Abstract
The utility model discloses a kind of magnetic bar type common mode inductance, including：One U-shaped magnetic core, the first groove is prepared on facade in the first of the U-shaped magnetic core；The second groove is being prepared in second on facade；One bar magnet, the length of the bar magnet are just embedded between the first groove and the second groove；There is coil on the bar magnet.Compared with prior art, the production of magnetic bar type common mode inductance of the present utility model is very easy, and prior coiling is finished, and then coil is enclosed on bar magnet, then bar magnet is embedded between the first groove and the second groove, is cemented with glue；The utility model is wide in variety, and production efficiency is high, cost is cheap.
Description
Technical field
Electronic component, more particularly to a kind of core inductance are the utility model is related to, particularly a kind of magnetic bar type common mode electricity
Sense.
Background technology
In the prior art, there are a various common mode inductances, such as Emerson Network Power CO., Ltd's application
No. 201320210590.1, a kind of entitled utility model patent of inductor, a kind of inductance is disclosed in its technical scheme
Device：Including：Common mode inductance, the common mode inductance include common mode inductance magnetic core and are wound on the common mode inductance magnetic core and be at least two common
Mould inductor winding, the inductor also include magnetic sheet, and the magnetic sheet is attached at least one common mode inductance winding.
As can be seen that the patented technology volume is excessive, be not suitable for using on micro device.
In addition, the material manufacture such as magnetic core and skeleton of current common mode inductance generally use magnet ring, UU structures, using magnet ring
Common mode inductance artificial coiling is difficult in process of production, it is also very low using the production efficiency of special coil winding machine, in particular for
Difficulty is bigger when comparing thick enamel-covered wire, the common mode inductance of UU structures, because the window of skeleton is smaller, the number of turns and line footpath of coiling
It is limited by very large, while the price of these common mode inductances is also higher, meets to want therefore, it is necessary to design a kind of effect
Ask, the low common mode inductance of production efficiency height, strong applicability, cost.
Utility model content
The purpose of this utility model is in the prior art " using the common mode inductance people in process of production of magnet ring
Work coiling is difficult, also very low using the production efficiency of special coil winding machine, and difficulty is bigger during in particular for thicker enamel-covered wire,
The common mode inductance of UU structures, because the window of skeleton is smaller, the number of turns and line footpath of coiling are limited by very large." deficiency
And provide a kind of magnetic bar type common mode inductance.
The utility model is realized by using following technical scheme.
Manufacture and design a kind of magnetic bar type common mode inductance, the common mode inductance includes：
One U-shaped magnetic core, the first groove is prepared on facade in the first of the U-shaped magnetic core；Prepared in second on facade
Second groove；
One bar magnet, the length of the bar magnet are just embedded between the first groove and the second groove；
There is coil on the bar magnet.
Coil on the bar magnet has two.
Four the end of a thread of the coil are all drawn to the lower section of U-shaped magnetic core.
Compared with prior art, the production of magnetic bar type common mode inductance of the present utility model is very easy, prior coiling line
Circle is finished, and then coil is enclosed on bar magnet, then bar magnet is embedded between the first groove and the second groove, is cemented with glue；
The utility model is wide in variety, and production efficiency is high, cost is cheap.
Brief description of the drawings
The utility model is further detailed below with accompanying drawing, but the embodiment in accompanying drawing is not formed pair
Any restrictions of the present utility model.
Fig. 1 is the schematic perspective view of U-shaped magnetic core in magnetic bar type common mode inductance of the present utility model；
Fig. 2 is the schematic perspective view of magnetic bar type common mode inductance coil of the present utility model；
Fig. 3 is the schematic diagram that a coil is cased with the bar magnet in magnetic bar type common mode inductance of the present utility model；
Fig. 4 is the schematic perspective view that two coils are cased with the bar magnet in magnetic bar type common mode inductance of the present utility model.
Embodiment
The utility model is illustrated with reference to specific embodiment.
As shown in Figure 1 to 4, a kind of magnetic bar type common mode inductance is manufactured and designed, the common mode inductance includes：
One U-shaped magnetic core 1, the first groove 12 is prepared on facade 11 in the first of the U-shaped magnetic core 1；The facade in second
The second groove is prepared on 13；
One bar magnet 3, the length of the bar magnet 3 are just embedded between the first groove 12 and the second groove；
There is coil 2 on the bar magnet 3.
Coil 2 on the bar magnet 3 has two.
Four the end of a thread 21 of the coil 2 are all drawn to the lower section of U-shaped magnetic core 1.
As shown in Figure 1 to 4：Its core material is identical with bar magnet 3 for the U-shaped magnetic core 1 of this common mode inductance, can also be different,
The two can be bonded firm with glue.
The enamel-cover linear diameter of coil 2, the number of turns, around to etc. it is identical.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
With new thought, there will be changes, this specification content should not be construed as in specific embodiments and applications
To limitation of the present utility model.
