power supply, household electrical appliance control board, it saves material more, coil can mould molding or punch forming, can save the operation such as coiling and scolding tin, easy to process, consistency is good, good stability, coil groups is contained in magnetic core, and coupling is better, and performance is significantly improved.

Description

Low inductance high-current inductor
Technical field
The utility model relates to a kind of inductor being used in the fields such as power supply unit, uninterrupted power supply (ups) Unity, household electrical appliance control board, is specially a kind of low inductance high-current inductor.
Background technology
The inductor of existing low inductance, the coiling number of turns of its coil is less, but is usually used in big current field.Traditional low inductance high-current inductor flat wire coiling, then assemble Mn ferrite, but because of electric current comparatively large, the wire diameter of usual coil is very large, and coil is very not easy coiling, and production efficiency is low, and coil performance is poor; Again because wire diameter is comparatively large, whole inductor volume is increased, takes up room many.
Utility model content
The purpose of this utility model is exactly for above-mentioned deficiency, a kind of low inductance high-current inductor is provided, it saves material more, and coil can mould molding or punch forming, can save the operation such as coiling and scolding tin, easy to process, consistency is good, good stability, and coil groups is contained in magnetic core, coupling is better, and performance is significantly improved.
For achieving the above object, the technical solution of the utility model is, this low inductance high-current inductor, comprises the magnetic core installing coil, and 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 offered in the binding face correspondence of these two sub-magnetic cores the concave shape groove installing concave shape coil, 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.
The utility model coil uses copper sheet or copper coin punch forming instead, and magnetic core is made up of two sub-magnetic cores, the concave shape groove installing concave shape coil has been offered in the binding face correspondence of these two sub-magnetic cores, 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, be arranged between two sub-magnetic cores, such magnetic core and coil coupling reach maximum, be coupled, inductance performance improves, corresponding wire circle is reduced to minimum (coil of individual pen) and coil can 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, consistency is better, stability is better, coil groups is contained in magnetic core, and coupling is better, performance improvement, and finished size is farthest reduced, easy to assembly, and processing technology reduces, and production efficiency is high.
The utility model is mainly used in the inductor in the fields such as power supply unit, uninterrupted power supply (ups) Unity, household electrical appliance control board, it saves material more, coil can mould molding or punch forming, can save the operation such as coiling and scolding tin, easy to process, consistency is good, good stability, coil groups is contained in magnetic core, and coupling is better, and performance is significantly improved.
Accompanying drawing explanation
Fig. 1 is the schematic top plan view that after the utility model removes one of them sub-magnetic core, coil is installed on another sub-magnetic core.
Fig. 2 is the A-A line cross sectional representation along Fig. 1 after the sub-magnetic core of the utility model two is formed.
In figure, 1. magnetic core, 2. coil.
Embodiment
As shown in Figure 1, 2, this low inductance high-current inductor, comprise 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, has offered in the binding face correspondence of these two sub-magnetic cores 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 kind of execution mode: the groove installing coil 2 in magnetic core 1 can be non-concave shape groove, adapt to the coil 2 of this non-concave shape groove for single cord formation, the cross section of this single cord can be non-rectangular polygon.
