Description
Technical field
The utility model is related to inductor field, more particularly, to a kind of common-mode inductor.
Background technology
In the market, the common mode inductance being operated in double-circuit communication circuit is separate design, using two identicals
Common mode inductance is filtered, not only relatively costly, and relatively low to the utilization rate of magnetic core, and EMC filter effects are poor, and two inductance hold
Easily interact generation resonance.
Utility model content
Regarding to the issue above, the utility model provides a kind of common-mode inductor, and it can be effectively reduced inductor
Cost, improves the magnetic core utilization rate of inductor, moreover it is possible to ensure good EMC effects.
The utility model is by the technical scheme that solution its technical problem is used：
A kind of common-mode inductor, including base, are provided with magnetic core on the base, the magnetic core is cylindrical shape, the magnetic
A two-way electric current winding and two single channel electric current windings are provided with core, the two-way electric current winding is wrapped on magnetic core
End, described two single channel electric current windings are respectively wound around magnetic core or so two ends, two two-way electric currents are provided with the base and are connected
Joint and four single channel electric current connectors, the two ends wire of the two-way electric current winding connect two two-way electric current connections respectively
Head, the two ends wire of described two single channel electric current windings connects four single channel electric current connectors respectively.
Used as the further improvement of such scheme, the two ends wire of the two-way electric current winding passes through fixing glue and two-way
Electric current connector is connected, and the two ends wire of the single channel electric current winding is connected by fixing glue with single channel electric current connector.
Used as the further improvement of such scheme, the wire of the two-way electric current winding and single channel electric current winding is arranged with
Insulating sleeve.
Used as the further improvement of such scheme, four single channel electric current connector is separately positioned on four angles of base
On, described two two-way electric current connectors are separately positioned on the both sides of the edge of base.
The beneficial effects of the utility model are：This common-mode inductor be provided with its magnetic core a two-way electric current winding with
And two single channel electric current windings so that two inductance can be united two into one, the utility model can not only reduce inductor into
This, and operationally, moreover it is possible to the magnetic core utilization rate of inductor is more effectively improved, and is kept away due to instead of two inductance
Exempting from two inductance produces resonance, this common-mode inductor to can guarantee that good EMC effects.
